Abstract

The invention discloses a lead-acid cell bus-bar pole, characterized by comprising a pole and a bus-bar which is arranged at the bottom of the pole; wherein the bus-bar comprises a collecting area and a welding area; the collecting area is a converging surface structure, and a contracting area of the collecting area is fixedly connected with the pole while an opening area is connected with the welding area; the welding area is a spaced tooth-shape structure, and the size of a tooth seam is matched with a lug of a cell pole plate. The bus-bar pole of the invention can be used for welding the cell pole plate between the tooth-shape structures without compensating lead while welding. The bus-bar pole of the invention can be welded shallowly along the edge of the tooth seam, the welding surface is thin and the internal structure of the cell pole plate cannot be damaged. The bus-bar pole of the invention does not need to compensate lead.

Description

technical field

[0001] The invention relates to a component of a lead-acid battery, in particular to a lead-acid battery bus bar pole and a method for using the pole to weld battery pole groups. Background technique

[0002] The quality of the lead-acid battery mainly depends on whether the battery can be "fully charged" and reach the normal running time state under the condition of charging according to the specified time and current value. During the charging and discharging process of the battery, the temperature rise is small and the water consumption is less. The battery life is long and the quality is good. At present, traction-type lead-acid batteries in the United States and Germany can achieve a working life of more than 2 years. However, the warranty period of domestic traction-type lead-acid batteries is difficult to exceed one year. In this year, the after-sales service due to the three guarantees of quality is always happening non-stop.
