Operation control method and device, external air conditioner and computer storage medium

Abstract

The invention provides an operation control method and device, an external air conditioner and a computer storage medium. The operation control method of electrical equipment comprises the following steps: detecting the environment temperature of a load; configuring a current limit value of a power device according to the environment temperature; and according to the relationship between the operation current of the power device and the current limit value, controlling and adjusting a switch control signal of the power device to make the adjusted switch control signal suitable for enabling theoperation current to be smaller than or equal to the current limit value. The temperature of the power device is prevented from being too high under the influence of the environment temperature whilethe normal operation of the power device is ensured, so that the temperature rise value of the power device is reduced, the service life of the power device can be prolonged, and the operation risk of the electrical equipment is reduced.

Description

technical field [0001] The present invention relates to the field of drive control, in particular to an operation control method of electrical equipment, an operation control device of electrical equipment, an external air conditioner and a computer-readable storage medium. Background technique [0002] In the related art, the plug-in vehicle air conditioner uses a low-voltage battery (12V-48V) as a power source, and outputs a high voltage through a connected boost circuit (ie, a drive control circuit) to meet the operating requirements of the air conditioner. The boost circuit will use switching power devices. If the long-term temperature is too high, the aging of the device will be accelerated and the service life will be shortened. What's more, if the heat generation of the device exceeds the limit value, the device will burn out and the entire product will be paralyzed. Contents of the invention [0003] The present invention aims to solve at least one of the technical...
