Embodiment Construction

[0033] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but 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 continuously reduce the charge capacity of the battery until it fails to start, which greatly shortens the service life of the battery. In order to reduce 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 replenish the battery of the vehicle in use.

Abstract

The invention provides a control method, device and vehicle air conditioning system for a vehicle air conditioner. The method includes: obtaining the charging times of the battery after the engine is turned off and the voltage of the battery; determining the voltage threshold of the battery allowing undervoltage operation according to the charging times; The comparison result between the voltage and the voltage threshold controls the running state of the vehicle air conditioner or the charging state of the battery. The embodiment of the present invention can control the storage battery to avoid running in a serious undervoltage state, and charge the storage battery in time to prolong the service life of the storage battery.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method and device of 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. Taking long-distance trucks as an example, they are the main force in the transportation industry. In order to improve the driving comfort in hot weather, most of the parking air conditioners are additionally installed on the basis of the original air conditioners. Battery powered. During driving, the original vehicle air conditioner is driven by the engine for cooling; during parking, the cost of idling the original vehicle air conditioner is relatively high, and the battery is used to drive the parking air conditioner for cooling. [0003] When using the battery to drive the parking air conditioner, the existing con...
