Optimising the structure of a cascaded modular battery system for enhancing the performance of battery packs (2019)
Journal Article
Fares, A. M., Klumpner, C., & Sumner, M. (2019). Optimising the structure of a cascaded modular battery system for enhancing the performance of battery packs. Journal of Engineering, 2019(17), 3862-3866. https://doi.org/10.1049/joe.2018.8228

The overall performance of battery packs may be affected by imbalances between the series connected cells which is more likely in packs with high number of cells needed to provide a high voltage as needed for example in electric vehicles. In this cas... Read More about Optimising the structure of a cascaded modular battery system for enhancing the performance of battery packs.
