Lithium titanate oxide is considered as the most promising anode material for lithium-ion battery owing to its fast charging capability. Its charging profile is essential to be modeled with a simple battery model for battery charger design. This paper develops a universal mathematical battery model which can be fitted to the charging profiles of different charging rates by using genetic algorithm. The developed battery model has been validated from the experiment results. Comparison between simulation and experiment results for several charging rates are also presented. It is envisaged that the proposed model can be used to develop a universal battery charger for different battery capacity. This will eventually accelerate the development of energy storage system in green technology application.
