Its performance is relatively stable, the speed is slow, the use of electricity without refueling, it is also known as environmentally friendly elderly car, elderly electric vehicles use a lot of energy, mainly lead-acid battery (containing lead-acid colloidal battery), nickel hydride battery, nickel-cadmium battery, nickel-iron battery, lithium ion battery (often referred to as lithium battery), fuel cells. Fuel cells convert chemical energy directly into electrical energy in an electrochemical manner, isothermal. It does not go through the heat engine process, so it is not restricted by the carnot cycle, and the energy conversion efficiency is high (40-60%). Virtually no emissions of NOx and SOx are produced. Moreover, CO2 emissions are more than 40 percent lower than those from conventional power plants.
