Abstract
The embodiment of the invention discloses a method and device for determining the starting current of an expansion valve in a low-temperature environment and electronic equipment, and the method comprises the steps: controlling the expansion valve to be started at a preset starting current, and determining whether a motor of the expansion valve is successfully started or not; when the expansion valve motor is not successfully started, the preset starting current is updated; and the expansion valve is controlled to be started with the updated preset starting current until an expansion valve motor is successfully started under the current preset starting current, and the current preset starting current is determined as the starting current of the expansion valve in the current environment. According to the technical scheme, the electronic expansion valve can be successfully started in the low-temperature environment, other components do not need to be additionally installed, the determining method is convenient and rapid, and the expansion valve can be started after the vehicle is started.
