EVE Energy Unveils 6.9MWh Battery Energy Storage System and Secures Over 50GWh Strategic Contracts at ESIE 2026

EVE Energy Unveils 6.9MWh Battery Energy Storage System

BEIJING — The 14th Energy Storage International Summit and Exhibition (ESIE 2026) concluded with a strong statement from EVE Energy Co., Ltd. From April 1 to 3, the event held in Beijing saw EVE Energy unveil a full-scenario energy storage portfolio, headlined by a world-first 6.9MWh battery energy storage system (BESS), over 50GWh in strategic framework agreements, and multiple international safety certifications — cementing its leading position in the large-format battery storage segment.

With a spotlight on global debuts, authoritative safety recognitions, and concentrated signings, EVE Energy demonstrated technology-led momentum and industrial ecosystem influence throughout the exhibition.

World Premiere: 6.9MWh BESS Redefines Industry Benchmarks

EVE Energy introduced the latest addition to its Mr.Big Family series — the 6.9MWh large-scale battery storage system. Built upon the company's mature large-format battery platform, the new system expands EVE's high-capacity storage lineup and reinforces its leadership in utility-scale storage. The company highlights three core advantages: high-efficiency integration, ultra-long cycle life, and multidimensional safety.

⚡ High-efficiency integration
Standard 20-foot container design, system energy density increased by 10%.
Single-cell volumetric energy density exceeds 430Wh/L.
Optimized footprint reduces floor area by 6%, saving approximately 2.6 million RMB in initial investment per station — driving extreme cost efficiency.

🔄 Ultra-long life
Delivers 10,000 cycles @ 70% SOH, matching cell lifespan.
Intelligent 3A active balancing technology combined with precision thermal management ensures system temperature difference ≤5°C, guaranteeing stable operation throughout lifecycle.

🛡️ Multidimensional safety
1500V DC full-voltage 5-level graded protection architecture.
Innovative “AI + composite detection + staged fire suppression” solution — covering early warning, intervention, and long-term suppression for complete fire protection loop.

Over 50GWh in Strategic Agreements: Building Industry Ecosystem with Partners

During the exhibition, EVE Energy signed centralized strategic cooperation agreements with five industry frontrunners: Goldwind Zero Carbon, JinkoSolar Energy Storage, Linyang Energy, CEEC Energy Storage Technology, and Ronghe Yuanchu Energy Storage. The partnerships focus on large-format battery storage and core products, with cumulative contracted volume exceeding 50GWh. The real-order backlog reflects strong market validation and customer recognition for EVE's energy storage solutions.

📍 Signed partners at ESIE 2026: Goldwind Zero Carbon, JinkoSolar Energy Storage, Linyang Energy, CEEC Energy Storage Technology, Ronghe Yuanchu Energy Storage — total framework volume surpasses 50GWh.

Global Certifications Reinforce Product Excellence & Safety

Safety remains the fundamental pillar for energy storage systems. EVE Energy has consistently adopted rigorous standards to validate product safety. At the show, CSA Group presented EVE Energy with the large-scale fire test certificate for its 628Ah large-format battery-based 5MWh BESS. This certification once again demonstrates EVE's profound expertise in large-capacity system safety design and sets a practical benchmark for industry safety technology upgrades.

The fire test was conducted strictly in accordance with CSA/ANSI C800:25, UL 9540A, and NFPA 855 international standards, comprehensively verifying fire safety and thermal runaway prevention capabilities for large-scale systems. Mr. Wu Wei, Commercial Director of CSA Group China's Industrial and New Energy Division, presented the certificate on-site, which was received by Mr. Zhao Zihui, Director of the Power Energy Storage System Technology Center at EVE Energy's Energy Storage Research Institute.

✅ Additional certifications: EVE Energy’s 261kWh outdoor all-in-one energy storage cabinet obtained SGS CB/CE/AS triple certification, while the S6900 storage system earned SGS CB/CE certifications — accelerating global compliance and strengthening international market expansion.

From technology breakthroughs with the world debut of 6.9MWh BESS, to international authority endorsements, and market validation with over 50GWh in signed orders — every move by EVE Energy at ESIE 2026 underscores its deep cultivation and accumulated expertise in the large-format battery storage arena. Looking ahead, EVE Energy remains committed to long-term value creation, continuously advancing core large-capacity storage technologies, and collaborating with global partners to foster a new energy storage ecosystem while injecting sustainable momentum into the global green energy transition.
