To provide a power supply controller for preventing power of an output type power supply from being consumed wastefully before becoming a high load state.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 power supply amount calculation unit 81 calculates command power being a command value for a power supply amount of the first power supply 50 and the second power supply 30, on the basis of power of the first power supply 50 and the second power supply 30 and request power from a vehicle. A power converter operation unit 84 operates the bidirectional DDC 40 according to the command power. For the request power from the vehicle, the power supply amount calculation unit 81 calculates the command power so that a power supply amount from the second power supply 30 is larger than a power supply amount from the first power supply 50.SELECTED DRAWING: Figure 1

    【課題】高負荷状態になる前に出力型電源の電力が無駄に消費されることを防止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。電力供給量算出部81は、第1電源50及び第2電源30の電力、並びに、車両からの要求電力に基づいて、第1電源50及び第2電源30の電力供給量の指令値である指令電力を算出する。電力変換器操作部84は、指令電力に従って双方向DDC40を操作する。電力供給量算出部81は、車両からの要求電力に対し、第1電源50からの電力供給量に比べ第2電源30からの電力供給量が大きくなるように指令電力を算出する。【選択図】図1
