I have just purchased a Taycan 4S. I had installed a 240 outlet installed in my garage, and I have completed the settings on the Porsche charging unit. The unit is set to charge at its fastest speed. When I plugged in the car this evening, the charging unit indicated the battery was charged to 51%. The charging unit indicated that it would take 15 hours and 15 minutes to complete the battery recharge. I am surprised at the length of time it will take to charge from 51% to full charge. Am I missing something?
