To provide a control module that can reduce the number of problems in which a backup battery does not secure the required remaining capacity to continue driving the load of a driving support device, etc. when the power supply from a main battery is cut off and a user wants to continue driving the load of the driving support device, etc.SOLUTION: A control module 16 includes an open circuit voltage measurement unit 32, a charge rate derivation unit 33, an internal resistance measurement unit 35, a degradation degree derivation unit 36, a target charge rate derivation unit 38 that obtains the target charge rate on the basis of the derivation result by the degradation degree derivation unit 36 such that the required remaining capacity required for the load in the backup battery 13 is secured when the power supply from the main battery 12 to the load 11 is cut off in a case in which an ignition switch 15 is on, and a charge control unit 39 that charges the backup battery 13 until the target charge rate obtained by the target charge rate derivation unit 38 is reached when it is determined that the charged rate is smaller than the target charge rate.SELECTED DRAWING: Figure 1

    【課題】メインバッテリによる電力供給が絶たれて運転支援装置等の負荷の駆動を継続させたいときに、バックアップバッテリが運転支援装置等の負荷の駆動を継続させる必要残容量を確保していないという事態の発生を低減できる制御モジュールを提供する。【解決手段】制御モジュール16は、開回路電圧計測部32と、既充電率導出部33と、内部抵抗計測部35と、劣化度合導出部36と、イグニッションスイッチ15がオンのときに、メインバッテリ12から負荷11への電力供給が絶たれた場合にバックアップバッテリ13において負荷に必要となる必要残容量が確保されるように、劣化度合導出部36による導出結果に基づいて、目標充電率を求める目標充電率導出部38と、既充電率が目標充電率よりも小さいと判断すると、目標充電率導出部38により求められた目標充電率に達するまで、バックアップバッテリ13を充電する充電制御部39と、を備える。【選択図】図1
