Apparently, the 2014 rav ev has some issues, that are NOT tesla's. So, one of the tesla guys told me that Toyota is in talks with Tesla about getting access to their current tech (the rav 4 is using roadster tech, not Model S), which would include the SC.

no. li-ion batteries have 3 main issues:
1) Overcharging will kill them.
2) high power drains.
3) most of all, HEAT. Heat is the bane of li-ion batteries.
With tesla, they avoid all 3 issues. With nissan, they suffer at least 2 of the issues.
For example, both probably keep the overcharging down. However, the leaf is far more likely to suffer from overcharging. The reason is the few numbers of cells that they use that must undergo large amounts of charging. Basically, the leaf has 192 cells, of which they pull and charge from all of the cells in parallel.
OTOH, the Model S has 7000 cells in the Model S 85 KWH pack. What they do not do, is pull from a set of cells at a time, until they are drained down to a certain level, and then go to another set of cells. As such, when you are charging the tesla for nighttime from your average 40-70 miles, you will only charge a fraction of the cells. Now, another issue is the heat, and this is a big one. Nissan thinks that putting all of the cells in a closed box and then air cooling the box will work for when charging. Nothing could be further from the truth. BTW, you will notice that Nissan is re-formulating their chemistry to handle those high temps. And if you look through my postings from several years ago, I spoke about the fact that I would never want to own a leaf in the south esp. in AZ, southern CA.
OTOH, Model S has cells that are basically AA size, with each one fully monitored and each one individually liquid cooled. That means that each cells is pampered.
2 minutes? I doubt it. Secondly.
The super chargers are here and being built out NOW. It is no different than gas stations in the 60s when I was growing up, since gas stations were NOT everywhere.
And in 2 years, when gas is 5/gal, please let us know how you feel about the rest of us getting free energy for xing the nation.
keep in mind that wicker is one of those that actually opposes private space, and fully supports the SLS. He has worked hard to kill less than 2B TOTAL of funding for private space, while pushing to spend 3B / year on the SLS and spending more than 2B for flights to the ISS via russia, which is the same nation that he regularly blasts. And if it was not for SpaceX and Blue origin, then this tower would be totally useless.
the leaf's that I see are never parked in a simple lot. They are always plugged in. That indicates that ppl are concerned about range. And when the leaf has 1 million+ cars out there, it will NOT be inconsequential for all of this charging.
Also, I note that you speak of 80+ miles/day, but the fact is, that most ppl will think about distance, not about total miles. As such, we are talking 40 miles away. After that, it needs a charge.
As I said, this is over all a good second car for a family esp. on the east coast. I would never use it for the for the primary in the west, and certainly think carefully about it as a second in California (things are really spread out).
If you believe that they have the exact same problems, then you must be claiming that diesel fuel has the same problems as gasoline and that a Chevy blazer will have the same issues as a ford explorer. Yes?
that is LEAF's, not tesla. Two very different cars and battery chemistry. As I wrote up elsewhere, Nissan does not handle their heat, and their chemistry is known to not like fast charging. Tesla's battery chem is different and they handle the heat properly.
nice thing about W's admin is that he changed laws that implemented mercury controls to 2016. Combine that, with nat gas cheap prices and utilities are walking away from coal plants (cheaper to switch to nat gas, then to add more pollution control).
So, coal is now 35% and going down.
Here is 2012.
you do the numbers, BUT, you do not factually point out that coal is only 35% of our electricity or that 28% is nat gas and that less than 1% is fuel oil. IOW, you need to lower those first 2 figures to around 1/3 of what they are and kill off the last (or.95 gallons).
exactly. Nissan does not handle the heat correctly, and their chemistry DOES mean that fast charging is NOT good. BUT, you are right that it is nothing like what the original poster wrote.
Turns out that fast charges does NOT wear out the batteries. What wears them out is doing a fast charge all the way to the end while allowing heat to build up. So, tesla is the ONLY company that handles the heat of the batteries correctly. In addition, when super charging, it can do 50% charge in 20 minutes, and the other 50% in 40 minutes. The reason is that it after it is half full in the cell, it slows it way down so it does NOT burn out the cell. And if you charge 100% of the time at a supercharger, the tesla batteries will last the same as if you charge on a 110.
First off, Model S/X are expensive, but that is about to change in 3 years.
Secondly, Next years Toyota rav ev can make use of the superchargers.
Third, super charging does NOT destroy the batteries. They have already proven that is the case.
Fourth, having a charger every 100 miles does not mean that you must use it, any more than you must use a gas stations that runs block to block. Fifth, super charging is less than 1 hour to charge the model S from drained. And most sites have 6 slots, not 2. You can use google map to look right down on it and see how many slots, or simply read it straight off the page.
I agree with you about the long trip and using EVs for regular local trips. In fact, I view the leaf as a good MOM type vehicle. Still, I have issues with the constant daytime charging.
There is no speculation in my posts. Go read Musk's twitters.
As to our not owning an electric, we are waiting for the Model X. Once it comes out, then my wife will decide which one she wants (she wants a crossover; I think that Model S is good enough).
I have done the leaf and have seen the others. Sorry, but they are not worth the money. In my mind, electric cars should not have any real subsidy until it has at least a 150 MPC. Without that, you encourage not just loads of range anxiety, BUT, most of the small MPC vehicles will charge in the daytime. By doing that, you will add to the costs of electricity by requiring more power and grid.
BUT, EVs that get 150+MPC, will actually LOWER electric costs. The reason is that almost all of the time, they will charge at night time.
That is also why I believe that we need to change our subsidies on evs and hybrids. Basically, offer up $5K for all general hybrid and EVs that have less than 100 MPC, while offering 10K for EVs with 100-149 MPC and gas/diesel serial hybrids, and then $15K for any vehicles that is 150+MPC EV, or a natural gas serial hybrid (these can be converted to regular electric as energy density increases in batteries, caps, etc ).
you are right. There is more to life than work. However, how many ppl drive their car more than 250 miles/day constantly? Few. VERY few. And within 2 years, Tesla will have a supercharger every 100 miles in the USA, so that you do not have to worry about that.
Tesla has a number of adaptors that allow it to use the other chargers. It is true that the others can not use superchargers, but tesla can use the others.
Just not with Tesla. Look, if you are in a leaf, you get 75 MPC. And that is without any extra energy use. That limits you to city driving. Worse, there were few fast chargers in the cities. Now, because of Tesla, Nissan is installing CHadmo chargers at all of their dealers. But a 75 MPC, means that you can really only go about 35 miles away, which makes the leaf a close car, nothing more, without access to decent chargers.
BUT, a tesla with a range of 250 MPC, well, none of those owners suffer from range anxiety. In fact, if you read what they post, they find this better than gas cars, because they can simply plug in at night time, and get a full charge each and every single night. Not even a gas car is that good, without taking a 10 minute stop at a gas station.
The car has a 250 MPC range. The average for an ICE car is 250-350 (with most of it at the low end). As such, this is very similar to a regular car.
In addition, within 2 years, America will have a free supercharger every 100 miles or so. In addition, they will in about 2 years, start adding battery swaps at those locations that will allow you to not only swap out your battery for a fully charged one (and only in 90 seconds), BUT, the new temp battery will have a range of 400-500 MPC.
So, please explain why you need anything else?
why? These cars do 250 miles. And they have access to a free supercharger every 100 miles or so (or will in 2 years). 250-300 miles is the current range of about 75% of all ICE passenger cars. So, tesla is currently average. Why should they add an extender?

And as proof of the situation, the roadsters that have 100,000 miles already, none had more than 19% loss. They are varying between 12-19% loss. And that is with the OLD formula that is not supposed to be as good as what is in the model S. There was ONE roadster that with 149K miles, was down to 50% levels, but he is the only one. It is possible that he abused his car since he is the ONLY one with this issue.
2 minutes? I doubt it.

I would suggest that YOU grow a brain.

no vehicle suits 100% of ppl. Few vehicles will work in the back county of the rockies.
I can't be completely sure how Tesla's batteries work since I don't have the proprietary info on their specific characteristics. However, most batteries are harmfully affected by only 3 things: overcharging, deep discharge, and high temperatures. This means you can charge them at nearly any speed as long as you keep them cool (Tesla's thermal management), don't overcharge them (presumably intelligence in the battery management system), and don't discharge them too low (up to the user). Presumably, if sensors in the battery detect that the pack is getting too warm, the supercharging will slow down to protect the battery pack. While I can't be 100% sure Tesla is doing this, they're pretty smart so it is very likely that supercharging won't have any adverse affect on the battery life - ever.

I agree that I don't think there is a problem with the Tesla batteries. We have nearly 60,000 miles on our Roadster that is over 4 years old and we have minimal noticeable range loss. It has driven and charged in temperatures well over 100F many times. It did, however, limit the charging current below the 40 amps available when it needed to, in order to protect the battery.
A field test engineer told me their test cars were filled over and over with a supercharger during trials, and no measurable change occurred. He was awestruck.
that is LEAF's, not tesla. Two very different cars and battery chemistry. As I wrote up elsewhere, Nissan does not handle their heat, and their chemistry is known to not like fast charging. Tesla's battery chem is different and they handle the heat properly.

I agree with you about the long trip and using EVs for regular local trips. In fact, I view the leaf as a good MOM type vehicle. Still, I have issues with the constant daytime charging.
This is a map of the superchargers that are currently in the USA, as well as those that are under construction. Do a 250 mile range to see where you can drive your model S today. Do a 100 mile range to see where the next super chargers will be built.
In addition, you can see the coverage that Tesla is planning here. Advance the time on the map to see where the build out will be at the end of 2015.

no. They BORROWED AND PAID BACK 450 million in gov money. And will have a 35K EV in 3 years and a $20K EV by 2020.
