Research on Data Efficiency of Fuel Cell Vehicles Based on Demonstration Platform

With the number of fuel cell vehicles in operation exceeding 10000, the data quality issue regarding the national hydrogen energy and fuel cell vehicle demonstration evaluation platform has become even more challenging. In order to accurately evaluate the quality of data uploaded by car companies and improve their efficiency, based on the provisions of GB/T 32960.3-2016 on the effective range of data, a data efficiency calculation method is established. Furthermore, a data cleaning algorithm is proposed to improve the quality of data diagnosis through data missing handling and data anomaly diagnosis. By comparing the efficiency of the data before and after the data cleaning algorithm, the effectiveness and scientificity of the algorithm can be demonstrated.
