The invention relates to a control method and device of a hybrid power locomotive and a computer readable storage medium. The control method comprises the following steps of calculating the total current of an intermediate loop according to the power target value of a main generator and the intermediate voltage of the intermediate loop; calculating a current distribution coefficient of each charging branch according to the charge states of multiple power battery modules, wherein each power battery module corresponds to one charging branch; calculating a first charging current target value of each charging branch according to the total current and the current distribution coefficient; comparing the first charging current target value with a second charging current target value of the corresponding power battery module to determine a smaller value of the first charging current target value and the second charging current target value, wherein the second charging current target value is provided by a battery management system of the corresponding power battery module; and in response to the fact that the smaller value of each charging branch is the first charging current target value,taking the smaller value of each charging branch as a charging current control target value, and charging each corresponding power battery module.

本发明涉及一种混合动力机车的控制方法及装置，以及一种计算机可读存储介质。该控制方法包括步骤：根据主发电机的功率目标值及中间回路的中间电压，计算中间回路的总电流；根据多个动力电池模块的荷电状态，计算每条充电支路的电流分配系数，其中，每个动力电池模块对应一条充电支路；根据总电流及电流分配系数，计算各充电支路的第一充电电流目标值；将第一充电电流目标值与对应动力电池模块的第二充电电流目标值进行比较以确定两者的较小值，其中，第二充电电流目标值由对应动力电池模块的电池管理系统提供；以及响应于各充电支路的较小值都为第一充电电流目标值，则以各充电支路的较小值为充电电流控制目标值，向各对应动力电池模块充电。
