Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a battery capacity sampling harness assembly. Background Technology

[0002] The manufacturing process of lithium batteries is divided into three stages: pre-processing, mid-processing, and post-processing. The pre-processing stage aims to process raw materials into electrode sheets, with coating being the core process. The mid-processing stage aims to process the electrode sheets into unactivated cells. The post-processing stage involves testing and packaging, with formation and capacity testing being the core processes. The formation, capacity testing, and testing system is the most critical link in the post-processing stage. The formation and capacity testing of lithium battery cells is achieved through charging and discharging to initially activate the active materials of the cell, which is an energy conversion process.

[0003] Currently, the wiring harness used for battery testing during the formation and capacity testing process is a single round electronic wire, which is fixed to a plastic housing by riveting terminals at both ends to form a wiring harness; the other end of the electronic wire is connected to the detection probe used by the user to form a working connection.

[0004] Problems with the existing structure:

[0005] a. The number of electronic wires for each product is determined by the number of detection probes. The production process for multi-pin wire harnesses is long and the manufacturing process is complex.

[0006] b. If any of the detection probes malfunctions, the entire wiring harness needs to be replaced. This process is time-consuming, affects detection efficiency and user experience, and is costly. Utility Model Content

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0027] Please refer to Figures 1 to 7 The composition and capacity sampling harness assembly of this utility model includes a head connector, a flat ribbon cable, an adapter, and a battery probe module.

[0028] The head connector connects to one end of the flat ribbon cable. The head connector is the port for connecting the modular, capacitive sampling harness assembly to the front end of the test equipment or data acquisition system. It integrates the signals from all channels (voltage, temperature, etc.) in the harness into one or more standard-compliant connectors (such as D-Sub, HD D-Sub, DBxx, AMP CPC, circular connectors, custom interfaces, etc.).

[0029] The adapter is compatible with flat ribbon cables for electrical connection. The battery probe module consists of an electronic wire, a detection probe, and a plug that matches the adapter. The electronic wire connects the detection probe and the plug.

[0030] The formation and capacity sampling harness assembly of this invention is a crucial bridge connecting battery cells / modules / packs with testing equipment (such as battery testers, data acquisition systems, and BMS test benches). The detection probes are the parts of the harness that directly contact the battery under test (cell terminals, module terminals, temperature sensor points, voltage sampling points, etc.). They are responsible for collecting the battery's electrical signals (voltage) or physical signals (temperature).

[0031] In one implementation, the flat ribbon cable consists of several wires, and there are multiple adapters. Each adapter is staggered and connected to different wires of the flat ribbon cable to facilitate simultaneous multi-point testing.

[0032] In one implementation, the adapter is located on a flat ribbon cable for easy and quick insertion.

[0033] In one implementation, the battery probe module has multiple sets of electronic wires and detection probes, which facilitates the simultaneous detection of multiple targets.

[0034] In one implementation, the modularized capacity sampling harness assembly also includes clips for securing the flat cabling and adapters. The clips facilitate the installation, replacement, and maintenance of the modularized capacity sampling harness assembly. The clips ensure that the harness will not break under vibration or accidental pulling, guaranteeing testing continuity and safety (especially in high-voltage applications).

[0035] In one embodiment, the fastener consists of a clamping part, a locking part, and a snap-fit ​​part. The clamping part has a cable groove corresponding to the flat ribbon cable and a slot corresponding to the adapter. Both the cable groove and the slot are open slots, facilitating the installation of the fastener onto the flat ribbon cable. The locking part is used to lock one side of the corresponding opening of the clamping part. The snap-fit ​​part is located at the bottom of the clamping part. In use, the clamping part is inserted into the corresponding adapter on the flat ribbon cable, the slots lock the two sides of the adapter, and the locking part is installed on the open side of the clamping part.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
