Abstract

The invention discloses a fuel cell thermal management test system and a test method. The test system comprises a liquid storage tank for storing cooling liquid; an electric pile simulator with a liquid inlet, a liquid outlet, a first return port and a second return port; a thermostat having an inlet, a first outlet, and a second outlet; a booster pump, wherein the inlet of the booster pump is communicated with the liquid outlet, and the booster pump sucks the cooling liquid out and conveys the cooling liquid to the inlet of the thermostat after boosting; a heater in communication with the first outlet; and a radiator in communication with the second outlet. The liquid outlet, the booster pump, the thermostat, the heater and the first return port form a heating circulation module; the liquid outlet, the booster pump, the thermostat, the radiator and the second return port form a radiation circulation module. A flowmeter, a temperature sensor and a pressure sensor are arranged on each of the heating circulation module and the radiation circulation module. The test system can simulate and analyze the functions of radiation circulation and heating circulation, and the efficiency and reliability of the functional analysis of the fuel cell thermal management subsystem are improved.

Description

technical field [0001] The invention relates to the field of performance testing of vehicle components, in particular to a fuel cell thermal management testing system and testing method. Background technique [0002] Temperature is one of the important factors affecting the performance of fuel cells. In addition to generating electrical energy during the working process of fuel cells, about half of the energy is output in the form of heat. Therefore, excess heat must be discharged to maintain the stability of the system's operating temperature. The internal temperature environment of the fuel cell stack has a great influence on the reliability, life and performance of the stack, so it is particularly important to maintain the temperature in the stack within a certain range. The liquid cooling technology in the stack has been widely used due to its high heat transfer efficiency. Among them, the liquid cooling system often needs to use an external system to dissipate heat fro...
