Green NCAP CharIN EV Charging Compatibility Partnership Improves Interoperability Transparency

Electric vehicle charging compatibility is becoming a critical factor in the global transition to electrified mobility. In this context, Green NCAP has signed a Memorandum of Understanding with CharIN to strengthen transparency and technical validation of charging interoperability. The partnership focuses on integrating conformance testing into vehicle assessments so that EV charging systems from different manufacturers and networks can operate together more reliably and predictably for drivers.

Integration of CharIN Conformance Testing into Vehicle Assessments

Under the agreement, Green NCAP will incorporate CharIN’s conformance testing procedures into its electric vehicle evaluation framework. These tests verify whether vehicles and charging infrastructure comply with established industry protocols governing EV charging communication and functionality. By adding this layer of verification, the assessment program will examine how well electric vehicles interact with electric vehicle supply equipment across different brands and charging networks, providing deeper insights into real-world interoperability performance.

Improving Transparency for Drivers, Fleets, and Policymakers

Conformance testing ensures that EVs and chargers follow common technical standards, enabling vehicles to connect and charge smoothly across multiple infrastructure providers. As part of the collaboration, Green NCAP may reference the CharIN Label within its Driving Experience evaluation when applicable, while testing may be conducted directly under CharIN procedures or by authorized partners. The initiative ultimately aims to deliver clearer information on charging compatibility and performance, helping consumers, fleet operators, and policymakers better understand the practical usability of electric vehicle charging ecosystems.
