Pure electric vehicles use electric motors instead of fuel engines, as opposed to automatic transmissions.
The traditional internal combustion engine can limit the speed of efficient torque generation to a narrow range, which is why the traditional internal combustion engine car needs a large and complex transmission mechanism. In the pure electric vehicle driving process does not need to shift gear, easy to operate.
Compared with hybrid electric vehicles, pure electric vehicles use a single electrical energy, the electronic control system greatly reduces the internal mechanical transmission system of the car, but also reduces the energy loss and noise caused by friction of mechanical parts, saving the internal space and weight of the car.
The main difference between electric vehicles and fuel vehicles is that there are four parts: motor, speed control controller, power battery, and on-board charger, and the starting speed of electric vehicles depends on the power and performance of the drive motor.
