The cost of charging away from home varies hugely.
The big sites with ultra rapid chargers are between 79p and 85p per kWh.
The Tesla ones open to non Teslas are usually the cheapest at around 55p, less if you pay a subscription.
The point is, as has been discussed many times on here, if you use mainly public charging, a diesel or petrol car will be cheaper to run.
If you charge at home the majority of the time, with occasional public charging, it’s a no brainer, electric is far cheaper.
My BMW i4 costs around 1.8p per mile to run, a bit more in the cold winter months (2.5p).
So, when I’m on holiday and have to use public chargers, I don’t worry, because amalgamated over the year, the cost is still ridiculously cheap.
If you’re doing your 6 longer trips to Anglesey every year plus a few others, it will still work out much cheaper than your Niro on average over the year.
It’s a while since I crunched the numbers, but the point at which electricity stopped being cheaper than a petrol or diesel car doing around 40 MPG was at 43p per kWh.
That crossover point would be somewhat lower for your Niro doing 70 MPG on that journey, but it’s all about averages.
