The battery performance of electric wheelchairs was measured under indoor and outdoor conditions, and simulated driving cycles for these two environments were derived from these tests. Driving cycles were used to bench-test deep discharge wet cell and gel cell lead-acid batteries, nickel-cadmium batteries, and experimental nickel-zinc batteries. Results of this study support the conclusion that...

The characteristics of lead-acid batteries for wheelchairs in terms of a new empirical equation for the capacity, application of the Palmgren-Miner Rule for sizing the battery, and the effect of depth of discharge on the life cycles is presented. A brief section about selecting an economical battery for an electric wheelchair is included.

A Radial Basis Function based learning system method has been proposed for estimation of State of Charge (SOC) of lead Acid battery. Coulomb metric method is used for SOC estimation with correction factor computed by Radial Basis Function method. Radial Basis function based technique is used for learning battery performance variation with time and other parameters. Experimental results are incl...

Acknowledgement I would like to acknowledge my thesis supervisor, Dr. Greg Crebbin for providing guidance and for helping me to define my research topic, constantly asking me the tough questions. Authors, who have made past contribution to this topic of research and in turn, helped me to formulate my own thesis understanding. Finally, to my family and friends who have provided much needed moral...
