All or part of a vehicle driven by

All or part of a vehicle driven by an electric motor and equipped with a large capacity electric energy storage device is collectively called an electric vehicle. The components of an electric vehicle include the electrical drive and control systems, the transmission of motive power and other mechanical systems, and the work equipment to accomplish established tasks. Electric drive and control systems are at the heart of electric vehicles and the biggest difference from vehicles with internal combustion engines. The electric drive and control system consists of a drive motor, power supply, and motor speed controller. The Equipment of other electric vehicles is basically the same as that of internal motor vehicles. When working on an electric vehicle, the power supply supplies electric power to the drive motor of the electric vehicle. The drive motor converts electrical energy from the power source into mechanical energy and drives the wheels and work equipment directly in the transmission or directly. The drive unit converts the driving torque of the motor into force applied to the ground through the wheels and drives the wheels to walk. electric vehicle drive.
