Re: Charging while driving

Nothing different is really needed even with the current car other than unlocking the programming so that it would go into drive with the gen-trailer attached to the quick charge port. It wouldn't really be safe in it's current form with a cable running up under the car to the front but the engineering to make it work at the factory level would be no big deal right now other than the cable routing. Especially if you didn't mind turning the generator on and off manually as it was needed. If the charge ports were in the back somewhere, it would be plug and play right now with a minor software tweek and a button whereby you confirm that you know you are driving with the charger plugged in.

So from what I can see if u can hook a trailer with a generator on it u can charge while driving. So has anyone ever done a write up on this?

viewtopic.php?p=257630#p257630 has some links. I saw Phil's turbine engine tow generator as I was present at that meeting.

This would be beyond the average hobbiest. And the onboard 6.6kW charger wouldn't be enough to keep up at highway speed even if you could get it to come on while driving. Maybe a custom generator to tap 370v DC at 20 kW right on to the battery terminals?

As has already been said here, it has been done, using a generator. It has also been done using auxiliary battery packs. And it's done by every LEAF via regenerative braking. It is not impossible and it is not a new idea.


regen and charging at the same time has not been done. having another battery pack is a COMPLETELY DIFFERENT THING

Ok, Ill bite with my long range fantasizing... How about an additional 1772 charger port in the rear of the car. That way you can have a hitch mounted 7K generator and a portable EVSE while you drive. That could get you a couple hundred of miles before you would have to stop for a rest and get a full main battery recharge again!! Sounds like a Super-Volt here..

If anyone does this, I get half for the idea....

Heck, why stop here... If you have two charging ports, then use TWO Chargepoint chargers at the same time and charge up the Leaf in only 1 hour!!

Obviously the quick charge port should be in the back because it takes 15-20 kW average to zip down the highway at 70 mph. I think Nissan would be very surprised how much the market would open up if they offered a gen trailer rental.

They are all examples of charging while driving. It hardly makes sense for us to split hairs when the original question is so vague.
I noticed you're still working with polymers.

I'm surprised nobody has mentioned a pusher trailer.

No electrical connections at all... the trailer is a self contained powerplant and drive motor, connected to the car with a trailer hitch.

Yes, you could do this with a simple generator and an electric drive motor that powers the two trailer wheels. The generator can then be used at your camping spot to fully charge the onboard battery when you're stopped.

The problem with most of these ideas is that the people that want them rarely have the money and expertise to make it happen. Buy a Volt, or the BMW i3 with 650cc twin cyclinder gas motor. Actually, find the EPA compliant BMW motor in a wrecking yard and use it. Or, a nice Honda generator. Here is a loud generator that should do the job with a simple 240 VAC motor:

Honda EB10000 - 9kW - 240 volt AC @ 37 amps continuous
