P90D Supercharging Data

So around midnight I charged the car to 90%, went on a drive to get it down to 8% and then recorded all the data while doing a range charge at a supercharger. I had provided some of this before via photos, but there was another request to do <10% to >90%

Here's the link to the graphs. I could post pictures, but with these graphs you can zoom in on sections by clicking and dragging the timeline you want.

I hope this is useful.

P.S. the max battery option was never on. Just a long, calm drive.

Edit: A/C was off, music was on, no sharing of power feeds.

"You must spread some reputation around before giving it to Pete90d again"

This is great data, looks like P90D owners will have a slight advantage when charging to more than about 235mi range, otherwise things are about equal.

Thanks a lot! Very useful!
Q: how did you collect the data? And I love how the graphs are interactive. How is that done?

I wrote some code that made use of the REST API and then just tethered my laptop to my phone and polled the API continuously.

Highcharts has great graphing libraries, they do all the heavy lifting. I just tell it how I want it to look and give it the data.

Thanks for doing this. Unfortunately this data is very difficult for me to interpret. I would need to see power (kW) v SOC in order to compare with your previous data posted.

It's updated.

Something is very very wrong. The ways it's posted now kW power increases with SOC. This should be the opposite.

---updated---

Back on my desktop now so I can take a closer look. Seems like at 40% you were get 84 kW (based on V x A). This is about 10-15 kW lower than what I've seen 85 kwh packs get. The mystery continues.

I thought you wanted the kW that was added as the SoC increased.

Here are the options. Tell me what combinations you want

time_to_full_charge (hrs)
battery_range (mi)
charger_power (A?)
battery_current (A)
battery_level (SoC)
charge_energy_added (kW)
charge_rate (Wh/mi)
charger_voltage (V)
charge_miles_added_rated (mi)

Could you post the raw data? Extra credit if it is in Excel or similar format.
Thank you for doing this... I'm very interested in figuring out how fast my future 90D is going to charge...

Here is Supercharger power vs. time for first 6 minutes... (I'm entering data by hand, so it is slow going...)
You are charging at 115 kW for about the first 4 minutes and averaging about 100 kW for the next 2 minutes.

Yes, I second that. If you have time vs SOC data in tabular format, can you upload an excel file or create a google sheets file. Google sheets would be better I think.

Pete, in the opening message you could use the term supercharging instead charging. It is not clear this is about supercharging. In this forum messages can be edited for 24 hours. Maybe the title should be updated too but only moderators can change that.
