To provide a power supply controller for appropriately securing an amount of charge of an output type power supply in preparation for the next running time.SOLUTION: A power supply controller 80 is applied to a power supply system 10 comprising a first power supply 50 that is an output type power supply connected to a drive system 600, a second power supply 30 that is a capacity type power supply, and a bidirectional DDC (power converter) 40 for performing bidirectional power transfer between the drive system 600 and first power supply 50 and the second power supply 30, and controls actuation of the bidirectional DDC 40. A running state acquisition unit 87 acquires information on a running state of a vehicle including vehicle stop or a running setting state. When the vehicle is in a predetermined running state or in the running setting state, a charging determination unit 83 makes a determination so that charging from the second power supply 30 to the first power supply 50 is performed by actuating the bidirectional DDC 40 when an amount of charge of the first power supply 50 is lower than an amount-of-charge threshold and the charging from the second power supply 30 to the first power supply 50 is stopped when the amount of charge of the first power supply 50 is equal to or higher than the amount-of-charge threshold.SELECTED DRAWING: Figure 1
【課題】次回走行時に備えて出力型電源の充電量を適切に確保する電源制御装置を提供する。【解決手段】電源制御装置80は、駆動システム600に接続される出力型電源である第1電源50、容量型電源である第2電源30、駆動システム600及び第1電源50と第2電源30との間で双方向に電力授受を行う双方向DDC(電力変換器)40を備える電源システム10に適用され、双方向DDC40の作動を制御する。走行状態取得部87は、車両停止を含む車両の走行状態又は走行設定状態に関する情報を取得する。車両が所定の走行状態又は走行設定状態のとき、充電判定部83は、第1電源50の充電量が充電量閾値未満の場合、双方向DDC40を作動させて第2電源30から第1電源50への充電を行い、第1電源50の充電量が充電量閾値以上の場合、第2電源30から第1電源50への充電を停止するように判定する。【選択図】図1
