A good question, and I'm looking at it from the point of view of a lot of new EV owners who are "normal" and not mad keen enthusiast adaptor collectors like many of us! For that reason I'm not including "power socket" sites (10A, 15A, 3-phase) nor Tesla specific infrastructure in this post.
I think the biggest step is that cars need to be sold with a Type 2 cable included, same as in Europe. That'd fix it for the majority of sites.
There aren't any government mandated standards in Australia, but the FCAI has agreed that:
- DC charging stations should have both CCS2+Chademo plugs
- AC charging stations should have Type 2 sockets (without cable)
- new vehicles should have CCS2 inlet (capable of accepting CCS2 + Type 2) or secondary preference, Chademo + Type 2 inlets.
All CCS1 charging stations and vehicles should be phased out (plenty of discussion re: adaptors occurring elsewhere in the forum).
J1772 cabled stations will probably hang around for some time, we shouldn't be installing any more of them. They'll probably get replaced gradually, there is the risk of new EV owners rocking up to them and finding they can't use them. Not too bad at the moment with the large number of Leafs, also with many EV owners expecting to need a variety of adaptors. But there are more and more first time owners who won't be installing a bunch of apps or looking up plug types, who just want things to work. Options I can think of:
- Provide a J1772-Type2 adaptor with the car
- Have the vehicle navigation system automatically filter out locations that aren't compatible
- Blanket replacing all J1772 charging units with Type 2 sockets
- Ensure there is another nearby Type 2 location that can be used
(All of this only applies to public stations. For private use, of course people can install whatever suits!)
