A handful of battery options all ready exist that would support 15minute full-empty to full-charged capability.
However, to do this say a 5kWhr battery, you need a 20kW charger, and to do it on a 10kWhr battery you need a 40kW charger...
Carrying that on-board the motorcycle as a charger with AC input would be virtually impossible, as the charger would be at least 100lbs minimum, and occupy as much space as the current battery.
Which leaves you with DC-fast charging (how all EV chargers should be). With a level 3 DC fast charger (CHAdeMO), you're limited to 125amps charge current, so on a 100Ah battery you would still be spending ~45minutes to finish a charge from full empty.
So, I don't see EV's matching the 5-10minute fill-up time of a gas vehicle anytime in the immediate future, but as DC fast charge infrastructure grows, you're going to see the times to recharge EV's get much closer to the time to refuel a gasoline tank. One day it will be faster to charge EV's than to fuel a gasoline car. I expect we are at least >5 years off from that day happening though, and the big hold-up is more on the side of the chargers than the vehicles.
