Investigation on Electric Vehicle EV Battery cooling system using different Phase change materials

Abstract

newlineElectric vehicles (EVs) have grown in popularity due to their zero emissions and newlinehigh vehicle efficiency.Electric vehicle certified and real-world energy consumption increase newlineby 60% and 40%, respectively, with each doubling of vehicle mass, but only by newline5% with each doubling of rated motor power. Battery capacity and vehicle mass are intimately newlinelinked. A 10 kWh increase in battery capacity increases electric car mass by 15 newlinekg, drive range by 40 50 km, and energy consumption by 0.7 1.0 kWh/100 km. Stateof- newlinethe-art mass-produced electric passenger cars are 2.10.8 kWh/100 km more efficient newlinethan first-generation vehicles produced on a small scale Weiss et al. (2020). However, newlineseveral challenges, including the battery s performance, cost, lifetime, and safety, limit newlinethe electric vehicle s growth. As a result, protecting the batteries monitoring and management newlineis necessary to ensure optimal performance when running a vehicle in a wide newlinerange of conditions. newlineOn the current automobile market, there are various combination levels of hybrid newlineelectric vehicles and pure electric vehicles available. Various sizes, types, and the newlinenumber of battery cells are mounted in EVs depending on the blending level. Unlike newlinetraditional fuel, battery cells as an energy source have stringent working environment newlinerequirements. They are extremely temperature-sensitive. A Battery Thermal Management newlineSystem (BTMS) is typically integrated with battery cells to ensure a proper thermal newlineworking environment. Thus, understanding the proper working requirements of newlinea battery, as well as what types of management systems can adequately and efficiently newlinemeet these requirements, is critical. With this base, the performance of a battery pack in newlinean electric vehicle can be maximized. This research proposes two thermal management newlinesystems for the passive and forced air cooling coupled PCM. newlineThe scope of this research is to use Computational Fluid Dynamics (CFD) and experiments newlineto reduce the temperature distribution area in Li-ion cells and the battery newlinepack over time an
