In a significant step towards improving the safety and efficiency of electric vehicle (EV) charging infrastructure, a current transducer from Danisense has been selected for a groundbreaking research project at Graz University of Technology (TU Graz). The ProSafE² project, focused on the Protection, Safety, and Efficiency of Electric Vehicle Charging Stations, is developing periodic verification methods to ensure DC charging stations remain safe and reliable throughout their operating lifespans.
Over the past two and a half years, the project team at TU Graz has designed a ‘mobile charging station testing device demonstrator’ that can be connected to DC charging stations for detailed safety and performance analysis. A critical part of this device is Danisense’s DS600ID current transducer, which delivers the precise and reliable current measurements necessary for the project’s rigorous testing process.
Why Accuracy Matters
The DS600ID transducer is integrated into the DC circuit of the demonstrator to measure the high currents flowing between the testing device and the DC charging station. Ensuring accuracy is paramount, as even minor errors in current measurement can significantly impact calculations related to energy efficiency.
“For such an energy efficiency measurement, you need to have highly accurate current measurements to reduce the impact of the error in the calculation,” said Loic Moreau, EMEA Sales & Marketing Director at Danisense.
Reliable and Precise Measurement
The DS600ID transducer, known for its high accuracy and reliability, was specifically recommended for the project by a colleague from the Austrian Federal Office of Metrology and Surveying. The TU Graz team quickly recognized its potential for the research.
Daniel Herbst, Project Assistant at the Institute of Electrical Power Systems at TU Graz, explained the significance of the component:
“A crucial component for the ‘mobile charging station testing device demonstrator’ we developed to connect to the DC charging station for analysis is the DS600ID current transducer from Danisense. Given the need to measure high currents with utmost reliability and accuracy in our analysis, it was essential to select a precise and high-quality measuring device. The DS600ID component, which was sponsored for our project by Danisense, perfectly meets our requirements, and we are very satisfied with the highly accurate results it provides.”
Ensuring EV Charging Safety and Efficiency
The ProSafE² project plays a critical role in shaping the future of EV charging infrastructure by setting a solid foundation for recurring safety verification. Findings from the research are also being used to update the OVE guideline R 30, an important standard for the safety and testing of EV charging stations.
By leveraging Danisense’s DS600ID transducer, the team at TU Graz ensures that their testing procedures meet the highest standards of accuracy and efficiency, contributing to safer and more reliable charging stations for electric vehicles.
