Toyota Mirai – CHAdeMO in the trunk

As we already know, the Toyota Mirai hydrogen fuel cell car will come on the market (at least in Japan) with an optional power take off (PTO) device that enables it to serve as a mobile generator in case of emergency.

The PTO will be connected to the CHAdeMO inlet in the trunk and will turn the DC current to alternating current, edible by other appliances.

Nichicon Corporation, with its 6 kW EVPower Station – used by Nissan and Mitsubishi – will work with Mirai too as an emergency power supply to power building equipment and home electronics.

Toyota is making Toyota Home Co. responsible for introduction of the product:

“To ensure EVPS functionality and quality, Toyota Home Co., Ltd. (HQ: Nagoya, Aichi Prefecture; President: Tadashi Yamashina) will handle EVPS sales, installation and after-sales support to customers with “MIRAI” vehicles.”

In the case of Mirai, the CHAdeMO inlet can’t be used for charging the battery pack.

Not to put people out of business, but why can’t GM follow suit with the Volt? Provide a PTO port with a good 10kW, and you have a solid backup generator for your house or camp.

Mark Hovis

+1 Brian, should be standard or an option on every range extender equipped EV. Just like the Mirai, they all are functioning essentially as a generator.

George Bower

Just hook an inverter across your 12V battery.
It’s a lot cheaper.

Brian

Yeah, it’s been done, but there is no way you’re going to get 10kW out of that setup. 2kW max. Enough for essentials in an emergency, but far from enough to run a house.

John in AA

For that matter I want a way to take power out of a Tesla. 85kWh is several days worth of power consumption for my house.

Tony Williams

There’s no reason we can’t do that now with our JdeMO on a Model S.

You would need an auto-transfer switch at your circuit breaker box, and an inverter that we are developing for 2016.

You could also charge your Model S at CHAdeMO stations.

David Murray

Indeed. I think PHEV products and even standard hybrids like the Prius should have a factory option with some sort of high-power inverter that runs off of the high voltage system. Give us a couple of 120V sockets at least, maybe a 240V. I bet a lot of people would be willing to pay as much as $1,000 for a factory option like that. I bet you’d even get some preppers to buy hybrids then!

Speculawyer

I don’t trust the typical American to use such a product properly.

Lad

Right you are especially when it has a hydrogen cylinder with 10,000 pounds of pressure in it; “It’s the bomb”…a real bomb.

I am really interested in taking power in and out of my Leaf. Is there a company that sells an “EVpower station” or “leaf to Home” system in Australia?

Eric Cote

There are the EV Extend kits that I sell, but since that goes through the 12V battery, power is limited to 1000W/2000W surge.

I have sold some kits to Australians.

Like Brian suggested above, I’m a bigger fan of a larger option if the automakers would produce it. 10kW is a breeze for these batteries.

Jay Donnaway

Hey Nichion- we want a version of the EVPS for the USA! An unsubsidized JDM price of $6k is steep, but some would sell.

The charging capability should be a full 7.2 kW to match the backup power capability, not a lame “less than 6 kW”. The high output version should at least be capable of DC charging the car at a similar rate to it’s AC inverter output capability of 14.4 kW.

Jay Donnaway

Oh, and Hey Toyota. The subject matter of these comments should help you gauge interest in the Mirai. EVen if the car turns out to not be a mirage, there’s no interest in automotive fool cells here. You’re either pursuing a foolish technology for consumer vehicles, or gambling on some very expensive smoke and mirrors.

It is interesting and neat . . . but it is a pretty niche feature.

Pretty much zero homes would have the necessary input to connect to it. And even if you actually did have it or get it installed . . . I don’t know if I want the typical American idiot responsible for turning off their main power, hooking this up, and using it properly.

Idiots would probably forget to turn off their main switch and thus electrify the grid that repairmen are trying to work on. Or they would leave too many loads turned on such that it would not work properly when trying to power their fridge, hot water heater, space heater, stove, etc.

Brian

Many “idiot Americans” have properly installed full-house backup power generators. When done right, the user CAN be an idiot, because power cannot flow back to the grid. In rural areas, it is quite common for most / all houses to have a diesel backup generator. A bad ice storm can take out power to a remote area for weeks at a time. Even if that happens once a decade, people will invest in backup generators.

All I am saying is that I would like to see a way to use one’s car instead of a generator. The wiring in the house could be identical – idiot proof. The connections to transfer power from a Volt instead of a generator would probably cost less than a 10-20kW generator and fuel tank system. It’s a win-win!

ModernMarvelFan

Agreed, it should be an option at least…

Today, you can do some forms of that inefficiently by turning on the Volt and leave it in standby and then tap power of the 12V through an inverter. When the car is on, the main battery will charge the 12V and then eventually the engine will start to do the same.

It is power limited though.

Speculawyer

I trust those rural people who have dealt with this type thing much more than the typical American suburban dweller.

I think the big point is that we lack the idiot-proof system of connecting the car to the house and thus it doesn’t matter if the car can output current if the home can’t accept it.

See Through

Well.. at least you can power a few critical items with a generator extension cord. Don’t just connect to the grid. Connect those items ( refrigeratirs, some lights, computers, wireless router, tv..) to its output.

Brian

And my point is that one could simply hire an electrician who is competent enough to do it correctly. You know, the same way they hired an electrician to install their EVSE. I really don’t think it’s as horrific as you’re making it out to be.

And I’m not comparing this to the small portable generators with 120V and/or 240V outlets on them. I’m talking about large stationary generators that are hardwired into the home’s electrical system.

Doug

How would this differ from the average idiot American using a gas powered generator to the same thing? And why do you assume the Americans have a lock on idioticy? Really?

Speculawyer

A typical gas-powered generator has a few outlets on it. The idiot will realize that he can only plug a few things into it. And it generally does not connect to the grid.

But if we have something that plugs into the house, it had better be build to be idiot proof because people will do stupid things.

I do not think Americans have a lock on idiocy. It is quite a world-wide phenomenon. I do think it has got a bit worse over time. People used to know how to change their oil and change a flat tire . . . these days it seems most people can’t even do those trivial things.

“. . . when trying to power their fridge, hot water heater, space heater, stove, etc.”

Apparently, you’re an idiot. Hot water heater? Hot water doesn’t need heating. ;D

ModernMarvelFan

I think we have a culture barrier.

In N.A. or US, the hot water heaters are usually mean the water heater in the house that we use for hot showers or hot waters that come out of the faucet…

Taser54

Welcome back. How are the UFOs?

MrEnergyCzar

I run my full sized fridge and Pellet stove with my Volt when the power goes out… most have higher energy needs though…

Whatever

What are you supposed to do with a 100 volt output? I guess it could be used to charge a stranded EV

Djoni

Yes 100 volts but with two phases, so it’s 200 volts 50/60 hz @ 30 amps from phase to phase.
Except we need more like 120/240 volts 60 hz in north america, so this is probably for other country, Japan or Australia?
Anyway, the good thing is that if mass produced, this appliance could be used by anything that has a CHADEMO and that any Nissan EV product that you choose to take this feature and it’s a lot more than Mirai will ever be.

Sivad

At least the Mirai is useful for something.

kdawg

For the price of the Mirai, you could install quite a few home generators and still buy a plug-in car.

QCO

Great. So after using all the fuel to power the house, the car will have to be towed to the nearest hydrogen station (which is likely to be far away).

It would be much more interesting if it could run on the domestic natural gas supply, maybe plugging into the BBQ outlet using a hose.

ModernMarvelFan

That is the same problem with BEVs used as backup…

I guess PHEV is the only way to go. 2 sources of energy…
