We picked up our X 100D last week and have been charging it using the same Tesla 14-50 connector (on a 50A circuit) that we were using with our 2012 S P85. We've noticed the X 100D will start at 40A and then reduce the amps to 26 or 27 by the end of charging. Has anyone else seen this? Has Tesla changed the charging algorithm to introduce tapering for home charging? Is there an incompatibility between the 14-50 connector and the new cars? Or could we have a problem with the onboard charging hardware?
