Reconfigurable Battery Systems for Enhanced Fast Charging in Electric Vehicles

Abstract: The adoption of electric vehicles (EVs) is rapidly growing as a key solution to reducing greenhouse gas emissions. However, prolonged charging times remain a significant barrier to widespread EV usage, especially for individuals without access to fast charging infrastructure. This paper explores the potential of reconfigurable battery systems to reduce EV charging times without compromising battery life. We propose innovative battery pack configurations that dynamically adjust the arrangement of cells to optimize charging performance. Simulations were conducted using MATLAB and Simulink to compare the efficiency of various battery configurations, focusing on charging times, state of charge (SOC), voltage, and current under different conditions. The results demonstrate that connecting more batteries in series through reconfigurability in battery packs can significantly reduce charging times while maintaining operational safety. This study offers insights into how reconfigurable battery designs can provide a practical solution for faster, more efficient home-based EV charging, making EV ownership more accessible and sustainable.
