摘要:
On the opposite end walls of a flat, prismatic battery case of a battery module where electrode terminals are attached, protruding components are formed such as to protrude further than the electrode terminals. Terminal holes are formed in the end walls in which the electrode terminals are fitted, and the thickness of the end walls of the integral battery case in the vicinity of the terminal holes is not the same on both sides of each of the terminal holes. Also, one or a plurality of vertical and horizontal ribs are formed on the end walls between the electrode terminals and the protruding components. Further, a sealing structure is included for a battery.

A battery pack is constructed with a plurality of battery modules. Each battery module comprises a plurality of prismatic cell cases having short lateral walls and long lateral walls and respectively accommodating elements for electromotive force, these cells being mutually coupled sharing their short lateral walls as partition walls, thereby constituting an integral battery case. Electrode terminals of positive and negative polarities are arranged at longitudinal opposite ends of the integral battery case. Projections and indentations for positioning the plurality of battery modules when coupling them together with their long side faces abutted each other to constitute the battery pack are formed substantially in the center of given cell cases positioned symmetrical with respect to the centerline in the lengthwise direction of the battery module.
摘要:
A plurality of cells each encased in prismatic cell cases having short lateral walls and long lateral walls are arranged side by side, with adjacent short lateral walls being integral with each other, thereby constituting an integral battery case. The upper open ends of the plurality of prismatic cell cases are integrally closed by a single lid member. Each of the cells accommodates therein a group of electrodes stacked alternately upon one another parallel to the long lateral walls of the cell cases with intervening separators therebetween. Neighboring cells are connected in series at their abutting lateral opposite ends with each other.
摘要:
A battery module includes a plurality of cells accommodating an electrode plate group and an electrolyte, and a single integrated battery case for accommodating the plurality of cells. The ratio of the component resistance including the connecting resistance between the cells to the reactive resistance of the electrode plate group and the electrolyte in each cell, is set in the range of 1:99-40:60 at a temperature of 25° C. Thereby, the internal resistance per cell is reduced, and higher power output and improved service life characteristics are achieved.

A group of electrodes are accommodated in a prismatic cell case of a rechargeable battery. Intervening separators are provided between positive and negative electrode plates arranged alternately in parallel to long lateral walls of the cell case. The positive electrode plates each include a lead portion having a surface on which at least one lead plate is attached. Lateral edges of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edges of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side. The protruding portions form the lead portions. Upper open ends of the cell cases are closed by an integral lid member.

In each of the cells that constitute an battery module, a plurality of positive electrode plates and negative electrode plates are layered parallel to the long lateral walls of prismatic cell cases with intervening separators therebetween, wherein lateral edge portions of the positive electrode plates protrude beyond the negative electrode plates on one side, and lateral edge portions of the negative electrode plates protrude beyond the group of positive electrode plates on the opposite side, the protruding portions forming lead portions.
摘要:
A battery module is provided which includes multiple rechargeable batteries coupled together. The battery module includes multiple prismatic cell cases having short lateral walls and long lateral walls arranged side by side. Adjacent short lateral walls are integral with each other. The battery module includes holes extending through the short lateral walls of the cell cases at upper edge portions. The battery module also includes a pair of frame fittings that have base ends and protruding portions in each of the cell cases for connecting two adjacent cell cases. The protruding portions of the pair of frame fittings extend into the through holes in the upper edge portions of the short lateral walls of the cell cases from both sides and are welded together. Positive and negative electrode collector plates in the cell cases are respectively attached to the base ends of the frame fittings. End frame fittings that have base ends and protruding portions for cell cases are located at both outer ends of the rechargeable battery for connecting the cell cases to outside terminals. Connection terminals that have protruding portions are connected to the end frame fittings at both outer ends of the rechargeable battery.
摘要:
A nickel metal hydride storage battery included a battery case, and a group of electrode plates arranged in the battery case, wherein the battery case includes a battery case main body having a hole and a lid for closing the hole. The battery case includes a first portion made of a metal or a laminate of a metal and a resin, and a second portion made of a resin; and an area of the first portion is 20% or more and 90% or less with respect to the entire battery case. Thus, a nickel metal hydride storage battery is capable of controlling the amount of hydrogen permeating the battery case and capable of suppressing the long-term deterioration.
