摘要:
A method of controlling a battery storing electric power generated by a power generator generating electric power using renewable energy, comprising: computing a output value for the electric power to be supplied to an electric power transmission system based on a predetermined maximum charge rate of the battery, and a predetermined maximum discharge rate for the battery; and supplying to the electric power transmission system with electric power corresponding to the output value from at least one of the power generator and the battery.

In a stack type battery, stacked positive and negative electrode lead tabs (11, 12) are joined to one another at a location between the current collector terminals and the electrode plates, the positive and negative electrode lead tabs (11, 12) being folded at an intermediate location between positive and negative electrode current collector terminals (15, 16) and positive and negative electrode plates and protruding from the positive and negative electrode plates. A stacked electrode assembly (10) is accommodated in a battery case (18) having flexibility. A first spacer (a first cover portion (52) of an integral-type spacer (5)) is disposed between the battery case (18) and an open side end of the positive and negative electrode lead tabs (11, 12) formed by folding the positive and negative electrode lead tabs (11, 12).

A stack type battery has a stacked electrode assembly (10) disposed in a reduced pressure condition in an accommodating space within a square-shaped laminate battery case (25) formed by melt-bonding peripheral edges of two laminate films (28) to each other. A positive electrode current collector terminal (15) is joined to positive electrode current collector tabs (11) being overlapped with each other, and a negative electrode current collector terminal (16) is joined to the negative electrode current collector tabs (12) being overlapped with each other. An insulative spacer (30) for compressing welded portions (36) between the positive and negative electrode current collector tabs (11, 12) and the positive and negative electrode current collector terminals (15, 16) is disposed in a tab-connecting space existing between the stacked electrode assembly (10) and an inner face of the laminate battery case (25) from which the positive and negative electrode current collector terminals (15, 16) protrude. An inward displacement restricting protrusion (31) for restricting inward displacement of the positive and negative electrode current collector terminals (15, 16) is provided at a location of the spacer (30) that corresponds to a region between the positive and negative electrode current collector terminals (15, 16).
摘要:
A laminate type battery includes a laminate battery case and an electrode assembly. The laminate battery case includes two laminate films each having a metal layer and plastic layers provided on both faces of the metal layer, and has a welded portion in which peripheral edges of the two laminate films are welded to each other. The electrode assembly is enclosed in the laminate battery case, and has a positive electrode plate, a negative electrode plate, and a separator disposed therebetween. An internal gas pressure sensing portion, in which the inner plastic layer of each of the laminate films is absent and the metal layers are in contact with each other so as to be in an electrically conductive state, is formed in a portion of the welded portion. A voltage detection hole, in which the outer plastic layer is absent and the metal layer is exposed, is formed in a surface of each of the two laminate films.
