First Claim
Patent Images
1. A vehicle, comprising:
- a motor that supplies a driving force to a wheel;
a battery that supplies electric power to the motor and receives regenerative electric power from the motor; and
a controller that;
detects a state of the battery; and
sets, based on a detected state of the battery, a first upper limit value and a first lower limit value for a voltage value and an electric current value that is output from the battery to the motor, and a second upper limit value and second lower limit value for the voltage value and the electric current value that is input from the regenerative electric power to the battery.
