<P>PROBLEM TO BE SOLVED: To reduce electric capacitance to be received from a power source when quickly charging a battery. <P>SOLUTION: An AC/DC converting circuit 2 for converting an AC current supplied from an AC power source into a DC current and a rectifier circuit 3 are provided and a charging apparatus inside battery 7 is connected at a downstream side of the rectifier circuit 3. Further, a battery connecting terminal 5 is connected in parallel to the rectifier circuit 3 and the charging apparatus inside battery 7. A DC current which is outputted from the charging apparatus inside battery 7 charged beforehand while a charging target battery 6 is not charged, and a DC current outputted from the AC power source through the AC/DC converting circuit 2 and the rectifier circuit 3 are added and supplied to the charging target battery 6 connected to the battery connecting terminal 5 as a current corresponding to quick charging, thereby quickly charging the charging target battery 6. <P>COPYRIGHT: (C)2012,JPO&INPIT |
