The replacement cost accounts for a large proportion of the economic cost in the whole life cycle of shunting locomotive. Therefore, accurate calculation of the replacement cost of multi-energy drive system plays an important role in optimizing the configuration and reducing the economic cost. The diesel generator set can basically meet the energy supply demand of a fixed number of years, therefore, the replacement times in the 32 years’ life cycle are generally two, and the core problem is to calculate the replacement cost of the power battery pack. In this paper, a V-shaped closed-loop counting method is used. On the premise of knowing the SOC(state of charge) curve of the battery, a model is established to calculate the DOD(depth of discharge) of the power battery pack, so as to obtain the replacement times of the power battery pack. Combined with the initial purchase cost, the replacement cost of the energy storage system is calculated. The results show that under the existing configuration, it is 6 times of the initial purchase cost.
