Abstract
A method, system, and integrated circuit are provided for monitoring a battery within a host device for abnormal conditions. A first temperature is determined for a battery at a first state-of-charge (SOC) of the battery during a charge action. A second temperature for the battery at a second SOC of the battery during the charge action is determined, and a current delta-SOC for the charge action is determined. A memory in the host device holding delta-SOC temperature data associated with a plurality of delta-SOCs is accessed. Based on this, a determination is made as to whether a battery temperature increase for the charge action at the current delta-SOC is abnormal, the delta-SOC temperature data including at least first data associated with a normal battery performance profile and second data associated with an abnormal battery performance profile.
