Compliance Gap Matrix

Gap matrix
Compliance item Common China baseline Guyana (GNBS / GEA / GPL) Gap / action Source + verification date
Connector Interoperability — GB/T 20234 vs SAE J1772 / CCS1 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 geometry, contact allocation, vehicle inlet expectations, locking strategy and signalling differ from SAE J1772 Type 1 and CCS Combo 1. A GB/T connector cannot plug into a J1772 / CCS1 vehicle inlet, and a J1772 / CCS1 vehicle cannot use a GB/T outlet without a charger-side hardware and protocol change.GB/T 20234.2-2015 — Connection set for conductive charging of electric vehicles — Part 2: AC charging coupler

GB/T 27930-2023 — Communication protocols between off-board conductive charger and battery management system for electric vehicles
GB/T 18487.1-2023 — Electric vehicle conductive charging system — Part 1: General requirements		 Official Guyana sources reviewed for this dataset did not confirm a single national EV charger connector mandate as of 2026-06-14. In practice, Guyana's 120/240 V, 60 Hz electrical environment and vehicle import patterns place it in the Americas connector ecosystem, where SAE J1772 Type 1 is the common AC conductive charging coupler and CCS Combo 1 is the common DC fast-charging coupler. For any Guyana deployment, the connector must match the vehicles and the site owner's or charge-point operator's specification; exporters should confirm the exact J1772, CCS1, NACS, CHAdeMO, or other outlet requirement with GEA, GNBS, GPL, the vehicle importer, and the project owner before shipment.SAE J1772 — Electric Vehicle and Plug in Hybrid Electric Vehicle Conductive Charge Coupler

IEC 61851-1:2017 — Electric vehicle conductive charging system — Part 1: General requirements
IEC 61851-23:2023 — Electric vehicle conductive charging system — Part 23: DC electric vehicle supply equipment		 A China GB/T-only charger is not connector-ready for Guyana projects that use J1772 / CCS1. Conversion requires a hardware redesign of the coupler, cable assembly, inlet/outlet lock, proximity and control pilot signalling, DC communication stack, labels, test reports, thermal rise evidence, and spare-part strategy. Because the exact Guyana connector requirement is not confirmed as a national rule, the compliant path is to confirm the project connector with GEA/GNBS/GPL and the CPO, then build the charger to that connector rather than relying on adapters.[INFORMATIONAL] Connector conversion is a hardware and protocol redesign, not a paperwork exercise. Assume GB/T connectors are physically incompatible with J1772 / CCS1 vehicles, and confirm the exact Guyana connector requirement with GEA/GNBS before quoting or shipping.

GPL Grid Connection — 120/240 V, 60 Hz and Site Coordination China domestic EVSE is normally designed around 220 V single-phase / 380 V three-phase, 50 Hz supply, GB/T 18487.1-2023 conductive charging requirements, GB/T 20234 connectors, and local Chinese grid-operator acceptance. A China-market charger nameplate, transformer, rectifier, fan, meter and protection design may not automatically cover 60 Hz operation, 120 V Level 1 input, split-phase 240 V service, or GPL site acceptance documentation.GB/T 18487.1-2023

China local grid operator project-acceptance requirements		 Guyana Power and Light (GPL) is the utility for the main public grid areas and publishes a National Grid Code governing planning, interconnection, operation, minimum technical requirements, metering, voltage regulation, frequency behaviour, power quality, and data requirements. Guyana uses an Americas-style low-voltage environment commonly described for premises as 120/240 V, 60 Hz; charger suppliers should confirm the actual service voltage, phase availability, transformer capacity, protection, metering and load-management requirements for each GPL-connected site. Large public or fleet charging sites may require project-level coordination with GPL, and GEA policy material notes that grid interconnection requests must comply with GPL interconnection requirements for grid-connected energy systems.GPL National Grid Code — planning, interconnection, operation, minimum technical requirements and metering
GPL voltage regulation standards and power quality requirements
GEA policy reference to GPL interconnection requirements for public-grid interconnection
IEC 61000 series — electromagnetic compatibility and power quality		 Exporters must confirm that the charger input range, control power, fans, meters, protection devices, RCD/GFCI strategy, surge protection and thermal design support Guyana's 60 Hz and 120/240 V supply conditions. For commercial AC and DC sites, prepare single-line diagrams, load calculations, harmonics data, demand-management settings, commissioning records, and any GPL forms requested by the site engineer or utility. A China domestic 50 Hz / 220-380 V design without 60 Hz and 120/240 V evidence is not grid-ready for Guyana.[INFORMATIONAL] Guyana-ready chargers need explicit 60 Hz and 120/240 V input evidence plus GPL-facing site documentation. Treat China 50 Hz / 220-380 V grid evidence as a starting point only. Guyana Power and Light Incorporated2026-06-14 · unverified
Guyana Market Access — GNBS, GEA and Early EV Infrastructure China's EV charging market access is based on Chinese standards, domestic grid-operator acceptance, GB/T 18487 safety evidence, GB/T 20234 connectors, GB/T 27930 DC communication, and China operator or tender requirements. Chinese domestic market volume and GB/T conformity do not create automatic Guyana market access, especially where GNBS import controls, GPL utility coordination, 60 Hz input evidence, and Americas connector compatibility must be addressed separately.GB/T 18487.1-2023

China domestic charging infrastructure and local grid requirements		 Guyana's EV charger market is still nascent, but GEA identifies electric mobility in Guyana in its public energy materials and describes major power-sector transition investments including gas-to-energy, grid modernization, renewable generation, and GPL network expansion. GNBS monitors electrical and electronic appliances and electrical fittings/equipment against compulsory national standards and requires annual registration by importers and local manufacturers of monitored product categories. For EVSE imports, the market-access route should be confirmed across GNBS product inspection/registration, GEA energy-sector coordination, GPL site connection, customs classification, and any project-owner or public procurement specifications.GNBS Product Inspection and Registry for Importers and Manufacturers

IEC 61000 series for EMC and power quality		 Build the Guyana file as an import-and-project dossier: confirm HS code and GNBS monitored-product status; register the importer/manufacturer where required; prepare IEC safety and EMC reports; document 60 Hz / 120-240 V operation; confirm connector type with GEA/GNBS and the CPO; coordinate site capacity and metering with GPL; and include installation, commissioning, warranty and spare-part plans suitable for a young but fast-growing market. Do not assume that a China GB/T charger can be shipped unchanged into Guyana.[INFORMATIONAL] Guyana is an early EVSE market with real energy-infrastructure momentum. Treat that as an opportunity signal, not a conformity shortcut: GNBS, GPL, connector, IEC evidence, and 60 Hz operation each need explicit confirmation. Guyana Energy Agency2026-06-14 · unverified
OCPP, EMC and Power Quality for Networked Chargers China DC fast chargers commonly use GB/T 27930-2023 for charger-to-BMS communication over CAN. China network operators may require proprietary or OCPP-like back-office functions, but China domestic protocol evidence does not prove OCPP interoperability, CCS1 vehicle communication, IEC 61000 EMC, or GPL power-quality compatibility. China GB/T connector and protocol choices also differ from the Americas J1772 / CCS1 ecosystem likely to be specified for Guyana projects.GB/T 27930-2023 — Communication protocols between off-board conductive charger and battery management system

China operator-specific back-office protocols		 Official Guyana sources reviewed did not identify a national OCPP mandate for all EV chargers. However, commercial public chargers, fleet chargers and utility-coordinated sites commonly need network monitoring, billing, remote fault management, access control, demand response and load-management functions. GPL's National Grid Code addresses power quality and minimum technical requirements for grid users, while IEC 61000 is the normal international EMC and power-quality family used to evidence conducted/radiated emissions, immunity, harmonics, flicker and voltage disturbance performance. For DC chargers using CCS1, the vehicle-side charging communication must follow the CCS / IEC 61851 family specified for the selected connector rather than China GB/T 27930.GPL National Grid Code — power quality and minimum technical requirements

A charger with only GB/T DC communication and no documented OCPP/EMC evidence is not ready for networked public charging in Guyana.[INFORMATIONAL] Networked Guyana deployments should be treated as OCPP, IEC 61000 and GPL power-quality projects. GB/T 27930 is China DC vehicle communication evidence, not a substitute for CCS1 or back-office interoperability. Guyana Power and Light Incorporated2026-06-14 · unverified
IEC 61851 Safety Baseline and GNBS Electrical Equipment Control China's comparable EVSE baseline is GB/T 18487.1-2023 for conductive charging systems, with China-specific GB/T connector, signalling and DC communication requirements. China-market safety files may include domestic type tests, CCC-adjacent electrical component evidence, GB/T 20234 connector evidence, and GB/T 27930 DC communication reports, but these are not automatically IEC 61851 clause-level evidence for a Guyana import or project file.GB/T 18487.1-2023 — Electric vehicle conductive charging system — Part 1: General requirements

GB/T 27930-2023		 GNBS monitors imported and locally manufactured products against compulsory national standards and lists electrical and electronic appliances plus electrical equipment and fittings among monitored categories. Product certification may provide assurance that products conform to standards or other normative documents, although GNBS describes its listed product certification programme as voluntary for named local product categories. For EV chargers, official charger-specific mandatory standards were not confirmed from GNBS sources as of 2026-06-14; exporters should use IEC 61851-1 as the international safety baseline for conductive EVSE and IEC 61851-23 for DC EV supply equipment, then confirm the applicable GNBS import inspection, test certificate, labelling, and registration route for the HS code and product configuration.GNBS Product Inspection — compulsory national standards monitoring for imported and locally manufactured products

IEC 60529 — Degrees of protection provided by enclosures (IP Code)		 Prepare an IEC 61851-1 clause matrix, IEC 61851-23 evidence for DC products, insulation and protective earthing test data, residual-current and ground-fault protection evidence, over-temperature protection data, enclosure IP rating, installation manual, labels, and GNBS-facing test certificates or declarations. Confirm whether GNBS requires importer registration, product inspection release, specific compulsory national standards, or additional local labelling before import. A standalone GB/T 18487 report is useful design evidence but not a direct IEC 61851 or GNBS conformity substitute.[INFORMATIONAL] Treat IEC 61851 evidence and GNBS import/product-control checks as separate gates. GB/T safety reports should be mapped clause by clause and supplemented with IEC-format test evidence before Guyana shipment. Guyana National Bureau of Standards2026-06-14 · unverified
