Abstract
A secondary battery system according to one aspect of the present disclosure includes: a plurality of secondary batteries; a power source; and a control circuitry. The control circuitry is operative to intermittently charges each of the plurality of secondary batteries plural times with a pause between charges while repeating a cycle including (a) selecting a secondary battery to be charged next from among the plurality of secondary batteries and (b) charging the selected secondary battery at a charging current not less than a standard current. The standard current is defined to reduce a charging capacity of each secondary battery decreases by 20% from a maximum charging capacity in a case where the secondary battery is continuously charged at the standard current.
