Back to business 
If I were to assume that speed of charging is of paramount importance: which system (Tesla, or the J1772 standard); does it better?
I'm sensing a "VHS versus Betamax" mess...  |
Yeah it is a little VHS/Betamax (very much so since Betamax was Sony and VHS was everyone else).
"Better" is a bit of a quandry: By what metric is better? watching that video you'd think Tesla is better and, at the moment, they are: simple plug in to charge and it works. It is also a more mature system than the DCFC network so yeah..
The "Plug in and Charge" system is just coming online now some chargers support it some don't (and the Mach-E is one of the first vehicles to support it). The idea is similar to Tesla's: You just plug your car in and it starts charging (the car & charger negotiates payment and charge rate automatically).
Again the non-Tesla network has some catching up to do but it will get there.
I think I mentioned rates earlier: I belive max Tesla charge rate (for the latest Model 3's and Y's) is 250kW (fill up a Model 3 from 5% to 90% in 37 minutes).
Electrify America are putting DCFC chargers in that can charge up to 350kW but the car has to support it (Mach-E's max rate is 150kW 10% - 80% in 45 minutes).
