[0031] The battery pack is an important energy storage system in the power grid, which is generally formed by multiple batteries connected in series. When a battery in the battery pack fails, it is likely to cause many problems in the energy storage system, such as decreased capacity, increased internal resistance, abnormal output voltage, etc., which will affect the stability of the energy storage system's power supply to the outside world. Therefore, it is necessary to separate the faulty battery from the battery pack and connect a new backup battery to the battery pack so that the energy storage system can work normally.

[0032] Currently, the most common method for replacing batteries is to shut down the entire energy storage system for inspection and maintenance, leaving the battery pack open to facilitate battery replacement. However, this method will have a lot of impact on the entire power system, and the cost of a power outage inspection is extremely high.

[0033] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 1 It is a structural schematic diagram of the battery jumper device provided in this application. Figure 2 It is a structural schematic diagram of the battery jumper device provided in this application connected to the battery pack. Figure 3 It is a schematic diagram of the internal circuit structure of the battery jumper device provided in this application. Figure 4 2 is another schematic diagram of the structure of the battery jumper device provided by the present application. The present application provides a battery jumper device 1, which may include an insulating housing 2 and a one-way jumper circuit 3.

[0035] The unidirectional jumper circuit 3 may include a first input terminal 31, a first output terminal 32, a unidirectional module 33 and an isolation module 34. The unidirectional module 33 and the isolation module 34 are connected in parallel, and the first input terminal 31 and the first output terminal 32 are respectively connected to the two ends of the unidirectional module 33 and the isolation module 34. In addition, the unidirectional module 33 and the isolation module 34 are wrapped in the insulating housing 2, and the first input terminal 31 and the first output terminal 32 are at least partially exposed outside the insulating housing 2.

[0036] The first input terminal 31 and the first output terminal 32 exposed outside the insulating housing 2 can be used to connect two ends of the faulty battery 5. When the isolation module 34 is turned on, the faulty battery 5 can be short-circuited from the battery pack 6.

[0037] Through the structure provided in this embodiment, the first input terminal 31 and the second input terminal 51 of the one-way jumper circuit 3 can be used to connect the two ends of the faulty battery 5, and while the circuit in the battery pack 6 is turned on, the faulty battery 5 is isolated from the entire battery pack 6 by using the isolation module 34, thereby achieving the purpose of safely replacing the faulty battery 5. In addition, the one-way module 33 in the one-way jumper circuit 3 can be used to determine the current direction at the faulty battery 5, and can play a guiding role when connecting the backup battery to the battery pack 6, reducing the probability of the backup battery being connected in reverse, and achieving the effect of improving the replacement efficiency of the faulty battery 5.

[0038] Optionally, the battery jumper device 1 may further include a tool box 4 and a shoulder strap 41. The tool box 4 can be used to store structures related to the battery jumper device 1, such as an insulating wrench, an insulating screwdriver, a shorting line, etc., so as to face a comprehensive range of usage scenarios and improve the usability of the battery jumper device 1. The shoulder strap 41 can facilitate the user to carry the battery jumper device 1, so as to improve the portability of the battery jumper device 1.

[0039] The insulating wrench can be used to tighten or loosen bolts or nuts on the battery. The insulating design can prevent the operator from getting an electric shock during work. When it is necessary to connect or remove the battery or the battery jumper device 1, this tool can provide the necessary torque so that the user can use the battery jumper device 1.

[0040] The insulated screwdriver is used to tighten or loosen screws with a cross slot. It also has insulation properties to protect the user's safety. This tool can be useful when the battery cover or certain parts need to be fixed with screws during the connection or removal of the battery.

[0041] Shorting wires are mainly used to temporarily short circuits in specific situations. For example, during certain operations, it may be necessary to short circuit a circuit to ensure safety or for troubleshooting. Shorting wires can play a role when it is necessary to ensure that a certain part of the circuit is shorted to prevent accidental discharge or for circuit testing.

[0042] In an embodiment of the present application, the unidirectional module 33 may include a first switch 331 and a diode 332, the first switch 331 and the diode 332 are connected in series, and the isolation module 34 includes a second switch 341. Thus, the unidirectional conduction property of the diode 332 is used to determine the current direction at both ends of the faulty battery 5, and after the second switch 341 is turned on, the structure of the isolation module 34 equivalent to the wire 371 can be used to cross the faulty battery 5 to connect the third input terminal 61 with the third output terminal 62, thereby short-circuiting the faulty battery 5 from the battery pack 6, so that the user can remove the faulty battery 5 more safely.

[0043] In one embodiment of the present application, the insulating housing 2 may be provided with an observation hole 21. The circuit body may further include a detection module 35, which is connected to the one-way module 33. The detection module 35 is used to detect whether the one-way module 33 is connected and can feedback the result of the detection. The detection module 35 may be at least partially exposed through the observation hole 21, so as to feedback the detection result to the user of the battery jumper device 1.

[0044] Optionally, see Figure 8 , Figure 8 2 is a fourth structural diagram of the unidirectional jumper circuit provided by the present application. The diode 332 may be a light emitting diode 333, and the light emitting diode 333 may include a connecting portion and a light emitting portion, and the light emitting portion is at least partially exposed through the observation hole 21. When the connecting portion of the light emitting diode 333 in the unidirectional module 33 is connected to the battery pack 6, if the direction of the current in the circuit of the battery pack 6 is the same as the direction of the light emitting diode 333, the unidirectional module 33 is forwardly conductive at this time, and the light emitting portion of the light emitting diode 333 will emit light under the action of the current.

[0045] The light emitted by the light emitting part can be transmitted to the outside through the observation hole 21, so that the user can judge the current direction in the battery pack 6 according to whether the light emitting part is emitting light, so as to play a guiding role when connecting the backup battery 7 and reduce the probability of reverse connection.

[0046] In one embodiment of the present application, the detection module 35 includes a light emitting element 351 and / or an ammeter 352, and the first input terminal 31, the one-way module 33, the light emitting element 351 and / or the ammeter 352, and the first output terminal 32 are connected in series in sequence. Thus, the light emitting element 351 and / or the ammeter 352 are used to determine the current direction at both ends of the faulty battery 5.

[0047] See also Figure 6 , Figure 6 This is a second structural schematic diagram of the unidirectional jumper circuit provided in this application. Figure 6In the illustrated embodiment, the detection module 35 includes an ammeter 352, which is connected in series with the unidirectional module 33. When the diode 332 is turned on, the ammeter 352 can measure the current of the branch where the unidirectional module 33 is located, and when the diode 332 is not turned on, the ammeter 352 has no indication, so that the current direction of the two ends of the faulty battery 5 can be determined.

[0048] See also Figure 7 , Figure 7 This is a third structural schematic diagram of the unidirectional jumper circuit provided by the present application. Figure 7 In the illustrated embodiment, the detection module 35 includes a light emitting member 351, which is connected in series with the one-way module 33. When the diode 332 is turned on, the light emitting member 351 can emit light and be exposed through the observation hole 21, and when the diode 332 is not turned on, the light emitting member 351 does not emit light, so that the current direction at both ends of the faulty battery 5 can be determined according to the state of the light emitting member 351.

[0049] Optionally, see Figure 5 , Figure 5 The detection module 35 may include a voltmeter 353 , which is connected in parallel with the unidirectional module 33 , so as to detect the voltage at the unidirectional module 33 .

[0050] Among them, the light-emitting component 351, the ammeter 352, and the voltmeter 353 can be at least partially exposed through the observation hole 21, so that the user can obtain the detection results fed back by the light-emitting component 351, the ammeter 352, and the voltmeter 353, and then judge the operating status of the faulty battery 5 and the battery pack 6 according to the detection results.

[0051] Optionally, see Figure 4 and Fig.10 , Fig.10 3 is a fifth structural diagram of the unidirectional jumper circuit provided by the present application. The battery jumper device 1 may further include a first detection terminal 38, which may be connected between the diode 332 and the first switch 331, and connected to the detection module 35. For the first detection terminal 38 and the first output terminal 32, the branch where the diode 332 is located does not have the first switch 331, so the on-off of the branch is only affected by the conduction direction of the diode 332.

[0052] Before connecting the first input terminal 31 with the third output terminal 62, the user can connect the first output terminal 32 with the third input terminal 61 and the first detection terminal 38 with the second output terminal 52, so as to conveniently detect the operating status of the faulty battery 5 and the battery pack 6 without the risk of short circuit, open circuit, etc.

[0053] Optionally, the detection module 35 may be a detection chip, which can detect multiple data of the faulty battery 5 when the detection chip is connected to the faulty battery 5 and the battery pack 6, so that the user can analyze the fault condition of the faulty battery 5 by integrating the multiple data.

[0054] Furthermore, the detection chip may include a communication module, so that the measured multiple data can be sent to a server or a user's client through wired and / or wireless communication methods, so that the user can fully understand the situation of the faulty battery 5.

[0055] Optionally, the detection chip can use the server to record information such as the location, model, fault condition, fault cause, fault time, replacement time, model of the backup battery 7 of the faulty battery 5 in the battery pack 6 to improve the availability of the battery jumper device 1.

[0056] Optionally, the detection chip may include an identification module to identify the nameplate of the faulty battery 5 to obtain normal parameters of the faulty battery 5, and then compare the normal parameters with the current parameters actually measured by the detection module 35 for user reference.

[0057] Optionally, the detection chip can further determine the fault type and severity of the faulty battery 5 based on the comparison result, so as to provide it to users who do not understand the relevant technology and find it difficult to understand the data, thereby lowering the threshold for using the battery jumper device 1 and improving the availability of the battery jumper device 1.

[0058] Optionally, since not all faulty batteries 5 can be isolated from the battery pack 6 by short-circuiting, for example, a battery that is faulty but can still output current, the detection chip can also determine whether it is safe to isolate the faulty battery 5 from the battery pack 6 by short-circuiting according to the comparison result, so that the user can select an appropriate method to replace the faulty battery 5.

[0059] In an embodiment of the present application, the first switch 331 and / or the second switch 341 may be a protection switch. When the current passing through the first switch 331 and / or the second switch 341 is too large, the first switch 331 and / or the second switch 341 may be automatically disconnected to protect the battery pack 6, the faulty battery 5 and the battery jumper device 1, reduce the probability of danger during the replacement of the faulty battery 5, and provide certain protection for the staff who replace the faulty battery 5.

[0060] Alternatively, if Figure 3As shown, the unidirectional jumper circuit 3 may further include an overload protection module 36, which is connected in series with the unidirectional module 33 and the isolation module 34. The overload protection module 36 is used to detect the current passing through the unidirectional jumper circuit 3. When the current exceeds a first threshold, the overload protection module 36 is disconnected. This protects the battery pack 6, the faulty battery 5, and the battery jumper device 1, reduces the probability of danger during the replacement of the faulty battery 5, and provides certain protection for the staff who replace the faulty battery 5.

[0061] In one embodiment of the present application, refer to Figure 4 The insulating housing 2 may include a first triggering region 22 and a second triggering region 23 . The first triggering region 22 drives and connects the first switch 331 , and the second triggering region 23 drives and connects the second switch 341 .

[0062] The first trigger area 22 and the second trigger area 23 can be set on the side surface of the insulating shell 2 away from the circuit body. The user can effectively control the on and off of the first switch 331 and the second switch 341 by operating the first trigger area 22 and the second trigger area 23 on the outer surface of the insulating shell 2. Due to the existence of the insulating shell 2, the risk of electric shock faced by the user when controlling the first switch 331 and the second switch 341 can be reduced.

[0063] In one embodiment of the present application, the insulating housing 2 may include a plate 24 and a plurality of supporting ribs 25, wherein the plurality of supporting ribs 25 are cross-arranged on the housing surface. The plate 24 of the insulating housing 2 may be set to be relatively thin, and the cross-arranged supporting ribs 25 may be increased to maintain the mechanical strength of the insulating housing 2, thereby reducing the weight of the battery jumper device 1, reducing the material used in the battery jumper device 1, and reducing the volume of the battery jumper device 1, while reducing the probability of damage to the insulating housing 2, and improving the portability of the battery jumper device 1.

[0064] See also Fig. 9 , Fig. 9 3 is a schematic diagram of the structure of the clamp provided by the present application. In one embodiment of the present application, the battery jumper device 1 further includes two connectors 37, one end of one connector 37 is connected to the first input terminal 31, and one end of the other connector 37 is connected to the first output terminal 32. The other end of the connector 37 connected to the first input terminal 31 is used to connect to the third output terminal 62 of the battery pack 6, and the other end of the connector 37 connected to the first output terminal 32 is used to connect to the third input terminal 61 of the battery pack 6.

[0065] The third output terminal 62 is used to connect to the second input terminal 51 of the faulty battery 5, and the third input terminal 61 is used to connect to the second output terminal 52 of the faulty battery 5. Thus, the battery jumper device 1 is connected to the system including the battery pack 6 and the faulty battery 5.

[0066] For the battery jumper device 1 having the first detection terminal 38 , the connector 37 can also be used to connect the first detection terminal 38 and the battery pack 6 to detect the faulty battery 5 .

[0067] Optionally, the connector 37 connecting the first detection terminal 38, the first input terminal 31, and the first output terminal 32 can be provided with different colors and appearances, respectively, so as to facilitate user identification. For example, the connector 37 connecting the first input terminal 31 is black, the connector 37 connecting the first output terminal 32 is red, and the connector 37 connecting the first detection terminal 38 is green.

[0068] In one embodiment of the present application, the connecting member 37 may include a wire 371 and a clamping member 372, and the clamping member 372 is disposed at one end of the wire 371 away from the first input terminal 31 or the first output terminal 32. Each clamping member 372 may include two clamping portions 373 and two pressing portions 376, and a clamping opening 374 is formed between the two clamping portions 373 of the same clamping member 372. When the two pressing portions 376 of the same clamping member 372 move toward each other, the clamping opening 374 opens, and vice versa.

[0069] Among them, multiple groups of clamping grooves 375 can be provided along the clamping opening 374, and each group of clamping grooves 375 is used to clamp and fix different types of third input terminals 61 or third output terminals 62, so that the battery jumper device 1 can adapt to different types of faulty batteries 5 and battery packs 6, thereby improving the versatility of the battery jumper device 1.

[0070] The embodiment of the present application also provides a method for replacing a faulty battery 5 based on a battery jumper device 1. The battery jumper device 1 may include an insulating shell 2 and a one-way jumper circuit 3. The one-way jumper circuit 3 may include a first input terminal 31, a first output terminal 32, a one-way module 33, and an isolation module 34. The one-way module 33 is connected in parallel with the isolation module 34, and the first input terminal 31 and the first output terminal 32 are connected to the two ends of the one-way module 33 and the isolation module 34, respectively. In addition, the one-way module 33 and the isolation module 34 are wrapped in the insulating shell 2, and the first input terminal 31 and the first output terminal 32 are at least partially exposed outside the insulating shell 2.

[0072] In the first step, the one-way module 33 is turned on and the isolation module 34 is kept turned off.

[0073] In the second step, the first input terminal 31 is connected to the third output terminal 62 of the battery pack 6, and the first output terminal 32 is connected to the third input terminal 61 of the battery pack 6. The third output terminal 62 is connected to the second input terminal 51 of the faulty battery 5, and the third input terminal 61 is connected to the second output terminal 52 of the faulty battery 5. Thus, the unidirectional module 33 can be used to detect the current direction at both ends of the faulty battery 5.

[0074] In the third step, in response to the unidirectional module 33 being normally turned on, the isolation module 34 is turned on.

[0075] In the fourth step, the connection between the third output terminal 62 and the second input terminal 51, and the connection between the third input terminal 61 and the second output terminal 52 are disconnected, so as to remove the faulty battery 5 from the battery pack 6. At this time, the battery jumper device 1 can use the unidirectional jumper circuit 3 therein to continuously maintain the connection of the circuit in the battery pack 6, so as to avoid the battery pack 6 being disconnected and causing adverse effects on the entire energy storage system.

[0076] In the fifth step, the isolation module 34 is disconnected, and then the fourth input terminal 71 of the backup battery 7 is connected to the third output terminal 62, and the fourth output terminal 72 of the backup battery 7 is connected to the third input terminal 61. The installation direction of the backup battery 7 can be determined according to the situation of the one-way module 33, and since the backup battery 7 functions normally, once the isolation module 34 short-circuits it, it may cause serious heat, electric sparks and other dangerous situations. Disconnecting the isolation module 34 before connecting the backup battery 7 can reduce the risk of short-circuiting the backup battery 7 and improve the safety of the method for replacing the faulty battery 5.

[0077] In the sixth step, the connection between the first output terminal 32 and the third input terminal 61 and the connection between the first input terminal 31 and the third output terminal 62 are disconnected, thereby removing the battery jumper device 1 from the battery pack 6, so that the battery pack 6 replaced with the backup battery 7 can be restored to a normal operating state, and the replacement process of the faulty battery 5 is ended.

[0078] Through the method provided in this embodiment, the first input terminal 31 and the second input terminal 51 of the one-way jumper circuit 3 can be used to connect the two ends of the faulty battery 5, and while the circuit in the battery pack 6 is turned on, the isolation module 34 is used to isolate the faulty battery 5 from the entire battery pack 6, thereby achieving the purpose of safely replacing the faulty battery 5. In addition, the one-way module 33 in the one-way jumper circuit 3 can be used to determine the current direction at the faulty battery 5, and can play a guiding role when connecting the backup battery to the battery pack 6, reducing the probability of the backup battery being connected in reverse, and achieving the effect of improving the replacement efficiency of the faulty battery 5.
