Description

[Technical field]

[0001] The present invention relates to a secondary battery ID confirmation system and a secondary battery ID confirmation method. [Background technology]

[0002] A secondary battery is a battery that can be charged and discharged, unlike a primary battery that cannot be charged. Low-capacity secondary batteries are used in small portable electronic devices such as smartphones, feature phones, laptop computers, digital cameras, and camcorders, while large-capacity secondary batteries are widely used as motor drive power sources and power storage batteries in hybrid vehicles, electric vehicles, and the like. Such secondary batteries include an electrode assembly consisting of a positive electrode and a negative electrode, a case that houses the electrode assembly, and an electrode terminal connected to the electrode assembly.

[0003] A unique ID may be set for each of the secondary batteries, which allows systematic management of the SOC (State Of Charge) and SOH (State Of Health) for each of the secondary batteries. In addition, the unique ID may be used to determine whether the secondary battery is a certified genuine product.

[0004] Generally, the method of determining the ID set for each secondary battery involves inputting a specific signal to the secondary battery, and when a corresponding signal is output from the secondary battery, receiving the output signal to confirm the ID of the secondary battery and confirm that the secondary battery is an authenticated secondary battery.

[0005] However, such a method of verifying the ID of a secondary battery involves analyzing the ID code of the secondary battery, inputting a signal corresponding to the ID code into the secondary battery, and receiving a corresponding output signal, which may result in the secondary battery being mistaken for an authenticated secondary battery. Summary of the Invention [Problem to be solved by the invention]

[0009] The polarity arrangement of the magnet part of the secondary battery may be different for each secondary battery according to the ID.

[0010] The polarity arrangement of the magnet part of the wireless charging device may correspond to the polarity arrangement of the magnet part of the secondary battery for each secondary battery according to the ID.

[0012] The secondary battery magnet part has north and south poles arranged alternately in a concentric circle, and the wireless charging device magnet part has an south pole arranged at a position corresponding to the north pole of the secondary battery magnet part, and an north pole arranged at a position corresponding to the south pole of the secondary battery magnet part.

[0013] A method for confirming a secondary battery ID according to one embodiment of the present invention to solve the technical problems includes a step of placing a secondary battery, including a secondary battery magnet part having a polarity arrangement structure corresponding to the ID of the secondary battery, on a wireless charging device, a step of magnetically coupling the secondary battery magnet part of the secondary battery to a wireless charging device magnet part of the wireless charging device, and fixing the secondary battery to the wireless charging device, and a step of confirming whether the secondary battery has been charged, and if the secondary battery is charged, a step of determining that the ID of the secondary battery has been confirmed.

[0028] Hereinafter, a secondary battery ID confirmation system according to an embodiment of the present invention will be described with reference to FIGS.

[0029] Fig. 1 is a diagram showing the inter-relationship of components of a secondary battery ID confirmation system according to an embodiment of the present invention. Fig. 2 is a diagram showing the position of a secondary battery according to an embodiment of the present invention when placed on a wireless charging device. Fig. 3 is a diagram showing how the N pole and S pole of a secondary battery magnet part of a secondary battery and a wireless charging device magnet part of a wireless charging device are arranged so that they attract each other. Fig. 4 is a diagram showing how the N pole and S pole of a secondary battery magnet part of a secondary battery and a wireless charging device magnet part of a wireless charging device are arranged so that they do not correspond to each other.

[0030] 1 to 4, a secondary battery ID verification system according to one embodiment of the present invention includes a secondary battery 1 including a secondary battery magnet part M1 and a wireless charging device 10 including a wireless charging device magnet part M10 for charging the secondary battery 1.

[0031] The wireless charging device magnet part M10 includes a polarity arrangement that corresponds to the secondary battery magnet part M1 so that an attractive force acts therebetween, and the secondary battery magnet part M1 is placed in a position corresponding to the wireless charging device magnet part M10 and includes an ID confirmation part 2 that determines that the ID of the secondary battery 1 has been confirmed when the secondary battery 1 is charged.

[0032] The secondary battery 1 can be charged via a wireless charging device 10. When the secondary battery 1 is placed on the wireless charging device 10, it can be remotely charged by electromagnetic induction caused by a wireless charging device coil CO10 formed in the wireless charging device 10.

[0033] In this case, if the secondary battery coil CO1 formed on the secondary battery 1 is arranged to correspond to the wireless charging device coil CO10 of the wireless charging device 10, the secondary battery 1 can be charged via the wireless charging device 10. That is, according to this embodiment, the secondary battery 1 can be charged via the wireless charging device 10 only if the secondary battery 1 is accurately arranged in a position corresponding to the wireless charging device 10. On the other hand, if the secondary battery 1 is not arranged in a position corresponding to the wireless charging device 10 and is shifted or crooked from the wireless charging device 10, the secondary battery coil CO1 is not arranged to correspond to the wireless charging device coil CO10, and the secondary battery 1 is not charged.

[0034] In order for the secondary battery 1 to be accurately placed in a corresponding position on the wireless charging device 10, the secondary battery magnet part M1 formed on the secondary battery 1 needs to be accurately placed in a corresponding position with the wireless charging device magnet part M10 formed on the wireless charging device 10. According to this embodiment, the secondary battery magnet part M1 is placed in a corresponding position with the wireless charging device magnet part M10, whereby the charging operation of the secondary battery 1 can be performed.

[0035] In addition, the battery charger may include an ID confirmation unit 2 that determines that the ID of the secondary battery 1 has been confirmed when the secondary battery 1 is charged via the wireless charging device 10. When the secondary battery 1 is placed on the wireless charging device 10, the ID confirmation unit 2 may confirm whether the secondary battery 1 has been charged via the wireless charging device 10. In this case, when the secondary battery 1 is charged via the wireless charging device 10, the ID confirmation unit 2 determines that the ID of the secondary battery 1 has been confirmed.

[0036] More specifically, according to the present embodiment, the polarity arrangement of the secondary battery magnet part M1 may be different for each secondary battery according to the unique ID included in each secondary battery. That is, the polarity arrangement of the secondary battery magnet part M1 may be formed to have a unique polarity arrangement corresponding to the unique ID included in each secondary battery.

[0037] Also, the polarity arrangement of the magnet part M10 of the wireless charging device may correspond to the polarity arrangement of the secondary battery magnet part M10 for each secondary battery. That is, the polarity arrangement of the magnet part M10 of the wireless charging device may be formed to have a unique polarity arrangement corresponding to the unique ID included in each secondary battery. And, the polarity arrangement of the magnet part M10 of the wireless charging device having the unique polarity arrangement may correspond to the polarity arrangement of the corresponding secondary battery magnet part M1 so that mutual attraction occurs.

[0038] Therefore, when the secondary battery 1 is charged via the wireless charging device 10, the ID confirmation unit 2 can view this as a case where the polarity arrangement of the secondary battery magnet part M1 corresponding to the unique ID of the secondary battery 1 corresponds to the polarity arrangement of the wireless charging device magnet part M10, and therefore, if charging is proceeding successfully, it determines that the unique ID of the secondary battery 1 has also been confirmed along with charging.

[0039] However, if the polarities of the secondary battery magnet part and the wireless charging device magnet part are arranged so that they do not correspond to each other, as shown in FIG. 4, or if the polarities of the secondary battery magnet part and the wireless charging device magnet part are arranged so that a repulsive force acts on each other, as shown in FIG. 5, the secondary battery 1 will not be placed accurately in the corresponding position of the wireless charging device 10, and the secondary battery 1 will not be charged by the wireless charging device 10.

[0040] In this case, the ID verification unit 2 can verify that the secondary battery 1' is not being charged and determine that the unique ID of the secondary battery 1' has not been verified. In this case, the secondary battery 1' can be determined to be an unauthenticated secondary battery 1'.

[0041] The ID confirmation unit 2 may be implemented as a server in a separate computer connected via a communication network to the secondary battery 1 and the wireless charging device 10. The ID confirmation unit 2 receives a signal related to the progress of charging from the secondary battery 1 or the wireless charging device 10, and may determine whether the secondary battery 1 is being charged and whether the ID of the secondary battery 1 is being confirmed based on the signal information.

[0042] In this way, magnets having opposite polarities are attached to the wireless charging device 10 and the secondary battery 1, and when the secondary battery 1 is placed on the wireless charging device 10, if the secondary battery 1 is placed in a location other than its intended placement position, the magnetic force generated by the magnet of the wireless charging device 10 is used to push out the secondary battery 1, thereby positioning the secondary battery 1 in a specified position on the wireless charging device 10, thereby improving wireless charging efficiency.

[0043] In addition, if an unauthenticated secondary battery 1' is placed in a chargeable position on the wireless charging device 10, the wireless charging device 10 can use magnetic force to push the secondary battery 1' out of the charging position of the wireless charging device 10, thereby preventing the secondary battery 1' from being charged.

[0044] Hereinafter, a secondary battery ID confirmation system according to an embodiment of the present invention will be described with reference to Fig. 5. For the contents not shown in Fig. 5, please refer to the contents shown in Figs. 1 to 4 and the description thereof.

[0045] FIG. 5 is a diagram showing a state in which N poles and S poles are arranged to exert repulsive forces on a secondary battery magnet part of a secondary battery and a wireless charging device magnet part of a wireless charging device according to an embodiment of the present invention.

[0046] Referring to FIG. 5, in a secondary battery 1 according to one embodiment of the present invention, the secondary battery magnet part M1 has N poles and S poles arranged alternately, and the wireless charging device magnet part M10 has an S pole arranged at a position corresponding to the N pole of the secondary battery magnet part M1, and an N pole arranged at a position corresponding to the S pole of the secondary battery magnet part M1.

[0047] In other words, the secondary battery magnet part M1 has a structure in which the north poles and south poles are arranged alternately, so that even if there is a slight error in the secondary battery magnet part M1 from its corresponding position based on the wireless charging device magnet part M10, the wireless charging device magnet part M10 can move the secondary battery magnet part M1 to its magnetic force through the alternating polarity arrangement structure, thereby positioning the secondary battery magnet part M1 at its predetermined position.

[0048] Hereinafter, a secondary battery ID confirmation system according to another embodiment of the present invention will be described with reference to Fig. 6. For the contents not shown in Fig. 6, please refer to the contents shown in Figs. 1 to 4 and the description thereof.

[0049] FIG. 6 is a diagram showing the arrangement of N and S poles of a magnet part of a secondary battery and a magnet part of a wireless charging device according to another embodiment of the present invention.

[0050] 6, the secondary battery magnet part M11' may have N poles and S poles arranged alternately in a concentric circle. In this case, the wireless charging device magnet part M101' may have an S pole arranged at a position corresponding to the N pole of the secondary battery magnet part M11', and an N pole arranged at a position corresponding to the S pole of the secondary battery magnet part M11'.

[0051] In other words, the secondary battery magnet part M11' has a structure in which the north pole and the south pole are alternately arranged in a concentric circle, so that even if there is a slight error in the secondary battery magnet part M11' from its corresponding position based on the wireless charging device magnet part M101', the alternating polarity arrangement structure allows the wireless charging device magnet part M101' to move the secondary battery magnet part M11' using magnetic force, thereby positioning the secondary battery magnet part M11' in a predetermined position.

[0052] Hereinafter, a method for checking an ID of a secondary battery according to an embodiment of the present invention will be described with reference to Fig. 7. For the contents not shown in Fig. 7, please refer to the contents shown in Figs. 1 to 6 and the description thereof.

[0053] FIG. 7 is a flowchart illustrating a method for checking the ID of a secondary battery according to an embodiment of the present invention.

[0054] 7, the method for checking the ID of a secondary battery according to an embodiment of the present invention includes a step (S100) of placing a secondary battery 1 including a secondary battery magnet part M1 having a polarity arrangement structure corresponding to the ID of the secondary battery 1 on a wireless charging device 10, a step (S200) of magnetically coupling the secondary battery magnet part M1 of the secondary battery 1 to a wireless charging device magnet part M10 of the wireless charging device 10 to fix the secondary battery 1 to the wireless charging device 10, and a step (S300) of checking whether the secondary battery 1 is charged. In this case, if the secondary battery 1 is charged, a step (S400) of determining that the ID of the secondary battery 1 has been confirmed is included. Also, if the secondary battery 1 is not charged, a step (S500) of determining that the ID of the secondary battery 1 has not been confirmed is included.

[0055] This has the advantage that the ID of the secondary battery can be easily and accurately confirmed depending on whether the secondary battery is charged via a wireless charging device, and the ID of the secondary battery can also be confirmed during the process of charging the secondary battery via a wireless charging device.

[0056] Although the present invention has been described above using limited examples and drawings, it goes without saying that the present invention is not limited thereto, and various modifications and variations can be made by a person having ordinary knowledge in the technical field to which the present invention belongs within the technical spirit of the present invention and the equivalent scope of the claims.
