GT = 22 modules = 924v
T & P = 18 modules = 756v

the Air charges fastest because it it the highest voltage. Right?
What is the charge rate for Touring and Pure?

So if this has already been answered.
 
This is an interesting question without a simple answer. Charge rate at first is limited by max current that will not harm the battery cell, then by self heating, then by how quickly heat can be removed from the battery, and then by not overcharging the battery cells when they are near full charge. Tom Moloughney showed this in the charging curve for the dream edition, see below.

If we assume that thermal managment is limited by heat transfer within the battery pack rather than capacity of the cooling system, then the Touring and Pure will charge at the same current as the GT and Dream. Hence, time to charge from 20% to 70% will be the same. However, with the different voltage, the kWhr gained in that time will be around 20% higher for the GT and Dream than for the Touring and Pure. The real bottom line is how many miles can be added in a given amount of time. Unless the Touring and Pure are 20% more efficient than the GT and Dream, they will not charge as fast. Until we see the efficiency numbers and know for sure what is limiting the thermal management of the battery pack, we will not know how the charging rate compares.
