[SMM Analysis] REPT Battero and Hyosung Heavy Industries Reach Strategic Cooperation on 2.5 Gwh ESS

On May 27, 2025, REPT Battero Energy Co., Ltd. (hereinafter referred to as "REPT Battero") and Hyosung Heavy Industries (hereinafter referred to as "Hyosung") officially signed a Memorandum of Understanding (MoU) for strategic cooperation, marking the beginning of in-depth collaboration in the energy storage system (ESS) sector. This partnership focuses on key areas such as ESS cell supply, system integration, and market promotion.

According to the agreement signed by both parties, REPT Battero will provide Hyosung with up to 2.5GWh of ESS cells, modules, and DC-side containers. Additionally, REPT Battero will share its advanced technologies and rich experience in system design integration and quality control. Hyosung, leveraging its extensive channel network in the global power equipment market, will be responsible for product localization adaptation, certification, and promotion, facilitating the global application of the collaborative outcomes.

The core product supplied by REPT Battero in this collaboration is its new-generation 392Ah ESS cell. This cell boasts outstanding performance metrics, with an energy density of up to 415Wh/L and a cycle life exceeding 12,000 cycles. Furthermore, the cell has successfully passed the GB 44240-2024 shallow puncture test, demonstrating high safety by remaining fire- and explosion-free under thermal runaway conditions. This enables it to easily withstand extreme climatic conditions and high-load application scenarios.

The jointly developed Powtrix™ DC-side containerized ESS by both parties has also garnered significant attention. With a capacity of 6.26MWh, the system innovatively incorporates AI-powered intelligent operation and maintenance (O&M) and active balancing technologies. In practical applications, the Powtrix™ system can significantly reduce downtime by 20% while increasing battery utilization by 15%, showcasing exceptional performance and reliability. The system also offers flexible configuration capabilities, allowing easy adjustment to a 4-hour long-duration energy storage (LDES) or a 2-hour rapid-response version to meet the diverse needs of customers.

Hyosung Heavy Industries possesses profound technical expertise and rich experience in high-energy-consuming industries such as power and steel. Leveraging its professional integration capabilities in KTL certification in South Korea, as well as UL and IEC standards in Europe and the United States, Hyosung Heavy Industries will expedite the entry of collaborative products into high-growth-potential markets such as Southeast Asia and North America, significantly shortening project implementation cycles.

In addition to this collaboration with Hyosung in the South Korean market, REPT Battero's production site in Indonesia, with an annual capacity of 8GWh, will also commence operations in 2025, primarily meeting the demand for new energy heavy-duty trucks and grid-side ESS in the Southeast Asian region. Furthermore, REPT Battero's subsidiary established in Europe (located in Munich, Germany) has forged close partnerships with internationally renowned automakers such as Stellantis and Volvo. In 2024, REPT Battero's overseas revenue soared by 526.65% YoY, demonstrating strong market expansion capabilities and international competitiveness.
