The invention relates to an electronic expansion valve control method and device and a controller. The method comprises the steps that the environment temperature and vehicle speed information of a target vehicle at the current refrigeration moment are obtained, and the battery refrigeration duration of the target vehicle is obtained; the battery refrigeration duration is the duration from the initial refrigeration moment of the battery of the target vehicle to the current refrigeration moment; according to the environment temperature and the vehicle speed information, the basic opening degree and the composite opening degree of an electronic expansion valve of the target vehicle at the current refrigeration moment are obtained, and according to the vehicle speed information, the opening degree adjusting speed of the electronic expansion valve at the current refrigeration moment is obtained; according to the basic opening degree, the composite opening degree, the opening degree adjusting speed and the battery refrigeration duration, the target opening degree of the electronic expansion valve at the current refrigeration moment is obtained; the target opening degree is used for controlling the opening degree of the electronic expansion valve at the current refrigeration moment to be adjusted to the target opening degree. By means of the method, the opening adjustment delay of the electronic expansion valve can be reduced.
