I took the challenge by fellow pioneer Tom Moloughney (#250) to try and drive my 90 mile commute while using the heater (previously I made the drive comfortably, albeit on the cold side).
I’m happy to report that I completed the task yesterday:
– 85 miles total* (not my usual 90 mile commute, I had to go into NYC – enjoyed a heated garage during the day)
– Used the heat 5 times (2 on the way in, 3 on the way out) for approx. 6-8 minutes each time
– Heat was in the middle dial, fan was set at 2 (also middle dial)
– I made it home with 2% on the SOC meter (State of Charge)
– Battery temperature never got below 55°
– Ambient air temp was between 24° – 38°
In the summer and spring I was regularly making 90 miles, showing 8-15% SOC at the end of the day. So the results here show that heater use does have a significant tax on the batteries (~10% with fairly conservative use).
