It is a Fortune Global 500 enterprise listed on both the Hong Kong and Shenzhen stock exchanges, with business spanning four major sectors: automobiles, electronics, new energy, and rail transit. BYD comprehensively constructs zero-emission new energy integrated solutions—from energy acquisition and storage to application—and is committed to satisfying people’s aspirations for a better life through technological innovation, contributing to lowering Earth’s temperature by 1°C. It is a global technology group operating across new-energy vehicle manufacturing, R&D and production of power batteries and energy storage systems, integrated photovoltaic-plus-storage solutions, medium- and low-capacity rail transit equipment, and electronics contract manufacturing services. In 2025, its new-energy vehicle sales reached 2.426 million units; overseas revenue amounted to RMB 4.873 billion, accounting for 18.6% of total revenue. Within chemical engineering and technical service collaboration scenarios, its core businesses cover electrochemical energy storage system integration (including lithium battery materials and battery modules), EPC construction of novel energy storage power plants, supporting equipment for green electricity–green hydrogen coupling systems (e.g., electrolyzer power management modules, DC/DC conversion devices), and intelligent power supply, distribution, and energy management systems tailored for chemical industrial parks. Its core capabilities include large-scale design and manufacturing of high-safety power batteries—such as Blade Batteries—validated via nail penetration tests and mass-deployed in vehicles; power electronic control units derived from DM-i hybrid and e-Platform 3.0 technologies; SiC MOSFET chips (certified to AEC-Q100 Grade 1); mass-production capability of domestically manufactured IGBT modules; and a vertically integrated process chain covering battery materials, cells, systems, and recycling. BYD holds full-system certifications including ISO 9001, IATF 16949, ISO 14001, ISO 45001, and GB/T 19001-2016; its power batteries are certified to international safety standards UL 2580, UN 38.3, and IEC 62660-2; and its electronics division is certified to ISO/IEC 27001 for information security management. Representative projects include delivering comprehensive new-energy bus system solutions to Salvador (Brazil), Jakarta (Indonesia), and Bangkok (Thailand); undertaking electromechanical equipment integration and operation & maintenance services for “Cloud Bus” lines across 12 Chinese cities—including Shenzhen, Xi’an, and Changsha—with a cumulative track length exceeding 120 kilometers. Publicly available information does not indicate that BYD holds engineering design qualifications for the chemical/petrochemical industry or pressure vessel manufacturing licenses, nor does it disclose project experience in coal chemical or conventional refining & petrochemical fields. Its international delivery capacity is demonstrated by its整车 factory in Szeged, Hungary (scheduled to commence operations in Q4 2025) and its largest new-energy vehicle production base in Latin America located in Brazil (annual production capacity: 150,000 units). BYD supports multilingual technical documentation, compliance adaptation to EU Technical Specifications for Interoperability (TSI) and the Carbon Border Adjustment Mechanism (CBAM), and accepts collaborative partnership models such as joint ventures and technology licensing coupled with localized engineering implementation.
