Embodiment 1

[0039] The experimental object is a fuel cell divided into 64 partitions. In an experiment of a partitioned fuel cell with a duration of 4 hours and a data acquisition frequency of 1 time per second, hundreds of thousands of experimental raw data were generated. At the same time, the fuel cell test platform is taking the whole fuel cell as the object Collect data such as average current density, average voltage, inlet and outlet pressure, flow rate, etc.

[0040] In this embodiment, the raw data of the fuel cell experiment is the experimental data from the test platform and the fuel cell as a whole, and the data is processed in Excel. Such as figure 1 As shown, a VBA module-based partitioned fuel cell experimental data processing method provided by the embodiment of the present invention is specifically:

[0041] In step s1, a VBA data processing module is established, and the established VBA data processing module includes a data import module, a data formatting module, an ...

Embodiment 2

[0052] In this embodiment, the raw data of the fuel cell experiment is the experimental data measured based on the fuel cell on-line partition test technology with each partition of the fuel cell as the object, and draws the selected points for operation under the vehicle operating conditions.

[0053] Simulated vehicle working conditions usually include test conditions such as start-stop / open circuit, idle speed, constant load, variable load and acceleration. Combining these test conditions according to a certain ratio forms a fuel cell durability evaluation method that simulates vehicle conditions. This method not only combines the actual operation of the fuel cell, but also investigates the fuel cell as a whole, so that the performance of the fuel cell can be analyzed comprehensively.

[0054] The simulated driving conditions used in the experiment are self-made working conditions according to the actual driving conditions of the vehicle, including open-road conditions, idl...

Abstract

The invention relates to a partition fuel cell experimental data processing method and system based on a VBA module. The method comprises the steps that a VBA data processing module is established; the VBA data processing module is called to import original data of a fuel cell experiment; the VBA data processing module is called to conduct formatting processing on the imported data; the VBA data processing module is called to draw a corresponding image; the VBA data processing module is called to conduct formatting processing on the drawn image. Compared with the prior art, the partition fuel cell experimental data processing method and system based on the VBA module have the advantages of being fast, automatic, capable of greatly improving the data process efficiency and the like.

Description

technical field [0001] The invention relates to a method and system for processing experimental data of partitioned fuel cells based on a VBA module. Background technique [0002] For nearly a century, human society is experiencing rapid development. With the continuous growth of energy consumption around the world, traditional energy sources have been overwhelmed and are facing a crisis of depletion. At present, the energy supply in most countries is insufficient, coupled with the environmental pollution caused by the exhaust emissions of traditional fuel vehicles, the development of new energy vehicles has become the consensus of all countries in the world. Among them, fuel cell vehicles (Fuel Cell Vehicle, FCV) have won the policy support of governments of various countries and extensive media attention due to their high power density, environmental friendliness, and rapid start-up. R&D strategic priorities for automakers. [0003] There are still some technical bottlen...
