The simulating mode cycle life characteristics of a 100 Ah Li-ion batteries using LiMn_2O_4 as cathode material for plug-in fuel cell hybrid electric bus at high temperature and high power condition were analyzed. The changing characteristics of capacity,efficiency,internal resistance and power capability of the batteries were obtained. It was found that state of charge(SOC)wor-king point was an important factor to the cycle life. At high temperature and high power condition,the corresponding driving distances in cycle life of the two batteries at the SOC working point of 0.3 and 0.5 were 17 400 km and 31 200 km,respectively.
