A friend just got a new Ford F-150 Hybrid with the “Pro Power Onboard” feature which is a 7.2kW inverter. It provides a L14-30 receptacle (along with four NEMA 5-15 receptacles).
So of course this test *had* to happen. 😉 It would be a great way to “rescue” stranded EV’s.
It looks like neutral and ground are bonded together inside the F-150 which is good as the Tesla will refuse to charge otherwise (easy to accomplish though if needed).
The truck idled at about 1000 RPM. Way quieter than a portable generator!
I am curious if the Ford would put up with hours of charging at this rate? Technically, EV charging is always considered a “continuous load” under NEC and so you are supposed to only pull 24 amps (80%) on a 30a circuit. But I don’t know that NEC even applies here as it is not a structure? The truck says it is rated for 7.2kW so why not?
So we are loading the truck right up just about to its limit. I would be curious if it would put up with doing this for a full charging session? We just tested for a few minutes to prove it was possible. 😉
I have a video of this as well but Reddit does not yet support video.
