If Tony's JdeMO can also be programmed to close the contactors to gain access to the battery terminals, one could hook our 331Vdc battery pack to the input of a Sunny Boy Solar Inverter and get 240VAC ouptut to power the house for emergency use (provided it is wired correctly to disconnect when utility power is reestablished), or simply remote off-grid use.

How is a SunnyBoy going to work if there is no grid power? Also, what controls how much current is taken out of the battery? A SunnyBoy is designed to do solar Max Power Point Tracking. What we really need is a Sunny Island that can accept typical EV battery voltages of 300 to 400VDC instead of 48VDC nominal.

The new sunny boys have an emercency power unit:

The Secure Power Supply (SPS) feature provides up 1500 Watts of daytime power even in the event of a grid outage.

That is mostly useless as it is not going to power a refrigerator or any devices that have surge loads, it's designed for basic low current loads not powering much else. Sure if you need to use a laptop under full sun. The 1500 watt max rating is also for only certain types of devices so it is not very practical.

1500 Watts will charge your EV on level 1. I don't know about your refrigerator, but, my full size refrigerator uses about 1.5 kWh a day, if it runs 1/3 of the time that is less than 300 watts, nothing close to 1500 Watts.

It is not about consumption, it's about peak inrush loads like when the compressor first comes on. This set up is only for basic devices and can't do the same job a comparable generator of the same output is capable.

SPS is only good for things that can be plugged in by extension cord. It is not a solution that can take the place of a backup power generator that is wired into the house with a transfer switch, nor is it an on/off-grid solution. However, if you have a Sunny Island, it will communicate with the Sunny Boy and keep it running as if it was connected to the grid since the Sunny Island is providing the reference inverter. If the batteries are full and there is insufficient power demand, the Sunny Island will signal the Sunny Boy to curtail its production until the grid comes back online. As long as you have enough battery to make it through the night, the solar can recharge the batteries when the grid is down. However, Sunny Boy + Sunny Island + batteries is expensive.

Actually, Ideal Power has a 30kW bi-directional inverter that can take in DCV up to 500V (from either a battery pack, PV, or both separately) which would be, if they offered a 240VAC single phase output, pardon the pun, ideal.

They also have CHAdeMO plugs.

It's no surprise to many here that our JdeMO will be capable with V2grid/home, and a product like this is absolutley perfect except the output AC power. I did call them to see if that can't be fixed.

This port should be on the outside and dual use. It should also charge a 16+ kWh battery pack like the volt. This car should also have a j1772 port. Then the car would be an extended range EV like the volt, able to fill up for short trips at home with electricity and only need to fill with hydrogen every few months for most people. Try harder Toyota.

 

[miimura]

Agree 100%, but it's not going to happen. They're not going to put that much battery and a fuel cell in the same car. Too much volume and expense for that "extra stuff". If you think about Mirai, it's just an ugly Prius that you put Hydrogen in instead of gas. Same NiMH battery and everything.

5. Large external power supply system

The Mirai comes with a power supply system with a large capacity of approximately 60 kWh and maximum power supply capability of 9 kW for use during power outages, such as those following natural disasters. When a power supply unit (sold separately) is connected, it converts the DC power from the CHAdeMO power socket located inside the trunk to AC power and can power a vehicle-to-home system or a vehicle-to-load system. Consumer electronics can also be connected directly and used from the interior accessory socket (AC 100 V, 1,500 W).

For the record, they could have done all this with the RAV4 EV.

Toyota was looking rather promissing with the RAV4 EV and their investment in Tesla. Now it seems like they lost there way. Yes they could and should give their next gen RAV 4 EV the ability to fast charge and power a house out of the DC fast charge port that is on the outside of the car. Its like they haven't been to Japan, otherwise they would know that most people in Japan don't park their car in a garage so a power socket in the trunk would require keeping the trunk open to power the house during a storm. F-ing stupid design.

I agree it's stupid, but most urban Japanese don't have cars at all. In more suburban and rural areas, however, garages and covered carports are actually quite common. Either way, placing it in the trunk is a silly solution. Under the hood would have been better, but still not as good as being on the car's exterior.
