Problems solved by technology

[0002] The existing plug-in vehicle air conditioners are powered by batteries and have protection functions for the batteries. The battery voltage can directly reflect the battery power, so most of them use the battery voltage as the basis for protection, but there are certain disadvantages in limiting the frequency of the compressor according to the voltage. , because in different temperature, humidity and pressure environments, the power consumed by the same compressor frequency is not the same, so the consumption of battery power is not the same, so the protection effect will be different in different environments, This may lead to the risk of failure of the above method in some extreme environments and cannot protect the battery

Abstract

The invention provides a control method and a control device of an air conditioner, and the air conditioner. The method comprises the following steps: obtaining the current running frequency of the air conditioner and a first target running frequency corresponding to the current running frequency; determining input current transmitted to the air conditioner by a battery assembly; and adjusting thefirst target running frequency according to the input current and the current running frequency to obtain an adjusted second target running frequency. The control method adjusts the target running frequency of the air conditioner through the current, so the problem that the battery assembly cannot be protected in time due to detection errors during frequency adjustment from the voltage is solved,and the battery assembly can be better protected; and only the current of an input end and the running frequency of the air conditioner are used as limiting conditions, and a detection line for detecting the output voltage or current of the battery assembly does not need to be additionally arranged, so the cost is reduced, and installation and maintenance steps are simplified.
