Kona electric vehicle CAN bus decoding #ReverseEngineering

Project Gus is looking to make an electric vehicle (EV).  Part Zero and Part One took the long way around on an EV conversion project by purchasing a crashed Hyundai Kona Electric for parts.

The next step is to talking to the vehicle CAN bus. This is how various parts of the car “talk” to each other.

I’ve uploaded many log files, captured on various Kona EV CAN buses from two different vehicles (mostly PCAN – Powertrain CAN).

The approach has been to capture logs in advance and analyse later, rather than doing interactive analysis on a running car. This is because all the Konas we are logging are wrecks that can’t drive on public roads, and they are steadily being dismantled.

The goal is to figure out what the message contents represent – what signals are encoded in each CAN message payload. This is like identifying individual needles in a haystack packed full of needles…
