Prior Art As mobile devices are developing more and more and the demand for such mobile devices is increasing, the demand for secondary batteries has also been increasing markedly. Among such secondary batteries is a secondary lithium battery that has high energy density and operating voltage and excellent preservation and service life characteristics, which has been widely used as a power source for various electronic products as well as mobile devices. .
Depending on the types of external devices in which the secondary batteries are used, the secondary batteries can be configured to have a detachable type structure in which the secondary batteries can be easily inserted into and removed from external devices or to have a built-in type structure in which secondary batteries are embedded in external devices. It is possible, for example, for a user to insert or remove a battery in one or a device, such as a portable computer. On the other hand, a device, such as a mobile phone, a layer 3 MPEG audio player (mp3), a tablet PC or a smart pad, requires a built-in battery pack due to its structure and capacity .
However, several species of combustible material are contained in the secondary lithium battery. Consequently, the secondary lithium battery may become heated or explode due to battery overload, excessive current in the battery or other external physical impacts. That is, the safety of the secondary lithium battery is very low. Consequently, safety elements, such as an element with a positive temperature coefficient (PTC) and a protection circuit module (PCM), to effectively control an abnormal state of the secondary lithium battery, such as battery overload. would have secondary lithium or the excessive current in the secondary lithium battery, are connected to a battery cell.
Generally, a secondary battery pack of the built-in type uses a plate-shaped battery cell, which is suitable for electrical connection, and a PCM is connected to the battery cell by means of conductive nickel plates by welding or weak soldering. That is, the nickel plates are connected to the electrode terminals of the battery cell by welding or weak soldering, a printed circuit board (PCB) is attached to one side of a double-sided adhesive tape, a protective tape is attached to the other side of the double-sided tape, and the electrode projections of the PCB and the nickel sheets are connected to each other by welding in a state in which the PCB is in close contact with the battery cell. In this way, the PCM is connected to the battery cell in the manufacture of a battery pack. It is necessary for the security elements. Including the PCM, be kept in electrical connection with the electrode terminals of the battery cell and, at the same time, be electrically isolated from other parts of the battery cell.
For this, insulating tapes are attached to several elements, including the PCM. In addition, the sealed part of the battery box, on which the battery cell is mounted, is partially folded, and the electrical tape is attached to it or a bar code is printed on it. In other words, the process is very complicated.
Since a series of insulating tapes or parts is required to achieve a secure connection, as described above, the battery pack assembly process is complicated, and the manufacturing cost increases.
In addition, when an external impact is applied to the battery pack, the PCM can be damaged or the dimensional stability can be considerably reduced due to the use of insulating tapes, which have low mechanical resistance.
Therefore, there is a great need for a technology that is able to reduce the number of elements assembled in a battery cell in order to simplify the assembly process, obtaining a stable coupling between the elements located in the battery cell and protecting it if the PCM.
In addition, there is also a great need for a battery pack that is capable of providing large capacity, while having the same size, considering the development trend of a device, whose weight and size are reduced.
Disclosure Technical problem Therefore, the present invention was manufactured to solve the above problems and other technical problems that have yet to be solved.
Specifically, it is an object of the present invention to present a secondary battery pack in which the number of parts required to manufacture the secondary battery pack is reduced, thereby simplifying the assembly process, and the structural stability of the battery pack is perfected. It is another object of the present invention to present a secondary battery pack in which the internal structure of the battery pack is altered in order to obtain the maximum capacity compared to battery packs that have the same pattern. It is another object of the present invention to present a protection circuit module (PCM), which is protected from external impacts, whose dimensional stability is high and which is arranged on the outside of a battery pack, while having a clean appearance, without folds.
Technical solution In accordance with an aspect of the present invention, the above and other objects can be achieved by presenting a secondary battery pack that includes an anode terminal and a cathode terminal of a battery cell, the anode terminal and the cathode terminal being made of a conductive element in the form of a plate, the anode terminal and the cathode terminal being electrically connected to a protection circuit module (PCM), the battery cell having the anode terminal and the cathode terminal formed at one end of it, the battery cell being provided, at the end of it, with a surplus thermally welded part, and the PCM including a printed circuit board (PCB) that has a protection circuit formed in it, the PCB being provided, on one side of it, with a connecting part with the cathodic terminal and connecting part with the anodic terminal and, on the other side of it, connecting part with the input and output terminal from the external, an external input and output terminal electrically connected to the PCB protection circuit through the connection part with the external input and output terminal of the PCB, and an electrically insulating PCM box, in which the PCB is mounted insertion way, the PCM being charged over the thermally welded surplus portion of the battery cell in a state in which the PCM is electrically connected to the battery cell.
That is, in the secondary battery pack according to the present invention, the PCM, which is configured to have a structure in which the PCB is mounted in the PCM box as an insert, is loaded onto the thermally welded excess part of the cell of battery. Compared with a conventional built-in secondary battery pack, therefore, it is possible to effectively protect the PCM and considerably reduce the number of parts, thereby considerably improving the efficiency of the manufacturing process.
In addition, in the secondary battery pack according to the present invention, the PCM is mounted in the PCM box in the manner of insertion. Compared with the conventional built-in secondary battery pack, in which a PCM is isolated with a conventional tape, it is therefore possible to considerably reduce the number of parts, thereby greatly improving the efficiency of the manufacturing process. Consequently, the manufacturing process of the secondary battery pack is easily carried out, the defect rate is relatively low and the battery pack has an aesthetically pleasing appearance without pleats on the outside of the battery pack.
In addition, the PCB is loaded onto the thermally welded surplus portion of the battery cell in the direction in which the PCB faces the upper end of the main cell body in a state in which the PCB is upright perpendicular to the cell of battery. Consequently, it is possible to shorten the thermally welded excess part of the battery cell compared to the structure in which the PCB is loaded in parallel with the thermally welded excess part of the battery cell, thus increasing the capacity per unit volume of the package. secondary battery.
Preferably, the PCM box covers the PCM to the exclusion of the external input and output terminal. Consequently, the PCM box is loaded over the thermally welded surplus part of the battery cell in order to fully cover the PCM, thus fully ensuring a stable installation and insulation.
Depending on the circumstances, a safety element can also be installed in the electrical connection region between one (the anode terminal, for example) of the battery cell electrode terminals and the PCB, in order to also ensure the safety of the package secondary battery. In this case, the security element can be mounted in the PCM box together with the PCB in the manner of insertion. The safety element is an element to interrupt the current when the temperature of the battery cell rises, thus ensuring the safety of the battery cell. For example, the safety element can be an element with a positive temperature coefficient (PTC), whose resistance increases with increasing temperature, or a fuse, which is cut with increasing temperature. However, the safety element is not limited to the PTC element or the fuse.
In a concrete example, the PCM box can be configured to have a hollow box structure, of which one end is opened in the form of a slot, through which the PCB is inserted. Consequently, the dimensional stability of the PCM box is increased and the PCB can be easily mounted on the PCM box.
In addition, since the PCM box covers the PCM to the exclusion of the external input and output terminal, it is possible to easily protect the PCM from external impacts.
In addition, since the PCB is mounted in the PCM box in the manner of insertion, it is possible to considerably reduce the time and the assembly process compared to a PCM of the type of assembly using hooks.
Preferably, an insulating tape is also attached to the region of exposure to the electrode terminals of the thermally welded surplus. Consequently, it is possible to obtain more effectively the insulation in the folded region. The electrical tape is preferably a double-sided tape. The double-sided insulation tape provides a coupling force between the PCM box and the thermally welded surplus when the PCM box is assembled, thus also improving structural stability.
In a concrete example, the PCM box can be configured to have a hollow box structure, of which one end is opened in the form of a slot, through which the PCB is inserted. Consequently, the dimensional stability of the PCM box is increased and the PCB can be easily inserted by tearing the PCM box.
Several types of battery cell can be used in the secondary battery pack according to the present invention. The battery cell used in the secondary battery pack according to the present invention can be a secondary battery in the form of a bag, which has an electrode assembly of a cathode / separator / anode structure mounted in a battery box made of a laminated sheet that includes a layer of metal and a layer of resin in a sealing state, the thickness and weight of which are small.
Preferably, the PCB is a flexible printed circuit board (PCB). Consequently, the PCB can be easily folded as needed. For reference purposes, FPCB means a printed circuit board that uses a flexible insulating board.
As defined above, the PCB, which has the protection circuit to control the overload, over-discharge, over-current, etc., of the battery, is provided, on one side of it, with the connection part with the cathodic terminal and the connection part with the anode terminal and, on the other side of it, the connection part with the external input and output terminal.
Depending on the circumstances, a security element can also be fitted between the anode terminal and / or the cathode terminal and the PCB, in order to also ensure the safety of the secondary battery pack. Preferably, the security element is positioned between the anode terminal of the battery cell and the PCB. In addition, the security element can be mounted in the PCM box together with the PCB in the manner of insertion, thus ensuring structural stability.
Consequently, it is possible to connect the battery cell cathode terminal to the connection part with the PCB cathode terminal without changing the conformation or without using additional elements and to connect one side of the security element to the connection part with the PCB security element. located on the same side of the PCM in a state in which the anode terminal of the battery cell is connected to the other side of the security element. Consequently, the safety element, whose structural strength is low, is stably mounted on the PCB, thereby reducing the rate of defects in the manufacturing process and thus improving the efficiency of the manufacturing process. The safety element is an element to interrupt the current when the temperature of the battery cell rises, thus ensuring the safety of the battery pack. For example, the safety element can be an element with a positive temperature coefficient (PTC), whose resistance increases with increasing temperature, or a fuse, which is cut with increasing temperature. However, the safety element is not limited to the PTC element or the fuse.
In one example, the external input and output terminal can be connected to one side of the PCB, and the connection part to the anode terminal and the connection part to the cathode terminal can be formed on the other side of the PCB so that the the connection part with the anode terminal and the connection part with the cathode terminal correspond to the anode terminal and the cathode terminal, respectively.
In another example, the shape of the external input and output terminal is not specifically restricted as long as the external input and output terminal can be electrically connected to the PCB in order to supply current from an external device, such as a charger, to the control cell. battery or supplying current from the battery cell to a mobile phone, an mp3 player, etc. Preferably, the external input and output terminal is configured to have a plate structure in which a connector is mounted at one end of it.
A nickel plate can also be mounted on top of the cathode terminal, which is coupled to the connection part with the cathode terminal, by ultrasonic welding. Consequently, precarious welding is prevented between the cathodic terminal of the battery cell, which is generally made of aluminum, and the connection part with the cathodic terminal, which is nickel fair, due to different properties between them.
However, a label can be attached to the PCM, excluding the external input and output terminal, and to the external side of the battery cell, in order to cover the PCM and the battery cell. Specifically, the label can be configured to have a structure to cover the PCM, excluding the external input and output terminal, and the thermally welded external circumferences shown on the sides of the battery cell. Consequently, it is possible to steadily fix the external thermally welded circumferences to the main body of the battery cell, while generally maintaining an insulating state, thus ensuring a more stable electrical connection between the electrode terminals. of the battery cell and the PCB.
Preferably, the secondary battery pack according to the present invention is a built-in type secondary battery pack.
In accordance with another aspect of the present invention, a protective circuit module of specific structure is presented which is used to constitute the secondary battery pack with the aforementioned construction.
Specifically, a protection circuit module (PCM) is presented to be mounted on top of a plate-shaped battery cell that has electrode terminals, each of which is made of a plate-shaped conductive element, formed at the upper end of it, where the PCM includes a printed circuit board (PCB) that has a protection circuit formed on it, the PCB being provided, on one side of it, with a connection part with the cathodic terminal and a part of connection with the anodic terminal and, on the other side of it, a connection part with the input terminal and the external output terminal, an external input and output terminal electrically connected to the PCB protection circuit via the connection part with the external input and output terminal of the PCB, and an electrically insulating PCM box, in which the PCB is mounted in the manner of insertion in a state in which an anode terminal and a cathode terminal are electrically connected to the PCB .
In the general process of assembling a secondary battery pack of the built-in type, a connecting element and a PCM are coupled and an insulating tape is attached at each step, so that a set of PCM is mounted in a battery cell. That is, the PCM assembly is mounted on the battery cell using a large number of parts. Consequently, a large number of processes are required. In addition, the mechanical strength and structural stability of the battery pack is low.
On the other hand, the protection circuit module according to the present invention is configured to have a structure in which the PCB is mounted in the PCM box. Consequently, the structural stability of the battery pack is improved and the manufacturing process of the battery pack is considerably simplified.
In addition, the PCB is loaded onto the thermally welded surplus portion of the battery cell in the direction in which the PCN faces the upper end of the main body of the battery cell through the specific structure mentioned above and, therefore, it is possible to increase over maximum battery cell capacity compared to battery packs that have the same standard.
In a preferred example, the external input and output terminal can be connected to one side of the PCB, and the connection part to the anode terminal and the connection part to the cathode terminal can be formed on the other side of the PCB so that the connection part with the anode terminal and the connection part with the cathode terminal correspond to the anode terminal and the cathode terminal, respectively.
Preferably, the external input and output terminal is configured to have a plate structure in which a connector is mounted at one end of it.
Preferably, the PCM box is configured to have a hollow box structure, one end of which is opened in the form of a slot, through which the PCB is inserted.
In accordance with another aspect of the present invention, a method for making the secondary battery pack of the above construction is presented.
Specifically, the secondary battery pack according to the present invention can be manufactured using a method to manufacture a secondary battery pack that includes (a) connecting a nickel plate to the top of a cathode terminal on a battery cell by ultrasonic welding, (b) connect an anode terminal and the cathode terminal of the battery cell to a connection part with the anode terminal and a connection part with the cathode terminal, formed on the back of a PCB, by welding by points, (c) bend a PCM so that the connection part with the anode terminal and the connection part with the cathode terminal are arranged in parallel with respect to the battery cell, (d) insert the PCM in a box of PCM configured to have a hollow box structure formed so that an external input and output terminal extends outward, (e) bend the electrode terminals of the battery cell and mount the PCM in an excess part te thermally welded from the battery cell and (f) cover the PCM, excluding the external input and output terminal, and the external side of the battery cell with a label.
Compared to the method of making a secondary battery pack of the conventional built-in type, the method of making the secondary battery pack according to the present invention can reduce the number of manufacturing processes and obtain a secondary battery pack that presents stability structural improvement.
In addition, in the secondary battery pack manufacturing method, it is possible to obtain PCM protection and insulation using the PCM box without an additional element, such as a label or electrical tape, and the box is assembled after the PCB is electrically connected to the electrode terminals and the folding process is completed. Consequently, no exposure region is formed during the folding process and, therefore, no additional insulating material is required.
Depending on the circumstances, the method of making the secondary battery pack may also include attaching an insulating tape to the region of exposure to the electrode terminals of the thermally welded surplus before the folding step.
Advantageous effects As is evident from the description above, in the secondary battery pack according to the present invention, the protection circuit module (PCM), which includes the PCM box, is loaded over the thermally welded excess part of the battery cell . Consequently, it is possible to simplify the battery pack assembly process and improve the structural stability of the battery pack.
In addition, the secondary battery pack according to the present invention has a specific internal structure, thus obtaining the maximum capacity compared to battery packs that have the same pattern.
In addition, in the PCM according to the present invention, the PCM is protected from external impacts, the dimensional stability of the PCM is high and the PCM is arranged on the outside of the battery pack while having a clean, pleat-free appearance.
