Seem to be in line with inflation for other autos. "The only reason I can see for the lighter batteries is less capacity." less capacity...The reason is for less weight or more capacity is the reson for lighter batteries. "I have not seen any credible evidence that the price of batteries for the hybrids have come down at all since their introduction." callign toyota dealerships through out the years there was been a remarketable delcine in batery costs. At first the cost wasd about 8-10 grand to replace the batteries, now its about 3-4 grand to replace the battery. "There may have been some subtle advances." those subtle advances have increase battery performance by 20% sinse they days of the EV 2. many of those subtle advances have led to lighter batteries.

Replying to: gagrice (Feb 26, 2007 10:32 am) CalCars has promised a PHEV Prius conversion for some time. Is it available to the consumer as of today? If so what is the cost? Im not talking about Calcars. I was talking about replacing the orginal manufacurer equipment. I priced it about 3-5 grand. What does a gas sensing guage computer have to to battery costs? Which have been going down. Lithiun Ion battery tech is getting very old. The cost to replace the Lithium Ion battery is dropping. The new nanotechnology batteries which are very expensive. like all technology , as it matures, it become cheaper. esp when production kicks in. It costs to push the technology envelope. its cheap to rehash the some ol technology. Its cheap for auto companies to make a new full size p-u. Its expensive to make a hybrid.

Replying to: timinalaska (Jun 27, 2006 1:03 pm) I would be happy to just get the mileage stated by the factory or even 3/4 of it, certainly I expect to get more than half the specified mileage! |

Replying to: gagrice (Feb 26, 2007 1:54 pm) seven years ago people were stating batteries were costing 8 grand to 10 grand to replace. I was born at night,..but not last night. According to Toyota, the cost to replace the battery is $3,000 and lets throw in another 2,000 for labor...so 5 grand. and lets throw in another grand, so one can feel cheated and taken advantaged of by the stealership. Thats a new Prius battery and 3,000 for labor to install a battery. http://www.toyota.com/html/hybridsynergyview/2006/fall/battery.html So if the price for a battery significantly differs from Toyota's pice, one should call Toyota and tell em. Toyota designed the Prius to have easy to replace parts. They realized that auto mechanics are not eletrical engineers and the prius was design with that in mind. " They have two very bad characteristics. They can combust if over charged and they have a relatively short lifespan. These are big obstacles to the 100 MPG hybrid." Many batteries will explode if overcharged. A plain jane car battery will combust if its jumped the wrong way. Im sure the people at calcars have some type of state of charge computer built into their system. I know the Prius does have a state of charge computer in to promote battery life and overcrahrging and undercrarging. This is old technology and one doe not need to revinvent the wheel everytime a new ev or hybrid car comes out.

Replying to: shalwechat (Feb 28, 2007 11:10 am) True, but the question is - does this same battery life technology also work on LiIon? They are notoriously bad on longevity in laptops. One of the characteristics I found in my Dell is that occasionally it had to be discharged almost fully, or battery use-life would suffer. Also, that battey is now dead; I find LiIon is good for about full 500 cycles. I would be interested to hear from someone who has information on LiIon vs NiMh characteristics in this area.

Replying to: stevedebi (Feb 28, 2007 12:54 pm) To be practical the PHEV will need a storage system that can use more than 60% of the capacity, as the Toyota hybrids do. |

Replying to: shalwechat (Feb 28, 2007 11:10 am) I do not think they have overcome the problems inherent in Li-Ion batteries to the point they will be used by Toyota to build a PHEV. That 100 MPG Prius was a gimmick car sent to Great Britain to get those folks interested in hybrids. It is not an easy sell where there are many choices of fuel efficient cars. This is discussion of PHEV so I will add this from your link. Q: Is this the kind of battery that would be used if a plug-in hybrid system is developed? GS: A system like that might use nickel-metal hydride or lithium ion batteries. Plug-in systems need significantly more capacity than currently exists in the batteries in our hybrids. Toyota is exploring the possibilities for plug-in hybrids, but has made no determination about them. Q: What about the third-party suppliers who are converting Prius and some other hybrids to plug-in use? GS: Toyota's current hybrids are not designed for larger traction batteries, and the company discourages these modifications, which void the vehicle's warranty. The conversions that I'm aware of are very costly, add significant weight to the vehicle, and have not gone through the rigors of full engineering evaluation such as brake balance, crash testing and durability. |
