Repairable: Can often be resolved via the BMS (Battery Management System) balancing function or manual charge/discharge adjustments. No need to discard: Safe for continued use after routine maintenance. For instance: Variations in capacity and impedance create uneven cell currents. Battery balancing is a crucial aspect of ensuring the optimal performance, longevity, and safety of your lithium battery systems. This critical issue affects 23% of industrial energy storage systems according to 2023 NREL data, making it a hot topic for engineers and proc. Homemade battery packs, in particular, may start unbalanced, even when using batteries from the same batch, and balancing the cells is recommended. A Li-ion battery pack consists of multiple cells connected in series.
