Question about the Model S charger

[fairlycool]

Hey guys,

I have a question about the charging socket that Tesla is using in the Model S. I've seen that its smaller that the regular charging points (the ubiquitous J1772) that we find around the Bay Area. Will the Model S charge from these stations with J1772 sockets? or does it need a new completely different type of charging station?

The reason I ask is because I live in an apartment and plan on charging my Model S at public charging points.

Thanks!

We were told that J1772 adapters would be available at release.

I heard the J1772 adapter will be a module, not a cable, and it will lock into the car when inserted. So if someone pulls the J1772 cable they can't take the adapter with them.

I believe that Tesla should have a place in the side of the trunk next to the charge port where all of the "adapters" can be permanently located. Much better than a bag of adapters that bounces about the car or trunk (boot for you britts) while driving!

Tesla are saying on the website that the adapters are included:




Nice!

So both ends of the cable need adapters or would the j1772 adapter be on the end opposite the end that plugs into the vehicle? I'm guessing the wall outlet plugs are adapters too? Just trying to picture this, and plan my garage out

Does someone knows, the charger being air- or liquid cooled?

My guess is that the J1772 adapter and home/campground adapters are very different.
J1772 adapter - just a small stub that plugs into the S charge port, and then the J1772 plug goes into the other side just basically sticking out the side of the car a little bit. No extra cable.

For home use up to 9.6kW (240V@40A) one would use the UMC2, which I gather will be included with every Model S, and use an adapter on the end of the plug end right before it goes into the wall (e.g.: dryer outlet, stove outlet, NEMA14-50, etc.)

If you needed faster home charging then an HPC2 could be installed permanently which (I think) would just have a new Tesla plug on the car end and could do up to 19.2kW charging (240V@80A) assuming you ordered the S with the dual charger option, and have a 100A circuit breaker available.

That's a good question. The onboard charger is located under the rear seats. How much power do you expect gets sunk as heat? (What's the anticipated efficiency?) Given the location, it not obvious that there is a path for proper air cooling. Is it not enough to be thermally anchored to that large aluminum chassis? I suppose it would be possible to add the charger on the motor/inverter cooling loop, but I haven't heard anyone say anything that would indicate that was the plan.

I wonder if we will be able to convert the existing HPC's to HPC2's and at least get the 70A that they are able.
