Hi All,

Last week at Haystack Connect the EV charging working group presented several working drafts and background and motivation behind the working group. We invite you to review the recording of the presentation and let us know if you have any questions.

Today we would also like to offer the community an opportunity to provide comments on the draft model for evse-assembly-equip described in this link and below.

  EVSE is the acronym for Electric Vehicle Supply
  Equipment.  An EVSE facilitates the transfer of 
  electricity between the electric grid and electric 
  vehicles via one or more EVSE ports.  EVSE is also
  referred to as a charging station, charge point, or EV 
  charger.  In some regions of the world, it is
  understood that there are three types of EVSE:
  Level 1 AC, Level 2 AC, and Level 3 DC.

  Equipment that facilitates the transfer of electricity 
  between the electric grid and electric vehicles.  See
  `docHaystack::EVSE` chapter.

def: ^evse-assembly
is: ^evse-equip
doc:
  An EVSE assembly is a manufacturer produced, safety 
  certified combination of hardware that facilitates the 
  recharging of electric vehicles via one or more EVSE ports.  
  It has manufacturer provided technical specifications and
  instructions on how to be installed and operated.  Also, it
  is comprised of one or more equipment enclosures and power
  fed from one or more branch circuits.

def: ^evse-port
is: [^evse-equip, ^elec-meter]
doc:
  An EVSE port provides power to facilitate recharging a 
  single electric vehicle at a time.  More than 
  one EVSE cable or pantograph may be connected to a single 
  EVSE port, but only one may be energized at 
  a time.

def: ^evse-cable
is: ^evse-equip
doc:
  An EVSE cable provides the electrical connection between an
  EVSE port and the inlet of an electric vehicle according to
  a standard such as SAE J1772, SAE J3068, CCS1, CCS2, NACS, 
  CHAdeMO, GB/T, or MCS.

def: ^evse-panto

doc:
  An EVSE pantograph provides the electrical connection 
  between an EVSE port and the inlet of an 
  electric vehicle according to a standard such as (to be 
  later defined).

Please let us know what you think! We value any feedback provided.

Hi,

As a follow up to my recent post --

The equip ontology for Electric Vehicle Supply Equipment (EVSE) is now published into the docs. See the new docHaystack::EVSE chapter for the current proposed model. We continue to welcome any feedback from the community on this proposal.

Also, to provide more context to how we propose to model EVSE here is a link from InsideEVs that describes some of the North America EV charging standards. The EV charging standards in other regions in the world are similar but require important distinction. Our working group intends to define a model that supports all types of EVSE.

Thanks,

Rick
