Dull men's club? Petrol/Diesel comparison

[bedsev]

I'm not sure if I should be posting this here or in Dull Men's Club... but I did a little Excel that can calculate charging costs vs petrol/diesel equivilents.

So this tells me that in almost all cases charging, including public charging, is cheaper than Petrol/Diesel.

Only the 50kwh charger at Tesco is a quid more expensive on a full charge from 30-80.

This is based on 1.47 per litre (current diesel price to me), average 3.5 miles per wkh driving in my MG vs an ICE at 40mpg.

As a fully paid up member of the dull mens club or as we are known in some quarters, the Excel Owners Club, I also have a sheet comparing break even points on fuel costs of EV vs ICE. It really depends on how much you pay per unit of fuel, be that a kW or a litre and the fuel efficiency of the vehicle.

No shit, Sherlock!

Rolfe, language! 3 points. ???

Not a banned word. If someone wants to ding me for "mild swearing", I will appeal on the aforementioned grounds! ?

My last diesel vehicle cost ~A$13/100km to fuel.

My MG4 over first 10 months cost ~$4/100km to fuel.

Home charging though is stupid cheap, it's travelling away from home that bumps the overall cost up.

In July my charging at home cost A$0.28/100km.

Is that taking into account, the export money you didn't get?

Yep. Breakdown including foregone feed-in credit:

120kWh free, that's cheating. We don't have an option like that. Best I could do is $0.08 but then I'd be charged $0.58 for running the A/C in summer. I haven't worked out yet if that's a cheaper option.

At the moment, we aren't doing too bad with a solar/grid mix.
Trouble is I don't have a distinction from what goes into the car and to other power points in the house. So I can't work out exactly how much power is going into the car.

Owning a diesel which uses 14.7L/100kms costs me $29aud/100kms.

Owning an EV which uses 15.6kwh/100kms costs me (assuming 85% efficiency & not using solar) $5.7aud/100kms.

Being a Dull Man, at just under 6,000 miles I started keeping a record of all our charging and it's cost at the time.

I'd say 85% of our driving is beyond range, so there is a lot of out and about charging in here.

Car is just comping up to 31k

MG4 cost miles MG4 per mile petrol eqiv at 45mpg
£1,158.69 24898 £0.047 £4,032.37

Putting the info into CODE tags to help line things up:

MG4 cost  Miles  MG4 per mile  Petrol eqiv at 45mpg

Thanks SG, I should know better but how's that achieved in this BB?

[ code ] and [ /code ] are the wraparound tags (without the spaces), and then just use the Preview option to make sure the spacing is right.

Elementary, my dear Watson

 

[wattmatters]

These are our totals to date:

Not sure how the 11c cost snuck into the free charging, will have to look into that.

Looking at this reminded me of the first 6 months of EV ownership, keeping track of everything.
Then only keeping track of what I used to ferry the kids around (to claim back from a joint account)
Now using a smart integration to automatically debit my account to pay into the elec bill when I charge at home (rarely)
I don’t even care whether one is cheaper than the other because there’s no point anymore, I even stopped claiming back from the shared pot those 70p here and 25p there. ?
