[0001] This utility model relates to the field of new energy charging technology, and in particular to a supercharging device and supercharging system. Background Technology

[0002] The new energy vehicle industry has become an important component of the national new power system and energy strategy. With the industry's development, new energy vehicle charging infrastructure has shown a trend towards faster, more concentrated, and more diverse development. Among them, supercharging stations are high-power charging facilities that can provide fast charging services for new energy vehicles, significantly reducing charging time.

[0003] However, current supercharging stations have the following problems:

[0004] (1) Supercharging equipment brings huge expansion pressure to urban power grids. The smallest supercharging station needs to expand the power grid by more than 1250kVA. Moreover, my country's power system has a multi-level architecture, which makes the power system relatively complex, resulting in scarce urban distribution network resources and difficulty in expansion.

[0005] (2) Currently, urban land resources are scarce, and the supercharging host and other equipment such as power distribution cabinets of supercharging stations adopt a decentralized deployment scheme, which covers a large area and has a long construction period, thus leading to the problem of high difficulty in the renovation of existing stations. Utility Model Content

[0006] The purpose of this invention is to provide a supercharging device that can reduce the load pressure on the power grid transformer caused by the supercharging station and ensure the charging efficiency of the charging pile.

When the electricity price is at off-peak price, the microgrid controller host is used to start the charging mode to charge the energy storage module until a predetermined amount of electricity is reached.

[0014] In one embodiment of this application, the supercharging device includes an air-cooling mechanism for cooling the supercharging host and / or the energy storage module.

[0015] In one embodiment of this application, the supercharging device includes a liquid cooling mechanism for cooling the energy storage module and / or the supercharging host.

[0016] In one embodiment of this application, the supercharging device includes a lighting system and a fire protection system, both of which are installed inside the housing.

[0017] This application also provides a supercharging system, which includes at least one charging terminal and any of the supercharging devices described in the present application, wherein the charging terminal is disposed outside the housing and electrically connected to the supercharging host inside the housing via a cable.

[0021] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0022] In this invention, the supercharging device includes a supercharger, a control module, a power distribution cabinet, an energy storage module, and a housing. The power distribution cabinet is used to electrically connect to an external power source, such as the power grid. The supercharger is electrically connected to the power distribution cabinet, and the energy storage module is electrically connected to the power distribution cabinet via an energy storage converter system, enabling both the supercharger and the energy storage module to receive electrical energy from the power distribution cabinet. The energy storage module stores electrical energy and is also electrically connected to the supercharger via the energy storage converter system, allowing the energy storage module to supply electrical energy to the supercharger. The energy management system can collect and manage parameters such as battery voltage, current, and temperature of the energy storage module. The supercharger is electrically connected to a charging terminal, which is used to connect to electrical equipment to charge or supply power to the equipment.

[0023] The power distribution cabinet, supercharger, control module, and energy storage module are integrated into a single enclosure. This allows the energy storage module to work in tandem with the power grid to supply power to the supercharger, thereby reducing the load on the supercharger from external power sources and alleviating strain on urban power grids. Furthermore, the supercharger can be deployed modularly, saving land area and shortening on-site construction time, thus addressing the scarcity of urban land resources and the difficulty of retrofitting existing facilities.

[0030] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Supercharging equipment (i.e., super-fast charging station equipment) puts enormous pressure on the expansion of urban power grids. Even the smallest supercharging station requires an expansion of the power grid by more than 1250kVA. Furthermore, my country's power system has a multi-level architecture, which makes the power system relatively complex, resulting in scarce urban distribution network resources and difficulty in expansion.

[0034] Currently, most operating supercharging and energy storage stations adopt a decentralized deployment scheme, which involves a large land area and a long construction period. This results in a significant workload and long construction period required to convert existing charging stations into supercharging stations, and also presents equipment compatibility issues. Therefore, this paper proposes a supercharging device to solve the above problems.

[0035] The solution is further illustrated by the following examples:

[0036] Figure 1 This is a schematic diagram of the supercharging system according to an embodiment of the present invention. Figure 2 yes Figure 1 Another schematic diagram of the supercharging system. Figure 3 This is a schematic diagram of the supercharging device according to an embodiment of the present invention. Figure 4 yes Figure 3 Another schematic diagram of the supercharging device.

[0037] Please see Figure 1 and Figure 2 The supercharging system of this embodiment can be applied to new energy vehicle charging stations to provide fast charging for new energy vehicles 7.

[0038] This utility model also provides a supercharging system, which includes at least one charging terminal 2 and a supercharging device. The supercharging device may include a supercharging host 1, a control module 3, a power distribution cabinet 4, an energy storage module 5, and a housing 10.

[0039] Understandably, the supercharging system can also be used to power or charge other electrical devices, such as mobile energy storage vehicles and power supply in remote areas.

[0040] In this embodiment, the container 10 can be a shipping container.

[0041] The charging terminal 2 is located outside the housing 10 and is electrically connected to the supercharger 1 inside the housing 10 via a cable. The number of charging terminals 2 can be configured as needed. Specifically, the charging terminal 2 can be a charging gun that can connect to the charging interface of a new energy vehicle.

[0042] See Figure 3 and Figure 4 The enclosure 10 contains multiple compartments 11 for installing the supercharging host 1, control module 3, power distribution cabinet 4, and energy storage module 5, respectively. In other words, the supercharging device integrates the supercharging host 1, control module 3, power distribution cabinet 4, and energy storage module 5 within the enclosure 10, enabling rapid deployment and reducing the footprint of the supercharging energy storage station. Simultaneously, the supercharging device can shorten the on-site construction period and address issues such as the scarcity of urban land resources.

[0043] Specifically, the arrangement of each accommodating compartment 11 can be configured according to actual needs, such as... Figure 3 and Figure 4 The supercharging devices shown are arranged in two ways.

[0044] like Figure 3As shown, the enclosure 10 includes a first compartment 111, a second compartment 112, a third compartment 113, and a fourth compartment 114 separated by partitions. The supercharger 1 is located in the first compartment 111, the control module 3 is located in the second compartment 112, the power distribution cabinet 4 is located in the third compartment 113, and the energy storage module 5 is located in the fourth compartment 114.

[0045] The first compartment 111 is located at one end of the container 10, while the third compartment 113 and the fourth compartment 114 are arranged side by side at the other end of the container 10. The control module 3 is located between the first compartment 111 and the third compartment 113 and the fourth compartment 114. It should be noted that the control module 3 is located near the middle position, which facilitates the electrical / communication connection between the control module 3 and the equipment in each compartment, and also helps to balance the overall weight of the container 10. The supercharger 1, the energy storage module 5, and the power distribution cabinet 4 are located at both ends for easy transportation and hoisting.

[0046] In some other embodiments, such as Figure 4 As shown, the first compartment 111 is located at one end of the box 10, the second compartment 112 is located at the other end of the box 10, the third compartment 113 is located between the first compartment 111 and the second compartment 112 and on the side close to the first compartment 111, and the fourth compartment 114 is located between the second compartment 112 and the third compartment 113.

[0047] In this embodiment, the supercharging device may further include an internal transformer, which is located within the third compartment 113. Specifically, the third compartment 113 houses both the internal transformer and the distribution cabinet 4, meaning that the transformer and distribution cabinet are integrated within the third compartment 113, facilitating the connection of the supercharging device to the urban power grid. Specifically, the internal transformer is connected to an external power supply 6 to boost or reduce the voltage of the urban power grid to the voltage used by the supercharging device. Furthermore, the distribution cabinet 4 is electrically connected to the internal transformer and to the supercharging host 1 and the energy storage module 5 to supply power to them.

[0048] Meanwhile, an air-cooling mechanism is installed inside the housing compartment 11 for housing the supercharger 1. The air-cooling mechanism is used to cool the supercharger 1 and ensure its safe operation. Simultaneously, a liquid-cooling mechanism is installed inside the housing compartment 11 for housing the energy storage module 5. The liquid-cooling mechanism is used to cool the energy storage module 5, thereby ensuring that the battery pack in the energy storage module 5 can safely store energy.

[0049] Understandably, as an alternative, the supercharger 1 can be cooled using a liquid cooling system, and / or the energy storage module can be cooled using an air cooling system.

[0050] In some other embodiments, the transformer may be located outside the enclosure. The supercharging system may include an external transformer located outside the enclosure 10, which is electrically connected to the distribution cabinet 4 via a cable.

[0051] In addition, the supercharging unit may also include a lighting system and a fire suppression system. Both the lighting system and the fire suppression system are installed inside the accommodating compartment 11 to facilitate the use of the supercharging unit and ensure its safe operation.

[0052] It should be noted that the supercharging device can quickly add a supercharging host to an existing charging station and is compatible with fast charging terminals, thereby solving the problem of the difficulty in upgrading existing charging stations.

[0053] In this embodiment, the charging terminal 2 is connected to the supercharger host 1 and located outside the housing 10. It should be noted that multiple charging terminals 2 can be provided, and all multiple charging terminals 2 are connected to the supercharger host 1 and located outside the housing 10 to facilitate connection with and charging of the new energy vehicle 7.

[0054] In addition, the energy storage module 5 includes at least one battery cluster. The battery cluster may be equipped with a battery pack and a high-voltage box system, enabling the energy storage module 5 to store energy and perform charging and discharging.

[0055] Distribution cabinet 4 can be used to connect to an external power source 6. It should be noted that the external power source 6 is primarily the city power grid, or it can be a power generation device, etc., to provide electrical energy to distribution cabinet 4. The power grid is connected to distribution cabinet 4 through an external transformer or an internal transformer.

[0056] The supercharger 1 is electrically connected to the power distribution cabinet 4, enabling it to receive power from the cabinet. Simultaneously, the supercharger 1 is also electrically connected to the charging terminal 2, which can be a charging gun. The charging terminal 2 connects to the new energy vehicle 7 to charge the vehicle.

[0057] The energy storage module 5 is electrically connected to the distribution cabinet 4 via the energy storage converter system, enabling the energy storage module 5 to receive and store electrical energy supplied by the distribution cabinet 4. In this embodiment, the energy storage module 5 is also electrically connected to the supercharger 1 via the energy storage converter system to supply electrical energy to the supercharger 1.

[0058] In some embodiments, the control module 3 includes an energy management system and an energy storage converter system. The energy management system is communicatively connected and / or electrically connected to the energy storage converter system and the energy storage module 5, respectively. The energy storage converter system is electrically connected to the energy storage module 5, the power distribution cabinet 4, and the supercharger 1, respectively.

[0059] The communication connection can be wired or wireless, for example, using a serial communication interface standard.

[0060] The control module 3 also includes an electricity meter, which is communicatively connected to the energy management system to monitor the downlink power of the supercharger 1. Furthermore, the energy management system is communicatively and / or electrically connected to the energy storage module 5 to monitor the real-time power of the energy storage module 5. The energy management system can also control the on / off connection between the energy storage module 5 and the supercharger 1.

[0061] In some embodiments, the control module 3 further includes a microgrid controller host, which is communicatively connected and / or electrically connected to the power distribution cabinet 4, the supercharger host 1, the energy management system and the energy storage converter system.

[0062] Specifically, when the electricity price is at its peak and the control module 3 detects that the downstream power of the supercharger 1 is greater than the rated power of the energy storage converter system, the microgrid controller starts the energy storage converter system and energy storage module 5. Energy storage module 5 and the external power source 6 (specifically the power grid) together supply power to the supercharger 1, ensuring that the supercharger 1 can charge the new energy vehicle 7 at full load power. This ensures the charging speed and efficiency of the supercharger station without modifying the urban power grid. When the energy storage module 5's charge is less than the minimum rated charge, the energy storage module 5 stops discharging.

[0063] When the electricity price is at the off-peak price, the microgrid controller starts the charging mode, and the energy management system controls the energy storage module 5 to charge until the predetermined amount of electricity is reached, which can be 90%.

[0064] It should be noted that the downlink power of the supercharger refers to the maximum output power that the supercharger can provide within a certain period of time.

[0065] Furthermore, in this embodiment, the minimum rated capacity of the energy storage module 5 can be set to 10% of the total capacity of the energy storage battery. That is, when the capacity of the energy storage module 5 is less than 10% of the total battery capacity, the energy storage module 5 stops discharging to protect the energy storage battery. Simultaneously, when the capacity of the energy storage battery is greater than 90%, the distribution cabinet 4 stops charging the energy storage module 5, thereby protecting the energy storage battery.

[0066] In this embodiment, a power distribution cabinet 4 and an internal transformer may be installed inside the third compartment 113. The internal transformer is connected to an external power source 6 to reduce the voltage of the urban power grid to the voltage used by the system. The internal transformer is connected to the power distribution cabinet 4, enabling the power distribution cabinet 4 to allocate power according to the power needs of each module.

[0067] In this embodiment, the control module 3 may include an energy management system, an energy storage converter system, and a microgrid controller host. The energy management system is configured as an energy storage EMS system, and the energy storage converter system is configured as an energy storage PCS system. The energy storage PCS system is electrically connected to the energy storage module 5, and the energy storage module 5 is charged or discharged through the energy storage PCS system. The energy storage EMS system is communicatively / electrically connected to the energy storage PCS system for monitoring and collecting the real-time power of the energy storage module 5.

[0068] The microgrid controller host is connected to the power distribution cabinet 4, the supercharging host 1, the energy management system and the energy storage converter system via communication and / or electrical connection.

[0069] The microgrid controller host is connected to the energy storage EMS system via communication and / or electrical connection. The microgrid controller host can receive data such as downlink power and real-time power consumption fed back by the energy storage EMS system, and control the operation of the distribution cabinet 4, the supercharging host 1 and the energy storage module 5 based on the downlink power and real-time power consumption data.

[0070] During the grid parity period, the external power source 6, i.e., the power grid, directly supplies power to the supercharger 1 via the distribution cabinet 4. The energy storage module 5 prioritizes to compensate for the peak power consumption of the supercharger 1. However, when the supercharger 1 is not in peak power consumption and its downstream power exceeds the rated power of the energy storage converter system, if the energy storage module 5's charge is detected to be more than 10% of its capacitance during the grid parity period, the energy storage PCS system can control the energy storage module 5 to discharge to the supercharger 1, so that it can supply power to the supercharger 1 together with the external power source 6.

[0071] Therefore, the above control strategy can both enable the energy storage module 5 to make up for the power demand of the supercharging host 1 and reduce the overall power cost of the supercharging system.

[0072] In some embodiments, the supercharging system further includes photovoltaic (PV) modules. These PV modules include photovoltaic panels and PV inverters, etc. The photovoltaic panels are disposed outside the housing 10, and the PV modules are electrically connected to at least one of the distribution cabinet 4, energy storage module 5, or control module 3. Specifically, the PV modules are electrically connected to the distribution cabinet 4, energy storage module 5, and control module 3, respectively. The PV modules convert solar energy into electrical energy and store it in the energy storage module, or supply power to the supercharging host via the distribution cabinet.

[0073] In some embodiments, the supercharging system further includes a bidirectional charging pile 8. The bidirectional charging pile 8 is electrically connected to the power distribution cabinet 4 and can be connected to the new energy vehicle 7 for charging the new energy vehicle 7. Specifically, the bidirectional charging pile 8 is equipped with a charging gun and can be connected to the new energy vehicle 7 to charge it. In this case, the bidirectional charging pile 8 is powered by an external power source 6, i.e., by the urban power grid, to charge the new energy vehicle 7.

[0074] Meanwhile, the bidirectional charging pile 8 can also be connected to the mobile energy storage unit 9 to distribute the power from the mobile energy storage unit 9 to the distribution cabinet 4, thereby supplying the power from the mobile energy storage unit 9 to the supercharger 1 or the energy storage module 5 to compensate for the power supply needs of the supercharger 1. Therefore, the bidirectional charging pile 8 and the mobile energy storage unit 9 can also ensure the charging efficiency of the supercharger 1 and avoid the supercharger equipment from putting enormous expansion pressure on the urban power grid.

[0075] In summary, the supercharging system includes a supercharger 1, a charging terminal 2, a control module 3, a power distribution cabinet 4, and an energy storage module 5. The power distribution cabinet 4 connects to an external power source 6. Both the supercharger 1 and the energy storage module 5 are connected to the power distribution cabinet 4, enabling them to receive power from it. The energy storage module 5 stores electrical energy and is also connected to the supercharger 1, allowing it to supply power to the supercharger 1. The supercharger 1 connects to the charging terminal 2, which connects to the new energy vehicle 7 to charge it. The control module 3 connects the supercharger 1, the power distribution cabinet 4, and the energy storage module 5.

[0076] The power distribution cabinet 4, supercharger 1, control module 3, and energy storage module 5 are integrated into the same enclosure. This allows the energy storage module 5 to work in conjunction with the power grid to supply power to the supercharger 1, thereby reducing the load on the supercharger 1 from external power sources and alleviating the strain on the urban power distribution network. Furthermore, the supercharger can be deployed modularly, saving land area and shortening the on-site construction period, thus addressing the problem of scarce urban land resources and the difficulty of retrofitting existing facilities.

[0077] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
