Using these systems, the electrical energy storage of electric vehicles can be supplied with electrical energy to charge it. For example, battery cells in electrical energy storage systems can be charged with direct current (DC). For instance, a charger in the electric vehicle can be used that, during AC charging or three-phase charging, converts the alternating current supplied by a charging station into the direct current required by the electrical energy storage system. This process, also known as rectification, allows the electrical energy storage system to be charged.In so-called direct current (DC) charging, direct current from the charging station is fed directly into the vehicle, with the DC current being supplied by a charger at the charging station. Generally, it is desirable for electric vehicle charging networks to be designed with a particularly simple construction and robust operation.

[0009] As already described, each first distribution unit of the at least one first distribution unit has the electrical connection unit with which the first distribution unit can be connected to the third distribution unit of the electrical charging network system, which is set up to provide electrical energy with an electrical voltage at a first voltage level, or to a component of a first voltage level, in such a way that the first distribution unit can be supplied with electrical energy with an electrical voltage at a first voltage level.By having each first distribution unit of at least one first distribution unit the electrical connection unit with which the first distribution unit can be connected to the third distribution unit of the electrical charging network system, which is configured to provide electrical energy with an electrical voltage at a first voltage level, or to a component of a first voltage level, in such a way that the first distribution unit can be supplied with electrical energy with an electrical voltage at a first voltage level, it is ensured that each first distribution unit can be supplied with electrical energy for charging electrical energy storage devices of electric vehicles.

[0010] As already described, each first distribution unit is set up to provide electrical energy with the electrical voltage at the second voltage level, and each second distribution unit of the at least one second distribution unit is connected to the corresponding first distribution unit in such a way that the second distribution unit can be supplied with electrical energy with the electrical voltage at the second voltage level.By configuring each first distribution unit to provide electrical energy at the second voltage level, and by connecting each second distribution unit to the corresponding first distribution unit in such a way that the second distribution unit can be supplied with electrical energy at the second voltage level, it is ensured that the electrical energy at the second voltage level can be used to charge the electrical energy storage of electric vehicles using other components of the electric charging network system, such as the at least one second distribution unit and the at least one charging point unit. Preferably, the second voltage level is a medium voltage level. Preferably, the second voltage level corresponds to the first voltage level.

[0011] As already described, every second distribution unit is set up to provide electrical energy with the electrical voltage at the third voltage level, and each charging point unit of the at least one charging point unit is connected to the corresponding second distribution unit in such a way that the charging point unit can be supplied with electrical energy with the electrical voltage at the third voltage level.By configuring every second distribution unit to supply electrical energy at the third voltage level, and by connecting each charging point unit of the at least one charging point unit to the corresponding second distribution unit in such a way that the charging point unit can be supplied with electrical energy at the third voltage level, it is ensured that the electrical energy at the third voltage level can be used to charge electric vehicle energy storage devices using other components of the electric charging network system, such as the at least one charging point unit. Preferably, the third voltage level is a low-voltage level.Preferably, in connection with the present invention, a low-voltage level is defined such that when electrical energy is supplied at a voltage at the low-voltage level, or a component can be supplied with electrical energy at a voltage at the low-voltage level, the voltage at the low-voltage level corresponds to a nominal voltage of 0.4 kV (400 V). Preferably, every second distribution unit converts the voltage at the medium-voltage level to a voltage at the low-voltage level. Preferably, several charging point units are provided, which are connected to a corresponding second distribution unit by means of stem cabling or ring cabling.Preferably, several charging point units are provided, which are connected to a corresponding second distribution unit for the supply of electrical energy by means of a star wiring or a ring wiring.

[0012] As previously described, each charging point unit of the at least one charging point unit has the connection section to which the electric vehicle's electrical energy storage device can be connected, so that the electric vehicle's electrical energy storage device can be charged with electrical energy. Because each

[0013] A charging point unit, which has at least one connection section with which the electric vehicle's electrical energy storage can be connected so that the electric vehicle's electrical energy storage can be charged with electrical energy, ensures that a connected state between the connection section of each charging point unit and an electric vehicle's electrical energy storage can be established, for example by means of a charging cable, in which the electric vehicle's electrical energy storage can be supplied with electrical energy and thus charged.

[0014] The electric charging network system is therefore structured such that each first distribution unit can be supplied with electrical energy by the third distribution unit or by the component of the first voltage level; each first distribution unit can supply a second distribution unit or several corresponding second distribution units to at least one second distribution unit; and each third distribution unit can supply a charging point unit or several corresponding charging point units to at least one charging point unit. Each charging point unit is thus assigned to a specific second distribution unit, namely the second distribution unit that supplies the corresponding charging point unit with electrical energy.Similarly, every second distribution unit is assigned to a specific first distribution unit, namely the first distribution unit that supplies the corresponding second distribution unit with electrical energy. Furthermore, every first distribution unit is preferentially assigned to the third distribution unit, since the third distribution unit preferentially supplies every second distribution unit with electrical energy.

[0015] As previously described, each first distribution unit has a first data processing unit. In particular, each first data processing unit has a processor and a data storage unit. The fact that each first distribution unit has a first data processing unit ensures that each first data processing unit can process data. As previously described, each charging point unit has a charging data processing unit. In particular, each charging data processing unit has a processor and a data storage unit. The fact that each charging point unit has a charging data processing unit ensures that each charging point unit can process data.

[0016] As already described, each charging point unit of the at least one charging point unit is connected to the corresponding first distribution unit in such a way that the first data can be sent from the first data processing unit, the first data can be received from the charging data processing unit, the charging data can be sent from the charging data processing unit, and the charging data can be received from the first

[0017] Data processing units can receive data. In particular, in connection with the present invention, data sent by the first data processing unit and received by the loading data processing unit are referred to as first data. The first data may, for example, have a status of "OK", which may consist of a "0" (zero). Furthermore, the third data may, for example, have a status of "not OK", which may consist of a "1" (one). The first data is preferably received by the loading data processing unit and stored in a data memory of the loading data processing unit.Preferably, the first data is read from the data memory of the first data processing unit by the processor of the first data processing unit and sent by the processor of the first data processing unit to a transmit and receive unit of the first distribution unit, and then sent by the transmit and receive unit of the first distribution unit to a transmit and receive unit of the charging point unit. The transmit and receive unit of the charging point unit then sends the first data to the processor of the charging point unit, which stores the first data in the data memory of the charging data processing unit. In particular, in connection with the present invention, data sent by the charging data processing unit and received by the first data processing unit are referred to as charging data.The charging data, for example, includes a combination of a unique identification number for a connection section of a charging point unit and a unique identification number for the driver. Preferably, the charging data is read from the charging data processing unit's data memory by the charging data processing unit's processor and sent by the charging data processing unit's processor to a transmit / receive unit of the charging data processing unit. This transmit / receive unit then sends the data to a transmit / receive unit of the first distribution unit. The transmit / receive unit of the first distribution unit then sends the charging data to the processor of the first data processing unit, which stores the charging data in the first data processing unit's data memory.By connecting each charging point unit of at least one charging point unit to the corresponding first distribution unit in such a way that the first data can be sent from the first data processing unit, the first data can be received from the charging data processing unit, the charging data can be sent from the charging data processing unit and the charging data can be received from the first data processing unit, it is ensured that the possibility of data exchange between each charging point unit and the corresponding first distribution unit is guaranteed.

[0018] A significant advantage of the present invention compared to electrical charging network systems known from the prior art is that, in the electrical charging network system according to the invention, both every second distribution unit is connected to a corresponding first distribution unit and every charging point unit is connected to a corresponding second distribution unit in such a way that each charging point unit can provide electrical energy for charging electrical energy storage devices of electric vehicles by transferring the electrical energy from a corresponding first distribution unit via a corresponding second distribution unit to a corresponding charging point unit, and each charging point unit is also connected to a corresponding first distribution unit in such a way thatthat data exchange is ensured from a corresponding first distribution unit to a corresponding charging point unit and from each charging point unit to a corresponding first distribution unit. This is achieved by enabling, with the help of the charging network system according to the invention, both a supply of electrical energy from the at least one first distribution unit via the at least one second distribution unit to the at least one charging point unit for charging electrical energy storage devices of electric vehicles, and also ensuring data exchange between the charging point units and the first distribution units.The supply of electrical energy between the individual components of the electric charging network system and the data exchange between the individual components of the electric charging network system are independent of existing electricity distribution networks outside the electric charging network system and independent of existing data exchange facilities outside the electric charging network system, such as the internet. The electric charging network system can also be described as a closed and, in particular, self-sufficient energy and data network. Furthermore, each first distribution unit and each charging point unit is configured to supply another corresponding component with electrical energy or to be supplied with electrical energy by another corresponding component, as well as to exchange data with another corresponding component or with several other components.This significantly simplifies the expansion of the electric vehicle charging network, as only one component needs to be installed, and this single component already provides both power supply and data exchange. For example, wired connections can be used for the,

[0019] Power supply and data exchange can be laid together, significantly reducing the amount of excavation required. Furthermore, centralized control of the charging point units is possible via a dedicated first distribution unit. Maintenance of the electric charging network system is also considerably simplified, as individual components, each responsible for both power supply and data exchange, can be replaced.

Preferably, in connection with the present invention, a low-voltage level is defined such that when electrical energy is supplied at an electrical voltage at the low-voltage level, or a component can be supplied with electrical energy at an electrical voltage at the low-voltage level, the electrical voltage at the low-voltage level corresponds to a nominal voltage of 0.4 kV (400 V).In the electrical charging network system 1 shown in Figure 1, in the electrical charging network system 1 shown in Figure 2, in the electrical charging network system 1 shown in Figure 6, and in the electrical charging network system 1 shown in Figure 7, every second distribution unit 7 converts the electrical voltage at the medium-voltage level to an electrical voltage at the low-voltage level.

In both the first embodiment of the electrical charging network system 1 shown in Figure 1 and the second embodiment of the electrical charging network system 1 shown in Figure 2, the component 17 of the fourth voltage level is therefore a component of a high-voltage level, and the third distribution unit 11 can be supplied with electrical energy at a voltage at the high-voltage level.Preferably, a transfer station is provided between component 17 of the fourth voltage level and the third distribution unit 11. The transfer station can also be referred to as a network transfer point. The network transfer point can preferably supply up to 2750 charging point units with electrical energy.

In the electrical charging network system 1 shown in Figure 2, component 15 of the first voltage level is a transformer station, which can also be referred to as a transformer substation. In the electrical charging network system 1 shown in Figure 2, component 15 of the first voltage level is a component of a medium-voltage level, and the first distribution unit 5 can be supplied with electrical energy at a voltage on the medium-voltage level.The electrical charging network system 1 shown in Figure 2 can also be referred to as an integrated electrical charging network system 1.

[0060] In the third embodiment of the electrical charging network system 1 shown in Figure 6 and in the fourth embodiment of the electrical charging network system 1 shown in Figure 7, one component 17 of the several components of the fourth voltage level is a device for converting renewable energy into electric current, such as a solar park, which can also be referred to as a photovoltaic open-field system and can be regarded as an example of an energy park, and the fourth voltage level is a medium voltage level.In both the third embodiment of the electrical charging network system 1 shown in Figure 6 and the fourth embodiment of the electrical charging network system 1 shown in Figure 7, each component 17 of the fourth voltage level is therefore a component of a medium-voltage level, and the third distribution unit 11 can be supplied with electrical energy at a voltage on the medium-voltage level.

[0067] As already described, Figure 3 shows a schematic representation of an embodiment of an electrical infrastructure system 3 according to the invention. The electrical infrastructure system 3 comprises several electrical charging network systems. Each electrical charging network system 1 is one of the electrical charging network systems 1 shown in Figure 1. Alternatively, each electrical charging network system 1 can be one of the electrical charging network systems 1 shown in Figure 2, one of the electrical charging network systems 1 shown in Figure 6, or one of the electrical charging network systems 1 shown in Figure 7. The component 17 of the fourth voltage level is thus the device for converting renewable energy into electricity, such as the solar park already described, and the fourth voltage level is a high-voltage level or a medium-voltage level.The third distribution unit 11 of each electrical charging network system 1 is connected to the renewable energy conversion facility, such as the solar park, in such a way that each third distribution unit 11 can be supplied with electrical energy at a voltage on the fourth voltage level. In Figure 3, the three dots symbolize that further electrical charging network systems are or can be provided via the electrical charging network systems shown in Figure 3.

[0068] As already described, Figure 4 shows a schematic representation of an embodiment of a method according to the invention for operating an electric charging network system 1. In a first method step 101, the electrical connection unit of the first distribution unit 5 is connected to a third distribution unit 11 of the electric charging network system 1 or to a component 15 of a first voltage level such that the first distribution unit 5 is supplied with electrical energy at an electrical voltage on the first voltage level. In a second method step 102, at least one second distribution unit 7 is connected to a corresponding first distribution unit 5 such that the at least one second distribution unit 7 is supplied with electrical energy at an electrical voltage on the second voltage level.In a third process step 103 of the method, at least one charging point unit 9 is connected to a corresponding second distribution unit 7 such that the at least one charging point unit 9 is supplied with electrical energy at an electrical voltage on the third voltage level. In a fourth process step 104 of the method, a charging process is carried out, which is described in more detail below. Figure 5 shows a schematic representation of a charging point unit 9 for the first embodiment of the electrical charging network system 1 according to the invention and for the second embodiment of the electrical charging network system 1 according to the invention. The charging process already mentioned is described below with reference to Figure 5.Preferably, a charging process can also be carried out using each charging point unit 9 of both the third embodiment of the electrical charging network system 1 according to the invention and the fourth embodiment of the electrical charging network system 1 according to the invention.

[0069] For example, if a driver 19 of an electric vehicle 13, as shown in Figure 5, wants to charge the electrical energy storage of his electric vehicle 13, he drives his electric vehicle 13 to a connection section of a charging point unit 9. The driver 19 scans a QR code 23, which is attached to the charging point unit 9 and which has a unique identification number (UIN) in coded form, with the unique identification number uniquely identifying the connection section of the charging point unit 9.Using an app installed on the driver's mobile phone 21, the unique identification number of the connection section of the charging point unit 9 can be determined from the scanned QR code 23, and the driver 19 can confirm by user input that they wish to charge the electrical energy storage of their electric vehicle 13 at the connection section of the charging point unit 9. The process is described below using an app. However, other applications are also possible in connection with the present invention, such as a digital wallet provided in the mobile phone 21. After user input, the driver's mobile phone 21 wirelessly transmits the unique identification number of the connection section of the charging point unit 9 and a unique identification number of the driver 19 stored in the driver's app to a transmitter and receiver unit 25 for wireless transmission and reception by the charging point unit 9.Preferably, the driver's mobile phone 21 19 wirelessly transmits the unique identification number of the connection section of the charging point unit 9 and a unique identification number of the driver 19 stored in the driver's app 19 to a transmitter and receiver unit 25 for wireless transmission and reception of the charging point unit 9 using Near Field Communication (NFC). Preferably, the transmitter and receiver unit 25 for wireless transmission and reception of the charging point unit 9 is an NFC transmitter and receiver unit. The transmitter and receiver unit 25 for wireless transmission and reception sends the unique identification number of the connection section of the charging point unit 9 and the unique identification number of the driver 19 to a processor 27 of the charging point unit 9, which is connected to a data storage device 29 of the charging point unit 9.The combination of processor 27 and data storage 29 can also be referred to as a loading data processing unit. The loading data processing unit thus comprises processor 27 of the loading point unit 9 and data storage 29 of the loading point unit 9. Processor 27 then reads the unique identification numbers of the two connection sections of the loading point unit 9 stored in data storage 29 and compares them.

[0070] Connection sections of the charging point unit 9 with the unique identification number of the connection section of the charging point unit 9 sent by the transmitter and receiver unit 25 to the processor 27 of the charging point unit 9 for wireless transmission and reception. If one of the two unique identification numbers of the two connection sections of the charging point unit 9 stored in the data memory 29 of the charging point unit 9 and the unique identification number of the connection section of the charging point unit 9 sent by the transmitter and receiver unit 25 to the processor 27 of the charging point unit 9 for wireless transmission and reception matches, the processor 27 of the charging point unit 9 sends the unique identification number of the connection section of the charging point unit 9 and the unique identification number of the driver 19 to a transmitter and receiver unit 31 of the charging point unit 9.The combination of the unique identification number of the connection section of the charging point unit 9 and the unique identification number of the driver 19 can also be referred to as charging data. The transmitter and receiver unit 31 of the charging point unit 9 now transmits the unique identification number of the connection section of the charging point unit 9 and the unique identification number of the driver 19 via the previously described wired connection between the charging point unit 9 and the first distribution unit 5 assigned to the charging point unit 9, which is formed by an electrically conductive cable between the charging point unit 9 and the first distribution unit 5, to a transmitter and receiver unit of the first distribution unit 5. The connection formed by the electrically conductive cable extends from the charging point unit 9 to the first distribution unit 5.In particular, no data exchange takes place between each charging point unit 9 and a second distribution unit 7 assigned to the corresponding charging point unit 9. Specifically, no direct data exchange takes place between each charging point unit 9 and the second distribution unit 7 assigned to the corresponding charging point unit 9, in which data is directly exchanged between each charging point unit 9 and a second distribution unit 7 assigned to the corresponding charging point unit 9.Because direct data exchange takes place between each charging point unit 9 and the second distribution unit 7 assigned to the corresponding charging point unit 9, the second distribution unit 7 can be designed in a particularly simple way, since in addition to the components for supplying electrical energy, no components are required for data communication with the charging point unit 9 or with the charging point units.

[0071] Data processing equipment must be provided. The transmitting and receiving unit of the first

[0072] Distribution unit 5 now transmits the unique identification number of the connection section of charging point unit 9 and the unique identification number of the driver 19 to a processor of the first distribution unit 5, which stores the unique identification number of the connection section of charging point unit 9 and the unique identification number of the driver 19 in a data memory of the first distribution unit 5. The processor of the first distribution unit 5 now reads the data stored in the data memory of the first distribution unit 5, which can also be referred to as reference data, and uses this data to check, i.e.,Based on the reference data, the system determines whether the unique identification number of the charging point unit 9 connection section, the unique identification number of driver 19, or a combination of both results in an "OK" or "Not OK" status. For example, the reference data might contain an error message related to the charging point unit 9 connection section selected by driver 19 because a charging attempt with this connection section was unsuccessful and a replacement of this connection section is already scheduled for the next few hours. In this case, the check would, for example, result in a "Not OK" status.

[0073] If the check results in an "OK" status, the processor of the first distribution unit 5 sends the "OK" status, which may consist of a "0" (zero), to the transmitter and receiver unit of the first distribution unit 5. This unit then transmits the "OK" status via the electrically conductive cable to the transmitter and receiver unit 31 of the charging point unit 9. The transmitter and receiver unit 31 of the charging point unit 9 then sends the "OK" status to the processor 27 of the charging point unit 9, which in turn sends the "OK" status to the transmitter and receiver unit 25 for wireless transmission and reception from the charging point unit 9. The transmitter and receiver unit 25 for wireless transmission and reception from the charging point unit 9 then sends the "OK" status to the mobile phone 21 and to the app installed on the mobile phone 21, which then displays a message indicating that the charging process can begin.

[0074] When the app installed on the mobile phone 21 displays the information that the charging process can be started, the driver 19 connects a charging cable to both the selected connection section of the charging point unit 9 and to the energy storage of the electric vehicle 13. A sensor unit of the charging point unit 9 now detects that a charging cable is connected to the selected connection section of the charging point unit 9 and sends this information, which can also be referred to as charging data, to the processor 27 of the charging point unit 9.The processor 27 of the charging point unit 9 sends the information that the charging cable is connected to the selected connection section of the charging point unit 9 to the transmitter and receiver unit 31 of the charging point unit 9. The transmitter and receiver unit 31 then sends this information via the wired connection between the charging point unit 9 and the first distribution unit 5 assigned to the charging point unit 9 to the transmitter and receiver unit of the first distribution unit 5. The transmitter and receiver unit of the first distribution unit 5 then forwards the information that the charging cable is connected to the selected connection section of the charging point unit 9 to the processor of the first distribution unit 5, which stores this information in a data memory of the first distribution unit 5.The first distribution unit 5 now provides the electrical energy required to charge the electric vehicle's electrical energy storage device 13 at the second voltage level, so that the second distribution unit 7 is supplied with electrical energy at the second voltage level. The second distribution unit 7 then provides the electrical energy at the third voltage level, so that the charging point unit 9 is supplied with electrical energy at the third voltage level, thus charging the electric vehicle's electrical energy storage device 13.

[0075] When the electric vehicle's energy storage system 13 is fully charged, the app installed on the driver's mobile phone 21 19 displays a message indicating that the driver 19 can confirm, via user input, that they wish to end the charging process. The mobile phone 21 wirelessly transmits this information to the wireless transmitting and receiving unit 25 of the charging point unit 9. The wireless transmitting and receiving unit 25 then sends this information to the processor 27 of the charging point unit 9. This information can also be referred to as charging data. The processor 27 of the charging point unit 9 then sends this information to the transmitting and receiving unit 31 of the charging point unit 9.The transmitter and receiver unit 31 of the charging point unit 9 now sends the information via the wired connection between the charging point unit 9 and the first distribution unit 5 assigned to the charging point unit 9 to the transmitter and receiver unit of the first distribution unit 5. The transmitter and receiver unit of the first distribution unit 5 then forwards this information to the processor of the first distribution unit 5, which stores the information that the driver 19 wants to end the charging process in the data memory of the first distribution unit 5.The first distribution unit 5 now ceases supplying the electrical energy required for charging the electric vehicle's electrical energy storage device 13 at the second voltage level, thus preventing the second distribution unit 7 from receiving the electrical energy required for charging the electric vehicle's electrical energy storage device 13 at the second voltage level. The second distribution unit 7 also now ceases supplying the electrical energy required for charging the electric vehicle's electrical energy storage device 13 at the third voltage level, thus preventing the charging point unit 9 from receiving the electrical energy required for charging the electric vehicle's electrical energy storage device 13 at the third voltage level.As already described in connection with the start of charging, the processor of the first distribution unit 5 now sends an "OK" status to the processor 27 of the charging point unit 9, and the processor 27 of the charging point unit 9 transmits this information via the transmitter and receiver unit 25 for wireless transmission and reception to the mobile phone 21 of the driver 19. The app then indicates that the driver 19 can disconnect the charging cable from the selected connection section of the charging point unit 9. The driver 19 disconnects the charging cable from the selected connection section of the charging point unit 9 and drives away from the connection section of the charging point unit 9 with their electric vehicle 13 now fully charged.

[0076] If the check results in a "not OK" status, the processor of the first distribution unit 5 sends the "not OK" status, which may consist of, for example, a "1" (one), to the transmitter and receiver unit of the first distribution unit 5. This unit then transmits the "not OK" status via the electrically conductive cable to the transmitter and receiver unit 31 of the charging point unit 9. The transmitter and receiver unit 31 of the charging point unit 9 then sends the "not OK" status to the processor 27 of the charging point unit 9, which in turn sends the "not OK" status to the transmitter and receiver unit 25 for wireless transmission and reception of the charging point unit 9. The transmitter and receiver unit 25 for wireless transmission and reception of the charging point unit 9 then sends the "not OK" status to the mobile phone 21 and to the app installed on the mobile phone 21, which then displays information indicating that the charging process cannot be started.If the app installed on the mobile phone 21 displays the information that the charging process cannot be started, the driver 19 scans a QR code 23 of the second connection section of the charging point unit 9, and the steps already described are repeated for the second connection section of the charging point unit 9. In particular, since the check for several charging point units can be carried out centrally by the first distribution unit 5, and only very small amounts of data need to be transmitted and processed by each charging point unit 9, the charging point units can be designed very simply, as, for example, low-powered processors and small data storage capacities are sufficient for the charging point units.Furthermore, because the check for multiple charging point units can be performed centrally by the first distribution unit 5, an update of the reference data for multiple charging point units can be carried out at a central location, namely at the first distribution unit 5. The status "OK" and the status "not OK," and in particular the "0" (zero) or "1" (one), can also be referred to as initial data.

[0077] In one embodiment of the method for operating an electric charging network system 1, several electrical energy storage devices of several electric vehicles, wherein each electric vehicle is assigned one of the several electrical energy storage devices, are connected to several connection sections of several charging point units, wherein each connection section of the several connection sections is assigned to a charging point unit 9 of the several charging point units, such that each electrical energy storage device of the several electrical energy storage devices is assigned to one of the connection sections. The first distribution unit 5 records the times at which the electrical energy storage devices are connected to the connection sections.Based on the specified times and their chronological sequence, the corresponding electrical energy is supplied to the charging point units, and the charging processes for the electrical energy storage devices are initiated in this chronological order. This approach is particularly advantageous when more electrical energy is required to charge multiple electrical energy storage devices than can be supplied by the electrical charging network system to the corresponding charging point units within a specific time interval, as the chronological sequence of charging processes allows for efficient charging of the electrical energy storage devices.

[0078] In one embodiment of the method for operating an electric charging network system 1, several electrical energy storage devices of several electric vehicles, wherein each electric vehicle is assigned one of the several electrical energy storage devices, are connected to several connection sections of several charging point units, wherein each connection section of the several connection sections is assigned to a charging point unit 9 of the several charging point units, such that each electrical energy storage device of the several electrical energy storage devices is assigned to one of the connection sections. The first distribution unit 5 records monetary amounts that the drivers of the electric vehicles would be willing to pay to charge the electrical energy storage devices of their electric vehicles.Based on the monetary amounts and their order (when the amounts are arranged in descending order), the corresponding electrical energy is supplied to the charging point units, and the charging processes for the electrical energy storage devices are started in this sequence. This approach is particularly advantageous when more electrical energy is required to charge multiple electrical energy storage devices than can be supplied by the electrical charging network system to the corresponding charging point units within a specific time interval, as the sequence of charging processes allows the electrical energy storage devices to be charged efficiently.

[0079] In one embodiment, the charging point unit 9 is designed to be retractable. For this purpose, the charging point unit 9 has a first section that is inserted into the ground and a second section that can be moved relative to the first section from a retracted position to an extended position and from the extended position to the retracted position by means of a drive unit. When charging begins, if the transmitter and receiver unit 31 of the charging point unit 9 sends the status "OK" to the processor 27 of the charging point unit 9, the processor 27 of the charging point unit 9 sends a control signal to the drive unit, causing the drive unit to move the second section relative to the first section into the extended position, so that the second section protrudes from the ground.The second section includes the connection section of the charging point unit 9 selected by the driver 19, so that the selected connection section of the charging point unit 9 is now accessible to the driver 19. After charging, when the sensor of the charging point unit 9 detects that the charging cable has been removed from the selected connection section of the charging point unit 9, the processor 27 of the charging point unit 9 sends a control signal to the drive unit, causing the drive unit to retract the second section relative to the first section into the retracted position, so that the second section is again recessed into the floor. In another embodiment, the charging point unit 9 can be attached to or mounted on the wall of a parking garage. In yet another embodiment, the charging point unit 9 can be attached to or mounted on the wall of an underground parking garage.

[0080] As previously described, the charging point unit 9 comprises the wireless transmitting and receiving unit 25 and the wireless transmitting and receiving unit 31. The wireless transmitting and receiving unit 25 can also be referred to as the first transmitting and receiving unit of the charging point unit 9, and the wireless transmitting and receiving unit 31 can also be referred to as the second transmitting and receiving unit of the charging point unit 9.

[0081] As already described, Figures 7 to 14 show schematic representations of the fourth embodiment of the electrical charging network system 1 according to the invention. Figure 8 shows a schematic representation of the third distribution unit 11, i.e., the main distributor (HVT), of the electrical charging network system 1; Figure 9 shows a schematic representation of the first distribution unit 5, i.e., the sub-distributor plus (UVT+), of the electrical charging network system 1; Figure 10 shows a schematic representation of a second distribution unit 7, i.e., a sub-distributor (UVT), of the electrical charging network system 1; and Figure 11 shows a schematic representation of a charging point unit 9 of the electrical charging network system 1.

[0082] The third distribution unit 11, i.e., the main distribution unit (MDU), includes a control unit 33, which comprises the third data processing unit already described (comprising the processor and data storage) and the third transmitting and receiving unit already described. Furthermore, the third distribution unit 11, i.e., the main distribution unit (MDU), includes several sensor units of a current measurement system (CMS). Each sensor unit 35 of the current measurement system of the third distribution unit 11 can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the third distribution unit 11 and send a signal representing the detected electric current to the control unit 33. For this purpose, each sensor unit 35 of the current measurement system is connected to the control unit 33 of the third distribution unit 11.Furthermore, the third distribution unit 11, i.e., the main distribution board (MDF), has several electrical connection units. Each of the several electrical connection units 37 has a corresponding sensor unit 35. The third distribution unit 11, i.e., the main distribution board (MDF), has a first electrical connection unit 39, a second electrical connection unit 41, a third electrical connection unit 43, a fourth electrical connection unit 45, and a fifth electrical connection unit 47. The first electrical connection unit 39, the second electrical connection unit 41, the fourth electrical connection unit 45, and the fifth electrical connection unit 47 each have three electrical connections, and the third electrical connection unit 43 has two electrical connections.Furthermore, the third distribution unit 11, i.e., the main distribution board (MDF), has a switching unit 49, which can also be referred to as a power switch module (PSM). The switching unit 49 can selectively connect either the first electrical connection unit 39 or the fifth electrical connection unit 47 to either the second electrical connection unit 41, the third electrical connection unit 43, or the fourth electrical connection unit 45. Preferably, when two specific electrical connection units are connected to each other by means of the switching unit 49, the switching unit 49 ensures that no other connections exist between the electrical connection units.The control unit 33 can send a control signal to the switching unit 49, causing two specific electrical connection units to be connected by the switching unit 49, thus bringing them into a connected state and maintaining that state. The control unit 33 can also send a control signal to the switching unit 49, causing two specific electrical connection units to be disconnected by the switching unit 49, thus bringing them into a disconnected state and maintaining that state. For this purpose, the switching unit 49 is connected to the control unit 33 of the third distribution unit 11. Furthermore, the third distribution unit 11, i.e., the main distribution board (MDF), has a bidirectional inverter 51.The bidirectional inverter 51 can control the energy flow both from the switching unit 49 to the fourth electrical connection unit 45 in a first direction, in which the bidirectional inverter 51 converts alternating voltage, preferably 20 kV, into direct voltage, preferably 0.6 to 1.5 kV, and from the fourth electrical connection unit 45 to the switching unit 49 in a second direction, in which the bidirectional inverter 51 converts direct voltage, preferably 0.6 to 1.5 kV, into alternating voltage, preferably 20 kV.

[0083] The first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), also includes a control unit 33, which comprises the first data processing unit already described (which, as previously described, includes the processor and data storage) and the first transmitting and receiving unit already described. Furthermore, the first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), includes several sensor units of the current measurement system (CMS). Each sensor unit 35 of the current measurement system of the first distribution unit 5 can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the first distribution unit 5 and send a signal representing the detected electric current to the control unit 33.For this purpose, each sensor unit 35 of the current measuring system of the first distribution unit 5 is connected to the control unit 33 of the first distribution unit 5. Furthermore, the first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), has several electrical connection units. Each of the several electrical connection units has a corresponding sensor unit 35. The first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), has a first electrical connection unit 39, a second electrical connection unit 41, a third electrical connection unit 43, and a fourth electrical connection unit 45. The first electrical connection unit 39, the second electrical connection unit 41, and the fourth electrical connection unit 45 each have three electrical connections, and the third electrical connection unit 43 has two electrical connections.Furthermore, the first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), has a switching unit 49, which can also be referred to as a power switch module (PSM). The switching unit 49 can connect the first electrical connection unit 39 and the third electrical connection unit 43. The control unit 33 can send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the third electrical connection unit 43 are connected by the switching unit 49 and kept in a connected state. The control unit 33 can also send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the third electrical connection unit 43 are disconnected by the switching unit 49 and kept in a disconnected state.For this purpose, the switching unit 49 is connected to the control unit 33 of the first distribution unit 5. Furthermore, the first distribution unit 5, i.e., the sub-distribution unit Plus (UVT+), has a bidirectional inverter 51. The bidirectional inverter 51 can control the energy flow both from the first electrical connection unit 39 to the third electrical connection unit 43 in a first direction, in which the bidirectional inverter 51 converts alternating voltage, preferably 20 kV, into direct voltage, preferably 0.6 to 1.5 kV, and from the third electrical connection unit 43 to the first electrical connection unit 39 in a second direction, in which the bidirectional inverter 51 converts direct voltage, preferably 0.6 to 1.5 kV, into alternating voltage, preferably 20 kV. Furthermore, the first distribution unit 5, i.e., the sub-distribution unit Plus, has...

[0084] (UVT+), a switching unit 49, which can also be referred to as another switching unit.

[0085] The switching unit 49 can selectively connect the first electrical connection unit 39 either to the second electrical connection unit 41 or to the fourth electrical connection unit 45. Preferably, when the first electrical connection unit 39 is connected to the second electrical connection unit 41 by means of the switching unit 49, the switching unit 49 ensures that there is no connection between the first electrical connection unit 39 and the fourth electrical connection unit 45. Preferably, when the first electrical connection unit 39 is connected to the fourth electrical connection unit 45 by means of the switching unit 49, the switching unit 49 ensures that there is no connection between the first electrical connection unit 39 and the second electrical connection unit 41.The control unit 33 can send a control signal to the switching unit 49, so that either the first electrical connection unit 39 is connected to the second electrical connection unit 41 using the switching unit 49, or the first electrical connection unit 39 is connected to the fourth electrical connection unit 45 using the switching unit 49, so that either the first electrical connection unit 39 and the second electrical connection unit 41 or the first electrical connection unit 39 and the fourth electrical connection unit 45 are brought into a connected state and kept in this state.Furthermore, the control unit 33 can send a control signal to the switching unit 49, so that either the first electrical connection unit 39 and the second electrical connection unit 41 are disconnected from each other by means of the switching unit 49, or the first electrical connection unit 39 and the fourth electrical connection unit 45 are disconnected from each other by means of the switching unit 49, so that either the first electrical connection unit 39 and the second electrical connection unit 41 or the first electrical connection unit 39 and the fourth electrical connection unit 45 are brought into a separated state and kept in this state. For this purpose, the switching unit 49 is connected to the control unit 33 of the third distribution unit 11.

[0086] Each second distribution unit 7 shown in Figure 7, i.e., each sub-distribution unit (SDU), can be constructed like the second distribution unit 7 shown in Figure 10. Preferably, all second distribution units are constructed identically. The second distribution unit 7, i.e., the sub-distribution unit (SDU), also includes a control unit 33, which comprises the second data processing unit already described (which, as already described, includes the processor and the data memory) and the second transmitting and receiving unit already described. Furthermore, the second distribution unit 7, i.e., the sub-distribution unit (SDU), includes several sensor units of the current measurement system (CMS).Each sensor unit 35 of the current measurement system of the second distribution unit 7 can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the second distribution unit 7 and send a signal representing the detected electric current to the control unit 33. For this purpose, each sensor unit 35 of the current measurement system of the second distribution unit 7 is connected to the control unit 33 of the second distribution unit 7. Furthermore, the second distribution unit 7, i.e., the sub-distribution board (SDB), has several electrical connection units. Each electrical connection unit 37 has a corresponding sensor unit 35.The second distribution unit 7, i.e., the sub-distribution board (SDB), has a first electrical connection unit 39, a second electrical connection unit 41, a third electrical connection unit 43, a fourth electrical connection unit 45, and a fifth electrical connection unit 47. The first electrical connection unit 39, the third electrical connection unit 43, and the fifth electrical connection unit 47 each have three electrical connections, the second electrical connection unit 41 has four electrical connections, and the fourth electrical connection unit 45 has two electrical connections. Furthermore, the second distribution unit 7, i.e., the sub-distribution board (SDB), has a switching unit 49, which can also be referred to as a power switch module (PSM). The switching unit 49 can connect the first electrical connection unit 39 and the fourth electrical connection unit 45.The control unit 33 can send a control signal to the switching unit 49, causing the first electrical connection unit 39 and the fourth electrical connection unit 45 to be connected by the switching unit 49, thus bringing them into a connected state and maintaining that state. The control unit 33 can also send a control signal to the switching unit 49, causing the first electrical connection unit 39 and the fourth electrical connection unit 45 to be disconnected by the switching unit 49, thus bringing them into a disconnected state and maintaining that state. For this purpose, the switching unit 49 is connected to the control unit 33 of the second distribution unit 7. Furthermore, the second distribution unit 7, i.e., the sub-distribution board (SDB), has a bidirectional inverter 51.The bidirectional inverter 51 can control the energy flow both from the first electrical connection unit 39 to the fourth electrical connection unit 45 in a first direction, in which the bidirectional inverter 51 converts alternating voltage, preferably 20 kV, into direct voltage, preferably 0.6 to 1.5 kV, and from the fourth electrical connection unit 45 to the first electrical connection unit 39 in a second direction, in which the bidirectional inverter 51 converts direct voltage, preferably 0.6 to 1.5 kV, into alternating voltage, preferably 20 kV. Furthermore, the second distribution unit 7, i.e., the sub-distribution board (SDB), includes a transformer 53, which can also be referred to as a three-phase AC transformer, three-phase transformer, or three-phase transformer.The transformer 53 is connected to both the first electrical connection unit 39 and the second electrical connection unit 41.

[0087] Each charging point unit 9 shown in Figure 7 can be constructed in the same way as the charging point unit 9 shown in Figure 11. Preferably, all charging point units are constructed identically. The charging point unit 9 has a sensor unit 35 of the current measurement system (CMS). The sensor unit 35 of the current measurement system of the charging point unit 9 can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the charging point unit 9 and send a signal representing the detected electric current to the control unit 33 of a second distribution unit 7, which is assigned to the corresponding charging point unit 9. For this purpose, the sensor unit 35 of the current measurement system of the charging point unit 9 is connected to the control unit 33 of the second distribution unit 7. The charging point unit 9 also has an electrical connection unit 37.The electrical connection unit 37 includes a corresponding sensor unit 35. The electrical connection unit 37 can also be referred to as the first electrical connection unit 39 of the charging point unit 9. The first electrical connection unit 39 has four electrical connections. Furthermore, the charging point unit 9 includes a switching unit 49, which can also be referred to as a power switch module (PSM).The switching unit 49 can optionally connect either the first electrical connection unit 39 and a first electrical connection section 55 of the charging point unit 9, which can be referred to as a connection section of the charging point unit 9, or the first electrical connection unit 39 and a second electrical connection section 57 of the charging point unit 9, which can also be referred to as a connection section of the charging point unit 9, or the first electrical connection unit 39 to both the first electrical connection section 55 of the charging point unit 9 and the second electrical connection section 57 of the charging point unit 9. An electrical energy storage device of an electric vehicle 13 can be connected to the first electrical connection section 55 of the charging point unit 9, so that the electrical energy storage device of the electric vehicle 13 can be charged with electrical energy.Similarly, the second electrical connection section 57 of the charging point unit 9 can also be used to connect an electrical energy storage device of an electric vehicle 13, so that the electrical energy storage device of the electric vehicle 13 can be charged with electrical energy. Thus, the charging point unit 9 can charge two electrical energy storage devices, where the first electrical energy storage device can be an electrical energy storage device of a first electric vehicle and the second electrical energy storage device can be an electrical energy storage device of a second electric vehicle.The control unit 33 of the second distribution unit 7 can send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the first electrical connection section 55 of the charging point unit 9 are connected to each other by means of the switching unit 49, so that they are brought into a connected state and held in this state. Furthermore, the control unit 33 of the second distribution unit 7 can send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the first electrical connection section 55 of the charging point unit 9 are disconnected from each other by means of the switching unit 49, so that they are brought into a disconnected state and held in this state.Similarly, the control unit 33 of the second distribution unit 7 can send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the second electrical connection section 57 of the charging point unit 9 are connected to each other by means of the switching unit 49, thus bringing them into a connected state and keeping them in that state. Furthermore, the control unit 33 of the second distribution unit 7 can send a control signal to the switching unit 49, so that the first electrical connection unit 39 and the second electrical connection section 57 of the charging point unit 9 are disconnected from each other by means of the switching unit 49, thus bringing them into a disconnected state and keeping them in that state. For this purpose, the switching unit 49 of the charging point unit 9 is connected to the control unit 33 of the second distribution unit 7.

[0088] Furthermore, the charging point unit 9 has several sensor modules. Each sensor module 59 can also be referred to as an IoT (Internet of Things, IoT) sensor module.

[0089] The charging point unit 9 includes an ultrasonic sensor, also known as an ultrasonic receiver; a third sensor module has a radar sensor; and a fourth sensor module has a 3D camera. Additional sensor modules may include, for example, a camera, a microphone, parking space monitoring, and / or other sensors. Each sensor module is designed to be connected to a section of the charging point unit 9 in a modular manner, so that the corresponding sensor module forms a section of the charging point unit 9. Each sensor module can therefore be understood as a module that can be added to and removed from the charging point unit 9 at will, with the full functionality of the charging point unit still being guaranteed for the other modules of the charging point unit 9, regardless of whether a further module is added or removed.Because each sensor module is designed to be connected in a modular manner to a section of its assigned charging point unit 9, an expansion of the functionality of each charging point unit 9 is ensured.

[0090] Furthermore, the charging point unit 9 has an interface 61, which can also be referred to as a sensor interface or sensor I / O interface. The interface 61 is connected to each sensor module 59. When a sensor module 59 detects a specific property, such as a physical or chemical property in its environment, and sends a signal representing this property to the interface 61, the interface 61 can forward this signal to the control unit 33 of the second distribution unit 7. For this purpose, the interface 61 is connected to the control unit 33 of the second distribution unit 7.

[0091] Furthermore, the charging point unit 9 has a user interface 63, which can also be referred to as a user interface, human-machine interface, MMS, or HMI. A driver 19 of an electric vehicle 13 can input commands via the user interface 63. For example, a user input could be that the driver wants to start or stop a charging process. The charging point unit 9 also has an RFID (radio-frequency identification) reader 65, which can also be referred to as an RFID reader. Using the RFID reader 65, an identifying code stored on a transponder can be read. For example, a driver 19 can identify themselves using the identifying code.The charging point unit 9 shown in Figure 11 is provided with two RFID (radio-frequency identification) readers, a first RFID (radio-frequency identification) reader for the first electrical connection section 55 and a second RFID (radio-frequency identification) reader for the second electrical connection section 57.

Figure 12 shows three fast charging units, three of which are shown in Figure 6 and four in Figure 7. The fast charging unit 67 shown on the left in Figure 12 shows a schematic diagram of a megawatt charging unit 69, which can also be referred to as a megawatt charging station and is constructed according to a megawatt charging system standard. The fast charging unit 67 shown in the center of Figure 12 shows a schematic diagram of a first fast charging point unit 71, which can also be referred to as a fast charger.The fast charging unit 67 shown on the right in Figure 12 illustrates a schematic diagram of a second fast charging point unit 73, which can also be referred to as a fast charger. Each fast charging unit 67 has a sensor unit 35 of the current measurement system (CMS). The sensor unit 35 of the current measurement system of the fast charging unit 67 can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the fast charging unit 67 and send a signal representing the detected electric current to a corresponding control unit 33 assigned to the respective fast charging unit 67. In the case of the megawatt charging unit 69, this is the control unit 33 of the third distribution unit 11, i.e., the main distribution board (MDB), which has already been described.For the first fast-charging point unit 71, this is either the control unit 33 already described, belonging to one of the first distribution units 5 assigned to the first fast-charging point unit 71, i.e., the sub-distributor Plus (UVT+), or the control unit 33 already described, belonging to one of the second distribution units 7 assigned to the first fast-charging point unit 71, i.e., a sub-distributor (UVT). For the second fast-charging point unit 73, this is the control unit 33 already described, belonging to one of the second distribution units 7 assigned to the second fast-charging point unit 73, i.e., a sub-distributor (UVT). For this purpose, the sensor unit 35 of the current measuring system of the corresponding fast-charging unit 67 is connected to the corresponding control unit 33. Furthermore, each fast-charging unit 67 has an electrical connection unit 37. The electrical connection unit 37 has a corresponding sensor unit 35.The electrical connection unit 37 can also be referred to as the first electrical connection unit 39 of the corresponding fast-charging unit 67. In the megawatt charging unit 69 and the first fast-charging point unit 71, the first electrical connection unit 39 has three electrical connections.

The switching unit 49 can connect the first electrical connection unit 39 to an electrical connection section of the corresponding fast-charging unit 67, which can also be referred to as the first electrical connection section 55 or connection section.The first electrical connection section 55 of the corresponding charging unit 67 can be used to connect an electrical energy storage device of an electric vehicle 13, so that the electrical energy storage device of the electric vehicle 13 can be charged with electrical energy. A corresponding control unit 33 can send a control signal to the corresponding switching unit 49, so that the first electrical connection unit 39 and the first electrical connection section 55 are connected to each other by means of the switching unit 49, so that they are brought into a connected state and kept in this state.Furthermore, the corresponding control unit 33 can send a control signal to the corresponding switching unit 49, so that the first electrical connection unit 39 and the first electrical connection section 55 are disconnected from each other by means of the switching unit 49, thus bringing them into a separated state and keeping them in this state. For this purpose, the corresponding switching unit 49 is connected to the corresponding control unit 33. Each charging unit 67 also has a user interface 63, which can also be referred to as a user interface, human-machine interface, MMS, or HMI. A driver 19 of an electric vehicle 13 can make a user input via the user interface 63. A user input could be, for example, that the driver wants to start or stop a charging process.Furthermore, each cutting charging unit 67 has an RFID (radio-frequency identification) reader 65, which can also be referred to as an RFID reader. Using the RFID reader 65, an identifying code stored on a transponder can be read. For example, a driver 19 can identify themselves using the identifying code. Figure 13 shows two storage units, three of which are shown in Figure 7 and one or more of which may also be provided in Figure 6. Each storage unit 75 has an energy storage device that can store energy in the form of electrical energy. Each storage unit 75 can also be referred to as a megawatt storage unit or megawatt (MW) storage or large-scale storage.Each storage unit 75 has a management system, in particular a battery management system 77 (BMS), which can, for example, detect the state of charge of the energy storage device and send a signal representing the detected state of charge to a corresponding control unit 33, for example, to a control unit 33 of the third distribution unit 11, i.e., the main distribution board (MDB), to a control unit 33 of the first distribution unit 5, i.e., the sub-distribution board plus (SDB+), or to a control unit 33 of a second distribution unit 7, i.e., a sub-distribution board (SDB). For this purpose, the corresponding battery management system 77 is connected to the corresponding control unit 33. Each storage unit 75 has an electrical connection unit 37 that is connected to the energy storage device of the corresponding storage unit 75.The energy storage unit can be charged and discharged via each electrical connection unit 37. The storage unit 75 shown on the left in Figure 13 has a first electrical connection unit 39. The storage unit 75 shown on the right in Figure 13 has a first electrical connection unit 39 and a second electrical connection unit 41. Each first electrical connection unit 39 has two electrical connections, and the second electrical connection unit 41 also has two electrical connections.

[0093] Figure 14 shows two components of the fourth voltage level, which are also depicted in Figure 6 and Figure 7. In Figure 14, a renewable energy conversion device 79, such as a solar park, is shown on the left, and a power grid 81 is shown on the right. Each component 17 of the fourth voltage level has a sensor unit 35 of the current measurement system (CMS). The sensor unit 35 of the current measurement system of the component 17 of the fourth voltage level can detect the electric current, in particular an electric current intensity and / or an electric voltage, at a predetermined section of the component 17 of the fourth voltage level and send a signal representing the detected electric current to the control unit 33 of the third distribution unit 11.For this purpose, the sensor unit 35 of the current measuring system of the corresponding component 17 of the fourth voltage level is connected to the control unit 33 of the third distribution unit 11. Furthermore, each component 17 of the fourth voltage level has an electrical connection unit 37. The electrical connection unit 37 has a corresponding sensor unit 35. The electrical connection unit 37 can also be referred to as the first electrical connection unit 39 of the corresponding component 17 of the fourth voltage level. The first electrical connection unit 39 has three electrical connections.

[0094] The first electrical connection unit 39 of the renewable energy conversion facility 79, such as the solar park, is connected to the first electrical connection unit 39 of the third distribution unit 11, i.e., the main distribution board (MDB), and the first electrical connection unit 39 of the power grid 81 is connected to the fifth electrical connection unit 47 of the third distribution unit 11, i.e., the MDB.

[0095] Distribution unit 11 is thus connected to a component 17 of the fourth voltage level such that the third distribution unit 11 can be supplied with electrical energy at a voltage on the fourth voltage level. Using the switching unit 49 of the third distribution unit 11, it can be selected whether the third distribution unit 11 is supplied with electrical energy by means of the renewable energy conversion device 79, such as the solar park, or by means of the power grid 81. The second electrical connection unit 41 of the third distribution unit 11, i.e., the main distribution board (HVT), is connected to the first electrical connection unit 39 of the first distribution unit 5, i.e., the sub-distribution board (UVT+), so that the first distribution unit 5 can be supplied with electrical energy at a voltage on the first voltage level.For this purpose, the switching unit 49 of the third distribution unit 11 can, for example, connect either the first electrical connection unit 39 of the third distribution unit 11 with the second electrical connection unit 41 of the third distribution unit 11, or the fifth electrical connection unit 47 of the third distribution unit 11 with the second electrical connection unit 41 of the third distribution unit 11. The third electrical connection unit 43 of the third distribution unit 11, i.e., of the main distribution board, is connected to the first electrical connection unit 39 of the storage unit 75 assigned to the third distribution unit 11, so that the storage unit 75 can be supplied with electrical energy and thus charged.For this purpose, the switching unit 49 of the third distribution unit 11 can, for example, connect the first electrical connection unit 39 of the third distribution unit 11 to the bidirectional inverter 51, or the fifth electrical connection unit 47 of the third distribution unit 11 to the bidirectional inverter 51. Furthermore, the fourth electrical connection unit 45 of the third distribution unit 11, i.e., of the main distribution board (MDF), is connected to the first electrical connection unit 39 of the megawatt charging unit 69, so that the megawatt charging unit 69 can be supplied with electrical energy, enabling the energy storage device of an electric vehicle 13 to be charged using the megawatt charging unit 69.For this purpose, the switching unit 49 of the third distribution unit 11 can, for example, either connect the first electrical connection unit 39 of the third distribution unit 11 with the fourth electrical connection unit 45 of the third distribution unit 11 or the fifth electrical connection unit 47 of the third distribution unit 11 with the fourth electrical connection unit 45 of the third distribution unit 11.

[0096] As previously described, the second electrical connection unit 41 of the third distribution unit 11, i.e., the main distribution board (HVT), is connected to the first electrical connection unit 39 of the first distribution unit 5, i.e., the sub-distribution board (UVT+), so that the first distribution unit 5 can be supplied with electrical energy at a voltage on the first voltage level. The second electrical connection unit 41 of the first distribution unit 5, i.e., the sub-distribution board (UVT+), is connected to the first electrical connection unit 39 of every second distribution unit 7, i.e., every sub-distribution board (UVT), so that every second distribution unit 7 can be supplied with electrical energy at a voltage on the second voltage level. For this purpose, the switching unit 49 of the first distribution unit 5, shown above in Figure 9, can connect the first electrical connection unit 39 of the first distribution unit 5 to the second electrical connection unit 41 of the first distribution unit 5.The third electrical connection unit 43 of the first distribution unit 5, i.e., of the UVT+, is connected to the first electrical connection unit 39 of the storage unit 75 assigned to the first distribution unit 5, so that the storage unit 75 can be supplied with electrical energy and thus charged. For this purpose, the switching unit 49 of the first distribution unit 5, shown below in Figure 9, can, for example, connect the first electrical connection unit 39 of the first distribution unit 5 to the third electrical connection unit 43 of the first distribution unit 5 via the bidirectional inverter 51.Furthermore, the fourth electrical connection unit 45 of the first distribution unit 5, i.e., of the UVT+, is connected to the first electrical connection unit 39 of a first fast-charging point unit 71 assigned to the first distribution unit 5, so that the first fast-charging point unit 71 can be supplied with electrical energy, enabling the energy storage device of an electric vehicle 13 to be charged using the first fast-charging point unit 71. For this purpose, the switching unit 49 of the first distribution unit 5, shown above in Figure 9, can, for example, connect the first electrical connection unit 39 of the first distribution unit 5 to the fourth electrical connection unit 45 of the first distribution unit 5.

[0097] As previously described, the second electrical connection unit 41 of the first distribution unit 5, i.e., of the UVT+, is connected to the first electrical connection unit 39 of every second distribution unit 7, i.e., of each UVT, so that every second distribution unit 7 can be supplied with electrical energy at a voltage on the second voltage level. The second electrical connection unit 41 of every second distribution unit 7, i.e., of each UVT, is connected to the first electrical connection unit 39 of each charging point unit 9 assigned to the corresponding second distribution unit 7, so that each charging point unit 9 can be supplied with electrical energy at a voltage on the third voltage level.For this purpose, the transformer 53 of the corresponding second distribution unit 7 connects the first electrical connection unit 39 of the corresponding second distribution unit 7 to the second electrical connection unit 41 of the corresponding second distribution unit 7. The third electrical connection unit 43 of each second distribution unit 7, i.e., of each UVT, is connected to the first electrical connection unit 39 of the storage unit 75 assigned to the corresponding second distribution unit 7, so that the storage unit 75 can be supplied with electrical energy and thus charged. For this purpose, a switching unit of the second distribution unit 7 (not shown in Figure 10) can, for example, connect the first electrical connection unit 39 of the second distribution unit 7 to the third electrical connection unit 43 of the second distribution unit 7 via a bidirectional inverter (not shown in Figure 10).Preferably, the bidirectional inverter is arranged between the third electrical connection unit 43 of the second distribution unit 7 and the first electrical connection unit 39 of the storage unit 75 and is connected to both the third electrical connection unit 43 of the second distribution unit 7 and the first electrical connection unit 39 of the storage unit 75.The bidirectional inverter can control the energy flow both from the third electrical connection unit 43 of the second distribution unit 7 to the first electrical connection unit 39 of the storage unit 75 in a first direction, in which the bidirectional inverter converts alternating voltage, preferably 0.4 kV, into direct voltage, preferably 0.6 to 1.5 kV, and from the first electrical connection unit 39 of the storage unit 75 to the third electrical connection unit 43 of the second distribution unit 7 in a second direction, in which the bidirectional inverter 51 converts direct voltage, preferably 0.6 to 1.5 kV, into alternating voltage, preferably 0.4 kV.The fourth electrical connection unit 45 of each second distribution unit 7, i.e., each UVT, is connected to the second electrical connection unit 41 of the storage unit 75 assigned to the corresponding second distribution unit 7, so that the storage unit 75 can be supplied with electrical energy and thus charged. For this purpose, the switching unit 49 of the second distribution unit 7 can, for example, connect the first electrical connection unit 39 of the second distribution unit 7 to the fourth electrical connection unit 45 of the second distribution unit 7 via the bidirectional inverter 51. The storage unit 75 assigned to the corresponding second distribution unit 7 can therefore be supplied with electrical energy and thus charged via both the third electrical connection unit 43 of the second distribution unit 7 and the fourth electrical connection unit 45 of the second distribution unit 7.Furthermore, the storage unit 75 assigned to the corresponding second distribution unit 7 can feed electrical energy back into the rest of the electrical charging network system via both the third electrical connection unit 43 of the second distribution unit 7 and the fourth electrical connection unit 45 of the second distribution unit 7, preferably optionally either to a second voltage level, preferably to a medium voltage level, preferably with an alternating voltage at the medium voltage level of 20 kV, or to a third voltage level, preferably to a low voltage level, preferably with an alternating voltage at the

[0098] Low-voltage level of 0.4 kV. This is particularly advantageous for bidirectional energy flow. In particular, a bidirectional transformer, which would have to ensure conversion from the third voltage level, preferably from the low-voltage level, preferably with an alternating voltage at the low-voltage level of 0.4 kV, to the second voltage level, preferably to the medium-voltage level, preferably with an alternating voltage at the medium-voltage level of 20 kV, can be dispensed with.Furthermore, with the help of the storage unit 75 and the connection of the storage unit 75 via the bidirectional inverters to both the second voltage level and the third voltage level, not only can a bidirectional transformer be dispensed with, which must ensure a conversion both from the second voltage level to the third voltage level and from the third voltage level to the second voltage level, but this configuration is also advantageous for grid stability, since the energy flows in the electrical charging network system 1 are thus better controllable.Furthermore, the fifth electrical connection unit 47 of each second distribution unit 7, i.e., each UVT, is connected to the first electrical connection unit 39 of a first fast-charging point unit 71 assigned to the corresponding second distribution unit 7, so that the first fast-charging point unit 71 can be supplied with electrical energy, enabling the energy storage device of an electric vehicle 13 to be charged using the first fast-charging point unit 71. For this purpose, a switching unit of the second distribution unit 7 (not shown in Figure 10) can, for example, connect the first electrical connection unit 39 of the second distribution unit 7 to the fifth electrical connection unit 47 of the second distribution unit 7.

[0099] As already described, the second electrical connection unit 41 of each second distribution unit 7, i.e., each UVT, is connected to the first electrical connection unit 39 of each charging point unit 9 assigned to the corresponding second distribution unit 7, so that each charging point unit 9 can be supplied with electrical energy at an electrical voltage on the third voltage level. Thus, an energy storage device of an electric vehicle 13 can be charged using each charging point unit 9.

[0100] Each component of a fourth voltage level 17, i.e., in the case of the electrical charging network system shown in Figure 7, the renewable energy conversion device 79, such as the solar park, and the power grid 81, is connected to the third distribution unit 11 in such a way that data can be transmitted between each component of the fourth voltage level 17 and the third distribution unit 11. A fiber optic cable is provided between each component of the fourth voltage level 17 and the third distribution unit 11 for data transmission. Furthermore, each component of the fourth voltage level 17 has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between each component of the fourth voltage level 17 and the third distribution unit 11.Each first connection section 83 is a section of the corresponding sensor unit 35 or is connected to the corresponding sensor unit 35.

The first connection section 83 is a section of the control unit 33 of the first distribution unit 5 or can be connected to the control unit 33 of the first distribution unit 5.

[0102] The first distribution unit 5, i.e., the UVT+, is connected to every second distribution unit 7, i.e., to every UVT, in such a way that data can be transmitted between the first distribution unit 5 and every second distribution unit 7. A suitable fiber optic cable is provided between the first distribution unit 5 and every second distribution unit 7 for data transmission. Furthermore, the first distribution unit 5 has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between the first distribution unit 5 and the second distribution unit 7. The first connection section 83 is a section of the control unit 33 of the first distribution unit 5 or can be connected to the control unit 33 of the first distribution unit 5.Every second distribution unit 7 also has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between the first distribution unit 5 and the second distribution unit 7. The first connection section 83 is a section of the control unit 33 of the corresponding second distribution unit 7 or can be connected to the control unit 33 of the corresponding second distribution unit 7.

[0103] Every second distribution unit 7, i.e., every UVT, is connected to each of its assigned charging point units 9 in such a way that data can be transmitted between the corresponding second distribution unit 7 and the corresponding charging point unit 9. A suitable cable is provided between the corresponding second distribution unit 7 and each of its assigned charging point units 9 for data transmission, via which data transmission is ensured using powerline communication. In the embodiment of the electric charging network system 1 shown in Figure 7, three such cables are provided between the corresponding second distribution unit 7 and each of its assigned charging point units 9 for data transmission, via which data transmission is ensured using powerline communication.Furthermore, every second distribution unit 7 has a first connection section 83 to which the cable can be attached and through which data can be transmitted between the corresponding second distribution unit 7 and each charging point unit 9 associated with it. In the embodiment of the electric charging network system 1 shown in Figure 7, there are three such first connection sections. Each first connection section 83 is a section of the control unit 33 of the second distribution unit 7 or can be connected to the control unit 33 of the second distribution unit 7. Each charging point unit 9 also has a first connection section 83 to which the cable can be attached and through which data can be transmitted between the second distribution unit 7 and the charging point unit 9.

Furthermore, every second distribution unit 7, i.e., every UVT, is connected to its assigned first fast-charging point unit 71 in such a way that data can be transmitted between the corresponding second distribution unit 7 and the first fast-charging point unit 71. A cable is provided between the second distribution unit 7 and the first fast-charging point unit 71 for data transmission, via which data transmission is ensured using powerline communication.In the embodiment of the electric charging network system 1 shown in Figure 7, two cables are provided between the corresponding second distribution unit 7 and the first fast-charging point unit 71 for data transmission, via which data transmission is ensured using powerline communication. The second distribution unit 7 also has a first connection section (not shown in Figure 10) to which the cable can be attached and through which data can be transmitted between the second distribution unit 7 and the first fast-charging point unit 71.

[0107] Every second distribution unit 7, i.e., every UVT, is connected to each of its associated second fast-charging point units 73 in such a way that data can be transmitted between the respective second distribution unit 7 and the corresponding second fast-charging point unit 73. A suitable cable is provided between the respective second distribution unit 7 and each of its associated second fast-charging point units 73 for data transmission, via which data transmission is ensured using powerline communication. In the embodiment of the electrical charging network system 1 shown in Figure 7, two such cables are provided between the respective second distribution unit 7 and each of its associated second fast-charging point units 73 for data transmission, via which data transmission is ensured using powerline communication.Furthermore, every second distribution unit 7 has a first connection section 83 to which the cable can be attached and via which data can be transmitted between the corresponding second distribution unit 7 and each associated second fast-charging point unit 73. In the embodiment of the electric charging network system 1 shown in Figure 7, these are two first connection sections, via which the charging point units are already connected to the second distribution unit 7. Each first connection section 83 is a section of the control unit 33 of the second distribution unit 7 or can be connected to the control unit 33 of the second distribution unit 7. Each second fast-charging point unit 73 also has a first connection section 83 to which the cable can be attached and via which data can be transmitted between the second distribution unit 7 and the second fast-charging point unit 73.In the embodiment of the electric charging network system 1 shown in Figure 7, these are two first connection sections.

Furthermore, every second distribution unit 7, i.e., every UVT, is connected to its associated storage unit 75 in such a way that data can be transferred between the second distribution unit 7 and the storage unit 75. A fiber optic cable is provided between the second distribution unit 7 and the storage unit 75 for data transmission.

The storage unit 75 also has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between the first distribution unit 5 and the storage unit 75. The first connection section 83 is a section of the battery management system 77 of the storage unit 75 or can be connected to the battery management system 77 of the storage unit 75.

[0108] Furthermore, each component of the fourth voltage level 17, i.e., in the case of the electrical charging network system shown in Figure 7, the renewable energy conversion device 79, such as the solar park, and the power grid 81, is connected to the first distribution unit 5, i.e., to the UVT+, in such a way that data can be transmitted between each component of the fourth voltage level 17 and the first distribution unit 5. A cable, in particular a fiber optic cable, is provided between each component of the fourth voltage level 17 and the first distribution unit 5 for data transmission. In addition, each component of the fourth voltage level 17 has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between each component of the fourth voltage level 17 and the first distribution unit 5.The first distribution unit 5 also has a first connection section 83 to which the fiber optic cable can be attached and through which data can be transmitted between each component of the fourth voltage level 17 and the third distribution unit 11. In the embodiment of the electrical charging network system 1 shown in Figure 7, there are two such first connection sections. Each first connection section 83 is a section of the control unit 33 of the first distribution unit 5 or can be connected to the control unit 33 of the first distribution unit 5.

[0109] In addition to the connections already described between the individual components of the electric charging network system 1, in order to ensure data transmission between the individual components of the electric charging network system 1, for which the first connection sections already described are provided in particular, the third distribution unit 11, i.e., the HVT, the first distribution unit 5, i.e., the UVT+, every second distribution unit 7, i.e., the UVT, every charging point unit 9, and every fast-charging unit 67 have a second connection section 85. In the embodiment of the electric charging network system 1 shown in Figure 7, there are two second connection sections for each of the listed components of the electric charging network system 1.Using the second connection sections, the third distribution unit 11 (HVT), the first distribution unit 5 (UVT+), every second distribution unit 7 (UVT), every charging point unit 9, and every fast-charging unit 67 can be connected to a data transmission network, such as the internet, which differs from the data transmission options described in connection with the first connection sections. The data transmission options described in connection with the first connection sections are ensured by connections between the individual components of the electric charging network system 1. These different...

[0110] Connections between the individual components of the electric charging network system 1 can also be referred to as the first data network or private data network. The data transmission options described in connection with the second connection sections are ensured, for example, by connections between the individual components of the electric charging network system 1 and other components that are not part of the electric charging network system 1. These various connections between the individual components of the electric charging network system 1 and other components can also be referred to as the second data network or public data network.

[0111] The electric charging network system 1 thus has an independent energy and data infrastructure decoupled from the public power grid. This infrastructure, which can be operated as an independent network—also referred to as an internal network—from the third distribution unit 11 (the main distribution board) towards the charging point units 9, can be viewed from this perspective. This independent network supplies all downstream system components, such as each first distribution unit 5 (UVT+), each second distribution unit 7 (UVT), each charging point unit 9, each fast charging unit 67, and each storage unit 75, independently of the public power grid.Because the electric charging network system 1 has an independent energy and data infrastructure decoupled from the public power grid, it can be used, for example, for military applications, in the expansion of disaster relief measures, or for civilian purposes. For instance, the electric charging network system 1 can supply a region if the public power grid collapses. This independent energy and data infrastructure ensures that the electric charging network system can form a basis for municipal resilience and urban security. The electric charging network system 1 is therefore designed for diverse applications and can thus also be described as a multi-use charging network system.

[0112] Preferably, a transfer station is provided between each component 17 of the fourth voltage level and the third distribution unit 11, or each component 17 of the fourth voltage level has a transfer station. Figure 14 shows a section of the transfer station, namely the sensor unit 35. The transfer station can also be referred to as the grid transfer point. The grid transfer point can preferably supply up to 2750 charging point units with electrical energy. The electrical charging network system 1 is preferably configured to tap electrical energy directly at a grid transfer point or directly at several grid transfer points. The electrical charging network system 1 represents a comprehensive ecosystem for a modern e-charging infrastructure, preferably from the grid transfer point to each of the multiple charging point units.Each grid connection point is preferably provided either by the regional electricity producer or by a supra-regional grid operator. If multiple grid connection points are planned, one or more can be provided by the regional electricity producer, and one or more can be provided by a supra-regional grid operator. Thus, the electrical charging network system 1 can, for example, utilize regionally generated electricity, supra-regional electricity, or both. The third distribution unit 11, the main distribution board (MDF), is connected to the grid connection points.Preferably, several components of the fourth voltage level are provided, and thus also several grid connection points, wherein a corresponding grid connection point is provided for each component of the fourth voltage level 17, which is connected to the third distribution unit 11. The third distribution unit 11, i.e., the main distribution board (MDB), is connected to each of the multiple grid connection points. The third distribution unit 11, i.e., the main distribution board (MDB), preferably has a capacity of up to 2750 charging points, preferably with 22 kW each, so that the third distribution unit 11, i.e., the main distribution board (MDB), can preferably supply up to 2750 charging point units, preferably with 22 kW each, with electrical energy.

[0113] Preferably, the third distribution unit 11, i.e., the main distribution board (MDF), is configured for bidirectional charging. The third distribution unit 11, i.e., the main distribution board (MDF), is thus configured to feed electrical energy from the electrical energy storage devices of electric vehicles, each of which is connected to a corresponding charging point unit 9 and is configured for bidirectional charging, back into the electrical charging network system 1 as needed, via the corresponding first distribution unit 5, i.e., the corresponding sub-distribution board plus (SDB+), the corresponding second distribution unit 7, i.e., the corresponding sub-distribution board (SDB), and the corresponding charging point unit 9, to which the corresponding electric vehicle 13 is connected.For each electric vehicle 13, from whose electrical energy storage system electrical energy is to be fed back into the power grid, a corresponding path is provided within the electric charging network system 1, which connects the third distribution unit 11, i.e., the main distribution board (MDF), with the charging point unit 9 to which the corresponding electric vehicle 13 is connected. This path runs along the corresponding first distribution unit 5, i.e., the corresponding sub-distribution board plus (SDB+), and along the corresponding second distribution unit 7, i.e., the corresponding sub-distribution board (SDB). Each first distribution unit 5, i.e., each sub-distribution board plus (SDB+), is connected to the third distribution unit 11. Preferably, each first distribution unit 5, i.e., each sub-distribution board plus (SDB+), is directly connected to the third distribution unit 11.Alternatively, preferably, a first distribution unit 5, i.e., a sub-distribution unit plus (UVT+), is directly connected to the third distribution unit 11. This first distribution unit 5 can also be referred to as the master. Preferably, the other first distribution units are connected to the third distribution unit 11 via the first distribution unit 5 already described, i.e., indirectly via the master. The first distribution units connected to the third distribution unit 11 via the master can also be referred to as slaves.

[0114] Particularly when several first distribution units are provided, each first distribution unit 5, i.e., each sub-distributor plus (UVT+), of the electrical charging network system 1 is preferably designed to be connected to the third distribution unit 11 in a modular manner. Each first distribution unit 5, i.e., each sub-distributor plus (UVT+), of the electrical charging network system 1 can therefore be understood as a module that can be added to and removed from the electrical charging network system 1 as needed, whereby the full functionality of the electrical charging network system 1 is still guaranteed for the other modules provided in the electrical charging network system 1 with each additional module added and each additional module removed.By ensuring that each first distribution unit 5, i.e., each sub-distribution unit plus (UVT+), of the electrical charging network system 1 is designed to be connected to the third distribution unit 11 in a modular manner, the scalability of the electrical charging network system 1 is guaranteed. Preferably, at least one first distribution unit 5, i.e., a sub-distribution unit plus (UVT+), is provided.

[0115] Likewise, every second distribution unit 7, i.e., every sub-distribution board (SDB), of the electrical charging network system 1 is designed to be connected in a modular manner to the first distribution unit 5, to which the corresponding second distribution unit 7 is assigned. Each second distribution unit 7, i.e., every sub-distribution board (SDB), of the electrical charging network system 1 can therefore be understood as a module that can be added to and removed from the electrical charging network system 1 as needed, whereby the full functionality of the electrical charging network system 1 is still guaranteed for the other modules provided in the electrical charging network system 1 with each additional module added and each additional module removed.By ensuring that every second distribution unit 7, i.e. every sub-distribution unit (UVT), of the electrical charging network system 1 is designed to be connected to its assigned first distribution unit 5 in a modular manner, the scalability of the electrical charging network system 1 is guaranteed.

[0116] Likewise, each charging point unit 9 of the electric charging network system 1 is designed to be connected in a modular manner to the second distribution unit 7 to which the corresponding charging point unit 9 is assigned. Each charging point unit 9 of the electric charging network system 1 can therefore be understood as a module that can be added to and removed from the electric charging network system 1 as needed, whereby the full functionality of the electric charging network system 1 is still guaranteed for the other modules provided in the electric charging network system 1 with each additional module added and each additional module removed. Because each charging point unit 9 of the electric charging network system 1 is designed to be connected to its assigned second distribution unit 7 in a modular manner, the scalability of the electric charging network system 1 is ensured.

[0117] The electric charging network system 1 is therefore modular and energy-autonomous and expandable. Preferably, each first distribution unit 5, i.e., each sub-distribution unit plus (UVT+), has a capacity of up to 720 charging points, preferably with 22 kW each, so that each first distribution unit 5, i.e., each sub-distribution unit plus (UVT+), can preferably supply up to 720 charging point units, preferably with 22 kW each, with electrical energy. Preferably, each second distribution unit 7, i.e., each sub-distribution unit (UVT), converts the electrical voltage from medium voltage to low voltage. Preferably, each second distribution unit 7, i.e., each sub-distribution unit (UVT), supplies up to 340 charging points.

[0118] In particular, the electric charging network system 1 is a holistic ecosystem for e-charging infrastructure that effectively solves challenges such as grid infrastructure overload, supply bottlenecks, and / or location problems, and easily provides innovative charging points across a wide area. The electric charging network system 1 is designed to be expanded in conjunction with other systems, such as telecommunications, heating, or energy networks, thereby saving time and costs. For example, Power to the Street (PTTS) enables entire streets and city districts to be equipped with state-of-the-art charging infrastructure. Power to the Building (PTTB) allows, for example, shopping centers, underground parking garages, or stadiums to be retrofitted with numerous charging points.With Power to the Home (PTTH), for example, multi-family dwellings, businesses, and public service institutions can be retrofitted with numerous charging points. Users can choose between different charging modes. SCC Eco Charge primarily uses regional energy sources, SCC Priority Charge draws additional electricity from the national grid when needed to ensure immediate and maximum charging, SCC Eco Charge & Resell enables bidirectional charging and the feeding of stored energy back into the charging network, and SCC Public Use provides municipal facilities and public transport with access to the electric charging network system. In particular, the electric charging network system offers a modern, comprehensive solution for a nationwide EV charging infrastructure, as well as modular individual sections of such an infrastructure.

[0119] Preferably, the electric charging network system 1 is configured for bidirectional charging. Each first distribution unit 5, i.e., each UVT+, is configured to send control signals to the components of the electric charging network system 1, such as the charging point units, fast charging units, and storage units, so that a specific component or several specific components are supplied with electrical energy and electrical energy is discharged from a specific other component or several specific other components. For example, a specific fast charging unit 67 can be supplied with electrical energy, and simultaneously, electrical energy can be discharged from several specific charging point units and a specific storage unit 75, so that an electric vehicle's electrical energy storage device connected to the specific fast charging unit 67 can be charged.In particular, the electric charging network system is configured such that electrical energy is drawn from one or more specific components and can be supplied to one or more specific components via multiple voltage levels. This process can also be referred to as bidirectional charging across multiple voltage levels. Preferably, the electric charging network system 1 is configured to supply the power grid with electrical energy stored in an electric vehicle's energy storage system, which is connected to a charging point unit 9. This process can also be referred to as vehicle-to-grid (V2G). Vehicle-to-grid technology ensures intelligent sector coupling or the supply of power to a house during a power outage.Alternatively or additionally, the electric charging network system 1 is configured to supply an electrical energy storage device of another electric vehicle, which is connected to another charging point unit 9, with electrical energy stored in an electrical energy storage device of the electric vehicle already described, which is connected to a charging point unit 9. This process can also be referred to as vehicle-to-vehicle (V2V). Vehicle-to-vehicle operation ensures, for example, the supply of power to an electric vehicle during a power outage. Each first distribution unit 5, i.e., each UVT+, is configured to selectively control the energy flow in the electric charging network system 1 between all components of the electric charging network system 1 and between all components and the power grid 81.This is particularly advantageous compared to bidirectional charging known from the prior art, where electrical energy is fed into the distribution network and targeted, controlled distribution of the electrical energy is not possible. Furthermore, it has already been described that the electrical charging network system 1 can have one or more storage units 75, each of which can also be referred to as a megawatt storage unit or megawatt (MW) storage or large-scale storage. Additionally or alternatively, the electrical charging network system 1 can have one or more further storage units.Each additional storage unit can be, for example, a battery or a hydrogen storage unit, in particular with an electrolyzer coupled to it, which is designed to produce hydrogen and is coupled to the hydrogen storage unit in such a way that the produced hydrogen can be stored in the hydrogen storage unit. Each additional storage unit can be connected to the third distribution unit 11, i.e., the main distributor (HVT), one of the first distribution units, i.e., one of the sub-distributors Plus (UVT+), or one of the second distribution units, i.e., one of the sub-distributors (UVT), in order to be supplied with electrical energy, to store it, and to then make the stored electrical energy available again for charging the electrical energy storage systems of electric vehicles.

[0120] Furthermore, it has already been described that the electric charging network system 1 can have one fast charging unit 67 or several fast charging units. Additionally or alternatively, the electric charging network system 1 can have further fast charging units, such as a previously described megawatt charging unit 69 (MW charging unit) or several previously described megawatt charging units. Each fast charging unit 67 can be connected to the third distribution unit 11, i.e., the main distribution board (MDB), a corresponding first distribution unit 5, i.e., a corresponding sub-distribution board plus (SDB+), or a corresponding second distribution unit 7, i.e., a corresponding sub-distribution board (SDB).The third distribution unit 11, i.e., the main distribution board (HVT), each first distribution unit 5, i.e., each speaking sub-distribution board Plus (UVT+), and each second distribution unit 7, i.e., each corresponding sub-distribution board (UVT), has a corresponding connection section configured to be connected to a corresponding fast-charging unit 67. Additionally or alternatively, the electrical charging network system 1 can have one or more DC charging units. Each DC charging unit can be connected to the third distribution unit 11, i.e., the main distribution board (HVT), a corresponding first distribution unit 5, i.e., a corresponding sub-distribution board Plus (UVT+), or a corresponding second distribution unit 7, i.e., a corresponding sub-distribution board (UVT).The third distribution unit 11, i.e. the main distributor (HVT), each first distribution unit 5, i.e. each speaking sub-distributor Plus (UVT+), and each second distribution unit 7, i.e. each corresponding sub-distributor (UVT), has a corresponding connection section which is designed to be connected to a corresponding DC charging unit.Because the third distribution unit 11, i.e., the main distributor (HVT), each first distribution unit 5, i.e., each speaking sub-distributor Plus (UVT+), and each second distribution unit 7, i.e., each corresponding sub-distributor (UVT), each have a corresponding connection section, whereby a corresponding charging point unit can be connected to each connection section and is connected if necessary, a high area coverage with charging point units can be ensured particularly efficiently with the electric charging network system 1, especially with a low component requirement, so that all routes that can previously be travelled with a combustion engine vehicle can also be travelled with an electric car using the electric charging network system 1.

[0121] As previously described, the third distribution unit 11 can be referred to as the HVT (High-Voltage Distribution Unit). All energy sources and energy carriers can be centrally integrated in the HVT, such as self-sufficient energy sources (e.g., the renewable energy conversion facility 79, such as the solar park, the power grid 81, or a wind turbine) or storage units, such as the storage unit 57 in the form of a megawatt storage unit. The energy flow of each individual source can be measured in real time via the sensor units already described. Based on this data, the control unit 33 of the first distribution unit 5, i.e., the UVT+, decides which energy source is used primarily for supply.The control unit 33 of the first distribution unit 5, i.e., the UVT+, forwards control commands to the subordinate SCS (System Control Core) slave units, such as the control unit 33 of the third distribution unit 11, i.e., the HVT, thus fully controlling the internal energy network. With the transition from the HVT to the UVT+, an independent internal network begins, which is operated and controlled autonomously – independent of the public grid. The HVT can also be referred to as a hybrid connection point. The HVT is a central network node where several different energy sources and systems can be combined, coordinated, and controlled. For example, the HVT connects photovoltaic (PV) systems, conventional feed-in from the public grid and / or power plants, battery storage systems, or other storage solutions.The goal of the HVT (Hybrid Connection Point) is to intelligently combine various energy sources, measure the energy flow, control it using the UVT+ (Universal Load Transfer Controller), and feed it into the rest of the electrical charging network system 1 – particularly while adhering to grid requirements (e.g., voltage, frequency, power). The HVT incorporates the sensor units already described, with each sensor unit comprising a current sensor and / or a voltage sensor. The sensor units preferably monitor continuously: current (A), voltage (V), power (W), and, if applicable, reactive power and frequency. This enables precise, real-time monitoring of feed-in and consumption. Advantages of the HVT, i.e., the hybrid connection point, include: high security of supply through source diversity; optimized energy utilization and load balancing; relief and stabilization of the public grid; a basis for grid-supporting control energy; and compatibility with future smart grid architectures.The storage unit 75 assigned to the HVT is actively controlled. The storage unit 75 preferentially stores excess energy from each component 17 of the fourth voltage level (e.g., during low load in the electrical charging network system). The storage unit 75 feeds energy back into the rest of the electrical charging network system as needed.

[0122] For example, during periods of high load. The storage unit 75 serves to stabilize the grid by buffering frequency and voltage (frequency control, voltage control). The storage unit 75 can absorb load peaks or provide energy in the event of failure of individual sources (backup function).

[0123] As previously described, the first distribution unit 5 can be designated UVT+. All measurement data, particularly from the sensor units, from the entire electric charging network system converge in the control unit 33 of the first distribution unit 5, which can also be referred to as the SCC master. The control unit 33 of the first distribution unit 5 processes this data and generates: load distribution strategies, energy flow decisions, and charging point authorizations based on usage, capacity, and priority. Furthermore, the control unit 33 of the first distribution unit 5 controls the slave units, such as the control unit 33 of the third distribution unit.

[0124] The control unit 33 of the UVT+ (High-Voltage Distribution Unit II) supplies every second distribution unit 7 (UVT), every charging point unit 9, every fast-charging unit 67, and every storage unit 75 with control commands to ensure optimal and demand-oriented energy distribution within the internal network. The UVT+ can also be referred to as an intelligent control unit, EMS, or Energy Management System. The control unit 33 of the UVT+ analyzes sensor data and decides in real time on: feed-in priorities (e.g., photovoltaic (PV) system before grid feed-in); charging and discharging processes of the storage units; grid support measures (e.g., during voltage dips); optimization of self-consumption; and grid feed-in. The UVT+ can also be described as an intelligent medium-voltage interface with control function (especially 20 kV).The UVT+ is preferably not a conventional switchgear in the traditional sense, but rather functions as an intelligent control interface in the medium-voltage range (especially 20 kV). Preferably, however, the UVT+ also assumes the functions of a medium-voltage switchgear. The UVT+ performs a higher-level coordination and control function within the electrical charging network system 1, which can also be referred to as the energy distribution network. The UVT+ continuously analyzes the operating data of the overall system via connected sensors and sends control commands to other components of the electrical charging network system 1, in particular to the main distribution frame (MDF) (e.g., for regulating the feed-in power or voltage) and to the charging point units 9 (e.g., for enabling or disabling the load). Specifically, the UVT+ performs the following tasks: real-time data acquisition, especially from the sensor units and sensor modules.This includes, in particular, current, voltage, and power data from all outputs and inputs, as well as status monitoring of connected loads and energy sources. Energy flow control, especially coordination of energy distribution via digital control commands, specifically no mechanical switching within the UVT+ itself – all or most actions are performed via connected actuators (HVT or LP). Load management, especially identification and control of load priorities, dynamic load allocation, e.g., during peak loads, network bottlenecks, or redundancy situations. Network stabilization: especially frequency and voltage monitoring, reactive power requests, and power reduction or increase at the HVT and LP for network support.Bidirectional charging (V2G, V2V): The UVT+ manages bidirectional charging to integrate electric vehicles into the energy grid as flexible storage devices, thereby balancing peak loads, increasing grid stability, and enabling additional revenue models through energy feedback. Communication: in particular, interfaces to SCADA systems or cloud-based control centers, timely fault diagnosis, status feedback, and remote configuration. Data acquisition, IoT sensors, and smart city functions: The UVT+ centrally integrates IoT sensors and smart city functions, intelligently networks them, and processes the data in real time to enable efficient, adaptive infrastructure control.Each first distribution unit 5, i.e., each UVT+, is therefore configured to receive data from the third distribution unit 11, data from each of the corresponding first distribution unit 5's second distribution unit 7, data from each of the corresponding first distribution unit 5's second distribution unit 7's charging point unit 9, and, based on the received data, to control the energy flow in the electrical charging network system using the third distribution unit 11, each of the corresponding first distribution unit 5's second distribution unit 7, and each of the corresponding first distribution unit 5's second distribution unit 7's charging point unit 9.Preferably, each first distribution unit 5, i.e., each UVT+, is configured to receive data from the third distribution unit 11, data from each second distribution unit 7 assigned to the corresponding first distribution unit 5, data from each charging point unit 9 assigned to the corresponding first distribution unit 5, and data from each fast charging unit 67, and to control the energy flow in the electric charging network system using the third distribution unit 11, each second distribution unit 7 assigned to the corresponding first distribution unit 5, each charging point unit 9 assigned to the corresponding first distribution unit 5, and each fast charging unit 67.Preferably, each first distribution unit 5, i.e., each UVT+, is configured to receive data from the third distribution unit 11, data from each second distribution unit 7 assigned to the corresponding first distribution unit 5, data from each charging point unit 9 assigned to the corresponding first distribution unit 5, and data from each storage unit 75, and to control the energy flow in the electrical charging network system using the third distribution unit 11, each second distribution unit 7 assigned to the corresponding first distribution unit 5, each charging point unit 9 assigned to the corresponding first distribution unit 5, and each storage unit 75.Preferably, each first distribution unit 5, i.e., each UVT+, is configured to receive data from the third distribution unit 11, data from each second distribution unit 7 assigned to the corresponding first distribution unit 5, data from each charging point unit 9 assigned to the corresponding second distribution unit 7, data from each fast charging unit 67, and data from each storage unit 75, and to control the energy flow in the electric charging network system based on the received data using the third distribution unit 11, each second distribution unit 7 assigned to the corresponding first distribution unit 5, each charging point unit 9 assigned to the corresponding first distribution unit 5, each fast charging unit 67, and each storage unit 75. Each first distribution unit 5, i.e., each UVT+, is preferably configured to control the energy flow in the electric charging network system.Each first distribution unit 5 is connected to at least one associated second distribution unit 7 in such a way that each second distribution unit 7 can be supplied with electrical energy at a voltage on the second voltage level, and each second distribution unit 7 is in turn connected to at least one associated charging point unit 9 in such a way that each charging point unit 9 can be supplied with electrical energy at a voltage on the third voltage level. Thus, in the electrical charging network system 1, two voltage levels—namely the second voltage level and the third voltage level—are provided between each first distribution unit 5 (i.e., each UVT+) and each associated charging point unit 9.The control of the energy flow in the electric charging network system 1 therefore takes place centrally in the corresponding first distribution unit 5 and at a higher voltage level than is the case, for example, in prior art electric charging network systems where the energy flow takes place in several components directly connected to the charging point units. A resulting advantage of the electric charging network system 1 is that it can be expanded relatively easily with additional charging point units, particularly since relatively simple charging point units can be connected to already installed second distribution units, or, if necessary, relatively simple second distribution units can be connected to the first distribution unit 5, to which, in turn, relatively simple charging point units can be connected.In the illustrated embodiments of the electric charging network system 1, the control of the energy flow in the electric charging network system 1 takes place at the medium-voltage level in the UVT+ and not at the low-voltage level in a large number of smaller components. For example, the UVT+ can control 700 or 750 or even more charging point units.

[0125] As previously described, every second distribution unit 7 can be designated as a UVT (Distribution Unit 7). Each UVT can also be referred to as a transformer station. Each UVT can convert the energy coming from the internal medium-voltage network into low voltage. Furthermore, each UVT can activate or deactivate the charging point units assigned to it according to instructions from the SCC master. Thus, each charging point unit 9 is individually controlled according to load profile, charging program, or user requirements. Each UVT can also be referred to as a transformation and signal distribution unit.

[0126] Each UVT (Substation) includes a step-down and distribution transformer. Each UVT is a central system component that performs two essential tasks: voltage reduction from medium voltage (especially 20 kV) to low voltage (especially 0.4 kV) and processing and forwarding IP-based control and signal information, for example, from the UVT+. Each UVT thus provides a voltage conversion or transformer function. The first stage of each UVT involves the electrical transformation of the supply voltage from, in particular, 20 kV to, in particular, 0.4 kV, to make the energy usable for operating low-voltage loads.

[0127] Input side: particularly 20 kV (power supply to UVT+), output side: particularly 0.4 kV (towards charging point units), preferably designed as an oil-filled or dry-type transformer, integrated protection technology and measurement (e.g., current, voltage, temperature). Each UVT also provides intelligent signal distribution. A second section of each UVT performs a data processing function: It receives control commands and signals from the UVT+ and distributes them IP-based (Ethernet, TCP / IP) to the associated consumers, actuators, or subsystems. The tasks of each UVT include, in particular: receiving control commands (e.g., switching commands, power requests, status queries), addressing and forwarding them to the correct target systems (e.g., charging systems), network management: routing, logging, optionally firewall function or VLAN separation, communication protocols such as Modbus TCP, MQTT, IEC 61850, OPC UA (depending on the system environment).

[0128] As previously described, each charging point unit can also be referred to as a charging point (LP). As also previously described, each charging point unit 9 has a switching unit 49. The switching unit 49 of each charging point unit 9 can be controlled by the control unit 33 of the second distribution unit 7 assigned to the corresponding charging point unit 9, i.e., the UVT assigned to the corresponding charging point unit 9. The switching unit 49 of each charging point unit 9 then ensures the release of the energy flow to the corresponding energy storage device of the corresponding electric vehicle 13. The release of the energy flow to a specific electric vehicle 13 occurs exclusively upon instruction from the SCC master, i.e., the control unit 33 of the first distribution unit 5, and can be individually controlled according to user ID, charging profile, and / or energy availability.Each charging point unit 9 can also be referred to as an infrastructure connection point or IAP. The infrastructure connection point is the endpoint at the low-voltage level and fulfills three key functions: Charging point: Direct connection for end users (e.g., preferably two 22 kW charging points); IP-based control and data connection: Receiving control data from the UVT / UVT+, forwarding status or consumption data, especially to the UVT / UVT+; Integration of IoT sensors: Modular design allows the integration of IoT components, which can also be referred to as sensor modules, for monitoring the charging point units' environment, consumption, status, security, environmental data, smart city functions, advertising and marketing functions, and services such as parking management, traffic counting, etc. The sensors use the same infrastructure supply (power and data), which reduces installation effort.Typical IoT applications: temperature, air quality, presence, or energy consumption sensors. Control via UVT+: The entire energy and communication flow in each charging point unit 9 is controlled by the UVT+ via the UVT or UVTs, such as load enabling or disabling, assignment of energy priorities, configuration of IP components, control of IoT communication, and real-time monitoring of operating states.

[0129] As previously described, the charging point unit 9 has several sensor modules. The charging point unit 9 has a frame unit, which can also be referred to as the SCC Core Frame. The frame unit has several slots. Each slot is designed so that it can individually accommodate each of the multiple sensor modules 59. Furthermore, each sensor module 59 is designed so that it can be individually accommodated by each of the multiple slots. Thus, when a sensor module 59 is installed, it is held by its corresponding slot. Each sensor module 59 has a connection section, and each slot has a connection section, whereby each connection section of each sensor module 59 can be connected to each connection section of each slot. Each slot can also be referred to as a slot.The fact that the charging point unit 9 has the frame unit which has the multiple slots ensures that flexible integration of different components within a predefined frame system with defined dimensions and housings is possible.

[0130] The frame unit can have several sections, each of which can be called a frame module. The frame unit can therefore have multiple frame modules. The frame modules of the multiple frame modules are identical in structure. Each frame module has a first connecting section by which the corresponding frame module can be connected to a second connecting section of another frame module within the multiple frame modules. Furthermore, each frame module has a second connecting section by which the corresponding frame module can be connected to a first connecting section of another frame module within the multiple frame modules. The frame unit can thus have several identically constructed and interconnected frame modules, so that the frame unit can, for example, have stacked frame modules that are securely fixed to one another. Preferably, the frame unit has three frame modules.Preferably, each frame module has a height of 100 cm. Each frame module has several slots as previously described. Therefore, each frame module can be individually equipped with a wide variety of sensors according to customer requirements. This allows, for example, manufacturers of IoT sensors, monitoring systems, and other technologies to adapt and seamlessly integrate their existing components into the frame unit, the frame modules, and especially the slots.

[0131] As previously described, various sensor modules can be provided. For traffic control and monitoring, one or more sensor modules can incorporate one or more of the following sensors or detection devices: radar and lidar sensors, particularly for detecting vehicle movements, speeds, and distances – even under adverse weather conditions; AI-powered cameras, particularly for license plate recognition, traffic flow analysis, and traffic light monitoring; Bluetooth and Wi-Fi tracking, particularly for analyzing average travel time and congestion development through mobile device data collection; and license plate and vehicle identification sensors, particularly for use in automatic toll systems, parking enforcement, and traffic flow analysis. Parking fees can also be calculated using license plate recognition.Furthermore, for parking management, one or more sensor modules 59 may include one or more of the following sensors or detection devices: ultrasonic sensors, in particular for detecting available parking spaces in parking garages or on streets; AI-supported cameras, in particular for parking space monitoring and preventing illegal parking. Furthermore, for pedestrian and bicycle traffic detection, one or more sensor modules 59 may include one or more of the following sensors or detection devices: infrared sensors, in particular for detecting pedestrians and cyclists for, e.g., traffic light control and safety measures.

[0132] Thermal imaging cameras, especially for detecting people's movements even in poor lighting conditions; radar sensors, especially for detecting pedestrians at dangerous crossings. Furthermore, for Smart City & Environmental Monitoring, one or more sensor modules may include one or more of the following sensors or detection devices: multi-sensor weather stations, especially for recording temperature, humidity, wind speed, and precipitation to support traffic management and infrastructure maintenance; air quality sensors (NO2, CO2, particulate matter, ozone, VOCs), especially for measuring environmental pollution to support environmental zone regulations; noise sensors, especially for monitoring traffic noise to optimize noise abatement measures; shock and vibration sensors, especially for the early detection of road damage or structural changes to buildings.Furthermore, for intelligent street lighting and street monitoring, one or more sensor modules 59 may have one or more of the following sensors or detection devices: motion sensors (radar, PIR sensors), in particular for adapting the lighting to the traffic flow; light sensors, in particular for optimizing street lighting depending on ambient light; AI-supported cameras, in particular for detecting accidents or unusual activities.Furthermore, for safety and emergency management purposes, one or more sensor modules (59) may include one or more of the following sensors or detection devices: emergency call systems with cameras and microphones, in particular for rapid assistance in emergencies through integrated emergency call boxes; fire and smoke detectors, in particular for use in parking garages, facilities or critical infrastructure points; AI-supported surveillance cameras, in particular for analyzing crowd flows and detecting emergencies.

[0133] Various sensor modules have already been described, and the frame unit has several slots, each slot being designed to accommodate each of the 59 sensor modules individually. Similarly, each sensor module 59 can also be equipped with a technology capsule, designed to accommodate each slot. The technology capsule can also be referred to as a technology capsule module. The technology capsule module has a connection section that allows it to be connected to each connection section of each slot. For example, the technology capsule has a second charging connection point.The technology capsule preferably has two Type 2 sockets, allowing for particularly flexible expansion of the EV charging infrastructure, as it can preferably provide two 22 kW AC charging points for electric vehicles. The technology capsule also preferably includes the switching unit 49, the first electrical connection section 55, and the second electrical connection section 57 as described above. For example, in addition to the technology capsule module already described, the charging point unit may include another technology capsule module or modules, which may be identical to the technology capsule module already described or have a different design.

[0134] Just like each sensor module 59, one or more display modules can also be provided. Each display module is designed so that it can be accommodated in any slot. For example, for laser image display and holography, one or more display modules can have one or more of the following components: a laser projector, especially for the dynamic display of traffic and environmental information, navigation, advertising, or public notices on surfaces or as interactive projections; holographic displays, especially for 3D visualizations for interactive city information, safety instructions, or as wayfinding systems for autonomous driving and smart city applications.

[0135] Different data can therefore be recorded using the charging point unit 9 or any charging point unit of an electric charging network system.The electric vehicle charging network system can thus collect extensive data via various sensors and modules, such as traffic data, in particular vehicle movements, speeds, license plate recognition, and congestion; parking monitoring data, in particular parking space availability and illegal parking detection; pedestrian and bicycle traffic analysis data, in particular pedestrian flows, route usage, and transitional use; environmental monitoring data, in particular air quality, noise levels, vibrations, and structural changes; weather data, in particular temperature, humidity, wind speed, and precipitation; lighting and energy consumption data, in particular dynamic adjustment of street lighting depending on traffic and lighting conditions; and safety monitoring data, in particular emergency detection, accident detection, and fire and smoke detection.

[0136] The collected data is preferentially transferred from charging point unit 9 to a UVT (Universal Transfer Station) assigned to charging point unit 9, and then from that UVT to a UVT+ assigned to it. If multiple charging point units are used, corresponding data is transferred from each charging point unit 9 to a corresponding UVT assigned to it, and then from that UVT to the UVT+ assigned to it. This allows the data to be analyzed and used centrally. For example, traffic optimization can be implemented. In particular, the causes of congestion can be analyzed, dynamic traffic light sequences implemented, and intelligent traffic flow control can be implemented. Furthermore, efficient parking management can be carried out. Specifically, an automated parking guidance system can be operated, thus avoiding the need to search for parking spaces. This also supports urban planning and infrastructure optimization.In particular, highly frequented pedestrian and bicycle paths can be identified for better infrastructure planning. Furthermore, environmental and noise management can be supported. Specifically, real-time data can be used to regulate environmental zones, noise abatement measures, and urban air quality. Street lighting can also be operated adaptively. In particular, energy can be saved through demand-based lighting control. Finally, safety measures can be implemented. Specifically, early accident detection, emergency detection, and proactive measures can be carried out through AI-supported analysis.

[0137] The connection of different charging point units via the UVT with the UVT+, or the electric charging network system with multiple charging point units, can also be referred to as the SCC CoreFrame system and enables data-driven, intelligent city management that increases efficiency, sustainability, and safety. The SCC CoreFrame system and the SCC CoreFrame enable a flexible and future-proof infrastructure for urban areas by combining modular and intelligent technologies in a scalable system.

[0138] In particular, the electrical charging network system according to the invention offers the following advantages: Grid independence: Dedicated energy and data network from the main distribution frame; Energy self-sufficiency: Integration of storage systems and renewable energy sources; Centralized control: Intelligent load control via SCC master; Fine-grained control: Individual charging points can be controlled individually;

[0139] Scalability: Modularly expandable for any site size; Security & Redundancy: Dedicated network with monitoring of all energy flows.

[0140] The electric charging network system 1 can be described as an integrated charging and energy system for urban mobility and energy infrastructure. It can combine various energy sources (e.g., solar, wind, grid power) in an intelligent charging management system that can provide both DC fast charging stations and comprehensive AC charging points for electric vehicles. The system also serves as the foundation for a scalable public infrastructure, enabling the development of a charging and data network – including IoT sensors as a basis for modern smart cities, urban security, municipal resilience, and traffic, environmental, or condition monitoring. Furthermore, the system can utilize the energy storage capacity of connected electric vehicles as a decentralized, scalable large-scale storage system (vehicle-to-grid, V2G).Furthermore, a central large-scale storage system can be provided, which, for example, includes the storage units described. Preferably, the SCC master can control the energy flows so that, for example, energy is fed into the grid 81 when electricity prices are high and stored cost-effectively in the energy storage systems of the electric vehicles when there is overproduction. This creates an economically optimized and grid-supporting energy system with high benefits for municipal utilities, mobility providers, and local authorities.

[0141] As already described, Figures 7 to 14 show schematic representations of the fourth embodiment of the electrical charging network system 1 according to the invention, wherein Figure 8 shows a schematic representation of the third distribution unit 11, i.e., the main distributor (HVT), Figure 9 shows a schematic representation of the first distribution unit 5, i.e., the sub-distributor plus (UVT+), Figure 10 shows a schematic representation of a second distribution unit 7, i.e., a sub-distributor (UVT), Figure 11 shows a schematic representation of a charging point unit 9, Figure 12 shows several fast charging units, and Figure 13 shows several storage units. Each of these components can also be used as a component of each of the other embodiments of the electrical charging network system 1 according to the invention, so that the first embodiment, the second embodiment, and the third embodiment of the electrical charging network system 1 according to the invention can have each of these components once or multiple times.

[0142] Another aspect of the present invention is a computer program comprising commands that cause the electrical charging network system 1 to perform the steps of the described method. A further aspect of the present invention is a computer-readable medium on which the computer program is stored.

[0143] When means are described in connection with the present invention, such as means for real-time data acquisition and communication, these means are preferably a component of one component of the electric charging network system 1 or a component of several components of the electric charging network system 1, such that several components of the electric charging network system 1 have means and the means of the individual components are coordinated with each other to carry out the described steps. Each means preferably has a processor that can execute a corresponding computer program and a data memory on which the computer program is stored.

[0144] It should be further noted that "having" does not exclude any other elements or steps, and "a" or "an" does not exclude a plurality. It should also be noted that features described with reference to one of the above embodiments may also be used in combination with other features of other embodiments described above. Reference numerals in the claims are not to be considered as a limitation.
