Model 3/Y prob others to get AC output

[Cosmacelf]

All the articles talking about this are hyping the vehicle to grid aspect or being able to draw significant AC power from the Model 3/Y (and presumably other Tesla vehicles eventually).

Basically, an engineering who reverse engineered the Model 3 on board charger, the circuit board that converts AC to DC to charge the car at up to approx. 12 kW, has found that the circuit is completely bidirectional. Meaning you should be able to extract that amount of power from the car with just a software change (and presumably some external simple hardware box that provides safety ... you wouldn’t want to flip a software switch in the car and electrocute someone at the other end of a cable).

Now, V2G is nice and useful, especially now that solar power is creating this enormous duck curve that has become a real problem (here in CA, the cheapest electricity is available Weekdays from 10:00am until 2pm!).

But what this also enables is significant external power that would replace small portable gas powered generators that people use for all sorts of reasons. Construction contractors. Bounce house operators for picnics. Beach or camping entertainment.

Tesla poised to unlock vehicle-to-grid abilities with 'bi-directional' charging systems

So this engineer, who really knows his stuff has found that late 2018 cars, at least, do not have bi-directional charging capability.

I guess it all depends on what you want to run. Will the car cut off the power if the batteries reach a certain discharge rate During and after a disaster I would want my car to have a full charge at all times.

Longer term it SEEMS TO ME ~ 50 volt DC would be a "better solution"
- smaller wire gauge
- still sage "low voltage" - right?

comments from those that understand these things ??

thanks.
