What are the advantages of pure electric vehicles?

Pure electric vehicle refers to a vehicle powered by on-board power supply and driven by motor, which meets the requirements of road traffic and safety regulations. Because it has less impact on the environment than traditional cars, its prospect is widely optimistic, but the current technology is not mature.

Advantages of pure electric vehicles:

No pollution, low noise

The exhaust gas produced by electric vehicles without internal combustion engines does not produce tail gas pollution, which is very beneficial to environmental protection and air purification, and is almost "zero pollution". As we all know, CO, HC, NOX, particulate matter, odor and other pollutants in the exhaust gas of internal combustion engine vehicles form acid rain, acid fog and photochemical smog. Electric cars have no noise generated by internal combustion engines, and the noise of motors is also smaller than that of internal combustion engines. Noise is also harmful to people's hearing, nerves, cardiovascular system, digestion, endocrine and immune system.

A single power source

Compared with hybrid electric vehicles and fuel cell vehicles, pure electric vehicles use electric motors instead of fuel engines, with low noise and no pollution. The space and weight occupied by electric motors, fuel and transmission systems can be used to make up for the needs of batteries. And because of the use of a single electric energy source, the electronic control system is greatly simplified compared with the hybrid electric vehicle, which reduces the cost and can also compensate part of the price of the battery.

Simple structure and convenient maintenance.

Compared with internal combustion engine vehicles, electric vehicles have simpler structure, fewer running and transmission parts and less maintenance workload. When using AC induction motor, the motor does not need maintenance, and more importantly, the electric vehicle is easy to operate.

High energy conversion efficiency

At the same time, it can recover the energy during braking and downhill, and improve the utilization efficiency of energy.

Stabilize the peak-valley difference of power grid

At night, you can use the cheap "valley power" of the power grid to charge, which can stabilize the peak-valley difference of the power grid.
