It's a hidden reserve, read this topic I wrote about it. Near the bottom of the first page is where I post up my data. You can drive quite far on the 0% battery if you are gentle.Twigsandleaves said:That last item is the point that I'm interested in. I know highway miles in the cold are brutal so the efficiency isn't surprising, but if a 62kWh battery with 56kWh usable still has 9.1kWh left after driving the last 10 miles at "1%" how is that 1% actually 1%?
Average Economy - 2.8/kWh

dmacarthur said:Back-of-the envelope here: you drove 132 miles using 47 kWh of electricity. If you are paying $.15 per kWh for electricity, that trip cost you about $7 or about 2.2 gallons of gas equivalent. In terms of actual cost (which does NOT equate to environmental damage, but...) you are getting about the equivalent of 60 MPG. Depending on your per kWh costs this will go up or down.
Twigsandleaves said:Greetings, I'm asking this one before heading in for my first checkup on our 2021 Leaf SL Plus so I have a little more info and context to discuss when I get to the dealer a week from now.
Here's the scenario in question.
Brand new leaf, we just crossed 7000 miles the other day. The weather on the day was 35F, car was fully charged and cabin preheated with tires at 36psi cold. The wife has a conference 66miles away and takes the highway getting there with the battery reading 48% after that first 66miles (she isn't too thrilled with me sending her off to what looks like getting stranded on the way home, but I've driven it and read enough to know that isn't likely to be the case.) On the way back she gets home with 1% charge after driving the last 10 miles with all the low battery warnings scaring her to death.
When I check the Connect Ev app for the report at the end of the day I see:
Distance traveled - 132.5mi
Average Economy - 2.8/kWh
Electricity Consumption - 46.9kWh

I've been assuming this was just the manufacturer building in a huge buffer to scare people into charging well ahead of time to avoid getting stranded but it does seem a little excessive.
(I don't own a ODB dongle or Leaf Spy and honestly don't really want to, whatever you all have to offer is plenty.)
Thanks

Will be upgrading to an XL rated tire with a max pressure of 51 psi, which is how this car should have come from the factory given its weight and tire size spec. (XL in this case means "extra load" as opposed to SL or "standard load" tires. XL tires are rated to carry a given weight per tire for a given tire size at 41psi. SL tires are similarly rated, but at 35psi. XL tires allow a smaller tire to run on a heavier, or higher performing vehicle).
I'm curious, did you ever try out those XL rated tires? If so did you notice any change in your kw/mile #s (or anything else of note?)
