The 2013 dash value is State of Fullness, not State of Charge, so they
should NEVER match after a full charge, when SOF should be about 100%
while SOC should be around 95%.
NEITHER of these indicate how much fuel you have on board, since the size of
the fuel tank can vary. A 100% full reading on the dash, with a battery pack
that is down to 80% capacity, results in only 80% GIDs percentage (fuel).
thus, the dash SOF and the SOC numbers are basically useless
for estimating range over the long term.
The dash number and gauge is tank FULLNESS, not a "fuel" gauge.
However, even GIDs are just an estimate,especially at the low end.
When the battery is hot, the car's BMS can decide to use less of the
battery capacity, in an attempt to reduce or slow the detrimental
aging of the battery at higher temperatures, especially when aggravated
by near-full SOC.
So, in the hot temperatures, the battery can "appear"
as if it has lost capacity... because the BMS has decided it is prudent
to use less of the battery capacity for the hot season. (I believe)
