[0050] Optionally, when the aircraft suspends the separated high-temperature battery cell, the current order flight is adjusted according to the power difference before and after the separation. When the remaining power of the aircraft after subtracting the power difference does not meet the first power requirement of the current order flight, the second power requirement of returning to the starting point and / or the third power requirement of continuing to travel to the preset relay point is calculated; when the remaining power meets the second power requirement and the third power requirement, the first distance between the starting point and the end point of the order flight is obtained, and the second distance between the relay point and the end point of the order flight is obtained, when the first distance is less than or equal to the second distance, the operation of continuing to travel to the end point from the current position is performed, and when the first distance is greater than the second distance, the operation of continuing to travel to the relay point from the current position is performed.

[0051] Optionally, when the aircraft throws the separated high-temperature battery cell, the order flight is adjusted according to the mass difference before and after the separation and the power difference.

The higher the goods value, the lower the second temperature threshold, and vice versa. The second temperature threshold in both cases is always lower than the runaway temperature limit value of the battery cell. Further, when the aircraft does not carry goods, the second temperature threshold is equal to the runaway temperature limit value of the battery cell.
