Zusammenfassung: | To supply power to a load connected to a power source port of high priority even if a remaining capacity of a battery is low.SOLUTION: In a power source device 10, a frequency detection unit 30 detects, for each of a plurality of power source ports 11 to 14 for supplying power of a battery 20 to connected loads 201 to 204, a frequency of supplying the power to the loads 201 to 204 connected with the power source ports 11 to 14. On the basis of the frequency detected by the frequency detection unit 30, a priority determination unit 40 determines priority levels of the power source ports 11 to 14 for each of the power source ports 11 to 14. A remaining-capacity detection unit 60 detects a remaining capacity of the battery 20. If the remaining capacity detected by the remaining-capacity detection unit 60 decreases to a prescribed capacity, a control unit 80 stops supply of the power of the battery 20 to one or more of the power source ports 11 to 14 the priority levels of which are lower than that of the power source port having the highest priority level of the power source ports 11 to 14.SELECTED DRAWING: Figure 2
【課題】バッテリの残容量が少なくなっても、優先度の高い電源ポートに接続した負荷に対して電力を供給する。【解決手段】電源装置10では、頻度検出部30が、接続された負荷201~204に対してバッテリ20の電力を供給する複数の電源ポート11~14毎に、電源ポート11~14に接続された負荷201~204に電力を供給した頻度を検出する。優先度決定部40は、頻度検出部30が検出した頻度に基づいて、電源ポート11~14の優先度を電源ポート11~14毎に決定する。残容量検出部60は、バッテリ20の残容量を検出する。制御部80は、残容量検出部60が検出した残容量が所定容量まで減少した場合に、優先度が最も高い電源ポート11~14よりも低い1又は2以上の電源ポート11~14に対するバッテリ20の電力供給を停止させる。【選択図】図2 |
