The invention discloses a range extender control method and device and a computer readable storage medium, and the method comprises the steps: controlling a range extender to enter an idling mode when a shutdown condition is satisfied; the temperature of engine coolant in the idling mode is obtained; when the temperature of the engine coolant is larger than or equal to a preset temperature value, a generator is controlled to drag the engine to rotate forwards so as to reduce the temperature of the engine coolant; and when the temperature of the engine coolant is smaller than the preset temperature value, the range extender is controlled to execute shutdown operation. In the idling mode, due to the fact that the engine is dragged by the generator to rotate forwards to reduce the temperature of the cooling liquid of the engine, the cooling liquid temperature reducing efficiency in the idling mode is improved, and engine parts are prevented from being damaged by too high water temperature in an engine cylinder. And meanwhile, when the temperature of the cooling liquid is lowered and meets the requirement, the range extender is controlled to stop, the problem that oil consumption is increased due to the fact that the range extender is in the idling mode for a long time is solved, and the fuel economy of the range extender is improved.
本发明公开了增程器的控制方法、设备及计算机可读存储介质,该方法包括:在满足停机条件时,控制增程器进入怠速模式;获取所述怠速模式下的发动机冷却液温度;在所述发动机冷却液温度大于或等于预设温度值时,控制发电机拖动所述发动机正转,以降低所述发动机冷却液温度;在所述发动机冷却液温度小于所述预设温度值时,控制所述增程器执行停机操作。在怠速模式下,由于通过发电机拖动发动机正转降低发动机冷却液温度,提高怠速模式下冷却液温度的降低效率,避免发动机缸内水温过高对发动机零部件的损坏。同时,在冷却液温度下降符合要求时,控制增程器停机,避免增程器长时间处于怠速模式导致油耗增加的问题,提高增程器的燃油经济性。
