You guys have any reservation when it comes to that equipment?
A BMW branded EVSE doesn't mean anything to me. I'd be surprised if BMW actually made it. From what I can tell it's a 30 amp EVSE (maybe 32). Original cost is around $1270, so 30% would be around $380. I guess the question is what would a JB or CC 30 amp unit cost? And is a 30 amp charger what you really want, especially since there's a Tesla (larger battery) in your future ? Personally, I wouldn't go less than 40 amps and I would go higher if I could.
I checked JB and CC website. Their 32 amp EVSE's are ~$480, or about $100 more than the used BMW wall pure. So, if you're satisfied with a 32 amp charger go with the BMW unit.
As one data point, I have a '17 i3 with the 33Kw battery(94 Ah). The charger on the car is limited to 7.2 KW (~32 amps at 240V). It takes about 5 hours to fully charge. A car with, say, a 60KW battery would take almost twice that time, all other things being equal. I don't know what the Tesla charger is limited to, but if it's 7.2KW, then the 32 amp BMW unit would be ok. If it's more than 7.2, you might consider sizing your EVSE to match the Tesla's limitation.
