because it's always good to have options Example: a few weeks back the entire Albuquerque Supercharger was down. Having an EA handy as backup would be useful. I use ChargePoints at work a lot. Always good to have options.
at the Tesla club event I was at yesterday, one of the Tesla Mobile techs that was there had pulled a CHAdeMo adaptor out of his work car (to get to something else) and someone asked him if he has heard anything on when it will be usable on the 3. He first said "we don't hear anything before you all hear about it", then said about once a week, when he is nearby a CHAdeMo station and with a 3 he asks the owner if they can go try it out (including having just done this friday). so far, no luck, but his is persistent!
others in the conversation suggested that when the Model 3 starts being delivered to Japan, is when we will see it ready to use CHAdeMo. (I think the person that said that was another Tesla service employee).
With any good luck CCS is in the pipeline. . It's a big shame Tesla didn't do this for the US cars. From Tesla's web site - the SC's overseas will be retrofitted with a second cable. https://www.tesla.com/de_CH/support/model-3-charging. Translated to:
Does the Model 3 also get access to the Supercharger network in Europe?
Yes. We will be upgrading existing Super Charger charging stations with dual charging cables that are compatible with CCS Combo 2 (CCS) and DC Type 2 charging port types.
Does the Model 3 get access to the "Destination Charging" network in Europe for partner store shopping?
Yes. The Model 3 can be charged at any "Type 2" AC Charging Station, including the Tesla Wall Charger, at Destination Charging destination locations.
With the plug being in the cars overseas and SC's being updated with CCS cables they have the engineering already done for the 3 with CCS and the SC. Just doesn't make sense we won't get CCS in some manner. Electrify America chargers are coming. If Tesla's don't use them, they won't get much use for some amount of time, just aren't that many other EV's on the road.
