The components of the high-voltage system for new energy vehicles mainly include:
1. Power battery: responsible for storing and discharging electrical energy, providing the power source for new energy vehicles.
2. Drive motor and motor controller: The drive motor is responsible for converting the electrical energy in the battery into mechanical energy to drive the vehicle; The motor controller is responsible for regulating the energy transfer between the battery pack and the driving motor.
3. High voltage distribution box, electric compressor, DC/DC converter, onboard charger, power output controller, and high-voltage wiring harness:
High voltage distribution box: manages battery power output and is the distribution device for the vehicle's high-voltage power supply.
Electric compressor: specifically designed for air conditioning systems, producing cold air by compressing refrigerant.
DC/DC converter: a device that converts high voltage direct current into low voltage direct current to maintain the balance of the vehicle's electricity consumption.
Car charger: converts AC power to DC power to charge the power battery.
Power output controller: When needed, it recovers the vehicle's kinetic energy and converts it into electrical energy to enhance the battery's endurance.
High voltage wiring harness: Like the nervous system, it tightly connects all components to ensure the stable operation of the high-voltage system.
