Battery bending test system and method

A battery bending test method, comprising:

• bearing a fastener by means of a load-bearing structure, the load-bearing structure having a reference surface bearing the fastener;
• holding the battery by means of the fastener having a first inclined surface and a second inclined surface parallel to each other, both of which configured to hold the battery;
• wherein a first angle Ø is formed between the first inclined surface and the reference surface, a range of the first angle Ø being 0°<Ø<90°;
• pressing the battery to bend by means of a press descending straightly at a predetermined speed along a direction perpendicular to the reference surface of the load-bearing structure;
• and
• pressing the battery to a preset condition,
• wherein the fastener comprises a first plate element and a second plate element parallel to the first plate element for holding a part of the battery,
• the first plate element comprises the first inclined surface and a first lateral surface perpendicular to the first inclined surface,
• the second plate element comprises the second inclined surface and a second lateral surface perpendicular to the second inclined surface,
• the first lateral surface and the second lateral surface are on a same plane, and
• the load-bearing structure further comprises an angular adjuster, the angular adjuster is a stationary block between the reference surface and the first inclined surface, and the angular adjuster is configured to adjust the first angle Ø within the range of 0°<Ø<90°,
• wherein the fastener further comprises:
• a third plate element parallel to the first plate element, the second plate element being located between the first plate element and the third plate element;
• and
• a first rod-shaped element penetrating the second plate element and connected to the first plate element and the third plate element;
• wherein the second plate element is movable between the first plate element and the third plate element along the first rod-shaped element.
