PROBLEM TO BE SOLVED: To protect a battery by changing control processing of a relay that is provided between the battery and a load, in accordance with an abnormality that occurs in the battery.SOLUTION: A relay control device 1 comprises: a plurality of module relays 3 which are provided between one or more batteries 2 connected in parallel and a load 5; and a control part 13 by which, if a first abnormality occurs in at least one battery 2 among all the batteries 2, all the module relays 3 are turned off so as to electrically disconnect all the batteries 2 and the load 5 after awaiting the lapse of a predetermined time T and if a second abnormality with higher importance than that of the first abnormality occurs in at least one battery among all the batteries 2, all the module relays 3 are turned off so as to electrically disconnect all the batteries 2 and the load 5 without awaiting the lapse of the predetermined time T.SELECTED DRAWING: Figure 1

    【課題】電池に発生する異常に応じて、電池と負荷との間に設けられるリレーの制御処理を変えることで、電池を保護する。【解決手段】一つ又は複数並列接続される電池2と負荷5との間に設けられる複数のモジュールリレー3と、全電池2のうちの少なくとも一つの電池2に第1の異常が発生すると、所定時間Tを待ってから、全電池2と負荷5とが電気的に遮断されるように全モジュールリレー3をオフさせ、全電池2のうちの少なくとも一つの電池2に第1の異常よりも重要度が高い第2の異常が発生すると、所定時間Tを待たずに、全電池2と負荷5とが電気的に遮断されるように全モジュールリレー3をオフさせる制御部13とを備えてリレー制御装置1を構成する。【選択図】図1
