The electric motor converts electrical energy into mechanical energy to drive the car. Different from the traditional fuel vehicle’s engine, which converts the chemical energy of fuel combustion into mechanical energy, its working efficiency is higher, which can reach more than 85%. Therefore, compared with traditional vehicles, its energy utilization rate is higher, which can reduce the waste of resources.
High Voltage Distribution Box (PDU)
The high-voltage distribution box is a power distribution device for the high-voltage power of the vehicle, similar to the electrical fuse box in the low-voltage circuit system. The high-voltage fuse box PDU (Power Distribution Unit) is composed of many high-voltage relays and high-voltage fuses. It also has related chips inside it to realize signal communication with related modules and ensure the safety of high-voltage power consumption of the whole vehicle.
