The embodiments of the present application relate to a battery bending test system and method. The battery bending test system according to an embodiment includes a fastening device having an arrangement 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 arrangement surface and the reference surface. The range of the first angle Ø is 0° < Ø < 90°. The battery bending test system and method provided by the embodiments of the present application 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.
