I. Introduction
The electric vehicle (EV) charging is conventionally done through type-1 and -2 (single/three-phase) ac on-board slow chargers with the power range of 3.3–19.4 kW. A comprehensive review of bidirectional topologies with single/two-stage rectification with power factor correction for on-board chargers in the commercial EVs is discussed in [1] and [2]. Detailed comparison of type-1, -2, and the dc fast-charging stations with respect to charging time, power density, power level, cost, and review of recent typologies for conventional and future charging methods is discussed in [3] and [4]. Furthermore, high power (>50 kW) external off-board dc fast-charging stations are established to charge EV batteries, with a charging time of less than an hour [5]. In spite of these conventional EV charging methods, the EV users are experiencing range anxiety due to limited charging infrastructure [6].
