Abstract
<div class="section abstract"><div class="htmlview paragraph">To achieve CO2-neutral mobility, various OEMs are launching Heavy Duty (HD) Electric Vehicle (EV) throughout the globe. HD EVs are equipped with high-power battery packs to sustain intercity trips in laden conditions. Compared to passenger EVs, commercial EVs require higher charging duration due to high-capacity batteries with existing CCS charging standard. This results in increased trip duration low power charging and overnight charging will result in higher idle time therefore decreasing the effective vehicle utilization. To mitigate these challenges, CharIN proposes Megawatt Charging System (MCS) in SAE J3271. This paper aims at providing a comprehensive analysis between the Megawatt Charging System and Combined Charging System. In addition to this, this paper emphasis the hardware and software changes required in the Charging Control Unit (CCU) to meet SAE J3271 standards and hardware solutions to operate the vehicle within its respective thermal limit during megawatt charging.</div></div>
