Abstract

Range anxiety, lack of charging systems and cost are the main concerns for fast adoption of electric vehicles (EVs). Battery chargers decide the performance and life cycle of the battery packs. Therefore, battery chargers play a vital role to escalate the penetration of the Plug-in EVs (PEVs). PEV battery chargers are classified into onboard and off-board chargers based on its availability inside or outside the vehicle. Onboard chargers do not need any additional infrastructure, which can be easily and directly charged from the ac mains. This paper aims to review the technological status of onboard charging infrastructure including front-end power factor correction (PFC) converters and the battery interface converters. The merits and demerits of all the charger topologies are discussed in detail. Finally, a single-phase 1.4 kW onboard charger with interleaved boost PFC as a front-end converter and phase-shifted full-bridge converter as a battery interface is designed and simulated in the PLECS software platform.
