NXP Semiconductors has introduced the automotive industry’s first wireless battery management system (BMS) incorporating Ultra-Wideband (UWB) technology, marking a significant advancement in electric vehicle (EV) development. This innovative system, part of NXP’s FlexCom chipset portfolio, enables seamless communication within battery packs, supporting both wired and wireless BMS configurations through a unified software platform. By eliminating traditional wiring between battery cells, the UWB BMS not only streamlines EV assembly but also enhances energy density, contributing to longer driving ranges and improved overall performance. The decoupling of mechanical and electrical components allows manufacturers greater flexibility and accelerates time-to-market while reducing costs.
One of the standout features of NXP’s UWB solution is its resilience against reflective and frequency-selective fading environments, outperforming conventional narrow-band systems like Bluetooth Low Energy (BLE). The technology’s use of high-bandwidth pulses ensures robust data transfer and more reliable battery monitoring. This system aligns with NXP’s commitment to integrated electrification solutions that manage energy across various systems, promoting efficiency and extended EV operation. NXP’s comprehensive BMS solution also includes the MC33777 Battery Junction Box IC for precise voltage and current measurements, enhancing high-voltage system management. The new UWB wireless BMS will be available for evaluation by OEMs in 2025, highlighting NXP’s role in driving forward innovation and sustainability in the EV sector.
