Abstract
A battery charging apparatus includes a converting unit, first and second charging units and a switching unit. The converting unit separately convert AC power into a first voltage and a second voltage. The first charging unit drops the converted first voltage and charge a high voltage battery with the dropped first voltage. The second charging unit drops the converted second voltage or a third voltage of the high voltage battery, and charges an auxiliary battery with the dropped second or third voltage. The switching unit performs, in a first mode, the charging of the high voltage battery and the auxiliary battery by the AC power, and in a second mode, stops the charging of the high voltage battery by the AC power and performs the charging of the auxiliary battery by the third voltage.
