Abstract

The invention provides an electric vehicle air conditioner fault detection method and device, a storage medium and a controller, and the method comprises the steps: detecting whether the operation of an air conditioner is normal or not and / or whether a target component of an air conditioner controller is normal or not after the electric vehicle is powered on and the air conditioner is started; and if it is detected that the operation of the air conditioner is abnormal and / or the target component of the air conditioner controller is abnormal, sending air conditioner fault prompt information through a monitoring diagnosis platform. According to the scheme provided by the invention, offline maintenance can be conveniently notified by detecting the air conditioner controller and locking the fault in time.

Description

technical field [0001] The invention relates to the field of control, in particular to a method, device, storage medium and controller for electric vehicle air conditioner fault detection. Background technique [0002] A pure electric bus is a car that uses a single battery as the power source for energy storage. It uses the battery as the power source for energy storage, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. When the air conditioner of the electric bus is running, the internal The controller plays the role of control and inverter, drives compressors, fans and other loads, and at the same time adjusts the flow direction of the four-way valve and whether to add PTC. Pure electric vehicle air conditioners include cooling-only, heat pump, heat pump + PTC models. When the car is driving in a complex and unpredictable external environment, the requirements for the air conditioner controller are also parti...
