...As far as options I think we'd probably see the 10kW onboard charger. There's the cost savings of keeping the same part as well as the extra sales of the HPWC. Since there are any number of cheaper J1772 that will do 7kW or very close to it there's not nearly as many that can give a 10kW charger it's full power. This doesn't only apply for the home market but also the business/work market. The at work market also might multiply sales. Say for example the first EV driver at your work gets them to install a Tesla HPWC and then you look at an EV. If you want to charge at work you're only choice (unless you know about the pending adapter out) is to also buy a Tesla.
Since I'm planning to switch to the Model 3 in a few years, assuming it comes close on planned price and specs, I've been looking into Tesla charging. What immediately became clear is that you don't need a J1772 EVSE
at all because the
"Mobile Connector" that comes with the car just plugs-in to a standard 14-50 outlet (or 10-30 outlet, if 30 amps is all that's practical). That's good for me because my current 2012 model EVSE Upgrade won't work with Teslas. But it is downright trivial for me to switch out the L6-20 outlet and breaker for a 14-50 outlet and breaker (with increased wire size, of course).
I don't really get the attraction of HPWC for home use. 9.6 kW isn't enough? Why? How many people are going to drain the car everyday and need to turn around and use it again in a few hours? Those seem like edge cases to me; surely the vast majority of people don't need very fast charging
at home (or work). For destination charging at hotels and the like, sure. Otherwise I just don't get it.
In addition, since the range of a Tesla is 200+ miles, there is no reason to carry the portable EVSE for local driving. That means that unplugging it from the wall and taking it on the occasional road trip isn't much of a hassle. And if the portable EVSE is needed in the car regularly, you can buy a second one quite easily.
