Two Reasons It's a Bad Idea for GM to use Tesla Superchargers

The Chevy Bolt is a smaller car with presumably a smaller battery. Pumping that current is not a good idea; Tesla gets away with because of battery size. Sure the Bolt could be designed to throttle back the charge, but then you lose some advantage to the quick charge.

Second issue is battery chemistry. Not all lithium batteries are created equal and they. Tesla uses NCA. The Bolt, if the whispers are to be believed, is supposed to use NCM.
From what I've read NCM degrades faster than NCA.
