An overview of power electronics in electric vehicles

TLDR

Growing energy costs, dependence, and environmental concerns, coupled with stringent zero‑emission regulations worldwide, have spurred rapid expansion of the electric‑vehicle market and accelerated development of power‑electronics technology. This paper reviews the current status of multidisciplinary technologies in electric vehicles. The authors examine challenges in power‑electronics for EV propulsion, battery charging, and power accessories.

Abstract

In response to concerns about energy cost, energy dependence, and environmental damage, a rekindling of interest in electric vehicles (EVs) has been obvious. Based on the "California rules" on zero emission vehicles in the United States, as well as similar tightened air pollution regulation in Europe, Asia, and much of the rest of the world, the market size of EVs will be enormous. Thus, the development of power electronics technology for EVs will take an accelerated pace to fulfil the market needs. This paper reviews the current status of multidisciplinary technologies in EVs. Various challenges of power electronics technology for EV propulsion, battery charging, and power accessories are explored.
