Abstract: Aiming at the inconsistency of electric vehicle series batteries in the circuit, this paper first elaborates the causes of inconsistency of the lithium titanate battery pack and the equalization method. Then, through a comparative study of active and passive equalization, a voltage-based passive equilibrium control strategy is designed based on speci c needs, using the tool of Matlab / Simulink to build a model of battery equilibrium strategy. Finally, the follow-up simulation experiment veri es the effectiveness of the proposed equilibrium control strategy. |
