  1. Raining day yesterday, so I thought I would show my home charging setup.

    Sorry, somehow I'm not seeing the YouTube comments:
    • My understanding is the Tesla distribution connector on the portable 'UMC' is shaped differently than the J1772. Perhaps you might add some details and a compare and contrast?
    • Do you have a 'distribution connector' to J1772 adapter or the state of that technology?
    • Do you have any CHAdeMO to Tesla adapter experience?

  4. The Tesla plug is much smaller and "elegant" compared to the J1772 (not to mention the large CCS and CHAdeMO plugs). Here is a picture of the major plugs:


    All Teslas come with the J1772 adapter. I have used it multiple times on public EVSEs and it works fine.

    Currently the CHAdeMO to tesla adapter does not work with the Model 3. I don't have one, but people have tried.

    I used this last night on my TM3 with the included adaptor and managed to charge just as fast as the mobile tesla charger that went with the car. SmartSelect_20180830-095710_Amazon%20Shopping.jpeg

    What model?

    What is the outlet it is plugged in? A photo would work best.

    Good enough:
    • 32A = 80% * 40A :: Maximum charge current
    • 7.7kW ~= 240V * 32A :: Maximum charge rate
    Were you plugging the Tesla portable EVSE into a 240V outlet? If so, it is very likely they are both charge at 32A although this source claims 40A.

    Are the initial charging rates at miles/hour the same or a little off? The ratio 32/40 would be the expected offset if full current of 32A, Simens, and 40A, Tesla portable, were used from the same outlet.

    What are the circuit breaker(s) for this outlet rated at? If 40A, the safe current would be 32A. Just I don't have a Tesla portable EVSE to check its operation.

    BTW, reading pp. 115 of the Model 3 Owner's Manual explains how it can automatically reduce the current if there is evidence the circuit is about to be over loaded. Other than reading out the kW/hr or miles/hr, can be reduced to avoid tripping the circuit breaker.

    I believe they are backordered 4 weeks.

  16. CHAdeMO adapter now works for the Model 3. I did a test charge:
