They'll have red and white electrons, the way we have red and white diesel just now.

The Leaf is 200kg lighter probably because it doesn't have an extra IC engine.

My next car won't be an EV. It'll probably be another little box with a 1.4 engine. But I like to think the one after that will be electric.

if i could afford the leaf or prius id buy one in second, but not in this crap economy.

Your diesel comment is funny! here on the better side of the pond we call it "Dyed Diesel" and you can get sooper dooper busted by johnny law if you use it in vehicals not for agricultural use.

When that leaf battery dies your stuck. The volt just starts up engine and recharges system.

Thank you Patrick for your SAE definition of a hybrid. For some reason GM makes a point to state this is not a hybrid. Only one mode of propulsion and thats the electric motors.

I agree with you that it matches the SAE definition for a hybrid.
Mabe they need to invent another word "electrohybridThingamajigy"

One more thing to add- The 1.4 is a temp. engine. They have a smaller engine but it wasnt ready for production. They are real hush hush about it but it could be some type of diesel.

watch out for government and corporate propaganda... those buzz words are how they propagandize.

and ill give you a seond example, trains are diesel electric too, just like the volt.

will the battery still work in cold winters, lets say -20 degrees C

I'm curious about this too. I live in Canada where it gets to be -20 for a month or two, I notice that my phone and MP3 player both run down faster in the cold weather. Cordless tool batteries don't perform very well either.

I bet that GM wants to differentiate themselves from the Prius since the Volt is much later to the game and I bet many consumers instantly think Prius when they hear "hybrid". Plus the distinction between the two types of hybrids is pretty important and many consumers probably wouldn't realize there is a difference if GM called the Volt a hybrid.

What is a temp. or a smalled engine?

I did some more reading on the Volt. (aka the Opel Ampera in Europe)

Low temperatures: GM say they tested it in Alaska. There may well be a heater for the battery to stop it getting too cold. It would probably warm up pretty quickly once you started driving.

Is it a hybrid: Wikipedia claims that there is a clutch allowing the IC engine to drive the wheels directly under some conditions.

Don't get me wrong, I'd love to own an EV for the geek factor. But my driving patterns wouldn't justify it. Also right now I live in a 4th floor apartment, there's nowhere to plug one in overnight!

When I was in China, it seemed like everyone had e-bikes. The battery packs were detachable, and people would take them off and plug them in anywhere they saw an outlet.

and to prevent people from stealing your battery pack

Haxor- The battery has two internal heaters which heat the coolant if temp gets to low. Even if car is off.
It also has an electric ac compressor which will turn on and cool battery.
It has a Dedicated cooling system not shared with the gasoline engine.

Edit for Radiotech : Charge station supplies a/c line voltage to the vehicle. The line voltage goes to an onboard battery charge where it is converted to ~360 for battery charging. No mention of current going back into house but that would be cool.

As far as charging another volt I would say no. All HV circuits are monitored for ground faults. We got to use a fluke DVOM during class that inputs 1000v into the cables for checking resistance of the insulation. This meter will bite you if your not carefull ;) FLUKE-1587 2 giga ohms!

Does the charging cable provide an AC or a DC current to the
vehicle? Your reply about the vehicle being in control of the time of
recharge is the reason for this this question.

IEEE recent articles on the evolving load/regulation problems in
areas where there are a lot of PV system grid inter ties mentioned
that vehicular batteries in a neighborhood (at night) could provide
peak demand boost capabilities, when the networks are integrated.

Could a Chevy Volt be a source of power to charge another Chevy
Volt?
