Lithium-iron phosphate (LFP) batteries are widely used in electric vehicles (EVs) as flexible and clean sources of energy due to their high energy density per weight and size as well as their long battery life cycle when compared to other types of batteries. On the other hand, LFP batteries may become unstable and extremely dangerous if exposed to high temperatures in certain circumstances. Therefore, a battery cell model should be modeled and studied using an accurate and realistic model that reflects the actual behavior of the battery cells. This provides a high level of safety and performance. This work describes a method for modeling an electrical LFP battery cell model for an EV scenario using an equivalent resistor load. This method takes into account temperature differences and self-discharge effects during discharge. Through the use of both equations and block diagrams, the battery cell structure is presented and discussed in detail. Next, the battery model will be simulated and discussed to demonstrate how the battery performs according to temperature effects during a certain driving cycle. Throughout the paper, battery cell electrical and thermal characteristics are presented. Simulations are performed using the MATLAB programming language. Modeling of the battery cell is based on real experiments. Results of the proposed model are considered a pillar for EV battery simulations.
