Voltage monitoring device

Abstract

PROBLEM TO BE SOLVED: To provide a flying capacitor type voltage monitoring device capable of reducing the number of parts.SOLUTION: The voltage monitoring device includes: first input side switches SWi for connecting, to electrode terminals spaced only by the number of a connection edge A3 between adjacent capacitors C1 and C2 among electrode terminals T1 to T15 of respective battery cells V1 to V14 constituting a battery pack 1, a pair of independent edges A1 and A2 in the capacitors; and second input side switches SWj for connecting, to the electrode terminals other than the electrode terminals to which the first input side switches SWi are connected among the electrode terminals T1 to T15 of the respective battery cells V1 to V14, the connection edge A3 between the capacitors C1 and C2. The number of the second input side switches SWj is smaller than the number of the electrode terminals other than the electrode terminals to which the first input side switches SWi are connected among the electrode terminals T1 to T15 of the respective battery cells V1 to V14.
【課題】部品点数の低減を図ることができるフライングキャパシタ方式の電圧監視装置を提供する。 【解決手段】組電池1を構成する各電池セルV1〜V14の電極端子T1〜T15のうち、隣接するキャパシタC1、C2間の接続端A3の数だけ間隔のあいた電極端子に、キャパシタにおける一対の独立端A1、A2を接続する第1入力側スイッチSWiと、各電池セルV1〜V14の電極端子T1〜T15のうち、前記第1入力側スイッチSWiが接続された電極端子以外の電極端子に、キャパシタC1、C2間の接続端A3を接続する第2入力側スイッチSWjと、を備え、第2入力側スイッチSWjの数が、各電池セルV1〜V14の電極端子T1〜T15のうち、第1入力側スイッチSWiが接続された電極端子以外の電極端子の数よりも少なくなっている。 【選択図】図1
