Battery voltage measurement device |
摘要 |
A battery voltage measurement device includes: a plurality of first switching sections, wherein each pair of adjacent first switching sections sequentially selects two output terminals of each of a plurality of battery blocks included in a battery pack; a level change section for changing a level of a battery voltage of each battery block which is input to the level change section via the first switching section; an A/D conversion section for performing an A/D conversion of battery voltage data output from the level change section; and a reference voltage control section for controlling an output of a reference voltage of the level change section according to the polarity of the voltage input to the level change section. <IMAGE> |
