The RIT Electric Vehicle Team (EVT) designs and races performance electric vehicles to demonstrate the viability of electric drivetrains. We plan to begin working on an entirely new electric motorcycle, referred to as REV 2, beginning in the fall of 2017. One of the major challenges presented by this design is a substantially increased battery voltage over our existing drivetrain. The current battery management system is insufficient, in terms of measurement capabilities and dimensions, to satisfy the needs of this new motorcycle. Our goal is to design a new battery management system that is capable of an increased cell measurement count, while decreasing the overall footprint of the design.

A battery management system (BMS) is a crucial component in the design of an electric vehicle drivetrain. The safe charging and discharging of a lithium ion cell is only possible within a specific voltage range. Large lithium ion battery packs might have substantially different thermal characteristics at various locations in the pack, resulting in slightly different discharge rates between cells. The primary purpose of the battery management system is to ensure that the individual cell voltages throughout the pack remain close enough to one another such that no single cell is outside of its nominal voltage range. Secondary to that, a BMS is also capable of providing valuable information detailing the cell temperatures, overall state of charge, and alerting the drivetrain to any critically unsafe conditions.
