It is pretty well known that winter temperatures hit EVs pretty hard when it comes to range. It's not clear to me how much it impacts charging. I'm not talking about charging currents since level 2 charging at home never rises to a point that it is limited really. I'm talking about how much charging is needed to drive the same miles in winter temps.
I know regen has some impact, but that should be fairly minimal unless you do a lot of stop and go driving. If the driving is mostly at highway speeds and conditions, 50 to 70 mph and no stop and go, what is the source of the reduced range? Is it that more energy is needed to travel the same miles because of the motor, tires or something else in the driveline? Is it that the battery becomes less efficient in returning the energy that was stored in it? Does the capacity of the battery drop so you can't get as many kWh into it in the first place? Does the battery not receive current as efficiently so it takes more energy to charge it up?
