Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] If the battery is in a state of power loss for a long time, the plates will slowly vulcanize. This chronic vulcanization will reduce the charge capacity of the battery until the starting is weak, which greatly shortens the service life of the battery. In order to restore the active substances on the battery plate in time, reduce the chronic vulcanization of the plate, increase the charge capacity of the battery, and prolong its service life, it is necessary to regularly recharge the battery in use.

Abstract

The invention provides a control method and a device for a vehicle-mounted air conditioner and a vehicle-mounted air conditioner system. The control method comprises the steps obtaining the charging frequency of a storage battery after an engine is shut down and the voltage of the storage battery; determining a voltage threshold value allowing under-voltage operation of the storage battery according to the charging frequency; and controlling the running state of the vehicle-mounted air conditioner or the charging state of the storage battery according to the comparison result of the voltage and the voltage threshold value. According to the embodiment of the invention, the storage battery can be controlled to be prevented from running in a severe under-voltage state, the storage battery ischarged in time, and the service life of the storage battery is prolonged.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method and device for a vehicle air conditioner and a vehicle air conditioner system. Background technique [0002] With social development and consumption upgrading, consumers have higher and higher requirements for product comfort. Take long-distance trucks as an example, which are the main force in the transportation industry. In order to improve driving comfort in hot weather, most of the original car air conditioners are equipped with additional parking air conditioners. The parking air conditioner is generally provided by the truck. Battery powered. During driving, the original car air conditioner is driven by the engine for cooling; during parking, the cost of driving the original car air conditioner at idling speed is relatively high, and the battery is used to drive the parking air conditioner for cooling. [0003] When the battery is used to...
