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. When multiple battery sockets need to be combined in parallel, technicians generally use flexible wires to connect the positive output terminals and negative output terminals of the multiple battery sockets together, so as to realize the convergence of multiple battery sockets. However, as shown in Figure 1, when a flexible wire is used for guiding, it will inevitably cause the wires to overlap each other. In this type of confluence mode, the safety distance between the positive output terminal and the negative output terminal is small. When a large current flows through the lead flexible wire, the insulation performance between the flexible wires decreases with the increase of use time, and it is easy to A short-circuit fault between the positive and negative poles has occurred.

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 electrode bus bar 5 .

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 negative bus bar 5 . Since there is a certain distance between the positive output end and the negative output end, there is also a certain distance between the positive bus bar 4 and the negative bus bar 5 . The distance can be determined by those skilled in the art according to the actual situation.

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 negative bus bar 5, the plurality of energy storage battery modules 2 do not need to be connected by flexible wires. After the plurality of energy storage battery modules 2 are connected through the positive bus bar 4 and the negative electrode bus bar 5, since there is a certain distance between the positive electrode bus bar 4 and the negative electrode bus bar 5, a short circuit will not occur, thus solving the problem of energy storage.

该种汇流方法使得储能电池模块2正负极之间的距离被扩宽,进而使得引出的汇流排之间的距离也相应扩宽,汇流排的安全距离和强度提升,规避了载体间相互搭接的情况,降低了短路风险。This confluence method widens the distance between the positive and negative poles of the energy storage battery module 2, and further widens the distance between the drawn out bus bars. The safety distance and strength of the bus bars are improved, and the mutual support between the carriers is avoided. The overlapped condition reduces the risk of short circuits.

本发明通过将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,可以在最大程度上增加正极汇流排4与负极汇流排5之间的距离,从而保证储能电池模块2正负极之间不会发生短路故障。By arranging the positive output terminal and the negative output terminal on both sides of the energy storage battery module 2 opposite to each other, the present invention can increase the distance between the positive electrode bus bar 4 and the negative electrode bus bar 5 to the greatest extent, thereby ensuring the energy storage battery module 2 There will be no short circuit fault between positive and negative poles.

当然,保护器3还可以仅设置在正极输出端与正极汇流排4之间或者是负极输出端与负极汇流排5之间。本实施例仅仅是举例说明,并不对保护器3的设置位置加以限制。本领域技术人员可以根据实际情况,对保护器3的设置位置进行改变,能够起到相应的保护作用即可。Of course, the protector 3 may also be arranged only between the positive output end and the positive bus bar 4 or between the negative output end and the negative bus bar 5 . This embodiment is only for illustration, and does not limit the installation position of the protector 3 . Persons skilled in the art can change the setting position of the protector 3 according to the actual situation, and only need to be able to play a corresponding protective role.

保护器3可以为串联的断路器和熔断器。当然,保护器3还可以为单独设置的断路器或熔断器。The protector 3 may be a circuit breaker and a fuse connected in series. Of course, the protector 3 can also be a separate circuit breaker or fuse.

本发明通过设置保护器3,可以在储能电池模块2内部发生故障时,将电路断开,从而对储能电池模块2起到保护作用。并且,由于本申请的储能电池模块2相较于现有技术中的电池插箱为开放式的,在储能电池模块2内部发生故障时,可以对发生故障的储能电池单体1进行更换,无需对储能电池模块2整体进行更换。By setting the protector 3 in the present invention, when a fault occurs inside the energy storage battery module 2 , the circuit can be disconnected, so as to protect 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.
