A continuation from one part of a previous project, RPi Digital Dash, I set out to design a power supply unit and battery back up for using a Raspberry Pi on a FSAE vehicle. Our team implemented a custom data logging and telemetry based on a Raspberry Pi 5 and struggled with file corruption due to the sudden loss of power. A few basic requirements were defined, such as taking 12-24V input, reverse polarity protection, over-voltage, 30 minutes runtime after power loss, and support for CANBus connectivity. Further requirements were refined based on power consumption estimates and evaluating different battery back-up methods.

This project is a work in progress, and has yet to be completed.
