High-voltage battery and motor vehicle

Abstract

High-voltage battery (20) of a motor vehicle, wherein a low-voltage interface (26) (LV interface for low-voltage interface) for communication with the battery management system of the battery cell is arranged on a head plate (22) of a battery module (24) of the high-voltage battery (20), wherein a connection (28) for introducing air or other test gas or for extracting air or other test gas for leak testing is arranged in the LV interface (26), wherein the LV interface (26) with connection (28) for introducing or extracting air has a quick-coupling system header (30) for connecting a test adapter (32) for leak testing, wherein the quick-coupling system header (30) is configured to couple a test adapter (32) by pushing it in or sliding it on, wherein the quick-coupling system header (30) has a base (34),with which it is attached to the head plate (22) or to a CMC cover (36) and wherein a pipe (38) initially projects from the base (34) in a perpendicular direction to the mounting plane, transitioning into a bend (39) to bring the pipe (40) into an angle or into a largely parallel orientation to the mounting plane.
