Battery testing apparatus and method, production method, device, and medium

A testing apparatus for testing a battery, wherein a battery to be tested is a stacked battery, and the testing apparatus comprises:

• a first ray source;
• a second ray source;
• a third ray source;
• a first detector, opposite to an exit port of the first ray source;
• a second detector, opposite to an exit port of the second ray source;
• a third detector, opposite to an exit port of the third ray source;
• a bearing platform, configured to place the battery to be tested, wherein the bearing platform is movable;
• a movement trajectory of the bearing platform passes between the first ray source and the first detector, and the movement trajectory of the bearing platform passes between the second ray source and the second detector and the movement trajectory of the bearing platform passes between the third ray source and the third detector;
• and
• a testing unit, respectively connected to the first detector and the second detector, wherein the testing unit is configured to perform defect testing on the battery to be tested based on a ray received by the first detector and a ray received by the second detector and the testing unit is further configured to perform defect testing on the battery to be tested based on a ray received by the third detector.
