This strikes me as a direct consequence of galvanic isolation provided by isolation link stage in prevailing architectures, something the article proposes to eliminate.

I'm struggling to imagine how a magnitude of surge energy sufficient to "melt the conductors in the charging cable" while directly coupled to a charger and without galvanic isolation leaves an EV's battery unscathed in such an event. What exactly isolates/protects the battery again?
