Abstract
A battery management system calculates expected run time for the information handling system from either an average or instantaneous power consumption and the remaining battery capacity. When power is attached to the battery, the battery management system compares an expected run time with a current usage day profile. If the information handling system is operating in a non-active use period or if system run time can extend sufficiently into the non-use period then a slow charge rate is applied which will charge the batteries up to a substantially charged state (e.g., 80-95% of full capacity) and top off of the battery is deferred such that battery is fully charged somewhat before the average beginning of the next day (e.g., approximately one to two hours before the average beginning of the next day).
