CHARGE CONTROL DEVICE

A charge control device calculates a learning command value of a charging parameter used in a learning phase, operates a charger in the learning phase to control the charging parameter to the learning command value, calculates a learning temperature rise rate, based on the temperature of the secondary battery, calculates a charging-time temperature rise rate in a charging phase that follows the learning phase, prior to the start of the charging phase, based on a limit temperature of the secondary battery and a duration of the charging phase, calculates a charging command value of a charging parameter which is used during a period from the start to the end of the charging phase, based on the learning command value, the learning temperature rise rate, and the charging-time temperature rise rate, and operates the charger in the charging phase to control the charging parameter to the charging command value.
