Abstract
A method for use with a vehicle battery pack, where the method determines a voltage threshold that may prevent the vehicle battery pack from being overcharged. The voltage threshold may be a dynamic threshold that changes or adjusts over time in order to accommodate changing conditions in the vehicle battery pack, the vehicle and/or the surrounding environment. The method may consider one or more battery readings when determining the voltage threshold, including temperature, voltage and/or current readings. According to one embodiment, the method is designed to accommodate high-current, short-duration charging events, like regenerative breaking.
