摘　　要：针对市场上充电桩计量精度低,校准平台分析误差较大的问题,文中在传统计量系统的基础上进行改进,增加其计量精度,同时降低校准平台的分析误差。通过设计V2G拓扑电路实现充电桩与计量装置的连线互通,保证计量装置在极短时间内接收信号。利用超越安全阈值(Threshold Beyond Safety,TBS)算法模型对计量数据进行校准分析,通过推算极限阈值判断校准误差。试验表明,该研究充电桩运行功率为139.5W,计量精度为96.1%,校准平台分析误差为0.96%。Based on the problems of the low measurement accuracy of the charging piles on the market and the large analysis error of the calibration platform,this paper improves on the traditional measurement system to increase its measurement accuracy and reduce the analysis error of the calibration platform.Through the design of the V2G topology circuit,the connection between the charging pile and the metering device is realized to ensure that the metering device receives signals in a very short time.The Threshold Beyond Safety TBS algorithm model is used to calibrate and analyze the measurement data,and the calibration error is judged by estimating the limit threshold.The test shows that the operating power of the charging pile in this study is 139.5W,the measurement accuracy is 96.1%,and the analysis error of the calibration platform is 0.96%.
