背景技术
随着我国经济建设的快速发展和人民生活水平的不断提高，我国的汽车保有量也在不断增加，从而给我国资源、环境带来巨大的压力。作为重要化工原料——石油，有一半以上是作为机动车的燃料，因此开发节能车辆和使用替代能源是减缓目前能源压力的主要途径。
采用纯电力能源作为新能源汽车成为主流的趋势，然而相关技术中的电动汽车仅设置有一个动力电机，当动力电机的输出端连接有电控机械式自动变速箱(Automated Mechanical Transmission，AMT)后，在AMT换挡过程中，电动汽车的动力中断，进而影响了车辆的使用舒适性，且在爬坡路段，有可能会影响到车辆的行驶安全性。

本公开提供了一种双电机动力总成，使得AMT在换挡过程中整个车辆的动力不会中断、确保了行车的舒适性与安全性，且其结构简单。
一种双电机动力总成，包括：AMT和整车控制器(Vehicle Control Unit，VCU)、差速器、储能装置、第一电机、第二电机、第一电机控制器和第二电机控制器；

所述储能装置为以下任一系统：蓄电池和蓄电池管理系统、超级电容和超级电容管理系统或者蓄电池与超级电容的复合管理系统；
所述第一电机通过三相线与所述第一电机控制器连接，所述第二电机通过三相线与所述第二电机控制器连接，所述第一电机控制器和第二电机控制器分别通过直流线连接到所述储能装置。
本公开的动力总成，AMT在换挡过程中整个车辆的动力不会中断、确保了行车的舒适性与安全性，且结构简单。
附图说明

图中序号所对应的名称如下：
第一电机1、第二电机2。
具体实施方式
一种动力总成，见图1和图2：包括AMT、VCU以及储能装置，第一电机的输出端连接AMT的动力输入端，AMT的动力输出端连接第二电机2的转轴输入端，第二电机2的转轴输出端通过传动轴连接差速器的动力输入端。第一电机1、AMT以及第二电机2为同轴设置，上述结构使得车辆在结构上更紧凑，且动力传输更高效；

实施例二
参见图2，实施例一中的第一电机控制器和第二电机控制器整合成为电机控制模块，电机控制模块带有两个控制输出端，第一控制输出端连接至第一电机1，第二控制输出端连接至第二电机2的电力输入端，电机控制模块电力输入端连接储能装置，VCU的外接电机控制模块的控制输入端。
