On May 25, 2023, Rept Battero Y52 liquid-cooled battery cluster obtained the UL 9540A, TÜV Mark and cTÜVus certification certificates issued by the international independent third-party testing, inspection and certification organization TÜV Rheinland (hereinafter referred to as "TÜV Rheinland"). Among them, the TÜV Mark certification is based on the IEC 62619&63056 standard, and the cTÜVus certification is based on the UL 1973 standard.

Dong Bin, Deputy General Manager of TÜV Rheinland Greater China Solar Energy and Commercial Product Services, and Yi Huiqiong, General Manager of Ripu Lanjun Energy Storage Market, attended the certification ceremony and reached a further willingness to cooperate in the follow-up product functional safety certification. As a professional third-party certification body in the field of energy storage batteries and systems, TÜV Rheinland has conducted a comprehensive safety test on the Y52 liquid-cooled battery cluster of Rippower Energy from the battery cell, module, unit and installation level, providing a safer guarantee for the application of energy storage systems and helping products to enhance their global competitiveness.

Ruipu Lanjun Y52 liquid-cooled battery cluster has successfully obtained three TÜV Rheinland certifications, marking Ripu Lanjun's further progress and breakthrough in energy storage safety, and it is also another milestone for the company's development in the field of new energy storage.

UL 9540A

UL 9540A is one of the most authoritative and stringent test standards for thermal runaway flame spread of battery energy storage systems in the global energy storage industry. It is an important way to verify the safety of energy storage products. It has been recognized by the National Fire Administration, federal judicial agencies, and energy storage associations in various regions around the world. It has become an indispensable passport to enter the North American market and even the global market.

TÜV Mark

The full name of TÜV Mark is TÜV Bauart Mark. TÜV Mark is a safety certification mark for electrical appliances and components in Germany, and has a very high degree of recognition in the EU market.

· IEC 62619, as a safety standard for batteries used in industrial equipment in the IEC standard system, is a current international technical standard on the safety of energy storage batteries, covering safety requirements related to energy storage batteries.

· IEC 63056, which specifies the safety requirements and test methods for secondary lithium batteries and battery packs used in electric energy storage systems with a maximum DC voltage of 1500V.

cTÜVus

cTÜVus certification is an authoritative certification mark for products to comply with relevant laws and regulations in North America. With TÜV Rheinland's cTÜVus certification mark, it can prove that the Y52 liquid-cooled battery cluster complies with the relevant safety standards of the United States and Canada, enhancing customers' confidence in product quality and safety.

UL 1973 is the safety standard for energy storage battery systems in North America, and it is also a binational standard recognized by ANSI in the United States and SCC in Canada. In addition, this standard is also recognized by other regions, such as Australia's CEC, and products that have obtained this certificate can smoothly enter the North American and Australian markets.
