Restructuring EV charging infrastructure

[areleu]

Description of the issue

The current configuration for vehicle charging/tanking infrastructure is too coarse. From trying to annotate a charging station dataset we noticed some weak points.

• There is no discretization of the energy converting elements of a charging station. I would expect a charging station being able to have charging column as parts. The former would be the analogous to power plant and the latter to generator.
• Charging stations are usually differentitated as normal and fast colloquially. This may sound tricky but is easier to do when one considers the technical differences. Normal stations have AC configuration and Fast stations DC.
• It would be nice to add a part socket, plug or connector which itself can have different subclasses depending on the connection type and region.
  

Ideas of solution

Relabel oeo:00000031 electric vehicle charging station to electric vehicle charging column, keep same description.

Add new subclass of energy transformation unit using label of OEO:00000031(electric vehicle charging station) :

• electric vehicle charging station: An electric vehicle charging station is an energy converting unit composed of one or more electric vehicle charging columns and parking slots.

Add new subclass of artificial object:

• coupling component: A coupling component is an artificial object that joins two or more objects together.
  Examples: socket/plug, coupling, charging cable, usb plug...

Add subclasses of coupling component:

• power plug: A power plug is a coupling components that connects electric devices to a grid.
• AC power plug: An AC power plug is a power plug that conencts electric devices to a grid using Alternating Current.
• DC power plug: A DC power plug is a power plug that connects electric devices to a grid using Direct Current.
• electric vehichle power plug: An electric vehicle power plug is a power plug used to connect electric vehicles to a charging column.
• charging column has part some electric vehicle power plug

Add (a lot of) instances of power plug associated with electric vehicles:

EXAMPLE

• CHAdeMO 0.9 a electric vehicle power plug and a DC power plug
• CHAdeMo 0.9 is an electric vehicle power plug built based on the CHAdeMo 0.9 specificiation.

Workflow checklist

• I discussed the issue with someone else than me before working on a solution
• I already read the latest version of the workflow for this repository
• The goal of this ontology is clear to me

I am aware that

• every entry in the ontology should have a definition
• classes should arise from concepts rather than from words

Add (a lot of) instances of power plug associated with electric vehicles:

EXAMPLE

* `CHAdeMO 0.9` a `electric vehicle power plug` and a `DC power plug`

* `CHAdeMo 0.9` is an electric vehicle power plug built based on the CHAdeMo 0.9 specificiation.

I think that is way beyond the scope of the OEO but it might be a topic for the planned OTTO (Open Transport & Trade Ontology). Or are there any energy system models that explicitly model different plugs?

I tend to agree, what about the rest of the terms? I think the general differentiation of the plug types can be useful at the systems analysis level as they stress the grid differently.

Relabel oeo:00000031 electric vehicle charging station to electric vehicle charging column, keep same description.

• electric vehicle charging station: An electric vehicle charging station is an energy converting unit composed of one or more electric vehicle charging columns and parking slots.

I am fine with relabeling electric vehicle charging station to electric vehicle charging column and use the label for the new proposed class. But I suggest to keep electric vehicle charging station additionally as alternative label as the latter term seems to have more than one meaning.

• AC power plug: An AC power plug is a power plug that conencts electric devices to a grid using Alternating Current.
• DC power plug: A DC power plug is a power plug that connects electric devices to a grid using Direct Current.

Again, I am unsure whether we should include such details on plugs. More relevant seem the processes: DC charging and AC charging.
