LabVIEW based data management design for EV Bi-directional charger test system implementation

Electric Vehicle (EV) bi-directional charger as an important part of the industrial chain for EV can realize two-way power conversion and interaction between EV power battery and power grid. In this paper, a scientific integrated approach to data management in the process of implementing test system for EV bi-directional charger is presented. Combined with the file system and database technology in the LabVIEW environment, this data management mode has centralized and unified process large numbers of test data and system information. Moreover, it can provide data management support for test report and results analysis. By performing the application for test system operation, it has indicated that data management platform will be beneficial to integrate test resources, improve resource utilization, expand the freedom of managing test data, and efficient to reflect the performance of EV bi-directional charger.
