A non-isolated DC-DC converter with high voltage gain capability is developed to charge electric vehicle (EV) batteries, addressing the increasing adoption of EVs driven by environmental considerations. The proposed high-gain DC-DC converter employs a switched capacitor technique, achieving an input voltage of 7 V, an output voltage of 49 V, and a voltage gain of 7. The design offers high efficiency, reduced stress on switches, and operates at a low duty cycle, enhancing its overall performance. In contrast to the typical high-gain conventional converter, the proposed high-gain converter topology has low losses as compared to other converters. For the proposed high-gain DC-DC converter, the switched capacitor technique increases the output voltage because of periodic turn-on and periodic discharging of the capacitor. The proposed high-gain DC-DC converter for the non-ideal model is thoroughly examined. The proposed system uses the coulomb counting method for SoC estimation during the charging of the EVs battery.
