SEVB (Sunwoda Mobility Energy Technology) designs and manufactures lithium-ion cells, modules, BMS and packs for EVs and energy storage. The company emphasizes ultra-fast charging (up to 12C), extended cycle life, safety features, and OEM co-development.
SEVB (Sunwoda Mobility Energy Technology Co., Ltd.) is a global new-energy technology company originating from Sunwoda, which has nearly 30 years of industry experience. Headquartered in Shenzhen, Guangdong, China, SEVB focuses on lithium-ion cell design and manufacturing, modules, battery management systems (BMS), and pack solutions for electric vehicles and energy storage. The company serves major automotive customers through OEM/ODM partnerships and integrated R&D-to-manufacturing capabilities. SEVB’s stated vision is to build an ecological platform for the new energy industry and advance competitive, scenario-based power battery and energy storage solutions.
SEVB develops lithium-ion chemistries and cell architectures optimized for high-rate charging, long cycle life, and safety. Key features include ultra-fast charging platforms (Flash Charging 4.0 up to 12C), thermal-electrical separation, inverted bottom venting, and multi-layer protection. The company pairs cell designs with proprietary BMS and pack engineering to manage high currents, temperature control, and cell balancing. SEVB also offers modular platforms for different vehicle segments and large-format cells for energy storage, delivering higher energy density (reported up to ~180–190 Wh/kg in some formats) and extended cycle life for grid applications.
SEVB’s product portfolio includes lithium-ion cells, modules, full battery packs with integrated BMS, and containerized energy storage systems. Key benefits are ultra-fast charging capability, long cycle life, improved low-temperature performance, and multi-level safety features. Products are targeted at BEVs, PHEVs/HEVs, energy storage systems (ESS) for grid and renewables, as well as consumer and specialty applications such as marine and aviation batteries.
In September 2025 SEVB and Li Auto formed a 50:50 joint venture to co-develop and manufacture batteries tailored to Li Auto’s ultra-fast-charging vehicle platforms (models referenced as L6, L7 Air, L8 Air). The agreement builds local manufacturing capacity and aligns cell and pack design to Li Auto’s fast-charge requirements, aiming to improve supply resilience and optimize cost and performance for the OEM’s product lineup.
SEVB operates as a mobility energy subsidiary of Sunwoda. In 2022 Li Auto invested RMB 400 million for a 3.22% stake in SEVB’s EV battery unit. Strategic cooperation has progressed into a 50:50 manufacturing joint venture with Li Auto (September 2025) focused on co-developed batteries for Li Auto vehicle platforms.
