6 years later .. 34,000 miles never quick charged and still get 100% battery charge and avg over 70 miles.
I see that the leaf cars getting only 80% of the original battery life after only 2 years.
Why spend an extra 10gs on a car that will lose battery life in such a short period of time.
Gotta love the I-miev ... GOevn

Wondering how you're measuring this?

16 bars displayed is "100%"

Using the mut-clone i found that there is a capacity display value (meter) and a capacity control value (internally stored). This is what Malm discovered thru trial and error in all his experiences--the displayed and control values are not the same.

It's been the same since day 1 ... back n fourth to work same route sometimes rain .. I live in florida
the usual grocery shopping .. lowes .. etc .. charged on 110 when needed .. usually when 12 to 20 miles are left on meter.
66+ miles showing after charged .. I would check the odometer after driving reading pretty much dead on to the meter distance
I've never used 220v charge .. no need to .. charged while i slept .. Granted I've never did a meter test nor would I know how.
But I'm sure if there was any loss my range would be less than 60 miles by now on a full charge .. its not even close

Agreed

Every iMiEV driving around is charging to 100% (even if that 100% only has 3/4ths of the energy it had when new) so it's nothing worth crowing about - When you don't get 100%, you have a battery malfunction

I was just curious how our newbie was measuring his '100%' ;)

I believe our cars hide their battery loss from us. When mine was new, it would go another 6 or 8 miles at 50 mph *after* the RR showed '--'

I wouldn't attempt that now. I'm about 99% sure it would not do it if I tried, So 'still charges to 100%' doesn't really mean a thing . . . . at least not so far as an indication of how much battery capacity may have been lost is concerned

It would be interesting to see what Canion has to say about his car - There has been loss, guaranteed, and Canion would show it

The battery looks great - Very well balanced, however that page doesn't show you *anything* about it's capacity. As mentioned earlier, all fully functional batteries (no matter how much capacity they may have lost) will charge to '100%'

GOevn, in the above screenshot, the car was still charging [Edit: wrong! - the car had been discharging when the screen froze. See subsequent posts.] and the cells were being balanced. Agree with Don's comments. Do you have the latest version of CaniOn, as CaniOn now reads the battery capacity? BTW, I removed your other identical post to avoid duplication.

Phone reads caniOn141 ... what is the latest and where could I get it

The car was totally unplugged when I used caniOn .. maybe it still charges after being unplugged .. I have no idea

Looks like a frozen screen picture of stale data. The phone will retain the last screen before the BT connection was lost, and show this the next time the phone is turned ON.

you can see in the lower right corner that it is not connected, 0 frames per seconds.

The only degradation is the lower voltage at the top, it is showing 100% with the cells at 4.09 Volts. Cars with less miles will show cells charged up to 4.10 V.
