Real world results of battery testing, maintenance + costs over all gen's of Prius & others!
Needless to say, I was surprised at how well the Honda hybrid battery held up in the Insight compared to the Prius battery. Founded in 2003, PriusChat has been the go-to spot for Prius, hybrid, and EV discussion for over 10 years. Website Phone Arena has conducted a test battery of newer devices, and in this test the latest smartphone from Samsung, Samsung Galaxy S5, has shown excellent results.
The Nissan LEAF, which launched in the US back in December 2010, was touted as a breakthrough electric vehicle, but many automotive enthusiasts immediately expressed concerns over Nissan's decision to deploy a lithium-ion powered vehicle without liquid cooling.
Liquid cooling controls the temps of the battery pack more precisely than air cooling and, by doing so, limits battery degradation.
An exhaustive test, recently conducted by InsideEVs Tony Williams, seems to prove that either air cooling or Nissan's battery chemistry is inadequate.
This should be a wakeup call for consumers to demand battery range minimums in their warranties. Extended range electrics are going to have to rescue the momentum and lead the way for EVs, it appears. I've read about different types of lithium batteries and LiMn2O4 are known for their capacity loss when overheating. My 2011 Tucson-based LEAF has 7700 miles on it; it now also has a solid 11 bars of battery capacity.
There is no doubt this has to be addressed, or it will be another huge financial risk of owning an EV. Two things -- I'm pretty sure that the Nissan Leaf's battery pack is passively cooled, and does not have any fans in it.
I am compelled to say that in temperate climates, such as Bay Area, things are just peacock feathers wonderful. On the other hand, I do look forward to 2013 and what innvation that I don't know about yet is coming (i.e. If Hitachi's ad hype is true, this is supposed to yield a longer-lasting battery with greater power density.

I was also surprised to read from one of Tony William's posts (tis true, Neil) that the current production Nissan pack doesn't have ANY cooling fans and relies on a semi vacuum packing of sort sort, basically to protect it from excessive moisture. Could Nissan's new battery be a unit with Hitachi cells and cooling fans similar to what was found in the prototype Leaf packs?
Getting back to LiFePO4s, the ones that seem to be the most robust in high heat situations are the new (not generally available until early 2013) A123 EXT units . The generally favorable asset to these is the ability to charge more quickly than other lithium formulas.
I know a lot of folks here are very excited to see what will become of the Envia units, which are promised to be only a few years off.
World2Steven: so sorry to hear that you are now in the "eleven bar club." Are you going try to make it down to the Arizona Inn this Sunday? Needless to say, after the above SOMETHING electric is going to be around for the (my) duration.
If I had a Leaf and lived in a hot climate (the latter already true,) and the car was losing battery capacity fast, would I consider a replacement battery with slight less energy density (translate to slight less range) but almost guaranteed never to deplete further? Micheal: You'd answer your own question if you'd read the previous paragraph to the one you quoted.
If you plan to charge in public, you'll want to sign up for charging network membership (or two).
How do you ensure that electric car owners will be happy with every visit to your charging spot?

Samsung Galaxy S5 first appeared in similar tests at the end of last month, where it hinted that the device has a high performance battery. A couple of years ago, people were basically ho-hum about LiFePO4, because the power density is slightly lower than other lithium formulas. I think I read somewhere that Hitachi is the vendor Nissan will go with for the 2013 Tennessee-assembled Leafs.

If I lost a bar or 2 I'd be taking matters into my own hands and call A123 or Envia asking for assistance, begging them to put their hardware in my semi-disabled Leaf and embarass Nissan.
Let's hypothetically say that Nissan will only honor factory battery pack replacements on just some of the current generation Leafs. There are also no internal combustion engines, tires, computers, toaster ovens or track shoes that won't wear out eventually.
We hope you'll join our home to educated & critical discussion, falling outside of the fray of Internet trolls & unconstructive discussion. I have this feeling I'll be selling and buying a Leaf next year depending on what's in the hopper. A fraction of a volt or amp per individual cell doesn't sound like much, but it adds up when you've got hundreds of cells in a car-sized pack.
Whoever is going to make the pack, it's already claimed to have more range than the old one. The vehicles with older, stock batteries will always be suspect in the eyes of consumers (possibly to be picked up at pennies on the dollar used) and would be a prime candidate for an aftermarket upgrade. Samsung Galaxy S5 battery test showed that it can be compared with the tablet devices, and surpassed the results of phablet devices with a battery of 3000mAh or higher.
Currently, the following states regulate the offer and sale of franchises: California, Hawaii, Illinois, Indiana, Maryland, Michigan, Minnesota, New York, North Dakota, Oregon, Rhode Island, South Dakota, Virginia, Washington, and Wisconsin.
Before the battery depletion issue became such a hot topic (pun intended,) I think range was the only thing both manufacturer and customer was really concerned about. If you are a resident of, or wish to acquire a franchise for a [Matco Tools distributorship] to be located in, one of these states or a country whose laws regulate the offer and sale of franchises, we will not offer you a franchise unless and until we have complied with applicable pre-sale registration and disclosure requirements in your jurisdiction. Now, of course, people are clamoring for more range AND some assurance of greater long term reliability in a high heat environment.
