TEST METHOD, TEST APPARATUS, TEST SYSTEM AND STORAGE MEDIUM

A test method, a test apparatus (126), a test system (116), and a storage medium are provided, so as to solve the technical problem of how the leakage of a battery cell is detected. The test method of this embodiment of this application includes: (S10) obtaining a CAN signal output by a gas sensor (110), where the gas sensor (110) is disposed on a test box (112), and a battery cell is placed in the test box (112); (S20) determining a gas concentration of a predetermined gas in the test box (112) based on the CAN signal; and (S30) sending a concentration exceedance signal when the gas concentration is higher than a concentration threshold.
