<p>PURPOSE:To detect and control the charge/discharge current of a plurality of batteries with only one battery current detecting circuit. CONSTITUTION:This has only one current detecting circuit 4 and a power source microcomputer 5, which has a port for permitting or inhibiting the charge/ discharge of each battery 1 and 2, and the power source microcomputer 5 detects the direction of the current which flows to the current detecting circuit 4, and judges the charge/discharge status that each battery 1 and 2 has, and when it is in charge condition (or in discharge condition), it decides which battery of a plurality of batteries should discharge (or should be charged) and instructs it.</p> |
