PURPOSE:To detect abnormality of individual battery quickly and reliably by connecting individual batteries through individual battery switches and block diodes with a DC power supply while connecting a charge means through individual block-diodes and a current detecting means with individual batteries. CONSTITUTION:A battery group is constituted of first, second and third batteries 6A, 6B, 6C, first, second and third switches 7A, 7B, 7C and first, second and third diodes 8A, 8B, 8C connected in parallel. Furthermore, a circuit is provided for charging the first, second and third batteries 6A, 6B, 6C, respectively, through fourth, fifth and sixth diodes 21A, 21B and 21C and first, second and third current transformers 22A, 22B and 22C. Consequently, three sets of batteries can be charged individually and the charge current or the battery terminal voltage can be measured individually. |
