Charging while moving?

[Oba]

Oh it is definitely a RAV4-EV.

From what I know of Tony Williams he would never do anything like this particular push trailer.

This was also discussed in the in the RAV4-EV forums: Toyota Rav4 EV Forum View topic - Trailer range extender

Since he is quite publicly "anti-gasoline", I can't even imagine him trying it.

So you may want to check out plugless, the company that makes a plugless magnetic charging to allow the car to charge without plugging into the wall receptacle.

Meet Plugless | The Wireless EV Charging Station

Their system charges the model S by directly providing D.C. Power to the battery. It was reviewed by SAE international

https://avt.inl.gov/sites/default/files/pdf/evse/WirelessChargingTestResultsPaper.pdf

If they have already figured out how to charge using D.C. Power separate from Tesla I/f, wouldn't that offer an easier step to charging while in motion? Buy their system and tie into the on board adapter they install? I am interested because there was a line of 13 tesla trying to supercharge in Barstow. Only need an additional 50-100 miles to make this a non stop trip.

That paper is about the unit itself, and not about interfacing a particular EV. Also their version for Model S is still unfinished, probably dead ended. Somehow I don't see TM giving up any access to their vehicles such that this thingy would require. Philosophically Elon would be against giving up ~10% transfer efficiency which would be 'lost in space' with no hope of improvement.

Barstow - Tesla needs to build huge SCs on both sides of town, each one having its own C-Store slash Casino slash Tesla Gallery. Go for broke on this one!

You could just fire up the generator everytime you stop to eat or use the restroom. Just saying.

I'm seriously considering attaching a trailer with a generator to my Model S to make it possible to drive from Seattle to Alaska.

of course not, imagine if you could, many female drivers will have dragged the super chargers to another country or probably to Mars because they will not remember to unplug the charger to drive the car away just like dragging the the petrol pumps showed on youtube.

I have wondered about doing this since I first pondered buying a Tesla. Hacking the car seems to be a non-starter for me. I don't really want a maintenance headache. If Tesla offered an Auxiliary towable battery (which is as much as you could expect from Tesla) to extend the range of their vehicles, I might consider it.

Since someone brought up this old thread: I have noticed that if you put a substantial 12v (really around 15V) charge back into the 12V system on a PCS-equipped car (3/Y/Palladium), it will reverse the flow through the DC-DC and charge the HV system. Not sure what the limit of this is, I only had about 20A going in after the about 30A 12v overhead from my 50A capable power supply. Note that this may not be safe for the 12V battery, I did this on a lithium 12v equipped car and not see the BMS disconnect on the lithium when it went from 80% SoC to 90% SoC so I stopped. On a lead-acid this also presents problems because it will consume any overcharge and electrolysize the electrolyte, thus removing all the water from it. Also the PCS is limited to about 3kW peak.

I guess at some point I could hook my turbine trailer (I still have it) up to my Tesla and see what happens. I bet there's no problem doing up to 30kW as long as you are driving. I can also program the turbine to only spool up to attempt to zero the powertrain current. (so it will only match drive power, not charge)
