摘　　要：通过对失效电池不同充电容量、充电倍率下交流内阻的研究和大电流脉冲下直流内阻的研究,确定了快速判定MH-Ni电池是否失效的相关方法,并通过测量电池的内压和不同充电容量下的充电效率讨论了其有效性.Studied the inner resistance in different charge capacity and different charge magnification, researched the charge efficiency in different charge capacity, and measured the inner resistance at high rate. As a result, found some methods to quickly judge the fading of the MH-Ni cell. Explained why these methods came into existence by analyzing the inner structure and measuring the inner pressure in different charge capacity.
