My local Walmart installed charging stations. Granted Wal Mart has deep pockets but in the grand scheme of things someone at Walmart decided it was beneficial to attract EV's to their stores.
Places like Walmart or malls or factory outlets have to pick their equipment so the recharging speed is the same as a typical shopping trip length. So for an outlet centre if the typical shopping spree is a couple hours then maybe go with a 25 KW DCFC. Enough to dispense a reasonable amount but not too fast so the person would want to rush back to the car and disconnect to avoid idle charges. I think Electrify America has different speed chargers on some of their sites. I have seen as slow as 50 KW all the way to 350 kw for the Porsche crowd. Not sure what the charge price difference is.
Tesla does this with their 70 KW urban chargers in some locations. We have never used them but have seen them a couple times. Most Superchargers are 150 kw or 250 kw affairs.
