The STMicroelectronics Battery Management System (BMS) evaluation board that manages from 4 to 14 battery cells. The main advantage of this evaluation board is ensuring isolated connection to an external MCU, due to the embedded transceiver. The board is based on the L99BM114 Li-ion battery monitoring and protection chip for high reliability applications and the L99BM1T general-purpose SPI to isolated SPI bidirectional transceiver. The main activity is monitoring the cells and battery node status through stack voltage measurement, cell voltage measurement, temperature measurement, and coulomb counting.

Current sensing of the entire battery node

5 GPIOs to connect temperature sensors as NTCs

CN1 connector that allows establishing communication with an MCU board via SPI

CN2 connector that interfaces directly to an MCU board for control and diagnostic functions

Passive balancing

Compact size 100 mm x 76 mm
