Battery unit voltage detection device

Abstract

A battery unit voltage detection device includes: a battery unit including a plurality of battery cells; a voltage detection means being electrically connected to the battery unit and detecting a voltage value of the battery unit; a first capacitor being electrically connected to a positive electrode end of the battery unit and a negative electrode end of the battery unit; a second capacitor being electrically connected to the positive electrode end of the battery unit and the negative electrode end of the battery unit, and disposed closer to the voltage detection means than the first capacitor; a voltage divider resistor disposed between the battery unit and the first capacitor, and dividing a voltage of the battery unit; a battery side switch disposed between the battery unit and the first capacitor; and a detection side switch disposed between the first capacitor and the second capacitor.
