This board allows battery data to be accessed remotely over CAN using a low-power STM32L4 microcontroller. It connects to a BQ34Z100 State-Of-Charge tracker built in to the battery to provide current, voltage, and other feedback.

Main Features

• Modular architecture (run up to 253 batteries in parallel!)
• Low Power STM32L4 microcontroller
• CAN 2.0B communication interface
• Rich feedback with an RGB LED and buzzer
• Separate Charge / Discharge control
• Battery fault recovery capabilities
• Integrated Bootloader
• BQ34Z100 data readout (Current, Voltage, State of Charge, etc.)
• Reverse polarity protection
• Integration with the HEBI Platform through the use of the Battery Controller
