Hi everyone, I’ve been driving my 2024 Niro EV since March 2024 and I’m trying to figure out the cost of charging it at home using the Level 1 charger. I’m in Canada, though I don’t think that makes a big difference for the math. Here’s what I’ve calculated so far:

The EPA says the battery is 64 kWh, and the range is about 407 km.

I’ve driven 10,000 km so far, and my electricity rate is $0.104/kWh.

(10,000 km / 407 km) x 64 kWh = 1,572.48 kWh

1,572.48 kWh x $0.104/kWh = $163.54

So, roughly $21 per month over 8 months. Does this sound right?

You won’t always get 407 km per charge (you’ll see much lower range in winter or if you drive faster), and sometimes you might get more. If you’re budgeting, I’d double the estimate just to be safe.

No worries, the range definitely drops in winter, but I factored in about $40 per month when comparing it to my previous car costs. So far, I’m below that, at least based on my power bills before and after getting the EV.

The problem is we don’t know your exact power usage. If your car uses exactly what it’s rated for with no charging losses, then your estimate looks good, but that’s not always the case.

Do you have an average Wh/km or any data like that? That would give a more accurate charging cost.

@sorphia
Thanks for pointing that out! How do you find Wh/km? I was just calculating based on the total km driven, assuming the 64 kWh battery would give 407 km. But yeah, it’s probably not super accurate.

The problem with that method is that your 64 kWh battery probably didn’t actually give you 407 km. That’s the rated range, not necessarily what you’ll get in real-world driving. Your car should have a display showing your actual usage, similar to how new gas cars show l/100 km.

This is a good rough estimate. But you should look into how much of your battery capacity is actually usable. Setting up a simple Excel sheet could help you track this by recording things like how much you charge (e.g., from 43% to 80%). That’ll give you a better idea of the kWh used.

The most accurate method would be to get a Level 2 charger that tracks your energy usage. But the Excel sheet is a good alternative.
