Equipment Testing

Compared with common switching power supply, EV charger has more functional requirements, more severe demands on electrical performance, and wider range of output voltage and current value, what will make the test more complex. Variety of conditions will be set to test the electrical performance of the charger completely, and a large amount of test data will be generated. This article describes the data management platform of EV charging equipment test, which uses real-time database to manage the data. It also detailed introduce data collection and storage, data analysis and report generation and database design of the test platform. The test results show that this system can manage the test data safely, quickly and reliably, providing a convenient and fast way to achieve rapid automated charger test.

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 cant 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.

Electrical Apparatus

Low voltage electrical apparatus is the electrical appliances which play the role of on-off, control or protection in the circuit of AC voltage to the 1200V, DC voltage to1500V. The function of it will have a direct impact on the safe and reliable operation of the power system and industrial control system. It is needed to carry out an accurate test on the each function of them before they leave the factory. In order to ensure the accurate of the test data, it is worth studying on how to build a test data management system for low voltage electrical apparatus. Through LabVIEW establish a connection to the Access database technology. An independent data management system is developed.
