Not that I am aware of...
People talk about the Bolt not being able to handle what the Superchargers put out, but that isn't totally accurate.
The Superchargers can and do put out lower amounts as the Tesla's get closer to full.
The Model 3 takes less than the Model S, etc..
It would be the same with the Bolt, if an adapter were made.
Either the adapter (it would have to be it's own computer) and/or the Supercharger would negotiate the "safe rate" for charging.
It would be slower than the current Teslas (and even slower than a Model 3 likely), but still do-able.
Basically, the adapter would tell the Supercharger what the safe rates are, and on the other end, it would pretend to the Bolt that it is a CCS charger.
What I am not sure about tho, is whether it could be faster than what the CCS does now with the Bolt. I don't think so..
I believe the Bolt is limited currently to lower than what the pack could probably take safely now, and if that is an "in the car" limitation, I'm not sure the adapter would be able to send more..
That might require a firmware update on the Bolt.
I think it would be the same with a faster CCS unit. I think the limit is currently set in the Bolt...
With all that being said, I don't expect any of it to happen.
I know Musk has said he'd be willing to do it in theory, but I don't see it happening.
Love to be wrong about that tho..
