Abstract
The application provides a battery device and a power utilization device. The battery device comprises a box body, at least one battery cell, at least one buffer and at least one first pressure sensor. The box body has a containing cavity, the at least one battery cell is contained in the containing cavity, the buffer is contained in the containing cavity and located between the wall of the box body and the battery cell, and the buffer has at least one buffer cavity in the inside. The first pressure sensor is arranged in the buffer cavity and used for detecting the pressure in the buffer cavity. The battery device provided by the application can detect the pressure change value in the buffer cavity through the first pressure sensor, so as to determine whether the battery device collides and the size of the collision force, so that the staff can process the battery device in time, and the use reliability of the battery device is improved.
