Design of a Data Analysis Software about On-board EV Charger Test

摘要

Compared with conventional switching power supply, EV on-board charger has more performance indicators and wider output range so the test is more complex. It need set various conditions to test charger electrical performance and the test will generate large volume of data. Although the precision and function of data acquisition equipment have increased dramatically, but the equipment can't directly determine the performance of a charger. Analysis software of the on-board EV charger testing data is developed based on the on-board EV charger testing hardware platform. The real-time database is used in the software for data management and the algorithms are used for analyzing the test data. The user can choose automatic mode or manual mode to achieve the analysis. The software can comprehensively analyze large amounts of test data, so that the test result is more reliable and accurate. Development of the software provides a way for realizing rapid automatic test to on-board charger.
