Huizhou BYD Battery Co., Ltd., located in Zhongkai High-Tech Industrial Development Zone, Huizhou City, Guangdong Province, is a core manufacturing enterprise under BYD Company Limited, specializing in the research and development, production, and sales of lithium-ion batteries. It occupies a critical position within the new-energy vehicle and novel energy storage industry chain and operates at a mature, large-scale stage. The company maintains multiple large-scale production bases, including those in Zhongkai and Kengzi (both in Huizhou), and possesses end-to-end manufacturing capabilities spanning battery materials, cells, modules, and systems. Its primary business covers power batteries (including Blade Batteries), energy storage battery systems, battery modules, and PACK integration; its products are widely applied in battery electric passenger and commercial vehicles, rail transit, grid-side and user-side energy storage projects. Core competencies include proprietary technologies such as structural optimization of lithium iron phosphate (LFP) battery systems, CTB (Cell-to-Body) integrated thermal management, and high-safety Blade Battery packaging processes—over 420 invention patents have been granted to date. The company masters the “long-and-thin electrode stacking process” and “cell-to-pack (CTP) integration technology,” both listed in the Ministry of Industry and Information Technology’s “Catalogue of Key New Materials for First-Batch Application Demonstration (2024 Edition)” as advanced battery manufacturing key technologies. Its cell-level energy density reaches 160 Wh/kg, cycle life exceeds 4,000 cycles, and system pack integration efficiency stands above 65%. In terms of certifications, the company has obtained ISO 9001:2015, IATF 16949:2016, ISO 14001:2015, and ISO 45001:2018 management system certifications; it holds a “Work Safety Production License” and a “High-Tech Enterprise Certificate” (valid until December 2026); all information is verifiable on the Guangdong Provincial Department of Science and Technology’s official website and the National Certification and Accreditation Information Public Service Platform. Representative achievements include supplying Blade Batteries for BYD’s flagship models—including the Han EV, Seagull, and Yangwang U8—contributing to BYD’s 39.8% market share of installed power battery capacity for domestic new-energy passenger vehicles in 2025. In 2025, external sales of energy storage battery systems reached 12.7 GWh, with deep participation in several hundred-megawatt-scale shared energy storage power station projects undertaken by China Energy Investment Corporation and China Southern Power Grid. Regarding international operations, leveraging BYD’s overseas整车 export network, the company has supplied cells and technical standards to localized PACK factories in Thailand, Brazil, Hungary, and other countries. In 2025, cross-border technology licensing revenue amounted to RMB 180 million, supporting collaborative models including consortium partnerships and hybrid approaches combining technology licensing with engineering implementation, tailored to diverse industrial platform requirements.
