At the end of the day, the only "measurement" that really matters is that the distance the car can travel has been reduced to the point where the car is no longer useful as a primary commuter, and we are just lucky that we have a Prius and a motorcycle in the garage to augment our travel needs.Nubo wrote:Agreed. Knowing how much energy the batteries *are* storing does not necessarily tell us how much energy they still *might* be capable of storing, independently of the car's charging and reporting systems.dhanson865 wrote: TickTock compared wall, driving range, gids, bars, carwings, etcetera
wall - this is power in but if power used isn't the full range this doesn't tell us everything - see driving range
driving range - this could be limited by a software bug that shuts down the car before the battery is fully depleted. I'm not saying that is the case but it's the only thing I can see in the list that everything else relates to and OrientExpress is saying we should consider software issues.
gids, bars, carwings - these all go back to whatever software manages the bottom limit on driving range.
I think what Orient Express is saying so caustically is that short of pulling the battery pack out and testing it independent of the leaf's ECUs you are dealing with indirect data and can't be sure it is trustworthy.
But I also have to ask more to be able to defend TickTocks side here. How did you determine driving range? Did you drive until the turle mode stopped working and the leaf was dead and log odometer miles? Or are we talking some less extreme method of measuring drop in driving range?
I'm not in favor of his style of delivery but I think it is worth considering how many computers are inside a single car and how any possible firmware/software/signalling/measuring error could make things complicated.
I tried an 80% charge today. 4.5 miles/kWh got me ~41 miles to LBW. I won't be doing that again. 85% my a$$.
