STMicroelectronics STEVAL-BMS114 Battery Management System (BMS) Evaluation Board operates from 1 to 31 Li-ion battery nodes and supplies an elaborate monitoring network to sense each cell's voltage, current, and temperature. Each battery node manages 4 to 14 cells for a voltage range between 48V and 800V. The board implements the L99BM114, a multicell battery monitoring and balancing IC, for battery node status through stack voltage measurement, cell voltage measurement, temperature measurement, and coulomb counting. Measurement and diagnostic tasks can be executed either on demand or periodically, with a programmable cycle interval.
