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.

Summary: Hybrid and electric vehicles are seen as solutions to environmental problems in transportation caused by fossil fuel use. However, there are challenges in terms of battery costs, energy consumption, and charging times. This research proposes a method for estimating battery and charging slot requirements for fleets of hybrid or electric motorcycles using discrete event simulation. The results allow for the identification of a design basis for battery swapping stations, where waiting times stabilize regardless of the number of vehicles in circulation. The study also shows a relationship between the number of batteries, charging slots, and battery cycles, which vary depending on the motorcycle technology.
