VEHICLE AND METHOD FOR CONTROLLING VEHICLE

A vehicle (1) is provided with a battery (10), a motor (20) configured to generate the driving force of the vehicle (1) by using electric power stored in the battery (10), a charger (44) configured to supply the battery (10) with electric power outputted from a power source (60) outside the vehicle (1), and an ECU (48) configured to control the charged state of the battery (10) when the battery (10) is charged. The ECU (48) calculates an index value indicating the charged state of the battery (10), and sets the control range of the index value. When a predetermined condition relating to the deterioration of the battery (10) is satisfied, the ECU (48) raises the upper limit value of the index value.
