TI BMS Solutions for High & Low Voltage Battery Energy Storage

Texas Instruments provides comprehensive BMS solutions for high and low voltage battery energy storage systems, including home, industrial/commercial, and grid-side applications. The document covers system architectures for both high voltage (up to 1500V) and low voltage (e.g., 48V) BMS, emphasizing improved battery data accuracy, high-voltage isolation, active cell balancing, thermal management, and wireless battery management. Key reference designs include TIDA-010279 (52s BMU), TIDA-010253 (BCU), and TIDA-010272 (HMU). The BQ78706 AFE supports up to 52 cells with ±2.4mV voltage accuracy, 300mA balancing current, 11 temperature channels, and daisy chain communication. Features include low quiescent current, high balancing current, stackable architecture, and compliance with IEC60730 and UL 1973. The solutions integrate CAN, RS-485, Ethernet, and SPI interfaces, with robust protection functions like overvoltage, overcurrent, and short-circuit diagnostics. Design resources include schematics, BOM, Gerber files, and device datasheets for components like BQ78706, TMUX1308, and TMP61.
