A battery system for a vehicle warms up a battery, which is mounted to charge and discharge. A charge/discharge unit is located closer to a battery set than an inverter unit is. When the battery set cannot produce a required output power because of its low temperature, a control unit controls the charge/discharge unit to charge and discharge and also controls a blower to deliver heat transfer medium, which receives heat generated from the charge/discharge unit, to the battery set, so that the battery set is warmed up to produce the required output power at earlier time.
