2170 battery life expectancy

edited November -1 in Model 3
Could the new 2170 battery greatly improve on the 18650's already great reliability? Interesting article at Electrek:

"If made into a car battery pack, 1,200 cycles would translate to roughly 300,000 miles (480,000 km) – meaning that a battery pack could still retain about 95% of its original energy capacity after ~300,000 miles – or 25 years at the average 12,000 miles per year."

    Present batteries may be like aging computers. An EV battery research claims that layering the battery rather than boxing it side-by-side could get 600 miles per charge. It will be tested in a car in 2020.

    Is this really that much of a stretch to what they do now? The Tesla loop cars still had about 94% of their original range after 200k miles even if the computer/software read differently. Maybe one of their other cars will break the 300k mile barrier next year and they can pull data from that.
    Those batteries though are not typical as they are almost exclusively supercharged every day which has been shown to add to the battery health despite warnings to the contrary.

    Ignore Eagle, supercharging has not proven to be detrimental to batteries. Eagles is spewing his usual trash.

    "But they didn't have any range left."
    Still batting 1000 I see.

    "Though the CAR DIDN'T ACTUALLY LOSE ANY RANGE, the estimator would say it could go another ten miles — and then power down"
    My emphasis

    E -
    Your reading comprehension is suspect. Please re-read the article. "Though the car didn’t actually lose any range" "Could go ANOTHER 10 miles".
    It shut down 10 miles before the software thought it was going to.
    This is vastly different than how you apparently read it.

    "But they didn't have any range left. As Tesla noted the software in the car was misreporting the battery state"

    What you fail to acknowledge is that when the car powered down when the estimator claimed it still had 10 miles of range, it had already gone over 200 miles.

    "But had the firmware been updated, we’d be fine and plugging along.”
    The reader unfamiliar with Eagles take on alt-facts is invited to read the original source material and make their own conclusion:

    Much like claiming that a car with a broken starter has a seized engine because it won't start - it doesn't really matter how the manufacturer chooses to fix it, the facts are the facts
  • edited May 2017
    "Could not be recharged" is a conclusion that doesn't appear to be borne out by anything resembling facts. Once again, I invite readers to review the original source material:

    Don't worry, MOST of us can read. In fact this is one of the articles that made me feel even more comfortable believing in the longevity of tesla batteries, and I'm sure there technology has advanced exponentially since the tesloop car was purchased.

    I can always accept some degradation over time, heck ICE engines get worse over time as well, losing gas mileage and horsepower. But the degradation of Tesla appears to be better than I had anticipated.

    @Ehninger1212. - "In fact this is one of the articles that made me feel even more comfortable believing in the longevity of tesla batteries"

    It is funny how Eagles posts are often counterproductive to his goals. For me also, I was originally leery about going with a BEV, concerned about battery life and replacement costs - but thanks to PDX, I have been steered to countless legitimate articles that have allayed these fears and make me very very comfortable with Tesla battery technology

    Thank you Eagles, for your repetitive false and disingenuous posts. (but if I were GM, I would take you off the payroll.)

    So you keep saying, and saying and saying like they will be true if only you can repeat them enough times as uickyl as possible.

    Wheres the evidence for ANY and ALL of those conclusions you keep saying is so?

    The Tesloop article cited above? Well none of those "Facts" you maintain as truths are contained in there.

    The Tesloop guy said:

    1. The range estimator was 10 miles short and stopped the car too early due to a (stated by Tesla) firmware issue not 'cos the batter was poked.
    2. The battery was still able to be charged, so clearly was not poked.
    3. If car wouldn't go when it was low on miles left in the battery it was because the firmware in the BMS errantly overrode the drive instructions from the driver, not 'cos the battery was poked or smoked.
    4. Tesla replaced the battery 'cos their firmware update was 3 months away for free and they probably didn't want to give Tesloop a loaner for 3 months - not because it had a warranty issue and Telsa wanted to simply STFU the customer, like say GM would.
    5. Tesla always does the right thing for its customers. Customer service - see thats what Telsa is about from the get go.
    6. No such statement were provided that Tesla only does the "bare minimum warranty" such as replacement of failed components, in fact Tesla went above and beyond, just because they wanted to, not because they were trying to STFU a customer.

    These are all evident facts, from the Tesloop acrticle.
    Completely unlike your futile "repeat after me with stuff I made up" trolling attempts which always come across as so ridiculous that no one believes you ever.

    Show some hard evidence for your conclusions.
    Or go away with your silly wankfest of self indulgence.

    "But they didn't have any range left"

    After 250 miles I wouldn't expect any.
    One time my gas gauge said I had about 1/16 of a tank left. I should have another 30 miles but I ran out. I should have asked the manufacturer to replace my engine.

    Eagles who?

    Though these "life expectancy" threads and ensuing theories still persist, no one with any authority says what is the considered the "end of life" for a battery pack? Often 70% of original miles is quoted, but I categorically don't agree with that. 70% of 265 is 185 miles. Well, that is still plenty of range to do a road trip, especially considering the ever increasing number of superchargers.

    "no one with any authority says what is the considered the "end of life" for a battery pack?"

    As far as the warranty is concerned, isn't it better than 80% of original capacity for 8 years or unlimited miles?

    jacknleela: No. Some here wish there were some sort of specific degradation number that Tesla would adhere to, but they do not, and personally I don't blame them. There is no need to publicize a given number as either an expectation of degradation or a guaranteed point of warranty replacement for a long range vehicle. It is far more critical for short range vehicles that couldn't have made half the distance between remote Superchargers even when new. But if a 70% charge is still enough to go 150+ miles, you are just fine in a Tesla that still has twice the range of compliance cars from traditional automobile manufacturers used as grocery getters. Don't worry about it.

    Red Sage, especially true as the Supercharger network and destination chargers become more ubiquitous.

    Some new Tesla battery news - future is bright for 2170 batteries.
  • edited May 2017
    A year ago, I was concerned about how to maximize battery life in my model 3. After all the study over the last year, i realize i just don't care-every thing indicates the batteries are going to last the life of the car, and as dyefrog noted more chargers make concern even less important. That said, i still want KPs better batteries...
