Formula SAE (FSAE) is an annual collegiate design competition that takes place across the globe. Portland State University’s team, Viking Motorsports, was committed to designing an Electric Vehicle (EV) for the 2021 FSAE competition. The team designed a completely custom lithium-ion cell battery that is managed by an Orion BMS 2 battery management system. The FSAE rulebook requires a robust temperature monitoring system for any EV power supply. The Orion BMS 2 can only directly collect data from eight temperature sensors, which is not enough to meet FSAE regulation. However, the BMS can be configured to monitor many more sensors through the use of the Controller-Area Network (CAN) protocol. This thesis documents the creation of modules capable of collecting and transmitting data from hundreds of temperature sensors via CAN. Software and hardware designs were driven by requirements established at the start of development. Once complete, modules went through a series of tests to ensure all requirements were met.
