As a new-ish owner, holy sh*t does that range get swallowed up quickly in the cold temps!
Yep. Same as for gas engines, but much more noticeable.
sure does. welcome to the 'hood
Warm up the car and battery while it is still plugged in. Also, the range and wh/mi differential is not all that different once the car and battery are warmed up. If you take it on a long trip (say, several hundred miles) range will be worse but probably not more than 10% worse. If you don't use the heater too liberally.
Seat warmers are much more efficient than warming up the cabin air, fyi. You may still need the regular heater on, but probably much lower.
Others have discussed at length, I’ll summarize:
• Schedule your charge to finish a little before you depart so you don’t waste electricity warming the battery twice
• Use the phone app to warm the car before you leave (while it is still plugged in!)
• Use more seat-heat, less cabin heat.
Range can come back as the car warms up. Especially if you have a snowflake on your display.
I drove the MS from NE to Rochester, MN last winter during the Polar Vortex. I parked it outside at night in Rochester for the week. When I left it on at a charger overnight and started it warming about 1/2 hour before driving it, there was little range hit. When I didn't leave it plugged in (another MS arrived and was using the charger), it definitely took a range hit.
Keep it plugged in and precondition it before leaving and you'll have no problem. For shorter trips, you won't have any trouble anyway.
My Wh/mile for my road trip this summer went around 300 Wh/mile or so when doing 65. With the relative cold of last weekend that was more like 360. That's with the car warmed and the heat fairly low (67), about a 20% increase and that's with the car warmed. I'm attributing it to the denser air (whether that's true or not I don't know) more than just the heat.
This is why one drives an 85, at least in the midwest. And tries not to look at the energy graph.
The denser air is for real; that's what a "polar high" is, and it increases air resistance.
