Abstract: A safety detection method for a battery module is provided in this application, which includes: obtaining a plurality of battery temperatures detected by the plurality of temperature sensors at a first moment; determining a standard battery temperature based on the plurality of battery temperatures; obtaining a second battery temperature of a first battery set at a second moment; determining a temperature change rate of first battery set based on a first battery temperature, a second battery temperature, the first moment, and the second moment; and determining that a battery in the first battery set has a liquid leakage risk when a third difference between the first battery temperature detected by the first temperature sensor at the first moment and the standard battery temperature is greater than a first temperature threshold, and the temperature change rate is greater than a temperature change rate threshold.

Abstract: A break separation apparatus and method are provided. The apparatus comprises a vibration stage for holding at least one liquid crystal panel to be separated and vibrating the liquid crystal panel so that glass substrate of the liquid crystal panel breaks along a cutting groove. According to the apparatus and method, the cutting grooves cut on the glass substrate are substantially extended in thickness direction of the glass substrate by vibration method so as to achieve separation, which can be readily controlled and avoid contamination and damage to the liquid crystal panel.
