[0007] Preferably, the rear panel of the battery module is provided with positioning holes, and the inner surface of the rear cover plate of the cabinet is provided with a number of positioning pins that correspond one-to-one with the positioning holes on each battery module to cooperate with the positioning holes to achieve hot-swap connection, precise positioning, and improve the stability of the battery module in the cabinet.

[0008] Preferably, the front panels of the battery module and the high-voltage control box are connected to the cabinet by screws.

[0009] Preferably, the outer surface of the rear panel of the battery module is provided with two cooling fans located on both sides of the battery hot-swappable connector socket.

[0010] Preferably, the rear cover of the cabinet has heat dissipation holes, and the upper cover of the cabinet has cable entry holes.

[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A hot-swappable energy storage system, combined with Figure 1As shown, it includes a cabinet 1, a high-voltage control box 2, and several battery modules 3. The cabinet 1 has an open front structure. The high-voltage control box 2 and several battery modules 3 are arranged inside the cabinet 1 and arranged sequentially from top to bottom. The high-voltage control box 2 and several battery modules 3 are all hot-swappable connected to the cabinet 1 and the hot-swappable connection is achieved through the cabinet 1.

[0021] like Figures 4 to 5 As shown, a battery hot-swappable connector female socket 31 is provided on the outer surface of the rear panel of the battery module 3, and the signal lines and power lines inside the battery module 3 are connected to the battery hot-swappable connector female socket 31.

[0022] The high-voltage control box 2 has a hot-swappable male connector 21 on the outer surface of its rear panel. The signal lines and power lines inside the high-voltage control box 2 are connected to the hot-swappable male connector 21.

[0023] like Figure 3 As shown, the inner surface of the rear panel of cabinet 1 is provided with a cabinet hot-swappable connector female socket 11 and several cabinet hot-swappable connector male sockets 12. The cabinet hot-swappable connector female socket 11 is used for hot-swappable connection with the control box hot-swappable connection male socket 21, thereby realizing hot-swappable connection between the high-voltage control box 2 and cabinet 1. Several cabinet hot-swappable connector male sockets 12 are electrically connected to the cabinet hot-swappable connector female socket 11 and are located below the cabinet hot-swappable connector female socket 11 and arranged sequentially from top to bottom. The cabinet hot-swappable connector male sockets 12 are used for hot-swappable connection with the battery hot-swappable connector female socket 31, thereby realizing hot-swappable connection between the battery module 3 and cabinet 1, and further realizing hot-swappable connection between the battery module 3 and high-voltage control box 2. This not only solves the problems of poor aesthetics and complicated operation of replacing battery module 3 in the existing front wiring form of energy storage battery cabinets, but also realizes convenient plugging and unplugging and quick replacement of battery module 3, and improves the overall aesthetics and connection reliability of the cabinet.

[0024] The rear end of the battery module 3 has a positioning hole 33. The inner surface of the rear cover plate of the cabinet 1 is provided with several sets of positioning pins 13 that correspond one-to-one with the positioning holes 33 on each battery module 3. Through the cooperation of the positioning pins 13 and the positioning holes 33, the hot-swap positioning of the battery module 3 can be more accurate, and the rear end of the battery module 3 can be more firmly fixed. In addition, the front panels of the battery module 3 and the high-voltage control box 2 are respectively connected to the cabinet 1 with screws, which can reduce the loosening of the connection between the battery module 3 and the high-voltage control box 2 and the cabinet 1 caused by external vibration or shaking and other factors.

[0025] Two cooling fans 32 are located on either side of the battery hot-swappable connector socket 31 on the outer surface of the rear panel of the battery module 3. Figure 2As shown, the rear cover plate of the cabinet 1 has heat dissipation holes 14, which facilitates the heat dissipation of the battery module 3 and the high voltage control box 2; the upper cover plate of the cabinet 1 has a cable inlet hole 15, which facilitates the connection of the cable to the high voltage control box 2.

[0026] When using this utility model, if it is necessary to replace the battery module 3, simply pull the battery module 3 to be replaced out of the cabinet 1 and then insert the new battery module 3. The operation is simple and convenient, without the need for complicated wire disconnection and wiring operations.
