The ELR uses the exact same Voltec drive train, batteries, engine that the Volt uses. It even uses the same platform. The ELR just has a different body shape and interior. So is fundamentally identical to the Volt.

Not true.
My Volt is giving me 47 miles range right now in Orlando - typical daytime temp right now is about 98F. 47 miles is exceeding the GM estimated max range. Volt batteries do not have problems in high temperatures.
And fires? and losing 20-30%. Seriously. No. You really need to read up on these things before you make these types of statements.

I know of at least 1 company who offers a monthly rate for unlimited charging. They will install a charger at your home and they also have a network of charging stations that are available to customers. Right now just in TX and CA but planning for growth.
Others have a pay as you go system charging you by the KW for the power. Thet have a credit card swipe or an account number with pin. Since its new a lot of places are offering free charging. For instance a number of NFL stadiums installed chargers linked up to their solar panels which are free to use. As more people get electric vehicles that may change.
Here is the government report on the fire
http://www.nhtsa.gov/About+NHTSA/Pr...ent+on+Conclusion+of+Chevy+Volt+Investigation
"NHTSA remains unaware of any real-world crashes that have resulted in a battery-related fire involving the Chevy Volt or any other electric vehicle. "
There is a charging overhead, but it is not that high. And regardless of the overhead, it is still much cheaper to operate a Volt than any gas powered car.
Just to clarify this 20%-30% loss thing...This happens to a certain degree with any battery you charge. You cell phone, rechargeable AA's, car, whatever. The act of recharging is basically reversing the chemical process in a batter that produces electricity. I do not know of a single instance where the transfer is 100%.
This efficiency is not limited to charging either. It is estimated that on average only 14%-21% of the energy in a gallon of gas is actually used to propel your car down the street.
Now I have no idea if the energy loss for charging a Volt is 20%-30%, but pointing out that there is energy lost when charging a battery as a negative is like pointing out that water is wet.

Electons do not like to move fast in cold weather...
Actually I think electrons don't mind, but the chemical reaction is the issue. That's what they taught us in electronics way back when. Anyone still put there batteries in the fridge for long term storage?

What type of battery is it? I could google it but you already know, so I figure it's easier to let you tell me.

Not that this would be a problem in FL.
from http://batteryuniversity.com/learn/article/lithium_ion_safety_concerns
A major concern arises if static electricity or a faulty charger has destroyed the battery's protection circuit. Such damage can permanently fuse the solid-state switches in an ON position without the user knowing. A battery with a faulty protection circuit may function normally but does not provide protection against abuse. Another safety issue is cold temperature charging. Consumer grade lithium-ion batteries cannot be charged below 0°C (32°F). Although the packs appear to be charging normally, plating of metallic lithium occurs on the anode while on a sub-freezing charge. The plating is permanent and cannot be removed. If done repeatedly, such damage can compromise the safety of the pack. The battery will become more vulnerable to failure if subjected to impact, crush or high rate charging.

Passive safeguards for single-cell batteries and active safeguards for multi-cell batteries (such as those used in electric vehicles) have been designed to mitigate or prevent some failures. However, major challenges in performance and safety still exist, including the thermal stability of active materials within the battery at high temperatures and the occurrence of
internal short circuits that may lead to thermal runaway.
As part of the product development process, manufacturers should conduct a risk assessment that might involve tools such as failure modes and effects analysis and fault tree analysis. UL employs these tools to generate root cause analyses that lead to the definition of safety tests for product safety standards.
But what does UL know?

The argument of fires in EV cars is just bizarre. Are you suggesting there are no fires in gas powered cars, and that we should be specifically concerned about fire in EVs, even though the US government testing lab has NEVER had a report of a real world EV fire?
A lot of this reads as some kind of desperate attempt to hate on EV vehicles which I do not understand. How about being proud that a US company is leading the way on this technology?

AWESOMNESS!!!!

Lesson? Don't do stupid things with li-on batteries or they will not play nice with you.

The overhead on the Volt charger is something like 15% when charging at 110v, so similar to what you report with gas.
Am I correct in assuming that quick charging is higher?
So do I post this in response that nonsense above. The fire argument is pointless, so I am going to leave you to it.

Yeah yeah but I used to play with conventional and nuclear weapons. So I see your gasoline and raise you a mushroom cloud.
USAF Aircraft Armament Systems Specialist!!!! YEAH BABY!!! When it absolutely positively needs to be removed from the face of the earth. Or Nuke em till the dust in the air glows! 462's 2W1's forever!!!!!

HUH WHAT?
I wasn't arguing? Just posting videos. Loosen up that tin foil, and no that is not a black helicopter.
A little enriched uranium does go a long way. Governments due tend to get upset when you start playing with it though.Yeah yeah but I used to play with convention and nuclear weapons. So I see your gasoline and raise you a mushroom cloud.

Seriously check it out. And yes I have purchased from them.
looking for some uranium? http://unitednuclear.com/
