Problems solved by technology

Two wires need to be welded at the same time to connect the middle tab of the battery, and the thickness of the entire battery pack is bound to increase. At the same time, the connection operation is inconvenient, the cost is high, and the appearance is not beautiful, and the battery tab is directly welded to the wire. High temperature will make the battery The seal is loose, so the battery pack is at risk of leaking fluid and short circuit

Embodiment Construction

[0019] The structure of the battery pack is mainly described below in conjunction with the accompanying drawings.

[0020] Such as Figure 1a-1c As shown, the battery pack includes a first battery 10 , a second battery 20 and a connecting device 30 for connecting the first battery 10 and the second battery 20 .

[0021] The grooves formed by the cells of the first battery 10 and the second battery 20 and the aluminum shrink film are provided with tab structures for drawing out the polarity of the cells. Such as Figure 2a-2c Shown is a schematic diagram of the structure of the connection device of the battery pack. The connection device 30 of the battery pack is in the shape of a strip sheet, including a connection body and four welding points 311, 312, 313 arranged on the lower surface 310 of the connection body and welded to the tabs of the two batteries. , 314 and 3 wire contacts 321, 322, 323 that are arranged on the upper surface 320 of the connection body and are conne...

Abstract

The invention relates to a battery pack comprising a connecting device connected with two batteries. The connecting device is in a strip-type sheet shape and comprises a soldering point arranged on the lower surface of the connecting device and soldered with cathode tabs and a wire joining arranged on the upper surface of the connecting device and connected with an external wire. One surface of the sheet-shaped connecting device is soldered with the cathode tabs of the batteries, and the other surface is connected with the external wire, which avoids that two wires are simultaneously soldered on the cathode tabs of the middles of the batteries and effectively reduces the thickness of the battery pack.

Description

【Technical field】 [0001] The invention relates to the field of battery manufacturing, in particular to a battery pack. 【Background technique】 [0002] The traditional battery cell connection design uses wires to directly weld the tabs of the two batteries, and then uses insulating materials to insulate the connection. Two wires need to be welded at the same time when the battery is connected to the middle tab, and the thickness of the entire battery pack will inevitably increase. The seal is loose, and the battery pack is at risk of bulging, leaking, and shorting. 【Content of invention】 [0003] Based on this, it is necessary to provide a thin battery pack. [0004] A battery pack, comprising a first battery and a second battery, the first battery and the second battery are provided with tabs, and a connection device connected to the first battery and the second battery, the connection device is It is in the shape of a strip sheet, including a connecting body, a welding...
