How much cheaper to run are electric vehicles ?
I was reading about the new MG ZS EV:
“ ... rapid charged to 80% in approximately 40 minutes* from a 50kW DC fast charger.
Charging can also be done at home on a 7kW domestic charger, where a full charge can take approximately only 7 hours...”
How does the price of electricity compare to the cost of buying petrol? (Approximately)

Seven kilowatts for seven hours is 49 KWH or 49 electricity "units".
The cost varies from place to place but generally somewhere roughly 0.12 per unit.
That's just under 6.00 for a full charge, which the ads say gives a range of 160+ miles.
My present car is rated 38 MPG. As UK prices, one gallon costs (for around 38 miles) costs somewhat more than a full charge (160 - 230 miles) with that electric car.
Very roughly that puts it at around 5:1 ratio under mixed driving conditions.
It would be far better still for city driving, probably 10:1 or even 20:1, as the range per charge goes up with the electric one at low speeds, while MPG drops drastically with a normal engine in city traffic.

To add here, there are free charging stations around....not sure about for this particular vehicle, but they exist. I've never seen a free gas station...

Look around internet forums for actual mileage that people obtain from the vehicle. While the advertised range might be a certain amount, that's probably on flat ground at slow speeds, with the heater and air conditioner off. Everything makes a difference in an electric. Sorry for the US measurements, but on the freeway, we might get 1 to 2 miles/kWh, while driving locally at 25 miles per hour or less, we get 5 miles/kWh.
Also, not unlike AA batteries, the ratings are when the batteries are brand new, and capacity deteriorates with recharging. A 100% charge reduces battery life, so a conservative owner who does not need the range might charge only to 80%. Fast charging generates heat, which hurts the batteries, also.
All this said, we have an electric, and it's cheaper by far to run than our gas (petrol) hybrids. Also, no oil changes.

That varies a LOT from locale to locale.
Consumer Reports has done an evaluation of total cost (relative to the U.S.)
- cost of electric car plus cost of driving car over a typical car lifetime
- cost of regular car plus cost of driving car over a typical car lifetime
and concluded that the electric cars are, overall, more expensive.
Even though they are MUCH more efficient in terms of cost per mile
the initial cost overcomes that savings.

Electric costs vary across the world........ however with electric vehicles electric costs are not the only issue, many insurance companies charge far more for insurance, emergency services ( police/fire) will not deal with them if there is an accident requiring you to get vehicle rescue insurance from one of the companies and if you don't have that you would have to pay the high cost for them to deal with it when the police/fire service call them, you have to use the manufacturers garage for services as many independants do not have staff who are electric vehicle trained mechanics, so manufacturers are double ( or more ) costs for servicing, repairs, maintenance and the batteries will need replacing so you either will be purchasing new batteries for it as they do not last for ever( costs about the amount for a reasonably priced second hand car) or renting new batteries ( costs are very high) or trading it in to get a new vehicle

Electricity rates vary depending on where in the world you are located. Google your local electric company and see if they have their rate structure online.
