To provide a charging control system capable of suppressing an auxiliary battery from being over-discharged.SOLUTION: A vehicular charging control system using a solar panel includes: a solar battery; a driving battery; an auxiliary battery; and a controller for switching and controlling between a first charging mode for charging the solar battery with electric power generated by the solar panel and a second charging mode for distributing and charging electric power stored in at least the solar battery into the driving battery and the auxiliary battery at a predetermined ratio, based on an amount of storage of the solar battery. The controller, in the second charging mode, distributes electric power between the driving battery and the auxiliary battery at a first distribution rate as the predetermined rate when a voltage of the auxiliary battery is a predetermined value or more. When the voltage of the auxiliary battery is less than the predetermined value, the controller distributes electric power between the driving battery and the auxiliary battery at a second distribution rate whose rate of the auxiliary battery is higher than the first distribution rate as the predetermined rate.SELECTED DRAWING: Figure 1

    【課題】補機バッテリが過放電になることを抑制できる充電制御システムを提供する。【解決手段】ソーラーパネルを用いた車両用充電制御システムであって、ソーラーバッテリと、駆動用バッテリと、補機バッテリと、ソーラーパネルで発電された電力をソーラーバッテリに充電する第1の充電モードと、少なくともソーラーバッテリに蓄えられた電力を、駆動用バッテリ及び補機バッテリに所定の割合で配分して充電する第2の充電モードとを、ソーラーバッテリの蓄電量に基づいて切り替えて制御する制御部と、を備え、制御部は、第2の充電モードでは、補機バッテリの電圧が所定値以上のとき、所定の割合として、第1の配分割合で駆動用バッテリ及び補機バッテリに電力を配分し、補機バッテリの電圧が所定値未満のとき、所定の割合として、第1の配分割合よりも補機バッテリに配分する割合が高い第2の配分割合で駆動用バッテリ及び補機バッテリに電力を配分する。【選択図】図1
