技术领域
本申请涉及电池技术领域，尤其涉及一种温控组件及电池包。
背景技术
电池包通常包括成组在一起的多个电池。在成组技术中，除了保证结构自身强度和性能外，还需要考虑结构对于电池寿命的影响，其中温度和膨胀力对于电池寿命影响很大，所以在设计时必须考虑热管理和膨胀力设计。
在热管理设计方面：目前主要有水冷和风冷两种方式。其中，由于水冷方式的成本较高，因而电池包普遍采用风冷方式进行散热。
在膨胀力设计方面：电池包在充放电过程中，电池会逐渐产生膨胀、且与固定结构产生相互作用力(即膨胀力)。其中，适当的膨胀力会有益于电池自身反应，但是过大的膨胀力会使得电池受压过大而发生析锂现象，甚至产生不可逆的容量损失，从而极大地降低了电池的寿命。
为了缓解膨胀力，目前主要有以下几种形式：(1)电池之间直接贴紧、加强外部结构，以直接抵抗膨胀力，这种方式的不足之处在于：当电池容量和电池成组串数逐渐提升时，电池成组后的膨胀力会越来越大，从而降低了电池使用寿命；(2)电池间增加缓冲垫等结构，其通过材料自身伸缩特性来吸收膨胀力，从而降低成组后的膨胀力，这种方式的不足之处在于：电池大面紧贴缓冲垫，只能采用电池侧面和底部散热，由此降低了散热效率；(3)电池与电池隔开，中间空出间隙，以使得电池自由膨胀，这种方式的不足之处在于：电池初始时为自由膨胀，在无压力下容易反应不充分，降低了使用寿命，同时若电池膨胀量较大、预留间隙过大时，影响成组体积。
申请内容
鉴于背景技术中存在的问题，本申请的目的在于提供一种温控组件及电池包，当温控组件应用于电池包中时，温控组件不仅能够对电池进行热管理，还能够吸收电池产生的膨胀力，从而降低了电池在膨胀力作用下产生的变形，极大地提高了电池的使用寿命。
为了实现上述目的，本申请第一方面提供了一种温控组件，其包括：第一侧板；第二侧板，沿纵向与第一侧板相对设置，且第二侧板连接于第一侧板并与第一侧板一起形成有空腔；以及第一缓冲板，设置于第二侧板与第一侧板之间并连接于第二侧板和第一侧板，以将所述空腔划分为多个通道，且第一缓冲板的至少部分从第一侧板朝向第二侧板倾斜延伸。
本申请第二方面提供了一种电池包，其包括多个电池以及上述所述的温控组件，所述多个电池包括第一电池和第二电池，温控组件设置于第一电池与第二电池之间。
本申请的有益效果如下：
本申请的电池包中，当外部空气流经温控组件的通道时，即可实现对电池的散热处理。且在电池包的使用过程中，电池会产生膨胀力，此时相邻两个电池的膨胀力分别挤压第一侧板和第二侧板、而第一侧板和第二侧板将膨胀力传递给第一缓冲板。由于第一缓冲板的至少部分从第一侧板朝向第二侧板倾斜延伸，从而使得经由第一侧板和第二侧板传递给第一缓冲板的膨胀力大大减小，由此延长了温控组件的使用寿命。并且，由于第一缓冲板倾斜延伸的所述至少部分在膨胀力的作用下更容易产生弯曲变形，从而使得温控组件能够及时吸收电池的膨胀力，由此极大地提高了电池的使用寿命。

参照图1至图31，本申请的电池包包括温控组件1、多个电池2、下箱体3、风道组件4、风机5、扎带6、上箱盖7、端板8、安装面板9以及线束隔离板10。
参照图2、图9、图10、图24和图25，所述多个电池2包括第一电池2A和第二电池2B，温控组件1设置于第一电池2A与第二电池2B之间。进一步地，第一电池2A和第二电池2B在数量上可均为多个、多个第一电池2A和多个第二电池2B在纵向Y上交替排列，且每相邻的第一电池2A和第二电池2B之间可均设置温控组件1。
为了保证温控组件1的强度以及导热性，温控组件1可由金属材料制成，如铝型材。
参照图3至图8、图11至图15、图17至图20、图22、图26至图30，温控组件1可包括第一侧板11、第二侧板12、第一缓冲板13、第一连接板15以及第二连接板16。其中，第一侧板11、第二侧板12、第一缓冲板13、第一连接板15以及第二连接板16可采用挤铝工艺一体成型。
第一侧板11沿纵向Y与第二侧板12相对设置，且第二侧板12通过第一连接板15和第二连接板16连接于第一侧板11。其中，第一侧板11和第二侧板12直接面向对应电池2的大面设置，当外部空气流经温控组件1时，即可实现对电池2的散热处理。
第一连接板15连接第一侧板11的一端和第二侧板12的一端、第二连接板16连接第一侧板11的另一端和第二侧板12的另一端，由此第一侧板11、第二侧板12、第一连接板15以及第二连接板16一起形成带有空腔的围框结构。
第一缓冲板13设置于第二侧板12与第一侧板11之间并连接于第二侧板12和第一侧板11，以将所述空腔划分为多个通道F，且第一缓冲板13的至少部分从第一侧板11朝向第二侧板12倾斜延伸。其中，第一缓冲板13在数量上可为多个，所述多个第一缓冲板13沿上下方向Z间隔设置， 从而将所述空腔划分为多个通道F。
在电池包的使用过程中，电池2会产生膨胀力，此时相邻两个电池2(即第一电池2A和第二电池2B)的膨胀力分别挤压第一侧板11和第二侧板12、而第一侧板11和第二侧板12将膨胀力传递给第一缓冲板13。由于第一缓冲板13的至少部分从第一侧板11朝向第二侧板12倾斜延伸，从而使得经由第一侧板11和第二侧板12传递给第一缓冲板13的膨胀力大大减小，由此延长了温控组件1的使用寿命。并且，由于第一缓冲板13倾斜延伸的所述至少部分在膨胀力的作用下更容易产生弯曲变形，从而使得温控组件1能够及时吸收电池2的膨胀力，由此极大地提高了电池2的使用寿命。
由于第一缓冲板13的延伸方向(即第一缓冲板13的所述至少部分的延伸方向)与第一侧板11形成的夹角大小以及与第二侧板12形成的夹角大小，决定了经由第一侧板11和第二侧板12传递给第一缓冲板13的膨胀力大小，若第一缓冲板13受到的膨胀力过大，则会压断第一缓冲板13。因此，为了防止第一缓冲板13被过大的膨胀力压断，优选地，参照图8、图15、图20，第一缓冲板13的延伸方向与第一侧板11形成的锐角θ 1不大于45°(第一缓冲板13与第二侧板12形成的锐角等于第一缓冲板13与第一侧板11形成的锐角)。
下面基于第一缓冲板13的设置方式，详细说明温控组件1的几种具体结构。
在第一实施例中(未示出)，温控组件1的第一侧板11与第二侧板12之间仅设置有第一缓冲板13，第一缓冲板13整体从第一侧板11朝向第二侧板12倾斜延伸而成。具体地，第一缓冲板13整体可沿从第一侧板11朝向第二侧板12倾斜向上的方向延伸而成；或者，第一缓冲板13整体可沿从第一侧板11朝向第二侧板12倾斜向下的方向延伸而成。
在第一实施例中，第一缓冲板13可形成为平板状结构或者弧形板状结构。第一缓冲板13可形成为厚度均匀的结构；或者，第一缓冲板13可形成为中间厚两端薄的结构；或者，第一缓冲板13可形成为中间薄两端厚的结构。
在第二实施例中，参照图3和图4，温控组件1的第一侧板11与第二侧板12之间仅设置有第一缓冲板13，此时第一缓冲板13可形成为波浪状 结构(也可称为瓦楞板状结构)。换句话说，第一缓冲板13沿从第一侧板11朝向第二侧板12倾斜向上的方向以及从第一侧板11朝向第二侧板12倾斜向下的方向交替延伸而成。
这种结构的第一缓冲板13形成有一个个凸起，且各凸起形成为弧形状结构。基于各凸起的形状结构，使得第一缓冲板13具有足够的弯曲变形空间，从而使得温控组件1能够及时吸收电池2的膨胀力，极大地提高了电池2的使用寿命。
在第三实施例中，参照图5至图8、图11、图13、图14、图18、图19、图26、图28、图29，第一缓冲板13整体从第一侧板11朝向第二侧板12倾斜向上延伸而成，温控组件1还包括第二缓冲板14。第二缓冲板14设置于第二侧板12与第一侧板11之间并连接于第二侧板12和第一侧板11，且第二缓冲板14从第一侧板11朝向第二侧板12倾斜向下延伸而成。第二缓冲板14用于与第一缓冲板13一起吸收电池2的膨胀力，由此极大地提高了电池2的使用寿命。
第二缓冲板14在数量上可为多个，所述多个第二缓冲板14沿上下方向Z间隔设置，以与第一缓冲板13一起将所述空腔划分为多个通道F。
由于第二缓冲板14的延伸方向与第一侧板11形成的夹角大小以及与第二侧板12形成的夹角大小，决定了经由第一侧板11和第二侧板12传递给第二缓冲板14的膨胀力大小，若第二缓冲板14受到的膨胀力过大，则会压断第二缓冲板14。因此，为了防止第二缓冲板14被过大的膨胀力压断，优选地，参照图8、图20、图30，第二缓冲板14的延伸方向与第一侧板11形成的锐角θ 2不大于45°(第二缓冲板14与第二侧板12形成的锐角等于第二缓冲板14与第一侧板11形成的锐角)。
参照图5至图8、图11、图13、图14、图18、图19、图26、图28、图29，第二缓冲板14沿上下方向Z与第一缓冲板13间隔设置且第一缓冲板13与第二缓冲板14交错布置，此时第一缓冲板13和第二缓冲板14形成为“八”字状结构。这种“八”字状结构，保证了温控组件1的结构稳定性，提高了温控组件1的结构强度。
参照图6、图11，第二缓冲板14直接连接于第一缓冲板13，且第一缓冲板13和第二缓冲板14与第一侧板11的对应部分形成三角状结构、第一缓冲板13和第二缓冲板14与第二侧板12的对应部分也形成三角状结 构。这种三角状结构，保证了温控组件1的结构稳定性，提高了温控组件1的结构强度。
参照图7，第二缓冲板14直接连接于第一缓冲板13，且第一缓冲板13与第二缓冲板14形成为拱形结构。这种拱形结构，保证了温控组件1的结构稳定性，提高了温控组件1的结构强度。
在第三实施例中，第一缓冲板13和第二缓冲板14可形成为厚度均匀的结构(如图6和图7所示)。或者，第一缓冲板13和第二缓冲板14可形成为中间厚两端薄的结构。或者，第一缓冲板13和第二缓冲板14可形成为中间薄两端厚的结构(如图5和图8所示)。第一缓冲板13和第二缓冲板14可形成为平板状结构(如图6所示)或者弧形板状结构(如图7所示)。
参照图12、图15、图16、图17、图20、图21、图22，本申请的电池包中，第一侧板11可设置有：第一限位凸起111，沿纵向Y朝向第二侧板12延伸并位于对应的通道F内，且第一限位凸起111处于第一缓冲板13在第一侧板11上的投影区域内。第二侧板12可设置有：第二限位凸起121，沿纵向Y朝向第一侧板11延伸并位于对应的通道F内，且第二限位凸起121处于第一缓冲板13在第二侧板12上的投影区域内。
在第一缓冲板13的弯曲变形过程中，由于第一限位凸起111和第二限位凸起121的设置，第一缓冲板13最终会抵靠到第一限位凸起111和第二限位凸起121上(如图16和图21所示)，从而使得第一缓冲板13的弯曲变形受到限制，进而使得对应的通道F依然具有满足热管理要求的通风空间，由此提高了温控组件1对电池2的热管理性能，从而极大地提高电池2的使用寿命。
第一限位凸起111与第二限位凸起121相对设置。具体地，第一限位凸起111与第二限位凸起121在纵向Y上齐平设置；或者，第一限位凸起111与第二限位凸起121在上下方向Z上错位设置。
为了保证第一侧板11和第二侧板12的抗挤压强度，第一限位凸起111和第二限位凸起121的数量可根据强度要求进行选择性设置。具体地，参照图18至图22，第一侧板11的第一限位凸起111在数量上可为一个。参照图12至图17，第一限位凸起111在数量上可为多个。类似地，第二限位凸起121在数量上也可为一个(如图18至图22所示)或多个(如图12 至图17所示)。
第一缓冲板13的长度为L并具有第一端部131和第二端部132，且所述第一端部131连接于第一侧板11、所述第二端部132连接于第二侧板12。
当第一限位凸起111在数量上为一个时(如图20所示)，第一限位凸起111与第一端部131在上下方向Z上的距离为a1(即第一端部131靠近第一限位凸起111的边缘与第一限位凸起111靠近第一端部131的边缘之间的距离)，且0＜a 1≤L/2。当第一限位凸起111在数量上为多个时(如图15所示)，所述多个第一限位凸起111与第一端部131在上下方向Z上的距离为a 2(即第一端部131靠近第一限位凸起111的边缘与距离第一端部131最近的一个第一限位凸起111的边缘之间的距离)，且0＜a 2≤L/2。
这里，参数a 1(或a 2)的大小决定了第一限位凸起111在第一侧板11上的设置位置，为了保证第一限位凸起111对第一缓冲板13的限位作用，第一限位凸起111需要设置在第一缓冲板13最大自由变形圆弧与第一侧板11相切位置与第一端部131之间，即0＜a 1≤L/2(或者0＜a 2≤L/2)。而当a 1＞L/2(或者a 2＞L/2)时，由于第一缓冲板13的弯曲变形程度有限，第一限位凸起111很难甚至无法对第一缓冲板13的弯曲变形起到限制作用。
当第二限位凸起121在数量上为一个时(如图22所示)，第二限位凸起121与第二端部132在上下方向Z上的距离为b 1(即第二端部132靠近第二限位凸起121的边缘与第二限位凸起121靠近第二端部132的边缘之间的距离)，且0＜b 1≤L/2。当第二限位凸起121在数量上为多个时(如图17所示)，所述多个第二限位凸起121与第二端部132在上下方向Z上的距离为b 2(即第二端部132靠近第二限位凸起121的边缘与距离第二端部132最近的一个第二限位凸起121的边缘之间的距离)，且0＜b 2≤L/2。
这里，参数b 1(或b 2)的大小决定了第二限位凸起121在第二侧板12上的设置位置，为了保证第二限位凸起121对第一缓冲板13的限位作用，第二限位凸起121需要设置在第一缓冲板13最大自由变形圆弧与第二侧板12相切位置与第二端部132之间，即0＜b 1≤L/2(或者0＜b 2≤L/2)。而当b 1＞L/2(或者b 2＞L/2)时，由于第一缓冲板13的弯曲变形程度有限，第二限位凸起121很难甚至无法对第一缓冲板13的弯曲变形起到限制作用。
参照图15和图20，温控组件1在纵向Y上的厚度为H，第一限位凸起111在纵向Y上的高度为h 1，且0＜h 1≤H/2；第二限位凸起121在纵向Y 上的高度为h 2，且0＜h 2≤H/2。这是因为，若h 1＞H/2(或h 2＞H/2)，则在电池2产生膨胀变形的过程中，第一缓冲板13产生的弯曲变形程度很小，其不能及时吸收电池2的膨胀变形，从而使得温控组件1无法满足电池2的膨胀力要求。
进一步地，当第一限位凸起111在数量上为一个时，H/8≤h 1≤H/2；当第一限位凸起111在数量上为多个时，所述多个第一限位凸起111的高度相同，且H/20≤h 1≤H/8。
需要说明的是，当只有一个第一限位凸起111时，第一缓冲板13弯曲变形后与该第一限位凸起111之间的接触相当于点接触，此时第一缓冲板13弯曲变形程度较小，若该第一限位凸起111想要对第一缓冲板13起到限位作用，其在纵向Y上的高度h 1不能过小，即H/8≤h 1≤H/2。当第一限位凸起111为多个时，第一缓冲板13弯曲变形后与多个第一限位凸起111之间的接触相当于面接触，此时第一缓冲板13弯曲变形程度较大，则所述多个第一限位凸起111在纵向Y上的高度h 1可适当减小，即H/20≤h 1≤H/8。
类似地，当第二限位凸起121在数量上为一个时，H/8≤h 2≤H/2；当第二限位凸起121在数量上为多个时，所述多个第二限位凸起121的高度相同，且H/20≤h 2≤H/8。其中，第二限位凸起121的数量与其在纵向Y上的高度h 2采用上述设置方式的理由与第一限位凸起111一致，这里不在详细赘述。
在一些实施例中(未示出)，第一限位凸起111和第二限位凸起121可设置在仅设置有第一缓冲板13的实施例中，例如，前述的第一实施例，当然，也可以设置在同时设置第一缓冲板13和第二缓冲板14实施例中，例如，前述的第三实施例，其中，第二缓冲板14可形成为板状结构或者弧形状结构，第二缓冲板14用于与第一缓冲板13一起吸收电池2的膨胀变形，由此保证温控组件1满足电池2的膨胀力要求，提高了电池2的使用寿命。
参照图13和图19，第二缓冲板14可沿上下方向Z与第一缓冲板13间隔设置，此时第二缓冲板14、第一缓冲板13、第一侧板11以及第二侧板12围成梯形的通道F。
第二缓冲板14可直接连接于第一缓冲板13，此时第二缓冲板14、第一缓冲板13与第一侧板11围成三角形的通道F，第二缓冲板14、第一缓 冲板13与第二侧板12也围成三角形的通道F。
第一侧板11还可设置有：第三限位凸起112，沿纵向Y朝向第二侧板12延伸，且第三限位凸起112处于第二缓冲板14在第一侧板11上的投影区域内。第二侧板12还可设置有：第四限位凸起122，沿纵向Y朝向第一侧板11延伸，且第四限位凸起122处于第二缓冲板14在第二侧板12上的投影区域内。
在第二缓冲板14的弯曲变形过程中，由于第三限位凸起112和第四限位凸起122的设置，第二缓冲板14最终会抵靠到第三限位凸起112和第四限位凸起122上(如图16和图21所示)，从而使得第二缓冲板14的弯曲变形受到限制，进而使得对应的通道F依然具有满足热管理要求的通风空间，由此提高了温控组件1对电池2的热管理性能，从而极大地提高了电池2的使用寿命。
第二缓冲板14具有第三端部141和第四端部142，且所述第三端部141连接于第一侧板11、所述第四端部142连接于第二侧板12。其中，第三限位凸起112和第三端部141之间的位置关系与第一限位凸起111和第一端部131之间的位置关系一致、第四限位凸起122和第四端部142之间的位置关系与第二限位凸起121和第二端部132之间的位置关系一致，这里不在详细赘述。
第三限位凸起112与第四限位凸起122相对设置。具体地，第三限位凸起112与第四限位凸起122在纵向Y上齐平设置；或者，第三限位凸起112与第四限位凸起122在上下方向Z上错位设置。
为了保证第一侧板11和第二侧板12的抗挤压强度，第三限位凸起112和第四限位凸起122的数量可根据强度要求进行选择性设置。
在前述第三实施例中第一侧板11、第二侧板12、第一缓冲板13、第二缓冲板14、第一连接板15以及第二连接板16可采用挤铝工艺一体成型。第一缓冲板13和第二缓冲板14在数量上可均为多个、第二缓冲板14与第一缓冲板13依次交错排列，且在上下方向Z上每相邻的第二缓冲板14和第一缓冲板13与第一侧板11的对应部分、第二侧板12的对应部分均围成一个通道F。换句话说，第一侧板11、第二侧板12、第一连接板15以及第二连接板16一起形成的空腔被第一缓冲板13和第二缓冲板14划分为多个通道F。
参照图27、图30和图31，通道F可具有：宽面F1、窄面F2和限位凸起F3；窄面F2沿纵向Y与宽面F1相对设置，限位凸起F3沿纵向Y突出于宽面F1并与窄面F2间隔设置，且限位凸起F3的至少部分处于窄面F2在宽面F1上的投影区域内。其中，通道F内的限位凸起F3在数量上可为一个或多个。
在电池包的工作过程中，电池2会产生膨胀力，相邻两个电池2(即第一电池2A和第二电池2B)的膨胀力分别挤压第一侧板11和第二侧板12、而第一侧板11和第二侧板12会将膨胀力传递给第一缓冲板13和第二缓冲板14。由于第一缓冲板13和第二缓冲板14的倾斜设置，第一缓冲板13和第二缓冲板14在膨胀力的作用下容易产生弯曲变形以及时吸收电池2的膨胀力，由此保证温控组件1满足电池2的膨胀力要求。同时，在第一缓冲板13和第二缓冲板14的弯曲变形过程中，由于限位凸起F3最终会抵靠到通道F的窄面F2上，从而使得通道F依然具有足够的通风空间，由此提高了温控组件1对电池2的热管理性能，从而极大地提高了电池2的使用寿命。
在一些可能的实施例中，对于在上下方向Z上相邻的第一缓冲板13和第二缓冲板14来说，第一缓冲板13位于第二缓冲板14下方，通道F的宽面F1为第一侧板11面向第二侧板12的表面、窄面F2为第二侧板12面向第一侧板11的表面，即通道F内的限位凸起F3设置于第一侧板11。
参照图27、图30和图31，第一缓冲板13可具有：第一端部131，连接于第一侧板11；以及第二端部132，连接于第二侧板12。第二缓冲板14可具有：第三端部141，连接于第一侧板11；以及第四端部142，连接于第二侧板12。通道F的宽面F1为第一侧板11处于第一端部131与第三端部141之间的表面部分、窄面F2为第二侧板12处于第二端部132与第四端部142之间的表面部分。
第一侧板11在纵向Y上的壁厚为c 1，限位凸起F3面向窄面F2的表面在上下方向Z上尺寸为b，如图30所示。在第一缓冲板13和第二缓冲板14的弯曲变形过程中，由于限位凸起F3会通过第二侧板12上的窄面F2挤压对应电池2的大面，为了防止电池2因限位凸起F3施加的过大挤压力而发生析锂现象，则c 1＜b。为了有效地减小限位凸起F3对对应电池2的挤压力，以减轻限位凸起F3对对应电池2大面的应力集中，优选地， 2.5c 1≤b≤l，其中，窄面F2在上下方向Z上的尺寸为l，如图30所示。
在另一些实施例中，对于在上下方向Z上相邻的第一缓冲板13和第二缓冲板14来说，第一缓冲板13位于第二缓冲板14上方，通道F的宽面F1为第二侧板12面向第一侧板11的表面、窄面F2为第一侧板11面向第二侧板12的表面，即通道F内的限位凸起F3设置于第二侧板12。
参照图27、图30和图31，第一缓冲板13可具有：第一端部131，连接于第一侧板11；以及第二端部132，连接于第二侧板12。第二缓冲板14可具有：第三端部141，连接于第一侧板11；以及第四端部142，连接于第二侧板12。通道F的宽面F1为第二侧板12处于第二端部132与第四端部142之间的表面部分、窄面F2为第一侧板11处于第一端部131与第三端部141之间的表面部分。
在上述实施例中，第二侧板12在纵向Y上的壁厚为c 2，限位凸起F3面向窄面F2的表面在上下方向Z上尺寸为b，如图30所示。在第一缓冲板13和第二缓冲板14的弯曲变形过程中，由于限位凸起F3会通过第一侧板11上的窄面F2挤压对应电池2的大面，为了防止电池2因限位凸起F3施加的过大挤压力而发生析锂现象，则c 2＜b。为了有效地减小限位凸起F3对对应电池2的挤压力，以减轻限位凸起F3对对应电池2大面的应力集中，优选地，2.5c 2≤b≤l，其中，窄面F2在上下方向Z上的尺寸为l，如图30所示。
参照图30，温控组件1在纵向Y上的厚度为H，限位凸起F3在纵向Y上的高度为a。在第一缓冲板13和第二缓冲板14的弯曲变形过程中，由于限位凸起F3的高度a决定了变形后的通道F的通风空间大小，为了保证温控组件1对电池2的热管理性能，则1/5H≤a＜H。优选地，1/3H≤a≤1/2H。
参照图30、图31，限位凸起F3可具有：主体部F31，从宽面F1朝向窄面F2延伸；以及突出部F32，设置于主体部F31靠近窄面F2的一端并沿周向突出于主体部F31(即突出部F32的在周向上尺寸大于主体部F31在周向上的尺寸)，且突出部F32的至少部分处于窄面F2在宽面F1上的投影区域内。
在第一缓冲板13和第二缓冲板14的弯曲变形过程中，限位凸起F3的突出部F32会通过窄面F2挤压对应电池2的大面，由于突出部F32的 在周向上尺寸大于主体部F31在周向上的尺寸，其在尽可能不减小变形后的通道F的通风空间，还保证了突出部F32与窄面F2之间的接触面积，以减小限位凸起F3对对应电池2的挤压力。
参照图1、图2、图9和图24，下箱体3用于支撑所述多个电池2。所述多个电池2在横向X上可排列成至少两排电池排S，风道组件4设置于两排电池排S之间并固定于下箱体3。温控组件1具有多个通道F、风道组件4与对应的电池排S形成有风道，且所述风道连通于对应的温控组件1的多个通道F和风机5。具体地，参照图23，风道组件4可包括风量调节板41、第一支撑板42、第二支撑板43、安装板44以及密封条45。
风量调节板41设置于所述风道内，第一支撑板42与第二支撑板43在纵向Y上间隔设置且第一支撑板42靠近风机5。其中，风量调节板41的高度沿第一支撑板42朝向第二支撑板43的方向依次减小，以使所述风道沿纵向Y从靠近风机5一侧向远离风机5一侧扩张。
安装板44沿纵向Y延伸并连接于第一支撑板42和第二支撑板43，且风量调节板41固定安装于安装板44。密封条45设置于第一支撑板42、第二支撑板43以及安装板44上。当风道组件4与多个电池2完成装配后，密封条45粘接于对应的电池排S以与该电池排S密封连接。
电池包在使用过程中，在风机5的作用下，外部空气能够进入温控组件1的多个通道F中，以实现对电池2的散热。同时，基于风量调节板41的设置，外部空气进入不同温控组件1的量不同，由此实现对所有电池2的均匀散热。
参照图1、图2、图9和图24，端板8在纵向Y上设置于各电池排S两端。扎带6沿周向箍紧对应一个电池排S中的所有电池2、对应的温控组件1以及对应的两个端板8。安装面板9在纵向Y上位于对应的端板8外侧、固定连接于下箱体3以及对应的端板8、并固定安装风机5。
参照图1、图2，线束隔离板10设置于所述多个电池2上方并直接固定于端板8，由此有助于提高电池包的成组效率以及一体化程度。上箱盖7设置于线束隔离板10的上方并通过紧固件(如铆钉)与线束隔离板10固定连接。这里，由于上箱盖7的周侧未设置卡扣等复杂结构，因而其可采用吸塑工艺直接加工而成，从而降低了加工成本。
