A Portable DC/DC Converter for Charge Transfer between Unevenly Rated Batteries in Electric Vehicle System

This research work has developed a novel DC-to-DC converter to transfer the energy between the unevenly rated batteries in electric vehicles during emergency times by using a boost converter. The proposed converter works in step-up mode to charge the high-rated battery with the low-rated battery. The step-up converter is developed by using the PIC Controller, PWM driver, MOSFET Switches, Diodes, and capacitors. In the existing method batteries with the same voltage ratings can be charged. By utilizing the proposed model, batteries with different voltage ratings can be charged. Moreover, the output is shown in LCD dis play, which displays the voltage and state of charge of both batteries.
