On January 21, CRRC Zhuzhou Electric Locomotive Institute Co., Ltd. and Great Power officially launched the 688Ah WindPeng battery cell, signaling the entry of the energy storage industry into the "Dual-Six Era," where single-cell capacity exceeds 600Ah and system energy surpasses 6MWh. The milestone event was celebrated with a visit from a delegation led by Tang Yuanyuan, Party Secretary and General Manager of CRRC Zhuzhou Electric Locomotive Institute's Integrated Energy Business Division, alongside Xia Xinde, Chairman of Great Power.
Amid the global transformation of energy structures and the rapid development of new power systems, the energy storage market is experiencing rapid growth. As the backbone of energy storage systems, battery cell technology is advancing quickly in both capacity and efficiency. CRRC Zhuzhou Electric Locomotive Institute Co., Ltd., a global leader in energy storage system integration, has teamed up with Great Power, a company with 24 years of battery technology expertise, to jointly develop the 688Ah ultra-large-capacity battery cell, establishing a new industry benchmark.
The development of the WindPeng 688Ah battery cell embodies the technical strengths and innovative achievements of both parties:
Ultra-High Cycle Life: Leveraging Great Power's 10,000-cycle platform technology, the battery cell achieves a cycle life of over 10,000 cycles and a calendar life exceeding 20 years, providing customers with full lifecycle value assurance.
Exceptional Energy Efficiency: Through the ion sponge platform technology, the cell's energy efficiency exceeds 96%, positioning it as an industry leader.
Ultimate Safety Assurance: Equipped with cutting-edge safety platform technology, the cell ensures intrinsic safety at the fundamental level, guaranteeing stable operation under extreme conditions.
The WindPeng 688Ah battery cell not only achieves breakthroughs in performance but also significantly simplifies the complexity of energy storage system integration:
Increased System Capacity: When paired with the 688Ah battery cell, the energy storage system capacity can be increased to 6.9MWh, enabling more precise energy configuration.
Cost Optimization: By reducing the number of components and integration costs, the initial investment and lifecycle costs of energy storage power plants are significantly lowered, delivering higher economic benefits to customers.
After the launch ceremony, the CRRC Zhuzhou Electric Locomotive Institute Co., Ltd. delegation, along with Chairman Xia Xinde, toured Great Power’s exhibition hall and engaged in detailed strategic discussions. Both parties praised the technical achievements of their collaboration and explored potential future cooperation in the global energy storage market for 2025. Going forward, CRRC Zhuzhou Electric Locomotive Institute Co., Ltd. and Great Power will combine their strengths to expedite the market introduction of the WindPeng 688Ah battery cell and drive its widespread use in demonstration energy storage projects.
The official launch of the WindPeng 688Ah battery cell marks the energy storage industry’s entry into the "Dual-Six Era." The powerful collaboration between CRRC Zhuzhou Electric Locomotive Institute Co., Ltd. and Great Power has brought groundbreaking changes to the global energy storage market, driving significant momentum for the industry's high-quality development. Moving forward, the two companies will continue their partnership to accelerate the green and low-carbon transformation of the global energy structure, making a vital contribution to achieving carbon neutrality goals.
