OK, I'll add my data point for my 2018 LR RWD. This past July during a road trip, three months after my battery warranty expired, I plugged into a greater than 24amp EVSE for the first time in over a year. Tried to charge at 48amps, but soon threw the dreaded PCS_a019 error and it backed down to 32amps @200VAC (why the voltage drop from 240VAC ???).
Residential electricity is generally split phase. There is one neutral and two hot wires, and each hot wire is 120V with respect to neutral. They are also 180° out of phase with each other, i.e. when the voltage of one is +X, the voltage of the other is -X. This makes 240V from hot to hot. Commercial electricity is 3 phase instead of split phase. There is a neutral and not two but
three separate hot lines. Each hot line is 120V with respect to neutral, but is out of phase 120° with respect to the others. Like this:
Some motors can use all 3 phases and there is a big advantage to using 3 phase if you are running a motor. You can also deliver more power over the same amount of conducting material on a 3 phase system (with 4 wires, the 3 hots plus a neutral) than you can over a split phase system. Tesla's OBCs in some countries actually can use all 3 phases, and the J3068 (Mennekes) connector supplies all 3 phases to a vehicle. But in North America, the J1772 connector and Tesla Proprietary Connector only supply 2 AC lines to the OBC. But if you're on a 3 phase system in a commercial building, which two do you use? And the answer is you take two of the 3 phases (either 1+2, 2+3, or 1+3) and use them to power the OBC. What's the voltage from phase to phase? Well unlike in split phase, where it's twice the phase to neutral voltage, it's the phase to neutral voltage multiplied by the square root of 3. 120*sqrt(3) V = 207.8V. This is commonly referred to as 208Y/120V power. By the way, the entire electricity grid from generators to transmission transformers to power substations is 3 phase. It is only at the last step, where power is converted to 240V split phase for residential usage, that one of the 3 phases is dropped.
By the way, some large apartment buildings and condo complexes have a system where they have a 3 phase transformer supplying the building, but each unit only has 2 of the 3 phases. In other words, the electrical panels are like any other residential panel, with 2 hot wires and one neutral, but if you measure the voltage from hot to hot, you'll measure around 208V. And if you connect an oscilloscope to the two hot wires and put the ground probe on neutral, you'll see a graph like the one above, but with one of the 3 phases missing. In such a scenario, your next door neighbor might have one of the phases that is missing from your panel, and you'd have one that is missing from his or her panel. If you look at the name plates for major appliances like ovens, dryers, stoves, AC units, etc., they'll generally show that they're designed to run on anything between 208V and 240V. This is why.
