Abstract

The invention provides a hydrogen fuel cell system performance detection method and device, equipment and a medium. After the vehicle enters a performance detection mode, monitoring rated power density, starting time, first response time of rated power of the battery system from 10% to 90%, second response time of rated power of the battery system from 0% to 50%, maximum power density and hydrogen utilization rate, and calculating according to the indexes to obtain the performance percentage of the battery system, and pushing the performance percentage through an instrument panel or a vehicle-mounted terminal of the vehicle. The operation that a user needs to carry out detection in a laboratory is avoided, the operation steps are effectively reduced, the accuracy of the detection result is improved, and the time cost and the labor cost are reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a detection method, device, equipment and medium for the performance of a hydrogen fuel cell system. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy. It emits very little harmful gas and has a long service life. With the development of fuel cell technology, more and more vehicles use hydrogen. For fuel cells, it is very important for users to discover the performance degradation of the battery system in time, which can effectively reduce the losses of users and reduce the risk of using vehicles. [0003] In the prior art, the detection of the performance of the vehicle-mounted hydrogen fuel cell system is to put the hydrogen fuel cell in the laboratory before the vehicle is assembled, and the laboratory staff manually test the steady-state performance, starting performance and dynamic perfo...
