New energy vehicles refers to the use of unconventional car as the power source for fuel (or the use of conventionalvehicle fuel, using a new type of vehicle power unit), advanced technology and power control and drive the overallvehicle, the technical principle, the formation of the new structure and new technology has advanced, car.

New energy automobile gas vehicle (including liquefied natural gas, compressed natural gas), fuel cell electric vehicle(FCEV), a pure electric vehicle (BEV), liquefied petroleum gas vehicles, hydrogen energy power cars, hybrid electric vehicle (oil and gas hybrid, hybrid) solar cars and other new energy sources (such as efficient energy storage device)car, the low emissions.

Pure electric vehicle

     Advantages: the technology is relatively simple and mature, as long as there are places where the power supply iscapable of charging.

     Disadvantages: the battery unit weight of stored energy is too little, but also because of the battery electric cars more expensive, and no economy of scale formation, the purchase price is more expensive, but the use of cost, some trialresults than the car is expensive, some results for the car only 1/3, it mainly depends on the battery life and the localoil, electric price.

      From the development of the global new energy vehicle, the power supply includes a lithium ion battery, Ni MH battery, fuel battery, lead-acid battery, super capacitor, which the lead-acid battery, super capacitor is mostly based on the auxiliary power source form. The main reason is that battery technology is not fully mature or shortcomingsobviously, compared with the traditional automobile whether from the cost, power or mileage has many gaps, this is also an important reason that restricts the development of new energy vehicles.

      Other uses of drive system including: gasoline and fuel injection pump, air conditioning, adjustable shock absorber,power steering, speed meter, throttle adjuster, ranging system and fuel cell vehicles.
