Cold weather driving can reduce electric car range over 40 percent, AAA study finds.

Discussion in 'General' started by Ceetee, Feb 7, 2019.

  1. To add while the technical data that leads here or there, is interesting and provided certainly as well in the AAA study itself, I think it will have little application to the subject in this context.
    It will serve only to confuse the issue. I suggest staying with the easily understood perameters I have outlined.
    We must consider the audience and application of survey results the context they survive in.
    You expressing how many giagwhat abouts we loose as per your ananamomotermeter, may serve to show your qualification well but little serve this discussion. To be clear I am not intending to insult you but to display that will not serve purpose with humor employed. You doing that, certainly you will not. Point is most of us uneducated to it(to include myself) will take data as goblygook, unreadable, We stop immediately looking at it.
    The simple stuff reporters are good at. And keeping it simple is about the half of it. We must not fool ourselves most reading here are not engineers but fans.
    You are real world older vehicle it the definer of this....so what you say? Please keep the tech side out of it.
    To be clear by gauges I mean car gauges, what one may find in the car and look at, not technical gauges one may personally own.

    Two points here: Inside EVs encourages members to write in about their experiences and this is what we do sometimes. This is a young technology and we're all learning and helping each other about how it works in the real world. Secondly I couldn't agree with you more about how some media will grab something like this and blow it all out of proportion.

    My first experience with range loss with my previous Leaf was on a round trip run that I was making easily in warmer temps, usually arriving back home with 15 to 20% charge left. I thought it would be safe one day to make the run when it was just a few degrees above freezing. About 8km from home to charge indicator was down to 0, the range was just a flashing line and the car was talking to me. I made it home and the turtle never appeared but what a nail biter.

    EV range is all over the place depending on driving style, wind direction, temperature, change in elevation etc. well you know all that. Members sharing their experience is not a scientific survey with hard data but if it prevents someone from making the mistake of buying an under capacity BEV facing the worst case range scenario then it's all good. The prospect of getting stranded in the cold and dark is not going to encourage EV adoption and I think most would agree on that.
     
  3. Well thanks Paul appreciate the response. I hold personal bias against Nissan having owned a new one, though not a EV and having to unload it within the year due to reliability issues.
    But you may find this interesting. Came across this on the Kona EV site here(other members content) I think it is, which of course would reflect new technology response to cold as there are brand spanking new..
    "
    So I've left my EV parked and unused for the last week, didn't really want to bother taking it in the snow yet. I've been monitoring the battery levels and the range, so at least I can update everyone on that. In one week of no driving and minimal starting, maybe 2-3 times at most, battery dropped to 85% (from 86) and range dropped to 387km (from 388), not bad at all!! Now if I start driving it I wonder if it will decrease faster, that's for another day."
    Another poster
    "I went on vacation and left my Kona in my cold garage for 15 days. Just checked and battery was only down from 100% to 99%. I am impresssd."

    Judging by these comments, there may indeed be a disconnect between the older battery technology and the brand new ones as I read it.
    Which would directly read again into the question of why only older technology was tested by AAA and used vehicles employed.
