PROBLEM TO BE SOLVED: To provide a power supply controller, a battery pack, and a power supply system, in which even when power supply from first power supply is stopped, a second electric load is inhibited from coming into an off state.SOLUTION: A power supply system comprises: first power supply; a power generator; a first electric load electrically connected to the first power supply and the power generator; a second electric load that is electrically connected to the power generator and comes into an off state when supply electric energy is lower than a reset threshold; a second power supply electrically connected to the second electric load and the power generator; and a charge/discharge switch provided between the second power supply and the power generator. When an amount of charge of the second power supply is lower than a charge request threshold, the power generator is in a power generation state for generating power, and power generation electric energy generated by power generation of the power generator is equal to or larger than total request electric energy, the total sum of request electric energy of the second power supply, the first electric load, and the second electric load, the power supply system causes the charge/discharge switch to come into a closed state to electrically connect the power generator and the second power supply.SELECTED DRAWING: Figure 6

    【課題】第1電源の電力供給が途絶えたとしても、第2電気負荷がオフ状態になることの抑制された電源制御装置、電池パック、および、電源システムを提供する。【解決手段】第1電源と、発電機と、第1電源および発電機と電気的に接続された第1電気負荷と、発電機と電気的に接続され、供給電力量がリセット閾値を下回るとオフ状態になる第2電気負荷と、第2電気負荷および発電機と電気的に接続された第2電源と、第2電源と発電機との間に設けられた充放電スイッチと、を備えた電源システムにおいて、第2電源の充電量が充電要求閾値を下回り、発電機が電力を生成する発電状態であり、なおかつ、発電機の発電によって生成される発電電力量が第2電源、第1電気負荷、および、第2電気負荷それぞれの要求電力量の総和である総要求電力量以上の場合、充放電スイッチを閉状態にして発電機と第2電源とを電気的に接続する。【選択図】図6
