Abstract: To improve the power balance efficiency of the lithium battery group, the authors propose a new high-efficiency active balance algorithm, which takes the shortest balance time as the target, uses the duty ratio dynamically adjust the equilibrium current value, reaches the optimal solution in each balance cycle,and realizes the efficient balance control of the battery group power.
Key words: battery group; active balance; model prediction; control algorithm
