I have owned a Tesla Model S in the past, so I am experienced with EV charging and the adapters. I had the Tesla wall connector unit in my previous house back when I owned a Model S, but we have since moved and I left it behind.
In our new house, I decided to install a new Gen 3 Tesla Wall Connector just today, to use with my BMW X5 45e. Why you might ask? Because I will probably have another Tesla in the future, likely a Model Y in about a year when another car we have completes it's lease.
Here are my reasons for installing the Tesla charging unit in my garage:
1) The Tesla gen 3 wall unit is only $500 which is cheaper than all of the others on the market.
2) It goes up to 240 volts - 48 amps. Even though the X5 45e cannot use that much, other cars can. I think the X5 45e will only use a maximum of 240 volts - 16 amps.
3) There is an adapter that lets any J-1772 EVs use the Tesla charging units. I planned to buy that adapter regardless so that I can use the Tesla charging units that are so common in luxury resort hotels around Florida.
4) I already have Tesla solar panels 16.4 kW and two Tesla Powerwall2 units (27 kWh of storage) in my garage. I read that Tesla is configuring all of these items to work together in their app, so it made sense to continue with the Tesla charging equipment to complete the system. Everything is Wifi enabled.
So you might ask, why didn't I just get a Tesla car like a Model X or a Model Y? Tesla has used up all of their $7,500 tax credits. BMW has not. The 2021 BMW X5 45e is a killer vehicle. I negotiated an 8% discount off of MSRP and I also get the $7,500 tax credit for this year. The Tesla Model X costs over $90,000+ to get one that has a decent amount of options. So the X5 is just way more cost affordable. With the amount that I drive in my commute, I will likely be in EV mode 95% of the time. Only long range trips will require any gas usage.
Edit: a 115 v - 10 amp outlet probably won't be enough for an overnight recharge of the X5 45e if it is empty.
That will only provide about 1 kWh per hour. The battery pack is 24 kWh in size, but I think only 20-21 kWh is usable for recharging purposes. I saw one article that said only 17 kWh is usable. I don't know what is accurate for sure. But regardless, it will likely take 17-20 hours to recharge from empty using a regular wall outlet. You need to try to get something installed that is at least 220-240 volts and 16 amps.

PERFECT ANWER. Thank you so much. I do have second EV in near future and your set up makes sense to me as well. My x5 went to production as well so hopefully it will be delivered in several weeks.
If you can point me to the adapter we can use with tesla charger I would appreciate that too!
