本発明はモノブロツク式蓄電池における隣接す

分流を少なくすることにある。 In a monoblock storage battery that is equipped with multiple cells and has a structure in which adjacent cells are connected through partition walls, as the number of electrode plates per cell increases, the distance from the end of the strap to the intercell connector increases. Since the length of the strap becomes longer, the voltage drop at the strap portion increases and the voltage characteristics during high rate discharge deteriorate. For this reason, conventionally, a plurality of connecting bodies between adjacent cells are provided on one strap, a high resistance region is provided between the straps of the plurality of connecting bodies, and a large current is passed between the connecting bodies. A method of manufacturing a storage battery has been proposed in which resistance welding is performed instantaneously using a high current. When welding one of multiple connecting bodies, if the other connecting body is in contact or has already been welded, the welding current will increase the electrical resistance of the multiple connecting bodies and the strap. In order to prevent the risk of not being able to obtain a desired welding result as a result of a shunt occurring in response to the welding current, a high resistance region is provided between the straps to reduce the shunt of the welding current.

さらには分流により無効となる電流を補償する分
だけ消費エネルギーが増すため、装置の負荷が拡
大する欠点がある。 However, even in the manufacture of storage batteries with such a structure, it is impossible to completely eliminate shunt current as long as an electrical circuit exists, and the magnitude of the shunt current of the welding current changes as the electrical resistance of each connected body differs. As a result, there are variations in the welding current of the connection body parts that are actually being welded, making it difficult to maintain a predetermined welding result. It becomes extremely complicated to manufacture the device,
Furthermore, since energy consumption increases by the amount of current that is made ineffective by the shunt, there is a drawback that the load on the device increases.
