Abstract

The present invention provides a battery module capable of arranging a sensor device on the upper surface of a battery cell laminate and suppressing a height dimension. The battery module 1 includes:a cell-stacked body 2 constituted by stacking a plurality of cells 21; and a sensor device 7 configured to detect a voltage of each cell 21s. The sensor device 7 is disposed on an upper portion of thecell-stacked body 2. The sensor device 7 is provided with a sensor bulging portion 731a which bulges downward, and the upper portion of the cell-stacked body 2 is provided with a low-height portion 243 accommodating the sensor bulging portion 731a.

Description

technical field [0001] The present invention relates to a battery module mounted on an electric vehicle or the like. Background technique [0002] Conventionally, battery modules are mounted on electric vehicles and the like. For example, Patent Document 1 discloses a battery module including a battery cell stack constituted by stacking a plurality of battery cells, and a sensor device that detects the voltage of each battery cell. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Laid-Open No. 2016-072181 [0005] However, in the battery module disclosed in Patent Document 1, the sensor device is disposed on the upper surface of the battery cell stack, and therefore the height of the battery module may increase significantly. Contents of the invention [0006] The present invention provides a battery module in which a sensor device is arranged on the upper surface of a battery cell stack and the height dimension can be suppressed. [0007] The ...
