Abstract
A battery controller 6 is connected to a DC/DC converter 3. The battery controller 6 checks the capacities of a battery 4 and a battery 5, calculates a duty ratio between the battery 4 and the battery 5 based on the capacities to determine a switching timing in which a plurality of switching elements are to be switched, and sets the duty ratio in the DC/DC converter 3.
