PAUSED-EV-CHARGING

This repository contains the codes and results which is published in the paper titled: "Enhancing smart charging in electric vehicles by addressing paused and delayed charging problems".

The following repository is maintained by Nico Brinkel and Nanda Kishor Panda

Highlights

✅ Many electric vehicle models lack the technical capabilities for effective smart charging, as they cannot handle charging pauses or delays. 🚗 🚙
✅ Technical charging tests reveal that around one-third of tested car models suffer from these charging issues.
✅ Model simulations suggest that eliminating these problems would double the smart charging potential for all applications.
✅ Concrete legal and practical solutions are proposed to address these issues. ⚖️
