Careful there, MarcG. You may give him an idea for a new app, at just the wrong time!
Will this app be able to give me a 1/2 hr log of charging levels? It would be helpful to know how long it takes to go from 90% to 100% when I'm range charging.
No. But you can figure this out by setting the charge limit to 90% then looking at the remaining charge time. Then setting it to 100% and then looking at the remaining time. At a supercharger, I think it's 20 minutes. But the last 1% is tricky, because it seems to take forever. I think there's some kind of exponential drop off point or something that makes it hard to charge the last few %. I think to truly complete 90 to 100%, it's about 40 minutes? Also depends on if your climate is on I think.
But for practical purposes the difference between 99% and 100% doesn't matter - if you are waiting to drive off there's no point waiting for 100%, or if you are concerned about having the charge finish during off-peak hours, the very low current drawn during balancing doesn't really matter if it carries over into a peak period.
I agree that the difference between having a 99% charge and a 100% charge won't make a practical difference with respect to your range. But the important point that you are ignoring here is that for people who don't charge to 100% often, the pack balancing is a benefit of that charge that they may want. Tesla advises to only range charge (100% charge) when necessary. So if I'm going to do something that I only do rarely, I want to make sure that if there is a benefit to doing it that goes along with the downside, I receive that benefit. By stopping a range charge at 99%, before the pack balancing completes, one would be getting most of whatever the negative effects of the 100% charge are, but missing out on the one positive one, or at least on some of the one positive one --a newly balanced pack. (And when I say "one positive one" I mean one in addition, of course to having a higher state of charge.)
Sure, but there's nothing that a mobile app can do to help. 100% charge to get the benefits of balancing is only feasible if you've got time to spare - it can take hours in the worst case, and the app has know way to predict it.
But for practical purposes the difference between 99% and 100% doesn't matter - if you are waiting to drive off there's no point waiting for 100%
