  • Patent number: 8798833
    Abstract: A vehicle is provided with a battery, a motor configured to generate the driving force of the vehicle by using electric power stored in the battery, a charger configured to supply the battery with electric power outputted from a power source outside the vehicle, and an ECU configured to control the charged state of the battery when the battery is charged. The ECU calculates an index value indicating the charged state of the battery, and sets the control range of the index value. When a predetermined condition relating to the deterioration of the battery is satisfied, the ECU raises the upper limit value of the index value.
    Type: Grant

  • Patent number: 8712619
    Abstract: A vehicle is equipped with a battery configured so as to be rechargeable, a motor generator configured so as to generate the driving force of the vehicle by use of electric power stored in the battery, a switch configured so as to switch between generation of a command for extending the use period of the battery and stop of generation of the command, and an ECU for controlling the state of charge of the battery. The ECU sets the control range of SOC of the battery. When the switch stops generation of the command, the ECU sets the control range to a first range. Meanwhile, when a command is generated by the switch, the ECU sets the control range to a second range narrower than the first range.
