> the Prius has a much smaller battery

Indeed, the Prius has a smaller NiMh battery but the system still keeps its SOC within predefined bounds at all times (40%-80%). Anyways, I just didn't feel comfortable with doing it based on how it acted afterwards.

> Or do you think I need to go with an inverter and power supply?

It would be more efficient and cheaper to get a second iCharger.

Prius plug in's are Li Ion

I have the PriusC and I would love a high amp 12v line from the batt.

They are large enough, as long as you start with what shows as a full charge, you should be more then fine without any degredation.

hi just want to ring in here with the icharger running on 12v u wont get it to charge past 18amp or some where around that. u must have input of 20v or more to get it up to 30amp output. i learned that the hard way. good luck though sounds like a great idea

Even if you hook up to the 12V battery inside the vehicle, if you make an extension lead to run outside the vehicle for charging, you will be limited to the wire and connectors to do so. ALSO YOU MUST FUSE IT!!! Otherwise if you do have a short (like a car crash) you will watch you car burn to the ground.
That being said, I used 0 AWG wire for a setup I tried a while ago, worked great but I was also using the battery in my car. Good for a couple of quick charges but that is about it (non-hybrid)
Good luck!!!

....The Volt has a large 360V 16Kwh Li battery....
I would not want to tax my Volt battery for anything other than driving the car. All batteries have a definite life span.....A Volt battery will cost at least a few thousand to replace. It may be a lot cheaper in the long run to use a Honda generator for the models.

One potentially negative aspect of doing this is adding discharge/charge cycles to your vehicles battery which could be espensive in the long run.Stupidity can be cured. Ignorance is for life!

Seriously?! That Volt battery isn't going to even know it's being used to charge such a small load.

I also have a Volt and looked into this. First of all it is an amazing piece of technology and everyone should be excited and proud that an American company created it.

From what I can remember you have the possibility of 2 charging solutions. First you could charge from the smaller 12v battery in the trunk. When the car is running in electric mode I believe it constantly charges the 12v battery so it should never be discharged low enough to hurt it. There is also a set of terminals in the trunk that go directly to the voltage "stepdown". This is what charges the 12v battery and goes directly to the lithium battery. I have charged a few times on mine and the car doesn't act any different. Charging a 6s5000 pack twice at 3c didn't even affect the range.

As far as the Volt's lithium battery, it has an 8 year warranty. It is currently listed as a $3500 part per several GM mechanics. One thing GM did was limit the max disharge. It is currently limited to about 50-60%. Once it hits that cutoff the ICE engine automatically turns on to generate electricity. Only after the battery ages and the capacity drops will it access the remaining capacity (per GM's tech documents). Another interesting tidbit I recently learned was that if the car runs out of gas and the battery is discharged it will give you an extra 2 miles on battery power to get you to a gas station.

The best part though....in 2700 miles I have used 20 gallons of gas, of which 9.5 were used on a roadtrip home.

GScott,

Thanks for the info, I'll try charging it from the 12V this Spring. Quick question: did you hook the charger directly to the 12V source without going thru an inverter/DC power supply conversion?

I've only driven it 200 miles so far and I can honestly say I've never had a driving experience that is more fun.

The Volt is truly a technological marvel, which has unfortunately been subject to too many misconceptions and political attacks.
