The 2025 International Digital Energy Expo commenced today in Shenzhen, drawing industry leaders, experts, and professionals from around the world. Centered on the theme "Cleaner Energy Generation, Smarter Grids, Flexible Demand, and Diversified Storage," attendees delved into collaborative development strategies and collectively envisioned a new digital energy ecosystem. During the grand opening ceremony, all eyes were on BYD Energy Storage as it unveiled its groundbreaking energy storage product—Haohan—in a highly anticipated global debut.

The ceremony was graced by the presence of key BYD executives: He Long, Executive Vice President of BYD Group and CEO of the Battery Business Group; Zhao Tong, Deputy General Manager of the Second Division and TBO Director; and Yin Xueqin, General Manager of the Energy Storage and New Battery Division. Cao Hu, Dean of the Power Science Research Institute within the Energy Storage and New Battery Division, took the stage to share the inspiring journey of Haohan—from its initial concept to final realization—offering deep insights into the advanced technology and thoughtful design philosophy behind the product.

Haohan is powered by the world's largest 2710Ah blade battery, specifically tailored for energy storage applications. This innovation delivers over three times the capacity of conventional storage batteries, marking a monumental leap in energy density. With a minimum unit capacity of 14.5MWh, it leads the global rankings. Packed into a standard 20-foot container, Haohan achieves an ultra-high capacity of 10MWh, accompanied by a remarkable Vcts of 52.1%—the highest in the world and 39.7% above the industry average. By requiring fewer containers, reducing spatial footprint, and simplifying management architecture, Haohan elevates system integration to a whole new level, perfectly living up to its motto: "small in size, big in energy."

Moreover, Haohan boasts the world’s highest system protection rating—IP66. It provides complete dust resistance and performs exceptionally even in sandstorms and other harsh environments. This superior protection doubles the service life of dust-sensitive components, reduces system failure rates by 70%, and slashes maintenance costs by 70%, setting an unparalleled benchmark for all-scenario energy storage applications.

According to Cao Hu, Haohan was developed under the guiding principle that "greatness lies in simplicity." Integrating ultra-safety, high efficiency, and an extended service life, it offers robust support for the upcoming TWh-scale power station era. Haohan is poised to empower grid upgrades and propel the energy storage industry toward a greener, smarter, and more sustainable future.

At the expo, BYD Energy Storage also showcased its self-developed PCS all-in-one machine, the GC Flux, and the EMS energy management system, GC Master, alongside Haohan—presenting global users with GW-level grid-forming energy storage solutions. Leveraging the advantage of "full-stack in-house R&D, from cell to grid," the system achieves end-to-end optimized efficiency, fully meeting the demands of storage stations that function as both power and energy hubs. This significantly enhances grid resilience and paves the way for a more flexible, robust, and intelligent energy future. The display attracted large crowds of visitors who stopped to observe, discuss, and exchange ideas—making Haohan the undeniable star of the event.

At this year’s expo, BYD Energy Storage reaffirmed its commitment to building an open and comprehensive energy ecosystem, injecting powerful "Shenzhen power" into national energy security, industrial transformation, and green, low-carbon development. Guided by the principle of "technology as the core, innovation as the foundation," BYD Energy Storage will continue to advance in the field of clean energy, delivering more cutting-edge and reliable products and solutions. Together with global partners, the company is determined to explore the future of digital energy and jointly build a new era of smart, sustainable energy.
