Billion Watts passed the VPC Verification of ESS Safety on-site Test.
The IEC 62933 specification examines the effectiveness of various disaster prevention designs from the perspective of risks and hazards, including ESS design, factory shipment, transportation, on-site assembly, trial operation, maintenance, and decommissioning, so as to achieve the expected Safety. In addition, detailed test items and specifications for Type Test and on-site test ensure that the product has comprehensive safety considerations from the preliminary design stage to the final on-site assembly stage.
Billion Watts AFC energy storage fields have continuously passed
the IEC/CNS 62933 voluntary test.
IEC/CNS 62933-5-2
The IEC/CNS 62933 voluntary test is issued by Bureau Veritas, a leading brand of the global inspection agency, and the verification process complies with the grid-connected energy storage safety regulations.
Billion Watts since the end of 2022, Those sites have successively passed the international certification IEC/CNS 62933-5-2 SAT (The number of SAT passed sites continues to increase).
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 Watts domestic energy storage fields have continuously passed
the international safety certification.
For the certification of essential energy storage components and battery management system testing, Billion Watts has become the private AFC energy storage company in Taiwan with the largest number of ESS fields that continuously passed the IEC/CNS 62933-5-2 on-site test. The verification process fully complies with the requirements of international certification agencies for the safety specifications of grid-connected energy storage systems.
The energy storage field must adopt equipment that conforms to the technical specifications of IEC/CNS 62933-5-2 verification, including single battery, battery system, BMS, PCS, and outer cabinet material; In addition to complying with safety regulations, the installation site, site review and site acceptance test (SAT) are all within the scope of the review.
Since the announcement of the on-site test requirements by the Bureau of Standards, Metrology and Inspection, on-site inspections must be completed within 6 months for sites that are already "in operation"; sites that are "under construction" that have not yet completed power transmission must obtain a report before they can join the Energy Trading Platform. If the site adopts energy storage products that do not comply with the voluntary verification system and technical specifications of the "outdoor battery ESS site", or if the system integrator who performs the on-site test is inexperienced, it will face the risk of being unable to trade on the TPC’s Energy Trading Platform. Billion Watts has rich experience in constructing energy storage sites and cooperates with relevant ministry policies to voluntarily conduct safety verification. We are your best partner in the construction of energy storage equipment.
