Abstract

This paper is devoted to the infrastructure issues arising from the ultrafast charging of electric vehicles in the timeframe of ~5 minutes. To mitigate variances and peaks caused by high energy transfer rate and pulse-like load, an ultrafast charging station must be partially decoupled from the utility grid by the usage of intermediate energy buffers. The perspective charging station load and its management by intermediate buffering are analysed and discussed with a tentative design proposal.
