如图1、图2所示，本公开实施例的动力电池包，由外部的壳体以及设置于壳体内部的电芯集成模块组成。
壳体包括上半壳体1、下半壳体7、前面板10以及前端盖13，上半壳体1与下半壳体7连接，前面板10分别与上半壳体1以及下半壳体7连接，前端盖13覆盖在前面板10上。
电芯集成模块20设置在壳体内部，上半壳体1与下半壳体7连接后中部形成的空腔为壳体内部，电芯集成模块20由多个电芯3集成，通过连接片4连接在每个电芯3之间的正负极，电芯集成模块20的正负极通过连接片4与外部正负极接插件15连接，前面板10设置在电芯集成模块20的前端，外部正负极接插件15设置在前面板10上。
动力电池包的上半壳体1包括壳体的顶面、壳体的左右上半个侧面以及壳体的后面，下半壳体7包括壳体的底面、壳体的左右下半个侧面以及壳体的后面，前面板10以及前端盖13构成壳体的前面。上半壳体1、下半壳体7、前面板10以及前端盖13共同构成动力电池包的外壳体。动力电池包内部为电芯集成模块，电芯集成模块直接由电芯3集结而成，通过胶水或者其他紧固件将电芯集结在一起，电芯3之间通过连接片4连接正负极，电芯集成模块20的正负极通过连接片4连接到外部正负极接插件15上，外部正负极接插件15设置在电池包的前面板10上。电池包内部直接由电芯集结而成，电池包的结构比较紧凑， 而且电池包可以由电芯3本身的壳体作为支撑，不需要再另外增加相关支撑附件，从而省略了相关技术中的电池包内部支撑件以及电池模块组件等附件，减少了电池包内部的附件布置数量，提高了电池包的电芯集成率，进而提升了电池包的能量密度。
其中，前面板10上设置有信息采集器11以及外部低压接插件14，电芯集成模块20的侧面设置有柔性电路板5，柔性电路板5上设置有温度传感器以及电压传感器，柔性电路板5连接信息采集器11，信息采集器11连接外部低压接插件14。
电池包内部电芯集成模块20的侧面设置有柔性电路板5，柔性电路板5上设置有温度传感器以及电压传感器，用于采集温度以及电压参数信息，柔性电路板5连接信息采集器11，电池包前面板10上设置有外部低压接插件14，信息采集器11连接外部低压接插件14，从而将采集到的温度、电压信息传送到电池包外部。
电池包前面板10上的信息采集器11内部集成有烟雾检测模块，烟雾检测模块可以集成于信息采集器11内部的电路板，当烟雾检测模块检测到电池包内部出现烟雾时自动触发烟雾报警，以控制安装在电池包内部的灭火装置9触发，从而防止发生灾害。
电池包前面板10上设置有保险丝12，保险丝12与电芯集成模块20连接。当电池包充放电电流异常时，保险丝12自动熔断以保护电池包。
本公开实施例的动力电池包内部还设置有冷却管道8，电池包壳体上设置有外部冷却接口，冷却管道8与外部冷却接口连接，外部冷却系统可以通过外部冷却接口对电池包内部进行冷却。冷却管道8可以设置在电芯集成模块与壳体之间，也可以设置在电芯3之间，从而对动力电池包进行冷却。其中，动力电池包的冷却使用外部冷却系统，动力电池包的冷却可以接入车辆冷却系统，动力电池包的冷却也可以是车辆空调系统，或者是单独设置的动力电池包冷却系统。通过外置的冷却系统对动力电池包进行冷却，冷却效果较好，在一定程度上能够达到降低能耗的目的，同时对动力电池包内部的电芯布置影响不大。
