Lithium battery BMS

OSM Battery pack integrated circuits and designs help you to layout your Battery Management System. Careful design considerations on charging and discharging processes on battery protection and cell monitoring will support you throughout your design. From 2S, 3S, 4S,7S and 8S, 16S. and even high voltage BMS.

A battery management system can be comprised of many functional blocks including: cutoff FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real-time clock (RTC), temperature monitors, and a state machine. There are many types of battery management ICs available. The grouping of the functional blocks varies widely from a simple analog front-end that offers balancing and monitoring and requires a microcontroller (MCU), to a standalone, highly integrated solution that runs autonomously
