I concede to your knowledge on things mechanical & electrical. I am not just picking on hybrids as the direction of all cars is toward short years and high mileage. Those of us that do not drive a lot are stuck with all the little problems that age will bring out in vehicles. It seems to me that most of the problems with be sensors and computer modules. The engines seem to be built to last longer than ever. And of course the batteries aging will be a big concern especially with Li-Ion. I am not as skeptical of the NiMH batteries as I have used them in laptops for 7 years without dying.
 
So I imagine the battery debate will go on for some time. My advice is to those so unfortunate as to have a long commute. A hybrid can be a good choice. For me that will let a car sit for a month or more without driving it, hybrids are nothing but additional problems.

That's a very nicely written and well-balanced post, as are your others on the HSD subject. Thanks for the insider expertise.

I want to charge my battery with my solar panel by kwatts59

I have a 12volt solar panel and I want to use it to charge my Prius car battery. I want to use less gasoline and rely on solar electric power. Is it possible?

The only battery you can charge with that solar panel is the small battery that keeps things ready to go. It would be advantageous if you leave your car idle for weeks at a time. Otherwise it will do nothing to save gas.

I was just wondering because I keep my car in the sun all the time, I dont park in a garage or covered parking. I also live in the desert in southern Nevada, the sunniest state in America. I just wanted to know if I can save a couple of miles per gallon. Every little bit helps.

The battery that you would need to charge to give you better mileage is the traction battery. It is a high voltage NiMH battery. There is no user access to that battery. You would void your warranty by trying to add anything to that system. The 12 volt battery is strictly for keeping the onboard computer active. It has nothing to do with the drive train. If you were to convert to a plug in Hybrid you could add a solar charging system and then you would save both gas and electricity. It looks like there will be some plug in hybrid options in 2010. That would be your best option.

houdini1 says, "You are conveniently forgetting that at 8 years you have to replace the batteries in the Prius at a cost of $8,000. That adds up to $1,000 cost per year."
 
This statement is very misleading to the uninitiated. Allow me to point out the problems with it so that not one person is confused by the reality:
 
1. If you live in a CARB state, the warranty is 10 yrs/150K miles.
 
2. No one in HISTORY has paid $8,000 for a Prius battery replacement. It has not and will not ever happen. The cost is far less than that, and it rarely if ever is paid ENTIRELY by the consumer.
 
3. There is no guarantee that a Prius owner will EVER have to replace a traction battery, and in particular there is no reason to believe that the ENTIRE battery system will fail and need replacement. Replacements such as that are VERY VERY rare. So rare, in fact, that it is difficult to even find a story about it happening that can withstand fact-checking and scrutiny.
 
4. I know of no one in a CARB state who has posted that the Prius battery failed outside of warranty. Not one instance of the current generation Prius having a battery replacement outside of warranty has been reported, as far as I can find.
 
5. The cost of replacing a Prius battery is no different than having to pay for replacing an engine in a similar car. And everyone knows that people pay for replaced engines SO OFTEN these days !!!!!!
 
So - is there a RISK of the Prius having a problem after 8-12 years of ownership in which a battery replacement will have to be paid for by the owner of the car? Of course there is a risk of that.
 
But it is not any more likely than a Malibu blowing an engine after 8-12 years. At least as far as ACTUAL CASES have gone.
 
There are even very few cases of the original Prius (first sold in the USA almost exactly 8 years ago now) needing a replacement battery. Those stories can be found but are also VERY VERY rare.
 
Prices for used Prius batteries—which come from junkyards and auto body shops—range from $450 to $1,700, says Famous Rhodes, director of eBay Motors parts and accessories.
 
Similarly, Toyota's Prius battery is down to $3,000 from $5,500.
 
The good news, though, is that the chances of needing to replace the battery in your hybrid is low, even after the warranty coverage is up. Honda says that less than 200 of its hybrid batteries have failed post-warranty, despite over 100,000 vehicles on the road. How about Toyota? Its post-warranty battery replacement rate sits at just 0.003 percent.
 
Modern hybrid vehicles are designed to minimize the strain on their high-power batteries. Battery management systems have been programmed to only allow a certain amount of the battery's available charge to dissipate, which greatly extends the life of the unit. So, when considering a hybrid vehicle, perhaps the battery shouldn't be too much of a deterrent.

The poster to whom you replied has rarely made any posts with accurate info concerning the hybrids. He continues to refuse to do any research and verify if his misconception has any basis in reality.
 
But in the limited circle to which he's responding it plays well, it doesn't matter whether it's true or not. "The Yanks are gonna take it all again this year", says one Bronx bar patron to the others... "Yeah you said it!" comes back the reply.

The question is HOW LONG would you have to wait for a replacement battery on the rare occasion that one fails. If there is a shortage as Toyota says, how many spares are in the USA waiting that possible failure? Same goes for the first gen batteries? Or will the unlucky Prius owner have to wait until the new factory is built?

How many angels will fit on the head of a pin.
 
Both points are so are far from the realm of reality that the answer just doesn't matter. The occurances are so rare that when and if one does ever happen, just like your Sequoia, and a customer is put out of a vehicle by a warranty issue there is replacement transportation - of equal type - available at one of the TRAC outlets.
