Abstract
A battery pack includes: an obtaining unit for obtaining computation information for calculating a charge current including temperature information of a battery; a computation unit for computing a charge current for the battery based on the computation information; and a notification unit for notifying a computer of the charge current computed by the computation unit. The notification unit uses a dedicated command to notify the computer of the charge current. The battery pack includes: a storage unit for storing therein a first threshold value and a second threshold value relating to the temperature information, and the computation unit may compute the optimal charge current depending on which of ranges divided by the first threshold value and the second threshold value the temperature information belongs to.
