EVE Energy Launches First Series-Produced 628Ah Battery Cells

In the rapidly evolving energy storage industry, EVE Energy has emerged as a pioneering force by achieving a significant milestone—mass production of battery cells with a capacity surpassing 600Ah, specifically 628Ah.

On December 10, 2024, the company inaugurated its first phase of the 60GWh Super Energy Storage Factory located in Jingmen, Hubei Province. This facility signifies not just a technological advancement but a strategic positioning in the industry, showcasing EVE Energy's commitment to meeting the increasing global demand for high-capacity battery solutions.

With the energy storage market gradually adopting cells of 300Ah capacity, mainly around 314Ah, the move towards larger capacity cells is a testament to the industry's shift. EVE Energy had already begun its journey by producing 560Ah cells back in 2022 while competitors were still focused on the lower capacity. The ongoing advancements reflect a strong understanding of market dynamics and foresight.

The Technological Leap Forward

EVE Energy's newly released 628Ah cells bring many benefits, including reduced costs and complexity in energy storage system integration, enhanced energy density, and improved safety measures. The process of scaling up capacity allows for a streamlined manufacturing process that reduces the number of components needed, leading to a more efficient assembly process.

However, challenges like thermal regulation and the overall performance of high-capacity cells persist. To troubleshoot these issues, EVE Energy has teamed up with Yang Hanxi, a professor from Wuhan University, to develop an electrochemical collection model based on advanced scientific principles. This enhanced design optimizes the collection medium's thickness, contact placement, and terminal geometry, ensuring a high-speed pathway for electrons. The result is a notable reduction in internal resistance, which mitigates heat generation risks.

To bolster safety and reliability, the firm unveiled its intelligent battery technology during the factory launch. This innovation utilizes high-precision real-time monitoring throughout the battery life cycle, akin to how smartwatches track vital health statistics. It enables the monitoring of gases, temperatures, and other critical data, ensuring prompt detection of any anomalies to allow for timely alerts and protective actions.

Introducing the 60GWh Super Energy Storage Factory

The opening of EVE Energy's state-of-the-art 60GWh factory emphasizes the company's drive to scale up the production of its Mr. Big battery cells. This super factory employs over 80 cutting-edge industry technologies to ensure fully automated processes throughout manufacturing stages. The factory operates at an astonishing rate, achieving the production of 1.5 battery cells every second, which translates to the assembly of four complete battery packs every minute. In a single day, it can generate more than 40 containers, each containing 5MWh of capacity.

To illustrate the sheer capacity of this production, a total of 1GWh of batteries produced could meet the annual energy needs of about 300,000 households based on 300 charging and discharging cycles per year. EVE Energy's strategic location in Jingmen has further facilitated the enhancement of supply chain logistics, significantly optimizing costs associated with logistics and storage, which ultimately improves operational effectiveness.

Unmatched Quality Management

Quality management remains paramount in EVE Energy's operations, achieving fault rates at the level of units per billion (PPB). The company has established rigorous cleanliness protocols alongside advanced technologies, ensuring compliance with stringent industry standards. The factory's quality management system integrates several cutting-edge technologies, including image databases and artificial intelligence, to promote a closed-loop quality control approach. Each battery unit is also provided with a data package and unique battery passport for complete life cycle tracking.

With this significant launch, EVE Energy has positioned itself as the first company to mass-produce battery cells exceeding 600Ah capacity, signifying a momentous step forward in the energy storage sector. The company's foresight and groundbreaking advancements are set to contribute substantially to the global energy transition and sustainable development.
