To provide a power supply system and a method for controlling the power supply system that prevent the discharge of an additional battery due to a dark current in a load.SOLUTION: A power supply system, which is installed in a vehicle having a normal driving mode by a driver and an autonomous driving mode, comprises a first load circuit, a second load circuit, a first relay, a second relay, and a controller. The first load circuit is connected to a first load, which operates with electric power from a main battery and is required for continuation of the normal driving mode. The second load circuit is connected to a second load, which operates with electric power from the main battery or an additional battery and is required for continuation of the autonomous driving mode. The first relay is provided to a feeder connecting the first and second loads to allow or disallow conduction between the first and second load circuits. The second relay allows or disallows conduction between the additional battery and the second load. The controller determines whether the driving mode of the vehicle is the normal driving mode or the autonomous driving mode.SELECTED DRAWING: Figure 1

    【課題】負荷の暗電流による追加バッテリの放電を防止する電源システム及び電源システムの制御方法を提供する。【解決手段】運転者による通常運転モードと、自動運転モードを有する車両に搭載された電源システムは、第1負荷回路と、第2負荷回路と、第1リレーと、第2リレーと、コントローラとを備える。第1負荷回路は、主バッテリからの電力により動作し、通常運転モードの継続に必要な第1負荷が接続されている。第2負荷回路は、主バッテリ又は追加バッテリからの電力により動作し、自動運転モードの継続に必要な第2負荷が接続されている。第1リレーは、第1負荷と第2負荷を接続する給電線に設けられ、第1負荷回路と第2負荷回路の間を導通又は遮断する。第2リレーは、追加バッテリと第2負荷の間を導通又は遮断する。コントローラは、車両の運転モードが通常運転モード又は自動運転モードであるかを判定する。【選択図】図1
