Abstract

This paper describes the design, fabrication and application of an electric vehicle diagnostic and rejuvenation system (EVDRS). This system is based on mosfet controlled thyristors (MCTs). In case when an electric vehicle (EV) (or a hybrid vehicle) starts losing quickly its power, this system will identify any failing battery(s) within the EV pack and will rejuvenate the whole battery pack without dismantling them nor unloading them from the EV. A novel algorithm to rejuvenate electric vehicle sealed lead-acid batteries is described. This rejuvenation extends the useful life of the batteries and makes the EV user-friendlier.
