SAE Hybrid Vehicle: Battery Box and Management System

Recently, efficiency and performance have become increasingly important in auto racing. Because of this, future engineers are moving toward hybrid and electric solutions. The Society of Automotive Engineers (SAE) hosts an annual competition for schools to showcase student car designs. To keep up with the shift to hybrids, the FAMU-FSU College of Engineering SAE team wanted to compete in 2023 with their own formula hybrid car. Our project added to last year’s project by focusing on the electrical parts. This included batteries and a battery management system (BMS) protected within a box. 

The BMS checks the battery’s state of charge, power and temperature. The project features included cooling and analysis of the box, as well as combining the batteries and the BMS. The cooling consists of two fans circulating air throughout the box. Box analysis made sure it would stand up to impacts and verified that box temperature would not exceed dangerous levels. The batteries and BMS were wired together and tested to ensure proper compatibility. All parts properly fit together when used in a simulation tool before building. The finished product was a small-scale physical model and a digital full-scale model for a specific electric motor.
