I am designing a facility that is requiring 26 Level 2 Electric Vehicle Charging Systems (EVCS). Art. 625 states that EVCS shall be considered to be continuous loads.
The issue I'm having is that I can not find a reference in the 2011 NEC that allows or disallows the use of a demand factor. Since not all of the charging stations will probably not be used at the same time, nor for the entire day. Once a vehicle is charged, it stops charging, or goes into a maintenance charging state.
I was wondering if there is a code or rule of thumb to use for the demand code for the EVCS.
Thanks.
