A current research project at Graz University of Technology is analyzing periodic verification and safety of direct current (dc) electric vehicle (EV) charging stations.
As part of the ProSafE² project (Protection, Safety, and Efficiency of Electric Vehicle Charging Stations), researchers have spent two-and-a-half years developing a test procedure for recurring safety assessments of dc charging stations to ensure reliability throughout their operating lifespan. Insights gained from the project also contribute to OVE R 30 guideline updates.
To support the project, a DS600ID current transducer from Danisense has been integrated into the dc circuit of a mobile charging station testing device demonstrator, which connects to the dc charging station.
The current transducer enables precise measurement of currents flowing between the charging station and the demonstrator — critical for evaluating safety and energy efficiency. Accurate current measurements play a key role in minimizing calculation errors during energy efficiency assessments, a project’s core focus.
The DS600ID current transducer was selected based on its ability to deliver highly accurate and reliable high-current measurements, ensuring the integrity of the testing process. Sponsored by Danisense, the component has proven to meet the project’s stringent requirements, providing highly precise results necessary for effective analysis.
The high-precision dc current transducer (DCCT) measuring up to 1000-A currents and continuously measuring 900-A currents with a linearity error less than 1 ppm. Based on the ultra stable Danisense closed loop flux gate technology, the DS600ID has very low offset and ultra low drift. It provides high resolution for precise monitoring, reliable and consistent performance, and a rugged design for durability.
This research underscores the importance of accurate periodic verification for dc charging stations, supporting long-term safety and energy performance as electric vehicle infrastructure continues to expand.
