Abstract
Description
Technical Field
[0001] The present invention relates to a method for connecting and controlling or charging an electrical device for terminal energy consumption and / or an electric vehicle according to the preamble of claim 1, a control system for connecting and controlling or charging an electrical device for terminal energy consumption and / or an electric vehicle according to the preamble of claim 8, an electrical device according to the preamble of claim 15, and an electric vehicle according to the preamble of claim 17. Background Art
[0002] In the past, electrical energy was mainly provided by coal, gas and / or nuclear power plants, which could be adjusted very well to the required energy demand. Today, renewable energy sources provided by solar and wind power plants already account for a larger proportion of electrical energy production. Today, there are already peaks in power generation, for example when the wind and the sun are strong at the same time. As a result, wind turbines "turn into the wind". But in the future, the proportion of renewable energy sources will increase further (keywords: climate change, digitalization, e-mobility, etc.).
[0003] On the other hand, more and more mass-produced electrical products, such as electrical equipment and / or electric vehicles (Elektrofahrzeuge), are used as energy users (Energieverbraucher, energy consumers).
[0004] These electrical devices can be battery-driven devices with rechargeable batteries, such as laptops, tablets, smart devices such as smartphones, smart speakers, smart watches, wireless sockets, smart appliances, standby functions, etc., or they can be household appliances that can run directly on the low-voltage power grid, such as televisions, washing machines, dishwashers or rice cookers.
[0005] For both types of consumers, the energy required by each consumer itself is small, but still represents a significant proportion of the total energy demand of all consumers available on the market. In addition, battery-operated consumers have batteries or accumulators in order to continue operating without a low-voltage grid connection.
[0006] Electric vehicles belong to the low-voltage range, especially electric vehicles, which charge their internal energy storage devices, such as large rechargeable batteries or rechargeable batteries, in a known manner at charging stations. In this regard, the energy required for the charging process of each electric vehicle is also relatively small, but when considering the sum of all electric vehicles in use (a number that will only increase and not decrease in the context of climate change), the energy demand in this area will account for a greater proportion than the above-mentioned electrical devices.
[0007] On the one hand, there are the peak power generation from renewable energy sources, and on the other hand, there is the energy demand of large-scale produced electrical products (including electrical equipment and / or electric vehicles), while the energy demand of individual electrical products is lower. The question that arises in the conflict between these two aspects is whether it is possible to ensure that these large-scale produced electrical products can be connected and / or charged for product operation when energy is available in the energy grid?
[0008] To date, there are no known solutions for such mass-produced power products. Individual solutions exist, such as remotely controlling the charging of electric vehicles and only authorizing charging when there is excess power in the grid. However, targeted, purposeful switching-on or charging control of mass-produced final energy-consuming power products, such as electrical appliances and / or electric vehicles, has not yet been disclosed. Summary of the invention
[0009] The object on which the invention is based is to propose a method and a control system for switching on or charging control of electrical devices and / or electric vehicles for terminal energy consumption, wherein the electrical device / electric vehicle can be controlled for a specific purpose at the energy consumption point in order to achieve the purpose of optimizing the energy costs of energy consumption by identifying the energy consumption point within a temporary operating duration or charging duration, at which the electrical device / electric vehicle consumes electrical energy by being switched on to an operating state or by charging a battery, such as a storage battery.
[0010] This object is achieved on the basis of the method defined in the preamble of claim 1 by means of the features specified in the characterizing clause of claim 1 .
[0011] Furthermore, the object is achieved on the basis of the control system defined in the preamble of claim 8 by means of the features specified in the characterizing clause of claim 8 .
[0012] Furthermore, the object is achieved on the basis of the electrical consumer defined in the preamble of claim 15 by the features specified in the characterizing clause of claim 15 .
[0013] Furthermore, this object is achieved on the basis of the electric vehicle defined in the preamble of claim 17 by the features specified in the characterizing clause of claim 17 .
[0014] The invention according to independent claims 1, 8, 15 and 17 is based on the idea that, by controlling the switching on or charging of an electrical consumer of an end energy user or controlling the charging of an electric vehicle, the electrical consumer or the electric vehicle can be connected via a power supply device via a grid connection point to a low-voltage grid with an energy consumption meter, into which the modulation signal can be modulated,
[0015] a. Generate a uniquely coded user point identification identifier (Verbraucherstellenidentifikationskennung) as signal information of the modulated signal on the low-voltage grid section between the energy consumption meter and the grid connection point,
[0016] b. identifying a unique code of a user point identification identifier contained in the modulated signal by a power supply device,
[0017] c. forwarding the user point identification identifier to the control unit of the electric device or electric vehicle,
[0018] d. Using the authorization request triggered by forwarding the user point identification identifier to allow access to the general electrical device or allow charging of the electrical device or allow charging of the electric vehicle, the control unit requests the use of the service provided by the service provider using the service provider server to optimize the energy cost of the electrical device / electric vehicle, wherein the service provider server can be through the "application programming interface" of the control unit <api>" module, through a logical communication link, according to the client-server principle, is connected to the electric device or electric vehicle as a client, and transmits the user point identification identifier to the service provider,
[0019] e. if the energy cost optimization is given according to the energy supply contract between the service provider and the energy provider, the service provider server of the service provider responds with a switch-on permission or a charging permission within the time window, according to which the electric device is automatically switched on or charged according to the energy supply conditions related to the contract in order to optimize the energy costs of the electric device, or the electric vehicle is charged according to the energy supply conditions related to the contract in order to optimize the energy costs of the electric vehicle,
[0020] f. Otherwise, if no connection permission or charging permission is given within the time window, the electrical device will be manually connected or charged in a conventional manner without performing the energy cost optimization, or the electric vehicle will be charged in a conventional manner without performing the energy cost optimization.
[0021] An advantageous development of the invention according to claims 2, 9, 16 and 18 is that the connection authorization and the subsequent automatic connection of the electrical consumer or the charging authorization and the subsequent charging of the electrical consumer or electric vehicle are carried out in association with the transmitted subscriber point identification identifier.
[0022] 1. Record the corresponding energy consumption of electrical equipment or electric vehicles,
[0023] 2. Notify the energy provider of the corresponding energy consumption through the service provider and
[0024] 3. The end energy user receives an energy cost discount from the energy provider for the notified energy consumption based on the contract-related energy cost optimization.
[0025] In this way and method, a service provider (for example, according to claims 7 and 14, the service provider can be the manufacturer of the electric device or electric vehicle, and the service provider server can be the server of the manufacturer of the electric device or electric vehicle) can also sell the energy consumption while selling the electric device or electric vehicle, so that the end energy user and the purchaser of the electric device or electric vehicle does not have to pay for it. In the present invention, the energy consumption cost of the electric device or electric vehicle can be borne by the service provider or manufacturer of the electric device or electric vehicle, which is an attractive and unknown method.
[0026] In another area, the book market, similar services exist in principle, with service providers such as Amazon TM Can Kindle TM The tablet downloads books via the mobile network, and the book terminal customer does not need to worry about the mobile contract or even the amount of data, because this is determined by the service provider, such as Amazon. TM Adjusted for end customers.
[0027] Furthermore, it is advantageous if the modulation signal is generated at regular time intervals according to claims 3 and 10. This makes it possible to flexibly cope with conflicts between power generation peaks of renewable energy sources and energy requirements of mass-produced electrical products at any point in time and to optimize the energy costs of electrical equipment or electric vehicles by means of contract-related energy supply conditions.
[0028] Furthermore, the invention is advantageously characterized in terms of the conflict between the peak power generation of renewable energy sources and the energy demand of mass-produced electrical products in that
[0029] - According to claims 4 and 11, the electrical equipment having the power supply device assigned to the electrical equipment is a battery-driven equipment (see Figure 1 option "A <Charging>" in the table above), for example, a laptop, tablet or smartphone, the power supply unit is used as an independent charging device to charge the batteries of the battery-operated device, such as accumulators, and the power supply unit can be connected to a mains connection socket as a mains connection point for charging (see Figure 1 option "A<Charge>"),
[0030] According to claims 5 and 12, the electrical consumer having the power supply device arranged in the electrical consumer is a household appliance (see Figure 1 option "B <Connected>" in the ), such as a television, washing machine, dishwasher or rice cooker, and the household appliance can be connected to a mains connection socket as a mains connection point (see Figure 1 option "B<On>"),
[0031] According to claims 6 and 13, the electric vehicle with the power supply device arranged in the electric vehicle is an electric vehicle, which can be connected to a charging station as a grid connection point via the power supply device in order to charge a rechargeable battery, such as a rechargeable storage battery.
[0032] The basic concept on which the present invention is based is summarized below with reference to an electrical consumer and a power supply device assigned to the electrical consumer, which represents all electrical consumers and electric vehicles, wherein the electrical consumer is, for example, a smartphone (smart terminal device) with a battery, and the power supply device can be connected to a grid connection socket as a grid connection point in order to charge the battery.
[0033] The starting point for the concept to be outlined is to understand how energy costs have been calculated to date. The grid operator installs energy consumption meters for end energy users in the low-voltage grid at energy consumption points (Energieverbrauchsstelle) with energy purchase points (Energieabnahmepunkt). The end energy user concludes an energy supply contract with the energy provider and informs the corresponding energy consumption meter at the energy purchase point. The "energy consumption" of the end user is set by the energy consumption meter. This must be transmitted to the energy provider at regular intervals, and the end energy user must pay for the purchased energy accordingly.
[0034] An overview of the program includes the following:
[0035] 1. In the area of the low-voltage power grid at the energy consumption point, upstream or downstream of the energy purchasing point of the terminal energy user, the low-voltage power grid section between the energy consumption meter and the power grid connection socket is modulated, and a uniquely coded identifier is input into the low-voltage power grid at the energy consumption point. The energy consumption point can be uniquely identified using or based on the identifier, so the identifier is a user point identification identifier.
[0036] 2. The power supply device of the smart phone can identify a uniquely coded user point identification identifier from the low-voltage power grid at the energy consumption point by reading or other means.
[0037] 3. The power supply device forwards the identified or read user point identification identifier to the smartphone.
[0038] 4. The smartphone asks the server of the service provider (eg, smartphone manufacturer and / or other provider) whether a charging process can be initiated to charge the battery, and transmits a unique user point identification identifier to the server.
[0039] 5. If the charging procedure is initiated, the smart terminal device records the energy consumed and reports it to the service provider or manufacturer.
[0040] 6. The service provider or manufacturer signs a corresponding energy supply contract with the energy provider, or even multiple energy supply contracts, so as to obtain energy from the energy provider when there is excess energy in the power grid. When the service provider or manufacturer obtains or purchases this excess energy, the energy provider will compensate it accordingly at a lower energy price.
[0041] 7. The manufacturer / supplier reports to the energy provider (eg directly or via the grid operator) how much of the cost of the acquired or procured energy is borne by which user point identification identifier.
[0042] 8. The energy provider offers corresponding discounts to end - energy users; although the consumption of smartphone charging is calculated through the energy consumption meter, the end - energy user will receive a discount for this consumption.
[0043] The components or points participating in the outlined scheme are:
[0044] A. Modulator
[0045] For example, the modulator is preferably either a function of the energy consumption meter ( Figure 1 and Figure 2 "Option I" in Figure 1 and Figure 2 ), in which case the energy consumption meter must be equipped with this function, or an additional device ( Figure 1 and Figure 2 "Option II"), which is installed downstream of the energy consumption meter. The modulator modulates a unique identifier as an electromagnetic signal into the low - voltage power grid at the energy consumption point. Specifically, it sets the corresponding frequency (e.g., 100 kHz) and the description (protocol) for encoding the identifier, such as a preamble and a UTF - 8 <UCS (Universal Coded Character Set) transformation format> encoded binary sequence of 64 subsequent characters.
[0046] The modulator itself requires a small amount of energy to modulate the signal. It is achieved through the interference generated by the electrical conductor installed near the modulator. The signal itself is also re - modulated onto the electrical conductor through interference (magnetic field). The modulator repeats sending the identifier to the low - voltage power grid at the energy consumption point at a set time interval (e.g., every minute).
[0047] B. Power supply device
[0048] The power supply device of the smartphone includes a function for identifying the unique encoding of the identifier from the low - voltage power grid at the energy consumption point, for example, through a set frequency such as 100 kHz. After identification, the unique identifier can be forwarded to the smartphone through the USB interface. In addition, the smartphone can also instruct the power supply device whether to start the charging process.
[0049] The power supply device also requires a small amount of energy to identify the uniquely - encoded identifier. If the power supply device is connected to the low - voltage power grid at the energy consumption point through a grid - connected socket, it will be activated and search for the unique identifier until the identifier is recognized or it gives up after a certain time (e.g., 5 minutes). If the identifier is recognized, it is saved in the persistent memory. After completing the identification or the identification task, the power supply device enters the "sleep" state until it is "awakened" by the smartphone through the USB interface.
[0050] C. Smartphone
[0051] The smartphone can read the unique identifier from the power supply device and, through the "Application Programming Interface" <api>"Module realizes the function of communicating with the service provider or manufacturer's server. Through the "Application Programming Interface <api>” module, the smartphone asks the server when it can start the charging process and transmits the unique identifier to the service provider or manufacturer's server.
[0052] The aim is to charge the smartphone's battery when there is too much renewable energy in the grid. Monitoring is the responsibility of the service provider or manufacturer.
[0053] If the battery of a smartphone is drained without charging permission from the service provider or manufacturer, the smartphone itself triggers the charging process via the power supply unit.
[0054] The energy consumed in the smartphone is measured and transmitted to the service provider or manufacturer.
[0055] D. Service provider or manufacturer
[0056] A service provider or manufacturer of a smartphone can advertise that the smartphone will cost nothing to operate. The only prerequisite is that there must be an infrastructure with modems. Installing these modems initially incurs additional costs.
[0057] However, once installed, they can be used in a variety of ways and in this sense represent a certain initial investment for the service provider or manufacturer.
[0058] The service provider or manufacturer aims to instruct the smartphone to start the charging process only when there is enough energy in the grid. To this end, the service provider or manufacturer provides negative control power, that is, the service provider or manufacturer receives money by purchasing excess energy from the energy grid when necessary. If necessary, the service provider or manufacturer can even receive the energy obtained free of charge and instruct the smartphone to start the charging process.
[0059] The service provider or manufacturer reports to the energy provider either directly or via the grid operator (in particular on the basis of a unique identifier) which energy consumption point in the low-voltage grid has "consumed" how much energy using the energy purchase point of the end energy user in the manner and method described for the scheme. The cost of this consumption is borne by the service provider or manufacturer. Ideally, this is a zero-sum game for the negative control power provided.
[0060] E. Energy providers / grid operators
[0061] Energy providers / grid operators are actually two different, separate entities that must coordinate with each other in the scenario outlined above. However, for simplicity, they are mentioned together. They also provide "application programming interfaces <api>"Module through which the service provider or manufacturer can report and indicate to the energy provider / grid operator how much energy costs are to be borne at the energy consumption point. The energy provider / grid operator charges these costs to the service provider or manufacturer and records the corresponding discount for the end energy user.
[0062] Provide this "application programming interface" for service providers or manufacturers <api>"The module is in the interest of energy providers / grid operators because it
[0063] -The share of renewable energy can be kept high without having to "remove" this generation.
[0064] -Electric energy sales remained unchanged.
[0065] - Other partners in the energy grid take on the responsibility of ensuring the stability of the energy grid.
[0066] The scheme outlined above can also be used to charge the battery of an electric vehicle. In addition, the scheme outlined above is also suitable for switching on an electric device without a battery, in which case switching on must be requested and permitted, rather than charging.
[0067] The idea outlined in the solution of the present invention and the advantages of the present invention are
[0068] 1. On the one hand, smartphones can identify themselves, and on the other hand, they can make specific plans for energy consumption based on the energy supply contract signed with the energy provider.
[0069] 2. It is possible that the service provider or manufacturer of the smartphone will bear the energy costs. In this way and method, the service provider or manufacturer may even make money in the end. BRIEF DESCRIPTION OF THE DRAWINGS
[0070] More advantages of the present invention will be described below. Figure 1 and Figure 2 The present invention is described in the following description of an embodiment.
[0071] Figure 1 A control system for connecting or charging a terminal energy consuming electrical device is shown.
[0072] Figure 2 A control system for charging control of an electric vehicle for terminal energy consumption is shown. DETAILED DESCRIPTION
[0073] Figure 1 A control system STGA for controlling the switching on or charging of electrical consumers of final energy consumption is shown, with an electrical consumer EG of an energy end user EEV, which forms an energy consumption point with an energy purchasing point in a low-voltage network NSN.
[0074] The low-voltage grid NSN is connected to the substation TS of the high-voltage grid HSN via an underground cable EKB. The high-voltage grid HSN is operated by the grid operator NBT, which in turn is connected to the energy provider EAB. In the low-voltage grid NSN, an energy consumption meter EVZ and a grid connection point NAS are arranged on the low-voltage grid section NSNTS to form an energy consumption point. The energy consumption meter EVZ records the energy consumed by the terminal energy user EEV, and thereby generates an energy consumption value EVW, which is provided to the energy provider EAB through the grid operator NBT during the PULL or PUSH mechanism. Based on the provided energy consumption value EVW, the energy provider EAB finds out the energy cost EK of the energy consumption recorded by the energy consumption meter EVZ according to the energy supply contract between the energy provider EAB and the terminal energy user EEV, and notifies it to the terminal energy user EEV.
[0075] The electrical equipment EG of the final energy user can be connected to the low-voltage network NSN via the grid connection point NAS by means of a power supply device NZT, which is either assigned to the electrical equipment EG as an independent device as in embodiment 1, or is a component of the electrical equipment EG and is arranged in the electrical equipment EG as in embodiment 2. In this case, the grid connection point NAS is, for example, a grid connection socket NASD or the like.
[0076] In the first embodiment, the electrical consumer EG is a battery-operated device and therefore has a battery BAT, for example in the form of a storage battery. In this case, the power supply device NZT assigned to the battery-operated electrical consumer EG as an independent device is used to charge the battery BAT (option "A <charging>"). The battery-operated electrical consumer EG is preferably a laptop, a tablet or a smartphone, but can also be any other battery-operated or storage battery-operated device, which is connected to the grid connection socket NASD via the power supply device NZT designed as an independent device for charging.
[0077] In the second embodiment, the electrical consumer EG is a household appliance or any other non-battery or accumulator-driven device, which is directly connected to the mains connection socket NASD for the supply of current and only needs to be switched on during commissioning (option "B <Switch on>"), which is usually done manually. The electrical consumer EG operated directly on the low-voltage mains is preferably a television, a washing machine, a dishwasher or an electric oven, but can also be any other device operated directly on the low-voltage mains.
[0078] In order to Figure 1 Both embodiments 1 and 2 are valid in that, on the one hand, the battery BAT and the electrical consumer EG with the power supply device NZT arranged therein are each represented by a dashed rectangle.
[0079] In order to control the connection or charging of energy-consuming electrical equipment, the control system STGA includes a modulator MOD in the energy consumption point of the terminal energy user EEV, by which the modulation signal MDS can be modulated into the low-voltage power grid NSN. The modulation signal MDS is used to generate a uniquely encoded user point identification identifier VSIK as signal information to identify the energy consumption point of the terminal energy user EEV. The user point identification identifier VSIK is generated on the low-voltage power grid section NSNTS between the energy consumption meter EVZ and the grid connection point NAS or the grid connection socket NASD. The modulator MOD is preferably arranged on this section of the low-voltage power grid NSN, so that the modulator MOD is either integrated into the energy consumption meter EVZ for cost and simplicity (option "I"), or placed in an additional device ZG installed on the section with additional installation costs (option "II"). However, the modulator MOD can also be arranged in the grid connection point NAS or the grid connection socket NASD.
[0080] Furthermore, the modulator MOD is designed to generate a modulation signal MDS with a subscriber point identification identifier VSIK at regular time intervals.
[0081] In order to enable the power supply device NZT in the two embodiments 1 and 2 of the terminal device EG to identify the uniquely coded subscriber point identification identifier VSIK when the terminal device EG is connected to the low-voltage power grid NSN having the modulation signal MDS and the subscriber point identification identifier VSIK modulated therein via the power supply device NZT via the power connection point NAS or the power connection socket NASD, the power supply device NZT has an identification device EKE specially designed for this purpose, which is correspondingly constructed to identify the uniquely coded subscriber point identification identifier VSIK.
[0082] After the identification device EKE identifies the user point identification identifier VSIK, it forwards it wtg to the control unit STE included in the power device EG and connected to the identification device EKE.
[0083] For switching on or charging control, the control unit STE contains an "application programming interface <api>"Module API-M, through which the electrical equipment EG can communicate via the logical communication link KV log A connection to a service provider server SAB-SV is provided to use services provided by the service provider SAB using the service provider server SAB-SV to optimize the energy costs EK of the electrical consumer EG, wherein the electrical consumer EG operates as a client and the service provider server SAB-SV operates as a server according to the client-server principle.
[0084] With "Application Programming Interface <api>The control unit STE of the module API-M is designed to request the use of energy cost optimization on the service provider server SAB-SV with an authorization request triggered by forwarding the user point identification identifier VSIK to allow the switching on of the EFG or to allow the charging of the electrical device EG LFG and to transmit the user point identification identifier VSIK to the service provider server SAB-SV.
[0085] If energy cost optimization is requested based on the energy supply contract ELK concluded between the service provider SAB and the energy provider EAB, then as a reaction to this request the service provider server SAB-SV of the service provider SAB communicates via the logical communication link KV log and "Application Programming Interface <api>The module API-M responds atw within a time window to issue a switch-on permission EFG in the embodiment 2 of the electrical consumer EG or a charge permission LFG in the embodiment 1 of the electrical consumer EG. The duration of the time window is preferably from a few seconds to one or two minutes.
[0086] Thus, in the case of embodiment 2 of the electric consumer EG, the electric consumer EG is automatically switched on according to the contract-related energy supply conditions in order to optimize the energy costs of the electric consumer EG, for example for temporary operation of the electric consumer EG, and in the case of embodiment 2 of the electric consumer EG, the electric consumer EG is charged according to the contract-related energy supply conditions in order to optimize the energy costs of the electric consumer EG. The automatic switching on or charging is respectively initiated by the control unit STE.
[0087] For example, charging can be performed in this way: if the electrical device EG is already connected to the power supply device NZT constructed as an independent device, but no charging current flows, the control unit STE will automatically start the charging process according to the charging permission LFG, and charge the battery BAT or storage battery of the electrical device EG by the flow of charging current.
[0088] However, if no switching on enable EFG or charging enable LFG is issued within the time window, the electrical consumer EG is manually switched on in a conventional manner or charged in a conventional manner without the above-described energy cost optimization taking place.
[0089] However, if the electric consumer EG is switched on or charged, the energy consumed in the temporary operation due to switching on or the energy consumed for charging the electric consumer EG is recorded in the electric consumer EG.
[0090] For this purpose, the control unit STE comprises an energy consumption measuring device EVME, wherein the control unit STE is configured in such a way that, with the connection permission EFG carried out in connection with the transmitted user point identification identifier VSIK and the subsequent automatic connection of the electric consumer EG, or with the charging permission LFG carried out and the subsequent charging of the electric consumer EG, the energy consumption EV of the electric consumer EG, i.e. the consumed energy, is recorded and displayed via the "application programming interface <api>Module API-M and logical communication link KV log The corresponding energy consumption EV is notified to the service provider SAB, and the service provider forwards the notified energy consumption EV to the energy provider EAB, so that the end energy user EEV obtains an energy cost discount EKR of the energy cost EK charged by the energy provider EAB to the end energy user EEV for the notified energy consumption EV based on the energy cost optimization related to the contract.
[0091] Figure 2 A control system STGA for controlling the switching on or charging of end-energy consuming electrical devices is shown, with an electric vehicle EFZ having an end-energy user EEV (eg the driver of the electric vehicle) which forms an energy consumption point with an energy purchasing point in the low-voltage network NSN.
[0092] The low-voltage grid NSN is connected to the substation TS of the high-voltage grid HSN via an underground cable EKB. The high-voltage grid HSN is operated by the grid operator NBT, which in turn is connected to the energy provider EAB. In the low-voltage grid NSN, energy consumption meters EVZ and grid connection points NAS are arranged on the low-voltage grid section NSNTS to form energy consumption points. The energy consumption meter EVZ records the energy consumed by the terminal energy user EEV, and thereby generates an energy consumption value EVW, which is provided to the energy provider EAB through the grid operator NBT during the PULL or PUSH mechanism. Based on the provided energy consumption value EVW, the energy provider EAB finds out the energy cost EK of the energy consumption recorded in the energy consumption meter EVZ according to the energy supply contract between the energy provider EAB and the terminal energy user EEV, and notifies it to the terminal energy user EEV.
[0093] The electric vehicle EFZ of the end energy user can be connected to the low-voltage grid NSN via a grid connection point NAS using a power supply device NZT arranged in the electric vehicle EFZ. In this case, the grid connection point NAS is, for example, a charging station LST for the electric vehicle.
[0094] As is known, the electric vehicle EFZ has a rechargeable battery LBAT, for example in the form of a storage battery. In order to charge the rechargeable battery LBAT, the electric vehicle EFZ is connected to a charging station LST via a power supply device NZT.
[0095] In order to control the charging of electric vehicles with terminal energy consumption, the control system STGA includes a modulator MOD in the energy consumption point of the terminal energy user EEV, by which the modulation signal MDS can be modulated into the low-voltage power grid NSN. The modulation signal MDS is used to generate the user point identification identifier VSIK uniquely encoded by ezg as signal information to identify the energy consumption point of the terminal energy user EEV. The user point identification identifier VSIK is generated on the low-voltage power grid section NSNTS between the energy consumption meter EVZ and the grid connection point NAS or the charging station LST. The modulator MOD is preferably arranged on this section of the low-voltage power grid NSN, so that the modulator MOD is either integrated into the energy consumption meter EVZ for cost and simplicity (option "I"), or placed in an additional device ZG installed on the section with additional installation costs (option "II"). However, the modulator MOD can also be arranged in the grid connection point NAS or the charging station LST.
[0096] Furthermore, the modulator MOD is designed to generate a modulation signal MDS with a subscriber point identification identifier VSIK at regular time intervals.
[0097] In order to enable the power supply device NZT to identify the uniquely coded user point identification identifier VSIK when the electric vehicle EFZ is connected via the power supply device NZT via the power connection point NAS or the power charging station LST to the low-voltage power grid NSN having the modulation signal MDS and the user point identification identifier VSIK modulated there, the power supply device NZT has an identification device EKE specially designed for this purpose, which is correspondingly constructed to identify the uniquely coded user point identification identifier VSIK.
[0098] After the identification device EKE has identified the user point identification identifier VSIK, it forwards it wtg to a control unit STE contained in the electric vehicle EFZ and connected to the identification device EKE.
[0099] For switching on or charging control, the control unit STE contains an "application programming interface <api>"Module API-M, through which the electric vehicle EFZ can communicate via the logical communication link KV log A connection to a service provider server SAB-SV is provided to use services provided by the service provider SAB using the service provider server SAB-SV to optimize the energy costs EK of the electric vehicle EFZ, wherein the electric vehicle EFZ operates as a client and the service provider server SAB-SV operates as a server according to the client-server principle.
