摘要： An electric vehicle control apparatus includes a first motor generator, a second motor generator, a booster, and a controller. The booster boosts an input voltage to the first motor generator and an output voltage from the second motor generator to expand an operable range of the first motor generator and an operable range of the second motor generator into a first expanded operable range and a second expanded operable range, respectively. The controller controls the first motor generator to drive a load with regenerative power supplied during braking of an electric vehicle and to control the first motor generator to be driven at a first inefficient operating point within the first expanded operable range and to control the second motor generator to be driven at a second inefficient operating point within the second expanded operable range in a case where the regenerative power is used.

摘要： A vehicle includes an electric motor to move the vehicle. A motor driver is configured to convert direct-current power supplied from a voltage converter to an alternating-current power and to convert the alternating-current power supplied from the electric motor to direct-current power. Circuitry is configured to drive the electric motor with a first current value to generate a drive force to consume excess electric power. The first current value is different from a minimum current value to generate the same drive force. The circuitry is configured to drive the electric motor with a second current value smaller than the first current value to decrease the electric power consumption of the electric motor when a temperature of the electric motor exceeds a first threshold temperature or a temperature of the motor driver exceeds a second threshold temperature.

摘要： A vehicle includes an energy storage, a motor driver, an electric motor, and circuitry. The motor driver is configured to convert direct-current power to alternating-current power and to convert alternating-current power to direct-current power. The electric motor is connected to the energy storage via the motor driver to move the vehicle. The circuitry is configured to drive the electric motor with a first current value to consume excess electric power. The first current value is different from a minimum current value to generate regeneration power arising from a braking force. The circuitry is configured to drive the electric motor with a second current value smaller than the first current value if a temperature of the electric motor is higher than a first threshold temperature or a temperature of the motor driver is higher than a second threshold temperature.
