Problems solved by technology

[0005] However, as shown in Patent Document 1, in the battery module in which the sensor device is arranged on the upper surface of the battery cell stack, the height dimension may be greatly increased.
In particular, in a battery module using a bus bar having an upwardly protruding bent portion in the middle of the stacking direction of the battery cells in order to relieve the stress acting on the battery cells due to expansion, the height dimension may be greatly increased, and with The insertion and removal of the connector connected to the sensor device may also be hindered by the bent part of the bus bar

Abstract

The present invention provides a battery module which can ensure the plugging space of a connector and inhibiting the height size. The battery module includes: a cell-stacked body constituted by stacking a plurality of cells; a plurality of bus bars, each of which connects terminals of adjacent cells; and a sensor device configured to detect a voltage of each cell. The sensor device is disposed above the plurality of bus bars disposed on an upper surface of the cell-stacked body as viewed from a width direction perpendicular to a stacking direction and an up-down direction, and includes a connector having a connection portion in the width direction. Each of the bus bars has a bent portion protruding upward between the cells to be connected. The connector is disposed between the bent portions of adjacent bus bars in the stacking direction, and a lower surface of the connector is provided at a position lower than an upper portion of the bent portion in the up-down direction.

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, as shown in Patent Document 1, in a battery module in which a sensor device is arranged on the upper surface of a battery cell stack, the height dimension may increase significantly. In particular, in a battery module using a bus bar having an upwardly protruding bent portion in the middle of the stacking direction of the battery cells in order to relieve the stress acting on the battery cells due to expansion, the height dimens...
