Connector Compatibility: GB/T 20234 vs IEC 62196 Type 2 / CCS2 China's common GB-standard connector baseline is GB/T 20234 for AC and DC conductive-charging connection devices. GB/T 20234 interfaces are not a drop-in substitute for IEC 62196 Type 2 or CCS2 interfaces.GB/T 20234.1-2023
GB/T 20234.2
GB/T 20234.3-2023		 Where a Vietnam project, fleet, or charging operator specifies IEC connectors, AC chargers normally need IEC 62196-2 Type 2 compatibility and DC chargers may need IEC 62196-3 Configuration FF, commonly called CCS2. Connector selection is a hardware and interoperability decision, not only a label or document change. A proposed citation to a TCVN 14296:2025 series adopting IEC 62196:2022 could not be verified from official-source searches as of 2026-06-13.IEC 62196-2 Type 2 AC accessories
IEC 62196-3 Configuration FF / CCS2 DC couplers
Project or operator connector specification		 Exporters should confirm the connector ecosystem of the Vietnamese customer base and redesign cables, sockets, vehicle connectors, inlet compatibility, pilot signaling, locks, thermal sensing, and markings where IEC Type 2 or CCS2 is specified. Do not rely on the unverified TCVN 14296:2025 citation without an official catalogue record or text.[INFORMATIONAL] GB/T 20234 connector evidence should not be presented as Type 2 or CCS2 evidence. Vietnam projects using IEC connector ecosystems need hardware-level connector confirmation; the proposed TCVN 14296:2025 adoption claim could not be verified.

EMC, RCD, Earthing, and Electrical Safety Evidence China's common GB-standard baseline includes GB/T 18487.1 for conductive charging systems and GB/T 18487.2 for off-board conductive supply equipment EMC. These are not automatic substitutes for Vietnam-facing IEC / TCVN evidence.GB/T 18487.1-2023
GB/T 18487.2		 Vietnam-facing EVSE documentation should include IEC-family EMC and electrical safety evidence suited to the installation. IEC 61851-21-2 addresses EMC for off-board EV charging systems, while IEC 61851-1 is the general EV conductive charging safety baseline used for protection, control, and installation interfaces.IEC 61851-21-2: EMC requirements for off-board electric vehicle charging systems
IEC 61851-1: general requirements
Project-specific RCD, residual DC detection, earthing, surge protection, IP rating, and installation requirements		 Prepare EMC reports, RCD or RDC-DD selection evidence, residual DC protection data, earthing design, surge protection ratings, enclosure ratings, thermal limits, and installation instructions matched to the Vietnamese site and utility design.[INFORMATIONAL] GB/T 18487 safety and EMC files should be remapped to the IEC / TCVN evidence requested for the Vietnamese installation, especially RCD, residual DC, earthing, and EMC details.

China GB/T 18487 Baseline vs Vietnam Route The China GB-standard baseline is GB/T 18487.1-2023, supported by GB/T 20234 connector standards and GB/T 27930 charger-to-vehicle communication. This package is China-specific and should be converted into a Vietnam-facing compliance matrix.GB/T 18487.1-2023
GB/T 20234.1-2023
GB/T 20234.3-2023
GB/T 27930-2023		 Vietnam market entry should start from the applicable Vietnamese standards, utility, operator, and installation route. China GB/T 18487 evidence is relevant technical input, but the Vietnamese route may require IEC / TCVN mapping, IEC connector evidence, local grid documentation, and operator integration evidence.Vietnam TCVN / IEC charging-equipment route
Vietnam utility and operator project requirements
Vietnam site-specific installation approval		 The practical gap is a conversion package: map GB/T clauses to TCVN / IEC clauses, identify connector and communication differences, translate and localize manuals, prepare EVN load and protection data, and confirm whether any Vietnam authority, tender, or operator requires third-party testing.[INFORMATIONAL] GB/T 18487 is the correct China-side baseline, not the final Vietnam answer. Build a Vietnam-specific matrix covering TCVN / IEC, connector, OCPP, EMC / RCD, and EVN site requirements.

EVN Grid Supply and MOIT Charging-Station Rules China GB-standard charger files, GB/T 18487 evidence, and domestic grid-connection records do not replace Vietnamese electricity-supply coordination, metering, tariff, or site energization steps.GB/T 18487.1-2023
China project-specific grid-connection documentation		 Vietnam charging-station deployment can involve electricity-sector, tariff, metering, site-supply, and operator requirements overseen by MOIT and implemented through EVN or the relevant electricity supplier. These requirements sit beside product technical conformity and are normally handled at project or operator level. A proposed citation to Circular 03/2024/TT-BKHCN as mandating Group-2 metrological control for EV charging meters in commercial transactions could not be verified from official-source searches as of 2026-06-13.MOIT electricity-sector instruments for EV charging activities

Project-specific grid capacity and protection review		 The exporter should support the Vietnamese owner with load schedules, single-line diagrams, protection settings, harmonic and power-quality data, metering interface information, commissioning procedures, and maintenance documentation suitable for EVN or the local supplier review. Do not rely on the unverified Circular 03/2024/TT-BKHCN metrology citation without an official text.[INFORMATIONAL] Product test reports do not close the Vietnamese grid and operating gap. EVN or local-supplier coordination and MOIT-relevant project documentation should be planned before shipment; the proposed Circular 03/2024/TT-BKHCN EV-metering claim could not be verified.

OCPP Back-Office Interoperability China's common GB-standard communication baseline for DC charging is GB/T 27930 between the off-board charger and the electric vehicle. That vehicle-side communication layer does not prove OCPP compatibility with a central management system.GB/T 27930-2023 OCPP is the Open Charge Alliance protocol family used for communication between charging stations and central management systems. In Vietnam it should be treated as an operator, network, fleet, or tender requirement unless a specific instrument makes it compulsory for the project.Open Charge Point Protocol (OCPP)
Open Charge Alliance OCPP certification program
Operator or tender backend integration requirements		 Exporters should test the requested OCPP version and security profile, including TLS certificates, boot notification, authorization, transactions, meter values, remote start and stop, firmware update, diagnostics, offline behavior, and interoperability with the nominated Vietnamese backend.[INFORMATIONAL] Do not infer OCPP readiness from GB/T 27930 support. Vietnam network deployment should verify the exact OCPP version, security profile, and live backend interoperability. Open Charge Alliance2026-06-13 · unverified
TCVN / IEC 61851 Charging-Equipment Baseline China's common GB-standard baseline is GB/T 18487.1-2023 for conductive charging-system general requirements. It is useful for engineering comparison but should not be treated as Vietnamese TCVN / IEC evidence without a clause-by-clause mapping.GB/T 18487.1-2023 Vietnam's national standards portal is the control source for current TCVN status and equivalence to international standards. For EV conductive charging equipment, exporters should confirm the current TCVN adoption or reference route for IEC 61851 parts before relying on China GB/T test evidence. A proposed citation to QCVN 26:2025/BKHCN as a mandatory EV-charging-equipment regulation effective 15-Jun-2025 could not be verified from official-source searches as of 2026-06-13.TCVN national standards catalogue
IEC 61851 series for electric vehicle conductive charging systems		 Prepare a TCVN / IEC 61851 clause matrix, accredited test reports, Vietnamese-language technical files, and a list of deviations from GB/T 18487. Confirm whether the exact product and installation route makes a standard voluntary, tender-mandated, or legally required; do not rely on the unverified QCVN 26:2025/BKHCN citation without an official text.[INFORMATIONAL] Treat GB/T 18487 evidence as a starting point only. Vietnam-facing EVSE files should be mapped to the current TCVN / IEC 61851 route confirmed in the VSQI standards catalogue; the proposed QCVN 26:2025/BKHCN mandatory-regulation claim could not be verified.
