Abstract
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.
Claims14
A battery test system for testing a soft pack battery, comprising:
- an extrusion apparatus configured to be disposed on a first surface of a battery, wherein the battery is a soft pack battery;
- and
- a pressure apparatus disposed above the extrusion apparatus, wherein the pressure apparatus is configured to apply a predetermined force to the battery in a predetermined duration through the extrusion apparatus, wherein a first surface of the extrusion apparatus configured to contact with the first surface of the battery is a substantially flat surface, and a side edge of the first surface of the extrusion apparatus has a chamfer, wherein the predetermined force is 5 KN to 100 KN.
A method for testing a soft pack battery, comprising:
- disposing an extrusion apparatus on a first surface of a battery, wherein the battery is a soft pack battery;
- and
- applying a predetermined force to the extrusion apparatus through a pressure apparatus for a predetermined time to squeeze the battery;
- wherein a first surface of the extrusion apparatus configured to contact with the first surface of the battery is a substantially flat surface, and a side edge of the first surface of the extrusion apparatus has a chamfer, wherein the predetermined force is 5 KN to 100 KN.
