The energy output from the energy storage system
Jun 12, 2018

The electric vehicle power drive system is the link between the energy storage system and the wheels. Its role is to convert the energy (chemical energy, electrical energy) output by the energy storage system into mechanical energy, and to push the vehicle to overcome various rolling resistance, air resistance, acceleration resistance and The climbing resistance, when braking, converts the kinetic energy into electrical energy and feeds back to the energy storage system. Unlike conventional fuel vehicles, Hyundai Electric Vehicles can eliminate complicated and bulky mechanical gear shifting mechanisms and provide torque speed characteristics that satisfy a wide range of vehicle travel speeds and large load changes.

Electric cars can be single-motor or dual-motor drive, and shaft motors or wheel motors can also be used. Currently, small-power electric vehicles such as electric cars that are sold on the market use simple single-motor power drive systems, while mid- and high-power electric vehicles such as electric buses generally use single-motor or double-motor power drive systems.
