The present application discloses a method, apparatus, device, and system for monitoring battery pack safety. The method includes: obtaining, based on obtained stress data of a battery pack in an electric vehicle, stress energy information of the battery pack; determining a target-level alarm condition based on the stress energy information and sending corresponding alarm information, where the target-level alarm condition is a level of alarm condition in preset N levels of alarm conditions that the stress energy information satisfies, an ilevel of alarm condition indicates that there are moccurrences of impact energy represented by the stress energy information that is within an ienergy threshold range, and a lower limit of the ienergy threshold range of the ilevel of alarm condition is greater than an upper limit of an (i−1)energy threshold range of an (i−1)level of alarm condition, and m<m.
