[0014] See attached picture.
[0015] figure 1 is a schematic diagram of the electrical architecture. It can be seen from the figure that the power control unit can complete the following working modes.
[0016] 1. The bodywork battery supplies power to the bodywork load, and the chassis battery supplies power to the chassis load;
[0017] When the vehicle is running and working normally, relays ZJ1, ZJ2, ZJ3 and ZJ4 are closed, relays ZJ5 and ZJ6 are disconnected, the bodywork battery system supplies power to the bodywork load, and the chassis battery system supplies power to the chassis.
[0018] 2. The bodywork battery supplies power to the chassis load, and the chassis battery supplies power to the bodywork load;
[0019] When the vehicle bodywork battery system is out of power and the bodywork still needs to work, close ZJ1, ZJ2, ZJ5, ZJ6 relays to realize the chassis battery system supplying power to the bodywork load. When the vehicle chassis battery system is dead a...
