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

Dong Bin, deputy general manager of solar energy and commercial product services of TÜV Rheinland Greater China, and Yi Huiqiong, general manager of REPT BATTERO Energy Storage Market, attended the certification ceremony and reached further willingness to cooperate on subsequent product functional safety certification. As a professional third-party certification agency in the field of energy storage batteries and systems, TÜV Rheinland has conducted comprehensive safety inspections on the Ruipula Lanjun Energy Y52 liquid-cooled battery cluster from the cell, module, unit and installation levels to provide energy storage system Applications. Safer guarantee helps products enhance global competitiveness.

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

UL 9540A

As 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, UL 9540A is an important way to verify the safety of energy storage products. It has been approved by the U.S. National Fire Protection Agency and federal judicial agencies. And recognition by major energy storage associations in various regions around the world has become an indispensable passport to enter the North American market and even the global market.

TÜV mark

TÜV Mark stands for TÜV Bauart Mark. TÜV Mark is a German safety certification mark for electrical appliances and parts. It has a very high degree of recognition in the EU market.

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

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

cTÜVus

cTÜVus certification is an authoritative certification mark that products comply with relevant laws and regulations in North America. Having TÜV Rheinland's cTÜVus certification mark can prove that the Y52 liquid-cooled battery cluster complies with relevant safety standards in 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. It is also a dual-nationally recognized standard for American ANSI and Canadian SCC. In addition, this standard is also recognized by other regions, such as the Australian CEC. Products that obtain this certificate can successfully enter the North American and Australian markets.
