Battery testing system

The invention relates to the technical field of battery manufacturing, in particular to a battery testing system. The battery test system comprises a test box body, a telescoping mechanism, a heating member and a needling head. The telescopic mechanism penetrates through the test box body and is sealed with the test box body; the needling head and the heating component are connected with the output end of the telescopic mechanism in a replaceable mode. When the heating component is connected with the output end of the telescopic mechanism, the telescopic mechanism can drive the heating component to heat a sample piece to be tested; when the needling head is connected with the output end of the telescopic mechanism, the telescopic mechanism can drive the needling head to damage the sample piece to be tested. According to the battery test system provided by the invention, the technical problems existing in the thermal runaway test of the whole pack of batteries in the prior art are solved. 本申请涉及电池制造技术领域，尤其是涉及一种
