Method for determining success of icebreaking start-up of hydrogen circulating pump and icebreaking start-up device

The invention discloses a successful judgment method for icebreaking start of a hydrogen circulating pump, which judges whether a motor is successfully started or not by calculating a theoretical voltage value of a motor of the hydrogen circulating pump and comparing an actual voltage value of the motor with the theoretical voltage value of the motor. The overall control method is simple, and the ice breaking starting efficiency and the judgment accuracy of whether ice breaking is successful or not can be improved. 本发明公开一种氢气循环泵的破冰启动的成功判定方法，其通过计算氢气循环泵的电机的理论电压值，并获取电机的实际电压值与电机的理论电压值比较，以判定电机是否已成功启动。其整体控制方法简单，能够提高破冰启动的效率及成功与否的判定准确率。
