Quick question regarding the EPA testing of the Plus and the 3 SR+. When looking at the comparative findings, I am a bit confused between the listed "Energy Capacity" and the kilowatts charged.
The Leaf Plus is shown with an Energy Capacity of 176 (no Units on the line)
The Tesla 3 SR+ is shown with an Energy Capacity of 230
Leaf Plus Battery Specific Energy: 140.9
SR+ Battery Specific Energy: 150
(Page 3 of each pdf)
On the face value, this would seem to imply that the SR+ has a larger battery.
Lower in the report, on the recharge, it showed:
Leaf Plus recharge of: 68.3 KW
SR+ recharge of: 62 KW
Both I assume are wall figures, so subtracting 10% would give you the ~61KW usable in the Leaf and ~55KW usable in the Tesla (as is widely reported).
So the question is why the higher energy capacity showing higher on the Tesla. Is that because it is electronically limiting the capacity available?

SR+ Report:

While I love my Leaf+, It is interesting to see that the Dyno tests for the SR+ are higher then Leaf. Test weight is significantly higher in the Leaf than the SR+ which likely accounts for much of that difference, given these tests are sans drag. (Test weight of 4250 for the Leaf vs. 3875 for the Tesla). The difference is about 10% for both weight and dyno distance.
Does any one have comment/understanding in the different battery measures as to why they differ?
