You are right, my mistake. 190 mile range is more 75 mph.GetOffYourGas wrote: I'm not sure where you are getting this.
As an aside, as a ballpark estimate for most cars, I use the EPA highway figure MPGe (corrected for charging losses) as a surrogate for travel at 65 mph. So in the case of the Bolt with a 110 MPGe and 60 kWh max usable battery the range works out to
60000/(33700/(110*1.12)) = 219 miles*. This rule of thumb underestimates the range in cars like the Tesla with unusually low CdA values because the actual EPA testing occurs at a much lower speed and then a 30% discount on the range is applied.
These discussions should keep in mind that we normally assume EPA testing like conditions of travel, meaning 50 - 80F ambient, not wet, no snow, and no headwind.
60,000 - Wh battery capacity
33,700 - Wh in one gallon
110 - Highway MPGe
1.12 - 12% charging losses
