STMicroelectronics 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.
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 STMicroelectronics EVL9965T or EVL99BM2T transceiver board and MCU board (SPC582B-DIS or Nucleo-L476RG).
Features
- BMS controller board supporting up to 18 cells in series
- Number of configurable cells using jumper SMD with a compatible load board to simulate 18 series-connected cells
- Ten configurable GPIOs, usable as:
- Inputs for NTC temperature sensors
- Digital lines to interface external SPI
- I2C memories/peripherals
- Enables safe bench evaluation and validation of BMS functions without a real battery pack
- Fully synchronized high-accuracy measurements on cell voltage, busbar, and stack voltage with dedicated ADC
- SPI target for direct MCU interface
- A dedicated GUI is available for configuration, monitoring, and evaluation with dedicated firmware
Applications
- Automotive battery monitoring systems
- Energy storage systems
- UPS
