Abstract
A charging control device includes a detector detecting a temperature of a battery; a controller causing the charger to stop charging the battery in response to the temperature of the battery falling outside a first range during the charging of the battery; an obtainer obtaining, from the charger, information that is capable of identifying a charging characteristic of the charger; a range setter setting the first range to be a temperature range that corresponds to the charging characteristic of the charger based on the information obtained in the obtainer.
Claims16
A charging control device, comprising:
- a battery pack that contains a battery;
- and
- a charger configured to charge the battery,
- wherein the battery pack includes:
- a detector configured to detect a temperature of the battery;
- a determiner configured to determine, during the charging of the battery by the charger, whether the temperature of the battery detected in the detector falls outside a first range, the first range including a first temperature as a minimum value and a second temperature as a maximum value;
- an obtainer configured to obtain, from the charger, identification information that is capable of identifying a charging characteristic of the charger;
- and
- a range setter configured to set at least one of the first temperature and the second temperature such that the first range is a temperature range that corresponds to the charging characteristic of the charger, the charging characteristic of the charger being indicated by the identification information obtained in the obtainer,
- wherein the charger includes a stopper configured to cause the charger to stop charging the battery in response to determining that the temperature of the battery falls outside the first range by the determiner.
