Cohousing-L Mailing List: Re: more on EV charging stations from River Song

[Chuck Harrison (cfharr]

@Philip Semanchuk It sounds like you have a handle on computing the total
kWh required per month but your conclusion that only a few stations are
required is an unusual one. Our own community has assigned parking spaces
and has come to a different conclusion: that a station should be located at
each EV owner's parking stall. This avoids the middle-of-the-night shuffle
that Fred refers to.

The size of the electrical service required to charge a few dozen vehicles
is actually pretty modest (as your spreadsheet probably tells you). The
most impressive work I have seen on estimating service requirements is done
by AES Engineering in Vancouver BC. A good contact there is Don
Chandler, Don.Chandler [at] AESengr.com . Don can point you to some general
documents, or some communities might want to engage AES for a site-specific
consultation.
