具体实施方式
下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
如图1-10所示，本申请实施例提供了一种电池包，包括箱体100、电池模组200、电池监控单元300和安装支架400，电池模组200包括端板210，电池监控单元300安装于安装支架400，电池模组200、电池监控单元300和安装支架400均容纳于箱体100内。
具体地，如图5、7、9所示，安装支架400包括管理系统安装部410和导热部420，管理系统安装部410具有管理系统安装面411，管理系统安装面411设置成安装电池监控单元300。导热部420设置成与电池包的箱体100相贴合，导热部420连接于管理系统安装部410的一端，且设置于管理系统安装面411所在的一侧，即导热部420相对于管理系统安装部410弯折，并向远离管理系统安装部410的方向延伸。在电池包组装时，管理系统安装部410相对设置于电池模组200的端板210的一侧，即管理系统安装部410与端板210相对，且位于端板210的一侧，电池监控单元300安装于管理系统安装面411，导热部420与箱体100贴合。
上述安装支架400，设置有管理系统安装部410和导热部420，在电池包内设置电池监控单元300的固定位置，以将电池监控单元300的热量能够通过管理系统安装部410、导热部420传递至箱体100，进而使箱体100内部的热量尽快散出，以尽可能保证电池监控单元300的工作温度，提高电池监控单元300的可靠性，以及电池包的安全性。
管理系统安装部410可以与端板210贴合设置，以增加安装支架400的支撑能力，使电池监控单元300的安装更可靠。
进一步地，导热部420的外轮廓与箱体100的外轮廓一致，也就是说，导热部420与箱体100仿形设置，在二者安装时，尽可能 使导热部420各处与箱体100均贴合，从而提高安装支架400的导热效率和安装稳定性。
电池包还可以包括导热胶，管理系统安装部410背离管理系统安装面411的一侧和导热部420与箱体100贴合的一面中，至少一者有导热胶，也就是说，可以仅管理系统安装部410背离管理系统安装面411的一侧设置有导热胶，即管理系统安装部410与端板210之间设置有导热胶，以将电池模组200的热量通过安装支架400传递至箱体100；或者仅导热部420与箱体100贴合的一面设置有导热胶，即导热部420与箱体100之间也设置有导热胶，以进一步提高安装支架400与箱体100的导热效率。可以管理系统安装部410背离管理系统安装面411的一侧和导热部与箱体100贴合的一面均设置有导热胶。
安装支架400还包括模组压设部430，模组压设部430连接于管理系统安装部410的远离导热部420的另一端，且与导热部420分别位于管理系统安装部410的两侧，也就是说，模组压设部430向远离管理系统安装部410的方向延伸，其延伸方向与导热部420的延伸方向相反且不共线，模组压设部430采用这种方式，使安装支架400同时与电池模组200固定，能够更好地提高电池包内部的稳定性。
可以理解地，电池包内的电池模组200可以仅设置有一个，也可以设置有多个，在设置有多个时，可以增设有模组压条，以将相邻的电池模组200固定。本申请的一个实施例中，模组压设部430同时压设连接于相邻的端板210上，即相邻的两个端板210可以与同一个模组压设部430连接，显然，这种方式，模组压设部430起到了模组压条的作用，从而使电池包减少模组压条，同时通过安装支架400增加了多个电池模组200与箱体100的连接点，使电池模组200的稳定性更好。
在电池模组200设有三个以上时，模组压设部430设有多个，一个模组压设部430同时压设于相邻的两个电池模组200的端板 210上，如图4所示，电池模组200设有三个，模组压设部430设有两个，各模组压设部430通过螺钉与相邻的两个端板210连接，可以相邻的两个端板210分别通过一个螺钉与模组压设部430固定。
其中，箱体100包括相互扣合的上箱体110和下箱体120，在电池包安装时，先打开上箱体110，将电池模组200、电池监控单元300、安装支架400以及其它电池包内的部件安装于下箱体120，然后再盖合上箱体110，形成电池包。
安装支架400可以通过导热部420与箱体100连接，一种实施例中，导热部420的两侧设置有箱体安装部440，箱体安装部440具有箱体安装面441，箱体安装面441与管理系统安装面411垂直，在安装支架400安装于箱体100时，箱体安装面441垂直于上箱体110与下箱体120的盖合方向，如图3所示，这样，螺钉沿盖合方向设置，以锁紧安装支架400与箱体100。
由于电池监控单元300为易损件，因此，需要经常更换维修。现有技术中，安装支架400在电池包内没有固定位置，在有的位置处，拆卸电池监控单元300以及安装支架400时，没有足够的操作空间，需要将电池模组整个拆卸下来，更换完成后还需要再次重新组装，造成更换电池监控单元300费工费时。而采用上述箱体安装部440，在拆卸维修时，将上箱体110打开后，由于连接安装支架400与箱体100的螺钉以及安装支架400与端板210的螺钉均竖直设置，且其上方没有其它部件，因此，这种方式有足够的操作空间，使电池监控单元300的更换更方便，提高电池监控单元300更换维修的效率。
为了提高箱体100的强度，箱体100可以设置有向内凹陷的台阶130，可以上箱体110和下箱体120均设置有台阶130，箱体安装部440与台阶130贴合连接，采用这种方式，在箱体100的外部形成有凹陷空间，可以用于容纳螺钉，且能够增加箱体100的强度。此时，导热部420相对于箱体安装部440向外凸出，以尽可能 与箱体100贴合。
箱体安装部440与导热部420可以通过弧形面过渡连接，具体地，箱体安装部440和导热部420可以由管理系统安装部410的一个翻边形成，以增加整个安装支架400的强度。
可选地，安装支架400为一体成型结构，以增加安装支架400的强度。管理系统安装部410、导热部420、模组压设部430以及箱体安装部440可以均为板状结构，在安装支架400为一体成型结构时，模组压设部430、箱体安装部440和导热部420均相对于管理系统安装部410弯折成型。
进一步地，安装支架400还包括应力均衡结构450，管理系统安装部410与模组压设部430至少一者设置有应力均衡结构450，以更好地增加安装支架400的强度。
应力均衡结构可以为防撕裂凹槽451，管理系统安装部410设置有防撕裂凹槽451，且防撕裂凹槽451由管理系统安装面411向内凹陷形成，即向端板210凹陷，这种结构能够使管理系统安装面411的大部分区域均与电池监控单元300接触，进而提高电池监控单元300的散热效果。
一种实施例中，尤其在安装支架400一体成型时，由于靠近模组压设部430处弯折造成的内应力比较大，因此，至少管理系统安装部410靠近模组压设部430的区域设置有防撕裂凹槽451，以提高该处的强度，防止在该处产生裂纹。
正如前面所述，在安装支架400为一体成型结构时，管理系统安装部410与模组压设部430的连接处由于弯折易造成断裂，因此，在管理系统安装部410与模组压设部430的连接处设有应力均衡结构450，以增加该处的强度，保证管理系统安装部410与模组压设部430连接的可靠性，该处的应力均衡结构可以为防撕裂孔452，如图5、7、9所示，以更好地释放弯折造成的内应力，防止在该处造成断裂。
需要说明的是，在管理系统安装部410上也可以设置防撕裂孔 452，在管理系统安装部410与模组压设部430的连接处也可以设置防撕裂凹槽451。
除此之外，应力均衡结构450还可以包括弯折边453。管理系统安装部410的至少部分边缘设置有弯折边453，以形成翻边结构，如图5、7、9所示，管理系统安装部410的边缘中位于模组压设部430和箱体安装部440之间的部分设有弯折边453，由于管理系统安装部410的尺寸较大，因此，采用这种翻边结构能够进一步提高安装支架400的强度。
管理系统安装部410上设置有多个通孔，多个通孔中，部分为安装孔，部分为备用孔470，以适应不同规格的电池监控单元300。具体地，各安装孔均可以连接有连接螺栓460，且连接螺栓460与管理系统安装面411位于管理系统安装部410的同侧。这样，由于电池监控单元300的外形结构相似，不同规格的电池监控单元300仅在长度方向上的尺寸有所区别，在生产安装支架400时，先将安装支架400除连接螺栓460的其它结构都加工成型，最后根据不同的电池监控单元300将连接螺栓460连接于安装孔。如图5-10所示，为安装支架400的三个实施例以及对应的实施例与不同的电池监控单元300安装的装配图，三个实施例仅在于连接螺栓460的位置不同，以适应不同的电池监控单元300的安装。显然，这种结构能够提高安装支架400的结构一致性，增加安装支架400的通用性，减少安装支架400的加工模具数量，降低成本，且易于整个电池包的设计。需要说明的是电池监控单元300也可以通过其它方式连接于安装孔，或者直接通过卡接、焊接或者其它连接方式连接于安装支架400。
可选地，安装支架400上还可以设置有散热孔，散热孔也可以为通孔，以便于电池监控单元300的散热。
如图8所示，电池监控单元300与电池包内的其它部件之间需要通过连接线束500连接，即电池包还包括连接线束500，为了防止在电池包运输和使用过程中，连接线束500振动对整个电池包造 成影响，管理系统安装部410还设有线束固定孔480，线束固定孔480可以为通孔或者盲孔，在连接线束500连接好后，通过绑带、线卡子等将连接线束500与线束固定孔480固定。
综上，也就是说，安装支架400上可以设有多个通孔，分别是适配安装不同尺寸电池监控单元300的安装孔和备用孔、固定连接线束500的连接孔，其散热作用的散热孔，除此之外还可以为减重孔。此外，本申请还提供了一种汽车，包括如上任一实施例所述的电池包。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
