BMS Printed Circuit Board Assembly Electronic PCB Assembly


What is BMS?


A BMS is a Battery Management System—the electronic “brain” that keeps a rechargeable battery pack safe, reliable, and long-lasting.
It is almost always built around a dedicated BMS PCBA (assembled circuit board) that is mounted directly on or inside the battery pack.



♦ Key Jobs the BMS PCBA Continuously Performs: 

  • Key jobs the BMS PCBA continuously performs:
  • Cell-level voltage monitoring (over-charge & over-discharge protection)
  • Current monitoring (charge/discharge over-current & short-circuit cut-off)
  • Temperature sensing (thermal run-away prevention; heater control in cold)
  • Cell balancing (bleeds charge from higher-voltage cells so the pack stays in balance, raising usable capacity and life)
  • State-of-charge (SOC) & state-of-health (SOH) fuel-gauge calculations
  • Communication (I²C, CAN, UART, BLE, etc.) to host device or charger
  • Power-path / pre-charge control (hot-swap inrush limiting, sleep-mode MOSFETs)
