Improving EV Charging Reliability: Addressing Premature Terminations and Enhancing Interoperability Through Rigorous Testing and Certification Programs in Germany

The speaker discusses the challenges and solutions related to electric vehicle (EV) charging infrastructure, focusing on ensuring reliable EV charging sessions. They lament common issues faced by EV drivers, such as non-functional chargers or failed charging processes. The Leitstelle dashboard for Germany reveals significant data: out of roughly 4 million monthly charging sessions, about 8% are prematurely terminated within four minutes. The talk emphasizes multiple reasons behind these failures—issues in communication between the charger and vehicle, poor current regulation by chargers, or malfunctioning battery management systems in vehicles. This highlights a broader challenge due to many involved standards and interfaces among various components like connectors, cables, grid interaction, etc. To address interoperability issues effectively across this ecosystem involving numerous stakeholders (charge point operators, EV makers), CharIN offers conformance testing rather than standard certification. Their specifications aim at enhancing interoperability through coordinated efforts from industry-wide working groups. Validated test systems ensure consistent results across different setups while assessing tester competence ensures robust evaluations leading towards high-level compatibility and reliability in EV charging experiences.

Talk of session: Interoperability Through Conformance Testing

This interactive session looks at the crucial role of common standards for the development, introduction and scaling of the e-mobility ecosystem. Universal interoperability of electric vehicles, electric charging infrastructure and associated digital services need common standards based on rigid conformance testing and certification. Agreeing on common standards for physical, electric and electronic interfaces is in everyone's interest and will promote efficient product development and series production. Recognized certifications will create a market-pull and commercial incentive for common standards.
