目前,多数动力电池的组成结构主要是:通过电芯框架承载单体电池,以多个单体电池组成电芯组,再将多个电芯组组合成电芯模组,在电芯模组两端连接端板,两侧设置侧箱板,以实现承力,电芯模组上方设置电气隔离板,汇流排设置于电气隔离板上并连接线束,上盖盖设于电气隔离板上部并连接于端板、侧箱板等,由此组成电池包。这种组成方式内部构件繁多,不仅装配复杂,还占用较大的电池箱内部空间,体积空间利用率较低,并且优化空间小,难度大。与之相比,本申请实施例的电池模组及电池包可通过安装板对单体电池进行定位,并可采用单体电池和安装板直接连接电池包箱体形成电池包(CTP)的结构,相比于上述方式,能够省去一些结构件,从而释放更多的内部安装空间以供单体电池的安装,有助于提高内部空间利用率或者减小电池尺寸,并且简化装配,能够在一定程度上降低成本。
图1为本申请一个实施例的电池包的立体结构示意图,图2为图1所示实施例的电池包的部分结构分解示意图,参考图1和图2,本申请实施例的电池包,包括箱体300和电池模组200电池模组200包括多个单体电池100和用于定位固定各单体电池100的安装板230。单体电池100成排地设置于安装板230之间。箱体300包括下箱体320和箱盖310,下箱体320包括侧箱板322和底板321,侧箱板322和底板321围合成安装腔330,电池模组200置于安装腔330内,安装板230连接于箱体,箱盖310盖设于安装腔330的上部并可拆卸地连接于侧箱板322。
图3为本申请一个实施例的电池模组的部分结构分解示意图,图4为本申请一个实施例的电池模组省去单体电池的结构示意图,参考图3和图4,本申请实施例的电池模组200包括两个相对设置的安装板230和若干绝缘插板260,多个单体电池100成排地设置于安装板230之间。图5为本申请另一个实施例中的安装板的结构示意图,图6为本申请一个实施例中的安装板、绝缘插板和单体电池的分解示意图,参考图5和图6,在一些实施例的电池模组中,在安装板230沿单体电池100的排布方向的两端中的至少一端设置有绝缘插板260,可在安装板230沿单体电池100排布方向的一端设置有绝缘插板260;或者,在安装板230沿单体电池100排布方向的两端均设置有绝缘插板260。绝缘插板260连接于安装板230,电池模组200装入电池包的箱体后,位于安装板230端部的绝缘插板260用于在单体电池100的排布方向上抵持于单体电池100和电池包的箱体300之间。因此,电池模组200可以直接装配于电池包的箱体中,可由绝缘插板260抵抗单体电池100的膨胀力并将力传递至箱体300,省去了将单体电池100组装成模组的结构件,从而简化结构和装配,并且,结构件的减少能够提供更多的箱体内部安装空间,有助于提高内部空间利用率,从而提高电池包的体积能量密度。
在一些实施例的电池模组中,在任意一个或多个位置的单体电池100之间设置有绝缘插板260,绝缘插板260具体的设置位置可以根据实际装配需求进行合理配置,例如:位于安装板230的中部的 位置的单体电池100之间设置有绝缘插板260,或者每间隔一定数量的单体电池100之间设置一件绝缘插板260。该绝缘插板260可在单体电池100的排布方向上抵持于单体电池100之间,可对单体电池100具有一定的预紧作用,能一定程度地抵抗单体电池100沿排布方向的膨胀力,适用于单体电池100的数量较多、排布长度较大的电池包。
另外,在一些其他实施例的电池模组中,在安装板230沿单体电池100的排布方向的两端中的至少一端设置有绝缘插板260,并且,在任意一个或多个位置的单体电池100之间也设置有绝缘插板260,与上述实施例同理,单体电池100沿排布方向的膨胀力可由设置于安装板230端部的绝缘插板260抵抗并将力传递至箱体300,设置于单体电池100之间的绝缘插板260可在单体电池100的排布方向上抵持于单体电池100之间,可对单体电池100具有一定的预紧作用,从而有助于单体电池排布方向的膨胀力的传递,从而提高电池模组的稳定性。
在上述实施例中,绝缘插板260相对于单体电池100排布方向的一侧或两侧可以设置凸台,凸台能够增大绝缘插板260沿单体电池100排布方向的厚度,从而能够更好地对单体电池进行抵持和传力。具体实施当中,凸台凸起的高度可以根据实际的装配需求(如装配间隙)进行合理配置。图5为本申请另一个实施例的安装板的结构示意图,参考图5,与上述实施例相比,本实施例的电池模组200中,两件安装板230的端部的一端还可以设置连接板250,另一端采用上述实施例的方式设置绝缘插板260,其中,连接板250可以通过插接的方式连接于安装板230,或者通过连接件可拆卸地与安装板230连接,或者通过焊接、铆接等与安装板230连接为一体,或者连接板250与安装板230通过一体成型工艺成型为一体。
图6为本申请一个实施例的安装板、绝缘插板和单体电池的分解示意图,图7为本申请一个实施例中的绝缘插板的结构示意图,参考图6和图7,在一些实施例的电池模组200中,安装板230上沿单体电池100的排布方向的两端均设置有绝缘插板260,绝缘插板260的两侧可以抵持于位于端部的单体电池100和箱体300之间,由此,多个单体电池100组成的电池组件沿单体电池100的排布方向的膨胀力,能够通过绝缘插板260直接传递到箱体300上,即实现了单体电池100直接向箱体300传力的方式。
常规电池模组中,单体电池之间没有定位结构,需要通过两端的端板从电池两端进行预紧从而实现单体电池的固定,与常规电池模组相比,而本申请的电池模组,单体电池100的排布方向的膨胀力,能够通过绝缘插板260直接传递到箱体300上,通过箱体300抵抗膨胀力,省去了端板及其预紧连接结构,简化了装配。
将电池模组200装入箱体300中后,安装板230两端的单体电池100与箱体300侧箱板322之间存在一定的间隙,然后在安装板230两端与箱体300之间插入绝缘插板260,绝缘插板260能够对单体电池100进行进一步顶紧定位,并且绝缘插板260和箱体300的内壁之间可以直接抵持,由此绝缘插板260能够抵持于单体电池100和箱体300内壁之间,实现单体电池排布方向上力的传递。或者,绝缘插板260和箱体300的内壁之间可以具有一定间隙,在间隙内还可设置灌封胶,灌封胶能够吸收 单体电池排布方向的公差,将膨胀力通过灌封胶传至箱体300。可在两者之间设置“U”型泡棉280围成胶槽,向胶槽内注入灌封胶,灌封胶的注入量可根据绝缘插板260和箱体300侧箱板322之间的距离进行调整。另外,为使绝缘插板260具有较佳的传力作用,绝缘插板260朝向箱体300侧箱板322的一侧中部可以设置凸台261,从而能够更稳定地抵持箱体300的侧箱板322。
同理,根据电池包内部结构和实际的安装需求,也可以仅在安装板230沿单体电池100排布方向的其中一端设置绝缘插板260,安装板230的另一端抵持于箱体300的侧箱板322,同样能够通过安装板230和绝缘插板260将单体电池100的排布方向的膨胀力传递至箱体300,于绝缘插板260的一侧实现公差的吸收。另外,当所需组装的单体电池100数量较多,排布距离较长时,可以设置多对安装板230对所需组装的单体电池100进行固定,相邻的一对安装板230之间可以相互顶紧,并于顶紧处设置绝缘插板260,由此,安装板230顶紧处的单体电池100之间可以通过设置该绝缘插板260进行抵持,实现安装板230和单体电池的进一步紧固。同理,根据单体电池100间的紧固要求,也可以在安装板230的任意一个或多个位置的单体电池100之间设置绝缘插板260,实现单体电池100之间进一步的紧固。
根据上述实施例,图8为本申请另一个实施例的安装板的结构示意图,图9为图8中的I处局部放大图,参考图8和图9,安装板230上所需设置绝缘插板260的位置,可以设置插板插槽240,由此绝缘插板260可以采用插接的方式连接于安装板230,连接方式简单,有助于快速装配。具体来说,参考图9,以安装板230端部设置绝缘插板260的方案为例,两件安装板230相对的位置,有开口相对的开槽,形成上述的插板插槽240,两个开槽分别用于容纳绝缘插板260对应的两侧边沿,因此,将绝缘插板260对应于两开槽的边沿插入开槽内,即可实现插接安装。
图8为本申请另一个实施例的安装板的结构示意图,图9为图8中的I处局部放大图,参考图8和图9,在上述实施例中,安装板230之间沿单体电池100的排布方向具有多个插槽210,各单体电池100分别位设置于各插槽210中。通过插槽210实现单体电池100的定位和安装,不需要另外设置各单体电池100的固定框架,能够在一定程度上节省电池模组内部空间。
在一些实施例中,安装板230相互朝向的一侧沿单体电池100的排列方向设置有多个凹槽237,两个安装板230上的凹槽237的位置相互对应,对应的两个凹槽237组成用于容置单体电池100且对单体电池100的两侧侧部进行限位的插槽210。两个安装板230组合形成的围框,相对于单体电池的顶部120和底部的两侧均设为敞口,因此,单体电池的顶部120构件能够露出于插槽210的外部,以便电气连接,单体电池的底部130能够与箱体300的底板321连接。
两个安装板230可以采用分体式结构,装配时,可将两件安装板230从两侧包夹于单体电池100的两侧,从而将单体电池100装入插槽210,再安装绝缘插板260,然后再装入箱体300中。两个安装板230也可以通过连接板连接为一个整体,单体电池100从上侧或下侧插入插槽210中,再安装绝缘插板260。实际装配时,可根据具体的安装板230的结构、单体电池100与安装板230的固定方式合理调整装配方式。
在一些实施例中,参考图8和图9,各安装板230包括板体231和隔条232,隔条232沿单体电池100的排布方向间隔设置于板体231的相互朝向的一侧,安装板230对应于单体电池100的两侧的底部设置有底托233,底托233向板体231的内侧延伸至隔条232的下方,从而能够自单体电池的侧部140的下方承托单体电池的底部130。在安装板230对应于单体电池的顶部120设置有第一安装台234,第一安装台234向板体231的内侧延伸至隔条232的上方,从而能够自单体电池的侧部140的上方限位单体电池的顶部120,由此,相邻的隔条232之间以及第一安装台234、底托233共同围合形成上述的用于对单体电池的侧部140、顶部120和底部130进行限位的凹槽237。装配时,只需使两安装板230上的凹槽237对应于单体电池100的两侧,然后将安装板230夹于单体电池100的两侧,即可将单体电池100定位于两件安装板230上,然后整体置入电池包箱体中。在本实施例中,两件安装板230为分体结构,可分别从单体电池100的两侧安装,单体电池100的两侧的顶部和底部被限位于凹槽237中。
根据本申请的一些实施例,参考图2、图10和图11,安装板230相互背离的外壁设置有向外凸出的挡肩270,挡肩270可以是沿单体电池100的排布方向延伸成一整条的长条结构,也可以是多个沿单体电池100的排布方向排列的凸台结构。箱体300的侧箱板322上设置有定位台350,电池模组200置于箱体300中后,挡肩270置于定位台350上,并且挡肩270的外侧边沿抵持于侧箱板322的内壁,由此,单体电池100通过安装板230的外壁以及挡肩270实现加速力向箱体300的传递,实现了单体电池100直接向箱体300传力的方式。
另外,单体电池的底部130与箱体300底部连接之后,电池模组200沿长度方向的弯曲和扭转受箱体300底板321限制,增大了电池模组200长度方向的截面惯性矩,有效解决了电池模组在长度方向的模态小的问题。
在一些实施例中,安装板230上对应于各单体电池100的位置还设置有汇流排220,例如,汇流排220可以连接于第一安装台234,汇流排220电连接于插槽210内的单体电池100的极柱。由此,电池包还可省去常规结构中用于配置汇流排的电气隔离板,从而进一步减少电池包内部结构件,实现结构和装配的简化,并能够在一定程度上减少内部空间的占用,有助于提高电池包的内部空间利用率。
上述实施例的电池包还包括数据采集系统400、电池控制单元500及配电盒600,数据采集系统400电连接于单体电池100,以实现单体电池100的相关数据采集,电池控制单元500电连接于数据采集系统400和配电盒600,实现电池的整体调控,配电盒600还连接有用于外部连接的连接器(包括高压连机器、低压连接器等)。箱体300上位于单体电池100排布方向的一端还设置有用于容纳配电盒600的空腔,该空腔与用于安装电池模组200的安装腔330之间通过一侧箱板322隔开。本申请实施例的电池包中,可采用已知技术中常规应用于电池包的数据采集系统400、电池控制单元500及配电盒600,其控制原理在此不做赘述。
在一些实施例的电池包中,下箱体320设置有两个安装腔330,各安装腔330中分别采用上述实施例的装配方式装配有电池模组200,形成具有两组电池模组200的电池包。其中,下箱体320可采 用多个侧箱板322组合连接而成,适用于也可以通过一体成型工艺成型为一体。另外,箱盖310和下箱体320之间还可以设置密封件340,从而有效隔绝外部水汽。
在一些实施例的电池包中,底板321上或者底板321的内部设置有用于通入冷却液的流道323,因此,通过冷却液对底板321的冷却,同时能够对连接于底板321的单体电池100进行散热,实现了单体电池100直接对箱体300传热的方式,省去了中间传热构件,既实现了热量的高效传递,又能够释放更多的内部空间,从而有助于提高电池内部的空间利用率。
由上述可知,本申请实施例的电池包,实现了单体电池与箱体的直接传力装配,与通过常规的电芯模组组装形成电池的方案相比,减少了多个结构件,例如减少了电气隔离板、电芯模组端板和模组侧箱板,由此简化了装配工艺,有助于降低成本。并且,结构件的减少能够释放较多的内部空间,因此,在体积不变的情况下可以布置更多的单体电池,提高电池能量密度,或者在单体电池数量不变的情况下,减小电池的整体体积,从而满足实际使用时的包络要求。本申请的电池包改变了单体电池的传力方式,有效提高了力学性能,且易于装配,在满足功能及安全要求的同时也能降低成本。
上面结合附图对本申请实施例作了详细说明,但是本申请不限于上述实施例,在所属技术领域普通技术人员所具备的知识范围内,还可以在不脱离本申请宗旨的前提下作出各种变化。此外,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
