Method and system for charging batteries with improved cycle life
First Claim
1. A battery charging method, comprising the steps of:
- determining that a battery is attached to a batters charger;
setting a maximum charge voltage for the battery; and
dynamically adjusting the maximum charge voltage for the battery while the batter is attached to the battery charger based on at least one among an amount of time the battery is maintained at the maximum charge voltage while attached to the battery charger and an amount of cycles the battery is charged to the maximum charge voltage while attached to the battery charger.

Abstract
A battery charging method (20) can include the steps of setting (20) a maximum charge voltage for a battery (104) and dynamically adjusting (38) the maximum charge voltage for the battery based on at least one among an amount of time the battery is maintained at the maximum charge voltage and an amount of cycles the battery is charged to the maximum charge voltage. The method can further include the step of measuring (36) a temperature of the battery and further dynamically adjusting (38) the maximum charge voltage for the battery based on the temperature of the battery, and/or timer value and/or counter value. Furthermore, the method can also include the step of updating (130) at least one among a counter and a timer each time after a charge is complete.

8. A battery charging method, comprising the steps of:
-
setting a maximum charge voltage for a battery;
setting a threshold for at least one among a timer and a counter;
setting the at least one among the timer and the counter to zero for each time that the battery is coupled to a battery charger;
charging the battery to the maximum charge voltage;
incrementing the at least one among the timer and the counter when charging of the battery is complete;
repeating the charging and the incrementing steps while the battery is coupled to the battery charger in response to a battery voltage for the battery falling below a recharge voltage threshold and the at least one among the timer and the counter failing to exceed the threshold; and
adjusting the maximum charge voltage and repeating the charging and the incrementing steps while the battery is coupled to the batten charger in response to the battery voltage for the battery falling below the recharge voltage threshold and the at least one among the timer and the counter exceeding the threshold. - View Dependent Claims (9, 10, 11, 12)
