On 18th, Renesas Electronics Corporation, a global leader in semiconductor solutions, has launched the Ready Battery Management System with Fixed Firmware (R-BMS F) to simplify the development of lithium-ion battery packs. Designed for e-bikes, vacuum cleaners, robotics, and drones, this all-in-one system integrates pre-validated firmware, fuel gauge ICs (FGICs), a microcontroller (MCU), and a battery front-end to streamline battery management design.
By offering pre-programmed firmware, Renesas eliminates the complex development process, enabling manufacturers to reduce time-to-market and ensure safer, longer-lasting, and more energy-efficient battery systems. The R-BMS F system supports both 2-4 cell (8V to 16V) and 3-10 cell (12V to 40V) lithium-ion batteries, making it a versatile solution for a wide range of consumer and industrial applications.
Pre-Programmed Firmware: Enhancing Safety and Efficiency
Firmware plays a critical role in modern battery management systems by monitoring state of charge (SoC), state of health (SoH), voltage, current, and temperature, while actively balancing the battery’s cells. The R-BMS F solution includes pre-tested firmware, eliminating the need for manufacturers to develop complex control algorithms. Additionally, manufacturers can adjust settings via a graphical user interface (GUI) without requiring extensive programming expertise or an integrated development environment (IDE).
“Not everyone has the expertise or in-house resources to write their own algorithms. Our all-in-one R-BMS F battery management system eliminates this process and provides market-ready power solutions that work without requiring specialized technical knowledge of MCU programming or advanced battery management design.” said Chris Allexandre, Senior Vice President and General Manager of Power at Renesas.
All-Inclusive Evaluation Kits for Streamlined Development
To further support developers, Renesas provides fully integrated evaluation kits that include all necessary hardware, software, and documentation for rapid prototyping and deployment. The system features:
- Fuel Gauge ICs (FGICs) that combine an analog battery front-end with an ultra-low-power RL78 MCU, enabling accurate voltage, current, and temperature measurements.
- Embedded firmware stored in flash memory, with flexible parameter configuration for different battery chemistries.
- USB System Management Bus (SMBus) interface, ensuring seamless integration with existing devices.
- GUI-based software, allowing users to customize battery settings without deep technical expertise.
These comprehensive evaluation kits are now available, providing developers with a low-risk, optimized design that reduces development time and accelerates market entry for battery-powered devices.
Two Distinct Configurations for Maximum Compatibility
Renesas offers two battery management solutions tailored to different device applications:
- 2-4 Cell Series Solution (RTK0EF0163DK0002BU): Ideal for robotic vacuums, medical devices, and small consumer electronics, this version is built around the Renesas RAJ240055 Li-ion battery FGIC.
- 3-10 Cell Series Solution (RTK0EF0136DK0002BU): Designed for e-mobility solutions, drones, industrial systems, and high-performance consumer electronics, utilizing the Renesas RAJ240100 and RAJ240090 Li-ion battery FGICs.
Both configurations leverage Renesas’ Winning Combinations—pre-vetted system architectures that integrate mutually compatible components for optimized performance and minimal design risk.
Conclusion
Renesas continues to push the boundaries of battery management technology, ensuring higher safety standards, improved efficiency, and reduced environmental impact. As the demand for energy-efficient solutions grows, the R-BMS F platform provides an innovative approach to battery monitoring, fault detection, and lifecycle management. With its pre-integrated firmware, evaluation kits, and GUI-based customization tools, the Renesas R-BMS F system is set to revolutionize battery management across multiple industries.
