Abstract
A voltage detection apparatus includes a supervisory unit that detects terminal voltage of battery cells that constitute a battery module, a high potential path, a low potential path, a differential amplifier that detects terminal voltage of the battery module. First and third switches are provided on the high potential path and second and fourth switches are provided on the low potential line. The voltage detection apparatus includes a bypass resistor that electrically connects the high potential path and the low potential path.
