EVL9965A/EVL99BM218 Promotional Boards

STMicroelectronics EVL9965A/EVL99BM218 Promotional Boards integrate the L9965 BMS device, a complete battery pack monitoring, balancing, and protection system for Li-Ion and Li- Polymer cells. The EVL9965/EVL99BM218 evaluation kit consists of an expansion board containing the L9965 IC for battery pack monitoring solutions, along with a load board. Equipped with a high-precision ADC, the device continuously measures individual cell voltages, total stack voltage, and temperature via an external NTC sensor. These voltage measurements are performed cyclically with a configurable timing loop.
