The storage control unit is mainly used for receiving and storing the data collected by the sensor unit, carrying out real-time analysis according to the data and confirming whether the test conditions of thermal runaway and thermal runaway diffusion are achieved, so that feedback control signals are provided for the charge and discharge instrument unit and the heating unit, and the control of thermal runaway triggering is realized. For example, when each parameter in the sensor unit received by the storage control unit is greater than a preset value in the storage control unit, the storage control unit needs to send a signal to the trigger unit, if each parameter in the sensor unit received by the storage control unit is related to the overcharge-triggered thermal runaway, the charge and discharge instrument stops working, and if each parameter in the sensor unit received by the storage control unit is related to the heating-triggered thermal runaway, the heating system stops working.
