STMicroelectronics STEVAL-BMS114TX BMS Evaluation Board
STMicroelectronics STEVAL-BMS114TX Battery Management System (BMS) Evaluation Board operates from 4 to 14 battery cells. The board uses the embedded transceiver to ensure an isolated connection to an external MCU. Based on the L99BM114 Li-ion battery monitoring and protection chip, the board facilitates high-reliability applications and the L99BM1T general-purpose SPI to isolated SPI bidirectional transceiver. The L99BM114 monitors cells and battery node status via stack voltage measurement, cell voltage measurement, temperature measurement, and coulomb counting.
The STMicroelectronics STEVAL-BMS114TX supplies an elaborate monitoring network to sense the voltage of each cell and the current of the entire battery pack.
Features
- 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
- 100mm x 76mm compact size
Applications
- Industrial Battery Management System (BMS)
- Portable and semi-portable equipment
- E-bikes and e-scooters
- 48V and high-voltage battery packs
