Information Handling Systems And Improved Battery Charge Control Methods

Embodiments of information handling systems (IHSs) having rechargeable batteries and improved battery charge control methods are provided herein. For example, a method is disclosed for dynamically switching between a plurality of battery charging profiles, each having different recharge thresholds and charge termination thresholds for controlling battery recharge. Such a method may include detecting discharge current from a rechargeable battery of an IHS, determining whether or not the IHS is coupled to an external power source, and switching from using a first battery charging profile to using a second battery charging profile to recharge the rechargeable battery in response to detecting the discharge current while the IHS is coupled to the external power source and/or determining that the discharge current is a short term supplemental power event.
