The rapid electrification of transport and stationary energy systems has significantly increased the demand for lithium-ion batteries (LIBs) capable of enduring fast charging while maintaining long-term performance. However, conventional charging methods, particularly constant current–constant voltage (CC–CV), accelerate degradation mechanisms under high power demands. This paper proposes an adaptive, multi-stage fast charging protocol incorporating fuzzy logic control and thermal feedback to optimize charging current based on the battery's state of charge (SOC), internal resistance, and real-time temperature. Simulations based on electrochemical and thermal models in MATLAB/Simulink reveal that the proposed strategy significantly improves charge efficiency, reduces peak thermal stress, and extends cycle life by over 30% compared to standard CC–CV methods. These findings demonstrate a practical pathway for safer, faster, and longer-lasting battery operation in electric vehicles and energy storage systems.
