[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The device shown is an on-site repair device for battery voltage imbalance in an energy storage system, including a repair device body 1 and an adapter plate 4 installed on the rear side of the repair device body 1.

[0026] The front outer wall of the adapter plate 4 is fixedly connected with multiple slots a11 and b12 at equal intervals;

[0027] A connecting line 5 is provided between the card slot a11 and the main body 1 of the repair device;

[0028] Multiple data acquisition lines 18 are located on the right side of the multiple card slots b12. During on-site repair, staff only need to plug the PACK acquisition terminals of the product to be balanced into the corresponding slots on the adapter plate 4. Once the connection is successful, the voltage data of each individual battery is transmitted to the repair device via the acquisition lines 18. The multiple card slots b12 of the adapter plate 4 ensure that multiple batteries can be monitored independently at the same time. The battery equalizer receives data from the acquisition lines 18 in real time, monitors and analyzes the voltage of each individual battery, and can identify voltage imbalances between batteries by comparing the voltages of each battery. Once a voltage imbalance is detected, the battery equalizer will send a signal command to control the equalization circuit or device on the equalization adapter plate 4 to actively discharge the battery with the higher voltage or transfer the charge to the battery with the lower voltage.

[0029] Multiple magnetic blocks 16 are evenly spaced at the four corners of the rear outer wall of the adapter plate 4 to magnetically fix the adapter plate 4 to the battery storage frame. When it is necessary to restrict the position of the adapter plate 4, the side with the magnetic block 16 is aligned with the battery mounting bracket, and the installation position of the adapter plate 4 can be restricted by magnetic attraction between the magnetic block 16 and the mounting bracket.

[0030] like Figure 3 As shown, baffles 13 are fixedly connected to the four corners of the rear outer wall of the adapter plate 4 to restrict the installation position of the magnetic block 16. Sponges 14 are provided at the four corners of the adapter plate 4. Each of the multiple sponges 14 has an opening 15 inside. The magnetic block 16 and the baffles 13 are fixedly connected by adhesive.

[0031] The mounting position of the magnetic block 16 is provided by the baffle 13, and the connection is made by adhesive, which makes it easier and faster to fix the mounting position of the magnetic block 16. When the adapter plate 4 needs to be attached to the mounting bracket for fixing the battery, the sponge 14 will shrink, exposing the magnetic block 16 for magnetic attraction. When the adapter plate 4 is removed, the sponge 14 will reset and cover the magnetic block 16.

[0032] like Figure 1 and Figure 4 As shown, a storage box 6 is fixedly connected to the lower outer wall of the main body 1 of the repair device. A drawer 17 is provided inside the storage box 6 to store miscellaneous items. A cover plate 7 is fixedly connected to the front outer wall of the drawer 17. A handle b8 is embedded in the front outer wall of the cover plate 7. A sliding groove is provided inside the storage box 6 to restrict the position of the drawer 17. The drawer 17 can slide back and forth inside the storage box 6.

[0033] When a user needs to store or retrieve items from drawer 17, they can easily pull out the cover 7 by pulling out the handle b8, which will also pull out the drawer 17. Then, they can retrieve or place items inside the drawer 17. This process is simple and quick, which helps to manage and store tools efficiently.

[0034] like Figure 1 and Figure 2 As shown, a display screen 2 is embedded in the inner side of the front outer wall of the main body 1 of the repair device, and a control screen 9 is provided on the lower side of the display screen 2. A handle a3 is fixedly connected to the upper outer wall of the main body 1 of the repair device, and pins 10 are provided inside the multiple slots a11 and slots b12.

[0035] The operator moves the device by handle a3 and inserts the acquisition end of the battery to be equalized directly into the corresponding slots a11 and b12. At this time, pin 10 provides the necessary electrical connection. The display screen 2 updates the status information of all batteries in real time. The user can select different operating modes or start equalization processing through the control screen 9.

[0036] The implementation principle of this embodiment is as follows: During on-site repair, the staff only needs to plug the PACK acquisition terminal of the product to be balanced into the corresponding slot on the adapter plate 4. Once the connection is successful, the voltage data of each individual battery is transmitted to the repair device through the acquisition line 18. The multiple slots b12 of the adapter plate 4 ensure that multiple batteries can be monitored independently at the same time. The battery equalizer receives the data from the acquisition line 18 in real time, monitors and analyzes the voltage of each individual battery, and can identify the voltage imbalance between batteries by comparing the voltage of each battery. Once a voltage imbalance is detected, the battery equalizer will send a signal command to control the equalization circuit or device on the equalization adapter plate 4 to actively discharge the battery with higher voltage or transfer the power to the battery with lower voltage. When it is necessary to restrict the position of the adapter plate 4, the side with the magnetic block 16 is aligned with the mounting bracket of the battery. The installation position of the adapter plate 4 can be restricted by the magnetic attraction between the magnetic block 16 and the mounting bracket.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
