Cell equalization in battery stacks through State Of Charge estimation polling

  title={Cell equalization in battery stacks through State Of Charge estimation polling},
  author={Carmelo Speltino and Anna G. Stefanopoulou and Giovanni Fiengo},
  journal={Proceedings of the 2010 American Control Conference},
Differences in chemical characteristics, operating temperature or different internal resistance can cause differences in cell remaining capacity, leading to overcharging or overdischarging of respectively most charged and most discharged cells, decreasing the total stack storage capacity, shortening the battery lifetime and, eventually, permanently damaging the cells. The system proposed in this paper uses the switching capacitor method for cell equalization during bidirectional operations and… CONTINUE READING
