Abstract:
A charge control device for an in-vehicle battery includes a control unit that obtains a neglect resistance increase rate as a reversible resistance component based on an SOC of the battery and a temperature of the battery when the battery is not charged/discharged, and that obtains a permissible charge current value to the battery based on the obtained neglect resistance increase rate.
