Electric vehicles are playing a major role in pushing the world toward sustainability. Battery is the essential energy storage device in EVs and supercapacitor (SC) is added to improve the battery performance by reducing the stress during the transient period. The major issue in battery/SC pack is the imbalance in cell voltage that inherently occurred during manufacturing. The cell voltage imbalance of the energy storage pack leads to a fast discharge cycle, limits the charging voltage to a lower voltage level and limits the use of total pack energy. Hence, in this work, cell balancing technique is introduced for hybrid energy storage system with battery and SC for load support applications. Initially, the work analyzes the different cell balancing techniques for independent battery and SC pack. The independent cell balancing techniques are extended for active hybrid energy storage system and tested it for different load variations. Finally, detailed simulation and comparison between different topologies are presented to validate the study.
