Problems solved by technology

However, in order to adjust the battery pack or secure the positions of the plates and connection members stably, special jigs and careful techniques are required, which complicates the manufacturing process.
[0009] Thus, in the conventional assembled battery, the assembly of the components for limiting the battery stack is a complicated process, and there is a problem that the productivity is lowered.

Abstract

The invention provides a battery pack capable of improving the productivity with a simple structure. The battery pack (470) includes a stack including a plurality of battery cells (50) aligned, holding plates (411R, 411L) respectively provided on two side faces of the stack, a coupling member (440) disposed along a direction in which the battery cells (50) are aligned and fixed to the holding plates (411R, 411L) to bind the plurality of battery cells (50), and a distribution board (450) serving as an insulating member provided between the coupling member (440) and the plurality of battery cells (50). The surface of the distribution board (450) includes projecting ribs (452a, 452b) disposed adjacent to and along at least one of side faces of the coupling member (440) and projecting toward the coupling member (440).

Description

[0001] This application is a divisional application of the application with the application number 201310011004.5, the application date is January 11, 2013, and the invention title is "Battery Pack and Power Supply Device". technical field [0002] The present invention relates to a battery pack composed of, for example, a plurality of stacked secondary batteries, and a power supply device using the same. Background technique [0003] Secondary batteries are widely used not only as replacements for primary batteries, but also as power sources for electronic equipment such as mobile phones and IT equipment. In particular, nonaqueous electrolyte secondary batteries typified by lithium ion secondary batteries are being applied to electric vehicles and large industrial electronic devices due to their high energy density. For this reason, in order to obtain a higher voltage, non-aqueous electrolyte secondary batteries as single cells are also stacked to constitute a battery pack....
