Re: Towable Turbine Powered CHAdeMO Charger

Wed Dec 07, 2011 10:25 am

Guys:

This is my trailer. It's a dual-mode combination Range Extender and also a mobile CHAdeMO quick-charger.

It's a 30kW Capstone Microturbine. It's not an Aircraft APU. It has air bearings, 40,000 hour life, and 1 moving part. The emission profile is cleaner than almost all other ICE motors. It is configured to run on Propane, but can run on most any fuel.

I am not using a Manzanita Micro charger for CHAdeMO. The Capstone has a dual-inverter (triple in some configurations) architecture, that has 2 inverters back-to-back. The output inverter is controlled my a custom microcontroller based system that allows interface either to the Leaf directly while driving, or to a CHAdeMO equipped EV while parked. It does not bypass any safety systems anywhere, and uses the CHAdeMO protocol properly to charge the vehicle (parked only).

While underway, the range extension function basically provides traction power for the Leaf indefinitely, and can also add charge to a depleted pack. It does not bypass any of the Leaf's safety systems or the Battery Management system. The GOM (Guess-O-Meter) seems to even be able to somewhat figure it out. As you drive and the range extender provides power, the SOC doesn't drop, so your range stays high. It is intended to be operated only on long highway trips, as it would not be efficient at low power levels.

The whole trailer as shown configured in the picture weighs under 500lbs.

It is not currently for sale, it's still under development. It's a proof-of-concept system.

Yes, I had to make a custom trailer hitch to connect it to the Leaf. No, I will not sell the hitches or provide plans, kits, etc.

Any other questions? =)

If you are local to the Bay Area and wish to see it, I hope to bringing it to San Jose this Saturday to the combined BayLEAFs and EAA meetings.

It isn't 100% electric if you have to put gas in it.

Oh, and FYI: To connect the range-extender to the Leaf there are no permanent modifications made to the Leaf. It is connected with a connector and is reversible in a few minutes back to stock.

And for those that don't know, the Japanese Guy in the picture is Hidetoshi Kadota, Nissan's Chief Vehicle Engineer for the Leaf. (CVE) He had a lot of questions for me!

Is that an extra connector direct to the battery in the first pic?

I bet he did have questions for you!

Oh and BTW... I recommend EVSEUpgrade.com to everyone I talk to about the LEAF. :)

It's not "extra", it's where the battery connects the the High-Voltage Junction box/DC-DC Converter. The Range extender connects between the battery and here.

Thanks! If it isn't obvious by now our mission is to see the Electric Vehicle succeed. We will do anything we can that furthers this cause!

So is that orange boot, looks like it is laying horizontaly below the connector, connected to the battery and normally plugged in up there?

No, the connector that normally mates to that one is not in the picture. It continues down under the car in the "tunnel" and connects to the pack. The orange boot you are referring to is the 3-Phase connection from the inverter to the drive motor. (That is the motor it's going into).

Incredibly sexy. I am in awe of what you do.

Which reminds me...since you're the only person to have the shifter mechanism apart that I know of, does it seem robust enough in construction to be abusing it via frequent "gear" changes between D and ECO?

Thanks! The Capstone is definitely Engineering Porn! =)

I've covered this in another topic, but yes, it's Hall-effect, so no contacts to wear out (except for the park button). It will outlast the car even if you shift it constantly. If anyone wants to respond to this, Please make another topic. It's bad enough I even responded!
