Group 1: Product Features - The Chess Plus cabinet utilizes energy storage-specific thick blade cells (320Ah) with a cycle life exceeding 10,000 times and a Pack-level IP65 protection rating, achieving system efficiency of up to 90% [2]. - The product features a unique full-tab design for more uniform current distribution and heat dissipation, preventing localized overheating, and includes a comprehensive thermal safety system with built-in aerosol fire extinguishing and high-pressure liquid cooling pipelines [2][3]. Group 2: Economic Model - BYD proposes a "rapid return" closed-loop model to address the long payback period (over 5 years) and policy fluctuation risks (electricity price adjustment cycles of 2-3 years) faced by commercial energy storage projects [2]. - The intelligent liquid cooling system maintains a temperature difference of ≤2.5℃, extending battery life by 30% and reducing energy consumption by 20%, significantly improving the investment return rate for commercial energy storage projects [2]. Group 3: Scene Adaptability - The new product features an ALL in One minimalist high-integration design, reducing system components by 55.6%, and allows for flexible modular expansion to lower initial investment costs [3]. - It simplifies installation processes, making it suitable for various spatial constraints in urban commercial areas and open industrial parks, and includes an intelligent operation and maintenance system adaptable to multiple operational modes [3]. Group 4: Strategic Goals - BYD's energy storage business has established a full-chain layout from cells to systems to global projects, with a goal to achieve the largest market share in the global energy storage market by 2024 [3][5]. - The company has highlighted two key R&D projects in its 2024 report: the Cube Energy Storage System and the Liquid Cooling Medium Voltage Cascade Energy Storage System, with the latter being shipped to the Southern Power Grid as part of the first domestic liquid-cooled cascade energy storage demonstration project [3].
