[0049] Reference Figure 1 , Figure 1 This is an optional flow chart of a method for handling thermal runaway of a battery pack provided in an embodiment of the present application. The method may include but is not limited to steps S101 to S103:

[0050] Step S101, receiving a battery pack thermal runaway signal and acquiring battery pack thermal runaway status information;

[0051] Step S102, determining a thermal runaway processing scheme according to the thermal runaway state information of the battery pack;

[0052] Step S103, generating corresponding control instructions according to the thermal runaway processing scheme, and using the control instructions to control the thermal runaway processing system to perform thermal runaway processing.

[0053] In some embodiments, the battery pack status is dynamically monitored to determine whether thermal runaway has occurred in the battery pack. When it is determined that thermal runaway has occurred in the battery pack, a battery pack thermal runaway signal is generated. After receiving the battery pack thermal runaway signal, the battery pack is thermal runaway processed to prevent the battery pack from continuing to send thermal runaway signals, resulting in fire or fire spread, etc., causing losses.

[0054] In some embodiments, step S101 may include but is not limited to steps S201 to S203:

[0055] Step S201, monitoring the current temperature of the environment in which the battery pack is located, the current smoke concentration of the environment in which the battery pack is located, and the current thermal imaging detection temperature of the battery pack;

[0056] Step S202, determining whether to generate a battery pack thermal runaway signal according to the current temperature of the battery pack environment, the current smoke concentration, and the current thermal imaging detection temperature;

[0057] Step S203, when it is determined that a battery pack thermal runaway signal is generated, the current thermal imaging detection temperature and the current smoke concentration are obtained to determine the battery pack thermal runaway state information.

[0058] In some embodiments, optionally, the current temperature of the environment in which the battery pack is located is collected by a temperature sensor provided on the battery pack, thermal imaging detection is performed on the battery pack by a thermal imaging camera device to collect the current thermal imaging detection temperature corresponding to the battery pack, and the corresponding current smoke concentration is collected by a smoke sensor provided in the environment in which the battery pack is located.

[0059] In some embodiments, a comprehensive judgment is made as to whether thermal runaway has occurred in the battery pack based on the current temperature of the battery pack's environment, the current smoke concentration, and the current thermal imaging detection temperature. When thermal runaway has occurred in the battery pack, a battery pack thermal runaway signal is generated. Since the temperature detection accuracy of the thermal imaging camera device is higher than the temperature detection accuracy of the temperature sensor, the battery pack is processed for thermal runaway based on the current thermal imaging detection temperature. Therefore, the current thermal imaging detection temperature and the current smoke concentration are obtained as the thermal runaway status information of the battery pack.

[0063] Step S303, when the current thermal imaging detection temperature exceeds a preset battery pack thermal runaway temperature threshold, a third thermal runaway signal is generated;

[0064] Step S304 : when it is determined that at least two of the first thermal runaway signal, the second thermal runaway signal and the third thermal runaway signal are generated, a battery pack thermal runaway signal is generated.

[0065] In some embodiments, when it is determined that at least two of the first thermal runaway signal, the second thermal runaway signal, and the third thermal runaway signal are generated, a battery pack thermal runaway signal is generated, and a comprehensive judgment is made on the thermal runaway of the battery pack to avoid false alarms of thermal runaway signals due to abnormalities in a single thermal runaway detection device (including temperature sensors, thermal imaging cameras, and smoke sensors, etc.), thereby improving the monitoring accuracy of battery pack thermal runaway.

[0069] Step S403, determining a target water immersion cooling level according to the current thermal imaging detection temperature, and determining a target water immersion isolation solution that matches the target water immersion cooling level from the water immersion isolation treatment solutions.

[0070] In some embodiments, optionally, multiple fire extinguishing levels are set, each fire extinguishing level corresponds to a smoke concentration range, and a target fire extinguishing level matching the current smoke concentration is determined from the multiple fire extinguishing levels, wherein the current smoke concentration is in the smoke concentration range corresponding to the target fire extinguishing level.
