What are the characteristics of new energy vehicles?

The characteristics of new energy vehicles are: 1, hybrid vehicle: it has a battery, which can easily recover the kinetic energy when going downhill. In busy urban areas, the internal combustion engine can be turned off and driven only by batteries to achieve "zero" emissions; 2. Pure electric vehicle: the technology is relatively simple and mature, and it can be charged as long as there is electricity; 3. Fuel cell vehicles: zero or near zero emissions; Reduce water pollution caused by oil leakage; Reduce greenhouse gas emissions; Smooth operation, no noise; 4. Hydrogen-powered vehicles: the emissions are pure water, and no pollutants are generated when driving; 5. Supercapacitor car: short charging time, high power density, large capacity, long service life, maintenance-free, economic and environmental protection.
