Description

Technical Field

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

[0002] With the continuous development of the energy storage and charging industry, the power demand for charging products is increasing, and the impact on grid capacity is also gradually rising. At present, the energy storage and charging modules on the market are not effective in dealing with large-scale and centralized grid impacts. Most of them can only work according to the preset energy storage and charging mode, and cannot effectively cope with the changing charging scenarios, so their adaptability is not good enough. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a highly flexible and adaptable energy storage and charging system that can effectively cope with changing charging scenarios.

[0005] The contact assembly includes multiple openable and closable output contactors and multiple openable and closable parallel contactors;

[0006] The charging module is configured as a plurality of such modules, and any two of the charging modules are connected by a plurality of such parallel contactors;

[0007] An energy storage module is provided, and each of the energy storage modules is connected to at least two of the charging modules through a plurality of the parallel contactors;

[0008] There are multiple charging guns, each of which is connected to one of the charging modules via one of the output contactors.

[0009] Optionally, in one embodiment of this utility model, the number of the charging gun and the charging module is both set to N, and the number of the energy storage module is set to N-1, where N is a positive integer not less than 2.

[0015] This invention proposes a charging and energy storage system that integrates a contact assembly, multiple charging modules, multiple energy storage modules, and multiple charging guns to provide a more integrated and rationally configured system.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] Figure 1 This is a schematic diagram of the structure of a storage and charging system provided in an embodiment of the present invention. Figure 1 As shown, the storage and charging system includes, but is not limited to:

[0021] The contact assembly includes multiple openable and closable output contactors 500 and multiple openable and closable parallel contactors 400. The engagement and disengagement control of the output contactors 500 and parallel contactors 400 can be performed in the background, for example, by those skilled in the art based on relevant models or modules. This part is well known to those skilled in the art and will not be described in detail. The specific number of output contactors 500 and parallel contactors 400 can be set according to the actual needs of the scenario, and there is no limitation here.

[0022] There are multiple charging modules 100, and any two charging modules 100 are connected through several parallel contactors 400.

[0023] An energy storage module 200 is provided, and each energy storage module 200 is connected to at least two charging modules 100 through a plurality of parallel contactors 400;

[0024] There are multiple charging guns 300, and each charging gun 300 is connected to one of the charging modules 100 through one of the output contactors 500.

[0025] As can be seen, by setting up an integrated contact component, multiple charging modules 100, multiple energy storage modules 200, and multiple charging guns 300, a more integrated and rationally configured charging and storage system is provided. In particular, any two charging modules 100 are connected through several parallel contactors 400 to ensure flexible power dispatching among the charging modules 100. Each energy storage module 200 is connected to at least two charging modules 100 through several parallel contactors 400 to ensure that the energy storage module 200 can simultaneously charge and store energy with multiple charging modules 100 to meet diverse charging needs. Furthermore, each charging gun 300 is connected to one of the charging modules 100 through one of the output contactors 500 to ensure that each charging gun 300 can perform stable charging. Compared with related existing technologies, the overall system design is highly flexible and adaptable, and can more effectively cope with changing charging scenarios to meet users' charging needs.

[0026] In one embodiment, such as Figure 2As shown, the energy storage and charging system may also include, but is not limited to, an energy distribution module 600 connected to each energy storage module 200 and each charging module 100 respectively. The energy distribution module 600 is used to activate each energy storage module 200 to supply power during peak electricity price periods and to activate each charging module 100 to supply power during off-peak electricity price periods. It can be seen that if the current period is a peak electricity price period, the energy storage module 200 will be used first to charge the vehicle. Conversely, if the current period is an off-peak electricity price period, the charging module 100 will be used first to charge the vehicle. At this time, the unused charging module 100 can be allocated to the energy storage module 200 for replenishment. Overall, this can improve resource utilization efficiency and reduce resource consumption.

[0027] In one embodiment, the energy storage modules 200 can call each other to achieve flexible energy scheduling. Since the charging modules 100 can be interconnected, any charging module 100 in an idle state can directly charge the energy storage module 200 to further improve resource utilization efficiency.

[0028] In one embodiment, the energy storage and charging system may be configured as a host side and a terminal side, with the host side and the terminal side serving as opposite sides to enable configuration differentiation of the energy storage and charging system. In this embodiment, all charging modules 100, all energy storage modules 200, and all parallel contactors 400 are located on the host side to facilitate convenient scheduling of the charging modules 100 and energy storage modules 200. In this embodiment, all charging guns 300 and all output contactors 500 are located on the terminal side to ensure that the charging guns 300 can conveniently supply power to the vehicle through the terminal.

[0029] In one embodiment, the charging and energy storage system may include, but is not limited to, charging cabinets and energy storage cabinets that are independently configured. All charging modules 100 are housed in the charging cabinets, and all energy storage modules 200 are housed in the energy storage cabinets. That is, the charging cabinets and energy storage cabinets are two different independent cabinets. By housing the charging modules 100 and energy storage modules 200 inside each cabinet, it is ensured that the operation of the charging modules 100 and energy storage modules 200 is not easily affected, thereby improving the operational stability of the charging modules 100 and energy storage modules 200 and reducing interference that may be caused by environmental factors.

[0030] In one embodiment, the number of charging guns 300 and charging modules 100 is set to N, and the number of energy storage modules 200 is set to N-1, where N is a positive integer not less than 2. Preferably, N can be, but is not limited to, a value of 6.

[0031] To better illustrate the working principle of the above embodiments, the following detailed explanation is provided with specific examples.

[0032] like Figure 3As shown, there are 5 energy storage modules, 6 charging modules and 6 charging guns. K1 to K21 are the positive parallel contactors of the charging host, and KZ1 to KZ6 are the terminal output positive contactors.

[0033] Taking a single charging gun with an actual charging power of 80kW as an example, insert the charging gun into the vehicle's charging port and close the KZ1 output contactor to perform hierarchical scheduling. Specifically, the first layer directly calls the No. 1 charging module.

[0034] Second layer: When K6 is attracted, it calls the No. 6 charging module; when K1 is attracted, it calls the No. 2 charging module; when K8 is attracted, it calls the No. 4 charging module; when K11 is attracted, it calls the No. 1 energy storage module.

[0035] Third layer: Connecting K12 or K3 activates charging module 3, connecting K5 or K4 activates charging module 5, and connecting K12 activates energy storage module 2. At this point, all charging modules have been activated.

[0036] Fourth layer: Activate K20 and K18 or K19 and K18 to call energy storage module 4; activate K13 and K15 or K14 and K15 to call energy storage module 3.

[0037] Fifth layer: K20 or K21 is activated to call energy storage module No. 5. At this point, all energy storage modules have been activated, and the charging gun will call different energy storage modules.

[0038] Charging with other charging guns is similar to the process with the 1-gun charging. The number of charging modules and energy storage devices called up depends on the actual needs of the vehicle and can be flexibly allocated based on the topology given in the example above.

[0039] Taking replenishing power to energy storage module 1 as an example, engaging contactor K11 replenishes power to energy storage module 1 via charging module 1; engaging K20 / K19 calls charging module 6 to replenish power to energy storage module 1; engaging K11 / K6 calls charging modules 1 / 6 to replenish power to energy storage module 1; engaging K11 / K1 calls charging modules 1 / 2 to replenish power to energy storage module 1; engaging K20 / K19 / K7 calls charging modules 6 / 3 to replenish power to energy storage module 1; engaging K11 / K1 / K2 calls charging modules 1 / 2 / 3 to replenish power to energy storage module 1; engaging K20 / K19 / K5 calls charging modules 6 / 5 to replenish power to energy storage module 1; engaging K20 / K19 / K5 / K4 calls charging modules 6 / 5 / 4 to replenish power to energy storage module 1. It can be seen that at least 4 sets of contactors need to be engaged to charge the energy storage module and call all charging modules.

[0040] It is understandable that the above example uses 6 charging modules / charging guns and 5 energy storage modules as an example, but it is not the only limitation. Modules or charging lines can be added or removed on this basis, and similar expansions can be made.

[0041] In summary, this utility model embodiment provides a more integrated and rationally configured energy storage and charging system by setting up an integrated contact component, multiple charging modules, multiple energy storage modules, and multiple charging guns. The overall system design is highly flexible and adaptable, and can more effectively cope with changing charging scenarios and meet users' charging needs.
