The main function of the battery module is to connect multiple battery cells together to increase the voltage and energy storage capacity of the battery system. By connecting the battery cells in parallel or in series, the battery module can meet the electrical energy requirements of different applications. Connecting the battery cells in series can increase the total voltage, while connecting the battery cells in parallel can increase the total capacity. The battery module usually carries a power supply and distribution system, which is responsible for monitoring and managing the charging and discharging process of the battery to ensure the safety and stable performance of the battery.

[0003] However, there are still some deficiencies in the current battery module. For example, the existing battery module will generate heat during use, and the long-term heat generation affects the battery usage condition and is also prone to safety hazards.

The heat dissipation component for preventing high temperature of the battery is arranged outside the battery cell group, and the heat dissipation component includes a mounting frame, a buffer cushion strip, a heat dissipation port, a heat dissipation fan, a side plate frame and an air inlet. And a buffer cushion strip is arranged on the outer side of the end of the mounting frame, and heat dissipation ports are opened on the surface of the mounting frame. At the same time, a heat dissipation fan is arranged outside the heat dissipation port. The outer side of the buffer cushion strip is connected with the side plate frame, and air inlets are opened on the surface of the side plate frame.

[0022] The following further describes the implementation mode of the present utility model in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figure 1 and Figure 2 shown, a battery module and a power supply and distribution system include a battery cell group 1 and a heat dissipation component 3. An end plate 2 is provided at the end of the battery cell group 1. The heat dissipation component 3 for preventing the battery from overheating is arranged outside the battery cell group 1. The heat dissipation component 3 includes a mounting frame 301, a buffer cushion strip 302, a heat dissipation port 303, a heat dissipation fan 304, a side plate frame 305 and an air inlet 306. A buffer cushion strip 302 is arranged on the outer side of the end of the mounting frame 301. The shape of the mounting frame 301 is a U-shaped. The mounting frame 301 and the side plate frame 305 form a double-layer side shell outside the battery cell group 1, and the inside is hollow to provide an installation space for the heat dissipation fan 304. The mounting frame 301 and the heat dissipation port 303 are of an integrated structure. And two buffer cushion strips 302 are symmetrically arranged about the central axis of the mounting frame 301. The buffer cushion strip 302 plays a role of support and force buffering on the inner sides of the mounting frame 301 and the side plate frame 305, so that when an external force directly acts on the side plate frame 305, it can be buffered to avoid direct damage to the battery cell group 1. Moreover, heat dissipation ports 303 are formed on the surface of the mounting frame 301. At the same time, a heat dissipation fan 304 is arranged outside the heat dissipation port 303. The heat dissipation fan 304 rotates to continuously cool and dissipate heat from the battery cell group 1 through the heat dissipation port 303. The outer side of the buffer cushion strip 302 is connected to the side plate frame 305. An air inlet 306 is formed on the surface of the side plate frame 305. The air inlet 306 provides an air intake and heat dissipation space for the heat dissipation fan 304. A connection block 4 is arranged on the side of the end plate 2. The battery BMU 5 is connected to the upper end of the battery cell group 1.

[0024] As Figure 3 and Figure 4As shown in the figure, an upper cover 6 is provided at the upper end of the battery BMU5, and an electrical interface 7 is provided on the surface of the upper cover 6. A fixing bracket 8 is provided at the end of the upper cover 6. The fixing bracket 8 is installed on the upper cover 6 and the side plate frame 305 under the action of screws for the installation and fixation of the upper cover 6 and the side plate frame 305. A fixing bolt 9 is provided at the end of the fixing bracket 8. The shape of the fixing bracket 8 is in the shape of a "匚", and two fixing brackets 8 are symmetrically arranged about the central axis of the upper cover 6. A protection component 10 for dust and block prevention is provided on the side of the side plate frame 305. The number of the protection components 10 is symmetrically arranged in two groups about the central axis of the side plate frame 305. The protection component 10 includes a protection net 1001 and a block prevention frame 1002. The protection net 1001 plays a role in dust prevention in the air inlet 306, and the block prevention frame 1002撑出空间 outside the air inlet 306 to prevent the air inlet 306 from being blocked after the battery module is installed, which affects the heat dissipation effect. The protection net 1001 is provided with the block prevention frame 1002 on the outside, and at the same time, the block prevention frame 1002 further increases the anti-collision and buffering space on the side of the side plate frame 305.

[0025] In summary, for the battery module and the power supply and distribution system, first, according to Figures 1 to 4 the structure shown in the figure, the mounting frame 301 and the side plate frame 305 form a double-layer side shell outside the battery cell group 1. The battery cell group 1 is installed inside the mounting frame 301, and the battery cell group 1 is externally wrapped by cooperating with the end plate 2 and the upper cover 6, etc. Then, the fixing bracket 8 is installed on the upper cover 6 and the side plate frame 305 under the action of screws for the installation and fixation of the upper cover 6 and the side plate frame 305. At this time, the buffer cushion strip 302 plays a role of support and force buffering on the inner sides of the mounting frame 301 and the side plate frame 305, so that when an external force directly acts on the side plate frame 305, it can be buffered to prevent the battery cell group 1 from being directly damaged. The battery BMU5 mainly consists of a battery sampling management chip, a main processor CPU, a battery peripheral power supply supplement and charging circuit, and a peripheral protection and filtering circuit. During power supply and distribution, voltage monitoring, current detection, temperature monitoring, insulation monitoring, relay status monitoring, etc. are carried out on the battery module. When the battery cell group 1 generates heat during use, the cooling fan 304 starts to rotate and continuously cools and dissipates heat from the battery cell group 1 through the heat dissipation port 303. When inhaling air, the protection net 1001 plays a role of dust prevention in the air inlet 306. After the battery module is installed, the block prevention frame 1002 can prevent the air inlet 306 from being blocked after the battery module is installed, which affects the heat dissipation effect.
