The battery pack of the present invention accommodates a first battery holder 3A and a second battery holder 3B having a housing part 4 for housing a plurality of unit cells 1, and a housing for the first battery holder 3A and the second battery holder 3B. It is equipped with the unit cell 1 set in the part 4. The first battery holder 3 </ b> A and the second battery holder 3 </ b > B include all the unit cells 1 constituting the first cell unit 8 formed by connecting a unit cells (a is an integer of 3 or more) in parallel. And a partial storage portion 7 capable of storing a number of unit cells 1 constituting the second battery unit 8. The a unit cells 1 housed in the entire housing portion 6 of the first battery holder 3A and the second battery holder 3B are connected in parallel to each other to form a first battery unit 8. Further, the b unit cells 1 are stored in the partial storage portion 7 of the first battery holder 3A , and the (ab) unit cells 1 are stored in the partial storage portion 7 of the second battery holder 3B. Then, the a unit cells 1 housed in the partial housing portions 7 of the first battery holder 3A and the second battery holder 3B are connected in parallel to constitute the second battery unit 8. . The battery pack includes a first battery unit 8 and a second battery unit 8 that are configured by the unit cells 1 that are housed in the housing portions 4 of the first battery holder 3A and the second battery holder 3B. Connected.
Further, in the battery pack of the present invention, a part of the partial storage portion 7 of the second battery holder 3B can be an empty storage portion 4X in which the unit cell 1 is not stored.

以上のバッテリパックは、同じ電池ホルダーを使用しながら、並列接続される素電池の個数を調整して、用途に最適な個数に素電池を並列接続し、電池ホルダーの外形を変更することなく用途に最適な出力特性にできる特徴がある。それは、第２の電池ユニットを構成する素電池を第１の電池ホルダー及び第２の電池ホルダーに分割して収納すると共に、第１の電池ホルダー及び第２の電池ホルダーに同じ個数の素電池を収納することなく、片方の電池ホルダーに１個少なく素電池を収納するからである。また、一方の電池ホルダーには、電池が収納されない空収納部ができるので、この部分を放熱スペースとすることで、素電池の放熱をより効果的にできる特徴も実現する。
The above battery pack uses the same battery holder, adjusts the number of cells connected in parallel, connects the cells in parallel to the optimum number for the application, and uses it without changing the outer shape of the battery holder. There is a feature that can achieve the optimum output characteristics. That is, the unit cells constituting the second battery unit are divided and stored in the first battery holder and the second battery holder, and the same number of unit cells are placed in the first battery holder and the second battery holder. This is because one unit cell is housed in one battery holder without housing. In addition, since one battery holder has an empty storage part in which no battery is stored, a feature that can effectively dissipate the unit cell can be realized by making this part a heat dissipation space.

本発明のバッテリパックは、収納部４に素電池１を収納してなる第１の電池ホルダー３Ａ及び第２の電池ホルダー３Ｂを連結して電池ブロック２を構成し、さらに、複数の電池ブロック２が、直列又は並列に接続することができる。
以上のバッテリパックは、連結する電池ブロック２の個数を調整して、用途に最適な出力電圧や出力電流にできる特徴がある。
In the battery pack of the present invention, a battery block 2 is formed by connecting a first battery holder 3A and a second battery holder 3B, each of which contains a unit cell 1 in a storage section 4, and a plurality of battery blocks 2 are further connected. but it may be connected in series or in parallel.
The battery pack described above is characterized in that the number of battery blocks 2 to be connected can be adjusted so that the output voltage and output current are optimum for the application.

本発明のバッテリパックは、第１の電池ユニット８及び第２の電池ユニット８を、３個ないし９個のいずれかの奇数個の素電池１で構成することができる。
以上のバッテリパックは、並列接続される素電池で出力電流を用途に最適な容量にできる。
In the battery pack of the present invention, the first battery unit 8 and the second battery unit 8 can be constituted by any odd number of 3 to 9 unit cells 1.
The above battery packs can be configured to have an output current having an optimum capacity for the intended use with the cells connected in parallel.

本発明のバッテリパックは、空収納部４Ｘを第２の電池ホルダー３Ｂの中央部に配置することができる。
以上のバッテリパックは、空収納部を内部に配置するので、電池ホルダー内部の発熱量を少なくできる。このため、各々の素電池の放熱差を少なくして温度差を少なくし、素電池の劣化や電気特性の低下等のアンバランスを少なくできる。
Battery pack of the present invention, can place an empty storage unit 4X the center portion of the second battery holder 3 B.
Since the above battery pack has the empty storage portion disposed therein, the amount of heat generated inside the battery holder can be reduced. For this reason, the heat dissipation difference of each unit cell can be reduced to reduce the temperature difference, and unbalances such as deterioration of the unit cell and deterioration of electrical characteristics can be reduced.
