Re: Hydrogen? Seriously?
"An average EV charging site might have 2 chargers, or 4 if you're very lucky. Not all of the chargers available work with all EVs, some EV charging accounts only work with specific chargers."
Most EVs use CSS for DC fast charging other than the Leaf (ChaDeMo) or many Tesla's with their proprietary plug. Charge stations will have both CSS and ChaDeMo or will be a Tesla station. Level 1 and 2 charge points work with all cars (Teslas with an adapter).
The way you pay hasn't been rationalized yet other than with Tesla for which you must have an account with Tesla and the car can't have been abandoned by them (salvage title/Rebuilt). Even if you don't have an account, most non-Tesla stations can be accessed by signing up right then and there or using a offered payment method. I'd really like to see chargers at petrol stations have the option of being paid for inside with cash. I've had my debit card cancelled before due to fraud at a time when I was out of town. It would really suck to find this out if I needed to charge up.
If you can't charge your EV at home/work, they may not be viable for you yet. If you do have off street parking at home the chances are that you are falling for the myth that you need to have charge stations everywhere to be "fuel secure". Even in winter a modern EV with 250-300 miles of range is going to go 180miles on charge. That's 3 hours of driving at 60mph. How often does that happen? Again, if you have charging at home, you can set the car to pre-condition the battery while plugged in and EVs will also optimize battery temperature for fast charging if you tell them you will be stopping at a fast charger so you will get the best possible charging rate on those long trips.
If you accept that every 13amp outlet close enough to the car to plug in is a charging point, yes, there are more charge points than petrol pumps in the UK. Look for photos online of people that have strung a cable out of a window to plug in an EV. Not all that safe, but will do in a pinch.
