Description

Technical Field

[0001] This utility model relates to a wire harness CCS structure, and more particularly to a storage battery wire harness CCS structure with a built-in fuse. Background Technology

[0002] Energy storage batteries not only play a key role in ensuring a stable energy supply and improving energy efficiency, but also drive the vigorous development of the new energy industry, profoundly impacting our lives and future.

[0003] In the current CCS assembly, surface mount fuses are usually used in FPC solutions. The process involves the preparation of copper foil laminate, material cutting and drilling, the creation of serrated structures, chemical copper plating and electroplating, outer layer pattern transfer and circuit pattern fabrication, and finally the formation of the surface mount fuse. This process is not only complex in design and involves many steps, but also has high production costs. The wire harness solution typically uses ultrasonic welding of the wire harness and aluminum bar for voltage sampling. Since there is no fuse on the wire harness, the current will increase sharply when a short circuit occurs, which cannot protect the power supply and equipment. Under the condition of high current, the components in the circuit are at risk of being damaged.

[0004] Therefore, it is necessary to develop a CCS structure for energy storage battery harnesses with built-in fuses to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a CCS structure for energy storage battery harnesses with integrated fuses.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a CCS structure for energy storage battery harness with built-in fuse, including an isolation plate, one end of which is equipped with a No. 1 output electrode and the other end of which is equipped with a No. 2 output electrode. A connector is provided on the side wall of the isolation plate, which is electrically connected to the wire harness. Several nickel plates are connected to the end of the wire harness, and the nickel plates are soldered to the surface mount fuse by soldering.

[0007] Preferably, the connector is connected to the wire harness by crimping.

[0008] Preferably, all wires on the wire bundle are connected to the nickel sheet by crimping.

[0009] Preferably, a number of connecting aluminum bars are mounted on the top of the wire bundle.

[0010] Preferably, the nickel sheet is connected to the first output electrode, the second output electrode, and the connecting aluminum bar by laser welding.

[0011] Preferably, the first output electrode, the second output electrode, and the connecting aluminum bar are connected to the aluminum terminal NTC by ultrasonic welding.

[0012] Preferably, the first output pole, the second output pole, and the connecting aluminum bar are fastened together by clips and isolation plates.

[0013] Preferably, the surface mount fuse is soldered onto a nickel sheet.

[0014] Compared with the prior art, the present invention has the following advantages: 1) Soldering nickel sheets and surface mount fuses with tin simplifies the design, optimizes the process, and reduces production costs; 2) The nickel plate, output electrode, and connecting aluminum bar are connected by laser welding for voltage sampling. The fuse welded on the nickel plate cuts off the circuit in the event of a large current to prevent damage to the components in the circuit. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 The diagram illustrates a CCS (Continuous Charge System) structure for a battery harness with an integrated fuse. It includes an isolation plate 6, with a first output terminal 2 mounted at one end and a second output terminal 8 mounted at the other end. A connector 1 is located on the side wall of the isolation plate 6, electrically connected to a wire harness 3. Several nickel plates 5 are connected to the end of the wire harness 3, and these nickel plates 5 are soldered to surface-mount fuses 4. The surface-mount fuses 4 are soldered onto the nickel plates. Figure 5 As shown.

[0023] This design allows for the selection of different aluminum busbars and soldering methods depending on the sampling location (requirement) on the battery cell. The specific connection methods are as follows: Preferably, connector 1 is connected to wire harness 3 by crimping. All wires on wire harness 3 are connected to nickel plates 5 by crimping. Several connecting aluminum bars 9 are mounted on top of wire harness 3.

[0024] Nickel sheet 5 is connected to output electrode 2, output electrode 8, and connecting aluminum bar 9 via laser welding. Output electrode 2, output electrode 8, and connecting aluminum bar 9 are connected to aluminum terminal NTC7 via ultrasonic welding. Output electrode 2, output electrode 8, and connecting aluminum bar 9 are securely connected via clips and isolation plate 6.

[0025] The wires and nickel plates are connected by crimping. The aluminum terminal NTC, output pole 1, output pole 2, and connecting aluminum bar are connected by ultrasonic welding for temperature sampling. The nickel plates, output pole 1, output pole 2, and connecting aluminum bar are connected by laser welding for voltage sampling. The surface-mount fuse soldered onto the nickel plate can cut off the circuit in the event of a large current, preventing damage to the components in the circuit. Output terminals one and two, the connecting aluminum bar, and the isolation plate are fixedly connected by clips to meet the required spacing between the battery cells, facilitating subsequent cell soldering and temperature sampling. The wires and connectors are connected via terminal crimping, together forming a CCS sampling system that integrates voltage and temperature sampling.

[0026] In use, when the current exceeds the rated value of the fuse, the fusible link inside the fuse will melt due to overheating, thereby cutting off the circuit and preventing damage to the components in the circuit. In the event of a short circuit, the current will increase sharply, and the fuse will quickly melt, protecting the power supply and equipment and preventing more serious damage.

[0027] The purpose of this utility model is to provide a CCS structure for energy storage battery harnesses with integrated fuses. By setting up a patch fuse, the fuse can effectively prevent overheating and battery thermal runaway caused by overcurrent by cutting off abnormal current, thereby improving fire safety. This design simplifies the design, optimizes the process, and reduces production costs by using an integrated nickel sheet and patch fuse.

[0028] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
