由于在大型储能领域中,需要很多装有储能电池模块的电池插箱,并且为节省空间和操作方便,多个电池插箱通常会相邻布置。当多个电池插箱需要并联汇流时,技术人员一般会采用软导线将多个电池插箱的正输出端子接在一起,负输出端子接在一起,从而实现多个电池插箱的汇流。但是,如图1所示,采用软导线引接时,势必会造成导线间的相互交叠。该种汇流形式下,正输出端子与负输出端子之间的安全距离较小,当引出的软导线流过大电流时,随着使用时间的增加,软导线之间的绝缘性能降低,很容易发生正负极之间的短路故障。Because in the field of large-scale energy storage, many battery insertion boxes equipped with energy storage battery modules are required, and in order to save space and facilitate operation, multiple battery insertion boxes are usually arranged adjacent to each other.

实施例1Example 1
如图2所示,本发明实施例提供了一种储能电池模组,该储能电池模组包括:多个储能电池模块2、正极汇流排4和负极汇流排5。As shown in FIG. 2 , an embodiment of the present invention provides an energy storage battery module. The energy storage battery module includes: a plurality of energy storage battery modules 2 , a positive electrode bus bar 4 and a negative
储能电池模块2由若干储能电池单体1串并联构成,储能电池模块2上成型有正极输出端和负极输出端,并且正极输出端与负极输出端存在有一定的距离。所有储能电池模块2的正极输出端全部连接到正极汇流排4,所有储能电池模块2的负极输出端全部连接到负极汇流排5。由于正极输出端与负极输出端存在有一定的距离,使得正极汇流排4与负极汇流排5之间也存在有一定的距离。该距离本领域技术人员可根据实际情况进行确定。The energy storage battery module 2 is composed of a number of energy storage battery cells 1 in series and parallel. The energy storage battery module 2 is formed with a positive output terminal and a negative output terminal, and there is a certain distance between the positive output terminal and the negative output terminal. The positive output terminals of all the energy storage battery modules 2 are all connected to the positive bus bar 4 , and the negative output terminals of all the energy storage battery modules 2 are all connected to the
如此设置,通过将储能电池模块2的正极输出端与正极汇流排4连接,负极输出端与负极汇流排5连接,使得多个储能电池模块2之间无需通过软导线连接。在多个储能电池模块2均通过正极汇流排4和负极汇流排5连接后,由于正极汇流排4与负极汇流排5之间存在一定距离,所以不会发生短路情况,从而解决了储能电池模块2正负极之间的短路故障。In this way, by connecting the positive output end of the energy storage battery module 2 to the positive bus bar 4, and the negative output end to the
可选地,在本发明的一些实施例中,储能电池模块2的正极输出端与负极输出端相对设置于储能电池模块2的两侧。Optionally, in some embodiments of the present invention, the positive output terminal and the negative output terminal of the energy storage battery module 2 are disposed opposite to both sides of the energy storage battery module 2 .

In addition, since the energy storage battery module 2 of the present application is open-type compared to the battery insert box in the prior art, when a fault occurs inside the energy storage battery module 2, the faulty energy storage battery cell 1 can be processed. For replacement, there is no need to replace the entire energy storage battery module 2 .
而且,在储能电池单体1的电池容量衰减至额定容量的预设值以下时,直接将保护器3断开,可以直接对储能电池单体1进行更换,从而可以对被更换的储能电池单体1进行资源化处理,实现储能电池单体1的梯次利用。从而起到降低储能电池模块2故障率,提高储能电池模组的稳定性、组装灵活性的效果,最终能提升储能电池模组的安全性和整体发电效率。Moreover, when the battery capacity of the energy storage battery cell 1 decays below the preset value of the rated capacity, the protector 3 is directly disconnected, and the energy storage battery cell 1 can be directly replaced, so that the replaced storage battery can be replaced. The energy storage battery cells 1 are processed for resource utilization, so as to realize the cascade utilization of the energy storage battery cells 1 . Thereby, the failure rate of the energy storage battery module 2 is reduced, the stability and assembly flexibility of the energy storage battery module are improved, and the safety and overall power generation efficiency of the energy storage battery module can be finally improved.

顶板设置在电池架7的顶部,并适于将电池架7的顶部封闭。柜板设置在电池架7的一侧或者是多测,柜门通过转轴可旋转地设置在电池架7上。顶板、柜板以及柜门包围形成有内部空间。柜门适于将电池腔完全封闭。The top plate is arranged on the top of the
本发明通过设置顶板、柜板和柜门,可以保证储能电池模组在电池架7上正常工作时,不受周围环境中的灰尘以及杂质的影响,能够更好地保证储能电池模组的正常工作。同时,设置柜门还方便技术人员对电池架7上的储能电池单体1进行更换。By arranging the top plate, the cabinet plate and the cabinet door, the present invention can ensure that the energy storage battery module is not affected by dust and impurities in the surrounding environment when the energy storage battery module works normally on the
本发明还将顶板、柜板和柜门设置为透明材质,如此可以使技术人员能够实时地观察到电池架7上储能电池模块2的工作状态,从而提高了技术人员的工作效率。In the present invention, the top plate, the cabinet plate and the cabinet door are also made of transparent materials, so that the technician can observe the working state of the energy storage battery module 2 on the
作为一种可选的实施方式,本发明在柜板以及柜门设置有适于纯南瓜电池模组散热的散热区。如此,可以保证储能电池模块2工作时产生的热量能够及时地散发至外界,从而保证了储能电池模块2的正常工作。As an optional embodiment, in the present invention, the cabinet board and the cabinet door are provided with a heat dissipation area suitable for heat dissipation of the pure pumpkin battery module. In this way, it can be ensured that the heat generated by the energy storage battery module 2 can be dissipated to the outside in time, thereby ensuring the normal operation of the energy storage battery module 2 .
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方式的限定。对于所属领域的普通工人来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For ordinary workers in the field, changes or changes in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And the obvious changes or changes derived from this are still within the protection scope of the present invention.
