Abstract

A secondary battery system includes a secondary battery, a measurement part, a designation part, and a controller. The measurement part measures a volume change rate of the secondary battery. The designation part designates a threshold value. The controller controls a current flowing through the secondary battery, based on the volume change rate of the secondary battery measured by the measurement part and the threshold value.
