1. A cell evaluation device for evaluating the safety of a cell based on a state of a test cell when pressure is used to forcibly generate an internal short circuit within the test cell, the cell evaluation device comprising:

  • a short circuit detector for detecting the occurrence of an internal short circuit within the test cell, the test cell including an electrolyte solution;

    a pressure controller for controlling the pressure applied once the short circuit detector has detected the internal short circuit; and

    a cell information detector for detecting the state of the test cell,wherein said short circuit detector is configured, upon detection of the internal short circuit within the test cell, to output a short circuit detection signal to the pressure controller and to the cell information detector.
