Abstract

The invention relates to the technical field of new energy vehicles, in particular to a control system and method for an air conditioner of an electric vehicle. The system comprises a remote control module mounted in a mobile device, a background server and the electric vehicle and is characterized in that the electric vehicle comprises a vehicle-mounted intelligent terminal, an air conditioner related component control system, an awakening relay and a storage battery; the remote control module communicates with the background server through a mobile network, the background server communicates with the vehicle-mounted intelligent terminal through the mobile network, and the vehicle-mounted intelligent terminal is connected to a CAN network of the electric vehicle; two contact points of the awakening relay are connected with the storage battery and the air conditioner related component control system respectively, and a control end of the awakening relay is electrically connected with the vehicle-mounted intelligent terminal; the air conditioner related component control system comprises an air conditioner control module, a complete vehicle controller, a battery management module, a DCAC inverter and a DCDC convertor.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric vehicle air conditioning control system and control method. Background technique [0002] Mid-to-high-end models of traditional gasoline vehicles can remotely start the engine through the remote control key, and the air conditioner can be turned on only when the air conditioner system was not turned off in the last driving cycle. And can't realize carrying out temperature control to air-conditioning, only carry out cabin temperature automatic regulation when being equipped with automatic air-conditioning system in gasoline vehicle. There have also been some remote air-conditioning controls through post-modification in China, which have a high risk of modification and require additional equipment to realize signal transmission. [0003] The remote air-conditioning control system for new energy vehicles such as pure electric vehicles can only achieve single...
