In a significant move to meet the escalating demand in the burgeoning era of large-scale energy storage, CORNEX New Energy proudly announces the commencement of mass production for its revolutionary CORNEX M5, a 20-foot 5MWh battery energy storage container. This milestone was achieved on February 1st at the state-of-the-art CORNEX Xiaogan Plant.
Dedicated to staying at the forefront of the “big storage era,” CORNEX New Energy leverages its proprietary technology to cater to diversified energy storage applications. By emphasizing self-researched innovations, the company establishes comprehensive system advantages, offering top-tier “CORNEX solutions” for global new energy applications.
The CORNEX M5 represents a breakthrough in energy storage technology, boasting five key advantages that collectively achieve an unparalleled balance of enhanced performance, reduced costs, heightened safety, improved efficiency, and broader applicability.
1. Enhanced Capacity
The CORNEX M5 features a groundbreaking Juneng Ï€ 314Ah energy storage battery cell, developed in-house. With a cycle life of up to 12,000 cycles and an impressive energy density of up to 185Wh/kg, this innovation has propelled the container’s energy storage capacity to an impressive 5MWh. This translates to a remarkable 49% increase in system volume energy within the same 20-foot footprint. The design incorporates dynamic power allocation based on battery characteristics and multi-stage variable-diameter and balanced liquid-cooling piping, enhancing the system’s cycle life by 20%.
2. Cost Efficiency
Implementing a streamlined single-door design, the CORNEX M5 reduces space requirements by 32%, resulting in a 10% decrease in comprehensive operating costs. This design achieves an optimal balance between capacity and space costs within the standard 20-foot energy storage system footprint.
3. Safety First
The CORNEX M5 prioritizes safety with a unique design, featuring the proprietary “Submerge” battery safety system and module-level fire protection. This system ensures precise fire extinguishing within 3 minutes, preventing heat spread from the electric cell to the module and pack. Adhering to the industry’s strictest standards, such as GB/T 36276, IEC 62619, UL9540A, the “Submerge” design guarantees the safety and stability of the system throughout its lifecycle.
4. Efficiency Unleashed
Equipped with intelligent cluster-level management technology, the CORNEX M5 maximizes efficiency by managing each cluster individually, eliminating inter-cluster circulation. The system also incorporates a new generation high-efficiency liquid-cooling temperature control system, ensuring a controlled temperature difference within the pack. With a cloud-based health management system, energy efficiency management strategies are dynamically adjusted, ensuring minimal operation, high efficiency, and safety.
The CORNEX M5 is designed for versatile applications, featuring IP55 level protection for the entire machine and IP67 level for the battery pack. Operating in temperatures ranging from -30°C to 60°C, this container ensures safety and stability even in extreme environments. Supporting various system combinations of centralized and string PCS, the CORNEX M5 adapts swiftly to evolving PCS technology requirements.
In response to the global “carbon peaking and carbon neutrality” initiative, CORNEX New Energy strategically establishes production bases, exceeding an effective production capacity of 100GWh. The CORNEX M5-20′ 5MWh battery energy storage container upholds the company’s guiding principle of “Think More,” committed to delivering optimal solutions from design to after-sales service. With a focus on enhanced performance, reduced costs, heightened safety, improved efficiency, and broader applicability, CORNEX New Energy aims to provide unparalleled energy storage solutions to customers globally.
