Description

Technical Field

[0001] This utility model relates to the field of submersible cell module technology, specifically to a CCS structure for submersible energy storage cell module. Background Technology

[0002] The Computational Storage System (CCS) is a key technology used in energy storage systems. The main function of the CCS is to centralize the energy output of energy storage devices (such as battery packs and supercapacitors) onto a single integrated busbar for effective energy management and distribution. By connecting and integrating multiple energy storage units, the CCS achieves centralized energy management. It can monitor and control the status of each energy storage unit, ensuring balanced and optimized energy utilization. Furthermore, the CCS provides voltage and current stability, as well as short-circuit protection and fault isolation functions, guaranteeing the safety and reliability of the system.

[0003] Traditional CCS is used for air-cooled and liquid-cooled cell modules, and FPC (flexible printed circuit board) is designed between serial modules. However, immersion cell modules do not allow FPC to be designed in the middle, so this problem urgently needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a CCS structure for an immersion energy storage cell module. The structure is simple and integrates the flexible circuit board for data acquisition on the side of the module to replace the commonly used FPC in the middle. This solves the problem that immersion cell modules do not allow for the design of FPC in the middle. At the same time, the acquired voltage and temperature also have excellent stability.

[0005] To address the aforementioned technical problems, this utility model provides an immersion energy storage cell module (CCS) structure, comprising spaced-apart cells, a cover plate at the top of each cell, a series aluminum bar connecting two adjacent cells on the cover plate, output aluminum bars on both sides of the cover plate, and a flexible circuit board for data acquisition surrounding the cell on the side of the cell. The output aluminum bars and the series aluminum bars are connected to the flexible circuit board for data acquisition via a sampling nickel strip. A patch connector is located on the cover plate near the output aluminum bars and is connected to the flexible circuit board for data acquisition.

[0006] Furthermore, a protective shell is provided on the outer side of the cover plate.

[0007] Furthermore, the battery cell is provided with circumferential cable ties on both the top and bottom sides.

[0008] Furthermore, the cable ties are made of steel.

[0009] Furthermore, a temperature sensor is installed on the pressure-sensing nickel sheet.

[0010] Furthermore, the cover plate is made of PET thermoformed insulating material.

[0011] Furthermore, foam is provided at the bottom of the patch connector.

[0012] Furthermore, the cover plate is provided with placement slots corresponding to the positions of the serial aluminum bar and the output aluminum bar, and a positioning shaft is provided in the placement slot.

[0013] The beneficial effects of this utility model are as follows: This device integrates the flexible circuit board for acquiring the circuit onto the side of the module to replace the commonly used FPC with a central design, which solves the problem that immersion cell modules do not allow for the design of an FPC in the middle. At the same time, the acquired voltage and temperature also have excellent stability. Attached Figure Description
