In existing trucks, the truck is configured with two sets of air conditioning systems. Wherein, a set of air conditioning system comprises a vehicle-mounted integral air conditioner which is driven by an engine so as to adjust the environmental temperature in a cab in the driving process; the other set of air conditioning system comprises a parking air conditioner, wherein the parking air conditioner is powered by a vehicle battery on the truck, and when the truck is in a parking state, the engine is in an idling state or a flameout state, and at the moment, the parking air conditioner is used for adjusting the ambient temperature in the cab. The method for warning the life of the vehicle battery according to the present invention will be described with reference to a parking air conditioner.
Vehicle batteries on trucks are used to power electrical equipment such as parking air conditioners, ignition devices, lighting devices, etc. During the use process of the parking air conditioner, the output voltage of the vehicle battery is detected in real time, timing is started when the output voltage of the vehicle battery is at a first voltage value, the timing is ended along with the continuous power supply of the vehicle battery when the output voltage of the vehicle battery is reduced to a second voltage value, a first time length used for the output voltage of the vehicle battery to be reduced from the first voltage value to the second voltage value is obtained, and then the first time length is compared with a reference time length.
