As a successor to our Phaeton, we consider buying a second-hand TaicanCT. Timeless elegance, German value work, which is special, air suspension, four-wheel drive, controllable ground clearance, large trunk, comfort seats, plenty of glass, sufficient power reserves and gigantic price decline for four-year-old luxury – sounds familiar. However, when it comes to smarting, I now stumble over incomprehensible information: According to Wikipedia ALL Taycans have a system voltage of 800 volts. However, I always read only about charging with 400 volts DC. For me that doesn’t fit together. Or is there any hardware and/or software upgrade, because Porsche was at first faster than the charging infrastructure in D and you can now charge 800V. Or can all current fast charging column now 400 and 800 volts DC? Thank you very much.
