Description
【考案の詳細な説明】
本考案は複数の電池からなる電池パックに関するもので
ある。[Detailed Description of the Invention] The present invention relates to a battery pack consisting of a plurality of batteries.
従来円筒型電池からなる電池パックは第１図に示す如く
多数のセルを配列集合した電池群１の上面と下面に合成
樹脂の平板状絶縁板３を装着した全体を合成樹脂フィル
ムからなる包装体２により包装しているが、電池の充電
、放電の際に電池に発生する熱を外部へ逃がすことが難
がしく、そのため包装体である合成樹脂フィルムが熱で
収縮したり、また電池に悪影響を及ぼす等の欠点があっ
た。Conventional battery packs consisting of cylindrical batteries are packaged as a whole made of synthetic resin film, with flat insulating plates 3 made of synthetic resin attached to the top and bottom surfaces of battery group 1 in which a large number of cells are arranged and assembled, as shown in Fig. 1. However, it is difficult for the heat generated in the battery to escape to the outside when charging and discharging the battery, and as a result, the synthetic resin film that is the packaging body may shrink due to heat, and it may have a negative effect on the battery. There were disadvantages such as causing
本考案は上記欠点を除去するためになされたもので、そ
の一実施例を第２図につき説明すれば、円筒型の電池か
らなる電池群１の上面に凹凸を有するポリプロピレンの
絶縁板３を装着し包装体２として合成樹脂フィルム、例
えば塩化ビニールフィルムにより全体を包装し電池パッ
クを構成した。The present invention has been made to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described with reference to FIG. The package 2 was entirely wrapped with a synthetic resin film, such as a vinyl chloride film, to form a battery pack.
絶縁板３に凹凸を設けたことにより該絶縁板３と電池群
１との間に通風を良くする充分な空間４が形成され、電
池の充電、放電等により発生する熱が外部へ逃げ易くな
り、電池パック内に熱がこもることがなく、包装体２で
ある合成樹脂フィルムの熱による収縮、また絶縁板３の
変形もなく、更に電池温度の上昇も減少されるので、電
池性能に及は゛す悪影響も防止することが出来る。By providing unevenness on the insulating plate 3, a sufficient space 4 for improving ventilation is formed between the insulating plate 3 and the battery group 1, and the heat generated by battery charging, discharging, etc. can easily escape to the outside. Since heat does not accumulate inside the battery pack, there is no shrinkage of the synthetic resin film that is the packaging body 2 due to heat, there is no deformation of the insulating plate 3, and the increase in battery temperature is also reduced, so battery performance is improved. Negative effects can also be prevented.
凹凸はその凹部に電池及びその突出端子５が嵌入しない
ように配設することが肝要である。It is important to arrange the unevenness so that the battery and its protruding terminals 5 do not fit into the recessed portion.
また従来は発熱の危険性から容量の大きい電池について
は出荷時の充電を電池パックにすることなく行っていた
が、本考案によれば電池パックのよ・出荷時の充電を行
うことが出来る。Furthermore, in the past, large capacity batteries were charged at the time of shipment without the battery pack due to the risk of heat generation, but according to the present invention, the battery pack can be charged at the time of shipment.
以上の如く本考案は少なくとも一側面に電池の突出端子
より小径の凹凸を多数設けた絶縁板を該凹凸が電池に接
するよう上面および下面に装着された電池群を包装体２
により包装し、該電池群と絶縁板の間に空間を形成して
なる電池パックであるため、電池の充電時に発生する熱
の外部への放散を容易にし、電池パックの包装体の熱に
よる収縮、損傷を防ぎ、電池の性能劣化がなく容量の大
きな電池にも安心して適用出来る電池パックを得ること
が出来、実用上の利用価値が大である。As described above, the present invention provides a packaging body for a group of batteries in which an insulating plate having a large number of concavities and convexities smaller in diameter than the protruding terminals of the batteries on at least one side is attached to the upper and lower surfaces of the insulating plate so that the convexities and convexities are in contact with the batteries.
Since this is a battery pack that is packaged with a battery pack and a space is formed between the battery group and an insulating plate, it is easy to dissipate the heat generated when charging the batteries to the outside, and prevent shrinkage and damage of the battery pack packaging due to heat. It is possible to obtain a battery pack that can be safely applied to large-capacity batteries without deterioration of battery performance, and has great practical utility value.
