Fuzzy logic based supervisory energy management for multisource electric vehicles

This paper presents a fuzzy supervisory energy management system for multisource electric vehicles. The use of multiple energy storage devices such as batteries makes their management difficult and their maintenance costly. The proposed supervisory approach aims to equilibrate the state of charge (SOC) and hence energy usage, which extends the life of energy storage devices and reduces their heavy maintenance. The energy management strategy yields a high efficient operation of the overall system.
