What parts does the high-voltage system of new energy vehicles generally consist of?

Power battery, drive motor, high-voltage distribution box (PDU), electric compressor, DC/DC, OBC, PTC, high-voltage wiring harness, etc. These components constitute the high-voltage system of the whole vehicle, among which the power battery, the drive motor and the high-voltage control system are the three core components of the pure electric vehicle.

The power source of new energy electric vehicles is the power battery, not the engine. Because pure electric vehicles use electric energy directly, they don't need to burn fuel like traditional fuel vehicles and discharge emissions into the atmosphere.

Extended data

It provides electric energy for the driving motor of the electric vehicle, and the motor converts the electric energy of the power supply into mechanical energy. At present, the most widely used power supply is lead-acid battery, but with the development of electric vehicle technology, lead-acid battery is gradually replaced by other batteries because of its low energy, slow charging speed and short life.

The main power sources being developed are sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries and fuel cells. The application of these new energy sources has opened up broad prospects for the development of electric vehicles.
