Forecasting range

[MarkC]

Has anyone been able to find an independent app that monitors battery conditions, forecasts available range independent of the GOM, provides useful can/OBDII data, etc, etc. Having owned 2 Nissan Leafs for almost 7 years, the LeafSpy Pro app has been invaluable in understanding how to predict range under most user conditions based on actual experience of your particular situation. It monitors battery conditions so that you can tell if particular "cells" are causing issues AND shows how it is degrading over time. Much useful (nerdy?) information also.

It appears from posts about GOM/range "surprises", that something similar would be very useful to reduce "range anxiety" - especially when used for towing time after time.

I find that nothing short of simply paying attention to your 'Miles per KWH' calculation is going to help you 'forecast' your long-range miles available, and even then, the miles ahead of you can also impact that either way...
historically, if you average something like 2.5m/kwh, then use that as your starting assumption, expecting, though, that negative conditions can bring that down, as you travel.
My battery pack is 'roughly' 100kwh, so at 2.5m/kwh, I 'assume' at the start that I could possibly drive as much as 250 miles, to 'totally empty'.... although I will never PLAN to drive that far, but it's a good starting point to planning the travel day. Stopping to fast charge between 200 and 225 miles is probably a good plan.

One of the great features of the app I mentioned is the ability to:

1. At any battery SOC, input the best estimate of miles/kWh for remaining trip
2. Input a minimum % battery SOC you are willing to accept
3. Output the remaining estimated miles

Even the latest Leaf's GOM does not allow such important variables to be inputted, that results in sometimes a highly accurate remaining miles, but often, when most needed, does a really cr**** job.
