How much does it cost to charge a large electric SUV?

Work out what it costs to charge an electric car at home — per top-up, per year and per 100 miles or kilometres, including the energy lost on the way into the battery.

Using the Canadian average of 15.57¢/kWh — Hydro-Québec's annual utility price survey, rates in effect 1 April 2025.

Bigger battery and worse efficiency compound: a large SUV can cost close to twice a small hatchback per mile, not just per charge.

Your region Rates vary widely across Canadian — picking yours makes the answer far closer.

Your car

Usable battery size

kWh

The usable figure, not the gross one — manufacturers quote both, and a few kWh are always held back to protect the pack.

Energy use

kWh/100 km

Real-world consumption, which is usually worse than the official figure and noticeably worse in winter. Leave at 0 if you would rather skip the distance figures.

The charge

Charging to

80% is the usual stopping point: charging slows sharply above it, and sitting at 100% is harder on the battery.

Charges per week

Your tariff

Your electricity rate

¢/kWh

If you charge overnight on an EV or off-peak tariff, use that rate — it is often a fraction of the standard one, and it is the single biggest lever on this answer.

Charging losses

Energy that never reaches the battery. Home AC charging typically loses 8–12% to the onboard charger, the cable and keeping the pack at temperature.

This top-up costs $8.30

Charging cost per year $1,295

Cost per 100 km $3.98

Range added (km) 209

A full charge would cost $13.84

Drawn from the wall 53.33 kWh

What drives the cost

Large electric SUVs stack two costs. The battery is bigger, so each full charge moves more energy, and the car is heavier and less aerodynamic, so it uses more of that energy per mile — often 23 to 28 kWh per 100 km against 15 for a small hatchback.

Per charge that looks like a moderate difference. Per mile it is close to double, and it is the per-mile figure that determines the annual bill. On a standard tariff a large EV can approach the running cost of an efficient petrol car; on an overnight rate it remains comfortably cheaper.

How this is worked out

Charging cost is the energy you put in multiplied by your electricity rate — but the energy you put in is not the same as the energy that reaches the battery. Some is lost in the car's onboard charger, the cable and keeping the pack at temperature, and your meter counts all of it. So a 60 kWh battery taken from 20% to 80% needs 36 kWh at the battery, but around 40 kWh from the wall at a typical 10% loss.

What this assumes

Charging losses of around 10%, which is typical for home AC charging. A slow 3-pin plug is worse, a wall box on a warm day is better, and cold weather is worse again.
One flat electricity rate. If you charge on an off-peak or EV tariff, the rate you enter matters far more than anything else on this page — overnight rates are often a third of the standard one.
Real-world energy use, not the official test figure. Winter, motorway speeds and a full car all push consumption up, often by 20–30%.
Home charging only. Public rapid charging typically costs several times as much per kWh.
The rate filled in for you is an average that spreads fixed charges across a year's usage, so it sits above what one extra unit really costs. Entering the unit rate from your own bill gives a closer answer.

Questions

Does a bigger battery cost more to run?

Not by itself — a bigger battery is just a bigger tank, and you pay for the energy you use, not the capacity you own. What costs more is the weight and frontal area that usually come with it, which raise consumption per mile.

Why is the wall figure higher than the battery figure?

Because charging is not perfectly efficient. The car's onboard charger converts AC from your house into DC for the battery, and that conversion, the cable and the battery's own thermal management all take a share. Your meter bills what left the wall, so that is what this calculates.

Why does it charge to 80% rather than 100%?

Because that is what most people do with a nickel-based battery. Charging slows sharply in the last 20%, and an NMC or NCA pack left sitting at 100% degrades faster. LFP packs are the exception and are meant to be filled — if your car has one, its own page here says so. Set both fields to whatever you actually do; there is a full-charge preset if you want the other number.

Should I use my normal rate or my EV tariff?

Your EV or off-peak rate, if you have one and you charge overnight. It is by far the biggest lever here: the same car on the same mileage can cost two or three times more on a standard rate than on a dedicated overnight one.

Does this cover public charging?

No. This is home charging. Public rapid chargers are priced per kWh at a much higher rate, and often add a connection fee, so the cost per mile can be several times what you see here.
