CONCEPTUAL MODEL FOR THE HARMONIZATION OF ELECTRIC VEHICLE CHARGING INFRASTRUCTURE STANDARDS IN UZBEKISTAN BASED ON INTERNATIONAL REQUIREMENTS

The rapid development of electromobility in Uzbekistan requires a coordinated system of charging infrastructure standards ensuring interoperability, safety, and metrological reliability. This study proposes a harmonization model based on the comparison of international IEC/ISO/EN and regional (including GB/T) standards with national documents (UzTR, O‘z DSt, GOST). The methodology applies a four-criteria assessment (technical equivalence, functional compatibility, version relevance, regulatory applicability) with A/B/C categorization and a visual EVI Harmonization Framework.
