Fast charging techniques for electrical vehicles using AC-DC

Abstract

The AC-DC quick charging method for electric vehicles (EVs) aims to increase power delivery and efficiency at charging stations. A shared rectification system, often a 12-pulse rectifier, is a critical component that improves power quality and decreases harmonics, making it ideal for high-power charging applications. This technique optimizes the overall stability and performance of the power network when paired with a DC side filter. An improved version of the Constant Current, Constant Voltage (CC-CV) approach reduces charging times while maintaining battery health, whereas the original CC-CV technique ensures safe battery charging. The experimental results demonstrate the possibility for faster and safer charging and validate the efficacy of the enhanced CC-CV approach. The system's scalability and integration of renewable energy sources further help sustainability goals. This technique not only increases consumer satisfaction, but it also fosters the development of effective, conveniently accessible EV charging infrastructure for the future
