It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
实施例一 Embodiment 1
图1为本发明电池模组实施例的***图，图2为本发明电池模组实施例的整体结构示意图，如图1和图2所示，本实施例的电池模组，可以包括：底部绝缘壳11、若干电池12、顶部绝缘壳13、导电元件14、电池上盖15以及外接导柱16。1 is an exploded view of an embodiment of a battery module of the present invention, and FIG. 2 is a schematic view showing an overall structure of a battery module according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the battery module of the present embodiment may include: a bottom portion The insulating case 11, the plurality of batteries 12, the top insulating case 13, the conductive member 14, the battery upper cover 15, and the external guide post 16.
本实施例的电池模组可用于通讯基站以及光伏储能***等环境中，其中，电池12可以使用铅蓄电池、锂离子电池等电池，并且顶盖上还可以设置有配套的防爆阀，底部绝缘壳11包括底板和侧板，且底板和侧板形成底部固定槽111。如图1所示，底部绝缘壳11使用3个较短的侧板和2两个较长的侧板形成两个用于与电池12的底部相匹配的底部固定槽111，相邻两个底部固定槽111之间留有间隙，以利于电池12固定在底部固定槽111中，相邻的电池12之间留有空隙，有利于电池12进行散热，且还可以防止电池12之间相互 触碰而易发生短路的危险。电池12与底部绝缘壳11装配时，若干电池12以侧面相邻的形式排布构成一个供电单元，供电单元的底部嵌入底部固定槽111中。如图1所示，电池12共有6块，其中3块以侧面相邻的形式排布，放置在一个底部固定槽111中，另外3块以侧面相邻的形式排布，放置在另一个底部固定槽111中，通过将供电单元嵌入底部固定槽111的方式，实现了提高空间利用率的效果。The battery module of the embodiment can be used in a communication base station and a photovoltaic energy storage system, wherein the battery 12 can use a lead battery, a lithium ion battery, etc., and the top cover can also be provided with a matching explosion-proof valve, and the bottom insulation The case 11 includes a bottom plate and side plates, and the bottom plate and the side plates form a bottom fixing groove 111. As shown in FIG. 1, the bottom insulating case 11 uses three shorter side plates and two longer side plates to form two bottom fixing grooves 111 for matching the bottom of the battery 12, adjacent to the bottom two. A gap is left between the fixing grooves 111 to facilitate the fixing of the battery 12 in the bottom fixing groove 111, and a gap is left between the adjacent batteries 12 to facilitate heat dissipation of the battery 12, and also prevent the batteries 12 from mutually interacting with each other. The risk of short circuit is easy to touch. When the battery 12 is assembled with the bottom insulating case 11, a plurality of batteries 12 are arranged side by side to form a power supply unit, and the bottom of the power supply unit is embedded in the bottom fixing groove 111. As shown in Fig. 1, the battery 12 has a total of six pieces, three of which are arranged side by side, placed in one bottom fixing groove 111, and the other three are arranged side by side and placed at the other bottom. In the fixing groove 111, the effect of improving the space utilization rate is achieved by embedding the power supply unit in the bottom fixing groove 111.
为了将电池12的能量得到汇聚，可以使用一定的连接方式将各个电池12连接起来，由于连接过程中需要使用连接线或其他导电的部件来实现，容易发生短路的风险，因此需要在供电单元的顶部设置顶部绝缘壳13，顶部绝缘壳13放置在供电单元中的各个电池12上方，顶部绝缘壳13上设置有顶部固定槽(图中未示出)，电池12的极柱均从顶部固定槽伸出，在实现了将电池12与其他容易导电的部件隔离的同时，还方便了电池12之间连接的效果。In order to concentrate the energy of the battery 12, each battery 12 can be connected by using a certain connection method. Since the connection line or other conductive components are needed in the connection process, the risk of short circuit is easy to occur, so it is required in the power supply unit. The top is provided with a top insulating case 13 which is placed above each of the batteries 12 in the power supply unit. The top insulating case 13 is provided with a top fixing groove (not shown), and the poles of the battery 12 are fixed from the top. Extending, while the battery 12 is isolated from other easily conductive components, the effect of the connection between the batteries 12 is also facilitated.
在提高空间利用率的同时，还需要调整电池12的排布顺序，因此，可以采用将电池模组内的电池12采用串联的方式来实现，通过使用导电元件14将所有电池12以及外接导柱16依次串联形成第一电路结构，导电元件14设置在顶部绝缘壳13背离供电单元的一侧，外接导柱16可以为两个，其中一个为正极外接导柱，另一个为负极外接导柱，两个外接导柱16分别位于第一电路结构的首尾两端，使用串联的方式连接电池12，不会因为电池12排布顺序不同而受影响，实现了便于使用的效果。While improving the space utilization rate, it is also necessary to adjust the arrangement order of the batteries 12. Therefore, the battery 12 in the battery module can be implemented in a series manner, and all the batteries 12 and the external guide columns are used by using the conductive elements 14. 16 is sequentially connected in series to form a first circuit structure, the conductive element 14 is disposed on a side of the top insulating shell 13 facing away from the power supply unit, and the external guiding pillars 16 may be two, one of which is a positive external guiding pillar and the other is a negative external guiding pillar. The two external guide posts 16 are respectively located at the first and last ends of the first circuit structure, and the battery 12 is connected in series, which is not affected by the arrangement order of the batteries 12, and the effect of being convenient to use is achieved.
另外，两个外接导柱16作为整个第一结构的能量输出端，且还需要露出至电池上盖15的外面共其他连接部件连接使用，在电池上盖15套设在顶部绝缘壳13远离电池12的一侧时，使得两个外接导柱16均露出顶部绝缘壳13及电池上盖15。电池上盖15可以采用塑料制成，用于遮挡整个电池模组的上部的同时还具有绝缘的功能，实现了避免电池模组内部相互接触，或与外界的可以导电的元件接触而出现短路危险的效果。In addition, the two external guide posts 16 serve as energy output ends of the entire first structure, and also need to be exposed to the outside of the battery cover 15 for connection with other connecting components. The battery cover 15 is sleeved on the top insulating case 13 away from the battery. At one side of the 12, the two external guide posts 16 are exposed to the top insulating case 13 and the battery upper cover 15. The battery cover 15 can be made of plastic to shield the upper part of the battery module and also has an insulating function, so as to avoid the danger of short circuit when the battery modules are in contact with each other or contact with external conductive components. Effect.
此外，在对电池12进行连接时，还可以采用并联的方式，也可以采用串并联并存的方式，本实施例中的电池12的连接方式仅为示例性说明，并不是唯一的连接方式，具体的连接方式以实际应用中为准。In addition, when the battery 12 is connected, the parallel connection may be adopted, or the serial and parallel connection may be adopted. The connection manner of the battery 12 in this embodiment is only an exemplary description, and is not the only connection manner. The connection method is subject to the actual application.
其中，底部绝缘壳11和顶部绝缘壳13可以采用塑胶制成，在实现良好的绝缘效果的同时还能够减轻重量，且还可以降低成本。 Among them, the bottom insulating case 11 and the top insulating case 13 can be made of plastic, which can reduce the weight while achieving good insulation effect, and can also reduce the cost.
因为电池12的极柱的长度是固定的，因此为了使得焊接效果更加的良好，可以使用导电元件14来与电池12的极柱进行焊接，例如可以采用片状金属材料制成，为了方便于焊接，使用在顶部绝缘壳13设置的有用于电池12的极柱伸出的顶部固定槽以将各个极柱隔开，避免在安装过程中，各个电池12的极柱碰到一起而引起短路，实现了将顶部绝缘壳13安装在电池12上的时候，可以将极柱露出而利于进行焊接的效果。Since the length of the pole of the battery 12 is fixed, in order to make the welding effect more favorable, the conductive member 14 can be used for welding with the pole of the battery 12, for example, a sheet metal material can be used for the convenience of welding. The top fixing groove provided for the poles of the battery 12 is disposed at the top insulating shell 13 to separate the poles, so as to avoid short-circuiting caused by the poles of the respective batteries 12 during the installation process. When the top insulating case 13 is mounted on the battery 12, the poles can be exposed to facilitate the soldering effect.
其中，导电元件14包括输出电极元件141和转接元件142，图3为本发明电池模组实施例的局部结构示意图，如图3所示，使用转接元件142连接所有电池12，在实际应用的过程中，转接元件142可以使用具有良好导电性的铝巴，且在转接元件142上开设与极柱相匹配的方形孔，通过激光焊接的方式将铝巴与电池12的极柱焊接在一起。使用输出电极元件141分别连接外接导柱16以及电池12，在实际应用的过程中，输出电极元件141优选采用具有连接强度较好的铜巴，以避免因铝巴的连接强度不足容易导致阻抗过大的问题，通过超声波焊接的方式将铜巴与外接导柱16以及极柱焊接在一起。The conductive element 14 includes an output electrode element 141 and an adapter element 142. FIG. 3 is a partial schematic structural view of an embodiment of the battery module of the present invention. As shown in FIG. 3, all the batteries 12 are connected by using the switching element 142. During the process, the switching element 142 can use an aluminum bar with good conductivity, and a square hole matching the pole is formed on the switching element 142, and the aluminum bar is welded to the pole of the battery 12 by laser welding. Together. The output electrode element 141 is used to connect the external lead post 16 and the battery 12 respectively. In the actual application process, the output electrode element 141 preferably uses a copper bar with good connection strength to avoid the impedance caused by the insufficient connection strength of the aluminum bar. The big problem is that the copper bar is welded to the external guide post 16 and the pole by ultrasonic welding.
根据电池12的数量来匹配转接元件142的数量，输出电极元件141的数量与外接导柱16的数量相对应。The number of the switching elements 142 is matched according to the number of the batteries 12, and the number of the output electrode elements 141 corresponds to the number of the external guide posts 16.
为了将焊接好的导电元件14固定，可以在顶部绝缘壳13远离电池12的一侧表面上设置导电元件凹槽131，导电元件凹槽131的数量与导电元件14的数量一致，并将焊接好的导电元件14嵌入导电元件凹槽131中。实现了通过导电元件凹槽131将导电元件14固定，提高安全性以及可靠性的效果。In order to fix the soldered conductive member 14, a conductive member recess 131 may be disposed on a side surface of the top insulating shell 13 away from the battery 12. The number of conductive member recesses 131 is the same as the number of conductive members 14, and will be soldered. The conductive element 14 is embedded in the conductive element recess 131. The effect of fixing the conductive member 14 through the conductive member groove 131 is achieved, improving safety and reliability.
为了安装方便，还可以在顶部绝缘壳13靠近电池12的一侧表面上还设置导电元件凹槽131，并且顶部绝缘壳两侧的导电元件凹槽131对称设置，在靠近电池12的一侧表面上设置有导电元件凹槽131在方便安装的同时一定程度上还可以起到保护电池12的极柱的作用。For the convenience of installation, a conductive element groove 131 may also be disposed on a side surface of the top insulating case 13 adjacent to the battery 12, and conductive element grooves 131 on both sides of the top insulating case are symmetrically disposed on a side surface close to the battery 12. The conductive element groove 131 is provided on the side of the battery 12 to protect the pole of the battery 12 to a certain extent.
本实施例中的电池模组可以使用在通讯基站以及光伏储能***等环境中，通信基站或光伏储能***等大都处于室外的环境，因室外环境的温度会随着天气的变化而变化，无法保持一个适于电池模组发挥最佳效果的良好温度。因此，可以在电池模组中增加加热膜片17的部件，图4为本发明电池模组实施例的另一局部结构示意图，如图4所示，加热膜片17包括膜片本体171、膜片导线172及插头173。其中，膜片导线172的一端连接在膜片本体 171上，且膜片导线172的另一端连接插头173，插头173可用于连接电池模组内的电路板或电池模组外的的其他设备，如电源管理***等。为了使得加热膜片17可以对电池12良好的加热，需要与电池12紧密的接触，以利于热量的传递。因此，膜片本体171设置在底部固定槽111内，因底部绝缘壳11与电池12的尺寸相匹配，就需要将膜片导线伸出至底部绝缘壳11外部，所以底部绝缘壳11设置有导线出孔112，膜片导线172穿过导线出孔112。实现了通过加热膜片17对电池12进行加热的效果。The battery module in this embodiment can be used in an environment such as a communication base station and a photovoltaic energy storage system, and the communication base station or the photovoltaic energy storage system is mostly in an outdoor environment, because the temperature of the outdoor environment changes with the weather. It is not possible to maintain a good temperature suitable for the best performance of the battery module. Therefore, the components of the heating film 17 can be added to the battery module. FIG. 4 is another partial structural view of the battery module embodiment of the present invention. As shown in FIG. 4, the heating film 17 includes the diaphragm body 171 and the film. Sheet conductor 172 and plug 173. Wherein one end of the diaphragm wire 172 is connected to the diaphragm body 171, and the other end of the diaphragm wire 172 is connected to the plug 173, and the plug 173 can be used to connect a circuit board in the battery module or other equipment outside the battery module, such as a power management system. In order for the heating diaphragm 17 to heat the battery 12 well, close contact with the battery 12 is required to facilitate heat transfer. Therefore, the diaphragm body 171 is disposed in the bottom fixing groove 111. Since the bottom insulating case 11 is matched with the size of the battery 12, it is necessary to project the diaphragm wire to the outside of the bottom insulating case 11, so that the bottom insulating case 11 is provided with a wire. Outlet 112, diaphragm wire 172 passes through wire exit opening 112. The effect of heating the battery 12 by heating the diaphragm 17 is achieved.
另外，膜片本体171采用可变形的材料制成，使得安装过程中，膜片本体171可随着底部固定槽111的形状而弯折，实现了提高膜片本体171与电池12之间的贴合度的效果。In addition, the diaphragm body 171 is made of a deformable material, so that the diaphragm body 171 can be bent along the shape of the bottom fixing groove 111 during the mounting process, thereby improving the adhesion between the diaphragm body 171 and the battery 12. The effect of the degree of convergence.
加热膜片17的数量可以随着底部固定槽111的数量多少来进行设定，以利于根据需要对电池12进行加热。The number of heated diaphragms 17 can be set with the number of bottom fixing slots 111 to facilitate heating of the battery 12 as needed.
使用加热膜片17在对电池12进行加热的过程中，还需要对加热的时间及加热的效果等进行控制，因上述结构中，没有体现出可以知晓电池12温度的部件，因此在上述结构的基础上增加了采样端子18、第一线束19和第二线束20，采样端子18的数量在实际应用过程中，可以根据电池12的数量多少来进行确定。采样端子18用于电池12温度的采样，将每个采样端子18一端分别与导电元件14采用超声波焊接方式连接，每个采样端子18的另一端连接第一线束19，第一线束19可以根据需要连接电路板或外部的温度控制***等用于控制加热的装置，使用采样端子18连接导电元件14后，就可以通过采样端子18采集电池12的温度，并通过第一线束19将温度信息传递至电路板或其他温度控制***等装置，实现了可以根据采样端子18采集的温度信息来控制加热膜片17在电池12需要加热的时候进行加热，在电池12温度达到标准后停止加热，有利于使得电池12的温度达到理想工作状态时的所需温度的效果。In the process of heating the battery 12 by using the heating film 17, it is necessary to control the heating time, the heating effect, and the like. Since the above structure does not exhibit a member that can know the temperature of the battery 12, the above structure is The sampling terminal 18, the first wire harness 19 and the second wire harness 20 are added on the basis, and the number of the sampling terminals 18 can be determined according to the number of the batteries 12 in actual application. The sampling terminal 18 is used for sampling the temperature of the battery 12, and one end of each sampling terminal 18 is respectively connected to the conductive element 14 by ultrasonic welding, and the other end of each sampling terminal 18 is connected to the first wire harness 19, and the first wire harness 19 can be as needed. A device for controlling heating, such as a circuit board or an external temperature control system, is used. After the conductive member 14 is connected using the sampling terminal 18, the temperature of the battery 12 can be collected through the sampling terminal 18, and the temperature information is transmitted to the first wire harness 19 to The circuit board or other temperature control system and the like realize that the heating film 17 can be controlled according to the temperature information collected by the sampling terminal 18 to heat when the battery 12 needs to be heated, and the heating is stopped after the temperature of the battery 12 reaches the standard, which is advantageous for making The effect of the temperature of the battery 12 to the desired temperature at the desired operating state.
为了判断电池模组在使用过程中的是否正常，还需要知道电池模组的电压数值，通过使用第二线束20分别连接导电元件14，以通过第二线束20来获取供电单元中的每个电池12的电压，以及整体的输出电压等数据，实现了有利于使用者根据电压数值来判断电池模组的工作状态是否正常。In order to judge whether the battery module is normal during use, it is also necessary to know the voltage value of the battery module, and connect the conductive elements 14 respectively by using the second wire harness 20 to obtain each battery in the power supply unit through the second wire harness 20. The voltage of 12 and the overall output voltage and other data enable the user to judge whether the working state of the battery module is normal according to the voltage value.
本实施例中的电池模组在实际应用过程中，采样端子18可以与铝巴以及 铜巴之间采用超声波焊接在一起，并且可以在铝巴上开圆孔并将第二线束20穿过圆孔与铝巴进行焊接，以避免因为外接的振动时产生较大的拉拔力使得第二线束20与铝巴脱落。还可以在铜巴和铝巴上开设方形孔，使得电池12的极柱可以从铜巴和铝巴上开设的方形孔穿过，便于极柱与铝巴和铜巴进行激光焊接。第一线束19和第二线束20可以捋顺在同一方向上，防止相互之间发生缠绕。In the actual application process of the battery module in this embodiment, the sampling terminal 18 can be combined with the aluminum bar and The copper bars are ultrasonically welded together, and a circular hole can be opened in the aluminum bar and the second wire harness 20 can be welded to the aluminum bar through the round hole to avoid a large pulling force due to the external vibration. The second wire harness 20 and the aluminum bar are detached. It is also possible to form a square hole in the copper bar and the aluminum bar so that the pole of the battery 12 can pass through the square hole opened in the copper bar and the aluminum bar, so that the pole column can be laser welded with the aluminum bar and the copper bar. The first wire harness 19 and the second wire harness 20 can be twisted in the same direction to prevent entanglement with each other.
为了保护电池模组内的导电元件14以及第一线束19、第二线束20，本实施例的电池模组还设置有螺钉21，在顶部绝缘壳13上设置有螺纹孔132，在电池上盖15设置有螺钉孔151，将螺钉21从螺钉孔151穿过后与螺纹孔132螺纹连接。其中，在实际生产顶部绝缘壳13的时候，螺纹孔132可以依靠注塑成型的内嵌螺母的形式实现。将电池上盖15与顶部绝缘壳13锁紧以后，就可以实现具有导电功能的部件与外界的导电部件隔离，提高了电池模组的安全性与可靠性的效果。In order to protect the conductive element 14 and the first wire harness 19 and the second wire harness 20 in the battery module, the battery module of the embodiment is further provided with a screw 21, and the top insulating shell 13 is provided with a threaded hole 132 for covering the battery 15 is provided with a screw hole 151, and the screw 21 is threadedly connected to the threaded hole 132 after passing through the screw hole 151. Wherein, when the top insulating case 13 is actually produced, the threaded hole 132 can be realized in the form of an injection molded in-line nut. After the battery upper cover 15 and the top insulating case 13 are locked, the conductive member can be isolated from the external conductive member, thereby improving the safety and reliability of the battery module.
使用螺钉21锁紧电池上盖15与顶部绝缘壳13的时候，如果用力过大，可能会使得顶部绝缘壳13发生变形或损坏，因此可以在顶部绝缘壳13远离电池12的一侧表面上设置有加强筋，用于加固顶部绝缘壳13，例如，可以设置在导电元件凹槽131附近，还可以设置在顶部绝缘壳13的四个角，又可以设置在螺钉孔151的附近等需要加固的地方。When the battery upper cover 15 and the top insulating case 13 are locked by the screw 21, if the force is excessively large, the top insulating case 13 may be deformed or damaged, and thus may be disposed on the side surface of the top insulating case 13 away from the battery 12. There is a reinforcing rib for reinforcing the top insulating shell 13, for example, it may be disposed near the conductive member groove 131, or at the four corners of the top insulating shell 13, or may be disposed near the screw hole 151 and the like. local.
由于不同的使用环境所需要的电池模组也会不同，因此电池12的数量也是不固定的，电池12数量越多，使用的线束19就会越多，线束19过多会呈现相互缠绕比较杂乱的现象，因此，可以在顶部绝缘壳13设置有用于捆绑线束的扎带孔133，还可以在顶部绝缘壳13上设置多个走线槽，用于线束19走线并方便固定。将线束按照一定的顺便排布在走线槽中以后，使用扎带穿过扎带孔133，将线束19固定。实现了电池模组内部线束19排列整齐，且避免了因为振动而容易导致线束19间相互摩擦而导致短路事故发生的效果。Since the battery modules required for different environments are different, the number of batteries 12 is also not fixed. The more the number of batteries 12, the more harness 19 is used, and the harness 19 is too entangled. Therefore, the top insulating case 13 may be provided with a strap hole 133 for binding the wire harness, and a plurality of wire grooves may be provided on the top insulating case 13 for the wire harness 19 to be routed and conveniently fixed. After the wire harness is arranged in the wire trough according to a certain convenience, the wire harness 19 is fixed by passing the cable tie through the cable tie hole 133. The inner wiring harness 19 of the battery module is arranged neatly, and the effect that the short-circuit accident occurs due to friction between the wire harnesses 19 easily due to vibration is avoided.
