Abstract

The purpose of the present invention is to provide a battery module, wherein leakage of a cooling medium is eliminated and the size thereof is reduced, while having the increased number of unit batteries by means of a plurality of battery blocks. A battery module (14) of the present invention has a plurality of battery blocks (1), each of which has a plurality of unit batteries (2) aligned with and connected to each other. The battery module (14) is characterized in having: a cooling plate (12), which is bonded to the unit batteries (1) such that heat can be transferred therebetween; and a cooling pipe (18), which is removably attached to the cooling plate (12), and which is endlessly continuous between at least two battery blocks (1) among the battery blocks (1).

Description

technical field [0001] The invention relates to a battery module with a plurality of battery blocks, each battery block is formed by arranging and connecting a plurality of battery cells. Background technique [0002] In a recent vehicle battery module including a battery block in which a plurality of single cells are arranged, the charging and discharging current is extremely large, and thus generates a large amount of heat. The temperature rise of the single cell reduces the performance and life of the single cell, so cooling is required. [0003] As a method of cooling unit cells, a method of arranging a cooling plate having a refrigerant flow path and a plurality of unit cells in a thermally bonded state, and cooling the unit cells by supplying refrigerant to the cooling plate (for example, Patent No. Literature 1). [0004] Patent Document 1: Japanese Unexamined Patent Publication No. 2010-277863 Contents of the invention [0005] The problem to be solved by the in...
