He said a Latte, mentioned the ingredients being beans and milk and feeling sorry for people that don't have a coffee machine, so it's not likely to be an instant coffee. His analogy gets better when you consider the coffee machine probably cost about the same or more than a home charger.
Also the purchase price of electricity for Sainsburys isn't going to be the same as Octopus, for a start you are comparing a day price with an overnight price (which is subsidised by an inflated day price). Octopus also makes a loss which is ok in their growth model, Sainsbury's shareholders wouldn't like that.
Except
@btc1k was making an analogy based on this post:
I'm sure it works ok, but it costs 10x (TEN TIMES) the price of home charging with Octopus at 7.5p, so I feel sorry for the chaps who need that.
..where that person is talking about essentially not having ANY ability to make coffee at home, i.e. not having a kettle, never mind a coffee machine. The comparison therefore is specious because it's not like-for-like. Someone who has access to a home charger can pay 7.5p/kW for
exactly the same electrons (aka cup of coffee) that they would get at a coffee shop, for 75p/kW.
The rest of your post is white noise about the cost of electricity for Sainsburys and whatever their shareholders might think which has got absolutely nothing to do with how much it costs someone without access to a home charger to run an EV, relying solely on
coffee shop coffee public charging. That person cares not what economics are involved in Sainsburys providing that service, only that it costs X and what that means in terms of "cost to run my EV".
I do. They're not rare and a decent one can be picked up from £300...
Fast chargers have significant capital outlay and so complaining the price of electricity is not the same at home completely ignores this fact.
It's a great analogy because the coffee machine is capital expenditure which effectively is repaid over the life of the machine, divided by the number of cups of coffee dispensed...
But a fancy coffee machine is not equivalent to "home charging facilities" though. If someone can't charge their car at home, it would be more accurate to think of them not being able to use a kettle, and therefore not being able to make coffee AT ALL at home, and having to buy coffee (in whatever form that takes) from coffee shop, paying the inflated price. That is who
@WllXM is feeling sorry for.
(For what it's worth I have a beans-to-cup machine as well, but still buy Costas etc when out and about because I don't have access to my coffee machine at home when I'm out and about and need coffee. i need coffee a lot more often than I need to charge my car
As a consumer I honestly don't care how much it costs Sainsburys et al to provide public charging. I care what it costs me to run an EV. If I had to rely on public charging, as many people would need to do with infrastructure being what it is, then it would be unsustainable based on these prices, and availability.
