The embodiment provides a fire detection method and a fire detection device, which are applied to a fire detector 10 and can improve the judgment accuracy of the thermal runaway phenomenon.
The fire detector 10 is mainly connected with the energy storage battery pack and used for detecting whether a thermal runaway phenomenon occurs in the energy storage battery pack or not and whether a fire occurs or not, and under the condition that the fire occurs, a corresponding alarm signal is sent to remind an operator that the thermal runaway phenomenon occurs in the energy storage battery pack, and fire fighting treatment is needed. However, the method in the prior art has poor accuracy in judging the thermal runaway phenomenon, and is prone to causing misjudgment. The fire detection method and the fire detection device provided by the embodiment can improve the problems and can improve the judgment precision of the thermal runaway phenomenon.

Step S120, determining whether the environmental parameter value is greater than or equal to a preset parameter value.
In this embodiment, whether a fire occurs in the current energy storage battery pack can be determined by comparing the environmental parameter value with the preset parameter value.
It is easy to understand that, under the condition that the environmental parameter value is the environmental temperature value, the preset parameter value is the preset temperature value. If the environmental parameter value is the gas concentration value, the preset parameter value is the preset gas concentration value. And if the environmental parameter value is the smoke concentration value, the preset parameter value is a preset smoke concentration value.
And step S130, if the environmental parameter value is greater than or equal to the preset parameter value, judging that the environmental parameter of the energy storage battery pack meets the condition of fire level.
The preset parameter value comprises a first preset value, the fire level comprises an alarm level, the early warning signal comprises an alarm signal, and the fire detection method further comprises the following steps: judging whether the environmental parameter value is greater than or equal to a first preset value; if the environmental parameter value is greater than or equal to the first preset value, judging that the environmental parameter of the energy storage battery pack meets the condition of an alarm level; and if the thermal runaway phenomenon of the energy storage battery pack occurs, sending an alarm signal.

Under the condition that the environmental parameter value is the environmental temperature value, the first preset value is 50 degrees, and the second preset value is 80 degrees. Under the condition that the environmental parameter value is the smoke concentration value, the first preset value is 5% obs/m, and the second preset value is 15% obs/m.

Wherein the characteristic parameter value comprises a voltage value and/or a temperature value of the battery.
In this embodiment, under the condition that the environmental parameter value of the energy storage battery pack satisfies the fire level, the voltage value and the temperature value of the battery pack are further obtained, and whether the thermal runaway phenomenon occurs in the energy storage battery pack is judged by combining the characteristic parameter value and the environmental parameter value of the battery.
And step S300, judging whether the thermal runaway phenomenon occurs in the energy storage battery pack according to the characteristic parameter value.
In this embodiment, whether the thermal runaway phenomenon occurs in the energy storage battery pack is further determined according to the characteristic parameter value under the condition of the fire level, so that the accuracy of determining the thermal runaway phenomenon can be improved.

Wherein the preset temperature value is 60 degrees.
Step S320, if the temperature value is greater than the preset temperature value, it is determined that the thermal runaway phenomenon occurs in the energy storage battery pack.
In this embodiment, under the condition that the temperature value is greater than the preset temperature value, it indicates that the environmental parameter value is too large at this time, and the temperature value of the battery is also too large, and it can be determined that the thermal runaway phenomenon occurs in the current energy storage battery pack.
In this embodiment, the temperature values of the battery are used to determine whether the thermal runaway phenomenon occurs in the energy storage battery pack in steps S310 and S320.
Referring to fig. 4, in step S330, a voltage difference is calculated according to the voltage value of the previous time and the voltage value of the current time.
In this embodiment, the voltage value is continuously obtained, the voltage difference value can be calculated according to the voltage value at the previous moment and the voltage value at the current moment, and whether the thermal runaway phenomenon occurs is determined according to the voltage difference value, that is, the voltage variation value.
And step S340, judging whether the thermal runaway phenomenon occurs in the energy storage battery pack according to the voltage difference value.
Step S340 may include step S342, step S344, step S346, step S347 and step S348.
Referring to fig. 5, in step S342, it is determined whether the voltage difference is greater than a predetermined difference.
In this embodiment, the preset difference is an upper limit value of the voltage value change of the battery, the voltage value change condition of the battery can be judged by judging the relationship between the voltage difference and the preset difference, and whether the thermal runaway phenomenon occurs can be judged according to the voltage value change condition.
In step S344, if the voltage difference is greater than the preset difference, it is determined that the thermal runaway phenomenon occurs in the energy storage battery pack.
In this embodiment, if the voltage difference is greater than the preset difference, it may be determined that the voltage value of the battery falls, and it is determined that the thermal runaway phenomenon occurs.
Referring to fig. 6, in step S346, a variation difference is obtained by calculating a voltage difference between the current time and the previous time.
In this embodiment, after the variation difference is calculated, whether the thermal runaway phenomenon occurs may be further determined according to the variation difference.
In step S347, it is determined whether the variation difference is greater than or equal to the variation threshold.
The change threshold is an upper limit value of the voltage value change of the battery, the change condition of the voltage value of the battery can be judged by judging the relation between the change difference value and the change threshold, and whether the thermal runaway phenomenon occurs or not can be judged according to the change condition of the voltage value.
In step S348, if the variation difference is greater than or equal to the variation threshold, it is determined that the thermal runaway phenomenon occurs in the energy storage battery pack.
And if the variation difference is larger than or equal to the variation threshold, the voltage value of the battery is considered to have jitter, and the thermal runaway phenomenon is considered to have occurred.
In this embodiment, step S342 and step S344 determine that the thermal runaway phenomenon occurs in the energy storage battery pack by means of voltage drop, and step S346, step S347 and step S348 determine that the thermal runaway phenomenon occurs in the energy storage battery pack by means of voltage jitter.
