Using RAV4 batteries to power AC home?

[ferenc]

Hey, is there a system to use their EV DC batteries to run (part) of their AC home, say during power outages, or peak demand times?
It seems like a very nice solution to all kinds of problems,

PS For example, charge at night and dump back in day

Sure. Buy several Tesla PowerWalls.

Yea, but the energy is already in my EV batteries - I just need to tap them and a box to convert them to AC - no need for more batteries
Seems like such an obvious backup!

PS It also has 3x the capacity of the powerwall2 ...

For a RAV4 with JdeMO, it should be able to operate with the upcoming Nissan V2H unit.

Interesting - is the Nissan only Japan utility compatible?

The site you listed says, 'may work:'
13) Will JdeMO be able to power my house through the CHAdeMO plug?

Answer: Yes, it will be compatible with CHAdeMO specification 1.0, therefore with appropriate external equipment, it may work.

No JdeMO here,

Nissan is reportedly working on a cost reduced V2H unit for the North American market. That means that it will output 120V/240V split phase instead of the Japanese 100V/200V standard. I don't recall the exact spec, but the guy in charge of the project was at the Cupertino Drive Electric Week event this past September. I speculated that a 6kW unit should run about $2,500 and he said they were targeting a price well below that. He didn't say if they were targeting a power output well below mine too though.

Of course it "may" work... I have no idea what Nissan may produce. Once it is available, we will acquire one to test.

I need my car more than my A/C if the power goes out. Using the car does not seem like a viable back up.
Get the Power Wall and some solar to keep it charged.

You could also hook up a puresinewave inverter to the lead acid battery and hook up somethings while the rav4 ev is on. The dc to dc converter will top off the lead acid battery. I believe it gives no more than 1k watts.

100 amps.

wow would that be an inefficient way to get A/C...

DC Traction battery -> battery charger -> 12Volt -> inverter -> A/C

To keep the fridge and a few lights going in an emergency, it should be acceptable.

Not a bad idea, but that's only 1200 watts of power.
