Recently, Rept Battero Wending 320Ah energy storage cells have passed the three international authoritative certifications of UL 1973, UL 9540A, and IEC 62619: 2022 issued by TÜV Rheinland, Germany, which marks the safety performance of Wending 320Ah energy storage cells. It has reached international standards and obtained a pass to the international market.

Wending 320Ah energy storage cell is a new generation product of Rept Battero energy storage series, which integrates multiple core technologies such as cell structure technology, process technology and equipment technology innovation, and stable solid-liquid interface.

Relying on the top technology independently developed by Rept Battero, the top 320Ah energy storage cell has the same size as the 280Ah square cell, and realizes the superior performance of high energy, long life, and high safety. The volumetric energy density of the product reaches 400Wh /L, the cycle life is 8000-10000 times, and the calendar life is more than 20 years. This year, Q3 has mass production capacity, becoming the pioneer in the industry to achieve mass production of 320Ah batteries.

 UL 1973

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.

UL9540A

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, is an important way to verify the safety of energy storage products. It has become an indispensable pass to enter the North American market and even the global market.

IEC 62619

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