I wonder what he is thinking behind that little smile; Crazy Americans!

so where is the turbine exhaust?

The intake is on the axis (through the generator) and the exhaust is covered up with the black duct tape. The exhaust temp is ~500F.
2011 LEAF (Silver SL+QC) - 6/24/11 (on 2/3/08 reserved an Aptera 2e #372)
AV EVSE, plus Ingineer's 240V upgrade, and a fist full of adapters

6.5 kW PV, making ~24 kWh per day (average).

In those photos the exhaust is capped off.
When working there would be a fat/curved exhaust pipe coming up from where you see the black circle (cap).
He didn't have everything all hooked up in fully operational mode just then.

He showed off a "piggyback" replacement power cable that he said can be used to put DC voltage directly into the pack and/or run the drive inverter. I don't think he has to do anything special with the regen circuitry.

This video will give you some idea how the turbine sounds when it is running (similar turbine on a different vehicle):

Very cool setup. FYI I had one of those Harbor Freight/Northern trailers and found the tongue to be too short for smooth maneuvering so I extended it with square tubing, makes backing up easier, but of course makes the whole setup longer. I wonder if the genset is light enough to work with one of those single swivel wheel trailers?

You have to admit, it solves many issues, such as the "demand charges" for L3 DC fast chargers, and its probabably the lowest cost fast charger availble. Of course you are substituting propane and some local pollution for those demand charges.

Its very clever, and when Phil gets it worked out, I bet he could sell those setups to AAA for Leaf rescues, and probably to many car rental agencies, who rent out Leafs, its probably cheaper than those CA demand charges, and it's mobile, so doesn't require all of the permitting and expense of a fixed installation.

I am confused as to what this actually does. Does it provide power on the run, recharge the battery or both?

Both, is what his plans seem to indicate. Its a mobile propane powered turbine generator w/ a DC Fast charger (30KW), and looks like he's finding a way to connect it to the pack for recharging while driving as well.

Yes, it has 2 modes; Range Extension and Mobile CHAdeMO QC. They are independent functions. The function I currently am closest to finishing, and might even have working this week, is the range extension function. Surprisingly, The QC function requires much more engineering and testing.

When it's in Range Extension mode, it basically tracks the cars utilization so there is essentially no battery usage, though it can be set to also recharge the pack if it's low. The point is to take a long highway drive, running the turbine, then shut down once you get off the highway at your destination and run on battery. The turbine is most efficient at higher power levels, so it is happiest at about 70mph or better. =)

The mobile CHAdeMO QC function allows charging any CHAdeMO equipped car at a 30kW rate. Most current stationary CHAdeMO chargers are capable of 50kW, even though the LEAF doesn't pull the full 50kW for long if at all. (I've only ever seen it peak at about 48kW) This means a full QC could take about an hour, but it should be able to do 80% in a half-hour is you aren't totally flat.
