[ausev] 110 or 220??

[Aaron Choate]

To add to this, the requirements to allow 220 charging from upcoming public
charging stations when/if they appear are likely to require vehicle
communication and specialized (J1772) plugs to activate the charging
sequence.  While there is no guarantee that a 120 outlet will be provided at
all down the road, they are what are most likely to be appearing in the
short term in most initial tests.  Whether that 120 outlet is like the ones
in your home is another question.  Though, as I recall, these plugs are
allowed to be included without special provisions.  In fact, the Electric
Vehicle charging spots at the SEDL building at the Mueller redevelopment are
just that... standard 120 outlets in outdoor enclosures with a sign. (asking
that you be visiting them if you are using the spots)

Cheers,
