What’s your Consumption Rate?

[BrockN]

Interesting. It looks like a "rated mile" is about 373 Wh, if my arithmetic is right. And you're only about 3% over. That's impressive.

I made a document in numbers that tracks all of that info

I’m at 2.07 M/kWh but it seems pretty high compared to others.

I use a custom profile with beast acceleration, relaxed suspension, and prefer higher suspension. I only stomp on it occasionally and let FSD do 95% of my driving. My life time efficiency used to be about 107% but I had a winter family road trip at Thanksgiving from Seattle to Idaho that really dropped it but it has been climbing back up. I constantly get over 110% for a typical work day. It's all in how you drive.

Im averaging 300-350wh/mile

good for a truck anyway. Not so good for an EV relative to EVs in general

From your chart, you listed 2.07 M/kWh which is equivalent to 483 Wh/mile, no?

Thats this month. Ill take a look at the efficiency profile from the car later and compare. The calculation is based on (total kwh added that charge session)/ (miles since last charge). Not the most perfect way to calculate the efficiency

Why would you compare it to 'EVs' and not 'full sized trucks'? Of course it uses more energy than my Zero or my friend's Leaf.

This is a fair point.

the thing i found most interesting is that high electricity prices make the equivalent cost/gallon of “fuel” much higher in an ev. The conversion is 33.7kWh is roughly 1 gallon of gasoline. I pay around $0.37/kWh delivered at home making an equivalent gallon of fuel ~$12.47/gallon, which really digs into the whole “fuel savings” part. Fortunately i can charge for “free” at work sometimes. (I have to pay monthly for parking anyway)

One of the columns i was going to make was to compare the avg mpge to the mpg for an f150 (which from what i was reading gets avg 17-20mpg real world) and a subaru forester, which is another car i was considering (25ish mpg)

I used an estimated 300 miles of “range” between fueling and that helped level the playing field a bit. My CT consumes the equivalent of around 3.37 gallons of “fuel” to go 300 miles@ $12.47/“gallon” = $42.18(Gasoline equivalent)

f150 consumes 17.65 gallons @ $3/gal =$52.9

subaru consumes ~12 gal @ $3/gal = $36

so in all, for what the CT is, compared to other things i may have bought, falls right in the middle.

i think the algorithm in my chart only will accurately reflect at the end if the month? I also excluded data from charges that i didn't drive much between charges (<5 miles) because it skewed the data lower. Especially if the number was 0

Holy crap! You pay $0.337/kWh at home? Who is your electrical provider? That's highway robbery by people who are inept at delivering electricity in an efficient manner. Our rate is $0.11/kWh and that includes delivery (monthly meter fee is only a few bucks). You pay almost as much as they do in Hawaii where they burn dirty and expensive oil to make electricity.

And if 33.7 kWh of electricity equals one gallon of gasoline, then I have a high performance 4x4 pickup truck with over 16" of ground clearance, running 35" tires with a payload capacity of 2500 lbs. and great off-road chops that gets 88 MPG combined City/Hwy. That's just incredible!

A comparable gas truck would only get 11 MPG combined City/Hwy, about 1/8th the efficiency. BTW, where I live, that 33.7 kWh of electricity is a bit cheaper/about the same price, as a gallon of gas (Western Washington).

Yeah. I often times pay more in “delivery fees” than the actually electricity i use, sometimes by a factor of 2. Ive called National grid and they have said “if you dont like it, talk to your state legislators.. they are the ones who approved it”. The same for natural gas too.

i agree with both you and @Crissa that when you compare it to gas trucks, its no contest, especially when youre talking a ford superduty or a ram 2500. I think the CT falls somewhere between a 150/1500-250/2500 class truck in terms of various capabilities

Oh, I see, you live in Massachusetts? You are getting screwed over by your utility provider, the regulator, the British company that was allowed to run an electrical monopoly in the US, and the high taxes on electricity levied by your state and local governments.

I recommend you put your locality in your profile so I don't have to ask your location next time. Massachusetts has some of the highest rates of all the mainland 48 states. Just across the border in Qubec electricity is about 1/4 the cost. There is no reason why the cost of electricity should change significantly as it crosses the border.
