Glad you posted the output of the L2 charging station John. It is my belief, that outside of emergency/last resort charging for longer range EV’s, L2 charging is really more about providing range for lower range EVs (with range < 125 miles or so), PHEVs, and those who don’t have access to L2 charging at home (or even L1). If one’s EV/PHEV can charge at say 9-12 kW (pretty much the upper end these days) and the L2 charger can also supply that, then a 30 minute L2 stop could add around 5-6 kWh of charge (which might translate to 20-25 miles of range, best case). I would argue, that at least under those ideal circumstances, that may be useful range, depending. Your trip out to the chargers was useful in that it provides one example of “real world” data, useful for comparing to the back of the nanking numbers one could also do. I would be interested to know (and realize it would take a fair amount of work to find out) how many L2 chargers in the Boston area (or the Seattle area where I live) offer >8 kW supply, and how many EV/PHEVs actually registered can charge at a rate >8 kW. I know Teslas can (at least for the most part), and I know other brands can as well... but it seems like many PHEVs and lower range EVs are likely <8 kW capable on L2.
As a note of comparison, when I tend to use public L2 charging (for example when I go to wineries that offer them), I tend to get about an hour worth of charge. So people using them for longer stops, rather than bio breaks, may actually get 50+ miles of charge. I think many people would use them as such while shopping, dinning, going to a movie, etc. That is probably a more relevant use case study, IMO. Good work!
