[0023] Please see Figures 1 to 5 The present invention provides a wireless battery cabinet. The wireless battery cabinet includes a cabinet body, battery packs, busbar units, and connectors. Multiple battery packs are arranged sequentially within the cabinet body along its height. Each battery pack includes two battery modules 1 spaced apart along the length of the cabinet body, with the two battery modules 1 being symmetrical and forming a wiring space between them. The busbar unit is longitudinally positioned within the wiring space, and the connectors are used to connect the battery packs and the busbar unit.

[0024] The present invention provides a wireless battery cabinet. Compared with the prior art, it sets the battery pack into two battery modules 1, forming a half-modular design. A wiring space is formed between the two battery modules 1. Busbar units and connectors are designed in the wiring space. The connectors are connected to the battery modules 1 on both sides, realizing the wireless design in the battery cabinet. This avoids too many messy wires inside the battery and facilitates battery maintenance and replacement.

[0025] Two battery modules 1 of the same battery pack are symmetrically arranged, with their connectors facing each other and both pointing into the wiring space. Connectors are located within the wiring space. The connectors include a positive connector and a negative connector. The positive connector connects the positive terminals of the two battery modules 1 in series; the negative connector connects the negative terminals of the two battery modules 1 in series.

[0026] Furthermore, the semi-modular design divides the original single battery module 1 into two battery modules 1, reducing the weight of a single battery module 1 to half, which facilitates handling by on-site installation and maintenance personnel. The semi-modular design also makes full use of the front and rear depth space of the cabinet, avoiding wasted space at the rear of the cabinet, resulting in high cabinet height, large space utilization, and a centrally located center of gravity, which is beneficial for packaging and transportation. This design is suitable for cabinets with depths of 1000mm, 1200mm, and 1400mm.

[0027] In some possible embodiments, please refer to Figures 4 to 5 The busbar unit includes two busbar modules 3, which are spaced apart in the wiring space along the width of the cabinet; the connector is located between the two busbar modules 3.

[0028] The busbar unit within the wireless battery cabinet comprises two spaced-apart busbar modules 3: a positive busbar module 3 and a negative busbar module 3. These modules are spaced apart along the width of the cabinet within the cabling space, with connectors located between them. The combination of the busbar unit and connectors enables a wireless design within the cabinet. The positive and negative busbar modules 3 are positioned on either side of the cabling space in the center of the cabinet, ensuring sufficient safety clearance. Furthermore, after installation, the busbar unit is concealed within the battery modules 1 on either side, providing good safety protection and a high degree of overall aesthetics and consistency.

[0029] Specifically, the positive electrode connector connects to the positive terminals of the two battery modules 1 in the same battery pack and extends to the positive electrode busbar module 3; the positive electrode connector connects to the negative terminals of the two battery modules 1 in the same battery pack and extends to the negative electrode busbar module 3.

[0030] The multiple battery packs inside the cabinet are arranged longitudinally at intervals and form a parallel structure, with each battery pack connected to the same busbar unit. That is, the positive terminal connector of each battery pack extends to the same positive terminal busbar module 3, and the negative terminal connector of each battery pack extends to the same negative terminal busbar module 3.

[0031] The positive and negative terminals have the same structure.

[0032] In some possible embodiments, please refer to Figure 4 and Figure 5 The connector includes a connector body and an extension terminal.

[0035] Specifically, taking the positive terminal connector as an example, the connecting end of the positive terminal connector is connected to the positive busbar module 3, and its insulating end 11 extends to a distance from the negative busbar module 3. An insulating fixing member 8 is provided between the insulating end 11 and the negative busbar module 3.

[0036] Both the connecting end and the insulating end 11 are parallel to the busbar module 3. The connecting end is snapped into or fixed to the busbar module 3 with screws. The insulating fixing part 8 of the insulating end 11 is a block structure. The two end faces of the block structure are respectively attached to the side wall of the insulating end 11 and the side wall of the busbar module 3. There are connecting holes extending inward on both end faces of the block structure, and the two connecting holes are not connected. During installation, one end of the block structure is connected to the insulating end 11 and the other end is connected to the busbar module 3 using nails, so that the insulating end 11 is fixedly connected to the busbar terminal while avoiding conductivity.

[0037] The insulating fastener 8 can be made of insulating rubber block or ceramic insulating material.

[0038] In some possible embodiments, please refer to Figure 4 and Figure 5 The connector body includes two battery connection parts 7, which are arranged in parallel and are used to connect two battery modules 1 of the same battery pack.
