Abstract
Sustainable transportation requires employability of electric vehicles (EVs). The battery powered vehicles are to compete with internal combustion engines in terms of run time, reliability and maintainability. Battery management system (BMS) deployed in electric vehicles are powered with monitoring and controlling key aspects of battery. Battery modeling plays a key role in adding the BMS with necessary parameters which helps in having a controlled and required level of charging and discharging of batteries and predicting the behavior of battery at harsher conditions like in electric vehicles. Various battery models were reviewed. Equivalent circuit model (ECM) for lithium ion battery was proposed. Proposed model was experimentally tested at different temperatures subjecting to different drive cycles and was validated. The work provides effective solution in replicating the battery behavior in real time considering EV applications
