The increased popularity of electric vehicles and e-mobility among the people, have encouraged many automotive companies and research organisations to develop good strategies for drivetrain designs involving batteries. As seen in the department of Alternative Powertrains research is carried out on hybrid fuel cell and electric vehicles. This thesis deals with the development of lithium ion battery model for electric vehicle simulations. A novel approach using black box modelling is developed for development of battery model using only the available battery measurements. Furthermore, a measurement test strategy is formulated providing the process direction and measurement parameters to be considered. Developed battery model provide voltage estimates for given Charge rate,temperature and State of Charge (SOC). The comparison of experimentally obtained and model estimated values. The model developed has a very good accuracy in estimation.
