<p><P>PROBLEM TO BE SOLVED: To provide a charging circuit of a series connection battery group, capable of accurately controlling a size of current flowing in a battery and charging time with respect to the battery, and capable of stably charging the battery to thereby avoid the occurrence of an excessively charged state. <P>SOLUTION: The charging circuit 1 of the series connection battery group includes a charging unit 10, one set of current control units 21, one set of switch units 22, a control unit 20 and a plurality of sets of battery connection ends 30. The current control units 21 control the current and the switch units 22 correspond to the current control units 21 one by one and they are electrically connected. The circuit is conducted and the current is circulated. The control unit 20 controls conduction or cutting of the switch unit 22, detects whether a quantity of electricity is saturated, controls the charging unit 10, supplies specified current to the battery so as to charge it or stops supply of power. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
