In fact, a good hydrogen EV will take about 25-30 minutes to refill at -10C ambient.
Thas a good point, i looked into it, and it seems to be because having the water in the fuel cell ice up causes major problems...

..however, the above article seems to suggest that they think they might be able to solve this , "might".
That is a 17 year old article Toyota's Mirai works down to -30 deg. C https://newsroom.toyota.eu/the-new-toyota-mirai/
Works != is a good performer.
Hydrogen vehicles still struggle to fuel when very cold - it's an unsolved problem with the technology.
Meanwhile a Tesla EV with a preheated battery can supercharge just as fast at -10C ambient as it can at 40C ambient.
Opportunity charging at a supermarket or other public place also makes you a target for <insert something bad here>. I can see places of employment because many are behind fences but I'm certainly not going to charge right next to an ATM machine.
Can't see an AC charge while getting cash out being worthwhile (what, 250Wh, for 5 minutes at most?) But at a supermarket you might be there for 45 minutes - 1 hour every week (depends how efficient you are I suppose.) And I don't see why charging would make you any more of a risk, especially given it's more and more common. I guess a moron could try cutting the live electrical cable. Let's see how that goes for them.
Were I still working, I would have been the guy building out multiple charging stations for our employees. As we were essentially an engineering division of some 10,000 employees (far less in later years), how many stations would I need? 10% of current headcount? We had enough incoming power (115kV 28MVA easily) but I would have had to dig up a lot of pavement to get the 12kV over to a dedicated substation (or several) to provide 240V for the chargers. It would have been a monster project but the company would have just considered it a cost of doing business. Charging would have been free. I don't know what it might cost but I know I would take a flogging every day for a) it isn't done yet and b) it costs too much. Such is the life of a project manager.
Workplace charging is a good example of somewhere where 2-3kW chargers are perfectly adequate. Cars are typically parked up for between 8-10 hours per day, so even 2kW would get you 16kWh and for a five-day week, that's nigh on 80kWh - few people would use that much for their commute.
It's my understanding that many old car parks in the USA had 'block heater' supplies in the colder states, at least at one point. I think EVSE supplies in workplaces could be like this - 115V 15/20A single phase (and in Europe, 230V 10A.) Unfortunately, regulations mean that EVSEs are a lot more expensive than just supplying power, what are you gonna do... but, despite this, they're still much cheaper than the actual cost of installing the parking space in the first place. (An average 'space' in a tarmacked parking lot is ca. $8,000 -- so a $400 EVSE isn't really going to blow the budget.)
