The sales pitch, as delivered to one of the potential buyers, the sit-down casual restaurant owner:
A 20kW Chademo charger would be great for a restaurant owner, you know the driver will go in and buy something during that hour charge time...
Actually, you don't.
I recently spoke to the owner of a restaurant who installed a "Tesla" roadster charger.
He got the Charger installed for "free", in return for the "free" kWh, he provides Tesla Drivers.
Apparently, even $100k+ BEV drivers can be cheapskates, at least occasionally, and will just sit in the car, and not even come in to buy a cup of coffee.
IMO, while the fee-per-kWh will probably be as low as possible, to attract BEV drivers to a particular location (not unlike the loss-leader sales tactics Costco and mini-marts use for their gas pumps) a separate charge fee, per kWh, is essential to establishing a functional Charging network, whatever the rate of charge is.
The point is, while I see a case where 10-20 kW charge rate will be "fast enough" in some cases (such as at restaurants, or in lightly-travelled regions locations where sales volume cannot support more expensive 50 kW installations).
I can see no viable economic model for L2 public charging (unless
both the L2's and the BEV fleets are designed for faster than 3.3, or even 6.6 kW, charge rates) in the majority of locations they have been placed in so far, in "free" parking lots, providing "free" charging, in front of business's with (typically) very short parking times.
