On the Nissan Leaf, the CHAdeMO fast charging port connector exposes (one of) the car's CAN busses (a little in-car network). It's unauthenticated and has commands for charging and discharging the battery. The car doesn't need to be turned on, the vehicle computer wakes up any time that a charging cable is connected. The only security is a small door that covers the charging port, but I'm certain it could be jimmied open with a bit of patience. So yeah, it's absolutely possible to just walk up to a random Leaf on the street and extract DC power from it (e.g. to charge another EV or power an AC inverter) but you'd need to build your own cable and controller, and also 500VDC at 100A is extremely lethal so it's a terrible idea.... |
