Smart Battery Management for Mobile Robotics 7-14 Cells

The MR-BMS771 is a standalone battery management system (BMS) reference design suitable for mobile robotics, such as

drones and rovers,

supporting 7- to 14-cell batteries.

The design is suitable for other applications, such as portable medical devices, high-energy power tools and

personal mobility (wheelchairs/scooters), all of which benefit from high-quality battery control.

The MR-BMS771 features a 7- to 14-cell voltage measurement, pack voltage measurement and output voltage measurement,

as well as current sensing (coulomb counting), 1 to 3 possible cell temperature sensors and power switch. Other

features include 2 controller area network (CAN) buses, inter-integrated circuit (I²C), display, near-field

communication (NFC), universal asynchronous receiver-transmitter (UART) 12 V 1 A output and secure element.

The S32K146 microcontroller unit (MCU) allows for complete software flexibility and communication via CAN/unmanned

aerial vehicle CAN (UAVCAN) or I²C/system management bus (SMBus).
