In an optional embodiment of the invention, the battery protection system further comprises: a temperature detection assembly; the detecting whether the battery assembly is in a thermal runaway state comprises:

the thermal runaway condition may include a thermal runaway temperature, and when the battery temperature is not less than the thermal runaway temperature, it is determined that the battery assembly 107 satisfies the thermal runaway condition; when the battery temperature is less than the thermal runaway temperature, it is determined that the battery assembly 107 does not satisfy the thermal runaway temperature.
In the sub-step S13, if the battery assembly 107 meets a preset thermal runaway condition, it is determined that the battery assembly 107 is in a thermal runaway state.
When the battery temperature is not less than the thermal runaway temperature, it is determined that the thermal runaway occurs in the battery assembly 107, and then a thermal runaway processing strategy is subsequently executed to cool down the battery assembly 107.
In an alternative embodiment of the invention, one end of the second pipe 104 is connected to a primary medium source 108 providing the refrigerant medium; a first valve 109 is arranged between the primary medium source 108 and the first spray head 105; the controlling the first spray head 105 to spray the cold medium to the battery assembly 107 includes:
opening the first valve 109 to allow refrigerant medium of the primary medium source 108 to pass in the second conduit 104; the first spray head 105 is opened to spray the refrigerant medium toward the battery assembly 107.
A first valve 109 is arranged in the second conduit 104, in particular, the first valve 109 is arranged in the second conduit 104 between the first spray head 105 and the main medium source 108.
When the first valve 109 is opened, the cold medium stored in the main medium source 108 can be transferred to the first spray head 105 and the second spray head 106 along the second pipeline 104; when the first valve 109 is closed, the cold medium stored in the main medium source 108 cannot be transferred to the first showerhead 105 and the second showerhead 106.
For the positional relationship between the first nozzle 105 and the second nozzle 106, the cold medium as shown in fig. 1 can be transmitted to the second nozzle 106 through the first valve 109 and the first nozzle 105; the cold medium may also be delivered to the first nozzle 105 through the first valve 109 and the second nozzle 106.
In one example, the primary media source 108 is an air conditioner that can have a refrigerant media stored therein, and the air conditioner can provide some or all of its stored refrigerant media to the second conduit 104.
When it is determined that the battery assembly 107 meets the preset thermal runaway condition, the first valve 109 is opened to transfer the refrigerant medium in the primary medium source 108 along the second pipe 104, and the first spray head 105 is opened to spray the refrigerant medium toward and to the battery assembly 107 by the first spray head 105 disposed opposite to the battery assembly 107 when the refrigerant medium is transferred to the first spray head 105, so as to cool the battery assembly 107.
In an alternative embodiment of the present invention, the battery protection system further comprises a pressure sensing assembly 110 disposed between the first valve 109 and the second nozzle 106; the method further comprises the following steps:
acquiring pressure information obtained by the pressure detection component 110 by detecting the cold medium;
judging whether the pressure information is larger than a preset first pressure threshold value or not;
if the pressure information is greater than the preset first pressure threshold, the open state of the first valve 109 is adjusted to reduce the output of the refrigerant medium of the main medium source 108.
The pressure detection assembly 110 may include one or more pressure detection sensors.
The pressure sensing assembly 110 is capable of sensing pressure information at a location in the second conduit 104 from which it is determined whether a sufficient amount of refrigerant medium is present in the second conduit 104.
When the pressure information detected by the pressure detecting component 110 is greater than the preset first pressure threshold, and it is determined that a certain amount of refrigerant is stored in the second pipeline 104, the opening state of the first valve 109 may be adjusted, for example: the opening state of the first valve 109 is controlled by controlling the conduction ratio of the conduction area of the two ends of the second pipe 104 where the first valve 109 is located to the cross-sectional area thereof. Specifically, when the on-state ratio is 100%, the first valve 109 is fully opened; when the on-state ratio is 0, the first valve 109 is completely closed, and the refrigerant cannot be transferred from the main medium source 108 to the first showerhead 105.
When the pressure information is greater than the first pressure threshold, the on-state ratio of the first valve 109 may be decreased to decrease the amount of the refrigerant medium flowing through the first valve 109 from the main medium source 108 per unit time, so as to decrease the output of the refrigerant medium from the main medium source 108.
In an optional embodiment of the present invention, the controlling the fluid driving assembly 102 to drive the cooling fluid to circulate in the first pipe 101 includes:
in the substep S21, if the pressure information is less than a preset second pressure threshold, determining whether the battery temperature is greater than a preset first temperature value;
in sub-step S22, if the battery temperature is greater than the preset first temperature value, the fluid driving assembly 102 is controlled to drive the cooling fluid to circulate in the first pipe 101.
If the pressure information is less than the preset second pressure threshold, it indicates that the coolant medium in the second pipeline 104 has a small mass margin, and the battery assembly 107 cannot be cooled continuously in a manner of spraying the coolant medium onto the battery assembly 107, and then the current battery temperature of the battery assembly 107 is detected, and if the battery temperature is greater than the first temperature value, it indicates that the temperature of the battery assembly 107 is still too high, and it needs to be cooled in an additional manner, and then the fluid driving assembly 102 is started.
The cooling liquid can circulate in the first pipe 101 under the driving of the fluid driving assembly 102, the first pipe 101 can be in contact connection with the battery assembly 107, and the battery assembly 107 can conduct heat energy to the cooling liquid. The circulating coolant can accelerate its own heat dissipation, so that the heat dissipation of the battery assembly 107 can be accelerated.

Two ends of the second valve 112 are respectively connected with the standby medium source 111 and the second pipeline 104, and the standby medium source 111 stores the refrigerant medium.
If the pressure information detected by the pressure detection component 110 is less than the second pressure threshold, it indicates that the amount of the refrigerant medium remaining in the second pipe 104 is insufficient. If the current primary media source 108 has no cold media that can be delivered to the first showerhead 105 and the second showerhead 106, the second valve 112 can be opened to deliver the cold media stored in the backup media source 111 to the first showerhead 105 and the second showerhead 106.
In a particular application, the first valve 109 and the second valve 112 are shut-off valves.

a substep S31 of obtaining a temperature of the cooling liquid detected by the temperature detection component with respect to the cooling liquid;
a substep S32 of judging whether the temperature of the cooling liquid is greater than a preset second temperature value;
in the sub-step S31, if the temperature of the cooling liquid is greater than the second preset temperature value, the second nozzle 106 is opened to spray the coolant medium to the heat conducting assembly 103.
The temperature of the cooling liquid can be determined first, if the temperature of the cooling liquid is greater than the second temperature value, it is indicated that the temperature of the cooling liquid is too high, the temperature of the battery assembly 107 needs to be accelerated to decrease, the second spray head 106 is opened, the cooling medium is sprayed to the heat conducting assembly 103 through the second spray head 106, the heat of the cooling liquid is accelerated to be dissipated through the heat conducting assembly 103, the cooling temperature is reduced, and the temperature of the battery assembly 107 is accelerated to be decreased.
