New energy electric vehicles energy-saving and environmental protection, safe and reliable, low cost, comfortable and flexible and many other advantages, no pollution, low noise.Compared with internal combustion engine vehicles, new energy electric vehicles do not emit pollutants when working, and the noise produced by driving motor is also less than that produced by internal combustion engine.New energy electric vehicle energy efficiency is high, its energy efficiency has exceeded gasoline engine car, especially in the city running, the car stop and go, driving speed is not high, new energy electric vehicle is more suitable.The new energy electric vehicle does not consume electricity when it stops. In the braking process, the motor can also be automatically converted into a generator to realize the recovery and utilization of energy during deceleration braking.The new energy electric vehicle has the advantages of simple structure, convenient use and maintenance. The new energy electric vehicle has the advantages of simple structure, less operation and transmission parts, and small maintenance workload. When the AC induction motor is used, the motor does not need to be maintained, and the new energy electric vehicle is easy to operate.
