What is?
pure electric vehicles, it means a fully charged battery power supply to the motor vehicle driven by an electric motor, and the battery power is supplemented by an external power supply, and meet the requirements of road traffic and safety regulations Vehicles.

You know what?
is fully electric vehicle car provided by a rechargeable battery power source, due to the small impact on the environment compared to conventional cars, which are widely promising prospects.
composed of an electric vehicle comprising: an electric drive and control system, the driving force transmission and other mechanical systems, to complete a given task work devices. Electric drive and control system is the core of electric vehicles, the biggest difference is different from the internal combustion engine vehicles. Electric drive and control system by a speed control unit for driving the motor, and a motor power supply components. Other means of substantially identical electric vehicle internal combustion engine vehicle.

What are the advantages and disadvantages?
advantages
mature technology is relatively simple, as long as the local power supply can be charged. As the torque output of the motor stability control is also easier than internal combustion engines, electric vehicles traveling relatively smooth, vibration and noise is also small.
drawbacks
battery stored energy per unit weight is too small, but also because of battery electric vehicles more expensive, not any form economies of scale, so the purchase price is more expensive, as the cost, some trial results more expensive than the car, the car is only the result of some 1/3, depending on the battery life and the local oil and electricity prices.
