STMicroelectronics Battery Management System Module Based On L9963E And L9963T Evaluation Board Evaluation Board [AEK-POW-BMSWTX]; 277-650

The STMicroelectronics Battery management system Evaluation board manages from 4 to 14 battery cells. The main advantage of this evaluation board is ensuring isolated connection to an external MCU, thanks to the embedded transceiver. The board is based on the L9963E Li-ion battery monitoring and protection chip for high reliability automotive applications and the L9963T general purpose SPI to isolated SPI bidirectional transceiver.

Voltage monitoring of every single cell and of the entire battery node

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
