AEK-POW-BMS63EN

AEK-POW-BMS63EN is a battery management system (BMS) evaluation board that can handle from 1 to 31 Li-ion battery nodes. Each battery node manages from 4 to 14 battery cells, for a voltage range between 48V and 800V. The board is based on the L9963E, which is designed for operation in both hybrid and full electric vehicles using lithium battery packs, but its use can be extended to other Transportation and Industrial applications. The main activity of the L9963E is monitoring cells and 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. Measurement data are available for an external microcontroller to perform charge balancing and to compute the state of charge and the state of health. The monitoring function is related to the measurement of the battery current, voltage, and temperature.
