Hey Dan, I did "Switch <my> display to show battery % vs miles" which I liked but apparently "battery %" is the default setting so when I restart the vehicle, that's what it shows and I need to manually change it to miles.
Can I override the setting to be DEFAULT miles (not % battery and if I want to view % battery, I manually change the setting from miles to % battery?
Thank you
Bob
Nope. The only difference between percentage and miles is a scale factor (the EPA range rating). If you're more comfortable keeping it in miles and multiplying by some corrective factor less than one in your head, do that. For me, on the highway, I know I can comfortably go about 85% of what it says in miles before charging. Or, if you prefer multiplying by a number larger than one, you can keep it set to percentage. But you have to adjust the number in either case. Just set the display to your preferred value. Changing the scale is assuredly not losing information, and saying that it is causes Claude Shannon to spin in his grave.No, this is objectively false. With a percentage display, you are seeing percentage of …. what? Do you know how many usable kWh are in your battery at full charge? I don’t think so. Plus, even if you did, this number changes over time as the battery degrades. So how does knowing a percentage of an unknown value translate to “energy available“ (your words)?
Conversely, mileage display is directly proportional to energy. No, one rated mile (which has nothing to do with environmental conditions nor how the car is driven) does not directly indicate how many real world miles you will get . But it does tell you energy available. Just multiply rated miles times the EPA factor for your car (2021 Y LR is 270wh/mile IIRC) and that is how much energy is available. Simple.
When you switch to percentage, you are deliberately throwing out information (energy available).
If you actually need to know how far you can get, because, say, you're going to Canyon de Chelly and the superchargers are far and few between and the NPS still hasn't installed L2 chargers at the visitor center, you don't want to be using that display at all. Use the Energy graph; it takes actual current conditions into account, and gives a much more accurate estimate.
