The invention provides an electromagnetic interference filtering device and an electric vehicle, and relates to the technical field of vehicle control. The electromagnetic interference filtering device comprises a shielding shell, a differential mode electromagnetic interference filtering component and a common-mode electromagnetic interference filtering component, wherein two opposite end faces of the shielding shell are respectively provided with an opening for an alternating-current wire harness to pass through; the differential mode electromagnetic interference filtering component is arranged in the shielding shell and is close to an electromagnetic interference source; the common-mode electromagnetic interference filtering component is arranged in the shielding shell and is far away from the electromagnetic interference source; and the differential mode electromagnetic interference filtering component and the common mode electromagnetic interference filtering component are respectively arranged on the alternating-current wire harness in a penetrating manner. According to the scheme, electromagnetic interference is effectively restrained, and normal work of the vehicle and components around the vehicle is ensured.

    本发明提供一种电磁干扰滤除装置及电动汽车,涉及整车控制技术领域,所述电磁干扰滤除装置包括:屏蔽壳体,所述屏蔽壳体相对的两端面上分别开设有供交流线束穿过的开口;差模电磁干扰滤除部件,设置于所述屏蔽壳体内且靠近电磁干扰源;共模电磁干扰滤除部件,设置于所述屏蔽壳体内且远离所述电磁干扰源;其中,所述差模电磁干扰滤除部件和所述共模电磁干扰滤除部件分别穿设于所述交流线束。本发明的方案实现了对电磁干扰的有效抑制,确保车辆及车辆周围的部件的正常工作。
