I have this specific charger since mid-November and I use it almost daily. During the start of charging (battery level below 90%) and if the car starts charging immediately upon arrival home, even if a considerable amount of time has passed since then, the charger provides a power of 22.3-22.8 kW. Now, how can a 22 kW charger exceed the maximum power supply, is a matter to be investigated. If the car is cold, i.e. at least 4 hours have passed since its last use, the start of charging provides a power of 21.4-21.8 kW. Then, until the battery level exceeds 95%, the device provides the aforementioned power for each case. When the battery level exceeds 95%, then and only then, the provided power of the charger drops below 20 kW and gradually approaches 10, from which it drops even lower to 7, after the car reaches 99% of the charging level and remains in it for possibly over an hour many times without actually adding energy to the battery. Now, when it goes somewhere, I cannot know the indicated power on the charger's screen. However, the car's autonomy does not increase further.

The aforementioned behavior was not observed from the first uses of the charger. I remember that in the first uses of the charger, regardless of how many hours had passed since the car's arrival, the starting power was always below 22 kW. When the charging level exceeded 80%, the provided power of the charger dropped in half, i.e. below 11 kW. With a charging level of 90% and above, the power was reduced below 5 kW and I remember approaching full charge, I had seen 3.5 kW. When exactly the behavior of the charger changed and became problematic, I cannot say for sure. I think, however, that it happened after the first 3 months of almost daily use.

Now, with the aforementioned problematic behavior of the charger, if the car starts charging a short time after its use, when the charging level exceeds 90%, the car's inverter almost always activates to cool the battery. This means that with the problematic behavior of the charger, the battery is being stressed, with all that this entails for its lifespan. Additionally, the battery shows that it is being pushed for another reason: when the charge level indication reaches 99%, if I remove the car from charging, after a short time (5-10 minutes), the charge level has dropped to 85-90% and so has the car's autonomy.
