Interesting.At the fontana event I asked a ford rep about battery sizes.. He told me that:
Standard range battery will be between 90-100kWh
Extended range battery will be around 130kWh
These are usable figures and make sense to me if the the lightning can achieve 2.3m/kwh (similar to the R1T)
Assuming 130kWh usable, then 65% would be 84.5kWh and in order to charge from 15% to 80% in 41 minutes, it would need to average... 124 kW !
So, in that sense this rate and the battery size make sense.
That said, 130kWh doesn't line up with the A/C charging info Ford provided. Ford says the ER battery will add 13 miles of range in 1 hour of 32A/240V charging. So, before losses, that's 7.68kWh in an hour. If it gets 2.3 mi/kWh (300 miles/130kWh), then 7.68kWh would give 17.6 miles. For 13 miles to be correct, it would have to lose 26.5% between the wall and the battery. That's really high losses for Level 2, especially for a 1-hour charge vs. charging all the way to full or charging at a low rate like 120V.
Maybe those numbers are conservative, though? Who knows?
