EV electric vehicle classification according to the number and structure of the tire types can be divided into: electric bicycles; electric motorcycle; electric wheelbarrow closed electric tricycle, four electric vehicles; electric tricycles; electric scooters; according to the source of power: pure electric vehicles , increasing program electric vehicles, hybrid electric vehicles offer fully enclosed electric tricycle, fuel cell vehicles. By way of providing electricity can be divided into two categories, one is connected to an external power source to obtain power, the other is to use fuel cells, energy storage devices (such as storage battery electric tricycle closed much money, super capacitors), etc., as electricity. An electric vehicle performance, lead-acid batteries (including lead-acid gel batteries), the cost is cheap, stable performance, the electric car on the market use of such batteries. 2, the lithium-ion battery (often referred to as lithium batteries), expensive, unstable performance, prone to explode, low safety factor. Being developed using lithium iron phosphate battery solve the security problem. Being further improved. 3, crystal plastic battery, high cost, stable performance, the use of such batteries of electric vehicles on the market are rare, only a few merchants had to configure this high-performance battery, the highest safety factor. Life is much higher than the first two types of batteries superiority advantage and self-healing capabilities is the industry's leading position, the advantage is the lead-acid batteries do not have to avoid the disadvantages of lead-acid batteries stratification.
