Embodiment Construction
[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] According to an embodiment of the present invention, an air conditioner control method is provided, such as figure 1 A schematic flow diagram of an embodiment of the method of the present invention is shown. The air conditioner has a power supply control circuit. The power supply control circuit includes: a power supply switch (such as the vehicle relay K...

The invention discloses an air conditioner control method and device, an air conditioner, a storage medium and a processor. The method comprises the steps that under the condition that the air conditioner is powered on and pre-charged, a power supply switch is controlled to be closed, and an air conditioner pre-charging switch is controlled to be closed; under the condition that the stability degree of the capacitor voltage of the air conditioner reaches the set stability degree, a main switch of the air conditioner is controlled to be switched on; the bus voltage of the air conditioner is sampled; according to the bus voltage obtained through sampling, whether voltage drop occurs to a power supply of the air conditioner or not is determined; and if the voltage of the power supply of the air conditioner drops, a set unit protection mechanism is executed. According to the scheme, the air conditioner can be prevented from being damaged by large current generated when the whole vehicle is quickly powered off and on by adding a voltage drop protection mechanism and controlling mistaken protection when the voltage fluctuates.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner control method, device, air conditioner, storage medium and processor, in particular to a control method, device, air conditioner, storage medium and processor for preventing voltage anomalies. Background technique [0002] After the electric vehicle air conditioner is powered on, it is necessary to close the air conditioner pre-charging relay K 空调预充 Precharge the air conditioner capacitor, close the air conditioner main relay K after normal charging is completed 空调主 , the air conditioner can operate normally. When the car key is manually turned quickly, the vehicle relay K 整车 It will be disconnected and closed quickly, and the moment the vehicle is quickly powered on, there will be a large current that is enough to damage the device. It can be seen that the air conditioner for electric vehicles has a voltage drop when it is powered on q...
