[0003] However, there are two ways of balancing the energy storage system on the market today: one is to open the cover of the energy storage module and use the alligator clips of the balancing instrument to clamp the aluminum busbar to balance the charge and discharge of each cell; the other is to open the front cover of the battery management unit of the energy storage module and connect it to the voltage line in the FPC board of the battery module to ultimately achieve the purpose of optimizing the charge state consistency of the single cells in the battery cluster and reducing the pressure difference within / between clusters.

[0004] The balanced connection methods described above have many disadvantages:

[0005] a. At the actual energy storage project site, some customers do not allow the energy storage plug-in box to be opened on site;

[0006] b. Even with the customer's permission, opening the battery module will result in a decrease in airtightness and insulation performance, causing the product to deviate from the end-of-line inspection standards;

[0007] c. Opening and balancing the cover is time-consuming and laborious, which greatly increases the cost of project inspection and maintenance;

[0008] d. Opening the cover increases the risk of product damage, short circuit and ignition, causing the entire battery module to be scrapped, and in serious cases, open flame safety accidents may occur.

[0009] Therefore, it is urgent to develop a balancing quick plug for energy storage battery modules. Solving the above problems can better integrate balancing instruments and methods into the application of energy storage batteries. Utility Model Content

[0016] In the above-mentioned fast equalization socket of the energy storage battery module, the copper wire is welded to the positive electrode or the negative electrode of the energy storage battery through the nickel sheet.
