Problems solved by technology

[0002] When the car air conditioner is turned on, it will detect the power stored in the battery. Usually, the detection method is to intuitively judge whether the battery voltage is sufficient. Low voltage means that the battery power is low. Therefore, it is necessary to change the frequency of the air conditioner or turn off the power consumption of the air conditioner. The usable life of the old battery is completely different, so the aging degree of the battery cannot be effectively distinguished. If the same power supply control method is used for the old and new batteries, the battery loss will be increased, the battery life will be reduced, and the user experience will be reduced.

Abstract

The invention provides a driving control method and device, an air conditioner, a vehicle and a storage medium. Wherein, the drive control method includes: obtaining the output voltage of the power supply, and determining the rate of change of the output voltage with time; and adjusting the operating frequency of the load according to the rate of change. Adjusting the operating frequency of the load according to the rate of change of the output voltage of the power supply can match the operating state of the load with the power supply state of the power supply, avoiding the reduction of load efficiency and excessive power supply caused by the mismatch between the working state of the load and the power supply state of the power supply. In case of loss, on the one hand, it ensures the operating efficiency of the load and improves the effect of load operation; on the other hand, it reduces the extra consumption of the power supply and improves the life of the power supply.

Description

technical field [0001] The present invention relates to the technical field of vehicle-mounted air conditioners, in particular, to a drive control method, a drive control device, an air conditioner, a vehicle, and a computer-readable storage medium. Background technique [0002] When the car air conditioner is turned on, it will detect the power stored in the battery. Usually, the detection method is to intuitively judge whether the battery voltage is sufficient. Low voltage means that the battery power is low. Therefore, it is necessary to change the frequency of the air conditioner or turn off the power consumption of the air conditioner. It is completely different from the usable life of the old battery, so it cannot effectively distinguish the aging degree of the battery. If the same power supply control method is used for the new and old batteries, the battery loss will be increased, the battery life will be reduced, and the user experience will be reduced.
