Adjusting device, battery pack device, and adjusting method
First Claim
1. An adjusting device that adjusts voltage differences between a first storage battery and a second storage battery that are connected in series, comprising:
- a charging unit that charges the first and second storage batteries;
a first switching unit provided between the first storage battery and the charging unit;
a second switching unit provided between the second storage battery and the charging unit;
a detection unit that detects a first voltage of the first storage battery and a second voltage of the second storage battery; and
a control unit that, based on a determination that the first voltage is lower than the second voltage, turns ON the first switching unit and turns OFF the second switching unit.

Abstract
An adjusting device that adjusts voltage differences among a plurality of storage batteries that are connected in series is provided with: charging means that charges said storage batteries; each switching means that corresponds to each of said plurality of storage batteries, that connects a corresponding storage battery to said charging means in parallel when turned ON, and that releases the connection between the corresponding storage battery and said charging means when turned OFF; detection means that detects each voltage of said plurality of storage batteries; and control means that turns ON, from among a plurality of said switching means, the control-object switching means that corresponds to the charge-object storage battery, which has the lowest voltage that is detected by said detection means, from among said plurality of storage batteries, and moreover, that turns OFF switching means other than said control-object switching means.
