Replace that charge station pro with a 100 Amp sub panel, and throw in two Tesla or other chargers, should be all set.With two EVs it is not hard to imagine that eventually you will want them both plugged in at the same time. Using the Tesla wall connector will allow you to add a second one for the second vehicle, Tesla or not, without having to upgrade your wiring. End up with a third? Just add another wall unit. Being sure to go with a model that allows load sharing will future-proof your garage.
