    Which is a common thing. On the web side here, I often see developers who put out something functional, with no care given to usability.

    Here are the specs. DC Level 2 is rated up to 100 kW which on the surface seems to cover the SuperCharger rating of 90 kW, but they've also listed max current of 200A. The SuperCharger is estimated to be 360V @ 250A, which is above the DC L2 spec.

    Also interesting that they estimate the 20 min charge time with a 25kWh pack (20% to 80%). Who is going to do a road trip in a BEV with a 25kWh pack?

    CHAdeMO is improving...

    I wouldn't even give it a "10" for Functionality. J1772 doesn't appear to support 3-phase charging, which is a real short-fall for much of Europe. Or am I missing something?

    Well you're missing that they'll use the type-2 version of the connector in Europe. Type-1 and type-2 versions of the combo connector are agreed to have the safe communication protocols and the same envelope so that manufacturers can put in the region appropriate connector.

    In fairness this is really what the Tesla Supercharger plug looks like:

    Agreed, from a mechanical standpoint, using the gun grip shape will cause people to use it like a petrol station and will pull away with force on the handle which will most likely end up causing fit issues and eventually cause the plug/connection to wear out quickly (I'm guessing stronger individuals will crack/break either the male or female end)

    I much prefer TM's straight handle so as to allow the force to be straight out of the plug. The fit from cinergi's videos really show how tight it is currently and so I'm guessing having a pair of leather driving gloves is going to serve yet another purpose in an EV.
