A state estimation unit estimates an OCV upon charging a battery. Pulse charging units applies a charging pulse voltage to the battery when the OCV is larger than a first predetermined value. The state estimation unit estimates the OCV by sequentially calculating a coefficient of a transmission function based on an equivalent circuit model of the battery each time the pulse charging units apply the charging pulse voltage. The pulse charging units compare the OCV to a second predetermined value that is larger than the first predetermined value. The pulse charging units determine to apply the next pulse voltage in the pulse charging units when the estimated OCV is smaller than the second predetermined value, and determine to end charging the battery when the OCV is larger than the second predetermined value.
