To secure accuracy and quality of power supply.SOLUTION: A battery controller according to an embodiment comprises a battery for auxiliaries, a connection control unit, a calculation unit, and an equalization control unit. The battery for auxiliaries is composed of a lithium ion rechargeable battery and is provided so as to be connected to/separated from an auxiliary power line of a vehicle. The connection control unit separates the battery from the auxiliary power line when the vehicle is in a predetermined state. When the battery is separated by the connection control unit, the calculation unit calculates the battery's state of charge. When the battery is separated by the connection control unit, the equalization control unit makes equalization of amounts of charge of cells of the battery be executed.SELECTED DRAWING: Figure 2B
【課題】電力供給の精度および品質を確保すること。【解決手段】実施形態に係るバッテリ制御装置は、補機用のバッテリと、接続制御部と、算出部と、均等化制御部とを備える。補機用のバッテリは、リチウムイオン二次電池からなり、車両の補機電力線に対し接続または切り離し可能に設けられる。接続制御部は、所定の車両状態時に、上記バッテリを補機電力線から切り離す。算出部は、接続制御部によって上記バッテリが切り離された場合に、当該バッテリの充電状態を算出する。均等化制御部は、接続制御部によって上記バッテリが切り離された場合に、当該バッテリのセルの充電量の均等化を実行させる。【選択図】図2B
