[0002] In fields such as power, communications, new energy vehicles, and energy storage power stations, battery packs are the core energy storage units, and their performance and health status directly determine the reliability and safety of the entire system. In order to accurately evaluate key performance indicators such as capacity, internal resistance, and cycle life of battery packs, it is necessary to use professional charge and discharge testing equipment to test and maintain them.

[0003] 1. The handles or levers of traditional equipment are usually of a fixed height or length and cannot be adjusted according to the operator's height, strength or carrying habits;

[0004] 2. The current wires connecting the test probes usually lack a dedicated storage device, and are often haphazardly twisted or bundled after use. This not only appears messy, but the tangled cables are also prone to pulling and tangling. Therefore, we propose a high-current synchronous rectification charge-discharge test device.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses a high-current synchronous rectification charge-discharge testing device, comprising a tester body 1 and a detection probe assembly 6. A control panel 2 is mounted on the front surface of the tester body 1, and a charging socket 3 is provided on the front surface of the control panel 2. The charging socket 3 on the front surface allows the operator to clearly observe the interface alignment during connection, ensuring precise connection between the plug and the socket and avoiding interface damage or poor contact caused by blind operation. Adjustable lifting components 4 are fixed on both side walls of the tester body 1, allowing the operator to adjust the lifting height according to their needs, making carrying and operation more convenient and comfortable, and effectively improving the portability and practicality of the device. A protective sleeve 5 is installed on the upper end of the tester body 1, and the detection probe assembly 6 is installed inside the protective sleeve 5. The protective sleeve 5 is made of high-strength, wear-resistant material, which not only provides reliable protection for the detection probe assembly 6 but also prevents it from being damaged by collision during carrying.

[0024] In Embodiment 1, the adjusting lifting assembly 4 is provided with a telescopic sleeve 41, and a synchronous rope winding motor is installed inside the telescopic sleeve 41. The two output ends of the synchronous rope winding motor are respectively connected to a first L-shaped pull rod assembly 42 and a second L-shaped pull rod assembly 43 via a lifting rope, and the first L-shaped pull rod assembly 42 and the second L-shaped pull rod assembly 43 have the same structure.

[0025] Specifically, one end of the L-shaped rod 421 on the first L-shaped pull rod assembly 42 and the second L-shaped pull rod assembly 43 is connected to the lifting rope, so that the operator can control the synchronous rope winding motor to drive the lifting rope to move, thereby realizing the synchronous retraction of the first L-shaped pull rod assembly 42 and the second L-shaped pull rod assembly 43 on the telescopic sleeve 41, meeting the adjustment needs of operators of different heights for lifting height, and further improving the convenience and comfort of using the equipment;

[0026] The first L-shaped pull rod assembly 42 is provided with an L-shaped rod 421. One end of the L-shaped rod 421 is connected to an anti-detachment component 422. The anti-detachment component 422 is installed on the fixed base 424 through a rotating component 423, and the anti-detachment component 422 is fixed to the side wall of the main body 1 of the tester by screws.

[0027] Specifically, the anti-detachment component 422 effectively prevents the L-shaped rod 421 from falling off during the lifting process, ensuring operational safety. At the same time, the rotating component 423 allows the anti-detachment component 422 to rotate flexibly to adapt to different lifting angle requirements. The fixed base 424 is fixed to the side wall of the main body 1 of the tester through a stable connection, providing reliable support for the entire first L-shaped pull rod assembly 42 and enhancing the structural stability of the equipment.

[0028] In the second embodiment, the detection probe assembly 6 is provided with a mounting base 63, and a positive detection probe 61 and a negative detection probe 62 are fixed on the upper surface of the mounting base 63, and the positive detection probe 61 and the negative detection probe 62 have the same structure.

[0029] Specifically, both the positive electrode detection probe 61 and the negative electrode detection probe 62 are made of highly conductive materials. These materials not only have excellent conductivity but also good corrosion resistance and oxidation resistance, ensuring stable detection performance during long-term use.

[0030] The negative electrode detection probe 62 is provided with a negative electrode test rod 621. The negative electrode test rod 621 is installed on the top of the insulating mounting post 624 through the connecting mounting part 622. A spare mounting part 623 is fixed on one side of the insulating mounting post 624. A winding post 626 is installed on one side wall of the insulating mounting post 624. A current wire 625 is wound on the winding post 626. One end of the current wire 625 is connected to the bottom of the negative electrode test rod 621, and the other end of the current wire 625 is connected to the top of the conductive rod 627. The bottom of the conductive rod 627 is connected to the body 1 of the tester.

[0031] Specifically, the connecting mounting part 622 ensures a reliable connection between the negative electrode test rod 621 and the insulating mounting post 624, preventing loosening or detachment during use. The spare mounting part 623 facilitates future expansion or maintenance. When additional components or connection methods need to be added, the spare mounting part 623 can be used directly. The winding post 626 solves the problem of storing the current conductor 625, neatly winding the current conductor 625 onto the winding post 626, avoiding potential safety hazards caused by messy winding of the current conductor 625. The current conductor 625 achieves current transmission through connection with the negative electrode test rod 621 and the conductive rod 627. The conductive rod 627 is connected to the main body 1 of the tester, ensuring that the current can be accurately transmitted to the tester for detection and analysis.

[0032] The spare mounting component 623 provided on the insulating mounting post 624 has the same structure as the connecting mounting component 622 and is used to install the spare test rod; the bottom of the conductive rod 627 is provided with a pluggable conductive interface, which is electrically connected to the corresponding port provided on the body 1 of the tester.

[0033] Specifically, the pluggable conductive interface makes it easier to connect and disconnect the conductive rod 627 from the main body 1 of the tester, greatly improving the efficiency and maintainability of the equipment. At the same time, the corresponding port settings also ensure the stability and accuracy of current transmission, avoiding measurement errors or equipment failures caused by poor connections. The spare mounting part 623 has the same structure as the connecting mounting part 622, and can be used interchangeably when the connecting mounting part 622 is damaged, enhancing the flexibility and adaptability of the equipment.

[0034] Working principle: During testing, the operator connects the positive detection probe 61 and the negative detection probe 62 to the device under test. The transmission path of the test current or signal originates from the device under test, flows through the test probe, and then through the current conductor 625 specially wound on the winding post 626. It then passes through the conductive rod 627 with a pluggable interface at the bottom and finally enters the main body 1 of the tester for analysis and processing. This ensures the stability and low loss of the current transmission path. The insulated mounting post 624 effectively prevents the risk of short circuit, while the orderly winding method avoids signal interference and safety hazards caused by the tangled conductors, laying a solid foundation for obtaining accurate charge and discharge performance data.
