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:
