  • I know the resistive heater in my Volt can’t compare to the heat put out by the ICE.

    the ICE generates an insane amount of excess waste heat as a byproduct, so you have a virtually unlimited supply. The Volt is a PHEV so resistive heating was probably not considered super important.

    If the heat pump can put out more heat for less energy

    There’s no if about it, it is ~300% more efficient.

    That might be the second biggest issue (next to range)

    They are the same issue. Less energy used for heating = more range.


  • Lots of people consider only their commute

    No they don’t.

    The frequency of 200+ mile trips is vastly overestimated by anti-EV people

    The frequency is irrelevant. Again, if you want to go on a single trip, literally ever, in the entire time you ever own that vehicle, it needs to be able to make that trip, and it needs to be able to do it in a reasonable about of time.

    A half-dead 2011 Leaf would still cover my 40-mile round trip.

    If you only ever drive back and forth to work, then I feel really really sorry for you, but you are an extreme minority in that sense.









  • Most people aren’t road tripping in their electric vehicle every day.

    They can’t road trip ever if the vehicle doesn’t have sufficient range. I don’t understand how you can even be in this conversation when you don’t understand basic principles like this.

    If you don’t understand how temperature affects battery chemistry, capacity, and charging

    I understand how it affects all of these. It doesn’t cause any of it to “not charge properly”. EVs are used in the coldest places in the world with no major charging problems.



  • The average commute is 52 miles. Most EVs sold in the US have a range of 250 miles or more.

    No one cares about “average commute” when buying an electric car and considering the offered range. They’re thinking about long trips.

    So a resistive heater eating 10% of your range is way less of an issue than your battery not charging properly in cold weather.

    Who said anything about batteries “not charging properly”? What does that even mean?

    heat pumps should be available, but they aren’t going to save you if cold weather kills your battery.

    We’re not talking about killing batteries, we’re talking about electric range. Heat pumps extend your electric range and 20 miles can absolutely be the difference between making it to the next charger or not.



  • This is effectively a startup, as Sony doesn’t yet have any of the infrastructure needed to manufacture these. Tesla started out with $100k+ cars as well.

    As for legacy automakers? Well they don’t make cheap anything anymore. Just giant trucks and SUVs.

    You can buy a Nissan Leaf for <$30k but I would not recommend it at all until they add some sort of active cooling to their batteries. They’re an absolute joke without it. But it is a valid demonstration that it is possible.



  • the logical thing to do is whatever gets the most people on the site the fastest, not do something that instantly alienates a massive amount of people

    Not true. Facebook knows no one is leaving (at least not in any significant numbers). So what makes them money is showing ads. What allows them to show more ads is people staying on the site longer. What keeps people on the site longer is “engagement”. The easiest way to keep people “engaged” is to sow discord.

    Just think about it, are you more inclined to comment on an image of a cute puppy, or a post where someone is spreading disinformation?
