Abstract
A regenerative braking control system for a motor-driven vehicle is configured to provide a continuous assistant braking force by continuous reverse torque of an electric motor by enabling surplus electrical energy produced by an electric motor to be easily converted into thermal energy in generative braking, using both of a brake resistor and a heater to convert electrical energy into thermal energy, and being able to obtain an interior heating effect by using thermal energy converted by the brake resistor and the heater as heat source for interior heating without discharging the thermal energy to the outside.
Claims17
A regenerative braking control system for a motor-driven vehicle, the regenerative braking control system comprising:
- an electric motor configured to charge a battery with an electrical energy by operating as a power generator in regenerative braking;
- a brake resistor configured to convert surplus electrical energy produced by the electric motor into thermal energy in regenerative braking;
- a heater configured to convert surplus electrical energy produced by the electric motor into thermal energy together with the brake resistor;
- a cooling water circulation line connected to the brake resistor and the heater so that cooling water can circulate;
- and
- a controller configured to control the brake resistor and the heater to be turned on and off on the basis of charged amount information of the battery so that a heating mode, a regenerative braking mode, a heating and regenerative braking mode, and a maximum regenerative braking mode are performed.
