Challenges and related Solutions for Periodic Verification of DC Electric Vehicle Charging Stations

For the periodic verification of DC electric vehicle charging stations (EVCSs) currently no standardised verification and test procedures or associating methods and protocols have been established. This belongs to the incomplete standardisation work as well as the ongoing developments of EVCS. In the course of this paper, first important approaches for possible procedures for the periodic verification of DC-EVCSs, which are already installed in the field, are presented. On the one hand, appropriately applicable sequences from existing AC test routines will be used, and on the other hand, new test procedures required in addition for DC charging stations are presented. Furthermore, a mobile high performance test device demonstrator including its functional scope is shown. Still existing questions and challenges with regard to the mentioned topic round off the article.
