Billion's AFC ESS Achieves Continuous Compliance with IEC/CNS 62933 Voluntary Testing
IEC 62933 standard examines various aspects of energy storage systems, including design, factory shipment, transportation, on-site assembly, commissioning, operation and maintenance, as well as decommissioning. It focuses on examining the effectiveness of disaster prevention designs from the perspective of risks and hazards, aiming to achieve the expected level of safety. The standard also includes detailed testing items and specifications for type testing and on-site testing, ensuring comprehensive safety considerations from the initial design stage to the final on-site assembly stage.
Operating own sites & building new sites for external investors
- With decades of R&D and manufacturing foundation for electronic power energy management and information and communication equipment, Billion established battery production and assembly and component warranty factories.

Grid-connected ESS Installation Safety Regulations
Equipment Safety Specification Content
- For the energy storage subsystem, the industry can choose to follow the US, European regulations or Taiwan standards and submit a qualified test report or verification certificate as the basis for the review.
- After the ESS is built, it is necessary to appoint an impartial third-party organization (ex: TAF, ILAC accredited laboratory) to conduct IEC 62933-5-2 or UL 9540 on-site test and obtain a qualified report.
| Classification | Equipment items | U.S. regulations | European regulations | Taiwan |
|---|---|---|---|---|
| storage subsystem | Cell/single battery | UL 1642 or UL 1973 | EC 62619 | CNS 62619 |
| Battery pack/cabinet | UL 1973 | IEC 62619、IEC 63056 | IEC 62619、IEC 63056 | |
| Battery Management System (BMS) | UL 991 or UL 1998 or UL 60730-1 | IEC 61508 or IEC 60730-1 | CNS 60730-1 (Expected to be announced in FY111 Q4) | |
| Energy storage system (on-site test pass report) | UL 9540 (6 tests) | IEC 62933-5-2 (7 tests) | CNS 62933-5-2 (Expected to be announced in FY111 Q2) |
Remark:
- Taipower Substation Procurement Specifications only require safety regulations for outdoor cabinets but do not specify safety regulations for cabinets inside containers.
- Most domestic testing laboratories such as UL, TUV, and AnTek(ATC) have the test ability of battery and module level.
- UL, AnTek(ATC), and NCSIST already have the cabinet-level UL1973 and IEC/CNS 63056 test capability (single cabinet: 180kW, including the burning test).
Billion's subsidiary, Billion Watts, has consistently obtained international safety certifications for its domestic energy storage facilities.
