Embodiment Construction

[0030] figure 1 In A, a plan view of the power storage device 30 according to the first embodiment is shown. The storage capacitor 10 houses an electricity storage laminate (electricity storage structure) 11 . The planar shape of the storage container 10 is, for example, a rectangle with a slightly rounded apex. The electricity storage stack 11 includes a first collector electrode 21 , a second collector electrode 22 , a separator 25 , a first polarity-specific electrode 27 , and a second polarity-specific electrode 28 . The first collector electrode 21 and the second collector electrode 22 are stacked and arranged with the spacer 25 interposed therebetween so as to overlap each other in their respective partial regions and not to overlap in other regions. A first polarity division electrode 27 and a second polarity division electrode 28 are arranged at the overlapping portion of the two collector electrodes 21 and 22 .

[0031] The first divided polarity electrode 27 and ...

Abstract

The invention provides a power storage device, a power storage module and a working machine connected with relatively few wires. The power storage device provided by the invention comprises a container, a pair of electrodes leading to the outside from the inside of the container, a power storage structure sealed and arranged inside the container and connected with the pair of the electrodes, and an electronic circuit substrate formed with the electronic circuit which is electrically connected between the pair of the electrodes, wherein the electronic circuit substrate is mechanically fixed on one side of the pair of the electrodes through a first conductive part, and one side of the pair of the electrodes is electrically connected with the electronic circuit through the first conductive part.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2011-134485 filed on June 16, 2011. The entire content of the application is incorporated in this specification by reference. [0002] The invention relates to an electrical storage device connected with an electronic circuit substrate, an electrical storage module electrically connected to a plurality of electrical storage devices, and a working machine equipped with the electrical storage module. Background technique [0003] The development of hybrid working machines using electric storage blocks such as rechargeable secondary batteries and electric double-layer capacitors is advancing. As an electricity storage block used in a hybrid working machine, a plate-shaped electricity storage block in which an electricity storage element is wrapped with a laminated film has been proposed. In the laminate type electricity storage block, positive electrode tabs and negative electrode...
