Active Cell Balancing using Multi-winding Forward Converter for Lithium-ion Battery

Nowadays, Electric Vehicles (EVs) are the most important booming technologies. They are called as the Future of Driving. Adoption of Electric Vehicles (EVs) is quite challenging in present times due to the lack of compact size of the batteries, and lack of maintenance and service. This paper presents the Active Cell Balancing technique using a Multi-winding Forward Converter. This improves the battery pack's capacity, effectiveness, battery life, and overall performance. The proposed model uses MOSFET as a switch and high frequency switching transformer where the primary and secondary windings of the transformer are isolated. Through switching, the total voltage of all the cells on the secondary windings is transferred to the primary windings. The average amount of energy from the primary winding is redistributed to each connected cell on the secondary winding. The proposed model's cell balancing time is obtained through simulation using the MATLAB Simulink Environment.
