The invention discloses an air conditioner control method and system for rail vehicles with intermittent power supply. The air conditioner is controlled to be in a pre-working mode, a normal working mode and an energy-saving working mode under different circumstances. The target temperature maximizes the storage of energy during charging to maintain the comfort of the vehicle during subsequent operation, and at the same time reduces the energy consumption of the vehicle's air conditioner when the vehicle is not charging, and prolongs the continuous supply of energy storage power to traction and braking. The ability of the key system to provide the necessary power supply; the air conditioner is in different energy-saving working modes according to the available electric energy and different setting thresholds, which further ensures the necessary power supply capacity of the vehicle and at the same time ensures the comfort of passengers.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning control for vehicles, and in particular relates to an air-conditioning control method, system and vehicle for rail vehicles with intermittent power supply. Background technique [0002] Traditional rail vehicle air conditioners are powered by AC380V power, which is obtained by inverting DC high-voltage power through static converters. Since traditional rail vehicles are powered by the third rail or catenary, as long as the high-voltage power supply is available, the air conditioner can always work at the rated operating point, and its energy consumption is only related to the external environment (temperature and humidity) and the passenger capacity in the vehicle. Due to environmental and cost considerations, intermittently powered rail vehicles are gaining more and more attention. Intermittent power supply rail vehicles use supercapacitors or batteries to drive vehicles to start in a f...
