The United Nations Economic Commission for Europe has decided to develop a unified global procedure to measure the fast charging capability of electric vehicles and determine how to convey this information to car owners, consumers, and the public.

Currently, original equipment manufacturers typically communicate the maximum charging speed of their electric vehicles. However, the conditions under which each vehicle reaches these values vary greatly, depending on battery technology, cooling systems, and battery management systems, which can lead to significant differences in charging times. Moreover, this information is not widely disclosed, and its measurement methods are not yet unified.

The Economic Commission will establish a unified method to measure the fastest charging power curve of electric vehicles using direct current, ensuring the consistency of measurement conditions and guaranteeing the robustness and repeatability of the tests. At the same time, the organization will also develop a dedicated consumer information package to help consumers easily assess the charging speed of electric vehicles. The organization hopes that this method will become a voluntary standard used by legislators, car manufacturers, charging station operators, and other stakeholders in the field of electric vehicles.

Recently, the Economic Commission has analyzed the electric vehicle charging infrastructure of its member countries, revealing the distribution and accessibility of charging pools, charging stations, and charging points, as well as the gaps that still exist.

This method is expected to be completed by the end of 2025, driven by the UN Economic Commission for Europe's Working Party on the Harmonization of Vehicle Regulations (WP.29), in collaboration with the Joint Pollution and Energy Working Group (GRPE), the Working Party on Transport Trends and Economics (WP.5), and the UNECE Division of Sustainable Energy, focusing on the field of fast smart charging.
