摘要: A voltage measurement apparatus is provided in which: among battery cells which make up a battery-cell group, sampling switch electrically connects any one or more targeted for to capacitor so that the charged by these cells; section acquires of as and corrects error caused inter-terminal capacitance can be narrowed; an over-voltage prevention turns on immediately before turned grounds input terminal protected from over-voltage.
