Assuming this is about the same thing as the other BYD charging article I saw a couple days ago, they're using a higher voltage, which would let them charge faster without needing a thicker* cable.
(* The copper need not be thicker, but the insulation might need to be)
Exactly. More energy means either more copper or more rubber in the cable.
Rubber is cheap though, and flexible. If it's the size of a gas pump hose, oh well; gas pump hoses are also rubber. As long as they don't have to make the copper ridiculously thick, it shouldn't matter how thick the cable overall is
