In december 2023, Loïc, Thibault and Marc embarked on a journey to convert a 2007 VW Polo into an EV using only off the shelve components such as Raspberry pis and Arduinos. Today, the car is drivable, and can even be controlled remotely. The entire software they wrote for it is open source and built using Elixir, a language running on the Erlang Virtual Machine (the BEAM). Their platform uses CAN communication to serve as a gateway and translate messages from the different components they used for their project (A nissan Leaf motor, a Tesla brake booster, and more...). In this talk, they will drive you through the process they went through to get to a fully working car and give some insights on how they made everything work together.
