I've used a half dozen or so of the medium speed chargers, and occasionally mull what it would take to install one at home.
Specifics of the particular session: 39 minutes, 12.40 kWh added at Harley Davidson dealer Baymeadows, Jax FL. Gotta love ChargePoint statistic records!
The one's I've used are KeyWatts at 2 BMW locations, the HD one cited earlier, and a Chevy Dealer's Bosch / Delta unit in Gainesville.
I'm not sure where these fit in to the future of public charging infrastructure - The vast majority of EV charging is now at home...most of the rest being rapid charging while on long road trips where speed is paramount.
Another segment is destination charging - L2s in hotels and at workplaces where hours of parking time are available.
If a charger owner / operator threatens to call the fuzz, fine...whatever. Leave and warn others on Plugshare...also leave a 1 star review on Google and wherever else one writes online reviews
Ga2500ev - interesting point - some thoughts on medium L3s:
1) May well form an optimal middle ground for EV adoption by folks unable to have L2 at home - renters, apartment dwellers, homes with inadequate electric service etc
2) These add useful amounts of charge during longer errand - type stops - grocery shopping, public libraries, big box stores. Obtaining 30-40 miles of range during a 30 minute shopping stop provides right at what the average daily driver needs.
Getting, say, 3 kWh / 12 miles of range from an L2 station during a 30 minute errand stop would generally be not worth the hassle unless one's car is very very low on charge.
3) Installation cost much less than faster stations - KeyWatt and Bosch have variants that run on single phase 208 / 240V circuit. Installed cost $20-30k maybe?
4) Less impact on host electric bills, though impact on demand billing must always considered.
5) Free isn't sustainable - should be supported by per-kWh (where allowed) or similar per minute rates. Might be attractive / conducive to EV adoption at cost per kWh no more than twice the at-home rate...much higher than that might ward off the budget-conscious. 6 to 10 cents per minute might be in range.
There are probably synergies available attractive to retailers - knowing one's car needs a bit more charge could encourage shoppers to linger - ALWAYS a good thing for retailers. Imagine also affinity card synergies - swipe to start charging at a lower cost using store credit card or membership card - get charging credits in exchange for shopping. Local retailers already have shop-for-cheaper gas deals...in the case of EVs, the retailer gets to "sell the fuel" without tanks and gas pumps and all that entails.
6) Battery degradation - many of us worry, to varying degrees, about accelerated battery degradation stemming from very fast charging. Medium speed L3s would seem to balance that concern against getting a useful amount of charge while shopping.
7) Medium L3s could represent a niche not now well served - Electrify America and EVGo are plowing millions into very expensive, complex high speed chargers. That's great - we need them for road trips. However, the cost and complexity of siting them probably means we won't ever have anywhere near many of them as we now have gas stations.
8) I'm less sure how well medium speed L3s would work for apartment complexes - their managers around here more often than not let dead couches and mattresses pile up for months at a time, never mind splashing out $20-30k to put in a charger...that said, the bigger problem would seem to be getting people to move cars after an hour or so after arrival.
L2s would probably make more sense for apartments - overnight charging in the parking spots nearest where electricity enters each building might be easiest to install.
Medium L3s might eventually make sense in low-end apartment complexes whose units lack washer dryer hookups - tenants spend 30-60 minutes at the central laundry building. If multiple electric dryers are installed, there's likely a fairly heavy duty electric service in place...For this to be worthwhile, EVs will have to have trickled down to the income demographic that uses central laundry buildings / laundromats...that could be a ways off.
