Patent ID: 8854012

Claim:
A computer-implemented method for managing use of a battery corresponding to a high-voltage lithium-polymer battery in a portable electronic device, comprising: monitoring a cycle number of the battery during use of the battery with the portable electronic device, wherein the cycle number corresponds to a number of charge-discharge cycles of the battery; monitoring a temperature of the battery during use of the battery with the portable electronic device; determining an optimal charge voltage for the battery that manages swelling in the battery by: if the temperature exceeds a temperature threshold, calculating the optimal charge voltage by incrementally reducing a first initial charge voltage based on a first cycle number threshold; if the temperature does not exceed the temperature threshold, calculating the optimal charge voltage by incrementally reducing a second initial charge voltage based on a second cycle number threshold, wherein the second cycle number threshold is higher than the first cycle number threshold; modifying a charging technique for the battery to charge the battery at the optimal charge voltage; monitoring a state-of-charge of the battery during charging of the battery; and if the battery remains in a fully charged state for longer than a time threshold, disconnecting the battery from a charger; and maintaining the disconnection as the battery self discharges and the state-of-charge of the battery voltage drops below the fully charged state; when the state-of-charge of the battery falls below a threshold state-of-charge, which is less than the fully charged state, resuming charging of the battery.
