The invention discloses an electric connection device and an electric automobile, the electric connection device comprises an automobile end electric connector arranged on the electric automobile and a battery end electric connector arranged on a battery pack, the automobile end electric connector comprises a first high-voltage assembly, and the battery end electric connector comprises a second high-voltage assembly. The first high-voltage assembly is connected with the second high-voltage assembly so as to realize high-voltage electric connection between the electric vehicle and the battery pack; wherein the first high-voltage assembly comprises a first high-voltage pole, the first high-voltage pole is provided with a first end face, the first end face faces one side matched with the battery end electric connector, the first high-voltage pole is provided with at least two mounting grooves, the mounting grooves are formed in the first end face, conductive elastic pieces are embedded in the mounting grooves, and the conductive elastic pieces protrude out of the first end face. The first high-voltage assembly and the second high-voltage assembly are electrically connected through the conductive elastic pieces in the multiple mounting grooves, so that the contact resistance between the first high-voltage assembly and the second high-voltage assembly is smaller, and the high-voltage current bearing capacity is improved.
本发明公开了一种电连接装置及电动汽车,包括设于电动汽车上的车端电连接器与设于电池包上的电池端电连接器,车端电连接器包括第一高压组件,电池端电连接器包括第二高压组件,第一高压组件与第二高压组件相连接以实现电动汽车与电池包的高压电连接;其中,第一高压组件包括第一高压极柱,第一高压极柱具有第一端面,第一端面朝向与电池端电连接器配合的一侧,第一高压极柱具有至少两个安装槽,安装槽开设在第一端面上,安装槽内均嵌设有导电弹性件,导电弹性件突出于第一端面。第一高压组件与第二高压组件通过多个安装槽中的导电弹性件进行电连接,使第一高压组件与第二高压组件之间的接触电阻更小,提高了对高压电流的承载能力。
