1. A battery package, comprising:
- a battery; and
a central processing unit (CPU) configured to;
determine that an integrated recharging time of the battery, at temperatures lower than a threshold temperature, exceeds a threshold;
set a recovery mode based on the determination that the integrated recharging time of the battery exceeds the threshold;
determine a first temperature of the battery in the set recovery mode;
control discharge of the battery at a first discharge rate in the set recovery mode, wherein the discharge is controlled based on the first temperature of the battery that is higher than the threshold temperature;
determine a second temperature of the battery;
control a heating operation to heat the battery for a determined time period, wherein the heating operation is controlled based on the second temperature that is lower than the threshold temperature;
determine a third temperature of the heated battery; and
control the discharge of the battery at a second discharge rate, based on the third temperature of the heated battery that is higher than the threshold temperature.
