I had a second charger installed in my S 85D in October, and since then I've tried to charge at a few HPWCs that I believe were able to deliver more than 40 amps (one station was 72 amps, one was 80 amps), but in all cases the car only took 40 amps. When plugged into one of these HPWCs, the max rate is shown as expected, and the current setting on the charging panel matches that max rate. But the charge current never goes above 40 amps. This could be an installation problem that I need to get fixed at the service center, but I wanted to see whether anyone else experienced this after having a second charger installed. Or maybe there is something I am not doing right?
