Today I took our FIAT 500e to pick up some groceries. I rarely use it but it’s the ideal car for this trip: 25 mile round trip, destination is in a city centre, and parking in a multistory car park so neither ramps nor spaces aren’t generous.
Most importantly the car park is always very very busy, however EV charging is plentiful, right outside the M&S lift and the charging bays are extra wide, so I’ll usually pop it on charge even if it costs more than charging at home as it’s so convenient.
It’s often said that charging using a public charger is very expensive and especially if you don’t pay a monthly membership or subscription cost, and even more so when using the fastest ultra rapid chargers, so I thought I’d share the facts.
I charged using an ultra rapid 150 kW charger in a public charging station, at the full tariff rate as I do not have a membership or subscription, so this should be as expensive as it gets. Here’s what it cost and calculated cost per mile.
- 10.6730 kWh @ £0.48 kWh = £5.12
- Round trip average of 4.4 miles/kWh
- Typical consumption of 4.4 to 6.6 miles/kWh
- £0.48 kWh / 4.4 kWh = £0.109 per mile
Let’s compare that to an equivalent ICE powered car which I sometimes use on the same journey, a Smart ForFour, it’s 1.0 naturally aspirated, manual and relatively frugal. I’ve used an expected MPG based upon doing the same journey in the past.
- 4.55 litres @ £1.339 per litre = £6.09 per gallon
- EXPECTED Round trip average of 47 MPG
- Typical consumption of 42 to 58 MPG
- £6.09 / 47 miles = £0.130 per mile
So driving an ICE - even with the relatively low cost of 133.9p per litre of unleaded - costs 19.2% more than driving an equivalent EV using a public rapid chargers without a subscription or membership. In reality it costs more as I use VPower in the Smart.
That’s before factoring in the lower service and insurance costs in the FIAT, both of which are around half that of the Smart, and EV parking being free in that particular car park which today would have saved £1.80 per hour.
Some ultra rapid chargers will cost more, as will some petrol stations. However the reality isn’t anything like what some people say.
