The invention relates to a battery pack state detection method, device and equipment, a battery pack and a vehicle, and relates to the technical field of new energy automobiles. The method comprises the steps of obtaining a first sensor value of an optical fiber sensor; the multiple optical fiber sensors are arranged on the inner wall of the battery pack shell, and the first sensor value is the output value of the optical fiber sensors at the current moment; acquiring the variable quantity of the first sensor value relative to the second sensor value according to the first sensor value; the second sensor value is an output value of the optical fiber sensor at the reference moment; according to the variable quantity of the first sensor value relative to the second sensor value, the deformation quantity of the battery pack shell is obtained; under the condition that the deformation quantity of the battery pack shell is not smaller than a specified threshold value, prompt information is sent out; the prompt information is used for indicating that the vehicle battery pack shell is in an abnormal state. The driving safety of the vehicle and a driver can be improved, and the service life of the vehicle battery pack is prolonged.
