To protect a power supply line without increasing functions of a slave device in a master/slave type system.SOLUTION: In a power supply system which comprises: a battery; a master device to which power is supplied from the battery; and a slave device to which power is supplied from the master device via a first power supply line, and where the slave device supplies power to a load via a second power supply line, a temperature of the second power supply line is estimated by the master device and when the estimated temperature of the second power supply line is higher than a second cutoff threshold, power supply via the second power supply line is cut off.SELECTED DRAWING: Figure 4

    【課題】マスター・スレーブ方式のシステムおいて、スレーブ装置の機能を増加することなく、電力供給線を保護する。【解決手段】バッテリと、バッテリから電力を供給されるマスター装置と、マスター装置から第1の電力供給線を介して電力を供給されるスレーブ装置と、を備え、スレーブ装置が負荷に第2の電力供給線を介して電力を供給する電力供給システムにおいて、マスター装置により、第2の電力供給線の温度を推定し、推定された第2の電力供給線の温度が第2の遮断閾値より大きいときに、第2の電力供給線を介した給電を遮断する。【選択図】図4
