Product overview
Description
The promotional board integrates the L9965 BMS device, a complete battery pack monitoring, balancing, and protection system for Li-Ion and Li- Polymer cells. The L9965/L99BM218 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 external NTC sensor. These voltage measurements are performed cyclically with a configurable timing loop.
A dedicated graphical user interface (GUI) is available for configuration, monitoring, and evaluation with dedicated firmware. Together, these tools enable simple and fast evaluation of the battery management system solution for use with the EVL9965T or EVL99BM2T transceiver board and MCU board (SPC582B-DIS or Nucleo-L476RG).
