Thanks for that information! So knowing the capacity loss you could massage the SoC% to better represent usable fuel, and should be the same as % of 281 right?

Depending upon how the car senses, calibrates, and develops the SOC,
Pack Capacity, and GID value estimates,...

Yes, they should estimate basically the same quantity, related to the fuel on board.
The SOC x Capacity might be close, or more (or less) accurate,
but unlikely to be exactly the same as the GID% value.

The 281 GID value is not arbitrary, even though it was originally
obtained through observations.

Notice that the 282 value (only rarely observed) is 94% of 300,
and 300 x 80 watt-hours (Nissan's stated value) = 24,000 (24 kWh).

Well this was fun.

My UK Leaf has been with us now for just over 2 years, and we've covered nearly 35,000 miles in it. It's currently covering 80 miles (ish) a day, including one rapid charge per day to 90 percent.

My friend Mark dropped by today with the homemade GID meter he and his partner have been working on. We plugged it into my Leaf and took a look.

Here's what we discovered: a GID of 278!

2 Years, a bunch of rapid charging (too many to count) and nearly 35,000 miles. And the UK climate has been kind to it. Only a 1% loss in capacity! :)

Proof once again that, particularly without a TMS, it is all about location!

Absolutely! I'll admit, we haven't had a hot summer now for about 3 years. 2011 and 2012 were both relatively cool, with average temperatures rarely above 70 degrees F. In fact, I'd be surprised if my Leaf has ever experienced temperatures above 80 degrees -- except in the paint booth before the battery pack was even fitted!

Rolled into 15K miles/13 months yesterday and my 100% Gids this morning was 255. That is about 10% degradation. And I am betting around 5% of that happened even before I bought the car from the dealers lot which I believe it sat for nearly 6 months (during winter time though) mostly at 100% charge.

I have to admit that I babied the car for two months during peak summer here in Dallas, by charging it outside during night time, and not driving it around during a few weeks of 100F+ days. But I am glad I did that, because it is helping me on my new 70 miles round trip commute, which I am sure I could not be doing it, if I had not been taking extra care during those peak summer months.

Haha :) I haven't watched her for ages. Is she a taste of home there, Mr. W ? :)

Hey Dave, that's great news. I guess that's case in point that WA is like the UK in terms of weather eh?
