Battery module

Abstract

The present disclosure relates to a battery module. The battery module includes a plurality of battery units connected in series; an electrode output connecting piece disposed at an output end of the plurality of battery units; a plurality of bridging busbars, each connecting two battery units spaced by another battery unit or more battery units among the plurality of battery units; and an adjacent busbar connecting adjacent battery units among the plurality of battery units. An electrical connection path is formed in the battery module by the electrode output connecting piece, the bridging busbars and the adjacent busbar. At least two of the plurality of bridging busbars partially overlap and fit one another in an electrical insulation manner as a group. The battery module according to the present disclosure is applicable in diverse situations, and capable of improving safety performance and energy density.
