While TexasEV is correct, you're not going to do immediate harm to the car by leaving it unplugged for a week at a time. The battery management system in the car maintains the battery pack's temperature by heating and cooling it. This uses electricity. If the car is plugged in while it's sitting in your hot garage, the thermal management will use electricity from your utility company to cool the pack. If it isn't plugged in, the power will come from the battery pack itself. This means you're cycling power through the battery pack more often than necessary, leading to degradation sooner than necessary. The point is that you can protect the longevity of the battery pack by leaving the car plugged in as often as possible. That said, I wouldn't worry about it unless you're leaving the car in a really hot or cold location week after week. It doesn't get hot in Atlanta, right?
To answer your question though, you
can use your Bosch charging station with your Model X. The car comes with a J1772-to-Tesla adapter. Attach that to the end of the J1772 pistol thing on the Bosch charging cable and plug that into the Model X. It's a little clunky, but not as bad as it sounds. Just be careful not to drop the adapter. It's heavy and mostly plastic and can crack when it hits concrete. Replacement cost is about $100. Using this keeps you from having to do any additional electrical work to your house, but charging will take longer since the Bosch unit is likely only 24 amps on a 30 amp circuit. The charge cable that comes with the Model X supports up to 40 amps, so if you have a dedicated 50 amp circuit run to your garage and you use the Tesla cable that comes with the car, you can charge the Model X in about half the time that it takes using the Bosch unit.
