2nd Generation Volt to be Supercharger Capable?

Wouldn't it be great if GM partnered with Tesla to expand the use of Supercharger technology? Imagine charging in a few minutes using Superchargers with the next generation Chevrolet Volt that has a larger battery.

GM could use the Tesla Motors adapter too, and make a converter available for those with J1772 EVSEs at home like one of the ClipperCreek models.

There are really only two standards: CCS and CHAdeMO. Tesla uses the same signaling protocol as CCS. Just a different plug. So it would be easy to have an adapter. CHAdeMO is a different story. It's a totally different beast. It's also proprietary.

If Tesla owns the chargers I don't see why it shouldn't be allowed to extend charging privileges or not as it sees fit. Other than the usual hype, the only thing "super" about the Tesla chargers is the battery storage. It's a very slick and innovative solution.

From experience I'd say that "DC Fast Charging" is an oxymoron. Even with the regulatory limit a gas pump would take less than 30 seconds to deliver more energy than any EV battery can hold. Maybe it should be called "DC Faster Charging"?

Supercharging can't be good for the battery.
That was an idea but we haven't seen any evidence of this. Seems like the danger was overblown.
Careful. Tesla is using CCS signaling for A/C charging, and it switches to DCFC with the same 5% pilot signal. But once it switches it talks with CANBus signaling instead of the Homeplug greenphy that a CCS station would use.
That's not what I've understood. Here is a Q&A with Straubel:

Q: What about the communication protocol of the Combo Connector? It’s considered essential for V2G.

A: That’s fine. We’re definitely commonizing with all of that. The only thing that’s up for debate in all of these standards is the physical geometries of the pins and sockets. Everything else is pretty easy to adapt to. The communication standards are pretty universal. We’re 100% compliant with all the J1772 communication levels, signaling, voltage, everything. (emphasis supplied).

I think both CCS and CHAdeMO will handle 100 kW.
