摘要
Abstract
With the proposal of VEG mode of electric vehicles, the large power off-board charge has been widely used owing to its safe and fast charging features.The 300 kW verification system is figured out to cover full range calibration of large power vehicle charger in real-load.DC comparators which provide reliable test data for large current measurement through adopting a variety of shielding techniques to maintain the accuracy still at 10 ppm level under strong electromagnetic interference in centralized station.LabVIEW is applied for software design and data processing.The verification system provides the foundation for energy metering traceability of off-board charger.Finally, through the contrast data and statistical analysis, the proposal that energy meteorology unit should be placed in charger DC side is put forward to achieve a fair settlement.关键词
