SAE hobbled themselves

    It goes a long way to explaining why Tesla went proprietary:
    • Tesla plug with 120-250 kW fast DC charging capability
    • Tesla plug with up to 19.2 kW AC charging capability (Model S option)
    • Tesla plug is smaller than the hobbled, J1772 (max 80A DC rating)
    • Tesla Supercharging is ~1/3 to 1/4 the cost of CCS-1 and CHAdeMO
    Tesla voted with their SuperChargers in the free market and has all but defeated the CCS-1 camp. SuperChargers overtook CHAdeMO by their 24/7 available, autopay SuperChargers. A powerful sales advantage, Model 3 sales have all but crushed the SAE compliant cars.

    Tesla already sends a J1772-to-Tesla adapter with every Model 3. Given what we've seen in Europe, Tesla has already developed a CCS-2 (Menke) adapter in Europe. It is only a matter of time until Tesla makes a CCS-1 adapter so we can pay 3-4x as much per charge at a convenient EVgo/Electrify America/<tbd> network.

    There will never be a SuperCharger to CCS-1 adapter unless the SAE friendly EV makers finally contribute to the SuperCharger network. In effect, Tesla voted with their money and won. The others have yet to realize they are defeated.
