To provide a charge control device and a charge control method that properly control power supply to a battery.SOLUTION: A charge control device according to the embodiment includes an estimation unit and a charge control unit. The estimation unit estimates a remaining battery level of an auxiliary battery that supplies electric power to auxiliary equipment mounted on a vehicle. The charge control unit controls charging/discharging the auxiliary battery based on the remaining battery level estimated by the estimation unit, gradually charges the auxiliary battery in a low capacity state where the remaining battery level is equal to or lower than the threshold value in which the charging of the auxiliary battery is restricted, and release the limiting condition when the remaining battery level is recovered to the threshold value.SELECTED DRAWING: Figure 2

    【課題】バッテリへの電力供給を適切に制御すること。【解決手段】実施形態に係る充電制御装置は、推定部と、充電制御部とを備える。推定部は、車両に搭載された補機類へ電力を供給する補機バッテリの電池残量を推定する。充電制御部は、推定部によって推定された電池残量に基づいて補機バッテリの充放電を制御するとともに、電池残量が閾値以下である低容量状態において、補機バッテリへの充電を制限した制限条件下において補機バッテリを徐々に充電し、電池残量が前記閾値まで回復した場合には、制限条件を解除する。【選択図】図2
