电动汽车动力电池组电磁干扰研究
Research on electromagnetic interference of electric vehicles power battery
摘要
Abstract
In order to study and restrain the electromagnetic interference caused by the lithium battery in the case of transient current,a distributed capacitance model between power lithium battery pack and chassis was built based on analyzing the structures and equivalent circuit model of lithium batteries.Research platform for interference of electric vehicle batteries was built to extract and analyze the electromagnetic interference generated by the power battery itself as well as the impacts on other electrical circuits in the condition of different current and different change frequency.The results prove that the electromagnetic interference exceeds the national standard requirements for vehicle parts.The inhibition of the circuit on the battery side of the interference plays an obvious inhibitory effect.关键词
