Ok, I don't know why this is bothering me, but I propose that we adjust our formula for Gids to read 100% at 281 Gid and 0% at 7 Gid.
This will more accurately reflect the 21kWh usable power, since the bottom about 300-400 watt hours are not usable, but included in our percentages.
(281 GIDs / 13.38) = 21kWh * 4 miles per kWh = 84 miles. But, as we know, any simple formula like that leaves miles remaining while the car in in turtle. Not wise.
Therefore, I want 7 Gid to be "zero", which also reflects a more accurate 50% useable energy level (a key metric to know when it's time to go home), hence the Gid2 formula:
(GID -7) / (281 - 7) = GID2
So that 281 GID = (1 * 21) = 21 * X miles per kWh = Y range in miles
And that 144 GID = (0.5 * 21) = 10.5 * X miles per kWh = Z range in miles
And so that 7 GID = (0 * 21) = 0 * X miles per kWh = 0 range in miles
The new 2013 will show 100% regardless of capacity, when fully charged, and show the following:
SOC% - "kWh usable" --Gid----Gid%---Gid2%---2013 dash % (2013 dash % data based on SOC%, not Gids)
95.x% -21.0--Full----281---100%---100%----100% (non-degraded at 70F; 21kWh usable)
------10.5--Half----144--51.2%----50%----50% (non-degraded at 70F; 10.5kWh usable)
95.x%-10.5--Full***--144--51.2%----50%----100% (***used 50% degraded at 70F; 10.5kWh usable)
------ 3.2---LBW----49---17.4%---15.3%----17%
------ 1.3---VLB----24----8.6%-----6.2%----8%
2.x%-- 0.0---Turtle --7-----2.5%-----0%-----(---)
NOTE: LBW and VLB are indexed to Gids, therefore those values won't match the SOC derived data of the 2013 dash % with a degraded battery.
Turtle is not indexed to Gids, therefore under a high load, like freeway speed, expect turtle at 7 or 8 Gids, and at extremely low power, as low as 4 Gids to Turtle.
