Abstract
A method for determining state of charge (SOC) of an electrochemical device using fuzzy logic (i.e., an intelligent system) is presented. State of charge of an electrochemical device is determined by an internal characteristic or parameter (or external operating and environmental conditions) with an intelligent system. The electrochemical device comprises such devices as primary ('throwaway') batteries, rechargeable batteries, fuel cells, a hybrid battery containing a fuel cell electrode and electrochemical supercapacitors. The intelligent system is trained in the relationship between the characteristic of the electrochemical device and the SOC of the electrochemical device.
