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.
