For decades, the earth has been plagued by global warming. Although technology is rapidly evolving with the burning of fossil fuels to generate energy, resources are running in the opposite direction and greenhouse gases are being released into the surrounding atmosphere. Thus, the concept of renewable energy has gained the Simulink platform. With the rapid development of Lithium-Ion Battery Technology in the electric vehicle (EV) industry, the cell life of the battery is increasing dramatically. To convert ICE vehicles into electric vehicles it is important to build a battery pack for that vehicle. When building or upgrading a Battery pack we must consider many factors. tremendous their peace, environmental friendliness, and high efficiency. As the main source of energy for EVs, battery storage systems (BSSs) are important. Within this industry, Li-ion batteries are very popular in the EV industry. The purpose of this paper is to clarify the battery model for EVs and to upgrade to MATLAB.
