NXP Semiconductors N.V. has unveiled its new, industry-first wireless battery management system (BMS) solution with Ultra-Wideband (UWB) capabilities from one of the industry’s broadest UWB portfolios. The new UWB BMS solution marks the next step in overcoming development challenges including costly and complex manufacturing processes, accelerating the adoption of electric vehicles (EVs).
NXP’s UWB wireless BMS technology decouples mechanical and electrical development, offering EV manufacturers increased flexibility, faster time to market and reduced development costs – while maintaining full scalability of the system across different platforms.
Leveraging wireless solutions minimizes the use of complex wiring harnesses in the battery pack, and reduces the need for error-prone manual effort during production, which makes the assembly of EVs more efficient and reduces overall lifecycle costs. The elimination of connectors and wiring between battery cells allows for increased energy density, which is a key parameter in EV design and performance to enable longer range.
“Our wireless battery management system solution is the industry’s first to include UWB technology, offering EV manufacturers the most advanced technology to power tomorrow’s electric vehicles,” explains Naomi Smit, GM & VP Battery Management Systems at NXP. “Trimension UWB delivers simple, safe, and robust wireless communication within the BMS, outperforming existing narrow-band based solutions. We are proud to work with our customers to make the wireless promise reality.”
NXP’s Ultra-Wideband wireless battery management system solution is available for OEMs to start evaluation and development in Q2 2025.
The solution is part of NXP’s FlexCom chipset which supports wired and wireless technologies, providing OEMs and Tier-1-suppliers with greater flexibility in vehicle architecture and technology choices. Its common software architecture and safety libraries for both BMS configurations enables them to reuse software across different platforms, further reducing development efforts.
NXP’s MC33777 battery junction box IC: The NXP FlexCom BMS chipset also includes NXP’s recently announced MC33777 Battery Junction Box (BJB) IC, serving high voltage systems with accurate voltage, chassis isolation and current measurements. The BJB is part of NXP’s complete turnkey battery management system offering and can be used with wired and wireless battery management solutions, alongside NXP’s software and applications, without the need for manufacturers to enlist additional partners.
NXP’s Electrification Solutions: NXP’s Electrification solutions manage the flow of energy across the electrified ecosystem including electric vehicles, homes and buildings, and smart grids. In EVs, flexibility and precision enable our customers to extend driving range and keep vehicles on the road longer. With complete system solutions for EVs, including battery cell controllers, battery junction box, communication gateway and microcontroller, NXP’s electrification solutions deliver the optimized performance and integrated safety that OEMs need.
