It depends on many factors such as battery size, OBC wattage, how far people are commuting from, pricing (if any), penalties for occupying a spot beyond a certain amount of time, whether folks charge at home at all before coming to work and placements of stations vs. parking spots (i.e how shareable as an EVSE or J1772 handle vs. parking spots: only reachable from 1 spot or by 4 to 6 spots?)
From my rough experience (but I'm not part of facilities at my work nor our Chargepoint admin so I don't have direct access to stats), I'd say each handle for free charging at my work w/no penalties for overstaying can probably handle 3-5 vehicles/day at max, unless folks intentionally limit how much/how long they charge for and unless a good notification system is set up for when they're done, have vacated a spot, etc. And, this is in the absence of any sort of EV valet or someone that goes around unplugging finished cars and plugging in waiting cars. This also assumes typical "business hours" and not a place w/multiple shifts. If it had multiple shifts and the place ran 16 to 24 hours/day, it could support more.
I don't recall what Chargepotnt's recommendations are but https://www.chargepoint.com/about/news/ ... -charging/
1. Scale Up
Workplaces have recognized they need one charging spot for every two EVs. This allows people to plug in when they get to work and then move their charged car at lunch so others can plug in during the afternoon...
