So I find myself rather embarrassingly ill-equipped to advise my employer
about installing EVSE stations. I can get to work and back OK if I drive
conscientiously, but not during winter. An EVSE at work would be very
handy. There are some receptive ears at work and there is a substantial
parking lot expansion coming up, so I convinced them to at least plan for
getting some power out there. And I, being the closest thing they have to
an expert on EVSE, would get back to them with my recommendations.
Am I beating Robert to the punch here?
The really big question is whether your employer will foot the electric
costs. If so, a multitude of 120vac connections are likely to be of FAR
more use than a few commercial EVSEs. I suggest working up installation
and operating costs of each. With a multitude of 120vac connections you
remove all contention for the charge positions. And the added range
will likely suit most everyone; charging at ~1kw will add 3-4 mph. 30+
miles for a work shift.
The SOLE advantage of a commercial EVSE is the ability to shift electric
costs to the user. Tesla owners FAR prefer RV outlets which can supply
40 amps vs the typical 30 amps (or less) from a commercial EVSE. So, if
your employer is willing to pay for the electricity, I would recommend
one or two RV panels and MANY 120vac outlets.
