Currently, the human society faces climate change, energy crisis and environmental problems, and the problems of greenhouse gas emission, energy consumption and tail gas emission caused by transportation are increasingly severe. In view of the current situation, the international society has reached a consensus, and needs to make efforts to promote the global automobile industry mechanism upgrade and the power system electromotion, so as to finally make the society enter the electric automobile era.

With the popularization of electric vehicles, the demand for lithium batteries is increasing, and the safety of the lithium batteries is becoming more and more important. The curb plate has both needed to guarantee that electric core produces the pulling force in the inflation process as an indispensable part of battery package, needs accomplish insulating protection at the curb plate and the part of electric core contact again, therefore the curb plate adopts the metal material to at the inboard hot pressing one deck insulating PET membrane of curb plate.

In order to ensure the safety of the battery pack, a need arises to perform a withstand voltage test on the side plates. For the withstand voltage test of the side plate, the following method is conventionally adopted: the positive electrode of the withstand voltage tester is clamped on the metal side of the side plate, and the negative electrode probe randomly selects a plurality of points on an insulating PET film (hot-pressing film) of the side plate for testing. However, the conventional method has the following disadvantages: 1. randomly selecting a plurality of points for testing, so that the testing is incomplete, the risk of missing inspection exists, and the quality of the side plate cannot be ensured; 2. in the testing process, different side plates need to be continuously clamped by the positive electrode of the withstand voltage tester, and the operation process is complicated, so that the testing efficiency is low; 3. the side plate is directly clamped by the anode of the withstand voltage tester, so that the damage of the side plate is difficult to avoid.

Therefore, how to provide a withstand voltage test frock of battery package curb plate, realize carrying out omnidirectional withstand voltage test to the curb plate, promote efficiency of software testing, avoid haring the curb plate, become a problem that awaits the solution urgently.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in providing a withstand voltage test frock of battery package curb plate, realizes carrying out omnidirectional withstand voltage test to the curb plate, promotes efficiency of software testing, avoids damaging the curb plate.

The utility model discloses a realize like this: a withstand voltage test tool for battery pack side plates comprises at least two side plates, a metal base and a metal probe plate; the side plate is placed at the upper end of the metal base, and the metal detecting plate is placed at the upper end of the side plate;

an extension part is vertically arranged on the side edge of the metal base; a handle is arranged at the upper end of the metal detecting plate, and the lower surface of the metal detecting plate completely covers the hot pressing film of the side plate.

Further, the upper surface of the metal base is a plane.

Further, the lower surface of the metal probe plate is a plane.

The utility model has the advantages that:

by arranging the metal base and the metal probe plate, when the side plate needs to be subjected to a pressure resistance test, the side plate to be tested is placed on the metal base, the metal probe plate is placed on the side plate to be tested, the extending part of the metal base is clamped by the positive electrode of a pressure resistance tester, and the pressure resistance test can be performed by the contact of the negative electrode probe and the upper side of the metal probe plate; the lower surface of the metal base completely covers the hot-pressing film of the side plate, so that the whole hot-pressing film of the side plate can be subjected to all-around pressure resistance test, and the condition that the quality of the side plate cannot be ensured due to the fact that a plurality of points are randomly selected for testing is avoided; because the extension of metal base is cliied to the positive pole of high-voltage tester, change the examination of awaiting measuring the positive pole of connecting high-voltage tester need not be dismantled again during the curb plate, very big promotion high-voltage tester's efficiency, and the positive pole of high-voltage tester need not clip the curb plate, avoided the damage of curb plate.
