Supercharger Costs

[holmesm1]

I was looking for recent posts about supercharger costs and found no centralized location for that data. So I am going to post my data from this year and maybe something will come of it. I skipped any duplicate sites as the purpose is to document charging rates at the time and not my personal usage. Will update this post with more sites later this evening or tomorrow.

Date	Site	City	State	Rate/Kwh
10/16/23	Piedmont	Piedmont	SC	$.36
10/15/23	Peachtree RD	Atlanta	GA	$.25
10/12/23	Fair Play	Fair Play	SC	$.34
9/2/23	Mt. Airy	Mt. Airy	NC	$.35
9/1/23	Convention Center	Charleston	WV	$.38

8/31/23	Merrillvile	Merrillvile	IN	$.39
7/28/23	Madison (site unknown)	Madison	WI	$.75
7/4/23	Whitney Way	Madison	WI	$.48 and $.78

It might help to include time of day - many sites have different prices based on time of day either due to local electrical rates or customer load.

This is also something that would be great in a multi-user spreadsheet or preferably an actual database platform as a website. But here in this thread is a great place to start

The main problem here is maintaining the data. Prices at SCs changes over time, so who is going to keep it up to date?

The Tesla app shows SC prices as does the car. ABRP also has them. So, I'm not sure what justification there is for someone to dedicate their time to updating some other data source.

Not sure where to find the rates in the app. I just did a pretend long distance trip that listed about 8 different superchargers and no rates were listed. I would love to put this in a spreadsheet but don't know how to post that here. Any ideas are welcome. There is one duplicate in that one site charged two different rates on different days. I added a time column, but the charging history stats don't include the time. If I post in the future, I will try to remember the time. This is a rough draft, work in progress. Any improvements are most welcome.

If you tap on the Location selection in the app, you can browse nearby chargers (or pan/zoom the map for not so near chargers). When you select one, the app gives you the cost structure for that charger.

BTW, I got curious when I saw Madison, WI listed at 0.75/kWh in your table. This is misleading, as Wisconsin SCs appear to charge on a per minute basis, depending on the charging power. Some states have regulation to the effect that only electric utilities can sell electricity. So, Tesla charges a charging service fee (or similar legal dodge) and charges on a time basis to use the charger. And, since your data is many months old, the current rates appear to have changed, according to Tesla's app. So, you already have a data maintenance problem.

I hate to be a downer, but you are not the first person to try this, and it is more or less a futile effort.

Here is an effort that was started about 18 months ago, and as you can see, has very little data.

https://docs.google.com/spreadsheets/d/1QbM9XG3xTIYBjHfBAk1OTLSZKXZ7jdIV-nZv-2hsbJk/edit?usp=sharing

Not only that, but with frequent changes to prices, it quickly becomes out of date and you can't trust the data anyway.

I believe there was also an attempt, using a CAN bus scanner (or something like that) that would download nearby Supercharger data from the vehicle in the background, with the theory that if there were enough participants in this project you could get a fairly complete pricing map, but AFAIK it didn't go far.

This effort:

died a fairly quick death it appears.

Here is another thread on TMC that describes some older efforts to compile such a price list/map: Supercharger Pricing Map?

On the bright side, the OCPI (Open Charge Point Interface -- basically an API for accessing data about charging stations) does define pricing models in its interface, so there is hope that as the industry matures and becomes more open, we may eventually be able to scrape this. But for now, I just don't think this is a worthwhile endeavor. Until we get pricing data directly from the source, derived tables & maps are going to always be incomplete and out of date. And with variable/tiered pricing, I'm somewhat at a loss as to how useful this information is anyway.
