So we have a few more specs.
0-60 under 7 seconds
Up to 25 miles of range per hour, 9 hours to charge using a 32 amp charger (7.7 kW), meaning 225 miles of range
That means likely 60 kWh of battery (7 kW making it to the battery, 9 hours including some taper).
Of course, 225 miles in that shape likely is "ideal range" and not EPA range. They only need to hit 200 in UDDS range.
Originally in the Bolt's website, it was 80% in 45 minutes, which is about on par with Tesla's 80% in 40 minutes. With the NMC chemistry, I expected that they would be able to handle a higher charging c-rate, maybe going for 80% in 25-30 minutes, even if few CCS chargers can deliver that kind of power. At 80% of a 60 kWh battery in 1 hour, that's 48 kW making it to the battery. That's kinda of terrible.
