The invention discloses a control method, device and equipment for a vehicle electronic expansion valve, a storage medium and a vehicle. The control method comprises the steps that the battery temperature of the whole vehicle and the first side pressure value of a compressor are obtained; the basic opening degree of the electronic expansion valve is determined according to the battery temperature, the first side pressure value and an opening degree characteristic table of the electronic expansion valve; determining an actual increase rate of the first side pressure value according to a relationship between the first side pressure value and a first threshold value; determining a first corrected opening degree of the electronic expansion valve according to the actual increase rate of the first side pressure value; and the final opening degree of the electronic expansion valve is determined according to the basic opening degree and the first correction opening degree. According to the control method of the vehicle electronic expansion valve, the opening degree of the electronic expansion valve is corrected based on the external environment temperature, the battery temperature and the high-pressure side pressure value of the compressor, when the battery has the temperature rising trend, the opening degree of the electronic expansion valve is controlled in advance, and the optimal cooling effect is achieved.
