The electric drive system of Electric Car includes electronic controllers, power converters, motors, mechanical transmission devices and wheels. Its function is to efficiently convert the electrical energy stored in the battery into the kinetic energy of the wheels, and to convert the kinetic energy of the wheels into electrical energy to charge the battery when the car decelerates and brakes.
The latter function is called regenerative braking. The power system includes power supply, energy management system and charger. Its function is mainly to provide driving power to the electric motor of the Electric SUV Car, monitor the power usage and control the charger to charge the battery.
The auxiliary system of Electric Car includes auxiliary power source, power steering system, navigation system, air conditioner, lighting and defrosting device, wiper and radio, etc. These auxiliary equipment are used to improve the maneuverability of Electric Car and the comfort of passengers.
