ABSTRACT:
The invention provides a brake control apparatus for an electric motor vehicle that can control a charging current depending on a charging state of a dc power supply to avoid overcharging it. In regenerative braking, according to the invention, the charging state of a battery is detected by a charging state detector, which sends a detection signal to a control unit. When the state of charge of the battery exceeds a predetermined level, the control unit controls operating parameters of an inverter so that the charging current to the battery is decreased. If, however, insufficient torque results, the control unit turns on an electric load to increase the control torque. If further load absorption is needed, the control unit turns on electric braking means.
