Cost to charge MY in Connecticut.

This can’t be a real question.

I’m in CA where electricity is also expensive. I pay $0.46 kWh at my house and $0.45 kWh at a supercharger. I drive a lot and up until last week I was not saving money and regretted buying this car at the end of January. The app says I’ve spent $27 more on electricity than I would have on gas. But now that gas is over $5.00 a gallon here, I think I’ll be coming out ahead. My last charge at a Supercharger cost me $20.77 and I drove about 96 miles on that charge.

I don't live there, but a quick Google tells the same story as just about most places, especially with gas going up again. If you can charge at home, you can save a good chunk of money. Rough math is around like $8 for electricity assuming $0.28 per kWh vs. $13 for gas at $3.52. (That's assuming 28mpg for your average CUV over 100 miles) Supercharging is about even with gas, depending on how often you need to use it. Utilizing Time Of Use rates on your electricity can save more too.

I would use the following thinking… “How much does it cost me to drive per mile … from a fuel perspective” Then take your electric bill - $0.32 per kWh ? Then take your average Tesla Model Y efficiency - 4 miles per kWh ? … so $0.08 per mile? And then maybe take an ICE crossover … RAV4? 27mpg … $3.50 per gallon right now … $0.13 per mile? Make a little spreadsheet sheet maybe so you can mess with the cost variables. I think even with those INSANE electric costs you’re still doing better. But you probably fall to like a Prius or something. Honestly, Solar starts to make some sense in these scenarios. We got a fairly large system in like 2015… saves me gobs on fuel up here in NH with 3 EVs.

California here. Ten years ago we put solar panels on the roof. Haven’t paid for electricity since. We generate more than the house needs and can charge our MY (for free) enough to drive 10,000 miles/year.

96 miles on 40kWh is extremely inefficient driving, isn't it?

Ouch, $0.46 at home? I am paying 5.6 cents at home, and from $0.31 at Supercharger in Texas. Gas is $3.19 here. We average about 289wh per mile. So at home we pay 1.6 cents per mile, while Supercharging is about 9 cents.

Maybe I’m wrong but I am thinking that works out to $0.21 cents per mile. I’m basing that on the car being at about 20% when I stopped for charging and being at about 20% when I got home. My speed was 75 mph the entire trip. I don’t see any place in the app that will give me more detailed info but I’m sure it’s there somewhere. (I looked at the receipt and it was actually $0.43 kWh at the charger so I got 48.3 kWh)

I think it really depends on how efficiently you're driving. Like on your car it will give you a number such as 300 wH/mile. So just do the math 300 wH/mile x 1/1000 kWH/wH x $cost per kWH That will give you price per mile Similarly take a car you've driven before assume 30 mpg $cost per Gallon ÷ 30 mpg = cost per mile And compare Price of gas fluctuates electricity not so much So have a spreadsheet to make it easier to compute

We have a complicated bill here. Right now peak is $0.46 and off-peak is $0.43. However then we get something called a “baseline credit” but no one seems to understand how to calculate that. On top of that, they changed their billing in March so now we pay a base service fee but the kWh price is going down. I haven’t received a new bill yet. I want to cry when I read what people in other parts of the country are paying.

Your math seems right, but you're only getting 2 miles/kWh (or as it's shown in the car \~500wh/mi). I don't know what model you drive, but I'm averaging \~225Wh/mile in my Juniper long range RWD (which is admittedly a relatively efficient model) Are you blasting heat/ac, driving with a ton of acceleration and hard braking?

I'm in Connecticut. Here is the hard truth. In the months June to September, I charge at the waterbury supercharger because it's cheaper than charging at home. With Eversource and their BS charges, the more you use at home the more they charge you for "delivery" Typically it cost me on average $125 per month extra to charge weekly at home, but in the summer months it jumps to close to $200. I daily work commute is 22 miles, so its not that much.

In Connecticut we pay close to that.

It’s a 2026 MY Juniper long range AWD. Not really using heat or AC as we’ve had beautiful weather. I do like to use the heated seat. There’s virtually no traffic where I live so no hard braking or accelerating. That whole trip was actually on FSD. Thank you for pointing this out, I’m going to dig into it more and try to learn more about my cost per mile.

Yeah, I hope you get to the bottom of it, you should probably be around 250Wh/mile worst case given AWD compared to my RWD. Energy efficiency is this biggest driver of cost savings imo.

How big is your house? How much electricity do you use per month in summer months?

Except the Rav4 is going to be about 35 mpg like our Highlander Hybrid and you don't lose about 30% of your range when it gets to be in the low 30s and below.

Whatever the math is - the method is sound.

Exactly what I did. We pay .29 per. Solar panels will cover 102% of expected need and pay back in less then five years. Solar folks also connecting us with a cpa so we can still get the 30% federal credit. It’s got to do with setting up an LLC that purchases the panels to get the deduction.

Unfortunately, electricity cost only goes in one direction. While generation might vary slightly the service/delivery costs only go up.

Daughter has a MY in CA and lives in an apartment. Before the Iran conflict it cost more to charge than gas in the Bay Area.

Yes, but people in New England need to understand that winter driving is very expensive. The other thing that's a bit hard to calculate is the cost of preconditioning while plugged in. That's not recorded by the car as energy used whereas someone warming up an ICE-based vehicle would see the MPG loss for doing the same. What we do is look at our electric use for the charger (Tesla records this) and then use that with miles driven to get a more accurate cost number. Of course, if you go to a SuperCharger that would need to be added in.

Exactly.

> Yes, but people in New England need to understand that winter driving is very expensive. Yeah, 4 miles per kWh is a joke. Maybe in the spring and fall driving 45 mph and less. Going down the highway in the cold winter it's more like 2 miles per kWh.

> Are you blasting heat/ac, driving with a ton of acceleration and hard braking? ... > My speed was 75 mph the entire trip - > I'm averaging ~225Wh/mile Not when driving over 60mph you're not.

I don’t know why you think it can’t be a real question. There are some areas in the US where electricity costs actually exceed gas costs for some cars. In Kansas until recently, using a supercharger was equivalent to an ICE vehicle getting 20mpg based on local gas prices.

Yes. In CT and MA ($0.33 per kWh) or any other high cost electric state, you will have a lower cost per mile for a regular hybrid. Skip the PHEV and EV, at least for a new car purchase, they will cost more up front and to operate. That being said, I had a PHEV two cars ago and now I am in a Model Y Performance. It is basically cost neutral vs my previous non-hybrid sporty car but delivers performance at or above gas cars that would have required premium fuel and a major drop in mpgs. For me, I get higher performance for the same cost as a mid-performance gas cars for the same running cost. Most people don’t care about that though, and for that scenario, go hybrid and save money up front and per mile after that.

Cost to charge an EV is very simple math. Figure out your cost of electricity. Let’s use $0.35 per 1 kWh for this example. Figure out your EV miles you can drive per 1 kW of electricity. Let’s use 3 miles per 1 kWh for this example. The simple math is that every 3 miles costs you $0.35 in electricity and every 1 mile costs you $0.12.

Thank you! That's the kind of first hand response i was hoping to get.

You're welcome bud After all, it is still cheaper than owning an ICE vehicle.

Did you sign up for CT energize program to reduce delivery charges?

It is a real question. We pay $0.34/kwh in CT. So comparing to gas makes sense.

Thank you all! So basically in real life its possible to safe a small amount of money but not a huge amount. As expected.

About 1500 sq.ft., no AC, pool, etc.

How much did the panels cost and are they paid for now? Where I live I just can’t yet justify it, it would take 30 years to pay for itself partly due to the connection fee. Our electric is currently $0.10 kWh.

When installed they said the cost savings from electricity would crossover at 12 years. But rates DOUBLED so it only took 6 years. (We paid cash, if that matters. 16 panels (older tech, less generation/panel) and it was about $15k before tax incentives.)

Ah that’s nice. I run the numbers every year but they also keep putting the connection fee up so they don’t come close, yet.

I pay .33kwh in Massachusetts. We avoid charging at home if we can help it, and I charge at work because there are no delivery fees so the electricity is less, about .15kwh it costs me about $7 a day to stay topped up (10 hr shift left charging) so home charge would be $14. I paid $50 every 2 days when I had my Nissan Pathfinder and gas was like $2.50 at the time. Gas is hovering around 3.75-$4 right now so it's a no brainer even with electric prices where they are gas is worse.

So multiply 0.34 * size of the battery in the car you’re looking at. That’s roughly how much it will cost to charge it from 0 - 100. You’ve got all of the information available to you.

especially if you're in California with pge lol

Florida here. At $0.10 you may never get a benefit from solar other than having your own electricity if connected to battery backup. It is around $0.15 kWh for me but when I installed solar (27 panels, 3 batteries), price went down to between $0.035 to $0.10 kWh depending on how much sun for each given month. More sun, cheaper electric use. If it retailed here for $0.10, which is dirt cheap, it would be hardly worth it for me.

Makes sense. The connection fee is $35 a month too which is a big hurdle.

My 2023 MY uses around 240-330 watt-hours per mile, depending on temperature and driving conditions. About 3 miles of range per kWh, more or less. So you could be able to use that to figure your per mile electricity costs based on what you pay, and then compare that to your gasoline costs per mile.
