Abstract
A battery systemincludes an upper-limit electrical quantity setting means (an ECU) for setting an upper limit of an electrical quantity (an upper-limit electrical quantity Da) obtainable from a battery packto a lower value than in a full charge state. This upper-limit electrical quantity setting meanssets the upper-limit electrical quantity Da to a value having a difference from the electrical quantity (a full-charge electrical quantity Dmax) obtainable from the full charge state so that the difference is smaller as the deterioration of the battery packprogresses. Further, the battery systemincludes a charging means (the ECU) for charging the battery packunder the condition that the upper-limit electrical quantity Da is an upper limit.
