The best quick charging experience at INOITY 380kW charging station [INONITY-Himmelkron](https://www.goingelectric.de/stromtankstellen/Deutschland/Himmelkron/IONITY-Euro-Rastpark-Bayreuther-Strasse-1-3/33229/) with a short interruption ![Figure_18](https://user-images.githubusercontent.com/5459845/62480612-96953a00-b7b0-11e9-929d-41f62e845dd7.png) [INONITY-Hohenwarsleben](https://www.goingelectric.de/stromtankstellen/Deutschland/Hohenwarsleben/IONITY-Euro-Rastpark-Zum-Raukler-1/33434/) ![Figure_32](https://user-images.githubusercontent.com/5459845/62480624-9d23b180-b7b0-11e9-993d-37ff66a52996.png) [INONITY-Lippetal](https://www.goingelectric.de/stromtankstellen/Deutschland/Lippetal/IONITY-Euro-Rastpark-Straengenbach-1/37655/) ![Figure_33](https://user-images.githubusercontent.com/5459845/62480630-a1e86580-b7b0-11e9-94f9-36f4a2a4d321.png)

And a typical charging at my home with Mennekes 22kW here only max 7.2kW ![Figure_34](https://user-images.githubusercontent.com/5459845/62480985-86318f00-b7b1-11e9-87a5-266529bf7625.png)

Added GPS logging, did some more bug fixing, and a bit more robustness. A sample time series is also included. Still this is very much happy path engineering... Ready for...

While empirical scanning through the data I found the battery energy in kWh ;-) ``` EV_RANGE_VSC_INITIAL_HV_BATT_ENERGYx100 EV_RANGE_VSC_REVISED_HV_BATT_ENERGYx100 ``` Which correlates nicely with `EV_STATE_OF_CHARGE` as you can see in the attached...

Now there is only one more mystery left: How to calculate the real charging power in kW from `EV_CHARGING_RATE_SOC_PER_HOUR` in %.

I can only guess the difference between `INITAL` and `REVISED`. Maybe it is model the ageing of the battery? If you look at the chart above there is hardly a...

Do you want me to do a formal correlation analysis for `EV_STATE_OF_CHARGE` and `EV_RANGE_VSC_INITIAL_HV_BATT_ENERGYx100`. Shouldn't be that difficult with python...

SaaS = Statistics-as-a-Service ;-) ``` print(timeseries['EV_STATE_OF_CHARGE'].corr(timeseries['EV_RANGE_VSC_INITIAL_HV_BATT_ENERGYx100'])) print(timeseries['EV_STATE_OF_CHARGE'].corr(timeseries['EV_RANGE_VSC_REVISED_HV_BATT_ENERGYx100'])) print(timeseries['EV_RANGE_VSC_INITIAL_HV_BATT_ENERGYx100'].corr(timeseries['EV_RANGE_VSC_REVISED_HV_BATT_ENERGYx100'])) ``` results in ``` 0.9955738575736692 0.995446940831017 0.9999284070411001 ``` no doubt - the data is highly correlated

... which leads to the idea of a correlation map like this https://medium.com/@sebastiannorena/finding-correlation-between-many-variables-multidimensional-dataset-with-python-5deb3f39ffb3 ... next week. Will be in the mountains the next 3 days ;-)

Correlation map is ready. Needs you and other eyes to gather insights ![Figure_correlation1](https://user-images.githubusercontent.com/5459845/62832089-7985be80-bc29-11e9-9101-ba4eeacf1037.png) White spots are due to "NaN" correlation. This datasets have Zero variance and therefore correlation is not...
