Abstract

Since a plurality of storage elements (11) are electrically connected to each other, and the part of the peripheral surface of the storage elements (11) that is accommodated in the concave surface (29) and the concave surface (29) are sealed with double-sided adhesive tape (35). Therefore, the energy storage element (11) can be firmly fixed to the bracket (27), and the heat of the energy storage element (11) can be efficiently conducted to the bracket (27) via the double-sided adhesive tape (35). .

Description

technical field [0001] The present invention relates to an electric storage unit that stores electric power in an electric storage element and discharges the electric power when necessary. Background technique [0002] Conventionally, in order to store electric power and discharge the electric power when necessary, electric storage units constructed using electric storage elements such as a plurality of secondary batteries and large-capacity capacitors have been widely used (for example, refer to Patent Document 1 and Patent Document 2). . [0003] Hereinafter, prior art related to such an electric storage unit will be described with reference to the drawings. [0004] Figure 7 It is an exploded perspective view showing the overall structure of a conventional electric storage unit. Here, the battery pack disclosed in Patent Document 1 is shown as the electric storage unit. like Figure 7 As shown, in this battery pack, a plurality of batteries 101 are arranged in a stacke...
