"Looks like a 25 to 50% loss of battery life"Looks like a 25 to 50% loss of battery life. In a nissan leaf, this puts you into the 50 mile or less range from what I understand. If you have a Tesla, which has a much beefier battery your range is much more, but still depleted.
I read an article that said the greater concern for EV drivers in the severe cold was not the reduced range but the loss of power when charging. Apparently the grid is lost quite frequently in those cold storms.
But that all being said, Doesn't -25C gel diesel? Then I realized you wrote C, no F. What first world cities get -25C on a regular basis? Just asking.
Being a greenie I guess (well, earth conscious maybe?) I am less concerned about cars and the polution. New gas engines are really dropping the emission levels to next to nothing. And as I noted before the diesel electric might just be the stop gap for new car manufacturing until someone truly makes a decent battery.
I think power generation is the real issue now. Coal has got to go. Same with Fracking. But also, the US has to get tough on other countries that don't step up to the clean air plate and by that virtue can produce product at a much lower rate.
I presume you mean "decrease in range". Battery life is related to how many times it can be charged, not how far a single charge will get you.
The drop is a combination of using more electricity (heater use, higher rolling resistance of winter tires, driving through snow) and battery "capacity" at cold temperatures.
"What first world cities get -25C on a regular basis? Just asking. "
You are kidding right? -25C is only -13F. Barely cold enough for snow to squeak when you walk on it. LOTS of the USA regularly gets that cold (and much colder) Dec through Feb. Regular #2 diesel will start to gel around 32F. The distributors fix that for you by adding kerosene. LOTS of kerosene when it is REALLY cold
ALL vehicles suffer lower MPG (and therefore range) in cold weather. You will see that if you regularly (as in EVERY fill) track your miles driven/gallons added to fill (and ALWAYS fill). Thing is, a 10% to 20% drop in a 20 MPG vehicle is not nearly as noticeable (as a number) as a 10% - 20% drop in a 50 MPG vehicle. You drop 4 MPG, I drop 10 MPG. Similarly, running snow tires will bring down the MPG of ANY vehicle as will A/C; heat brings it down in hybrids and EVs. You can preheat a Leaf's cabin while it is plugged in at home though that will only get you so far before the onboard heat has to kick in.
With regard to loss of power during storms, yes that is a problem in some areas. We have 2 electric companies on our 2.5 mile long road. The end with one company lost power several times last winter, our end never did. Go figure. But that is something to consider. People who lose power frequently probably have a generator. If they decide on an EV, I guess they need a bigger generator to handle the outages unless they don't need to go anywhere.
