Recharge Your Nissan LEAF Via CHAdeMO Outlet On Toyota Mirai Fuel Cell Sedan

Thanks To Toyota, LEAF Owners Now Have One More Way To Charge Theirs EVs

Thanks To Toyota, LEAF Owners Now Have One More Way To Charge Theirs EVs – Is That A Smile Or A Smirk?

All we need now is the proper cord, right?

“What’s more, thanks to fuel cell technology’s versatility and adaptability, the Mirai offers performance options that go well beyond a traditional automobile. In fact, the vehicle will be offered with an optional power take off (PTO) device that enables Mirai to serve as a mobile generator in case of emergency. With the PTO accessory, Mirai is capable of powering home essentials in an average house for up to a week in an emergency – while emitting only water in the process.”

States Toyota of its fuel-cell Mirai, but why stop there?

Let’s put this optional power take off to use for the benefit of pure electric vehicles.

As we previously pointed out:

Toyota seems to have some cooperation with Honda in this matter, as both companies stated capability of supplying up to 9 kW DC power from the car (via CHAdeMO) to the external inverter (an optional power take off (PTO) device), which will turn it to AC and enable the car to power electrical appliances or maybe even a whole house.

But we don’t need to turn it into AC if we’re using that juice to recharge a LEAF (or any other CHAdeMO-capable EV).

“With a full tank of hydrogen, Mirai should be able to provide approx. 60 kWh of energy so you could survive (with a working fridge) a few more days than others when the zombie apocalypse strikes.”

Or more than enough to fully recharge a Nissan LEAF.

We’ve finally found the Mirai’s true calling: rescue service for the occasionally stranded BEV.

Look for the Mirai fuel cell sedan to enter EV rescue service fleets as soon as it launches in December 2015.  It’s a lucrative business and Mirai is perfectly suited for the task.  Toyota’s free hydrogen deal is a plus too.

The problem is that the Leaf’s battery charging voltage is about 400V, while this thing is designed to supply an inverter that gives 100V/200V AC. It really depends on if this port and the DC-DC converter behind (assuming it has one) even supports 400V output.

So they found a use for a fuel cell car? 😉

MikeM

Finally! Vindication for H2 mobility.
I always knew it would be good for something!

John Hollenberg

First good use of a fuel cell car I have seen… nice find.

No chance there will ever be a Toyota fuel cell in my garage.

Using two staples to attach the velcro tabs to keep the outer cover on, tells me this outlet isn’t intended to be used often…

Mmm, quality.

kdawg

If they had done anything more then it would have become expensive.. oh wait?

Rob

Yeah, they should have glued the Velcro on…

9kW charging. About 30 mph. Seems like pretty long roadside assistance turnaround time. I’d rather have Andromeda’s Heather Lin roll up with a 50kW ORCA and give me a quick charge.

At $500/month and $4-$12/kg for H2 FCV and Hydrogen, Andromeda’s solution is cheaper too. The car is better looking too.

Depending on the rescue driver, 30 mins may not be enough time.

David Murray

Any PHEV could offer a similar capability using the gas generator, yet I’ve never seen any production car offer it.

Not quite as simple as that. Do you think you could connect a full Leaf to an empty Leaf with a double ended Chademo cable and have everything work out nicely? Unless the Mirai was able to output the varying voltage and amperage required by the Leaf as it charges up, you’ll need a box in between doing some DC to DC conversion at 9kW.

Joshua Burstyn

Agreed. There’d be no initial handshake AFAIK, nor would 9kW be all that awesome. (You can get up to 43kW AC charging anyways?)

protomech

Since the LEAF can also act as a PTO device, it presumably supports bidirectional communication for power.

kdawg

But who rescues the Mirai when it runs out of hydrogen? It’s not like you can walk and get a 5-gallon jug of it.

See Through

Hydrogen tankers, silly! A 5 minute fill-up to 100%.

protomech

I guess tankers probably don’t have a supply connector or the correct PSI to supply vehicles, only the refueling center tanks.

And the only thing more ridiculous than sending a diesel-burning tow truck to rescue a stranded BEV is sending a H2 tanker to rescue a stranded FCEV.

Rob

Well, once you’ve charged up the Leaf, it can tow you to the garage.
Classic case of ‘you scratch my back…’ 🙂

Even if this is possible, it isn’t very practical. The Mirai can’t go more than 150 miles from the nearest hydrogen fueling station. And if you use it to charge the Leaf, then you are transferring range from one car to the other, with some loss due to inefficiencies.

As much as Toyota talks about range anxiety with electric cars, it will be a far larger problem with fuel cells. It is trivial to put a 3kw generator in a car to rescue an EV, but you can’t transport hydrogen around easily. You also only need to get the EV to the nearest usable outlet, while the Mirai has to get to one of the dozen refueling stations.

Basically, this doesn’t make sense because the Mirai has more range restrictions than an EV. So if the EV got stranded somewhere, it is unlikely that a Mirai could get there to rescue it. Unless the EV owner is being deliberately stupid about managing their charge.

Brian

A few good observations have been made about the transportability of hydrogen. One of the complaints about batteries is that you cannot fill a 5-gallon jug with “electrons” and carry it to your BEV. If you can’t do this with hydrogen either, then you lose a major fall-back. AAA already has some demo trucks with quick chargers for stranded EVs. What are they going to do for FCVs?

Brian Henderson
Has the capability been stated by Toyota, or is the ability to “Recharge Your Nissan LEAF Via CHAdeMO Outlet On Toyota Mirai Fuel Cell Sedan” totally made up? While the CHAdeMO standard supports charging using voltages from 50-500V, there is NO indication of what voltage the Mirai is able to supply. A LEAF requires a the charging voltage between ~380-400V. Further CHAdeMO has two sets of communication protocols: 1) a battery controller requesting specific power from a charger, 2) an external grid inverter requesting DC connection directly to the battery pack (the inverter convers DC to AC) The problem with a direct connection between a Miria and a LEAF is neither has a DC-to-DC controller to regulate voltage level and manage current. There is no safety concerns as without a controller neither vehicle will connect it’s energy source to it’s CHAdeMO port. ie: nothing will happen. An anology is plugging a mic directly to a set of speakers without an audio amp that adjusts the signal and voltage levels. For the Miria to supply power it needs a 1) external PowerBox to generate 120/220V AC from DC or 2) a DC-to-DC controller to manage current flow between two high-power sources.… Read more »
