Abstract

PURPOSE:To obtain the desired and stable welding quality wherein any one of plural joints does not exert any influence upon welding of other joints by a method wherein each strap is provided with a joint and respective joints facing each other through a partition are connected to each other, by resistance welding. CONSTITUTION:In case adjacent cells are connected to each other, joints 7 and 7', 8 and 8' are fitted in a hole 3 of a partition 2 from both sides, the respective joints facing each other, namely, the joints 7 and 8 as well as the joints 7' and 8' are respectively brought in contact with each other in the hole 3 to allow conduction of a resistance welding current for welding connection between 7 and 8, followed by welding connection between 7' and 8' by the same method. Thereby the order of welding between the joints 7 and 8 as well as the joints 7' and 8' shall be arranged in such a way that the respective straps are electrically isolated because it is so composed that the positive electrode strap is divided into 5 and 5' while the negative electrode strap is divided into 6 and 6'.

Description

DETAILED DESCRIPTION OF THE INVENTION XQ Ming relates to a method for manufacturing an M battery in which adjacent cells in a monoblock 1# battery are connected by resistance welding.

In monoblock type buckwheat batteries that have multiple cells and have a structure in which adjacent cells are connected through partition walls, when the number of plates per cell becomes large, it is difficult to connect from the end of the strap to the intercell connector. As the distance becomes longer, the drop of electrons at the strap portion increases, which has the disadvantage of deteriorating the gravity characteristics during high rate discharge. For this reason, conventionally, a plurality of connecting bodies between adjacent cells are provided between one strap, and a high resistance region is provided between the straps of the plurality of connecting bodies,
Then, use the Taiichi style between the connecting bodies to be connected. A method of manufacturing a storage battery has been proposed in which resistance welding is performed at one time, but in this method of manufacturing a high-voltage battery, the height of the high resistance area is 1 m, and the connection body is resistance welded by using a large flow change. When connecting one of the circles of multiple connecting bodies, when the other connecting body is in contact or has already completed the habitual contact, the m-contact current flows between the multiple connecting bodies. To prevent the risk of not being able to obtain a constant indirect result due to the occurrence of shunt current depending on the electrical resistance of the connecting body and the strap, a high-resistance zone is provided between each strap to reduce the welding ME flow. The aim is to reduce the diversion of water.

However, in manufacturing a storage battery with such a structure, 'M,
As long as there is a weak circuit, it is impossible to avoid any shunt current, and when attempting to weld in a T-field where the magnitude of the welding current shunt changes due to the electric resistance on each side of the connected body being 1. As a result, it becomes difficult to maintain a predetermined welding result, and as a result, it becomes difficult to maintain a predetermined welding result. This method is disadvantageous in that it is extremely complicated to manufacture the device, and furthermore, energy consumption increases by 1 to compensate for the current that becomes ineffective due to the shunt, and the load on the device increases.

The present invention eliminates the drawbacks mentioned above, and has the functions of irises release characteristics, vibration resistance, impact resistance, and weight efficiency of conventionally devised storage batteries. The present invention provides a method for manufacturing a storage battery that makes maintenance and management of quality as easy as the existing method for manufacturing a storage battery having a single reader.

That is, the present invention is an intelligent method for a storage battery of m construction in which adjacent cells are connected by resistance indirect 1ζ with a plurality of connectors, and the positive FIJA hypothesis of one of the N11Fij groups connected through the partition wall is used. and the other one temporary group are divided into a plurality of groups, and divided into the second Vi groups r: IEt+I
G board, Negative 1 and other temporary strumps should be set up for each state Cζ
, by inserting a connecting body into each suction body, and by connecting the connecting bodies facing each other through the wall by resistance welding, each of the plurality of connecting bodies is connected to the other suction body. The object of the present invention is to provide a method for manufacturing a battery capable of obtaining a predetermined stable welding quality without affecting welding at all.

Next, onto the drawings! The method for repairing a storage battery of the present invention will be specifically explained using an example. Fig. 1 and Fig. 2 show an example of the fabrication method of the present invention, and Fig. 8 shows the fabrication method of the invention. An example of the configuration is shown.
