Does Chargepoint even have a unit that goes more than 40a?
I think it's fine. And yes, I do think you should just future proof things if you're gonna install a Level 2. I put in a 2nd Level 2 for the 45e. I have a Model 3. 40a charging is fine.
The onboard charger that BMW put in the 45e (3.something kW) is just idiotic though. I know someone likes to argue that most homes in the US only have 110v plugs. I also argue that's irrelevant. Those homes also have 220 for things like dryers. Either way, if you buy an electric vehicle, you're gonna want a Level 2 anyways. Even if you don't own the home, BMW still should have put in a higher charger in the car so it can use Level 2 public chargers. As it is now, someone with a 45e can't use a public charger b/c it's cost prohibitive due to the slow charge rate.
