Sorry. I'm new at this. I've tried searching, but no joy.
What is a Gid?
Thanks in advance.
What is a Gid?
Thanks in advance.
Would be nice, except that the gids were discovered WAY before the 2013 Leafs became available. '11 and '12 Leafs have no % SoC display. They've only got the GOM, the 12 "fuel bars" and the estimated time to charge.ObiQuiet said:It would be good if the wiki explained how linear or non-linear the correlation between Gids values and the SOC% reported by the dashboard are to each other.
I've been using Leaf Spy on my 2013 for about five months, and the dashboard SOC is always the same as Leaf Spy's % GIDs, except when the dashboard says 99% or 100%. The SOC % in Leaf Spy is usually different by 1% to 4%. So I'd say the dashboard SOC is quite good, except at low SOC when it disappears.cwerdna said:Would be nice, except that the gids were discovered WAY before the 2013 Leafs became available.

TomT said:The problem with SOC is that it does not represent a constant amount of energy... As the battery degrades, each SOC percentage will represent a smaller and smaller amount of energy... With Gids, the amount of energy represented remains basically constant. Think of it this way: SOC represents the amount of energy in the tank, regardless of the size and capacity of the tank. GIDs represents the amount of energy in the tank regardless of the size and capacity of the tank...

The question was whether the dashboard SOC is linear with respect to GIDs. The answer is, in my experience, yes.TomT said:The problem with SOC is that it does not represent a constant amount of energy...

GID: Unit of Charge reported by Gary Giddings' SOC meter. 1 Gid = 80Wh nominally, 100% Charge = 281 Gids on a new battery in a cold climate. "HV Battery Level" in Nissan vernacular. CAN bus message 0x05BC and displayed in Wh.

It SHOULD say:
SOC represents the percentage of energy in the battery, from full to empty, regardless of the absolute capacity of the battery.
GIDs represents the absolute amount of energy in the battery and that amount will decrease as the battery degrades and with changes in temperature.
