Abstract:

This paper includes the first results that analyze the influence of the spectral shape of the conducted emissions generated by Electric Vehicle Charging Processes (EVCPs) on Narrowband Power Line Communications (NB-PLC) according to PRIME v1.4 standard. The performance evaluation is carried out by means of Frame Error Rate (FER) vs Signal to Noise Ratio (SNR) curves obtained by reproducing, under laboratory conditions, real emissions corresponding to seven commercial EV models with different charging currents. Prior to the performance evaluation, a characterization of the Non-Intentional Emissions (NIEs) in the frequency domain is presented according to CISPR 16-1-1. In the 42-89 kHz frequency band (channel 1 defined in PRIME v1.4), this characterization shows high-amplitude tonal or narrowband emissions with respect to the noise floor. In channels 3-8 (151-471 kHz), in turn, multiple low-amplitude emissions are observed for all the EVCPs under study. The FER-SNR curves show that the spectral pattern of the emissions in channels 3-8 is more critical for communications than in channel 1 due to their flatness. Further studies are in progress to evaluate the influence of more aspects of the NIEs (actual amplitude, spectral distribution and time variability) on PRIME v1.4 and G3-PLC up to 500 kHz.
