Abstract

This project is about the design, fabrication and application of an on-board diagnostic and rejuvenation system. This system is based on MOSFET controlled thyristors (MCTs). In the case when an electric vehicle (EV) starts loosing quickly its power, this system is designed to identify any failing battery(s) within the EV pack and to rejuvenate the whole battery pack without dismantling them and unloading them from the EV. A novel algorithm to rejuvenate electric vehicle sealed lead acid batteries is described. This system is being used at The Center of Electric Vehicles and the University of Massachusetts Lowell. It extends the useful life of the batteries and makes the EV user-friendlier.
