so 30 million cars share about 8000 petrol stations. However this rates the village garage with just 2 pumps and a sideline in red where they have to find the key to turn it on for you, with the 6 lane 12 pump monstrosity at the side of the motorway.

however compared to electric the time to fuel up, or if you prefer the megawatt rate of a hose delivering E10 is soberingly high.

We have a two 2 pump station BUT it can fuel 4 cars at a time (one each side) . Is your location like that?

I estimate it takes us a total of 5 -10 minutes to fuel our car with 7 US gallons of gas . That includes waiting for the clerk to activate the pump.

Remember the US gallon in 80% of your old UK gallon. I usually refuel the car when hitting the 1/4 full tank reading.

The other factor is that for any type of car, it is usually parked (at home or at work) . I have seen a published fudge factor, that it is parked at least 80% of the day.

EV's on the other hand have a number of charging rates with the trend to higher and higher rates depending on battery constructions and the cars software.

As a comparison, the statistics provided by Zap Map suggests that there are 1,145,000  full-EV's in the UK sharing 64,775 charging points across 33,829 locations (so an average of 2 chargers per location?).

So where as the data suggests 3750 petrol/diesel cars share each station. This would suggest 33 EVs share one charging location. This sounds really good for EV's.

That coverage is not homogenous. There are definitely areas with many charging points and petrol stations and places with few to none.  I live in a largish town (100K people) and we have at least 10 fuel stations, many EV charge points and the EV electric forecourt up the road which has capacity to charge 24 EV's a time. But I've been in other places where you have to drive to the next town along to find a fuel station.

Of course, you are likely to be taking 3 to 4 times longer to charge an EV then to fill up with petrol.

I would also say that it's likely that each petrol station has the ability to simultaneously fill 8 cars at a time and more likely double that.

Is that for the US? I've seen UK figures that suggest an average car here is driven for less than 1 hour/day - so that would be closer to 96%.

Example:- 1 public gas pump for every 1 gas powered passenger car. 

The uptake of Electric cars in the US is being limited by the small number of public charging points.

This statistic alone can provide no direct correlation, because of the differences in time taken to charge vs refill with liquid hydrocarbon based fuels.

What is needed, is a more in-depth analysis taking into account behavioural factors such as:

 - time(s) of day when refuelling is needed (there are surely 'pinch points', perhaps based on the 'daily commute' or 'daily school run' which can both be addressed by home/on-street and workplace/on-street charging);

 - approximate time taken to refuel vs time taken to recharge

 - the fact that some people (because of usage pattern) don't use full tanks of fuel to reduce fuel consumption ... comparatively, the weight difference between a charged vs uncharged battery is about 40 ng/kWh (using Einstein's equation) - which equates to about 4 micrograms weight difference for a large (100 kWh) EV battery. (This means that charge time is the factor that influences whether the EV is to be fully recharged, not the increase in weight of the vehicle making it less efficient)

etc.

Hello Andy:

Here in the US it is not unusual to drive 1 hour of more to get to work. It has to do with excessive housing costs around the location where one works.

There are some jobs that can not be done remotely even for IT programmers- example working in a fully secure site.

In the introduction of any new technology there are early adopters followed (maybe) by large sales to the general population.

Here in the US we have apparently reached the saturation point for EV cars by the early adopters, but the general population is not buying because of lack of public charging stations.

I recently received a flyer from our Electric Company stating that they would install an EV charging station at my home, for an addition monthly charge.

If this becomes an additional (optional) feature for all new homes, this could open the market for wider acceptance of EV cars in the US.

If this becomes an additional (optional) feature for all new homes

It's already a building regs requirement in the UK for new homes to have an EV charge point.(if it has a parking space) -e.g. for England https://www.gov.uk/government/publications/infrastructure-for-charging-electric-vehicles-approved-document-s

Andy:-

That's a real positive step! 

However if I was going to have an EV charging point added to my residence it would nave to placed outside. at a reasonable distance from the house, due to fire concerns.

Do you keep a petrol or diesel car near your home?  They are notorious for catching fire, and contain large quantities of highly flammable liquid.
