The invention discloses a safety detection method and device of a battery, a storage medium, an energy storage system and a vehicle, and belongs to the technical field of new energy. The method comprises the following steps: acquiring pressure distribution data of a battery; the pressure distribution data comprises pressure values detected by all pressure detection areas of the pressure sensor; screening out a plurality of effective regions from the plurality of pressure detection regions according to the distance between each pressure detection region and the boundary of the surface region for arranging the pressure sensor on the battery and a preset screening strategy; the pressure change sensitivity of the active regions is greater than the pressure change sensitivity of regions other than the plurality of active regions among the plurality of pressure detection regions. And determining pressure data according to the pressure value of each effective area in the plurality of effective areas. The pressure distribution data is screened by using the pressure change characteristics of the battery distributed at different places of the surface area when the battery is expanded, so that the safety detection is performed on the battery, and the accuracy of the safety detection result is improved.
