Wireless Battery-Management System Untangles EV Batteries

Texas Instruments showcased a wireless battery-management system (wBMS) at CES, aiming to simplify the complex wiring in EV battery packs. By replacing heavy cabling with wireless connections, wBMS can increase EV range and reduce development costs. The system allows for real-time monitoring of cell voltages, currents, and temperatures to prevent faults. Texas Instruments uses a proprietary protocol for reliable wireless connections, addressing challenges like RF link budget and interference. The wireless BMS is scalable and can support second-life EV batteries, offering high throughput and low latency.
