AI Technical Summary

Technical Problem

Existing lithium battery box module mounting surface insulation withstand voltage testing devices cannot accurately test the insulation performance of recessed parts of the module mounting surface, resulting in inaccurate testing.

Method used

A detection device was designed, including a pressing component and a conductive component. The pressing component can cause the conductive component to deform in the thickness direction. It is connected to a conductive device through a wire to ensure that the conductive component is in full contact with the module mounting surface and to detect the insulation performance of the recessed part on the module mounting surface.

Benefits of technology

This improves the accuracy of testing, avoids situations where recessed areas on the module mounting surface are not detected due to poor insulation, and enhances the overall precision of testing.

Abstract

This application discloses a testing device and a testing method. The testing device includes a pressing member, a conductive member disposed on the pressing member, and the pressing member capable of causing the conductive member to deform in a first direction, which is the thickness direction of the conductive member; a wire, which is electrically connected to the conductive member through the pressing member, and / or the wire is electrically connected to the conductive member. The above-mentioned solution provided by this application, because the pressing member can cause the conductive member to deform in the first direction, allows the conductive member to fully contact the recessed portion on the module mounting surface. At this time, the insulation performance of the recessed portion on the module mounting surface can also be detected, avoiding the situation where poor insulation in the recessed portion of the module mounting surface cannot be detected, thereby improving the overall accuracy of the testing.
