The charger is connected to the mains electrical grid. The specification of the mains grid is what determines the total wattage that is available at any one time. Watts = Volts × Current. Watts can not be changed. If you know the voltage and current limitations of the mains grid, you know the hard limit on the watts supplied based on the limitations of the grid to your home. The only way to alter this equation is adding local storage.
An above average home is only capable of 240V/100A=24kW. This is due to the wire sizes used, and transformer at the pole, along with local grid infrastructure that connects them. Use this 24kW to help understand the scales involved too. Supplying 240kW safely, in the real world, without marketing idiots would require at least ten times the infrastructure that supplies your entire home. This could be done with a massive local battery, but it is not going to be cheap, small, or or simple. I can only speculate here, but the build specification is likely limited by temperature due to high current flow. The components capable of dealing with temperature tend to have higher power ratings. Marketing criminals tend to take these numbers and run with them when they are completely irrelevant to the real design constraints.
These aren’t designed for homes. Three phase power exists in the US for commercial customers that set up fast chargers. I grew up in Europe and we had three phase power for our residential AC as well.
