The capability is itself a technology or a kind of physical system, and the classification names it. Battery cells themselves (H01M) are left to Critical Technology; gas distribution pipelines sit in F17D under Resource Infrastructure. B60L53/00 includes on-board chargers. The crosswalk is a first pass that nobody has reviewed.
