Games with the GOM (est 2.64 mi/kwh)

[Firn]

After seeing an estimated range of over 350 miles while charging to 100% I decided to see if the GOM ever settles down to a reasonable estimate. Readings were taken every 5% of battery consumed. This was mostly 55-60 mph county roads, two longer drives and then some running around so trip meter efficiency jumps around some.

Background - Efficiency over the last 5,000 miles shows 2.1 mi/kwh. Previous drive before charging to 100% was a 1hr 70mph run, estimated to be about 2-2.1 mi/kwh.

BLUF - At 100% GOM estimated around 2.64 mi/kwh, that was down to 2.4mi/kwh by 70% battery. Sadly this is inconclusive, my driving probably wasn't far off the 2.4 it eventually settled down to.

SOC (%)	GOM (mi)	Energy (kwh)	Est Eff (mi/kwh)	Voltage (v)	Trip Eff (mi/kwh)
100	347	131.5	2.64	391	-
95	321	128	2.51	388	unk
90	302	121	2.50	386	2.4
85	282	114	2.47	381	2.2
80	264	107	2.47	378	2.4
75	243	100	2.43	372	1.7
70	223	93	2.40	370	2.1

*Although 353 miles were observed immediately after it reached 100% that was down to 347mi by the time it sat for ~2 hours and I pulled it around from the garage.

2nd round.

SOC (%)	GOM (mi)	Energy (kwh)	Est Eff (mi/kwh)	Voltage (v)
75	236	99.7	2.36	372
70	210	93	2.25	370
65	195	-	-	-
60	175	79.5	2.20	360
55	157	72.5	2.16	357
50	152	65.5	2.32	353

Above 85% I have a hard time believing those efficiency numbers (and the GOM), but below that they seem to align fairly good with what would be normal for the drives I was doing.

In watching the GOM numbers it appeared that the GOM was tracking a reasonably short term average. When slowing from 60mph county roads to 35 in town the GOM went up slightly. This is also observed from 55% to 50% where there is a smaller decrease in range. This was due to slower speeds and turning off the AC.
