Looks like Phoenix Contact will be the company that is building the charging system for Taycan. https://www.phoenixcontact.com/onli...ormation/078b4f66-2e30-4b1e-ae8d-38ed8ccfb1cf Based on the video of driving in the winter, this is the manufacturer. If you browse the website you can see how they say they attain the high speed charge using a liquid cooled charger. https://www.phoenixcontact.com/onli...ity_P-29/915a6b27-2307-48e1-a398-ecd45f5bfd1a It's a privately held German company. I don't know if this has been posted elsewhere, sorry if it has.
