Abstract
A battery pack for providing different power sources may include: a low voltage battery configured to supply a first voltage; a high voltage battery configured to supply a second voltage, the second voltage being higher than the first voltage; a charging circuit configured to charge the low voltage battery using the high voltage battery; and/or a controller configured to control the charging circuit to charge the low voltage battery when a charge state of the low voltage battery is less than a desired charge state.
