The invention discloses a battery monomer, a battery module, a battery pack, an energy storage system and an electric vehicle. The single battery comprises one or more stress sensors, and the stress sensors are positioned on the anti-explosion valve and face the outside of a shell of the single battery; or the stress sensor is located on the anti-explosion valve and faces the interior of the shell of the single battery, and the stress sensor is connected with the processor of the battery module; each stress sensor is used for detecting the stress, acting on a corresponding position on the anti-explosion valve, in the battery monomer, and one or more stress sensors are used for transmitting all obtained electric signals to the processor. And the processor determines a target battery cell with a fault according to the received one or more electric signals. By adopting the scheme of the invention, the stress of the battery monomer in operation can be monitored in real time, and the timeliness of stress monitoring is improved.
