TECHNIQUES FOR ENHANCED BATTERY PACK RECHARGING

A method includes detecting that a battery pack requires charging and is currently operable for recharging. The method can identify a specific cell having a highest voltage in response to the detecting. The method can then recharge each cell of the battery pack to a predetermined voltage that is a s...

description A method includes detecting that a battery pack requires charging and is currently operable for recharging. The method can identify a specific cell having a highest voltage in response to the detecting. The method can then recharge each cell of the battery pack to a predetermined voltage that is a sum of (i) a maximum open circuit voltage of the specific cell and (ii) a voltage based on a resistance of and a first current supplied to the specific cell. When a temperature of the specific cell is less than a predetermined temperature or an age of the specific cell is greater than a predetermined age, the method includes recharging each cell to the predetermined voltage at less than the first current when (i) a predetermined period has elapsed or (ii) a voltage of the specific cell is less than a voltage threshold.
