Abstract:
A method for charging a battery pack for an electric vehicle charges at a preselected maximum charging current until the battery pack voltage reaches a reference voltage level. The battery pack is then charged while maintaining the reference voltage until the charging current decreases to a first reference current level. Charging continues at the first reference current level until a time rate of change of the battery pack voltage reaches a first reference time rate of change. The battery pack voltage is determined and whenever the battery pack voltage is less than a decision voltage reference level, the battery pack is further charged at a second reference current level until the time rate of change of the battery pack voltage reaches a second reference value. A manually initiated pack recovery charge routine is also provided to address new battery pack installations.
