BATTERY PACK INCLUDING BUS BAR ASSEMBLY FORMED PROTRUSION PORTION FOR INSULATION

摘要

The present invention provides a battery pack capable of preventing a short circuit between an end plate and the electrode terminal of a battery module even if a strong outer force is applied. The battery pack which includes: a battery module assembly in which two or more battery modules where one or two or more battery cells are mounted on a cartridge are arranged on the side to be in contact or close to each other; a pair of a front support member and a rear support member which surround the front side and the rear side of the outermost battery modules of the battery module assembly; insulation sheets each of which is placed between the pair of the front support member and the rear support member and unit modules placed on the outermost side of the battery module assembly; and a bus bar assembly which is mounted on the top of the battery module assembly and electrically connects the battery modules in series or parallel. The bus bar assembly, in order to prevent a short circuit between the front support member or the rear support member and the electrode terminal of the outermost battery modules of the battery module assembly, has an insulation projection unit which is downwardly extended between the front support member or the rear support member and the battery module assembly on the bottom.
