Embodiment

[0034] Such as figure 1 As shown, an automatic slicing method for fuel cell stack polarization curve test data is used to slice and divide the test data according to the value of the loading current, and the test data of a continuous time period under each value of the loading current is divided into A slice, the method includes the following steps:

[0035] (1) Widely locate the test data for all loading current values: divide the test data with the same loading current value into a wide positioning data segment;

[0036] (2) Accurate positioning of each wide positioning data segment: divide the data belonging to a continuous time period in each wide positioning data segment into a slice, and then obtain the test data slice of the continuous time period under the determined loading current value .

[0037] Before step (1), it also includes: determining the loading type according to the change of the loading current value:

[0038] Monotonic loading: The loading current val...

Abstract

The invention relates to an automatic slicing method for fuel cell stack polarization curve test data. The method is used for slicing and dividing test data according to loading current values. Test data of a continuous time period under each loading current value is defined as a slice. The method comprises the steps of: (1) performing generalized positioning on the test data for all the loading current values, and defining test data with the same loading current value as a generalized positioning data fragment; (2) performing accurate positioning on each generalized positioning data fragment,defining data belonging to a continuous time period in each generalized positioning data fragment as a slice, and further obtaining test data slices of continuous time periods under determined loading current values. Compared with the prior art, the method has the advantages of high slicing efficiency and accurate and reliable results.

Description

technical field [0001] The invention relates to an automatic slicing method for the test data of the polarization curve of a fuel cell stack, in particular to an automatic slicing method for the test data of the polarization curve of the fuel cell stack. Background technique [0002] Fuel cell stack polarization curve test is a relatively common fuel cell stack test type. As the test progresses, the current value of the stack is changed (also known as the single variable test type), and the current changes include the following types: first Lift after drop, drop after lift, drop only, and increase only. Considering the complexity and multilateralism of the test data, the current processing of fuel cell stack polarization curve data in the market is still at the level of manually distinguishing the lifting and lowering loads and then manually slicing each gear current. Contents of the invention [0003] The object of the present invention is to provide an automatic slicing...
