Compliance item Common China baseline Equatorial Guinea (no NSB / SEGESA) Gap / action Source + verification date
Connector Interoperability — GB/T 20234 vs IEC 62196 Type 2 / CCS2 China AC chargers use GB/T 20234.2 couplers and China DC fast chargers use GB/T 20234.3 couplers with GB/T 27930 DC communication. GB/T AC and DC connector hardware is not physically interchangeable with IEC 62196 Type 2 / CCS2 infrastructure, and the DC communication stack is different. A charger built only for GB/T connector geometry cannot serve IEC Type 2 / CCS2 vehicles without hardware and protocol redesign.GB/T 20234.2-2015 — AC charging coupler
GB/T 20234.3-2023 — DC charging coupler
GB/T 27930-2023 — DC charging communication
GB/T 18487.1-2023		 Equatorial Guinea is a Hispanophone Central African market with Spanish/IEC electrical legacy, not an Americas J1772 market. For new IEC-aligned EV infrastructure, AC charging should be specified around IEC 62196-2 Type 2 and DC charging around IEC 62196-3 CCS Combo 2 (CCS2), unless a project owner explicitly specifies a different vehicle fleet. Connector choice must be confirmed in the tender or site specification because the national EV market is nascent and installed public charging infrastructure is limited.IEC 62196-2 — Type 2 AC vehicle coupler dimensional compatibility
IEC 62196-3 — CCS Combo 2 DC vehicle coupler dimensional compatibility
IEC 61851-1 — conductive charging system general requirements
IEC 61851-23 and IEC 61851-24 — DC charging and digital communication context		 Do not ship a GB/T-only connector configuration unless the buyer has explicitly confirmed a GB/T vehicle fleet. For a normal IEC-aligned Equatorial Guinea project, redesign the cable assembly, inlet/outlet, locking device, proximity pilot/control pilot signalling, CCS2 DC communication, labels, spare parts, and temperature-rise evidence around IEC 62196 Type 2 / CCS2. Adapters should not be treated as the compliance strategy for public or commercial installations.[INFORMATIONAL] Treat Equatorial Guinea as IEC Type 2 / CCS2 direction unless the project explicitly says otherwise. GB/T 20234 connector hardware and GB/T 27930 DC communication are not accepted substitutes for IEC 62196 Type 2 / CCS2 interoperability.

SEGESA Grid Connection — 230/400 V, 50 Hz China domestic charger installations are commonly validated for 220 V single-phase / 380 V three-phase, 50 Hz under GB/T 18487.1-2023, GB/T 20234 connectors, GB/T 27930 DC communication, and local grid-operator acceptance. Equatorial Guinea shares the same 50 Hz frequency as China, but its nominal voltage differs: 230/400 V versus China 220/380 V. Input voltage range, protection thresholds, transformer or rectifier ratings, leakage-current behaviour, metering accuracy, and thermal loading must be checked for the 230/400 V condition.GB/T 18487.1-2023

China local grid operator project-acceptance requirements		 Equatorial Guinea's public electricity supply is served by SEGESA (Sociedad de Electricidad de Guinea Ecuatorial). The practical low-voltage engineering baseline is 230 V single-phase / 400 V three-phase, 50 Hz. EV charger projects should obtain site-level acceptance from SEGESA or the relevant project utility reviewer for supply capacity, earthing arrangement, protection coordination, metering, harmonic current, civil/electrical installation, commissioning, and operating responsibility. Equatorial Guinea has a small, nascent grid-tie EV charging market, so project-specific utility conditions are more important than assuming a mature national EVSE rulebook.SEGESA — Sociedad de Electricidad de Guinea Ecuatorial utility connection acceptance
IEC 61851-1 — conductive EV supply equipment general requirements
IEC 61000 series — electromagnetic compatibility and power quality
Project-specific electrical installation and utility acceptance conditions		 Exporters must document that the charger is rated and tested for 230/400 V, 50 Hz operation, not merely China's 220/380 V, 50 Hz baseline. Obtain SEGESA or project-utility acceptance for supply capacity, transformer sizing, earthing, protection, load management, harmonic limits, metering, and commissioning. Because the market is nascent, project documents should explicitly define who approves the installation and who operates or maintains the charger after energisation.[INFORMATIONAL] Same 50 Hz does not mean same grid configuration. A China 220/380 V charger package must be revalidated for Equatorial Guinea's 230/400 V network and accepted by SEGESA or the project utility reviewer before commissioning.

Equatorial Guinea Market Access — No Strong National EVSE Standards Body Confirmed China-market EV chargers are usually documented with GB/T 18487.1-2023, GB/T 20234 connector standards, GB/T 27930 DC communication, China domestic EMC and electrical reports, and China commercial labels. Those documents may help explain the design but do not create automatic market access in Equatorial Guinea, do not satisfy IEC Type 2 / CCS2 interoperability, and do not replace importer, customs, or SEGESA project requirements.GB/T 18487.1-2023

China CCC where in scope		 As of the dataset date, no strong, dedicated national standards body or published EV charger certification scheme has been confirmed for Equatorial Guinea. The country is a small, oil-and-gas-based economy with a nascent EV market and limited public charging deployment. Practical market access therefore depends on the importer, customs documentation, SEGESA or project utility acceptance, site owner specification, lender or EPC requirements, and IEC-based technical evidence rather than a single published EVSE product mark. Spanish-language documentation may be needed for commercial, customs, and installation files.Equatorial Guinea customs and importer documentation requirements
SEGESA utility/project acceptance for grid-connected electrical equipment
IEC 61851, IEC 62196, and IEC 61000 evidence where specified by project owner, EPC, lender, or insurer
Spanish-language commercial and installation documentation where required		 Before quoting or shipping, exporters should confirm the importer of record, HS code, customs broker requirements, Spanish documentation needs, charger configuration, connector standard, 230/400 V electrical rating, SEGESA connection process, site-owner acceptance criteria, warranty/service model, and any lender or EPC IEC test-report requirements. The absence of a mature national EVSE certification scheme should be treated as a verification risk, not as a compliance waiver.[INFORMATIONAL] Do not treat the lack of a strong national EVSE standards body as permission to ship China GB/T chargers unchanged. Build a project file around importer/customs requirements, SEGESA acceptance, IEC 61851 / IEC 62196 / IEC 61000 evidence, Spanish documentation, and tropical-environment validation.

OCPP, EMC, Power Quality, and Communications China DC chargers commonly use GB/T 27930-2023 CAN-based communication between the off-board charger and the vehicle battery management system. China operators may also use proprietary back-office protocols or OCPP variants. That China communication package does not prove compatibility with an Equatorial Guinea charge-point operator's OCPP back office, nor does it prove IEC 61000 EMC behaviour at 230/400 V, 50 Hz on the local network.GB/T 27930-2023
GB/T 18487.1-2023
China operator-specific charger back-office protocols
China EMC and radio approvals where in scope		 Equatorial Guinea has no confirmed national smart-charging platform comparable to Qatar's Tarsheed. For networked commercial chargers, OCPP should be specified by the charge-point operator, site owner, or fleet operator as the practical interoperability baseline. IEC 61000-series EMC and power-quality evidence should be prepared for chargers connected to SEGESA supply, including harmonic current, conducted and radiated emissions, immunity, surge, and voltage-dip behaviour. Cellular modem, RFID, payment, and cloud features may create separate radio, cybersecurity, or data-hosting requirements that must be confirmed by the project owner and local counsel.OCPP — Open Charge Point Protocol for networked charger back-office interoperability
IEC 61000 series — EMC, immunity, harmonics, voltage fluctuation, and surge context
IEC 61851-24 and ISO 15118 where CCS2 DC communication is required
Project-specific CPO, fleet, telecom, and payment-system requirements		 For networked chargers, confirm the required OCPP version, backend certification process, SIM/APN or connectivity requirements, payment integration, remote diagnostics, and cybersecurity responsibilities before shipment. For EMC and power quality, provide IEC 61000 evidence and harmonic/load data at the actual 230/400 V configuration. For CCS2 DC chargers, replace GB/T 27930-only communication with the IEC 61851-24 / ISO 15118 stack where required by vehicles or the CPO.[INFORMATIONAL] OCPP is not confirmed as a national platform mandate in Equatorial Guinea, but it is the practical interoperability baseline for commercial networked chargers. GB/T 27930-only DC communication and China EMC evidence do not prove compatibility with IEC Type 2 / CCS2 deployments or SEGESA-connected sites. Open Charge Alliance2026-06-14 · unverified
IEC 61851 Safety Baseline and Tropical Humidity Derating China's comparable charger baseline is GB/T 18487.1-2023, supported by GB/T 20234 connector standards and GB/T 27930 DC communication. These documents are useful design inputs but incorporate China-specific connector, signalling, and operating assumptions. China domestic safety evidence also may not cover the tropical humidity, salt-laden coastal environment, condensation cycling, and corrosion exposure expected for Equatorial Guinea installations.GB/T 18487.1-2023

GB/T 20234.1-2023
GB/T 27930-2023		 Equatorial Guinea has no strongly confirmed national EV charger standardization body or dedicated public EVSE safety certification scheme. For project acceptance, IEC 61851-1 is the practical international baseline for conductive EV supply equipment, and IEC 61851-23 applies to DC charging stations. Because Equatorial Guinea has an equatorial tropical climate, charger documentation should address high humidity, condensation, corrosion, insulation resistance, enclosure ingress protection, surge protection, cable ageing, and thermal derating for outdoor coastal and island sites, including Malabo and mainland installations.IEC 61851-1 — Electric vehicle conductive charging system — General requirements
IEC 61851-23 — DC electric vehicle supply equipment
IEC 60529 — IP Code for enclosure ingress protection
IEC 62752 / IEC 61439 context where applicable to charging and low-voltage assemblies
Project owner and utility safety acceptance requirements		 Prepare an IEC 61851-1 clause matrix, accredited IEC safety reports, IEC 61851-23 evidence for DC stations, IP and corrosion-resistance evidence, surge-protection ratings, residual-current protection details, emergency-stop and interlock documentation, and humidity/condensation derating analysis. A GB/T 18487 report alone is not enough to demonstrate IEC safety acceptance or suitability for Equatorial Guinea's equatorial climate.[INFORMATIONAL] Use IEC 61851 evidence as the safety baseline and add tropical humidity, condensation, corrosion, and surge-protection validation. China GB/T 18487 evidence is supporting design material, not a substitute for IEC-oriented project acceptance. International Electrotechnical Commission2026-06-14 · unverified
