I'm very interested in the future possibilities for electric vehicles but I've got more questions (concerns) than answers. Range is one of my big concerns. I would want a range of at least 450 miles even in the most extreme conditions - bitter cold of winter and extreme heat in the summer. Temperature variances no doubt affect range but by how much. Also, what is the battery replacement life and can I expect the same range after 3, 5, or 10 years of repeated recharging? And then there is initial cost to purchase. Electric vehicles are currently cost prohibitive to most buyers.
Range should be the bigger concern ... but become less of one as the charging infrastructure continues to further develop. The picture is very similar as it relates to battery replacement too ... once there are more refurbished batteries available, the prices will get driven down.
I got one of the earlier short-ranged Tesla Model 3s ... love the car. Where I live, electricity is relatively cheap ... particularly compared to fossil-fuels. The car price was comparable to that of a combustion-engine Subaru.
I have a bad lower-back ... so I need to take breaks while driving anyhow ... so charging the Tesla at super charger stations works like a charm. However, I can understand how folks who like to "power through trips" might find the added breaks a little annoying.
As others have mentioned, the understated big advantage of all-electric cars is the lack of need for maintenance. Pretty much the only thing you need to worry about is changing tires. My car makes such little use of its disk brakes that the only reason to pump the brakes is to prevent them from falling entirely into disuse. I would surmise that I won't need brakes changed for the entire life of the car.
For folks used to combustion engines, it might be odd to think that there is no need for any fluids other than windshield-wiper fluid.
As for your question about range - cold weather arguable has the greatest impact on range because the battery actually needs to be somewhat warm in order for the chemistry to supply the appropriate EMF. If you drive before the battery is adequately warm, then the regenerative braking doesn't work (as well) because the chemistry is rate-limited (by the cold-battery).
If it's hot out and you crank the AC ... then yes, you can bleed through range pretty fast that way too. However, in that context, you don't have to "pay the overhead" for a warm battery. Of course, there is the inverse "cost" of preventing the battery from overheating. However, if you're in a pinch, you can open your windows to help preserve a bit more range.
