    I look forward to the day we can use our “dead” car battery as the battery backup for our home.

    64kWh * 0.8 is 51kWh.

    Even 40kWh would be a great battery paired to a solar system.

    The used car batteries could have great second lives.

      Hell, a car with 40 kWh of usable battery capacity is still plenty for a high schooler to get around town or something. Which is what you’d often expect for a car as it reaches an old enough age anyway

        Early Nissan Leafs started with 24 kWh, so when they lost a chunk of their initial range they became impractical to use. Your range might be shorter than the distance between chargers, especially in winter.

        If you start with 40 kWh, you can lose a third of that and it’s still fine for occasional long trips if you have charging network coverage. And you probably won’t lose a third of your battery capacity ever, since modern EVs have battery cooling and better batteries.

        LFP batteries will probably all outlive the cars they’re in.

          Those poor early leafs had no active cooling system for the batteries, being parked out in hot weather all day or doing heavy driving during the winter wasn’t so kind to their capacity either

          We have a slightly later leaf with ~30k but now it’s getting older the range is only about 80mi in warm weather (much worse in cold). It’s not really viable for distances, but we could hire an ICE for those rare occasions.

          Leafs are popular in southeast Alaska because there is nowhere to drive. They import used Leafs and use them as oversized golf carts.

      There’s already a company positioned to take “dead” ev batteries, referb them and put them into municipal power storage. I’d guess it’ll be the sort of situation where, if you can replace them yourself then the cells are yours to do with as you please, but if you go to a shop to have them replaced the shop will probably resell your cells.

    It’s almost like there is an AstroTurfed campaign to get people to lose confidence in electric vehicles by talking about batteries, even though most first generation Prius batteries are doing just fine.

    This is good news. Hopefully the percentage of damaged batteries (whether from improper production, wear and tear, or physical damage ) is low that they can continue to serve long lives. Hope to see more information on that soon.

    Trust me folks an EV is on everyone’s mind with gas prices like they are these days. Nobody can really afford either thing, amirite?

      I’ve recently started delivering for DoorDash and my mileage has skyrocketed. Im trying to figure out the cutoff where it makes sense to go finance an EV vs keep paying for gas. I don’t think I’m there yet, but I’m spending upwards of $200/month on gas so I’m not terribly far off from a used EV being the same monthly cost.

      “The good news is that your EV battery is far more complex and sophisticated than other lithium ion batteries in your life and is built to ensure its lifetime exceeds its warranty - and more.”

      Do you not know the difference between nickel -cadmium(NiCad), nickel metal hydroxide (NiMH) and lithium ion (Li-ion) batteries?

      Your rechargeable AAA batteries are almost certainly NiMH. Which is not what they use in vapes, phones, CREE flashlights and EVs.

      Downvote me to hell

      Toyota has made the right decision to go hydrogen tech !!!

      That V8 powerred by hydrogen make me moist

      Lol at those batt car limited range !!!

      Even Tesla misrepresented max range

      Gud

      Batteries EV car are damagable to environment ! Yea
