Overview
IEC TS 63379:2026 specifies requirements and guidelines for vehicle connectors, vehicle inlets, and cable assemblies designed for megawatt DC charging systems. This technical specification applies to accessories with standardized pin and contact-tube configurations, used in electric vehicle (EV) conductive charging infrastructure. The standard covers devices operating at rated voltages up to 1,500 V DC and currents up to 3,000 A, incorporating thermal management measures such as thermal sensing or a combination of thermal sensing and thermal transport.
The specification supports the safe, reliable, and efficient transfer of high-power DC electricity, enabling rapid charging for heavy-duty vehicles, commercial fleets, and other applications requiring megawatt-level charging rates.
