I charged my car up because I wanted to do some EV cruising after supper. Before supper, however, I drove my car to pick up a pizza. This took two 0.2 mile trips (0.4 miles total). I plugged my car in after I got home, thinking I could 'top it off' but it didn't take any more charge. Maybe it still thinks it is close enough (13.3 - 0.4 = 12.9 = FULL)?
Interesting, that could be the case, but you'd think it would anyways. I'm sure Toyota has their reasons.
I'm still indicating 12.5 ev miles available after full charge. But maybe that's the low cholesterol diet interface not letting me go for pizza anymore, --- I am here: http://tapatalk.com/map.php?wpl4qe
Yeah. I wonder if that's some "undocumented" thing. Similar to the three gallon fill-up required for it to register. (Yes I know there's a difference between gasoline and electrons but I was just making an analogy.)
I'm sorry, but it might be operator error: When I went out cruising (after supper), it once again said I had the same 13.3 EV miles remaining... Could it have somehow gotten charged without me seeing the charge light on??? In any case, I squeezed 16.6 miles of EV out of it, just getting back into my garage with 0.1 miles of EV left (but I was 'hypermiling').
Your drop in battery charge was to small to start the charging cycle again. If you use a few miles of charge I'm sure it would let you charge again. I've tried the same thing.
I have never set out with the specific intension of getting the maxim EV miles I possibly could. For instance, tonight I had specific destination in mind (I wanted to try out the guidance system) and I wanted to see if I could make it there and back without using any gas. I once got EV 17.3 miles (my garage to my garage) but that was at night (so the headlights were on, wasting power). Sometime, when it really warms up in the summer (Minnesota) and there are more hours of daylight, I will try to do better.
Today, I found it interesting to note that, after driving 16.6 EV miles last night, my 'full charge' EV miles for this morning's commute only increased to 13.2 miles (an increase of 0.1 miles from my previous reading). I guess there really is a long history of averaging behind this estimate!
