Real Wold BEV range reduction in a really cold region?

I would only add cold reduces tire pressure that increases rolling drag. Add air in the Fall and readjust in the Spring.

I apologize for being unclear.

The 60% loss was only starting with a cold soaked battery, then making a short (<5 miles) trip, then letting the battery cold soak, and repeating.
The 60% loss is not an issue as I wouldn’t have time to drive more than 30-40 miles in a day following that pattern.
Taking a long trip, the first 10 minutes will use the most energy, after that, the losses are much less.
If you are driving 120 miles, the loss would likely be closer to 25%.
If you were charging just before you departed, closer to 15-20%.

Over the entire winter, I average a 33% loss of efficiency. My winter driving is largely short trips.

There are some people that want BEVs to be difficult. They really are far simpler (at least Tesla’s are).
The range loss is predictable, just as the affect of driving habits is predictable in a Prius.

There is a learning curve, but it is a short one.

 

My wife and I put a deposit on one of each VinFast VF8 and VF9 pending which she prefers, most likely the prior. Great incentives I think today is the last day...

REVVL V+ 5G ?

 

what the mdsrp? incentives? everything i saw said prices coming

 

2013 Nissan Leaf SL (with heat pump) with 11 bar battery (only a couple months after loosing first bar).

With a 100% battery at the beginning, an attempted 70 mile trip ended before the halfway point of 30 miles with a dead battery. Mind you this was a trip we had made just fine all summer once or twice a week.

Temperature was -15°F at the time of driving (colder before that point)

Heater was only turned on every few minutes to clear the windshield. Heated front seats were turned all the way up. Both of us were freezing. I was going 45mph on a 65mph highway. When we hit an uphill grade the battery level dropped rapidly until the capacity bar was at the very bottom and the guess-o-meter flashed lines.

PS. There was no cell phone service where the Leaf died.
I also was expecting it to not make it, but it didn't make it as far as I had hoped. There also were no places to charge between the starting point and destination. Now there is one place, but only open in the summer.

 

Battery management is terribly important. ICE legacy engineers did not understand.

I’m glad you and your SO survived. How did you’ all deal with it?

I have a brother with a truck that knew where I was going. He came with a trailer before long.
