Electric Vehicles have become the need of time to reduce the pollution from the transportation sector. Not only they reduce pollution but they are also excellent products of renewable energy. Two of the most eminent parts of any electrical vehicle are the Battery and Battery management systems(BMS). Modeling and testing of the systems using simulation is an effective method alternate to hardware testing since it reduces the cost and increases the efficiency of testing. The hardware testing of the battery also affects the safety of the system and any errors may lead to permanent damage to the components and sometimes affecting the people operating them. To model and simulate any component it is necessary to analyze the effects of the parameters which influence it. In this paper, the effect of temperature and the number of RC pairs taken to model the equivalent circuit of the battery is considered as the key factors. The results are used for the analysis of their effects in real-time using the simulation models.
