pure electric vehicles, it means a fully charged battery to power an electric motor, an electric motor driven by the vehicle, and the battery power from an external power source complement, and in line with road traffic vehicles, the requirements of safety regulations.
1. What is the electric vehicle
car completely pure electric vehicles powered by a rechargeable battery source, due to the small impact on the environment compared to conventional cars, which are widely promising prospects. Composition
The electric vehicle comprising: an electric drive and control system, the driving force transmission and other mechanical systems, equipment and the like to perform a given task.
Electric drive and control system is the core of an electric vehicle, the maximum is different from an automobile engine is different.
electric drive and control system by the drive motor speed, the motor power supply and control devices and other components.
Other means of an electric vehicle and substantially the same internal combustion engine vehicle.
2. What are the advantages and disadvantages of pure electric vehicles
advantages of 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.
shortcomings 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 cars, some results only 1/3 of the car, depending on the battery life and the local oil and electricity prices.
