Does anyone know how to calculate the actual cost of a Lightning’s energy consumption?

[trev5150]

And even that 10% is negotiable depending on the charger, ambient temp and battery temperature.

It’s pretty darn accurate in that it tells you the kWh you consumed. The only change is to add about 10% to that number to account for charger losses When charging at home.

Not even close. It does not tell you actual kWh consumed. It’s an approximation. Consumers would go nuts if their power company billed on something as ludicrous as this. It doesn’t tell me the actual kwh consumed. And having to add in another 10% erodes it even more. You’re not starting with actual energy consumed. You‘re guessing. Miles/kWh is not even a static figure. It’s a flow rate based on speed and load. The number an average of the high and low m/kWh measured. Goes up under low speed and higher when you accelerate.

Let’s apply this to an ice vehicle. You have a 20 gallon gas tank. At the end of a trip you fill up and it tells you you’ve added 34% back. Well gee did you start with a full tank or 5 gal? Did you fill all the way up or only to 80%? Trying to do with with %’s is just not going to work. I just disagree.

Look I get it if Ford has neglected to give us an easy way to monitor energy consumption. Maybe an update later.

I was looking for someone to point out a screen on the truck or the app I missed. Guess I was wrong. It’s just not there.

It really shouldn’t be this hard.

If you are wanting kWh used, the Charge Station Pro has this screen in the app. Note the kWh is the total of the energy put in the battery plus losses. Other chargers show similar.

And you can get pretty close to this number using the math we have been mentioning but I'm not going to explain that again. There are a lot of other threads where folks have shown how to calculate energy consumption using start/end SOC and battery size (does not rely on miles/kWh, speed, etc.)

Still haven’t connected the Charge station pro. Maybe a good reason.

Your first post proclaimed how wonderful the Tesla was, but it also wasn't reporting the energy from the house, it was reporting the energy after loss. So it was wrong.

During the session, you can see the actual kWs used. Once you end the session, you cannot. So, go look before you unplug.

Or, buy a smart EVSE. My JuiceBox chargers have history going back to the beginning of use.

Thanks but where can I fnd this info in the Ford world? I only have the mobile charger. I have the Procharger wall adapter but haven't bother to install. Because so much is dependent on driving style, weather, elevation changes it's not very easy to say what my cost would. be

It shouldn't be necessary to use a third party charger to answer a cost question like this. I've got to believe its' somewhere on the truck or somewhere in the app.

In the Mach E world we used miles/% of charge thus my LT will crank out 3.2 miles per 1% of charge or 32 miles at 10% and that compares favorably with 323 miles of range at 2.6 Mi/KWh.

This is most sensitive measure I’ve used. And since I drive the same route daily, uncannily repeatable.

I’m not following, I just leave my Trip 1 the same way I leave my Trip A on my Tesla as never being reset and it shows a 2.1mi/kWh over the life of my truck. With the odometer reading that comes out to 6168 kWh consumed for truck efficiency.

in the same token 1/2.1 = 476Wh/mi for the Tesla familiar, which is my preference for monitoring consumption.

I save trip 2 for trip specific info and I just do the same thing. # of miles travelled divided by mi/kWh = kWh consumed.

Am I missing something? Based on the trip meters there isn’t info on the Tesla that I can’t figure out on the Ford….

Thanks for responding. I'm curious what you think the 2.1mi/kWh means. It's an average rate of consumption not an absolute number used. When you go faster it falls. When you go slower it goes up. You're using an average rate to ...

You know, we'll just have to disagree. I don't feel I should have to do calculations for something like this.

My original question is answered. There is no page or tab that just gives consumption/trip or charge directly. I'm ok with that. In the scheme of things this is really not a big deal and I love the truck. Can't wait to see what the other boys bring to the table though. More importantly how quickly anyone can get one.

I got mine now!
