This presentation walks through our efforts reverse engineering the Zaptec Pro charger, an electric vehicle charger found in many parking lots and apartment buildings around Norway.

The presentation shows how we went about testing the device, including some of our trials and errors during the process. By analyzing the device’s firmware, and compiling a custom bootloader, we were able to root the device and dig into how it works.

Although we found that security appears to have been considered at multiple steps along the way in developing the Zaptec Pro charger, the presentation also presents some potential improvement areas.
