High-Performance Lithium Polymer Battery Pack for Real-World Racing Motorcycle

This paper deals with the qualification testing to design a battery pack for a fully electric racing motorcycle. To obtain the best performance from the cells and considering the point that in this case the battery pack will be used in special racing condition, finding the best configuration and cells sequence to be connected together in that’s configuration is very important to make the battery pack. To avoid impedance mismatching inside the modules and the final pack, electrochemical impedance spectroscopy, capacity test, and impulse current test has been used to select appropriate cells to be connected in strings and make a uniform and high-performance battery pack with the best configuration based on the categorized cells. Experimental results obtained from the cell to cell variation and also impedance measurement for each module prove the uniformity in impedance.
