Comment on Car dealers say they can’t sell EVs, tell Biden to slow their rollout

It sounds like you could’ve taken that car back for a warranty claim… depending on your state it should be able to do about 30 miles after either 8 or 15 years, and your was doing less than 20 at 9 years…

Having said that, draining the battery fully every day will absolutely kill it. It’s not good for the battery to be empty that often. If you get an EV with a 300 mile range and drive it 40 miles per day, charging every day, you probably would’ve go well over a million miles out of that battery.

This is the real reason I think high mileage batteries are important… I think most people don’t need 300 miles, but a battery that can do that can also be charged to 60% or 80% and charged before going below 20%, which should dramatically improve its life (saving the full capacity for the once in a while longer trips)

  Tesla recommends (and provides software) that limits charging to 80% and when they get to 20% they stop working to charge the battery and you’ll need to call a tow truck… unless there’s a major emergency/evacuation, then they will unlock the last 20% and allow drivers to use the whole thing.
  
  I don’t think the Volt did that. Maybe newer (and more expensive…) GM EVs do though.

    when they drain as low as 20% they shut down to protect the battery
    
    Haha what? No that is some serious misinformation. A Tesla might go into a slumber mode when parked for a while, this only means it takes a few seconds to start instead of the instant response if you parked for a short while. , but it will not shut down until sometime AFTER reaching 0%.
    
    Also, there are now two types of batteries for Tesla cars.
    
    The Tesla Model 3 RWD’s battery pack uses the LFP chemistry which Tesla recommends charging to 100% at least once per week. Tesla recommends setting the charge limit to 100% for daily use.
    
    The Tesla Model 3 Long Range and Performance variants uses a different chemistry referred to as NMC. The Tesla Model Y owner’s manual recommends setting the charge limit to 90% for daily use. This will minimise degradation and preserve the longevity of the battery.
