Battery Module Having Sensing Assembly and Busbar Assembly

Abstract

Disclosed is a battery module which is easily connected to a plurality of battery cells, a bus bar assembly, and a sensing assembly to improve manufacturability. To this end, the battery module of thepresent invention comprises: a cell stack formed by stacking a plurality of battery cells including at least one of sensing negative and positive electrode leads together with positive and negative electrode leads; and a bus bar assembly including a plurality of connection bus bars electrically connected to any one of the positive and negative electrode leads, a plurality of sensing bus bars electrically connected to the sensing negative and positive electrode leads provided in each of the battery cells, and a plurality of bus bar frames having a connection receiving unit on which the connection bus bars are seated and a sensing receiving unit on which the sensing bus bars are seated; and a sensing assembly including a circuit board electrically connected to the connection bus bars and the sensing bus bars, and a sensing frame mounted on a front surface of the bus bar assembly and having a substrate-embedded unit for receiving the circuit board therein.

Description

technical field [0001] The present disclosure relates to a battery module including a sensing assembly and a bus bar assembly, and more particularly, to a battery module that facilitates electrical connection of a plurality of battery cells to the bus bar assembly and the sensing assembly. With increased productivity. [0002] This application claims priority from Korean Patent Application No. 10-2017-0152984 filed in Korea on November 16, 2017, the disclosure of which is incorporated herein by reference. Background technique [0003] Currently commercially available secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among these batteries, compared with nickel-based secondary batteries, lithium secondary batteries have almost no The advantages of free charge / discharge due to memory effect, very low self-discharge rate, and high energy density have attracted much attention. [0004] Such l...

Problems solved by technology

However, since this type of detection device has a structure that connects the bus bar to the electrode leads of the secondary battery, many wires are required to detect voltage, etc., and therefore, the assembly process of the battery module is complicated and the possibility of defects is increased.
