摘　　要：针对航空锂电池安全保障问题,提出了一种基于等效电路模型的锂电池工作特性分析方法。该方法通过PNGV等效电路处理,实现对航空锂电池物理反应过程的电路模拟,并基于此研究了航空锂电池的工作特性。实验结果表明,该方法能够实现对航空用75 Ah锂电池等效电路的有效模拟,等效模型能够有效分析不同条件下的电池工作状态,获得锂电池工作特性规律,为锂电池的安全航空应用提供保障。An aeronautical lithium battery work character analysis method is proposed based on equivalent circuit model, aim- ing to solve its security guarantee problem. The method is realized by constructing the equivalent circuit processing, which realizes its equivalent circuit simulation. And the work character of the aeronautical lithium battery is studied based on this method. The ex- perimental results show that this method can achieve the equivalent circuit simulation of the aeronautical 75 Ah lithium batteries. The equivalent model can effectively analyze the battery work state under different conditions, providing the regular pattern of its operating characteristics. The proposed method provides security guarantee for the lithium battery aeronautical application.
