Abstract
A battery test apparatus for testing a swelling force of a battery housing may include equivalent end plates and a retractable part. An actual battery module may be replaced by the battery test apparatus, eliminating the need for a battery module and accompanying charging and discharging devices and reducing the test cost. Two equivalent end plates may be spaced apart along a first direction to replace a battery module actually in contact with the battery housing along the first direction. The retractable part may be arranged between the two equivalent end plates. The retractable part may compress the two equivalent end plates to make the equivalent end plates compress the battery housing.
Claims12
A battery test apparatus for testing a swelling force of a battery housing, wherein the battery test apparatus comprises:
- equivalent end plates, wherein two of the equivalent end plates are spaced apart along a first direction;
- and
- a retractable structure arranged between the two of the equivalent end plates and retractable along the first direction so that the retractable structure is able to compress and move the equivalent end plates along the first direction,
- wherein the retractable structure comprises an actuator and a transmission structure arranged in sequence along the first direction, and the actuator drives the transmission structure to reciprocate along the first direction,
- a drive form of the actuator is gear drive or electromagnetic drive, and
- the transmission structure is a lead screw, and the lead screw is threaded to the actuator.
