Through the setting of the limiting components, the limiting components composed of the side guard plates 200 and the limiting hoops 201 form a three-dimensional constraint structure, which can quickly and neatly align the multiple sets of batteries 100 without complex support processes. At the same time, the side guard plates 200 restrict the lateral displacement of the batteries 100, and the limiting hoops 201 tighten the integrated shape of the upper and lower surfaces, effectively preventing the individual batteries 100 from loosening, misaligning, colliding and shaking during driving, while reducing physical friction between the batteries 100 and reducing local heat generation caused by friction.

[0042] The enclosure includes a U-shaped plate 301, with side plates 300 snapped onto both sides of the U-shaped plate 301. Connecting screws 305 are inserted into the front and rear surfaces of the U-shaped plate 301 and at corresponding positions at the ends of each set of side plates 300. The ends of each set of connecting screws 305 pass through the corresponding side U-shaped plate 301 and are threaded to the corresponding side end surface of the side plate 300. Through the enclosure structure, which uses the U-shaped plate 301 and side plates 300 snapped together with the connecting screws 305, quick pre-assembly is achieved through snapping, and the structural fastness is enhanced by the threaded screws, forming a well-sized closed cavity.

[0043] The detachable component includes a fixing bolt 303 inserted into the outer peripheral surface of the top cover 302. The top cover 302 covers the cavity opening formed by the U-shaped plate 301 and the side plate 300.

The two sets of limiting brackets 207 are fixedly installed on the bottom inner walls of both sides of the U-shaped plate 301 and located at the bottom of each side guard plate 200.

The end of each set of connecting bolts 205 penetrates downward through the corresponding side guard plate 200 and can be threaded to the surface of the corresponding side limiting bracket 207. Through the setting of the positioning component, the limiting brackets 207 complete the initial positioning of multiple battery 100 by bottom alignment.

[0045] The electrical connector includes an insulating plate 203 covering the top of multiple battery groups 100. The top of the insulating plate 203 has multiple sets of staggered receiving grooves 208. The inner cavity of the receiving groove 208 is provided with a busbar 101 for connecting two adjacent battery groups 100 together.

[0046] A mounting bracket 204 is provided above the insulating plate 203. The corners of the mounting bracket 204 are bent downwards and respectively fitted onto the necks of four sets of connecting bolts 205. A protective plate 206 is fixedly installed on the top of the mounting bracket 204. Multiple batteries 100 are electrically connected to the protective plate 206 through sampling lines. Through the setting of electrical connectors, the insulating plate 203 provides an electrical isolation base.

At the same time, the mounting bracket 204 is fixed by means of the connecting bolts 205, and the protective plate 206 can be mounted without additional connectors. The sampling lines realize the comprehensive collection of battery 100 parameters.

[0047] Multiple busbars 101 are each embedded with a temperature-sensing resistor 102. The multiple temperature-sensing resistors 102 are electrically connected to the signal input terminal of the protection board 206 through wires. By setting the temperature-sensing resistors 102, the temperature-sensing resistors 102 embedded in the top of the busbars 101 can directly monitor the temperature status of the key nodes in series with the battery 100, and transmit the signal to the protection board 206 in real time through wires, so as to realize the rapid detection of temperature abnormalities.

[0048] The electrical interface 403 includes a circuit board 401 disposed on the inner wall surface of one of the side plates 300. The surface of one of the side plates 300 is provided with multiple electrical interfaces 403 of different types for external communication. The signal terminals of the multiple electrical interfaces 403 are electrically connected to the signal terminals of the circuit board 401 through wires. The signal terminals of the circuit board 401 are electrically connected to the signal terminals of the protection board 206 through wires.

[0049] One of the side plates 300 has two sets of terminals 400 on its surface. The two sets of terminals 400 are electrically connected to the positive and negative terminals of multiple batteries 100 connected in series via busbar 101 through wires. Through the setting of electrical interface 403, circuit board 401 integrates communication and power transmission functions.

By providing the insulating pad 103, the insulating pad 103 between adjacent batteries 100 can block the lateral electrical conduction path, avoid the chain risk caused by leakage of a single battery 100, and at the same time buffer the physical friction of the battery group 100 when it is vibrating or changing in temperature, and reduce the mechanical damage to the battery 100 casing.

[0053] In use, multiple battery groups 100 are arranged adjacent to each other. The insulating pad 103 between adjacent batteries 100 can block lateral electrical conduction and physical friction. At the same time, the outer surfaces of the batteries 100 on both sides are attached to the side guard plate 200. The side guard plate 200 and the upper and lower surfaces of the battery 100 are tightened together by the limiting clamp 201 to form a regular core structure of the battery 100 module, realizing the initial limiting of the battery group 100.

[0054] An insulating plate 203 is installed on the top of the battery module 100. A busbar 101 is placed in a staggered receiving groove 208 on its surface. The busbar 101 connects the electrodes of two adjacent battery modules 100 in sequence, so that multiple battery modules 100 form a series circuit and aggregate power output.

[0055] The housing is assembled from a U-shaped plate 301 and two side plates 300. The connecting screws 305 on the front and rear surfaces of the U-shaped plate 301 pass through itself and are screwed into the ends of the side plates 300, so that the housing forms a closed cavity. After the battery 100 module is placed in the housing, the two sets of limiting brackets 207 on the bottom inner wall of the U-shaped plate 301 are aligned with the bottom of the side plates 200 on both sides of the module. The connecting bolts 205 on the front and rear top of the side plates 200 pass downward through the side plates 200 and are screwed into the limiting brackets 207, which fasten the battery 100 module in the housing and prevent displacement due to vibration during use.

[0056] The mounting bracket 204 above the insulating plate 203 is fixed by the bent corner fitting onto the neck of the connecting bolt 205. The protective plate 206 on the top of the mounting bracket 204 is electrically connected to each group of batteries 100 through a sampling line, which can collect parameters such as battery voltage and charge in real time. The temperature sensing resistor 102 embedded on the top of the busbar 101 is connected to the signal input terminal of the protective plate 206 through a wire, and synchronously monitors the temperature status in the series circuit.

[0057] The top cover 302 is fitted onto the opening of the box, and the fixing bolts 303 on the outer periphery pass through the top cover 302 and are screwed into the surfaces of the U-shaped plate 301 and the side plate 300 respectively, so as to realize the detachable connection between the top cover 302 and the box, and form top protection for the battery 100 module inside the box.

[0058] The circuit board 401 on the inner wall of the side panel 300 of the enclosure is electrically connected to multiple sets of interfaces 403 of different models on the surface of the side panel 300. The interfaces 403 can be connected to external communication devices to realize signal interaction between the protection board 206 and the outside. The two sets of terminals 400 on the surface of the side panel 300 are respectively connected to the positive and negative terminals of the series circuit of the battery 100. External charging and discharging equipment is connected to the circuit through the terminals 400 to complete the charging and discharging operation.

[0059] The protective cover 402 on the surface of the terminal 400 can isolate it from contact with foreign objects and prevent accidental short circuits. The protection board 206 monitors the status of the battery 100 module in real time based on the parameters of the battery 100 collected by the sampling line and the temperature signal of the temperature sensing resistor 102. If any abnormality occurs, it can be fed back to the external device through the circuit board 401 and the interface 403 to ensure charging and discharging safety.
