The invention provides an energy system control method of an electric locomotive and the corresponding electric locomotive, an energy system comprises a charger and two power battery packs connected in parallel, the charger charges and discharges the two power battery packs, and the control method comprises the following steps: setting a voltage difference threshold value of the two power battery packs; in the charging working condition, when the voltage difference between the two power battery packs is larger than a voltage difference threshold value, the charger charges the low-voltage power battery pack, and when the voltage difference between the two power battery packs is smaller than the voltage difference threshold value, the charger charges the two power battery packs at the same time; in the discharging working condition, when the voltage difference of the two power battery packs is larger than a voltage difference threshold value, the high-voltage power battery pack is discharged, and when the voltage difference of the two power battery packs is smaller than the voltage difference threshold value, the two power battery packs are discharged at the same time. One charger is used for charging the two power battery packs connected in parallel, so that the problem of power battery matching space waste caused by a large number of chargers is solved.

    本公开提供了一种电力机车的能源系统控制方法及相应的电力机车,能源系统包括充电机和并联的两个动力电池组,充电机为两个动力电池组进行充放电,控制方法包括:设置两个动力电池组的电压差阈值;充电工况:当两个动力电池组的电压差大于电压差阈值时,充电机为低电压的动力电池组充电,当两个动力电池组的电压差小于电压差阈值时,充电机同时为两个动力电池组充电;放电工况:当两个动力电池组的电压差大于电压差阈值时,高电压的动力电池组进行放电,当两组动力电池组的电压差小于电压差阈值时,两个动力电池组同时放电。通过使用一个充电机为并联的两个动力电池组充电,解决了充电机数量多造成动力电池匹配空间浪费的问题。
