Review of Fast Charging Strategies in Lithium-Ion Battery Electric Vehicles

This paper presents a comprehensive review of lithiumion battery fast-charging strategies for Battery Electric Vehicles (BEVs), focusing on key battery chemistries, and their associated aging mechanisms. The study classifies and compares key charging methods, including Constant Current Constant Voltage (CCCV), Boost Charging (BC), Constant Power Constant Voltage (CPCV), Varying Current Decay (VCD), and Multi-Stage Constant Current (MCC). It emphasizes optimized MCC, which uses adaptive algorithms to balance fast charging with battery aging. Findings indicate that optimized MCC offers the optimal trade-off in terms of speed, efficiency, and longevity, positioning it as a leading strategy for future BEV charging systems.
