Abstract:

This work uses War Strategy Optimization (WSO) to build a new hybrid design for electric vehicle bidirectional DC DC converters with high conversion ratios. Low voltage load on semiconductors, high voltage conversion ratios, a steady current at the low voltage port, and a steady potential differential between the lower voltage and the high voltage ports' grounds are some of the features of the suggested converter. The converter's efficiency is raised by using synchronous rectification. The primary benefit of the suggested structure is that it may be utilized with various energy sources with various voltage-current characteristics. Furthermore, the battery may be charged in breaking mode because of the bidirectional nature of the proposed design. New energy automobiles are increasingly using the method for energy storage that is a hybrid of "fuel cell/power battery plus supercapacitors" to improve the powertrain's longevity and dynamic performance. This converter is a great substitute for DC-DC converters because of its high voltage gain and the aforementioned characteristics for electric vehicles. The WSO approach showed that charge prices dropped by 12.45% and 3.61%, respectively, while waiting times dropped by 11.17% and 39.09%; these findings imply that the WSO algorithm has the potential to increase both the efficacy and affordability of EV management systems, particularly in scenarios with inadequate charging infrastructure. The charge and discharge states can produce the highest efficiency, 98%, respectively, based on experimental results.
