本申请实施例
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
请参阅图1，本实施例涉及一种电池包，该电池包包括容纳箱以及设置在容纳箱内的多个电池模块1，多个电池模块1可以沿水平方向(箭头x所指的长度方向或者箭头y所指的宽度方向)排列，也可以沿竖直方向(箭头z所指方向)排列。
例如，容纳箱包括箱盖2以及箱体3，箱体3上设置有多个固定梁31。 另外，在其他实施例中，固定梁31可以设置在箱盖2上。本实施例中，固定梁31可以为箱体3的底部向上凸起的凸起梁或者单独作为零部件焊接在箱体3的底部。
电池包还包括压条4，压条4将电池模块1的两端压紧在固定梁31上，以将电池模块1固定在箱体3上。此时，通过压条4对电池模块1进行固定。
如图2所示，本实施例中，电池模块1包括上盖13、下盖14、防火构件17、灭火构件18以及两个电池单体排列结构10(也可以是大于两个的电池单体排列结构10)，其中一个电池单体排列结构10为第一电池单体排列结构101，另一个与第一电池单体排列结构101邻近的电池单体排列结构10为第二电池单体排列结构102。第一电池单体排列结构101与第二电池单体排列结构102均设置在上盖13与下盖14之间。
本实施例中，第一电池单体排列结构101与第二电池单体排列结构102均包括沿长度方向(箭头x所指的长度方向)排列的十四个电池单体11。当然，可根据需要调整电池单体11的数量、长度、高度、体积等。
在其他实施例中，电池模块1还可以只设置一个电池单体排列结构10，在电池单体排列结构10中，每个电池单体11均设置有防爆阀116，并且电池单体排列结构10的防爆阀116均面向防火构件17。
防火构件17竖直设置，第一电池单体排列结构101的防爆阀116和第二电池单体排列结构102的防爆阀116均面向防火构件17，防火构件17位于第一电池单体排列结构101的防爆阀116和第二电池单体排列结构102的防爆阀116之间。
此时，防火构件17设置在第一电池单体排列结构101的防爆阀116与第二电池单体排列结构102的防爆阀116之间，防火构件17将第一电池单体排列结构101的电池单体11与第二电池单体排列结构102的电池单体11隔开，避免已发生热失控的电池单体11引发与其邻近的电池单体11也发生热失控。
例如，灭火构件18设置在电池单体排列结构10的下方，灭火构件18设有可存储灭火液的流体通道。灭火构件18沿电池单体11的排列方向延伸，并且在长度方向上(箭头x所指的长度方向)与电池单体排列结构10的长度大致相同，当然也可以不相同。
本实施例中，灭火构件18设置在下盖14的下方，灭火构件18内可以设置有灭火液，一方面，在电池模块1正常工作时，灭火液可以作为冷却液，用于对电池单体排列结构10的电池单体11进行冷却；另一方面，在电池单体11发生热失控起火时，灭火构件18熔化并释放出灭火液以扑灭火焰，从而减小电池单体11热失控的危害。
如图3所示，在电池单体11(可以是第一电池单体排列结构101的电池单体11或第二电池单体排列结构102的电池单体11)发生热失控时，防爆阀116破裂并且喷出火焰与高温颗粒5。此时，电池单体11沿水平方向(箭头x所指的长度方向或者箭头y所指的宽度方向)喷出火焰与高温颗粒5，火焰与高温颗粒5被防火构件17挡下，高温颗粒5向下，烧穿下盖14以及灭火构件18，引发灭火构件18内的灭火液对高温颗粒5进行降温，从而减小电池单体11热失控的危害。
如图4以及图5所示，本实施例中，电池单体排列结构10包括多个电池单体11以及电连接多个电池单体11的多个汇流排12，多个电池单体11沿水平方向(箭头x所指的长度方向或者箭头y所指的宽度方向)排列。采集板15位于电池单体排列结构10的一侧且竖直设置，采集板15与电池单体排列结构10中的电池单体11相连接。
本实施例中，电池单体排列结构10还包括两个端板16，两个端板16分别位于多个电池单体11沿水平方向(箭头x所指的长度方向或者箭头y所指的宽度方向)排列的两端。
在具体实施例中，电池单体11的侧面涂胶与相邻的电池单体11粘接，多个电池单体11的两端设置端板16，形成电池单体排列结构10。电池单体 11与电池单体11之间通过汇流排12实现电连接，在电池单体排列结构10的汇流排12位置设置采集板15。将电池单体排列结构10平躺在下盖14上，电池单体排列结构10的下表面通过结构胶与下盖14相固定，电池单体排列结构10的上表面通过结构胶与上盖13相固定。
如图6所示，本实施例中，防火构件17包括防火构件主体171以及连接于防火构件主体171上端的第一延伸部172，第一延伸部172朝靠近第一电池单体排列结构101的方向延伸。
防火构件17还包括第二延伸部173，第二延伸部173连接于防火构件主体171上端，第二延伸部173朝靠近第二电池单体排列结构102的方向延伸。本实施例中，第一延伸部172朝靠近第一电池单体排列结构101的方向延伸以及第二延伸部173朝靠近第二电池单体排列结构102的方向延伸，并不局限于图6中，第一延伸部172与第二延伸部173沿水平方向(箭头x所指的长度方向或者箭头y所指的宽度方向)的实施例，第一延伸部172与第二延伸部173也可以向上向下倾斜延伸，或者弧形延伸等。
另外，本实施例中，防火构件17的形状为T形，通过T形的防火构件17与灭火构件18的配合，既可以防止火焰与高温颗粒5沿竖直方向(箭头z所指方向)向上喷出而危急乘客舱，又可以让火焰与高温颗粒5向下喷出而熔化灭火构件18进一步减小电池单体11热失控的危害。
例如，防火构件主体171、第一延伸部172以及第二延伸部173为一体式结构。如此，便于防火构件17的加工。
如图7所示，在其他实施例中，防火构件17包括防火构件主体171以及连接于防火构件主体171上端的第三延伸部174，第三延伸部174朝靠近电池单体11的方向延伸；和/或，防火构件17包括防火构件主体171以及连接于防火构件主体171下端的第四延伸部175，第四延伸部175朝靠近电池单体11的方向延伸。
在其他实施例中，防火构件17包括防火构件主体171、第三延伸部174 以及第四延伸部175，并不限制第三延伸部174以及第四延伸部175的位置以及形状，第三延伸部174用于防止火焰与高温颗粒5沿竖直方向(箭头z所指方向)向上喷出，第四延伸部17用于防止火焰与高温颗粒5沿竖直方向(箭头z所指方向)向下喷出，同样其到保护作用。只要可以将火焰与高温颗粒5挡下，防止火焰与高温颗粒5烧毁相邻电池单体，均在本实施例的保护范围内。
然而，需要说明的是，并不排除上述防火构件17出现各种第一延伸部172、第二延伸部173、第三延伸部174、第四延伸部175任意组合的可能性，实际应用中，可以根据实际的情况，调整防火构件17的形状样式，以取得最佳效果，防火构件17并不局限于本实施例中的形状样式。
另外，防火构件17的熔点大于或等于500℃，使得火焰不会熔化防火构件17，以起到防火的作用。具体的，本实施例中防火构件17采用云母板的材质，由于云母板的熔点很高(大约1723℃)，因此可以达到防火构件17的耐火需求，并且云母板具有优良的加工性能。但是，并不局限于云母板的实施例。
如图8所示，电池单体11包括电极组件111、电池壳体112、电极端子连接件113、盖板114以及电极端子115。电池壳体112可具有六面体形状或其他形状。电池壳体112具有容纳电极组件111和电解液的内部空间，并且电池壳体112具有开口。电极组件111容纳在电池壳体112内，盖板114覆盖开口，并用于将电极组件111封闭在电池壳体112内，电极组件111与电极端子115之间通过电极端子连接件113电连接。本实施例中，电极端子连接件113有两个，即分别为正极端子连接件113和负极端子连接件113。电池壳体112可以由例如铝、铝合金或塑料等材料制造。
电极组件111容纳于电池壳体112内，电极组件111包括第一极片1111、第二极片1112以及设置于第一极片1111和第二极片1112之间的隔膜1113。第一极片1111可以是正极片或负极片，第二极片1112与第一极片1111的极 性相反，相应地，第二极片1112为负极片或正极片。其中，隔膜1113是介于第一极片1111和第二极片1112之间的绝缘体。电极组件111可以是卷绕式结构(如图9)，也可以是叠片式结构(如图10)。
示例性地以第一极片1111为正极片，第二极片1112为负极片进行说明。同样地，在其他的实施例中，第一极片1111还可以为负极片，而第二极片1112为正极片。另外，正极活性物质被涂覆在正极片的涂覆区上，而负极活性物质被涂覆到负极片的涂覆区上。从涂覆区延伸出的未涂覆区则作为极耳，电极组件111包括两个极耳，即正极耳和负极耳，正极耳从正极片的涂覆区延伸出；负极耳从负极片的涂覆区延伸出。正极耳与正电极端子115之间通过正极端子连接件113电连接，负极耳与负电极端子115之间通过负极端子连接件113电连接。
电池壳体112大致为六面体结构，电池壳体112包括两个第一表面1121和两个第二表面1122，第一表面1121的面积大于第二表面1122的面积。在电池模块1中，每个电池单体11的两个第二表面1122沿水平方向(例如箭头x所指方向的长度方向)相互面对，每个电池单体11的两个第一表面1121沿竖直方向(箭头z所指方向)相互面对。
如图9以及图10所示，当电极组件111为卷绕式结构时，电极组件111为扁平状，并且电极组件111的外表面包括两个扁平面1114，两个扁平面1114均沿竖直方向(箭头z所指方向)相互面对，即扁平面1114与第一表面1121相互面对。电极组件111大致为六面体结构，扁平面1114大致平行于卷绕轴线且为面积最大的外表面。扁平面1114可以是相对平整的表面，并不要求是纯平面。
如图10所示，当电极组件111为叠片式结构时，第一极片1111、隔膜1113和第二极片1112沿竖直方向(箭头z所指方向)层叠，即第一极片1111的表面与第一表面1121相互面对。
电极组件111在充放电过程中不可避免的会沿第一极片1111的厚度方 向发生膨胀(在卷绕式结构的电极组件111中，沿垂直于扁平面1114的方向膨胀力最大；在叠片式结构的电极组件111中，沿第一极片1111和第二极片1112的堆叠方向膨胀力最大)。
本实施例中，电极组件111可以选用卷绕式结构或者叠片式结构。当电极组件111为卷绕式结构时，扁平面1114朝向竖直方向(箭头z所指方向)。当电极组件111为叠片式结构时，第一极片1111和第二极片1112沿竖直方向(箭头z所指方向)层叠。可见，电极组件111无论是采用卷绕式结构还是采用叠片式结构，电极组件111对电池壳体112施加最大膨胀力的方向都朝向竖直方向。
而现有技术中，电池模块1的电池单体11中，电极组件111对电池壳体112施加最大膨胀力的方向都是朝向水平方向，由于电池模块1沿水平方向的尺寸相比于竖直方向的尺寸大的多(例如，受到车辆的底盘高度尺寸限制，需要有更多的电池单体11沿水平方向堆叠，膨胀力累积大)，因此，现有电池模块1在水平方向上受到的膨胀力非常大，因此需要在电池模块1的水平方向两侧设置非常厚的端板以抵抗膨胀力，而端板加厚会降低电池模块1的能量密度。而本实施例中，电极组件111对电池壳体112施加最大膨胀力的方向是朝向竖直方向，而竖直方向上堆叠的电池单体11个数较少，因此相比于现有技术，可以大大减少电池模块1的最大膨胀力。
另外，由于电池单体11在充放电过程中还会在电池壳体112内部产生气体，产生的气体会对电池壳体112施加作用力，从而加剧电池壳体112向外膨胀。由于本申请的第一表面1121的面积大于第二表面1122的面积，并且电池单体11中的两个第一表面1121沿竖直方向相互面对，因此产生的气体对电池壳体112施加的最大作用力方向也是朝向竖直方向。相比于现有技术，进一步减少了电池模块1的最大膨胀力。
一个或多个实施例通过与之对应的附图中的图片进行示例性说明，这些示例性说明并不构成对实施例的限定，附图中具有相同参考数字标号的元 件表示为类似的元件，除非有特别申明，附图中的图不构成比例限制。
