9.4 Balancing Control Strategy

In different balancing control protocols, control algorithms based on selected state variables are utilized to maintain the SOC inhomogeneities within a certain range. The studies on control protocols involve the selection of state variable and control algorithm development. Control protocols are affected by factors such as sampling accuracy, response characteristics, system robustness and hysteresis. Without suitable control protocols, the system may not be balanced or overbalanced and adverse effects arise such as energy loss, reduced lifetime and thermal runaway. Choosing correct state variables and robust algorithms for balancing control will improve balancing control performances.
