Re: Emergency Power Wiring Kit (for Nissan Leaf)

So, using the EVExtend, or one of the alternatives to hook up the 12V battery to the engine system battery, how many miles should I expect to get, assuming I have already totally exhausted the engine battery. BTW, how big is the system battery?

Your question makes no sense.
Please restate.

There is no engine.
There is a traction motor pack.
24 kWh but only ~21.5 kWh available when new.

The topic is about using that battery for other uses when electric power is out.
If the traction pack battery is fully empty, the LEAF will not move at all until you charge it back to above 7%.
And as I learned the other day the LEAF will likely deplete the 12V battery after the traction motor pack is empty.
My 12V was down around 7V and had to use jumper cables from ICE to even be able to charge the traction pack.

Allow me to restate. I believe that the purpose of the evextend is to use the 12V Battery as an emergency battery to get you extra miles too get you to a charging location. Assuming the 12V is fully charged, what is the extended range? What is the calculation?

No, the 12 volt battery cannot be used to power the vehicle. If it could, the distance would be measured in inches, not miles.

Wow, ok, then what is the purpose of EVExtend's kit?

The purpose of the EV Extend kit is to provide household 120v AC current for your home when the power is out. It will connect to (any) vehicle's 12volt DC power and step up the voltage for use outside of the vehicle. It wouldn't be used to propel, or charge an EV.

Correct.
In an ICE vehicle it will not last long.
But in a fully charged 21.5 kWH available for use LEAF it would keep your refrigerator cold and the air moving fan on your gas furnace working for a long time.
On a 48 kWH battery Gen 2 LEAF or Bolt or other electric vehicle it would last twice as long.
With a Tesla S you might muddle along for weeks without grid power.

True, the idea is to idle the ICE to supply long(er) term power to the inverter. My Toyota 4cyl will idle at .15 gallons per hour. Idled it for 2 weeks after Hurricane Ike. Just like the Leaf- needs the ignition on.

I am surprised it only burns .15 gallons per hour.

Have to be mighty careful about carbon monoxide poisoning idling an ICE or running a generator in proximity of a house.
Been quite a few people die doing that.

There is much more air movement between attached garages and homes than people recognize.
The vehicle or generator must be well away from the house with garage doors fully closed.

Good thing to keep in mind Tim.

I have done this in the past as well with our diesel VW Jetta, it consumes about .25 gallons an hour with a 1000w load and has a 120 amp alternator as well. I put it outside the 3rd stall nose in and ran the wire under the garage door.
