Exactly. These comparisons usually fail to take into account that EV charging goes like this:-
- Cheapest: Home Charging (7.5p to 30p depending on tariff and charging time)
- Low expense: Public 22kw Charger (28p to 40p)
- High expense: Public 50kw charger (44p to 60p)
- Very high expense: Public >50kw charger (usually motorways) (69p+)
Similarly, your Diesel could be anywhere from 141.9p per litre to 156.6p per litre.
A full tank from 10% in my ID4 (250 miles):-
- Home: £5.60
- Public 22kw: £20.91 to £29.88
- Public 50kw: £32.86 to £44.82
- Public >50kw: £51.54
A full tank from empty in my Renault Grand Scenic (500 miles) divided by two for comparison purposes:-
So yes, if you only charge at the most expensive 50kwh superchargers, currently diesel is better value.
Hands up all the EV users who have used a paid for 50kwh+ supercharger?
And how many times since you got your car have you used one?
For me, never and none in 8 months of ownership. I have used a public charger about 10 times. 8 of those were free. The rest 22kwh chargers for a short partial charge to get me back home.
