I work for Qualcomm at the "mothership" in San Diego, and as a result we
have several thousand people all in the same area. Being a high-tech
company, we have a LOT of EVs. Of course, we don't have a lot of
charging spots. The good thing is that we also have a wiki, a mailing
list, and a lot of well-informed people to help share the charging
spots. The only company edict we have is that we are allowed to charge
wherever there is a plug and a valid parking spot. The rest we have
come up with on our own, similar to what Mike has. Surprisingly, the
facilities people are very supportive - we have an email list to tell
them when a circuit breaker has tripped (too many EVs on a level 1 plug).
Bill and Dave still live on, I like to think. :)
Cheers, Peter

If I remember correctly, Mike's work is at the hp in Boise, ID. His
description of their inter-coworker cooperation and communication reminds me
of what hp was when I worked for them for 25 years. Its nice to know his
site still seems to operate using Bill and Dave's old-school methods,
whereas sites near hp Corporate in CA abandoned that long-ago when I worked
under CEO Carley's reign.
But large companies that don't have that 'on-the-same-page' attitude and
approach, have employees that are strangers and aloof to each other. Those
plugin drivers act like they are using public charging, where they do not
care about the other driver.
This becomes especially true the more EV charging there is at a site, and
when there are visitors using that EVSE. At Facebook in Menlo Park, CA

there is a fair amount of charging around the former Sun-Microsystems/Oracle
site buildings that an employee would likely not know the driver of the
plugin vehicle next to them. This is going to become more common as more and
more EVSE is installed at work and out at public locations.
Here are some examples of large quantity EVSE installations:

Houston's Tranquility Park Garage

Google says it will have 450 free charging stations on campus ...
There are several other multiple-EVSE sites, but I think that is enough to
make my point.

What I found interesting about GM's newswire release to the media, was their
late-to-the game effort to jump on the EV bandwagon. As if all their
million$ of dollar$ to fight against plugins should be forgotten, and now
they are the Good-Guys (?!?).
Particularly the sentence stressing that all EVs (which they still insist
the Volt plug-in-hybrid is) should be treated equally: do not unplug a pih
because you know it can run on fuel.
If a pih driver wants to use their pih in electric mode as much as possible,
I can see that point. But how does anyone know what a pih driver's habits
are. Clearly, a drained EV must get charging.
[Please lets not start a flame war on who should get what]
What I see is there is no established communication method between plugin
drivers to talk to each other and see if what each driver's needs are. That
is what I hoped GM would make happen. But all we got was lots of words that
whitewash GM to look good, and the public to feel-good about their belated
EV efforts.
Perhaps there needs to be a next-gen EVSE that is smart enough to know who
to ding the use-fee to, read the plugin's recharge-time desire, and adjust
that fee accordingly.
The EVSE owner may also want to sort out who 'needs a charge' vs who 'wants
a charge' using those different rate fees.
Perhaps the next-gen of EVs would have an EVSE interface screen on their
infotainment system that would let them select what charge to get (how
co$tly), and give data to the EVSE of what type of plugin it is, and how
badly it needs a charge:
-EVs wanting a higher/faster charge rate would pay more
-pih with on-board fuel would pay more
-EVs only wanting a low-n-slow and or an interruptible/V2G charge would pay
less
-etc.
Something has to be done to communicate who 'needs' what, else charging
situations can get nasty/abusive.
