Nonisolated Electric Vehicle Chargers: Their Current Status and Future Challenges

Transportation electrification has been gaining momentum in the past two decades. Ground vehicle electrification is the front-runner of this paradigm shift as electric vehicles slowly but steadily penetrate the consumer market. Besides higher costs, one of the main concerns related to vehicle electrification is range anxiety, which is the result of the limited accessibility of charging ports and stations as well as the relatively low energy density and cycle life of batteries. Lower cost, higher power, and more accessible battery chargers are among potential solutions to address the expense and range anxiety issues.
