The system is for a Formula SAE (FSAE) Electric style race car. FSAE is a collegiate competition, and I'm part of a US Pacific Northwest team. Our car uses a 550 V battery and is 4WD. Most of our electronics and firmware/software are in-house besides motors and inverters. I lead the telemetry project and work with 1-2 other members on the system.
The system consists of an on-vehicle computer (Raspberry Pi or NXP i.MX) and a ground station (Rockchip RK3588S). We use Python heavily and the real-time dashboard part is done with InfluxDB and Grafana. Both computers and any user devices are on a Wi-Fi network made with a long-range WISP access point.
Our team is unfortunately very light on public tech blogs and how I wished I can change that... There is plenty of information on FSAE electric cars, vehicle telemetry, and both on the internet and they were a source of inspiration as I designed my own solution.
Awesome. If you dont mind me asking, what sort of dashboarding/visualization software do you use? Highchart homebrewn web apps? Some closed source auto software? What's that world look like? Always been curious about it from a front-end perspective.
Real time data is fed into an InfluxDB instance and shown on Grafana hosted on the ground station. This data is downsampled to cope with the volume of raw traffic. We also tried some solutions used by other teams like KX [0] but decided to go with a FOSS stack. A post processing pipeline converts original data to a however proprietary format used by AEMdata [1], a proprietary data analysis tool from our ECU vendor and used somewhat commonly in the racing scene.
