摘　　要：针对铁路客车用串联电池组中各电池单体均有出现接地的可能,该文提出多点接地的模型和电池组大漏电流的概念,推导了大漏电流的位置、测量方法及其表达式,对电池组的接地问题进行研究。MATLAB/Simulink的仿真结果和实验测试数据证明了该文采用的模型、测量方法和推导过程的正确性。Based on multi--point grounding model of battery packs, maximum leakage current and concept of battery equivalent grounding resistance, measurement method and expression under multi--point grounding model are proposed in this paper, and also study on the issue of battery grounding. Simulation result by Matlab/Simulink and test data by experiment validate the model, measurement method and process of deriving adopted in this paper.
