Internal combustion engine vehicles emit a lot of air pollutants every day, which brings serious harm to human health and the ecological environment. Therefore, energy conservation and emission reduction are the eternal theme of the development of the automobile industry. Electric vehicle charging pile

What are the characteristics of electric vehicles?

A pure electric vehicle is a vehicle driven by an on-board power supply and driven by an electric motor. The difference between electric vehicle and internal combustion engine vehicle mainly lies in its power supply, motor and speed control device of motor.

Electric vehicles have the following characteristics:

No pollution, low noise

The exhaust gas produced by electric vehicles without internal combustion engines when they work does not produce exhaust pollution, which is very beneficial to environmental protection and air cleanness, almost "zero pollution". The electric vehicle has no noise generated by the internal combustion engine, and the noise of the motor is smaller than that of the internal combustion engine.

Simple structure and convenient maintenance

Electric vehicles do not need the engine and its auxiliary muffler, exhaust pipe, fuel tank and other devices required by internal combustion engine vehicles. Because the motor can change the steering direction and control the speed, the electric vehicle no longer needs a clutch and a transmission. Compared with internal combustion engine vehicles, electric vehicles have simpler structure, fewer transmission parts and less maintenance work. When AC induction motor is used, the motor does not need maintenance.

Short range, suitable for short trips

The difficulty in the development of electric vehicles mainly lies in the power storage technology, that is, power battery technology. At present, the energy stored in the power battery can only provide about 300km of vehicle endurance. Only a few advanced models can reach more than 500km, and the charging time is relatively long, usually 10 minutes to several hours.
