On September 18, 2025, the 2025 International Digital Energy Exhibition opened in Shenzhen. Leading companies, experts, scholars, and industry elites in the global energy field gather together to jointly plan a new digital energy ecosystem around the collaborative development path of "source side cleanliness, grid side intelligence, load side flexibility, and storage side diversification". BYD Energy Storage launched its new energy storage product "Haohan" at the opening ceremony of the exhibition, attracting much attention.

BYD Group's Executive Vice President and CEO of the Battery Business Group, He Long, Deputy General Manager and TBO Director of the Second Business Unit, Zhao Tong, and General Manager of the Energy Storage and New Battery Business Unit, Yin Xueqin, attended the opening ceremony of the exhibition. Cao Hu, President of the Electric Power Science Research Institute of the Energy Storage and New Battery Division, shared his vast "past and present" and deeply interpreted the leading technology and design philosophy carried by BYD's vast energy storage business.

BYD Energy Storage Haohan is equipped with the world's largest 2710Ah energy storage dedicated blade battery, which has a capacity increase of over 300% compared to conventional energy storage batteries, achieving a breakthrough in energy density. The smallest unit capacity of Haohan reaches 14.5MWh, setting the record for the world's largest. Within an equivalent 20 foot container, Haohan has achieved a super large capacity of 10MWh, with Vcts reaching the world's highest 52.1%, an increase of 39.7% compared to the industry. With fewer containers, smaller footprint, and simplified management architecture, Haohan has pushed the system integration to a new height, truly achieving "small volume, large energy".

Haohan also has the world's highest overall protection level - IP66, achieving complete dust prevention, no fear of wind and sand, and can easily cope with various extreme environments. It increases the service life of dust sensitive devices by 100%, reduces system failure rates by 70%, and reduces maintenance costs by 70%, redefining a new standard for energy storage applications in all scenarios.

Cao Hu stated that BYD Energy Storage Haohan adheres to the research and development philosophy of "simplifying the road", integrating ultra safety, high energy efficiency, and long lifespan, providing strong support for the arrival of the TWh level power station era, comprehensively assisting in the upgrading of the power grid, and promoting the new energy storage industry towards green, intelligent, and high-quality sustainable development.

At the exhibition, BYD Energy Storage, equipped with BYD's self-developed PCS integrated machine GC Flux and EMS energy management system GC Master, provided a GW level grid based energy storage solution for global users. With the leading advantage of "core to grid, full stack self-developed", the system achieved the best overall efficiency, fully meeting the strong support and full load power demand of energy storage stations as power and electricity hubs, effectively empowering the resilience of the power grid, and helping to build a more flexible, robust, and intelligent future of the power grid. It attracted many visitors to stop and watch, discuss and exchange ideas, and became the strongest "popular king" of the entire exhibition.

At this exhibition, BYD Energy Storage is committed to building a comprehensive and open energy ecosystem, injecting strong "Shenzhen power" into national energy security, industrial transformation, and green and low-carbon development. BYD Energy Storage will continue to uphold the development concept of "technology is king, innovation is the foundation", deepen the layout of the clean energy track, explore the new future of digital energy with global partners with more leading and reliable energy storage products and solutions, and jointly build a new era of green and smart energy.
