To provide a vehicle power supply control device and a vehicle power supply system capable of appropriately heating a cabin and heating a catalyst according to an outside air temperature while optimizing mountability to a vehicle of the power supply system in a vehicle including heating heaters and a catalyst heater.SOLUTION: A vehicle power supply system is applied to a vehicle 10 including an engine 11, a power generator 17, a power storage device 18, an exhaust emission control catalyst 22, a catalyst heater 22A and heating heaters 46, 47, and includes: a request determination section that determines that both of a heating request and a catalyst heating request are made; a determination section that determines whether an outside air temperature is extremely cold lower than a predetermined low temperature value; and an electric power control section that preferentially supplies electric power from the power storage device to the heating heaters when both the heating request and the catalyst heating request are made and a determination is made that the outside air temperature is extremely cold, and preferentially supplies electric power from the power storage device to the catalyst heater when a determination is made that the outside air temperature is not extremely cold.SELECTED DRAWING: Figure 4

    【課題】暖房用ヒータと触媒ヒータとを備える車両において、電源システムの車両搭載面での好適化を図りつつ、外気温に応じて車室の暖房と触媒の加熱とを適正に実施できる車両電源制御装置及び車両電源システムを提供する。【解決手段】エンジン11と、発電機17と、蓄電装置18と、排気浄化用の触媒22と、触媒ヒータ22Aと、暖房用ヒータ46,47と、を備える車両10に適用され、暖房要求と触媒加熱要求とが共に生じていることを判定する要求判定部と、外気温が所定の低温値よりも低い極寒状態であるか否かを判定する判定部と、暖房要求と触媒加熱要求とが共に生じており、且つ極寒状態であると判定された場合に、蓄電装置から暖房用ヒータに対して優先的に電力を供給し、極寒状態でないと判定された場合に、蓄電装置から触媒ヒータに対して優先的に電力を供給する電力制御部と、を備える。【選択図】 図4
