Plug-in electric air conditioner of automobile

Abstract

The invention provides a plug-in electric air conditioner of an automobile. An air conditioning unit is connected with an air conditioner battery, a vehicle generator and a charger through lines, whole regulation is connected with a controller through lines, the vehicle generator line is connected with the air conditioner battery, another line of the charger is connected onto an automobile battery, and a communication interface is provided. During usage, the controller can regulate the operation of the automobile and power utilization of the air conditioner automatically, the air conditioning unit has priority to use a power supply in the air conditioner battery, when the electric quantity of the air conditioner battery drops to a set limit, the vehicle generator is switched for power supply, when the automobile stops, an external power supply connects the charger to charge the air conditioner battery and the automobile battery as well as the automobile air conditioner, the air conditioner battery can boost charge for the automobile battery, the problem that the electric energy cannot be guaranteed due to the fact that one automobile battery is shared by the existing automobile air conditioner and operation of the automobile is solved effectively, overall power utilization and charging are adjusted orderly, scientifically and reasonably, and the remote regulating operation can be performed through the communication interface.

Description

technical field [0001] The invention relates to an automobile air conditioner and a power distribution system for vehicle operation, in particular to a plug-in electric automobile air conditioner. Background technique [0002] When the car is running and the air conditioner is turned on, the car engine needs to provide power supply. If the car is coasting and parking, the engine will be in an idling state. In this case, if the air conditioner continues to be turned on, the engine idle speed must be increased. This idling condition not only increases the fuel consumption of the vehicle, but also leads to a sharp increase in the harmful pollutants of the engine, especially for heavy-duty vehicles and buses with relatively high horsepower.

Problems solved by technology

[0002] When the car is running and the air conditioner is turned on, the car engine needs to provide power supply. If the car is coasting and parking, the engine will be in an idling state. In this case, if the air conditioner continues to be turned on, the engine idle speed must be increased. This idling condition not only increases the fuel consumption of the vehicle, but also leads to a sharp increase in the harmful pollutants of the engine, especially for heavy-duty vehicles and buses with relatively high horsepower. Especially prominent, in the prior art, there is a proposal to use an external power supply for the air-conditioning unit, but it fails to solve the overall power supply plan, and another proposal proposes energy management for the air-conditioning unit, but it still fails to fully propose the effective power supply. Configuration scheme, in the current automotive field, due to the failure to effectively solve the problem of reasonable control of the simultaneous power supply and power consumption of vehicle air conditioners and vehicle operation, it will have a great impact on the future development and safe operation of vehicles.
