Leveraging over two decades of deep technical expertise, Bafang stands among the few global enterprises possessing full-chain, one-stop capabilities for complete interconnected eBike systems R&D and production. This integrated approach ensures deep synergy between critical components, including motors, displays, batteries, controllers, sensors and other components. It powers Bafang’s diverse product portfolio, such as the H730 3-speed automatic shifting hub system and M430 cargo mid-drive system.
These advanced systems are underpinned by battery technology engineered for exceptional reliability, safety, and environmental responsibility. While meeting stringent new EU standards like EN 50604-1 and Regulation 2023/1542 demonstrates Bafang's fundamental commitment to European safety expectations and consumer trust, the true focus lies in how these batteries achieve superior performance through advanced design, rigorous testing, precise manufacturing, and sustainable practices.
Advanced design
- Automotive-grade BMS management: Bafang's battery development leverages lessons from the demanding automotive industry. Featuring multi-protection designs, Bafang's automotive-grade Battery Management Systems (BMS) provide millisecond-level communication and monitor critical parameters (voltage, current, temperature) throughout the battery's entire lifecycle.
- Optimized Cell Performance: Proprietary cell activating technology combined with intelligent trickle charging solutions ensures each cell operates at its potential. This synergy maximizes energy utilization and significantly extends the overall battery cycle life.
- Secure Charging Ecosystem: Chargers incorporate multi-control safety designs and maintain real-time communication with the battery, guaranteeing a secure and highly efficient charging process.
- Advanced Sealing Solutions: Employing high-temperature resistant, flexible sealing materials combined with precision laser welding techniques, Bafang ensures a hermetic seal. This prevents water ingress, a critical factor in long-term reliability and safety, enabling batteries to perform optimally even in harsh conditions.
