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 deteriorating state of the battery; and
sets, based on a detected deteriorating state of the battery, an upper limit value and a lower limit value for a voltage value or an electric current value that is output from the battery to the motor or is input from the motor to the battery.

Abstract
A vehicle and method of operating a vehicle including 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.
