Poll: Guess 70 mph Steady State Range of Model 3 Vs Bolt

[Model 3]

No, I wouldn't say that the pack is that big. More likely the 58kWh usable with 60 (or just slightly more) kWh nominal estimate is close, but maybe it's 60 kWh usable and 62 kWh nominal.

Rumours say 66kWh nominal with 60(+?)kWh usable.

It will be interesting to see if Chevy starts a trend about reporting usable kWh of battery instead of gross size.

They already pee'd in the cornflakes of the other automakers by using the tighter SAE HP spec before it was widely adopted.

Oh. So the EVSE said it used 68 kWh to charge the battery, but that doesn't include charging efficiency (or whatever the correct term is here)? That makes sense.

He may only be referring to efficiency from battery to motors and not the use of a rectifier to charge the batteries

Is it known whether L2 or L1 charging ?
The efficiencies differ, but for a ball-park estimate I use 15% charging losses.

If 68 kWh consumed at the wall, then 68*0.85 = 57.8 kWh went into the battery.

I'm guessing it was L2. Sounded like they started charging around 11pm and then they checked it "the next morning" and it was full. With a supposed 9 hour charging time on L2, seems unlikely it was L1.
