Hybrid Electric Vehicles (HEVs) Technologies and Reinforcement Look ahead Energy Mangement

The major motivators for shifting to EVs are the need for reducing polluting engine emissions and reducing dependence on costly oil fuels. By the end of 2019, the global stock of EVs crossed the ten million mark. The growing acceptance of EVs is the outcome of several factors: technological advancements, rising storage capacity of traction batteries coupled with their falling cost, increased public charging facilities and Govt. incentives. The two EV technologies currently remain at the top are the battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEV). This paper gives an overview of various EV technologies, their features, limitations and challenges in their bulk deployment as a replacement to conventional vehicles
