Product description

The electric drive system includes a motor, a motor controller and a transmission mechanism. Some electric cars can drive their wheels directly from an electric motor Electric vehicle electric drive mode can be basically divided into motor central drive and electric wheel drive two. Pure electric vehicle (EV), as its name implies, is a vehicle that simply relies on on-board power supply to provide driving force in line with vehicle power requirements. Pure electric vehicles have no engine, and the supplement of electric energy depends on external power supply. It can be seen that the electric motor of a pure electric vehicle is equivalent to the engine of a traditional car, and the battery is equivalent to the original fuel tank. The composition of pure electric vehicle is composed of three major parts: electric drive main module, on-board power module and auxiliary module. Electric drive and control system is the core of electric vehicles, which is also the biggest difference from internal combustion engine cars. Motor drive system is the heart of electric vehicles, which is composed of motor, power converter, controller, various detection sensors and power supply (battery).
