Summary: The lack of infrastructure and rising battery material prices challenge the success of electric vehicles globally, making internal combustion engine vehicles (ICEVs) still popular. To address the short lifespan and low storage capacity of traditional lead-acid batteries (LABs), a hybrid energy storage system (HESS) with an integrated fuzzy-logic and triple-loop-proportional-integral-based battery management strategy (BMS) is proposed. The results demonstrate improved LAB performance and superior storage capacity compared to single use of LABs.
