背景技术Background technique
用于将电池系统内的电池模块电路连接的、具有螺栓触头和插接触头的电池系统中的电池模块的连接装置是已知的。在电池系统中连接电池模块时,带有螺栓触头的连接设备不能提供接触保护。出于该原因,自模块电压高于60V起,只能由受过培训的人员进行电池模块的安装和拆卸。此外,螺栓还必须以一定的预紧力拧紧。但是,预紧力可能会随着时间的流逝而减少。这又可能会导致连接装置中接触电阻的增大。具有插接触头的连接设备比带螺栓触头的连接设备具有更大的接触电阻。这会导致插接触头中产生额外的电热损耗。在相关情况下,这可能导致电池模块内的额外热量,并导致电池模块更快地老化。如果将这样的电池模块用在电动车辆中,则可能会随着电池模块的寿命而减小电动车辆的行驶范围。Connecting devices for battery modules in a battery system with screw contacts and plug contacts for the electrical connection of battery modules in a battery system are known. Connection devices with screw contacts do not provide contact protection when connecting battery modules in battery systems. For this reason, since the module voltage is higher than 60V, the installation and removal of battery modules must only be carried out by trained personnel. In addition, the bolts must also be tightened with a certain preload. However, the preload may decrease over time. This in turn may lead to an increase in contact resistance in the connection device. A connection device with plug contacts has a higher contact resistance than a connection device with screw contacts. This leads to additional electrical and thermal losses in the plug contacts. Where relevant, this can lead to additional heat within the battery module and cause the battery module to age more quickly. If such a battery module is used in an electric vehicle, the driving range of the electric vehicle may be reduced with the life of the battery module.

具体实施方式Detailed ways
在不同的附图中,本发明的相同特征总是具有相同的附图标记,因此它们通常只被描述一次。In the different drawings, the same features of the invention are always given the same reference numerals, so that they are usually only described once.
图1示出了已知的电池系统中电池模块的连接装置的问题,该电池系统具有螺栓触头100*和插头触头100**,用于机械地固定和电路连接电池系统中的电池模块。带有螺栓触头100*的连接装置虽然具有相对较高的预紧力F*和相对较低的电阻R*,但它们在操作螺栓触头100*时不提供任何接触保护。带有插头触头100**的连接装置可以相对安全地操作,但它们的电阻R*比带有螺栓触头100*的连接装置明显更大。FIG. 1 shows a problem with the connection arrangement of battery modules in a known battery system having
图2至5示出了根据本发明的电池模块1的连接装置100,其至少部分地克服了上述缺点,并且有利地结合了螺栓触头100*和插头触头100**的优点。根据本发明的连接装置100具有以下单元:用于将电池模块1机械地固定在电池系统S内的电池模块1的固定单元10,例如,固定在(出于简单的原因而未示出的)电池系统S的电池壳上,以及用于电路连接或接触电池模块1的接触单元20,例如,与电池系统的另一电池模块连接或接触。在本发明的范围内,使用单独的接触单元20,其可以与固定单元10空间上间隔地布置在电池模块1上(参见图2和5)。Figures 2 to 5 show a
在连接装置100中,本发明提供一种力偏转装置30,以在固定单元10和接触单元20之间建立机械的作用连接,如在图2中借助于箭头F所示。力偏转装置30获取固定单元10上的固定力F,并将该固定力F(必要时是加强的)传送到接触单元20,用以提高固定力F(被电连接的部件21、23通过固定力F进行相互接触),从而降低接触单元20处的电阻。In the
按照本发明的电池模块1具有多个蓄电池单池并且在高压应用(例如电动车)中被使用。按照本发明的电池模块1能够在模块化构造的电池系统S的框架内构建,所述电池系统S可以具有如本发明电池模块1那样的另外的电池模块。The
借助于固定单元10将电池模块1机械地固定在电池系统S的电池壳体上。为此,固定单元10可以具有螺栓触头。借助于接触单元20在电池模块1上提供电连接,以将电池模块1在电池系统S内进行电路连接,特别是为了将电池模块1与电池系统S的另一电池模块电连接。为此,接触单元20可以具有插塞触头,如图4示意性所示。The
参照图2和图3,固定单元10具有固定元件11,该固定元件优选地为密配螺栓的形式,用于形状配合和/或摩擦配合地固定在电池模块1的对应固定元件101(例如以螺纹孔的形式)上(参见图2和5)。借助于穿过对应固定元件101的密配螺栓能够将电池模块1与未详细示出的电池系统S的壳体螺栓连接。2 and 3 , the fixing
如图2示出,固定单元10具有可移动的、即能够相对电池模块1移动地被支承的受力元件12(尤其呈优选弹性的或可延展的垫片的形式),其优选通过承接固定元件11而被压开并展开,用于建立固定力F。优选地,固定力F可以经由力偏转装置30传递到接触单元20。As shown in FIG. 2 , the fixing
此外如图2所示,可移动的受力元件12具有两个第一弹簧元件F1和两个第二弹簧元件F2,通过它们,可移动的受力元件12连接到力偏转装置30,并且能够优选在两侧被支撑在电池模块1上。Furthermore, as shown in FIG. 2 , the movable force-receiving
可移动的受力元件12被布置在对应固定元件101周围,例如被布置在螺纹孔周围。通过两个第一弹簧元件F1,可移动的受力元件12连接到力偏转装置30的两个把手33。力偏转装置30的两个把手33通过两个第二弹簧元件F2支撑在电池模块1上,例如支撑在模块壳体上。为此,可以在电池模块1上、例如在模块壳体上设置支撑件102。The movable force-receiving
如图3所示,优选地将密配螺栓用作固定元件11。通过将密配螺栓插入可移动的受力元件12内和螺纹孔内,在可移动的受力元件12上产生固定力F,该固定力F将可移动的受力元件12压开并张紧。由此,力偏转装置30的相关联的把手33同时被向外按压。As shown in FIG. 3 , a close-fit screw is preferably used as the fixing
把手33的另外的端部例如通过两个夹钳35连接到接触单元20。两个夹钳35压在接触单元20的侧表面24上,并在那将固定力F引入到接触单元20中。为此,可以在力偏转装置30的两个夹钳35上设置两个压力板36,以便能够将力均匀地引入到接触单元20中。接触单元20的侧表面24被压在一起,使得插接套筒22、特别是插接套筒22内的弹簧弹性的夹紧元件23和插销21之间的接触力增加。The other end of the
换句话说,接触单元20可以具有插接连接器,如图4所示。这具有的优点在于,插接连接器可以设计成具有小的接触力,由此显着降低了连接装置100的价格。力偏转装置30也显著降低了连接器内的接触电阻。In other words, the
如上所述,接触单元20、特别是插接连接器可以具有插销21和/或插接套筒22,用于尤其在电池模块1与电池系统S的另外的电池模块之间建立电接触。在本发明的范畴中可以想到的是,插接连接器的元件,插销21或插接套筒22可以电连接到电池模块1的模块端子T1、T2,其中插接连接器的另外的互补的元件能够与电缆K相连,其能够引导至电池系统S的另外的电池模块。As mentioned above, the
如图4还示出,接触单元20,特别是插接连接器可以在插销周围具有至少一个(例如在插接套筒22内的)弹簧弹性的夹紧元件23(特别是呈弹簧弹性的夹子的形式并优选地具有一个或多个薄片)用于在插接套筒22中优选无缝隙地夹紧插销21。As also shown in FIG. 4 , the
图2进一步示出,力偏转装置30可以具有至少一个力转向元件31,特别是以钳子的形式。此外,力转向元件31、特别是钳子可以具有两个、优选为两侧的杠杆32和关节34。杠杆32可以用来增加固定力F。关节34可以用于将力偏转装置30支撑在电池模块1上。FIG. 2 further shows that the
相应构造的电池模块1,具有至少一个这样的电池模块1的模块化构造的电池系统S和用于在电池系统S中连接这样的电池模块1的相应方法代表了本发明的其他主题。A correspondingly constructed
