Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Seychelles (SBS / SEC / PUC) Gap / action Source + verification date
Connector Interoperability — IEC 62196 Type 2 / CCS2 Direction China AC chargers use GB/T 20234.2 couplers and China DC chargers use GB/T 20234.3 couplers with GB/T 27930 CAN communication. GB/T AC connector geometry, gender, signaling, and contact arrangement differ from IEC 62196 Type 2, and GB/T DC couplers are not CCS2. GB/T charger hardware therefore cannot be treated as a connector-compatible substitute for Seychelles IEC deployments.GB/T 20234.2-2015
GB/T 20234.3-2023
GB/T 27930-2023
GB/T 18487.1-2023		 Seychelles follows a UK/IEC electrical legacy and the practical EV charging direction is IEC 62196 Type 2 for AC charging and CCS2 for DC fast charging. This is not an Americas J1772 / CCS1 market. Connector conformity should be confirmed in the SBS, SEC, PUC, tender, site-owner, or charge-point-operator specification for each project, but China GB/T connector hardware is physically incompatible with the IEC Type 2 / CCS2 ecosystem.IEC 62196-2 — AC Type 2 coupler dimensional compatibility
IEC 62196-3 — DC and AC/DC vehicle couplers, including CCS2 configuration
IEC 61851-1 — EV conductive charging system general requirements
IEC 61851-23 and IEC 61851-24 — DC EVSE and DC communication		 Conversion from GB/T to Seychelles IEC Type 2 / CCS2 requires hardware redesign of the coupler, cable, locking system, proximity-pilot and control-pilot circuits, labels, temperature-rise evidence, spare parts, and for DC chargers the communication stack from GB/T 27930 to the CCS2 / IEC 61851-24 / ISO 15118 direction where required. Adapters should not be treated as a project-compliant substitute.[INFORMATIONAL] Seychelles IEC Type 2 / CCS2 deployments require connector hardware and protocol redesign for GB/T chargers. This is an IEC / UK-legacy direction, not an Americas J1772 / CCS1 direction, and GB/T connectors cannot be accepted as plug-compatible.

PUC Grid Connection — 240/415 V 50 Hz Island Network China domestic charger installations are commonly documented under GB/T 18487.1-2023, GB/T 20234 connector standards, GB/T 27930-2023 for DC communication, and local grid-operator acceptance. China domestic supply is 220 V single-phase / 380 V three-phase at 50 Hz. The shared 50 Hz frequency does not mean voltage equivalence: Seychelles 240/415 V requires input-voltage, protection-threshold, thermal, and metering validation beyond the China baseline.GB/T 18487.1-2023

China local grid operator project-acceptance requirements		 Seychelles electricity supply is operated by the Public Utilities Corporation (PUC), with sector oversight by the Seychelles Energy Commission (SEC). The low-voltage context is 240 V single-phase / 415 V three-phase at 50 Hz. That is the same frequency as China but a different nominal voltage from China's 220/380 V baseline. Grid-connected charger projects should be treated as site-specific electrical installations requiring PUC supply-capacity review, protection coordination, metering, earthing, harmonic and power-quality review, commissioning, and written project acceptance before energisation.Public Utilities Corporation (PUC) electricity network connection and project acceptance

IEC 61000 series — electromagnetic compatibility and power quality
IEC 61851-1 — EV conductive charging system general requirements		 Exporters must confirm that the charger covers 240 V single-phase / 415 V three-phase at 50 Hz, not only China's 220/380 V settings. Protection thresholds, leakage-current devices, metering accuracy, harmonic emissions, supply-capacity calculations, earthing, surge protection, and commissioning documents should be prepared for PUC review. For small island grids and resort or solar-linked sites, load management and demand limits should be agreed with PUC before shipment.[INFORMATIONAL] Seychelles-ready EVSE needs PUC project acceptance and explicit 240/415 V 50 Hz validation. Do not describe the voltage as matching China: only the 50 Hz frequency matches, while nominal voltage differs from China's 220/380 V baseline.

Seychelles Market Access — SBS / SEC / PUC Roles and Nascent EV Demand China EV charger suppliers commonly rely on domestic GB/T design evidence, China-market labelling, Chinese cloud or payment systems, and domestic operator references. These may support technical review but do not establish Seychelles market access. China CCC or GB/T documentation, if available, must be mapped to Seychelles project requirements, IEC evidence, importer responsibilities, and PUC connection approval.GB/T 18487.1-2023

China CCC where in scope		 Seychelles is a small Indian Ocean island economy with high-income tourism demand, strong solar and SIDS decarbonisation policy signals, and a nascent EV charging market. Relevant gates are split across SBS for standards, SEC for energy-sector regulation, and PUC for utility connection and installation acceptance. Importers should verify whether the charger model, HS code, smart/radio functions, labelling, and installation site trigger specific SBS conformity, SEC regulatory, customs, or PUC project-approval requirements before shipment.Seychelles Bureau of Standards national standards and conformity role
Seychelles Energy Commission energy-sector regulation
Public Utilities Corporation utility connection and installation acceptance
Seychelles renewable-energy and energy-efficiency policy context for SIDS decarbonisation		 Exporters should build a Seychelles package around the specific importer and site: IEC 61851 and IEC 62196 evidence, IEC 61000 EMC data, 240/415 V 50 Hz validation, coastal derating, English labelling and manuals, radio-module data, tariff or metering assumptions, spare-part support for islands, and written PUC / project-owner acceptance. Because the EV market is nascent, tender specifications may be more decisive than a mature national EVSE rulebook.[INFORMATIONAL] Seychelles is an opportunity market for IEC-aligned EV chargers, but exporters should not treat it as a paperwork-only extension of China GB/T supply. Confirm SBS, SEC, customs, radio-module, and PUC project requirements for the exact charger and site before shipment. Seychelles Energy Commission2026-06-14 · unverified
OCPP, EMC, Radio Modules, and Power Quality China DC fast chargers commonly use GB/T 27930-2023 CAN communication between the off-board charger and vehicle BMS. This is not OCPP back-office communication and is not the CCS2 communication direction. China-market chargers may also include China-specific payment, SIM, cloud, and operator integrations that need reconfiguration for Seychelles operators, roaming, language, currency, and data interfaces.GB/T 27930-2023
GB/T 18487.1-2023
China operator-specific back-office protocols
China radio module approvals where applicable		 Networked EV chargers in Seychelles should be specified for OCPP back-office interoperability where a charge-point operator, resort operator, public-sector project, or PUC-linked programme requires remote monitoring, billing, diagnostics, or load management. Electrical and electronic emissions and immunity evidence should align with IEC 61000 EMC and power-quality standards. Cellular, Wi-Fi, RFID, payment, or smart-metering modules may trigger additional communications, spectrum, cybersecurity, and data-interface checks under project or national requirements.OCPP — Open Charge Point Protocol for networked EV chargers
IEC 61000 series — electromagnetic compatibility and power quality
IEC 61851-24 — digital communication between DC EV charging station and EV
Seychelles Communications Regulatory Authority or applicable spectrum authority requirements for radio modules where in scope		 Exporters must confirm the OCPP version, charge-point-management-system integration, remote diagnostics, load management, payment or RFID flow, SIM or communications module approval path, and IEC 61000 EMC reports for the final Seychelles configuration. For DC CCS2 products, GB/T 27930 must not be presented as the relevant communication evidence. Harmonic current and immunity data should be reviewed against the specific PUC supply point and island-grid constraints.[INFORMATIONAL] Seychelles networked chargers should be validated for OCPP integration, IEC 61000 EMC and power quality, and local communications-module requirements. GB/T 27930 alone does not satisfy OCPP, CCS2 communication, or back-office interoperability needs. Open Charge Alliance2026-06-14 · unverified
IEC 61851 Safety and Coastal Environmental Derating China's comparable design baseline is GB/T 18487.1-2023, supported by GB/T connector and DC communication standards. GB/T 18487 evidence is useful for engineering review but includes China-specific connector and communication assumptions and does not by itself establish IEC 61851 conformity for an IEC Type 2 / CCS2 Seychelles configuration. China domestic outdoor ratings may also need reassessment for Seychelles coastal salt, humidity, and surge exposure.GB/T 18487.1-2023

GB/T 27930-2023		 Seychelles Bureau of Standards (SBS) is the national standards body, while SEC and PUC are key gates for energy-sector and grid-connected installations. EVSE safety evidence should be aligned with IEC 61851-1 for general conductive charging requirements and IEC 61851-23 for DC EVSE. Because Seychelles is an Indian Ocean island state with humid, salt-laden coastal conditions, outdoor charger packages should include enclosure ingress protection, corrosion resistance, salt-mist review, surge protection, thermal derating, and maintenance instructions suitable for coastal and resort installations.IEC 61851-1 — Electric vehicle conductive charging system — Part 1: General requirements
IEC 61851-23 — DC electric vehicle supply equipment
IEC 60529 — Degrees of protection provided by enclosures (IP Code)
IEC 60068 environmental testing, including salt-mist and damp-heat context where specified
Seychelles Bureau of Standards national standards role		 Exporters should prepare an IEC 61851 clause matrix, accredited IEC safety test reports for the final Type 2 / CCS2 configuration, IP and IK evidence, corrosion and salt-mist material review, surge-protection data, enclosure gasket and cable-gland specifications, thermal derating for humid coastal sites, and installation manuals aligned with PUC site conditions. A GB/T report for a China connector configuration is not enough.[INFORMATIONAL] Treat IEC 61851 and coastal environmental suitability as separate evidence items. Seychelles installations need final-configuration IEC safety evidence and salt-mist / humidity / surge review; China GB/T 18487 evidence alone is not enough.
