基于离散Fréchet距离的电动汽车电池健康状态诊断方法
EV battery SOH diagnosis method based on discrete Fréchet distance
摘要
Abstract
For EV battery safety andpower performanceduringrunning, this paper combines discrete Fréchet distance methodand identification of battery charge-discharge curveto propose a diagnostic methodof batterySOH based on online test platform. Systemcancontrol directly EV battery tocomplete the full charge-discharge test online by CAN communication module, and get the actual operational status data.EV service full cycle information databasesare established to forecast the diagnosis of healthdegree,which can guide power battery safety assessment and balanced maintenance. By analyzing the cases of test calculation,thecorrectness and accuracy of the method is verified after comparing diagnosisresultand test data of switching off.关键词
