PROBLEM TO BE SOLVED: To provide a power control device capable of ensuring the amount of stored electricity of an on-vehicle storage battery for traveling while using both a stationary type storage battery and the on-vehicle storage battery in order to adjust the usage amount of grid electric power in a building.SOLUTION: When a power index value exceeds a discharge start threshold value DS, a charge and discharge control unit 11 of a power control device 10 preferentially starts discharge from a stationary storage battery 140, and when the power index value falls below a charge start threshold value CS, preferentially starts charging an on-vehicle storage battery 161.SELECTED DRAWING: Figure 1 【課題】建物における系統電力の使用量を調整するために、定置型蓄電池及び車載蓄電池の両方を利用しながらも、車載蓄電池の蓄電量を走行のために確保しておくことのできる電力制御装置を提供する。【解決手段】電力制御装置１０の充放電制御部１１は、電力指標値が放電開始閾値ＤＳを上回ったときには、定置蓄電池１４０からの放電を優先して開始させ、電力指標値が充電開始閾値ＣＳを下回ったときには、車載蓄電池１６１への充電を優先して開始させるように構成されている。【選択図】図１
