[0061] See also Figure 1 , Figure 2 , Figure 3 and Figure 4. The present application provides a charging cabinet 1. The charging cabinet 1 includes a shell 11, a charging module 12, a first switch control module 13 and a second switch control module 14. The shell 11 includes a shell body 111 and a partition plate 112, the shell body 111 is surrounded to form a receiving space 113, and the partition plate 112 divides the receiving space 113 into a plurality of sub-receiving spaces 114. The charging module 12 is received in one of the plurality of sub-receiving spaces 114, one end of the charging module 12 receives an alternating first electrical signal, and the charging module 12 is used to convert the alternating first electrical signal into a direct second electrical signal and output it through the other end. The first switch control module 13 is received in another of the plurality of sub-receiving spaces 114, and one end of the first switch control module 13 is electrically connected to the charging module 12. The second switch control module 14 is received in another of the plurality of sub-receiving spaces 114, and one end of the second switch control module 14 is electrically connected to the charging module 12 and the first switch control module 13. The second electrical signal is outputted via one of the first switch control module 13 and the second switch control module 14 , or the first switch control module 13 receives the third electrical signal outputted by the energy storage system 2 and outputs it to the electrical device 3 via the second switch control module 14 .

[0062] Specifically, the charging cabinet 1 can be used for, but is not limited to, charging electric vehicles, energy storage systems 2, or other devices to be charged.

[0063] Optionally, the charging cabinet 1 is a DC charging cabinet 1. It is understandable that the traditional AC charging cabinet directly provides AC power from the power grid to the charger of the electric vehicle. Since the chargers of most electric vehicles have low power, the power of the AC charging cabinet is generally low. Compared with the AC charging cabinet, the DC charging cabinet 1 provided in this embodiment can directly charge the battery pack of the electric vehicle and can provide a high-power charging mode for the electric vehicle, thereby greatly shortening the charging time of the electric vehicle.

[0064] Optionally, the charging cabinet 1 further includes a main control module 127 and an AC input control module 17. The receiving space 113 formed by the shell body 111 is used to receive the charging module 12, the first switch control module 13, the second switch control module 14, the main control module 127, the AC input control module 17 and other functional components of the charging cabinet 1. Furthermore, the partition plate 112 is fixedly connected to the shell body 111 and is used to separate the charging module 12, the first switch control module 13, the second switch control module 14, the main control module 127 and the AC input control module 17.

[0065] In this embodiment, the charging module 12, the first switch 131 module and the second switch control module 14 are respectively contained in different sub-containment spaces 114 and separated by the partition plate 112, so that each module is relatively independently arranged. When it is necessary to expand the capacity or function of the charging cabinet 1, it is only necessary to simply increase the number of corresponding modules without large-scale transformation of the entire system. In addition, each module can be compactly arranged in the cabinet to maximize the use of the internal space of the cabinet. Since each module is installed independently, it can be flexibly laid out according to actual needs to further optimize the space utilization efficiency. At the same time, since a module can be inspected or replaced separately without affecting other modules, the maintenance of the charging cabinet 1 becomes more convenient.

[0066] Preferably, the charging cabinet 1 can be electrically connected to the electric vehicle to charge it, and the charging cabinet 1 is also electrically connected to the energy storage system 2, the charging cabinet 1 can charge the energy storage system 2, and the energy storage system 2 can also charge the electric vehicle through the charging cabinet 1. It can be understood that since the high-power charging cabinet 1 has a large power supply requirement, many small and medium-sized units or some residential areas will have insufficient power supply capacity, and the charging cabinet 1 with the energy storage system 2 can expand the power supply capacity in a low-cost manner, thereby meeting the fast charging needs of electric vehicles.

[0067] Optionally, the energy storage system 2 is provided for the external environment of the charging cabinet 1, or is configured by the charging cabinet 1 itself. In this embodiment, the energy storage system 2 is provided for the external environment as an example for illustration.

[0068] Optionally, the charging module 12 is electrically connected to the energy storage system 2 through the first switch control module 13, and the charging module 12 is electrically connected to the electric device 3 through the second switch control module 14, and the electric device 3 is an electric vehicle. And the end of the second switch control module 14 away from the electric vehicle is also electrically connected to the energy storage system 2. In other words, one end of the first switch control module 13 is electrically connected to the charging module 12 and the second switch control module 14, and the other end of the first switch control module 13 is electrically connected to the energy storage system 2. One end of the second switch control module 14 is electrically connected to the charging module 12 and the first switch control module 13, and the other end of the second switch control module 14 is electrically connected to the electric vehicle.

[0069] Furthermore, the charging cabinet 1 has a first mode, a second mode and a third mode. When the charging cabinet 1 is in the first mode, the second electrical signal output by the charging module 12 is output to the energy storage system 2 via the first switch control module 13. When the charging cabinet 1 is in the second mode, the second electrical signal is output via the second switch control module 14 and output to the electric vehicle. When the charging cabinet 1 is in the third mode, the energy storage system 2 outputs a third electrical signal, and the first switch control module 13 receives the third electrical signal and outputs it to the electric vehicle via the second switch control module 14.

[0070] In summary, the charging cabinet 1 provided in this embodiment is provided by placing the charging module 12, the first switch 131 module and the second switch control module 14 in independent sub-accommodation spaces 114 respectively, and isolating them with a partition plate 112, so that each module is relatively independently arranged, so as to facilitate the maintenance and expansion of the charging cabinet 1. The charging cabinet 1 can conveniently increase or decrease the number of each module according to actual needs, so as to adapt to charging needs of different scales. In addition, the charging cabinet 1 can be connected to the energy storage system 2 and charge the energy storage system 2, and the energy storage system 2 can charge the electric vehicle through the charging cabinet 1, thereby realizing a low-cost expansion of the power supply capacity of the charging cabinet 1. In addition, the charging cabinet 1 simplifies the circuit layout of each module through the internal modular design, reduces the risk of failure that may be caused by complex circuit connections, and improves the space utilization efficiency of the charging cabinet 1. Therefore, the charging cabinet 1 can adaptably meet the charging needs of electric vehicles while also having higher safety and reliability, thereby providing a safer and more reliable charging solution for electric vehicles, and the charging cabinet 1 is smaller in size, so that it can be applied to a wider range of application scenarios.

[0071] See also Figure 4 , Figure 5 , Figure 6 and Figure 7The charging cabinet 1 further includes a third switch 15, one end of which is connected to the charging module 12, and the other end of which is electrically connected to the first switch control module 13 and the second switch control module 14. The third switch 15 has an on state and a off state, and the first switch control module 13 has an on state and a off state, and the second switch control module 14 has an on state and a off state. Wherein, when the third switch 15 is in an on state, the first switch control module 13 is in an on state, and the second switch control module 14 is in a off state, the second electrical signal is output via the first switch control module 13. When the third switch 15 is in an on state, the first switch control module 13 is in a off state, and the second switch control module 14 is in an on state, the second electrical signal is output via the second switch control module 14. When the third switch 15 is in a off state, the first switch control module 13 is in an on state, and the second switch control module 14 is in an on state, the first switch control module 13 receives the third electrical signal and outputs it to the power-consuming device 3 via the second switch control module 14.

[0072] Optionally, one end of the first switch control module 13 is electrically connected to the third switch 15 and the second switch control module 14, and the other end of the first switch control module 13 can be electrically connected to the energy storage system 2. One end of the second switch control module 14 is electrically connected to the third switch 15 and the first switch control module 13, and the other end of the second switch control module 14 can be electrically connected to the electric vehicle.

[0073] Among them, when the charging cabinet 1 is in the first mode, the third switch 15 is in the on state, the first switch control module 13 is in the on state and the second switch control module 14 is in the off state, the second electrical signal output by the charging module 12 is output to the energy storage system 2 via the first switch control module 13, and charges the energy storage system 2.

[0074] Furthermore, when the charging cabinet 1 is in the second mode, the third switch 15 is in the on state, the first switch control module 13 is in the off state and the second switch 141 is in the on state, the third electrical signal output by the charging module 12 is output to the electrical equipment 3, that is, to the electric vehicle, via the second switch control module 14, and charges the electric vehicle.

[0075] Furthermore, when the charging cabinet 1 is in the third mode, the third switch 15 is in a closed state, the first switch control module 13 is in an open state, and the second switch 141 is in an open state, the energy storage system 2 outputs a third electrical signal, and the third electrical signal passes through the first switch control module 13 and the second switch control module 14 in sequence, and is output to the electric vehicle to charge it.

[0076] Optionally, the first switch control module 13 includes a first switch 131, and the first switch 131 is composed of a relay. It should be noted that the first switch control module 13 is in an on state, which can be understood as the relay is in an electrically connected state. The first switch control module 13 is in a closed state, which can be understood as the relay is in a disconnected state.

[0077] Optionally, the second switch 141 control includes a second switch 141, and the second switch 141 is a relay. It should be noted that the second switch control module 14 is in an on state, which can be understood as the relay is in an electrically connected state.

[0078] Optionally, the third switch 15 is a relay. It should be noted that the third switch 15 is in an on state, which can be understood as the relay being in an electrically connected state. The third switch 15 is in a closed state, which can be understood as the relay being in a disconnected state.

[0079] In this embodiment, the energy storage system 2 can charge the electric vehicle via the first switch control module 13 and the second switch control module 14. It can be understood that since the high-power charging cabinet 1 has a large power supply requirement, many small and medium-sized units or some residential areas will have insufficient power supply capacity. The charging cabinet 1 provided in this embodiment can be electrically connected to the energy storage system 2, thereby reducing the dependence of the charging cabinet 1 on the external power supply system. In addition, the charging cabinet 1 can also achieve efficient energy utilization by intelligently managing the energy storage system 2 through the first switch control module 13. For example, during periods of low electricity consumption, the charging cabinet 1 can store excess electrical energy through the energy storage system 2, and during peak electricity consumption or when charging electric vehicles is required, the energy storage system 2 can release the stored energy to meet the charging needs of electric vehicles, thereby making the charging cabinet 1 highly flexible.

[0080] See also Figure 4The charging cabinet 1 includes a plurality of charging modules 12, a plurality of the first switch control modules 13 and a plurality of the second switch control modules 14, each charging module 12 is electrically connected to a different first switch control module 13, and each charging module 12 is electrically connected to a different second switch control module 14, the plurality of first switch control modules 13 can be electrically connected to different interfaces of the energy storage system 2, and the plurality of second switch control modules 14 can be electrically connected to different electrical devices 3.

[0081] In the terminology of the present application, "plurality" means greater than or equal to two, and can be two, three, four or five, etc.

[0082] Optionally, the number of the charging modules 12 is equal to the number of the first switch control modules 13, and the number of the charging modules 12 is equal to the number of the second switch control modules 14. The charging modules 12 and the first switch control modules 13 are arranged in a one-to-one correspondence, that is, each charging module 12 is electrically connected to a different first switch control module 13. And the charging modules 12 and the second switch control modules 14 are arranged in a one-to-one pair, that is, each charging module 12 is electrically connected to a different second switch control module 14.

[0083] Furthermore, the energy storage system 2 has multiple interfaces, and the multiple first switch control modules 13 can be electrically connected to different interfaces of the energy storage system 2, that is, the first switch control modules 13 can be set in a one-to-one correspondence with the interfaces of the energy storage system 2. The multiple second switch control modules 14 can be electrically connected to different electrical equipment 3, which can be understood as the multiple second switch control modules 14 can be electrically connected to multiple electric vehicles, and each of the second switch control modules 14 can be set in a one-to-one correspondence with an electric vehicle.

[0084] In this embodiment, the multiple charging modules 12 of the charging cabinet 1 can work simultaneously, and the multiple charging modules 12 can also transmit the second electrical signal to different electric vehicles respectively, so as to realize the simultaneous charging of multiple electric vehicles. In addition, the energy storage system 2 also charges multiple electric vehicles through its multiple interfaces, thereby further improving the working efficiency of the charging cabinet 1. When there are a large number of electric vehicles or the charging demand is large, the energy storage system 2 can serve as a supplementary power source and work in conjunction with the charging module 12 to jointly meet the charging needs of multiple electric vehicles. The charging cabinet 1 can meet the common needs of charging multiple vehicles at the same time in electric vehicle charging stations, effectively avoiding the problem of long charging waiting time, thereby improving the working efficiency and user experience of the charging cabinet 1.

The second switch control module 14 further includes a second connector 145, and the second switch 141 is electrically connected to the charging module 12 and the first switch control module 13 through the second connector 145.

Specifically, different electric devices 3 may have different requirements for charging power. For example, some electric devices 3 may need to be charged quickly to save time, while some electric devices 3 may need to be charged at a lower power to ensure safety. The charging cabinet 1 can meet different charging needs and ensure the safety and efficiency of the charging process through the control of the power distribution module 16. Therefore, through the control of the power distribution module 16 and the selection of multiple power modes, the versatility of the charging cabinet 1 can be significantly improved, so that a single charging cabinet 1 can meet the charging concept requirements of family cars, commercial vehicles, or many other types of electric vehicles, thereby reducing the overall construction cost and maintenance cost of the charging cabinet 1 in actual application.
