Abstract

It has been observed that the Electric vehicles production is increasing rapidly as it will be a substitute for the usage of fossil fuels. The objective is to minimize usage of fossil fuels to reduce pollution as well as the cost of refueling the vehicle with efficient and reliable chargers. The Charging of an Electric Vehicle is still an open problem regarding its performance. Hence, the charging technologies and their improvements can be tailored by increasing the efficiency of battery charging and adjustable charging voltages. A DSP controller-based off-board battery charger with a three-stage AC-DC charger is presented in the study. To serve it, a step-up AC-DC converter with power factor correction for line regulation and a full-bridge phase-shifted DC-DC converter is placed in the circuit with a transformer and a full bridge rectifier at the output end. The addressed scheme is having external feedback from the battery to a DSP controller that senses battery voltage and charges the battery accordingly. The presented simulated and hardware results are verified and compared to conventional chargers. The results are attaining the charging efficiency up to 94% at different voltage levels.
