Surely, 125% should be used for maximum demand for individual load or groups of loads per NEC.NEC states that if a load is on three hours,it can be treated as continuous load.Loads on for 3 hours only and loads on for 24 hours are both continuous.But a mixture of both will not have the same maximum demand as that had by loads for 24 hours i.e.,their demand factors are different .
The OP is requesting for a thumb rule for demand factors also.So why can not the link suggested in post#2 be used for that purpose?
The link applies only to Oregon, if that measure has passed, though a good idea, until it is adopted by the NEC or the locality or state in which the OP presides, it cannot be used for the OP's purpose unless the chargers are in Oregon. States can adopt or modify stonger or weaker code requirements at their own peril. In the states, each state can have different laws that affect you only while in that state, I believe it's in New Jersey where it is illegal to pump your own gas, but the rest of the country you can.
