Hi, and apologies if this question has been asked.
I have a M3 Long Range that I charge using a Tesla Wall Connector on a 60-amp (breaker) 240V circuit. My wife recently bought a BMW plug-in hybrid (off topic: I wanted her to buy a Model Y, for her reasons see “PS” below) and so I want to install a second charger.
I’m told that two Tesla Wall Connectors can be connected to a single 60A circuit and networked together so that the two cars charging at the same time will never exceed the maximum current draw — but otherwise both cars can use whatever amperage is available, without limiting charge rate when only one car is charging. This is appealing to me because adding additional amps might require an expensive upgrade to my home electricity service. I also don’t want to permanently reduce the charge rate of my M3 (except obviously on those occasions when we are both charging at the same time.)
My question is: if I install a second Wall Connector and buy a Tesla->J1772 adapter for her car, will the shared current limits still work properly? Or does this only work when two Teslas are plugged in? Alternatively is there a cheaper/simpler option that wouldn’t require any circuit upgrades to that 60A circuit, yet would still allow me to charge my M3 at full rate when she’s not charging? (I know the Tesla connector is a luxury compared to third party units but I’m also hoping we can replace the BMW someday, so I’m willing to spend the money on hope.)
PS To explain the “why” above: I convinced my wife to test drive the Model Y, and at first it was promising: she said it was the most comfortable car she ever sat in. Then she tried driving it and hated the one-pedal regenerative breaking — to the point where she couldn’t even finish the test drive. I told her no problem, you can reduce the aggressiveness of the regen with a setting. However, the lower regen setting has been removed on all newer Teslas! The result is that the MY was out and she insisted on buying this stupid BMW hybrid with its negligible electric range. I’m annoyed that Tesla removed the simple option. It certainly cost them this sale.
