BATTERY TESTING METHOD AND DEVICE

A battery testing method and device. The battery testing device comprises: a box (1) having a receiving space (11); a battery testing module (2) provided with a battery testing point (21) for placing a battery to be tested; a temperature control module (3); and a temperature sensor (4) electrically connected to the temperature control module (3). The battery testing module (2), the temperature control module (3), and the temperature sensor (4) are all located in the receiving space (11); the temperature sensor (4) is configured to detect the real-time ambient temperature of the receiving space (11), and sends the real-time ambient temperature to the temperature control module (3); the temperature control module (3) is configured to control the target ambient temperature of the receiving space (11) according to the real-time ambient temperature and a preset test temperature; when the target ambient temperature is equal to the test temperature, the battery testing module (2) is configured to control and/or moni
