A study on Fast-Charging Technologies and the influence of Battery Lifespan in electric vehicle

Abstract

The lifespan of batteries in electric vehicles becomes a major point in determining the overall performance, reliability, and cost-effectiveness of a vehicle. With the incorporation of EVs, it is now becoming increasingly important to comprehend that factors affect the degradation of the batteries. Fast charging is one key advantage offered with the alleviation of charging times as an essential requirement in modern EVs. Several key factors affect the lifespan of batteries in EVs such as variation in temperature, number of charging cycles, rates of discharge, depth of discharge, and the methods of charging, particularly fast charging. High charging currents and rapid thermal changes contribute to increased internal resistance and reduced overall performance through capacity fade. This paper consider the interaction of these factors in intricate detail and look into their collective effect on battery life. By studying these variables, this research is tasked with working towards understanding ways to optimize BMS, improve fast-charging protocols, and advance battery technologies. Ultimately, these efforts are essential to enhance the sustainability, reliability, and efficiency of EV batteries and thereby help to meet the increasing demands from consumers and the automotive industry.
