Abstract: 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.

Abstract: A novel vehicle lighting control circuit for reducing the light intensity of a vehicle lighting element via pulse width modulation. A pulse width modulation adjuster is provided for producing a pulse width modulation control signal in order to operate the vehicle lighting element at a reduced light intensity. Such examples for use of the present invention include, but are not limited to, operation of: high beams at a low beam light intensity; daytime running lamps (DRLs); power balancing functions; and emergency lights.
