Abstract
This paper presents the main findings from an ongoing experimental research, which is part of an exploratory activity at the European Commission's Joint Research Centre, on the aspect of radiated and conducted electromagnetic interference and RF disturbances from production electric vehicles (EVs) and their recharging units (EVSEs). The aim is to share and disseminate novel findings about the EMI fingerprint of EVs and EVSEs under realistic setups and operating conditions, beyond the legislative test methods prescribed on the automotive EMC standards, in order to exploit the magnitude of the interference that these systems can generate to the environment and the wireless spectrum. Representative laboratory results in this paper, among numerous other setups realized during this research, were extracted from actual measurements within a validated automotive EMC SAC for 5 chargers, portable (2.5kW) and stationary (up to 60kW) and 8 electric vehicle samples from the market.
