Abstract

An intelligent battery management method (300) and device (600). The method (300) can include the steps of: monitoring (310) parameters including at least a wireless communication device battery temperature and battery state of charge and a dock battery state of charge; comparing (320) the monitored parameters with a decision matrix; and enabling (330) at least one of charging and cooling a wireless communication device battery based on the compared parameters and the decision matrix. The method (300) can provide active charging and cooling, which can help to prolong the useful life of a battery and provide a maximum recharging capacity.

Claims
