A Battery Management System for lithium ion batteries, in electric vehicles and buildings

Download this project as a .zip file Download this project as a tar.gz file



A battery management system for the protection of Lithium ion battery cells as used in electric vehicles and building power systems. A small printed circuit board is mounted atop each cell, which performs bypassing and monitors for high or low cell voltage or temperature.

This design has been optimised for high voltage isolation, to withstand high forward and reverse voltages under fault conditions without creating arcs that could ignite flammable vapour, for autonomous operation, to use fibre optics for comms, not to require physical access for reset or firmware update, and to have low cost.
