Latest development of the national and international EMC-standards for electric vehicles and their charging infrastructure

Abstract

For a long term success of electric mobility, it's definitely necessary to provide safe charging infrastructures in addition to marketable vehicles. Since safety and functionality requirements on every electric mobility product are extremely high, the interoperability between charging infrastructure and vehicle, as well as the interaction of both systems under every possible environmental condition and parameter variations are significant. In addition to climatic and mechanical influences, electromagnetic influence, e.g. broadcast transmitter, mobile phones, the disturbances caused by the systems themselves and the sensibility to each other, belongs also to environmental requirement. Focusing on the Electromagnetic Compatibility (EMC) of the charging infrastructure of these vehicles, the normative standards have to be adapted to these new circumstances. In this paper, several critical issues, especially the controversial discussed aspects regarding EMC in the draft version of IEC 61851-21-2, which is an EMC standard for conductive charging infrastructure, are demonstrated according to the diverse charging modes and the special interfaces to energy supply networks.
