SubjectEVSE 15-day Comments: DCFC verses HP DCFC
Comment
There should be a Definition for High Powered (HP) Liquid Cooled
DCFC chargers compared to the standard DCFC.  The standard DCFC
station will not charge a High Powered Liquid cooled vehicle, these
vehicles can only be charged with the HP DCFC due to the higher
voltage in the vehicle.  There should be a distinction between the
two; otherwise drivers will not know which type of DCFC charger is
the station until they try to activate a charging session and it
will not work.  
This will be confusing and could create poor EV experiences and
potentially excessive down time.  With the most recent and more
advanced technology that includes the higher Power Ratings in these
HP charging vehicles which is currently available in luxury cars,
some MHD Trucks and Buses there needs to more accurate information
among these two very different DCFC voltages.  This will be the
future and we are already seeing this technology in the Electrify
America HP Charging stations, luxury vehicles (Porsche), and the
Green Power Buses.
