I think that's exactly what the OP is wanting to talk about. I'd like that too, or even settle for a J1772 "jumper cable". If the cost is reasonable, of course.TEG said:How about a CHAdeMO "jumper cable"?
Your friend is stranded with an "empty" Leaf.
You pull up in your "full" leaf, and hook up the CHAdeMO to CHAdeMO and quickly transfer some of your charge over?

Really? Couldn't you do something like a giant resistor that slows current flow? It seems like they could just equalize each other without a full L3 charger type circuit. The L3 stations tend to be converting 3 phase AC to DC. Also one Leaf pack has a similar DC output to another, so it wouldn't necessarily have to do the same type of voltage conversion as a standalone L3 charger that is starting from line current.Herm said:The siphon cable would need a DC-DC converter that could handle 500V and a lot of amps.. expensive... otherwise there would not be any way to control the current flow if you connected a fully charged pack to a discharged one, there could be more than 100V difference between the two packs and massive currents. Much easier just to bring a generator.
Such a siphon cable would be almost as expensive as an L3 charger.

Don't the QC DC lines connect directly to the pack?
I imagine there is a signal you send to close some relay or some-such to have direct access to the pack.
I wouldn't think they would have one way diodes or anything like that... Why couldn't you get pack power out of the CHAdeMO port?
The J1772 on the other hand goes to the input of the charger...

Pull both cars nose to nose with their drive wheels on the dyno ramps and connect the opposing sprockets with a chain drive. Chock both vehicles and put one car in reverse and the other in drive. Hit the accelerator on one while the other regens. You'd have to experiment to see which direction works best.

Its a good idea to keep a spray can of carburator cleaner handy, keeps small generators from getting fouled up.. just a quick blast into the carb while its running does the job, remove the air filter first.

rainnw said:I'd expect that in the future, maybe, maybe not, the standards will be modified for grid storage initiatives. That way your car battery pack can store cheap off peak wind power and sell it back to the grid during times of high demand....and maybe you could devote some of your battery pack to this purpose if you intended on driving minimal distances.
