A battery bending test system includes a fastening device having an inclined surface configured to hold a battery; a pressing device configured to press the battery to bend; and a load-bearing device configured to bear the fastening device, the load-bearing device having a reference surface for bearing the fastening device. A first angle Ø is formed between the inclined surface and the reference surface. The range of the first angle Ø is 0°<Ø<90°. The battery bending test system and method can precisely control the bending angle and bending morphology of the battery, and reasonably evaluate the safety performance of the battery when subjected to the bending force, thus meeting expectations of the safety test.

Battery bending test system and method

This application relates to a battery test system and a battery test method. The battery test system according to an embodiment comprises: an extrusion apparatus configured to be disposed on a first surface of a battery; and a pressure apparatus, disposed above the extrusion apparatus, where the pressure apparatus is configured to apply a predetermined force to the battery in predetermined duration through the extrusion apparatus. The battery test system and the battery test method provided in this application are able to more reasonably evaluate the safety of the soft package battery and identify the risk caused by the defect of the soft package battery.
