Electric car is a vehicle that uses electrical energy as a power source to drive the car. Its energy mainly comes from the on-board battery pack, and the motor replaces the engine to drive the car. Types of electric car include pure electric car, plug-in hybrid electric vehicles (PHEV), and fuel cell car.

The advantages of electric car mainly include zero emissions, low noise, high efficiency, etc. Since electric car use electric energy as a power source, they do not produce exhaust gas and noise pollution during driving, and have better environmental performance than traditional internal combustion engine vehicles. In addition, the energy utilization rate of electric car is also higher than that of traditional fuel cars, and they can achieve higher energy conversion efficiency.
