"GM to build new engine plant
 
Just what we need - a new plant to fabricate combustion engines. This whole thing is an investor relations ploy....
 
Good bye GM!

Companies build engine plants all the time. Better here than in China.
This is the plant that will be building the 1.4 for the Volt and Cruze.
 
Speaking of "investor relations ploy" there was a story that GM is planning to build Volt batteries in the U.S. using government setup money, of course.
 
IMO, this would be a good thing... otherwise we'd just be going from imported oil to imported batteries. They'd probably still have to import lithium, but I believe the largest producer is Australia, which is not an unfriendly nation.

The highest energy density of the Li-ion batteries being considered for EV applications right now is about 130 watt-hours per kilogram. So adding another 100 lbs of battery might get you an additional 6 kWh of stored energy or roughly 30 more miles. The Volt would now have a 70 mile range. I'm guessing this would add at least $3k to the price of the vehicle and that is a very optimistic guess.
 
If you had an EV with a 70 mile range would that be your only car? Unless you live in a retirement community the answer is probably no. So now you're in the situation where you have to own and maintain 2 vehicles, obviously more expensive. You will also use your EV less, resulting in less fuel savings. Any trip you now take of 70 miles (probably 60 miles) or more will be with your ICE powered vehicle meaning you will have sacrificed 70 electric miles that you could have taken advantage of with an EV that had an ICE range extender. Bottom line is that a person with an EV and an ICE vehicle for long trips will end up burning more gas and polluting more than a person driving an EV with an ICE range extender
 
Until we have affordable EVs with ranges of 200+ miles and a fast charge infrastructure the EV with a range extender is the most practical way to go and will result in the greatest fuel savings.
 
The RAV4 EV is probably the best EV application to date. It's battery pack weighed over 900 lbs and cost $27k to replace. As you stated it had a range of over 100 miles but I seriously doubt many RAV4 EV owners ever embarked on a trip this long. It would be a major inconvenience for your battery to die before you got home. So I suspect almost all RAV4 EV owners/leasees had another vehicle.

The two areas with the greatest Lithium reserves are in South America (either Chile or Bolivia) and China (the Tibet region). However up until recently Lithium really wasn't too valuable so there hasn't been a lot of exploration. So undoubtable other reserves will be discovered.
 
It wouldn't surprise me to see these batteries manufactured domestically. While costs are higher here than in China these battery packs will weigh several hundred pounds. So the expense of shipping them here won't be trivial. Also China doesn't have the greatest reputation right now for quality control. When you're talking about something that if manufactured improperly could potentially catch fire or explode that will be a major consideration. That's one reason that Toyota will be manufacturing all its battery packs in house. I don't know if these manufacturing plants will actually be in Japan but they will be Japanese owned and controlled.

Got my info from here:

Looks like the Aussies do have a lot of the stuff, along with the Chileans and others.
 
All preferable to buying Middle Eastern oil...

A new $42,000 electric mini SUV with 140 miles range by peralta

Just an assumption.
 
Would you be interested if say Infiniti would make an EV version Nissan Rogue with 140 miles range and only costs $42,000?
 
Put it in another way, how about a Lexus version of a RAV4 but EV with same 140 miles range for $42,000?

I'd be interested but that interest would be limited by the fact that I'd still need to own or rent another vehicle on occasion.
 
Let me ask you this. If you took this hypothetical Nissan Rogue EV with 140 mile range and added an ICE range extender to it would that make it a less appealing vehicle in your mind? If your answer is yes then basically you are saying that anyone making a trip over 140 miles needs to be using a strictly ICE powered vehicle.

I don't think any vehicle that does not provide a means of remote refuelling stands much of a chance of widespread acceptance, especially if there are range extended EV's available.
 
People don't like to chance being stranded, especially when the solution is a tow truck rather than simply fetching a gas can.

Here's a somewhat comprehensive survey / study about EV , especifically RAVEV
 
http://www.eaaev.org/Info/RAV4-EV_User_Experiences.pdf
 
This guy got an EVRAV4 and then gave up his pick up truck and Mercedes to get a second EVRAV4 (used and more expensive purchase), his third car is a prius that seldom sees the road.

Regarding your second link.
 
Why does this person own a Prius, actually 2 Priuses? If his RAV4 EV had a range extender would he still have a need to own a Prius? Also he describes taking 6 hour breaks on long trips in his RAV4 so that the batteries can re-charge. If you think this is a practice that the typical motorist will embrace then you are more than a little out of touch. BTW, a 27 kWh depleted battery pack, like in the RAV4 EV, will not recharge in 6 hours off a typical 110/120 volt outlet.
