Design and implementation of a high-efficiency on- board battery charger for electric vehicles with frequency control strategy

This paper presents a design and implementation of 3.3 kW on-board battery charger for electric vehicles or plug-in hybrid electric vehicles. A series-loaded resonant dc-dc converter and frequency control are adopted in consideration of efficiency, reliability, volume, cost, and so on. In order to obtain high efficiency and less volume within 6 liters, a prototype of the charger is designed and implemented by using high frequency of 80–130kHz and zero voltage switching method. The experimental result indicates 93% of the maximum efficiency and 5.84 liters in volume of the developed 3.3 kW on-board battery charger. Keywords-fuel cell electric vehicle; FCEV; low frequency current ripple; fuel cell; driving condition
