Abstract:
1. A battery pack comprising: an obtaining unit configured to obtain computation information for calculating a charge current, the computation information including temperature information of a battery; a computation unit configured to compute a charge current for the battery based on the computation information, the computation unit configured to set the charge current to a first current if the temperature is between a first temperature and a second temperature and the voltage is above a first voltage, to set the charge current to a second current less than the first current if the temperature is between a third temperature and a fourth temperature and not between the first temperature and the second temperature, and to set the charge current to a third current if the temperature is between the first temperature and the second temperature and the voltage is below the first voltage, where the third current is greater than the first current; and a notification unit configured to notify a computer of the charge current computed by the computation unit.
