The high-voltage components of new energy vehicles mainly include the following:
1. Power battery: As the power source of new energy vehicles, the voltage of the power battery can reach up to 100~400V, and the output current can reach 300A. Its capacity directly determines the vehicle's range, charging efficiency, and time.
2. Drive motor and motor controller MCU: The drive motor is responsible for converting the electrical energy in the battery into mechanical energy to drive the vehicle. The motor controller MCU is responsible for converting high-voltage direct current into alternating current and exchanging signals with other modules to achieve precise control of the driving motor.
3. High voltage distribution box PDU: The high voltage distribution box is a power distribution device for the vehicle's high voltage electricity. It mainly distributes high voltage power to various actuator drives and coordinates the functional conversion and energy distribution of high voltage accessories such as the drive motor control system, battery management system, charging management system, DC/DC converter, electric air conditioning, electric power steering, braking system, etc.
