The invention relates to the technical field of automobiles, and particularly discloses a grounding device and a grounding method of a new energy automobile power system, at least two wiring pieces are arranged on a common ground base, a first winding at one end of a grounding lead is spirally wound on the wiring pieces, and a second winding of a magnetic induction lead is spirally wound on the wiring pieces; the positive and negative electrode connecting wires of the second winding are electrically connected with the positive and negative electrode contact ends of the induction circuit respectively, when one grounding end of the power system leaks electricity, the second winding and the first winding form a mutual inductance effect, and the induction circuit forms induction current, so that the electric leakage position is determined, and maintenance personnel can check hidden dangers conveniently.

    本发明涉及汽车技术领域,具体公开了一种新能源汽车电力系统的接地装置及接地方法,在共地基座上设置至少两个接线件,将接地导线一端的第一绕组呈螺旋状缠绕在接线件上,将磁感导线的第二绕组呈螺旋状缠绕在接线件上,而且第二绕组的正负极接线分别与感应电路的正负极接触端电连接,当电力系统的其中一个接地端发生漏电现象,第二绕组与第一绕组形成互感效应,感应电路形成感应电流,从而确定漏电位置,便于检修人员排查隐患。
