We just took delivery of our X75 in addition to my S90D - family's transition to zero emission vehicle is now complete.
To charge both I've installed 2 PWC on the same line on a 60A breaker with the sharing function. My expectation was that when both cars are charging current will be split, so 24A each. To my surprise it doesn't really work that way: the system is dynamically balancing current so both cars will finish charging at the same time. For example my S SOC was significantly lower than the X, so it received in that case 28A while letting the X having the remaining 20A, and through the App I could see both would take the same time to reach their programmed 90%.
To test this I set the SOC target of the S to 100% and it started soon after to increase current to 30A for the S and 18 for the X. I think it is a neat feature (that I was not expecting, did not see that in the manual or description).
Now out of curiosity I'd like to know who's doing the control, ie car to car communication through the PWC or directly the master PWC?
And for you out there with more than a PWC did you notice the same behavior?
