  • Electric vehicle control device and electric vehicle
    Patent number: 11563330
    Abstract: This electric vehicle control device is provided with: an efficiency control unit which, during travel of the electric vehicle, in a state in which the battery is prone to deteriorate, increases the rate of consumption of the power charged in the battery by performing control for reducing the efficiency of the motor; a travelable distance calculation unit which calculates the travelable distance of the electric vehicle using the SOC of the battery and a travel coefficient; and a travel coefficient correction unit which, before and after the efficiency control unit performs control for reducing the efficiency of the motor, corrects the travel coefficient such that change in the travelable distance calculated by the travelable distance calculation unit is reduced.
    Type: Grant
    Filed: May 25, 2018
    Date of Patent: January 24, 2023
    Assignee: ISUZU MOTORS LIMITED
    Inventors: Yuuki Tenma, Kiyoshi Takeuchi, Shigeki Iijima
  • Electric vehicle control device that controls electric vehicle equipped with chargeable and dischargeable battery and electric motor that drives driving wheel by being supplied with electric power charged in battery, and electric vehicle
    Patent number: 11260754
    Abstract: This control device for an electric vehicle is provided with: a discharge control unit which, when the electric vehicle has been turned off, if the SOC of the battery is within a prescribed range in which the battery is prone to deteriorate, performs control for discharging the battery until the SOC has left the prescribed range; a travelable distance calculation unit which calculates the travelable distance of the electric vehicle using the SOC and a travel coefficient; and a travel coefficient correction unit which, before and after performing control for discharging the battery is performed by the discharge control unit, corrects the travel coefficient such that the travelable distance calculated by the travelable distance calculation unit is reduced.
