Title: Expansion member for probe for charging and discharging battery and probe including the same

Description:
TECHNICAL FIELD 
     The present disclosure relates to an expansion member for a probe for battery charging and discharging and a probe including the same, and more particularly, to an expansion member for a probe of a charger and discharger, which can come into contact with posts provided on both sides of a prismatic battery, and a probe including the same. 
     BACKGROUND ART 
     In general, a rechargeable battery is a power source for a portable electronic device for information communication, such as a mobile phone, a tablet PC or a notebook computer, an electric bicycle, an electric vehicle, etc., and a demand for the rechargeable battery suddenly increases. 
     A process of manufacturing the rechargeable battery may be basically divided into an electrode process, a stacking process, an activation process, a test process, etc. The activation process means a process of activating a stacked battery (or a battery cell) so that the stacked battery can be used. Specifically, during the activation process, the battery is charged and discharged by supplying a voltage and a current to the battery. 
     For the charging and discharging of the battery, after a probe including an electrode is brought into contact with the battery, a current or a voltage is supplied to the electrode included in the battery through the probe. Accordingly, the probe is commonly disposed at a position corresponding to the electrode of the battery. 
     The battery is divided into a prismatic type, a pouch type and a cylindrical type. Among them, an electrode of the prismatic battery is commonly provided on the top of the battery. In this case, a probe for the charging and discharging of the battery is also disposed on the top of the battery. If the electrode of the prismatic battery is provided on the side of the battery, the probe also needs to be disposed on the side of the battery. However, if the probe is disposed on the side of the battery, it is necessary to efficiently dispose the probe on the side of the battery because there is a good possibility that the probe may interfere with the battery in an arrangement aspect. In particular, if additional pressurization means for bringing the probe into contact with the battery is present, there is a problem in that a space occupied by the probe is increased. 
     Contents described in “Background Art” help understanding of the background of the present disclosure, and may include contents that are not disclosed conventional technologies.

     DISCLOSURE 
     Technical Problem 
     The present disclosure is intended to provide an expansion member included in a probe for battery charging and discharging, which enables a contact with an electrode of the battery without a separate pressurization apparatus. 
     Furthermore, the present disclosure is intended to provide a probe which enables battery charging and discharging although an electrode of a prismatic battery is disposed on both sides of the prismatic battery which face each other. 
     Objects to be solved by the present disclosure are not limited to the aforementioned objects, and the other objects not described above may be evidently understood from the following description by those skilled in the art. 
     Technical Solution 
     An expansion member for a probe for battery charging and discharging according to an embodiment of the present disclosure includes a first fluid accommodation part configured to form a space in which a fluid is introduced and stored and a fluid supply pipe equipped with a path along which the fluid is introduced and discharged and connected to the first fluid accommodation part. The first fluid accommodation part may include a first cover and a second cover. The first cover and the second cover may be bonded together to form a first fluid accommodation space in which the fluid is accommodated. The first fluid accommodation space may be surrounded by a first junction region in which the first cover and the second cover are bonded together. A penetration hole may be formed on the top of the first junction region. 
     A probe for the charging and discharging of a prismatic battery according to an embodiment of the present disclosure is a probe for charging and discharging of a prismatic battery, including a contact point unit disposed on one side of the probe and equipped, on one surface thereof, with an electrode part for providing a current to the prismatic battery, an expansion member disposed on another surface of the contact point unit and configured to expand when a fluid is introduced therein so that an electrode part comes into contact with an electrode of the prismatic battery, a support unit disposed on another side of the probe and configured to support the expansion member, and a connection unit coupled with the support unit configured to limit a moving direction of the expansion member. 
     Advantageous Effects 
     According to the present disclosure, the following effects may be obtained. 
     First, if an electrode of a battery is disposed on both sides of the battery which face each other, the battery can be charged and discharged in accordance with a location of the electrode. 
     Furthermore, since the expansion member is provided, an electrode of a battery can be charged and discharged without a separate pressurization apparatus for a contact with the electrode, such as a motor. Accordingly, space utilization can be improved because a space occupied by the motor for pressurization is obviated. 
     Furthermore, if a fluid is introduced into the expansion member, as the expansion member expands, the contact point unit comes into contact with an electrode of a battery. Accordingly, a pressure value of the contact point unit coming into contact with the electrode can be adjusted by adjusting the amount of the introduced fluid without replacing a separate part. 
     Furthermore, if a plurality of probes is fixed, more battery cells can be simultaneously charged and discharged because an interval between the probes can be more narrowed. 
     Effects of the present disclosure are not limited to the aforementioned effects, and effects not described above may be evidently understood from the following description by those skilled in the art.

       FIG.  1    is a diagram illustrating a structure in which a probe for the charging and discharging of a prismatic battery according to the present disclosure is provided in plural and coupled with a plurality of batteries  1 . 
     Referring to  FIG.  1   , the structure in which the probe for the charging and discharging of a prismatic battery according to an embodiment of the present disclosure is coupled with the plurality of batteries includes the battery  1 , a probe  10 , and a battery accommodation unit  20 . 
     An electrode of a conventional battery is disposed on the top of the battery, but an electrode of the battery  1  with which the probe  10  according to embodiments of the present disclosure comes into contact is disposed on both sides of the battery which face each other. 
     The battery accommodation unit  20  forms a space in which one or more batteries  1  can be accommodated, and further includes fitting units protruded toward the inside thereof on both sides of the battery which face each other. The probe  10  may be fitted and coupled to the fitting units. 
       FIG.  2   a    is a perspective view of the probe  10  for the charging and discharging of a prismatic battery according to the present disclosure.  FIG.  2   b    is an exploded perspective view of  FIG.  2   a   .  FIG.  3   a    is a cross-sectional view of  FIG.  2   a   .  FIG.  3   b    is a diagram illustrating the state in which a fluid has been introduced into an expansion member  200  in  FIG.  3     a.    
     Referring to  FIGS.  2   a ,  2   b ,  3   a  and  3   b   , the probe  10  includes a contact point unit  100 , the expansion member  200 , a support unit  300  and a connection unit  400 . 
     The contact point unit  100  is disposed on one side of the probe  10 . A current may be applied to the contact point unit  100  by a shunt  430 . In this case, the one side means a position neighboring an electrode of the battery  1 . 
     The contact point unit  100  comes into contact with the electrode of the battery  1  and supplies a current to the battery  1 . The contact point unit  100  according to embodiments of the present disclosure selectively comes into contact with the electrode of the battery  1  depending on whether a fluid is introduced into the probe  10 . The fluid may mean a gas or a liquid. For example, the fluid may be air. 
     The contact point unit  100  further includes an electrode part  110  and a guide hole  120 . 
     The electrode part  110  is disposed on one surface of the contact point unit  100 , and includes a pin insertion hole  111  and a voltage sensing pin  112 . The electrode part  110  is connected to the shunt  430  in a way to electrically communicate with the shunt. 
     According to embodiments, the electrode part  110  may be formed by performing surface processing on one surface of the contact point unit  100 . For example, the electrode part  110  may include a plurality of prominences and depressions formed on the contact point unit  100 . 
     In order to prevent a short circuit in the electrode part  110 , an insulation unit  130  is disposed between the contact point unit  100  and the expansion member  200 . 
     One or more pin insertion holes  111  may be provided. 
     The voltage sensing pin  112  is configured to detect a voltage of the battery  1  and disposed within the pin insertion hole  111 . 
     According to an illustrated embodiment, the voltage sensing pin  112  may be insulated from the electrode part  110 . For example, the voltage sensing pin  112  is isolated from the pin insertion hole  111  and disposed within the pin insertion hole  111 . An electric wire connected to the voltage sensing pin  112  is disposed within the insulation unit  130 , so that the voltage sensing pin  112  can be insulated from the electrode part  110 . 
     When the voltage sensing pin  112  detects a voltage of the battery  1 , a controller  700  to be described later controls a power unit  500  to apply a current to the electrode part  110 , and a detailed description thereof will be given later. 
     The guide hole  120  is provided to be coupled with one end of a guide part  410 . One or more guide holes  120  may be formed, and are formed in accordance with the number and positions of the guide part  410 . 
     A coupling member  411  of the guide part  410  may be protruded to the outside through one end of the guide part and fastened to the guide hole  120 . 
     The guide hole  120  is formed in an area of the contact point unit  100  other than the electrode part  110 . If the guide hole  120  is formed in the electrode part  110 , charging and discharging efficiency of the battery  1  may be reduced because a contact area between the electrode of the battery  1  and the electrode part  110  is reduced. 
     Furthermore, in the illustrated embodiment, it is preferred that the guide hole  120  has an internal diameter reduced from the battery  1  to the expansion member  200 . An external diameter of the coupling member  411  is formed in accordance with the internal diameter of the guide hole  120 . 
     It is preferred that an external diameter of one end of the coupling member  411  is greater than an internal diameter of a portion close to the electrode of the battery  1  of the guide hole  120 . In such a case, if a fluid leaks from the expansion member  200 , the coupling member  411  may attract the contact point unit  100  so that the contact point unit  100  returns to a position before the fluid is introduced into the expansion member  200  because a restoring force of an elastic member (not illustrated) is directed toward a direction that becomes distant from the contact point unit  100 . 
     The expansion member  200  is a structure for enabling the contact point unit  100  to expand and come into contact with the electrode of the battery  1  when a fluid is introduced therein, and is disposed on a surface opposite to a surface with which the electrode of the battery  1  of the contact point unit  100  comes into contact. 
     The support unit  300  is an element for supporting the expansion member  200 , and is disposed on the other side of the probe  10 . In this case, the other side means a position corresponding to the one side described in order to describe the position of the contact point unit  100 . 
     The support unit  300  is configured to fix a part of the probe  10  coupled with the fitting unit  21  of the battery accommodation unit  20  to be described later. 
     The support unit  300  may include a given element for being coupled and fixed to the fitting unit  21  of the battery accommodation unit  20 . For example, a screw or a bolt may correspond to the given element. 
     The connection unit  400  is an element coupled with the support unit  300  configured to limit a moving direction of the expansion member  200 , and a detailed description thereof is given later. 
       FIG.  4    is a perspective view illustrating that only the expansion member  200  in  FIG.  2   a    is separated and enlarged. 
     Referring to  FIG.  4   , the expansion member  200  further includes a fluid accommodation unit  210  and a fluid supply pipe  220 . 
     The fluid accommodation unit  210  includes a space in which a fluid introduced into the expansion member  200  is stored, and may be made of an elastic material. 
     The fluid accommodation unit  210  further includes a first fluid accommodation part  211  and a second fluid accommodation part  212 . 
     The first fluid accommodation part  211  is connected to the fluid supply pipe  220  to be described later and is configured to enable the inflow and outflow of a fluid through the fluid supply pipe  220 . 
     The second fluid accommodation part  212  is disposed by being overlapped with the first fluid accommodation part  211 . 
     The size of a cross-sectional area of the second fluid accommodation part  212  may be smaller than the size of a cross-sectional area of the first fluid accommodation part  211 . Specifically, it is preferred that the size of the second fluid accommodation part  212  corresponds to the size of the electrode part  110  so that the electrode of the battery  1  and the electrode part  110  are closely brought into contact with each other. 
     Furthermore, a penetration hole  214  through which the coupling member  411  of the guide part  410  can pass is provided in the fluid accommodation unit  210 . 
     The number of penetration holes  214  and a position where the penetration hole  214  is formed may be determined in accordance with the number and position of the guide part  410 , and a detailed description thereof is given later. 
     The fluid supply pipe  220  is connected to the fluid accommodation unit  210  and configured to enable the inflow and outflow of a fluid in and from the fluid accommodation unit  210 . Specifically, the fluid supply pipe  220  is connected to the first fluid accommodation part  211 , so that a fluid flows in and out of the first fluid accommodation part  211 . 
     The fluid supply pipe  220  is isolated from the penetration area of the penetration hole  214 . 
     A fluid that flows in and out through the fluid supply pipe  220  may be air, for example, a non-conductive gas. 
       FIG.  5    is a cross-sectional view of a cutting part taken along line A-A in  FIG.  4   .  FIG.  6    is a side cross-sectional view of the expansion member  200  in  FIG.  4   . 
     Referring to  FIGS.  5  and  6   , the first fluid accommodation part  211  forms a space in which a fluid may be introduced and stored, and further includes a first cover  2111  and a second cover  2112 . 
     The first cover  2111  and the second cover  2112  are bonded together in a way to form a first fluid accommodation space  2113  in which a fluid may be accommodated. 
     The first fluid accommodation space  2113  is surrounded by a first junction region  2114  in which the first cover  2111  and the second cover  2112  are bonded together. 
     The second fluid accommodation part  212  communicates with the first fluid accommodation part  211 , and is disposed to overlap the first fluid accommodation part  211 . The second fluid accommodation part  212  further includes a third cover  2121  and a fourth cover  2122 . 
     The third cover  2121  and the fourth cover  2122  are bonded together in a way to form a second fluid accommodation space  2123  in which a fluid may be accommodated. 
     The second fluid accommodation space  2123  is surrounded by a second junction region  2124  in which the third cover  2121  and the fourth cover  2122  are bonded together. 
     The penetration hole  214  is formed in the first junction region  2114  in which the first cover  2111  and the second cover  2112  are bonded together. 
     The penetration hole  214  may be formed in pair. It is preferred that a pair of penetration holes  214  is disposed to face each other with the first fluid accommodated space  2113  interposed therebetween. 
     Referring to  FIGS.  4  and  5    together, the fluid supply pipe  220  may be buried in and fixed to the first junction region  2114 . 
     If the fluid supply pipe  220  is fixed to the first junction region  2114 , although a fluid is introduced into the fluid supply pipe  220 , the fluid supply pipe  220  cannot be moved. Accordingly, the speed at which the fluid accommodation unit  210  is expanded can be predicted because the amount of a fluid introduced into the fluid accommodation unit  210  is constantly maintained. 
     If the fluid supply pipe  220  is not fixed to a specific location, when a fluid is introduced into the fluid supply pipe  220 , the fluid supply pipe  220  may be moved. In this case, the amount of the fluid introduced into the fluid accommodation unit  210  may not be constant. Furthermore, if the fluid supply pipe  220  collides against another element while moving, an unexpected problem in that charging and discharging efficiency of the electrode of the battery  1  is reduced due to the expansion of the expansion member  200  to be described later may occur. 
       FIG.  7    is a cross-sectional view of a cutting part taken along line B-B in  FIG.  4   . 
     Referring to  FIG.  7   , the second fluid accommodation part  212  is coupled with the first fluid accommodation part  211  so that a fluid communicates with the second fluid accommodation part  212  and the first fluid accommodation part  211  through a fluid hole  213 . Accordingly, when a fluid is introduced into the first fluid accommodation part  211 , the fluid may be introduced into the second fluid accommodation part  212  through the fluid hole  213 . 
     The fluid hole  213  has been described as being illustrated in a cross section corresponding to line B-B in  FIG.  4   , but embodiments of the present disclosure are not limited thereto. The fluid hole  213  may be formed in a given area between the first fluid accommodation part  211  and the second fluid accommodation part  212 . 
     In the illustrated embodiment, the fluid supply pipe  220  is connected to the upper part of the first fluid accommodation part  211  and isolated from the penetration hole  214 , but a position thereof is not essentially limited to the illustrated position. 
       FIG.  8    is a cross-sectional view of  FIG.  1   .  FIG.  9    is a diagram illustrating the state in which a fluid has been introduced into the expansion member  200  in  FIG.  8   . 
     Referring to  FIGS.  8  and  9   , when air is introduced into the expansion member  200 , one side of the expansion member  200  is expanded in a direction that becomes distant from the other side of the expansion member  200  in the state in which the other side of the expansion member  200  has been fixed by the support unit  300 . 
     As one side of the expansion member  200  is expanded, the contact point unit  100  coming into contact with the expansion member  200  becomes distant from the expansion member  200 . Accordingly, if a fluid is introduced into the expansion member  200  to the maximum, the electrode part  110  of the contact point unit  100  and the electrode of the battery  1  come into contact with each other. Accordingly, when a current flows into the electrode part  110  of the contact point unit  100 , the battery  1  may be charged and discharged. 
     A pressure value of the contact point unit coming into contact with the electrode may be adjusted without replacing a separate part by adjusting the amount of a fluid introduced into the fluid accommodation unit  210  of the expansion member  200 . 
     According to an embodiment of the present disclosure, the second fluid accommodation parts  212  may be disposed in parallel and connected to the first fluid accommodation part  211 . A connection between the first fluid accommodation part  211  and the second fluid accommodation part  212  is performed by the fluid hole  213 , and a description thereof has been given above and thus omitted. If the plurality of fluid accommodation units  210  is connected in parallel, pressure of the electrode part  110  of the contact point unit  100  which may be applied to the electrode of the battery  1  may be increased because the amount of a fluid accommodated in the fluid accommodation unit  210  is increased. Accordingly, there is an effect in that precise charging and discharging can be performed because the electrode of the battery  1  and one surface of the contact point unit  100  can be closely brought into contact with each other by strong pressure. 
     Furthermore, for a close contact, if a fluid is introduced into the expansion member  200  as described above and the contact point unit  100  becomes close to the electrode of the battery  1 , it is preferred that a cross section of one surface of the contact point unit  100  is moved and maintained to be perpendicular to a moving direction of the contact point unit  100 . To this end, the illustrated embodiments include the guide part  410 , a guide support part  420 , etc. The guide part  410 , the guide support part  420 , etc. are described in detail later. 
     Although the fluid accommodation unit  210  of the expansion member  200  includes only the first fluid accommodation part  211 , as the first fluid accommodation part  2110  is expanded, the electrode part  110  of the contact point unit  100  and the electrode of the battery  1  may come into contact with each other. 
     The connection unit  400  is an element coupled with the support unit  300  and configured to limit a moving direction of the expansion member  200 , and further includes the guide part  410 , the guide support part  420  and the shunt  430 . 
     The guide part  410  has one end coupled with the contact point unit  100  and the other end coupled with the support unit  300 . One or more guide parts  410  may be provided. 
     The guide part  410  further includes the coupling member  411 , a shaft  412  and an elastic member  413  therein. 
     The shaft  412  is provided within the guide part  410  and forms a center axis of the guide part  410  in the length direction thereof. The elastic member  413  is provided within the guide part  410  and provided in a form to surround the shaft  412 . The coupling member  411  is coupled with one end of the shaft  412  and protruded to the outside of the guide part  410 . A detailed description of an effect attributable to the coupling of the elastic member  413  and the coupling member  411  is given later. 
     The guide support part  420  includes a through hole  421  so that the guide part  410  can slide through the through hole  421  such that the moving direction of the guide part  410  is limited. 
     In the illustrated embodiment, when air is introduced into the expansion member  200  and the expansion member  200  is expanded toward the electrode of the battery  1 , the contact point unit  100  also moves toward the electrode of the battery  1 , and the guide part  410  connected to the contact point unit  100  also moves. At this time, the guide part  410  slides and moves along the through hole  421 . 
     In contrast, when a fluid is discharged from the expansion member  200 , the contact point unit  100  no longer moves toward the electrode of the battery  1 . Since the guide part  410  returns to its original position by a restoring force of the elastic member  413  included in the guide part  410 , the contact point unit  100  coupled with the guide part  410  is also detached from the electrode of the battery  1  and thus may return to its original position along the guide part  410 . 
     The shunt  430  is formed in a curved form in which one side thereof is brought into contact and connected with the contact point unit  100  and the other side thereof is coupled with the support unit  300 . The shunt  430  is flexibly configured. Accordingly, if the expansion member  200  is expanded due to the introduction of a fluid and the contact point unit  100  simultaneously moves toward the electrode of the battery  1 , a shape of the shunt  430  may be deformed accordingly. 
       FIG.  10    is a block diagram of a system including the probe for the charging and discharging of a prismatic battery according to the present disclosure. 
     Referring to  FIG.  10   , the system including the probe for the charging and discharging of a prismatic battery includes the probe  10 , the power unit  500 , a fluid supply unit  600  and the controller  700 . 
     The probe  10  is provided on both sides of each of one or more batteries  1  as described above, and may charge and discharge the batteries  1 . The probe  10  further includes the contact point unit  100 , the expansion member  200 , the support unit  300  and the connection unit  400 . 
     The probe  10  and the elements constituting the probe are the same as those described above, and a description thereof is omitted. 
     The power unit  500  may supply power to the probe  10 . The power unit  500  may include a given element for power supply. The power supply is a well-known technology, and a detailed description thereof is omitted. 
     The fluid supply unit  600  may supply a fluid to the probe  10 . The fluid supply unit  600  may include a given element for supplying a fluid. 
     The controller  700  may control the power supply of the power unit  500 , and further includes a sensor unit  710 . The controller  700  is connected to the sensor unit  710  in a way to electrically communicate therewith. 
     The sensor unit  710  is configured to detect voltage information of the battery  1  through the voltage sensing pin  112  provided in the electrode part  110 , and is connected to the controller  700  in a way to electrically communicate therewith. A method of detecting a voltage is a well-known technology, and a detailed description thereof is omitted. 
     In this case, when the sensor unit  710  detects the voltage information, the controller  700  receives the voltage information and generates control information based on the received voltage information so that the power unit  500  supplies a current to the electrode part  110 . 
       FIG.  11    is a perspective view of a fixture including the probe for the charging and discharging of a prismatic battery according to the present disclosure. 
     Referring to  FIG.  11   , the fixture including the probe for the charging and discharging of a prismatic battery includes the probe  10 , a power cable  800  and a fluid manifold  900 . 
     In the illustrated embodiment, the probe  10  is disposed in plural at given intervals. In this case, the support unit  300  and shunt  430  of the probe  10  are coupled and fixed to a frame  30 . The probe  10  and the elements constituting the probe are the same as those described above, and a description thereof is omitted. 
     The frame  30  further includes a first frame  31  and a second frame  32 , and a detailed description of the first frame  31  and the second frame  32  is given later. 
     The power cable  800  is an element for supplying a current to the probe  10 . To this end, the power cable  800  is connected to the shunt  430  in a way to electrically communicate therewith. 
     The fluid manifold  900  is configured to supply a fluid to the probe  10 , and is disposed in plural at given intervals. The fluid manifolds  900  are coupled and fixed to the frames  30 . 
       FIG.  12    is a cross-sectional view of  FIG.  11   . 
     Referring to  FIG.  12   , the shunt  430  is coupled with the first frame  31 . The support unit  300  is coupled with the second frame  32 . The fluid manifold  900  to be described later is disposed on the top of the second frame  32 . 
       FIG.  13    is an enlarged perspective view of  FIG.  11   . 
     Referring to  FIG.  13   , the probe  10  is disposed in plural at given intervals. A plurality of the shunts  430  is also coupled with the first frames  31 , respectively, at given intervals. 
     Each of the shunts  430  may be coupled with the same surface of the first frame  31 . 
     In this case, it is most preferred that a plurality of the shunts  430  is alternately coupled with surfaces of the first frames  31  which face each other. The power cable  800  is connected to the shunt  430  in a way to electrically communicate therewith as described above. In this case, the power cable  800  is thick so that a high voltage current can flow into the power cable  800 . Accordingly, if the shunts  430  are coupled with only the same surfaces of the first frames  31 , an installation interval between the probes  10  needs to be wide. 
       FIG.  14    is an enlarged perspective view of  FIG.  11   , which is viewed at another angle. 
     Referring to  FIG.  14   , the fluid manifold  900  is configured to supply a fluid to the probe  10 . To this end, one end of a fluid cable (not illustrated) and the fluid manifold  900  are coupled together. Specifically, the fluid manifold  900  is configured to store a fluid introduced therein through the fluid cable (not illustrated) and to supply the stored fluid to each of the fluid supply pipes  220  of the plurality of probes  10 . Accordingly, the expansion member  200  of the probe  10  may be expanded. 
     The fluid manifold  900  may be disposed in the second frame  32  at given intervals. In this case, surfaces of the fluid manifold  900  and another adjacent fluid manifold  900 , which face each other, may be connected by a connection pipe  910 . When a fluid is introduced into the fluid manifold  900  with which the fluid cable (not illustrated) is coupled, the fluid communicates with an adjacent fluid manifold  900  through the connection pipe  910 .
