What are the basic principles of pure electric vehicles?

[MacChase]

Pure electric vehicles replace the internal combustion engine with an electric motor, which drives the vehicle without the need for an automatic transmission. Compared to automatic transmissions, electric motors have a simpler structure, mature technology, and reliable operation. Advantages of pure electric vehicles: 1. No pollution and low noise: Electric vehicles do not produce exhaust gases like internal combustion engine vehicles, resulting in no exhaust pollution, which is highly beneficial for environmental protection and air cleanliness, almost achieving 'zero pollution'. 2. Single energy source: Compared to hybrid and fuel cell vehicles, pure electric vehicles replace the internal combustion engine with an electric motor, offering low noise and no pollution. The space and weight saved by eliminating the motor, fuel, and transmission systems can be used to compensate for battery requirements. 3. Simple structure and easy maintenance: Electric vehicles have a simpler structure than internal combustion engine vehicles, with fewer moving and transmission parts, resulting in less maintenance work. 4. High energy conversion efficiency: They can also recover energy during braking and downhill driving, improving energy utilization efficiency.
