Traction Motor System

SYSTEM

MOTOR REGENERATION CONTROL : System Description

During deceleration, the traction motor inverter drives the traction motor to function as a generator based on the regenerative torque command signal sent via EV system CAN from the VCM, converting the kinetic torque generated by rotation of the tires into electrical energy. The converted electrical energy charges the Li-ion battery.
The regenerative torque that is generated when the traction motor is driven as a generator can be used as braking force, acting similar to engine braking and reducing the burden on the service brakes.
