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

[cal]

I’ve owned Tesla‘s for years and was amazed when I discovered how efficient and cheap an EV is to run. It was something Tesla promoted in their stores and I was real doubtful but the wife really liked the car and the acceleration was incredible so I bought in. Later when I actually got around to doing my own research… well I was pleasantly shocked. My monthly electrical bills were so close to the my pre Tesla bills that I had to look closer.

Back in 2014 my wife was visiting a skin cancer clinic in Portland OR. It was 62 miles round trip. It took 21kWh’s to make the trip. I pay 8.16 cents per kWh. All you do is multiply the number of kWh consumed by the cost per kWh. .0816 x 21 = $1.71. This realization changed my life. I would take the Tesla on every trip into town. Something that would cost me $5 in gas on my Tundra would literally be pennies on my EV. Truck annual milage dropped and we started racking up miles on the Tesla. When we took trips hotels would let us charge for free. It’s just another way to get us to stay there. A couple of bucks to let this guy charge was nothing.

Here is a snapshot of our current Tesla charge log. Pretty easy to calculate energy usage and cost.

I can’t find anything on my truck or the app that tells me how much energy I consumed on a trip or even what was added on the last charge. The FordPass app has a charge log section that is completely worthless. Telling me I added 4% or 25% tells me nothing about how much energy it took to get that %.

I know I must be missing it somewhere. This is actually a big deal in owning an EV. Impossible that Ford would have missed this.

This is what my ChargePoint Home Flex says. KWh and miles. Knowing miles to tenths would help. Then cross checking with the LTs estimated miles/KWh. The best way is the PUD meter. In our case I can turn off all garage power and read the meter as it is separate from the house meter. However when I told my SO two years ago that our MME would use $30/month... two months later she said.. ”The utility said our garage meter went up $30 a month“. My daily use is very consistent: 88-92 miles. And the miles/KWh very consistent at 2.6 Mi/KWh. The Mache was consistent at 4.1 spring and summer, 3..5-3.7 fall-winter.

If you have a standard range battery pack your usable battery pack is right around 100 kWh. If you have extended range it is more like 130 kWh. So if you use 10% of your battery that is either 10 kWh or 13 kWh.

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.

No comprehensive data reports are available from the Sync system, it would be awesome if Ford developed an all encompassing analytic for us to read the total KWH consumed, not just the traction energy stored in the battery.

In lieu of that I have a cumbersome spreadsheets to log my weekly miles, KWH fed to the Lightning via the FCSP using a very reliable Emporia Vue2 circuit monitor, being the data and statistics nerd that I am, it works for me.

I add my DCFC sessions with KWH & net costs (in Mass we pay sales tax on energy purchases at for-fee public charging stations)

I also log minutes sitting at DCFC stations for the time wasted factor.

Overall 12.5 cents a mile mean energy costs between home and away charging 20.1 cents a kWh, this will be increasing from August onward as we lost the cost advantage of paying by the minute in Massachusetts, home charging is currently 25.8 cents a kWh.

So far this year I've saved $1,442.63 in energy costs as compared the my former F250 Powerstroke Diesel.

I have not towed much this year, I recall one long haul event last spring but forgot to log the trailer miles, during those events my MPK drops to around 1.1

I'm sorry but that's not even close to accurate. And no utility company in the world would try to charge you based on a % of battery pack charge. They charge based on what you actually use.

If charge companies can figure out how much to charge you for a session, why can't I do this at home?

With the right tools you can, Emporia Vue2 energy monitor, this is only my home charging, no account for the DCFC or free public charging

Use the percentage that Ford says you used. Then multiply that by your battery size to get the kilowatts it took to charge. Standard range packs are 98kWh and extended range is 131kWh.

You're going to have to do the math. Ford doesn't provide the info you want.

For comparison, this is how the Emporia EVSE can report usage in the app. Gives the exact information the OP wants.

And this is what he would see if he installed the Pro Charger.

The Pro charger data logs are not 100%

I have several missing log days due to data brownouts at the FoMoCO mother ship's data center or the FCSP wifi comm's failures, my emporia is 100% reliable never missed a charge session.

We can show the dollar costs, but it does not handle seasonal energy rate changes, just one value, 25.8 is the current cost but it's been higher and lower.

* 2022 data is not close because the FCSP went into service last day of September, the Emporia Vue2 went online late November 2022

Has anyone using the Emporia service tried this?
I'm afraid to use it if Ford gets upset and locks my FP account again, I do not want to go through this again like I did last year.

I'm taking a chance testing this, letting Emporia connect, it's only showing the Lightnings SOC and projected range at the moment and that it's not connected at this time to an EVSE. If this locks me out of FP, I'll be pissed

You must not be familiar with math.

That will get your account locked again.

That will get your account locked again.

Thanks for the heads up, pulling it now, does not add any value that I can see

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.
