[0022] Please see Figure 1-4 As shown, a battery distribution box of this utility model includes a quick-connect connector 1, a shunt 2, a top cover 3, a copper busbar 4, a relay 5, a fuse 6, and a base 7. The top cover 3 is installed on the top of the base 7. The quick-connect connector 1 and the relay 5 are both fixed to the base 7 with bolts. The relay 5 can control the opening and closing of the power supply. The copper busbar 4 is connected to the load end of the relay 5. The shunt 2 and the fuse 6 are both connected to the copper busbar 4 and fixed with bolts. The fuse 6 can protect the equipment from being burned by abnormal current. The shunt 2 collects the current data of the negative terminal and transmits it to the battery management system of the battery pack through the quick-connect connector 1.

[0027] The working principle of this utility model is as follows:

[0028] In use, all electrical components can be mounted on the base 7. During installation, the battery distribution box is installed in the battery pack with screws. The positive power supply starts from the battery input and is split into two paths through the main circuit fuse: one path goes to the heating fuse, and the other path goes through the main positive relay to the positive terminals of the fast charging input and discharge output. The negative power supply starts from the battery input and is split into two paths through the shunt 2: one path goes to the heating output, and the other path goes through the main negative relay to the negative terminals of the fast charging input and discharge output. The perforated top cover 3 allows for centralized arrangement of all electrical components and external connection points, thereby improving the integration of the distribution box, reducing assembly complexity, and minimizing the risk of failure. The relay 5 controls the power supply switching, and the fuse 6 protects the equipment from being burned by abnormal current. The shunt 2 collects the negative current data and transmits it to the battery management system of the battery pack through the quick-connect connector 1.
