<p>PROBLEM TO BE SOLVED: To provide a battery system for a vehicle capable of suppressing progress of degradation of a second storage battery.SOLUTION: When charging a first storage battery 11 and a second storage battery 12, during a normal period, inner opening/closing means 24 is connected and the first storage battery 11 and the second storage battery 12 are charged at the same time. However, in a case where a charge rate of the second storage battery is detected to be a lower limit threshold value or less and it is determined that there is no power generation margin, the inner opening/closing means 24 is controlled to be an open state.</p> |
