Description

Technical Field

[0001] The utility model relates to the technical field of capacitor module connection copper bars, in particular to a super capacitor module connection copper bar. Background Art

[0002] Super energy capacitors have a wide range of uses. They can be used as a power balancing power source for lifting equipment and can provide ultra-large current power; they can be used as a vehicle starting power source, with higher starting efficiency and reliability than traditional batteries, and can fully or partially replace traditional batteries; they can also be used as photovoltaic + energy storage power storage devices. The combination of photovoltaic power generation and super energy capacitor power storage can largely solve the problem of difficult wiring in various power usage scenarios and improve energy utilization efficiency. Among them, super energy capacitors belong to the category of power batteries.

[0003] In the application of super capacitors, multiple cells are generally assembled in series or in parallel to form a super capacitor module, and the positive and negative electrodes of the super capacitor module are used for output. In order to manage the overcharge and over-discharge phenomenon of the super capacitor module, we need to collect signals such as the voltage, temperature, and charge and discharge current of the single cell. Therefore, it is necessary to install a nickel-plated copper strip in the cell bracket mounting groove at the connection of the tabs of the two cells in the super capacitor module, and use laser welding to weld the cell tabs and the copper strips together. After the copper strips are nickel-plated, they cannot be tinned, so the signal collection wires cannot be connected. In the manual PACK power battery module, the common method is to sandwich a copper sheet for convenient welding between the tabs and the copper strips to facilitate the welding of the signal collection line. In the automatic PACK line of the power battery, if a copper sheet for welding is added, the PACK process will be very complicated. In view of this, it is necessary to modify the copper strip structure of the manual PACK to meet the automatic PACK requirements of the super capacitor module. Utility Model Content
