[[]] Question from Duane Jonlin:
If we were to start providing for future large-scale EV charging infrastructure in new and renovated buildings, what’s a reasonable electric load per 100 spaces to assume? It would be different for apartment buildings, office buildings, retail & entertainment, hospitals, schools…
Would we assume that the great majority of drivers would charge up overnight at home, and not really need charging at the office or clinic or movie theater? In that case, we’d just assume a small proportion of cars (5% or less) would be charging at commercial establishments at any one time, but that a large proportion (50% or more) would need charging sometime between 7:00 PM and 7:00 AM at an apartment building.
In the garages, it doesn’t seem reasonable to provide for outlets at every single parking space. Maybe there’d be a few short-term parking spots for those cars that needed active charging (in case someone needed to drive to an appointment that morning), and a larger number of parking spots for people who only wanted to have their cars charged sometime before they left the office at 5:00…
But I digress. I’m really trying to figure out what exactly I will be asking City Light to provide for new buildings, and I don’t want to operate under assumptions that wouldn’t bear up under questioning at a City Council meeting! For, say, a 200-car office building garage, how much charging power will we need 10 years from now?
From Don Chandler (VEVA in BC - helped write the EV codes for Vancouver 5 years ago):

Don't get Distracted by "Issues" that only effect 3% of Charging! Almost all of the issues and problems we frequently hear about charging infrastructure apply only to L2 charging. All of these issued vanish with L1 (120v) charging. Few if any issues are involved with just plugging in an EV like plugging in a coffee pot. And many of the outlets already exist!
IEEE National Committee on Transportation and Aerospace
FOCUS ON THE 120v OUTLETS FIRST! Too many bureaucrats and initiatives are too focused on the expensive Level-2 and L3 EV quick charging stations and promoting public EV charging infrastructure as a way to combat Range Anxiety. This focus on public charging which is only the tip of the Charging Pyramid as shown above is doing more to underimine the adoption of EV's than to help them. Range anxiety is a self-fulfilling prophecy if we keep focusing on the need for fast routine public charging. Also the emphasis on charging speed is completely misplaced. At every level of the charging pyramid, except the top, charging is not a separate go-to process but is just an added 5 seconds on the parking process. The only place where EV charging speed is paramount is along the interstates, where the only reason for being there is to charge and charge fast to get from point-A to point B. Every other level of the charging pyramid is simply charging conveniently while we are parked. And when you are parked for 4 hours or more, 120v standard outlet charging is just fine. Park at-work, Plug-in at work and double your range!
L2 Chargers at work are ineffective: The expensive high-cost Level-2 quick chargers at work locations and campuses makes little sense for the employee or employer. Employers are not going to want their people doing musical-chairs in the parking lot every hour and rotating one EV off the charging station, and then rotating another one in its place? No. We need 120v convenience outlets on every lamp post and in many cases they already exist. We simply need the means for EV owners to pre-pay for the electricity so that then they get permission to plug in.
