Abstract

A battery module is provided. The battery module includes: a housing accommodating a plurality of battery packs electrically connected to each other; and a high-voltage connector formed on the housing, wherein the high-voltage connector includes: a terminal block including an electrode through which current flows and a shielding portion formed to surround the electrode; a connection block electrically connected to the shielding portion; and a bracket interposed between the terminal block and the connection block, wherein the bracket includes a first ground hole forming an electrical connection with the connection block and a second ground hole forming an electrical connection with the housing, and a helical pattern is formed in the first and second ground holes. Accordingly, electromagnetic noise may be effectively shielded and removed.
