Abstract: Batteries and associated charging conditions or other operating conditions are evaluated by a computational model that classifies or characterizes the battery and associated conditions. Such battery model may classify batteries according to any of many different considerations such as whether the conditions are safe or unsafe or whether the conditions are likely to unnecessarily degrade the future performance of the battery. In some cases, the battery model executes while the battery is installed in an electronic device such as a smart phone or a vehicle. In some cases, the battery model executes and provides results (e.g., a classification of the battery) in real time while the battery is installed and being charged.
