Document Type and Number:
WIPO Patent Application WO/2016/021286
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a high-voltage battery pack with an integrated heat exchanger, allowing both the assembly pre-process and the assembly process to be simplified and shortened by reducing the number of components, and a production method therefor. This battery pack (10) comprises a plurality of battery power generation elements (20), a battery case (30), a lid plate (40), and a heat exchanger (46). Each of the battery power generation elements (20) is a layered body constituted from positive and negative strip-shaped electrodes, the terminal portion of each of the electrodes being exposed directly. The battery case (30) has, on the upper surface (30a) thereof, first to fourth battery power generation element housing portions (32a to 32d) formed with spacing therebetween, each having a recessed portion. Each of the battery power generation elements (20) is housed in each of the recessed portions. In addition, first to third bus bars for electrically connecting the terminal portions of the directly exposed electrodes are fitted into first to third bus bar housing portions (36a to 36c) of the battery case (30). The lid plate (40) is provided with sealing members (44) for liquid-tight sealing of each battery power generation element (20). The heat exchanger (46) is embedded inside the lid plate (40).
