Abstract: A vehicle includes a controller. When a brake operation amount has increased, the controller calculates an estimated input value at the time when a main battery is charged in response to an increase in the brake operation amount, on the basis of a current speed and an amount of increase in brake operation amount. The controller discharges the main battery for charging an auxiliary battery at a current value that is calculated on the basis of the estimated input value by controlling an operation of a DC-DC converter before charging the main battery in response to an increase in the brake operation amount. Thus, it is possible to cancel a bias of salt concentration that is developed during charging by a bias of salt concentration that is developed during discharging, so, after the main battery has been charged, it is possible to suppress development of a bias of the salt concentration and suppress an increase in the internal resistance value of the main battery.
