I don't understand why everyone is dancing around the question. This is simple math after we get past a couple of assumptions. here are my assumptions:
Usable pack capacity = 24 kWh
Low battery condition is raised at 15% capacity
Note that all Nissan charge time estimates (L1, L2, L3) are based not on a completely discharged battery, but on charging from the point where the low battery charge warning light comes on. See page CH-6 in the owner's manual.
With my assumptions, charge to 60% really means (.6 - .15)*24 kWh = 10.8 kWh. Even if charging were 100% efficient (which it can't be), to get 10.8 kWh into the battery in 5 minutes (1/12 hour) you need to apply 10.8*12 = 129.6 kW.
Given a 50 kW maximum charging rate, there are no reasonable assumptions which could get close to 60% in five minutes.
