What is a Battery Management System?

Have you ever wondered how a Battery Management System works? Erik Stafl, President of Stafl Systems, walks you through the basics, starting with two primary purposes of a battery management system for a lithium-ion battery pack: providing safe and reliable operation.

Topics Covered:
Purpose of a BMS
BMS Inputs
BMS Outputs
Current Sensors
BMS System Diagram
BMS Communication

The Battery Management System takes a number of inputs, including voltage, temperatures, and current among other inputs. The BMS then runs algorithms to create a series of outputs including state of charge (the fuel gauge), the state of health, the safe operating envelope ™, and any faults the battery pack may have.

Erik then describes how the BMS is used in a multi-cell application, using a system diagram.
