The invention provides a dual-motor power assembly and an electric vehicle, a main shell of the dual-motor power assembly comprises two integrated shells and a middle shell, and speed reducer shells of the two integrated shells are fixed to the two side faces of the middle shell respectively. A dual-motor controller of the dual-motor power assembly comprises an electrical assembly and two power modules, a middle shell comprises a containing groove, the containing groove is recessed towards a gap between two speed reducers, the containing groove is used for containing the electrical assembly, the gap between the shells of the two speed reducers is fully utilized, and the power modules are arranged in the containing groove. The connecting plate of each integrated shell is used for enclosing part of the peripheral wall of the motor shell and part of the outer wall of the speed reducer shell of the integrated shell to form an electric control groove, each electric control groove is used for containing one power module, part of the motor shell and part of the speed reducer shell are reused to form the electric control groove, the structure of the integrated shell is more compact and stable, and the service life of the integrated shell is prolonged. And the space between the speed reducer shell and the motor shell is fully utilized, so that the size of the dual-motor power assembly is favorably reduced.

    本申请提供一种双电机动力总成及电动车,双电机动力总成的总壳体包括两个集成壳体和一个中间壳体,两个集成壳体的减速器壳体分别固定于中间壳体的两个侧面。双电机动力总成的双电机控制器包括电气组件和两个功率模组,中间壳体包括容纳槽,容纳槽朝向两个减速器之间的间隙凹陷,容纳槽用于容纳电气组件,充分利用了两个减速器壳体之间的间隙,每个集成壳体的连接板用于围合集成壳体的电机壳体的部分外周壁和减速器壳体的部分外壁构成电控槽,每个电控槽用于容纳一个功率模组,复用了部分电机壳体和减速器壳体形成电控槽,使集成壳体结构更紧凑、稳固,还充分利用了减速器壳体和电机壳体之间的空间,有利于缩小双电机动力总成的体积。
