9. A method of disposing a thermal runaway battery in a power exchange station according to claim 8, wherein after the extension mechanism of the stacker or the thermal runaway battery carried on the stacker touches the touch switch, the door body is flipped or translated away from the emergency exit by the force of an elastic element to open the emergency exit.
10. A method of disposing of a thermal runaway battery within a power plant according to claim 1, wherein the thermal runaway battery is placed in an emergency treatment facility after the thermal runaway battery is transported outside the power plant.
11. The method of disposal of a thermal runaway battery within a power plant of claim 1, wherein after the monitoring system alarms, confirming the temperature of the thermal runaway battery, if the temperature of the thermal runaway battery exceeds the preset threshold, confirming that the alarm is true, suspending power plant; otherwise, the alarm is discharged.
12. A method of disposing of a thermal runaway battery in a power exchange station according to claim 1, wherein the temperature detection device is a battery management system for the battery, the battery management system being capable of interacting with an electrical connection means for charging the battery, the electrical connection means obtaining the temperature of the battery from the battery management system and sending it to the monitoring system.
13. The method of claim 12, wherein the electrical connection device is disposed in a battery compartment in which the battery is stored, and the electrical connection device has a one-to-one correspondence with the battery compartment, and the monitoring system determines the battery compartment in which the thermal runaway battery is located based on the electrical connection device to which the thermal runaway battery is currently electrically connected.
14. A method of disposing a thermal runaway battery in a power exchange station according to claim 1, wherein the temperature detection device is an optical fiber temperature sensor arranged above or below the battery to detect the temperature of the battery and to send to the monitoring system.
15. The method for disposing a thermal runaway battery in a power exchange station of claim 14, wherein the optical fiber temperature sensor is disposed in a battery compartment in which the battery is stored, and the optical fiber temperature sensor has a one-to-one correspondence with the battery compartment, and the monitoring system determines the battery compartment in which the thermal runaway battery is located based on the optical fiber temperature sensor.
