EMC and China GB Evidence Mapping China BESS files often include GB 44240-2024, GB/T 36276-2023, GB/T 36558, PCS reports, and EMC reports for subassemblies. Those documents should be mapped to Thai equipment-level EMC and grid-quality requirements rather than presented as automatic Thai acceptance.GB 44240-2024
GB/T 36276-2023
GB/T 36558
PCS and subassembly EMC reports		 Thailand BESS projects may require EMC evidence for PCS, BMS, controls, meters, communications equipment, and auxiliary electrical equipment through TIS, IEC, utility, owner, or tender specifications. The relevant EMC standard should be confirmed by equipment type and installation environment; do not assume one EMC report covers the complete BESS container.TISI Thai Industrial Standards catalogue and compulsory standards list
IEC 61000 series where specified
Project EMC and utility power-quality specifications		 The gap is equipment boundary and environment. Exporters should identify which subassemblies are placed on the Thai market, which are imported as parts of a project, which EMC standards are cited by the tender or utility, and whether site-level harmonic, flicker, earthing, surge, and communication-immunity evidence is required.[INFORMATIONAL] GB 44240-2024, GB/T 36276-2023, and GB/T 36558 evidence is useful for comparison, but Thai EMC and power-quality acceptance must be checked against the exact equipment boundary and project instrument.

BESS Fire Safety and Building / Installation Review China commonly relies on GB 44240-2024, GB/T 36276-2023, GB/T 36558, and project-specific fire design and acceptance documents for stationary energy storage. These documents may support due diligence but do not replace Thai local-authority, owner, or insurer fire-safety review.GB 44240-2024
GB/T 36276-2023
GB/T 36558		 Thailand BESS fire-safety obligations are usually project and site specific. Depending on location, occupancy, voltage, container layout, hazardous materials, insurer requirements, and local-authority practice, review may address separation distances, ventilation, thermal-runaway mitigation, gas detection, fire detection and suppression, emergency shutdown, access, signage, and emergency response. Do not assume battery safety testing alone closes Thai installation fire approval.Thailand fire-prevention and building-control requirements
Local fire-authority or building-authority review
Project insurer and owner fire-safety requirements		 Exporters should prepare layout drawings, fire-protection design basis, thermal-runaway and propagation test evidence where available, ventilation and gas-detection basis, emergency shutdown logic, monitoring and alarm matrix, SDS, firefighter access information, and Thai-language emergency procedures for local review.[INFORMATIONAL] Battery test reports do not close the Thai BESS fire-safety gap. Site-specific fire design, local-authority expectations, and owner or insurer requirements should be addressed before shipment and commissioning.

ERC and Utility Rules for Grid-Connected Storage China commonly uses GB/T 36558 for electrochemical energy storage system grid-connected requirements and project-specific State Grid or China Southern Power Grid rules. These Chinese grid documents do not substitute for ERC licensing analysis or Thai utility interconnection acceptance.GB/T 36558
State Grid / China Southern Power Grid project rules		 Thailand electricity projects are regulated by the Energy Regulatory Commission under the energy-industry legal framework. A grid-connected BESS may require ERC licensing or exemption analysis, utility interconnection review, metering, protection, power-quality, communication, commissioning, and PPA or programme-specific acceptance depending on whether the storage is standalone, co-located with generation, behind-the-meter, or part of a regulated power project.Energy Industry Act B.E. 2550
ERC energy-industry licensing and regulatory notices
EGAT / MEA / PEA grid-connection and project requirements		 The main gap is project approval rather than factory certification. Exporters should prepare PCS type-test evidence, relay and protection settings, anti-islanding and ride-through data, harmonic and flicker data, communication protocol evidence, single-line diagrams, metering design, commissioning procedures, and Thai-language submittals for the project owner, ERC adviser, and utility.[INFORMATIONAL] Chinese GB/T 36558 evidence does not clear Thai grid connection. ERC licensing analysis and utility acceptance should be handled at project level before energisation. Office of the Energy Regulatory Commission (Thailand)2026-06-13 · unverified
TISI / TIS Battery Standards — IEC 62619:2022 and IEC 62133 Mapping China commonly relies on GB 44240-2024 for lithium-ion cells and batteries used in electric energy storage and GB/T 36276-2023 for lithium-ion batteries for electric energy storage. These GB documents can support technical comparison but do not prove Thai TISI/TIS applicability or Thai project acceptance.GB 44240-2024
GB/T 36276-2023		 Thailand's standards body is TISI. For BESS battery due diligence, exporters should check whether a Thai Industrial Standard, customer specification, tender document, or accepted test route references IEC 62619:2022 for industrial lithium cells and batteries or IEC 62133 for portable sealed secondary lithium cells and batteries. Do not treat IEC 62619:2022 or IEC 62133 as a whole-BESS compulsory Thai market-access certificate unless the exact TISI compulsory list, import rule, or project instrument cites that scope.TISI Thai Industrial Standards catalogue and compulsory standards list
IEC 62619:2022
IEC 62133		 The gap is scope and recognition. A China GB report should be mapped clause-by-clause to the Thai project's TIS or IEC reference, cell chemistry, module configuration, BMS protections, thermal tests, labels, and Thai importer documentation. If a project asks for TISI/TIS evidence, confirm the exact TIS number and edition rather than substituting a Chinese GB report.[INFORMATIONAL] Do not overclaim a blanket Thai whole-BESS TISI certificate. Confirm the exact TIS or IEC reference and whether it is compulsory, voluntary, or project-required for the shipped cell, module, rack, or integrated system.

Electrical Energy Storage System Standards — IEC 62933 China commonly uses GB/T 36558 for electrochemical energy storage system grid-connected requirements and GB/T 36276 for lithium-ion battery requirements. These can be mapped to IEC 62933 topics but are not Thai project acceptance evidence by themselves.GB/T 36558
GB/T 36276		 IEC 62933 is the international series for electrical energy storage systems. For Thailand BESS projects, IEC 62933 may appear as a tender, lender, owner-engineer, or utility due-diligence reference, but exporters should not treat the IEC 62933 series as a Thai whole-system mandatory rule unless a Thai regulator, utility, contract, or permit condition specifically incorporates it.IEC 62933 series
Project technical specifications
Utility and owner-engineer acceptance requirements		 A China system report should be mapped to the IEC 62933 topics requested by the Thai project: system boundary, energy capacity, auxiliary power, safety concept, commissioning, performance testing, documentation, operation and maintenance, and end-of-life responsibilities. The exact IEC 62933 part and edition should be confirmed in the project specification.[INFORMATIONAL] IEC 62933 is a useful system benchmark for Thailand BESS tenders, but it should be treated as mandatory only when the Thai project or authority expressly incorporates the relevant part and edition.

Lithium Battery Transport — UN 38.3 and Dangerous Goods Documentation China exporters commonly prepare UN 38.3 reports, SDS/MSDS, transport conditions appraisal reports, and dangerous-goods packaging documents for lithium battery shipments. These documents remain necessary but must match the configuration shipped to Thailand.UN 38.3 test report and test summary
SDS / MSDS
Dangerous-goods packaging and transport documents		 Lithium cells and batteries shipped from China to Thailand should have UN Manual of Tests and Criteria, Part III, subsection 38.3 evidence where dangerous-goods transport rules require it. Exporters should prepare the UN 38.3 test summary, SDS, dangerous-goods classification, packaging evidence, and air or sea transport documentation for the exact shipped configuration.UN Manual of Tests and Criteria, Part III, subsection 38.3
IMDG Code for sea transport
ICAO Technical Instructions / IATA DGR for air transport		 Transport evidence is configuration-specific. A cell-level UN 38.3 report may not cover a module, rack, containerized BESS, replacement pack, altered state of charge, or changed packaging. Thai importers, ports, carriers, and airlines may reject inconsistent test summaries, SDS classifications, package marks, or shipping names.[INFORMATIONAL] Thai project or TISI evidence does not replace UN 38.3 transport evidence. The shipped configuration must be covered by the UN 38.3 test summary and dangerous-goods documents. United Nations Economic Commission for Europe (UNECE)2026-06-13 · unverified
