Trying to find a necessity for its V2V ORCA INCEPTIVE on-board CHAdeMO to CHAdeMO charge system (kinda just rolls off the tongue doesn’t it?), Andromeda Power demonstrates how the Nissan LEAF could rescue a Tesla Model S.

Oh really?

However, it seems like a lot of work and equipment to make the energy flow between cars.

First you begin with a Nissan LEAF and its CHAdeMO inlet, but then to discharge LEAF you need to use a CHAdeMO bi-directional charger and have V2V ability.

ORCA INCEPTIVE then sends DC power out through the CHAdeMO system to the… CHAdeMO Tesla adapter. Enabling the Tesla Model S to get a fractional charge.

The real problem here of course is that Tesla Model S has more than 2 or even more than 3 times battery capacity than the LEAF, and most likely the LEAF has traveled from somewhere (and has somewhere to go after the booast), needed to retain some of its own capacity.

So basically…we believe it will be a pretty rare sight to see a Nissan LEAF (with spare kWhs to burn) rescuing a stranded Tesla Models S.  Our hunch is that a Tesla owner would rather just catch a tow to the nearest charge point if somehow they found themselves out of power for some unknown reason.

But if you ever need this feature, Andromeda Power even provides a smartphone app for the process.

Here is an earlier video of the system in action between a couple LEAFs:

Replace the Leaf with a AAA car with a 300 kw battery and now we are talking…

AAA does have charging trucks with on-board ICE generators. J1772 and CHAdeMO if I recall correctly. However, they found that they are rarely used.

In certain parts of the country with widely traveled corridors (i.e. I-95 in the northeastern US) AAA has mobile chargers available in vans/trucks for this purpose. From what they told me on the phone, the idea is to give you enough charge to get you to a nearby charging station.

Of course they are rarely used. There are still very few EVs on the road and most people that do have EVs at this point are smart people that don’t Broder.

I have to wonder if it would work the other way around with the Tesla charging the Leaf. Probably the only thing that could prevent it is if Tesla is monitoring the direction of energy flow and would cut it off.

I think it’s funny that the “EV Stranded” vehicle in the smartphone image is showing 53.3% SOC. Doesn’t look very stranded to me.

In Japan, a Prius Prime can use Toyota’s external power supply adapter to let its 8.8 kWh battery and/or ICE engine charge a Tesla at about 1500 watts. Just sayin’.

A simpler way would be to tow the dead car with an electric or ICE car. The regen will charge the dead car.

No supermodel required.

Not required, but still appreciated. 🙂

Teslas have been experimentally towed a few times by ICE cars and other Teslas. Here is an article with a video on Nov. 2016, made by Bjorn Nyland. A model S is regenerated by a tow with a Model X and a rope.

* They find about 80% of the extra X power used, went right back into the S battery as usable power.

* They find you tow the S 2/3 of the way to a destination like a Supercharger, it will gain enough juice to go on its own power, the remaining 1/3 way!

Doesn’t sound like much of a usable solution.

When they’re done, how does the Leaf get back to a charge point? If the charge point is that close, the Tesla could probably have made it by managing their energy better.

V2H would be a good thing though.

@sven – lol 1500w.

It’s usable because you don’t fully discharge the Leaf. You only give it enough charge to make it to the next charging station.

If you’re in Japan and want a faster emergency charge than 1500 watts for your depleted BEV, you could get 100 kilowatts of electric power from the CHAdeMO DC socket found in the trunks of either the Toyota Mirai or Honda Clarity for up to about 60 kilowatt-hours worth of electricity. But beware that there might be a stigma attached if certain EV enthusiasts found out that you charged your BEV from an HFCV. 😀


Might be the one thing more rare than a LEAF with excess pack capacity.

Or I could just have some umpa lumpas whip up some electrons using unicorn magic. Well see which of the three charge up my stranded Tesla first. 😀

So then, it is possible to find a useful purpose for a fool cell car after all! That is, if you look hard enough. 😉

I haven’t really heard of many Tesla Model-S being stranded in the first place. It’s usually the Leaf that would be stranded.

This is an important technology to develop!

One of the remaining hurdles for EV adoption is the ability to rescue your friend without a tow truck. I’ve rescued friends a few times with a simple tank of gas, but there’s currently no equivalent for EVs. You always have to resort to an expensive tow. Fine for us wealthy early adopters, but not fine for everybody else in ten years.

Vehicle to vehicle charging is the solution! This article poo-poos it because the source vehicle is a Leaf and the Tesla has a much bigger battery, but the destination car only needs enough of a charge to get to a charging station. I didn’t need a 15 gallon gas tank to rescue my friends because a 2 gallon tank got them to the next gas station.

So yes, this particular (early) implementation is complex, and the source vehicle isn’t ideal for the task, but refining this technology will be NECESSARY before EVs can replace ICEs.


The technology is good, even if the example is somewhat contrived. Nobody would have batted an eyelash if they simply would have done one Leaf to another Leaf, and not drug some other car maker into it. But they had to go there…

Expensive tow?!?

Get better insurance that includes towing in its road side assistance package.

Towing is rare in any vehicle. I can’t remember the last time I had to rescue someone out of gas… maybe 10 years ago because of a broken gas gauge?

It’s a neat trick to charge across vehicles, and to have, say, an universal aux out port wouldn’t be bad, but not quite a priority as there are very few extended range ev’s anyway.

The people who can afford to get better insurance with road side assistance usually aren’t the same people running out of gas. I’m talking about teenagers and other people who are short on money, not wealthy early adopters like us.

This is more than a neat trick, it fixes a major shortcoming of EVs. This WILL be required when EVs are truly mainstream.

It’s not even very complex. Power needs to be able to go both ways, which current implementations of V2G already support, and you need some software for the two cars to communicate.

Ah, no. Definitely not.

Did you actually look at the photo above? See the size of that metal box in the back of the Leaf? Nobody is gonna carry something like that around in the back of their car on the off chance that they might come across a BEV stuck at the side of the road and needs a charge. This ain’t like carrying a 1 gallon gas can in the back of your gasmobile.

As has already been posted, the AAA has dedicated charging trucks, which can deliver a lot more power than the Leaf shown here. That is the proper solution, not the one in this article.

In one way the towing option is far better than with an ICE car, in that you don’t even have to carry the gas can (only a tow rope). I would like it if the manufacturers facilitated this rather than discouraged it (in the Leaf they “ban” towing, and if you (as I have once) reach close down mode,it firmly puts the car in Neutral, so you can tow but not generate). I carry the tow rope so I can be rescued by anyone!

If Leaf could tow 5000 lb, it could simply tow Tesla while having Tesla charge the batteries via regen, no special adapter needed (other than tow bar). Added bonus is if Leaf is going the same way as Tesla, they both save time by charging while traveling.

Since Leaf can’t tow (officially), it would be better to always travel with a sexy girlfriend. Those big burly guys screech stop their giant pick up truck to help a pretty girl in distress.

If your sexy girlfriend isn’t with you when your BEV runs out of charge, then those same big burly guys in their giant pick up truck will roll coal on you and your BEV! 🙁

There are two workarounds: 1) don’t run out of juice. 2) always keep a sexy girlfriend.

I’ve managed to never run out of juice, though I came close when DCFC wouldn’t work properly on the way to drive-electric-event. There was a pretty girl in the car, though.

In addition to giving a friend a quick juice-up to get to the nearest plug, it would be nice to be able to use my EV in place of a backup generator to keep the lights in the house on in the event of a power outage.

Oh they could come up with more “fun” videos than this: 1). My VOLT could resue my ELR if the ELR was totally dead (no gas or juice) by opening the hatch of the VOLT: 2). Hooking up my 1500 watt (peak) Harbor Freight “Junk” Tools Inverter to the 12 volt battery, with the ‘ignition on’ so that the 140 amp 12 volt charger in the volt keeps the battery fresh. 3). Run a 100 foot, 120 volt extension cord between the 2 cars (one advantage of the high ‘transmission voltage’ is that the cars don’t have to be physically that close). 4). Plug in the ‘occassional charger cord’ and let the thing charge for a while at 8 amps – about 20 or 25 minutes per mile. You’d just let the thing go as long as necessary – (of course, the volt would arrive with enough juice in its big battery to prevent having to run the engine at all). Now, when I had my Tesla Roadster, there were times during february when I was at a public docking station, where the TSL-01 (the barrel twist-lock cord connector) FROZE TO THE CAR!! – and you have to shut the… Read more »

Bring gas. Jumpstart ELR. Mountain mode

Well tow trucks are expensive, and As I said I fixed my stranded problem with my Roadster myself.

Gas can won’t work very well for that brand of car. But it does sometimes work with an ELR or VOLT provided the fuel pump hasn’t burned out ( I learned never to run out of fuel in that car because if you do it will burn out the fuel pump.)

If you read Cosmo, when a woman twirls her hair while wearing a tight dress and pushup bra it means
she wants to have sex with you…

I think the actual “rescue” of a stranded EV driver is best accomplished by sending a gender appropriate super-model. No cables required.

What would be useful is to have a normal outlet in your electric car. So that you could get electricity at remote areas (or whenever you are too lazy to get an extension cord).

Then that outlet could of course also be used to charge another car in need, if that would ever happen.

More utility in a car is never wrong.

I guess you didn’t see Bill Howland comment.

“Hooking up my 1500 watt (peak) Harbor Freight “Junk” Tools Inverter to the 12 volt battery,”

Indeed, this is how I run my chain saw at my property since extension cord cost more than the inverter.

Perhaps nobody noticed that the vehicle to vehicle charger could be used from any CHAdeMO equipped car? It wouldn’t have to be a LEAF.

The “super model” is Heather, by the way.

The simplest, cheapest, and less bulky / lightweight solution is exactly what was suggested above.

Each of us should have a minimum 1000 watt CONTINUOUS portable inverter with pure sine wave. XanTraX is one of the better brand names. Expect to pay up to about $500.

Then, ANY vehicle with at least a 100 amp alternator / 100 amp DC to DC converter can recharge your vehicle at 6-10A and 120 V.

Virtually every electric vehicle sold comes with a cable that can charge at 12 amps, however, it would be advisable to have a cable that is adjustable between 6 and 10 amps. You will add about 2 miles per hour at 6 -10 amps, but risk overloading the system at 12 amps.

Tony is of course technically correct, and it’s a fine backup plan. But the cheapest and fastest option of all is a tow rope. A simple 20-25 mph tow on full regen will make an order of magnitude more progress than any emergency umbilical or plug-in.

Ever hear of a “tow truck”? I would just laugh at a Tesla driver who ran out of juice and keep going in my ICE car.

Holy Stupidity! – Get a Horse! ?
