Tesla Wall Connector - Data

[Paul1]

I have seen some articles online about Tesla allowing you to add your Wall Connector to the Tesla app as a device.

Does anyone know if there is a way to get the data out of the Wall Connector such as, kWh used weekly/monthly/etc. to charge the vehicle or if and when the device is getting FW updates?

If it's connected to your local network then you can get info out via its REST api.
It's supported by home assistant too.

Imagine if Tesla made it an option to list your charger in their app and let people charge at your charger when it was available.

Price here is dynamic, but could be set to be "Actual cost + a small overhead for the owner + a small fee to Tesla"

Even if the owner of the charger was only paid in "charger miles" at the Super chargers it would be a great deal.

I would love to have a Tesla Charger that would actually be able to make me some "money / free miles" while letting people charge at it for less than most public fast and destination chargers (Atleast in Denmark)

Only downside for Tesla is offcourse, that they would make less money on cars using their SuC network.

For me...In summer it would be a nice little addition as i have solar panels, so instead of selling the surplus solar power to the grid i would be able to sell it and make a little more profit compared to selling it to the grid.

They do - but you have to have 6 or more Wall Connectors.

Yes, but that is not for private people, this is for, for example a hotel to offer destination charging to their costumers.

If i had to go visit someone living more than 50% of the battery away from me, for some hours, i would love to be able to park my car "down the street" in someones driveway and charge it there, instead of having to stop in the way home at a SuC

Also i am unsure if they would be able to do dynamic pricing, if not you would have to set the price so high that you were sure the charge was covered, this would make it not economical for someone to use it.

The idea is here, that when electricity is cheap here, it is because there is a lot of it, so this would be the best time to charge...Not very good if the price is always high because Tesla only does a fixed rate.

That's true, it is geared towards commercial. It *seems* like you could still put 6 of them at your residence (if you have the parking spaces) and use their software and system to collect revenue, but they won't list you in their maps without selling goods/service and having regular house and employees.

Personally, I'd be leery about home chargers listed in the navigation. You can find those on plugshare though.

Yes, but then you need a different charger that has its own "payment" ecosystem.

I have a Go-e charger, it has no provisions to enable me to charge people for charging at my charger so i am certainly not going to list that.

Theoretically i could list it, and then have people knock on the door and then i could unlock it and let them charge, but honestly that would limit me to only have people charge here when i am home, but i would rather they charge when i, and the car, are NOT at home.

Listing an "always open" charger on Plugshare would be really silly, as i would be paying for other people's charging.

Agreed, but many people list theirs just to help other EV drivers. I think even listing one that you can charge for is silly... how much could you really profit from it in a month? And would that really be worth havibg to content with strangers for your own charger?

It made more sense in the early days when a handful of owners were dealing with a handful of charging locations. People could get into a bind and seeking out a residential unit might be your only hope.

Would not make me a millionaire, but with the price structure in Denmark it would actually bepossible to make some money and at the same time help someone out.

Tomorrow i am going to go on a company related trip, i need to stay at a hotel, this hotel has destination chargers but the price per kilowatt is 0,67 USD, at this price it would have been cheaper in "fuel" to just keep my diesel car.

About 0.6 miles from there, a private accountant company as some destination chargers they decided to make public, these "only" cost 0,29 USD so i am going to park my car there for the night and walk to the hotel (I always walk anyway, trying to not gain the weight i recently lost).

Here in Denmark for normal consumers we pay 0,19 USD just in taxes for every kilowatt, so if the electricity at a particular time cost, lets say 0,11 USD, i pay 0,30 USD per kilowatt, combined.

But if i at that time sell a kilowatt i only get the 0,11 USD (And the price is even lower because the company i sell to, also has to make a profit).

So basically...If someone charges at my charger right at that time, and the electricity comes from my solar panels, i can charge them, lets say 0,40 USD per kilowatt, i only lose the 0,11 i could have sold it for and i make 0,29 USD per kilowatt.

I would theoretically be making 3,19 USD per hour, more than if i just sold it.

And remember, i am competing with the destination chargers in my city that at the minimum charges 0,60 USD and bear in mind, this is only a few, most are more expensive.

In my city there are even destination chargers that charge 1,25 USD per kilowatt. I honestly do not know who would want to charge at those, but i guess it is mainly tourists that are not paying attention the the prices.

So yeah, while it does not make me a millionaire, it would possibly make a bit of money, and just like the charger i will charge at, tomorrow night, i am helping out some fellow EV owner, charge their car at a price that actually makes it cheaper per kilometer to drive their car, compared to diesel.

You mean per kilowatt-hour (kWh)? Kilowatts and kilowatt-hours are totally different metrics.

 

[father_of_6]

price per kilowatt is 0,67 USD

charge 1,25 USD per kilowatt

That's outrageous!

 

[hmadsen]

That's outrageous!

Nevertheless that is the prices they charge everywhere here.

At a hotel i would even say it might be a "convenience charge" where you pay more because of the convenience of being able to charge where you are staying, but all of the chargers in the city where i live are also charging just about this rate.

The cheapest public charger in a 5 mile radius of where i live is actually the Tesla supercharger, they charge 0,26 USD per KWH when charging at the off-peak price (A wee more expensive between 6PM and 10PM)

Tonight the Tesla is going to be charged to 100% because i am going on a trip to the edge of the range of the car, tomorrow and tonight the price of the electricity is, rather unusually actually "free" so i only have to pay the 0,19 USD that is the tax.

Break even point for electricity vs diesel for my previous car comes to :

Diesel car 20 kilometers per liter, liter price right now 2 USD so basically 1 kilometer cost 0,10 USD purely speaking about the "fuel cost"

Tesla does about 5 kilometers per kilowatt at motorway speed, so i need 4 kilowatt to go 20 kilometers.

So anything below 0,40 USD per KWH is cheaper, so tonight i charge at about half the cost, compared to diesel.

Oh and i paid the equivalent amount to 62.800 USD for my Grey Model Y LR .... And no incentives or tax deductibles.

So...Yes, everything about car ownership in Denmark is insane.

Yeah and EV's only have 25% VAT added to them, if you buy a petrol or diesel car, there is also extra registration tax of basically 150% of the car price from the manufacturer...And the VAT is added after that, so you also pay VAT on the registration tax)...
