Abstract

The invention provides a control method and device for a fuel cell thermal management system, and the method comprises the steps: carrying out the power-on self-test of the fuel cell thermal management system, and obtaining a power-on self-test result; when the power-on self-test result is no fault, receiving a starting instruction, controlling the fuel cell thermal management system to start according to the starting instruction, and obtaining the temperature of a galvanic pile cooling liquid outlet of the galvanic pile; when the temperature of the electric pile cooling liquid outlet is greater than or equal to the threshold temperature, performing large and small circulation switching on the fuel cell thermal management system; obtaining a heat dissipation environment change state, and adjusting a state parameter of the fuel cell thermal management system based on the heat dissipation environment change state and the required cooling liquid outlet temperature; and receiving a shutdown instruction, and controlling the fuel cell thermal management system to shut down according to the shutdown instruction. According to the invention, the control comprehensiveness of the thermal management system of the fuel cell is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cell thermal management systems, in particular to a control method and device for a fuel cell thermal management system. Background technique [0002] New energy vehicles represented by fuel cell vehicles have the advantages of energy saving and environmental protection. They have developed rapidly in recent years and have good application prospects. Especially in the field of commercial vehicles, fuel cell vehicles have a longer driving range than pure electric vehicles. However, compared with traditional internal combustion engine vehicles, fuel cell vehicles face greater challenges in thermal management. [0003] In the prior art, the fuel cell thermal management system basically only describes a certain part of the thermal management process, such as a single process such as low-temperature startup, large and small cycle switching, etc., without considering the overall control scheme of the fuel...
