Battery and charging and discharging equipment connecting device

Abstract

The invention relates to the technical field of battery testing, and provides a battery and charging and discharging equipment connecting device. The connecting device for a battery and charging and discharging equipment comprises two connecting terminals, each connecting terminal is provided with a conductive unit used for connecting the battery and the charging and discharging equipment, and oneof the two conductive units is used for connecting a positive tab of the battery and a positive cable of the charging and discharging equipment. The other one of the two conductive units is used forconnecting a negative pole lug of the battery and a negative cable of the charging and discharging equipment; and the connecting terminals are provided with connecting pieces capable of respectively contacting and connecting the cables and the tabs with the conductive units. According to the connecting device, the rapid connection of the cable and the battery tabs can be realized, the operation difficulty in the connecting process is effectively reduced, and meanwhile, the pulling force of the cables acts on the connecting terminals, so that the pulling force of charging and discharging cableson the tabs can be avoided, and the damage probability of the tabs in the mounting process is reduced.

Description

technical field [0001] The invention relates to the technical field of battery testing, in particular to a connection device between a battery and charging and discharging equipment. Background technique [0002] After the production of lithium batteries is completed, a series of tests are required, such as charging and discharging performance tests. The traditional connection method is to screw the two tabs of the battery with the positive and negative cables of the charging and discharging equipment respectively. The specific connection method as follows: [0003] Align and stack the round holes of the battery tabs and the round holes of the cable terminals concentrically, use bolts to pass through the round holes, and then use nuts to tighten them, and then wrap insulating tape on the screw connection area as an insulation protection measure; keep the cables in a natural bending state . [0004] However, the existing connection method has the following disadvantages: ...

AI Technical Summary

Problems solved by technology

[0005] Generally, the cables of charging and discharging equipment are relatively thick, and the reaction force is large. During the installation process, it is difficult to stack the cable terminal surface and the tab surface in parallel. The operation is difficult, and it is difficult for an operator to implement. The current connection method Installers have high operating proficiency requirements

[0006] In addition, if the test time is long, the battery tabs will be under stress for a long time, or when the cable is moved, the tabs will be easily cracked or even broken due to the pulling force, and the damage of the tabs will reduce its cross-sectional area and reduce the overheating. Current capability, adding uncertain factors to test data and affecting test results
