WIPO Patent Application WO/2023/070607
Kind Code:
A1
Abstract:
A vehicle refrigeration control method and apparatus, and a device, a medium and a program product. The method comprises: measuring the temperature of a battery in a target vehicle and the change rate of the temperature in real time; then, determining the refrigeration demand level of the battery according to the temperature and the change rate; when it is detected that both a passenger compartment and the battery of the target vehicle have refrigeration demands at the same time, determining, according to the current refrigeration demand level of the battery, a refrigeration mode that the target vehicle needs to enter; and determining a control instruction of each target control object according to the refrigeration mode, wherein the refrigeration mode comprises: a single-mode stage, which is used for refrigerating the passenger compartment or the battery alone, and a dual-mode stage, which is used for simultaneously refrigerating the passenger compartment and the battery, and the single-mode stage is arranged before the dual-mode stage. The technical problem of how to allocate and control the refrigeration capacity of a new energy vehicle is solved, and while the comfort of a passenger compartment is firstly ensured, the technical effect of meeting the refrigeration demand of a battery by means of flexibly allocating the total refrigeration performance of the vehicle is achieved.
