In the above scheme, when the thermal runaway of the battery pack of the vehicle occurs, the battery pack is controlled to fall off, and the user is reminded to keep away from the vehicle, so that the battery pack is separated from the vehicle under the condition of ensuring the personal safety of the user, and the battery pack is separated from the vehicle by a longer distance through automatic driving so as to ensure that the thermal runaway of the battery pack cannot cause further damage to the vehicle, thereby reducing the influence of the thermal runaway of the battery pack on the property and the personal safety of the user to the maximum extent.
In one embodiment, the controlling the thermal runaway battery to fall off in the event of thermal runaway of the vehicle battery includes:
recording the falling position information of the thermal runaway battery;
sending second warning information to a relevant department, wherein the second warning information comprises: the battery thermal runaway information and the position information of the thermal runaway battery falling off.
For example, after the vehicle controls the thermal runaway battery to fall off, the vehicle records the position information of the thermal runaway battery and sends an alarm to a relevant department, wherein the relevant department may be a fire alarm department and the like, and the fire alarm department informs the fire alarm department of the fire condition of the thermal runaway battery and the position of the thermal runaway battery to quickly locate the dangerous place and carry out rescue.

Claims (10)
1. A control method for thermal runaway of an automobile is characterized by comprising the following steps:
under the condition that a vehicle battery is in thermal runaway, controlling the thermal runaway battery to fall off and sending first warning information to a user, wherein the first warning information comprises: battery thermal runaway information and far vehicle warning information;
starting automatic driving to enable the vehicle to be far away from the thermal runaway battery under the condition that the thermal runaway battery falls off.
2. The method of claim 1, wherein the controlling the thermal runaway battery to drop in the event of a thermal runaway of a vehicle battery comprises:
recording the falling position information of the thermal runaway battery;
sending second warning information to a relevant department, wherein the second warning information comprises: the battery thermal runaway information and the position information of the thermal runaway battery falling.
3. The method of claim 1, wherein initiating autonomous driving to move the vehicle away from the thermal runaway battery in the event the thermal runaway battery falls comprises:
and starting a vehicle engine to provide power for the vehicle under the condition that the thermal runaway battery falls off.
4. The method of claim 1, wherein initiating autonomous driving to move the vehicle away from the thermal runaway battery in the event the thermal runaway battery falls comprises:
acquiring surrounding environment information of the vehicle in real time;
and under the condition that the vehicle surrounding environment information is matched with preset parking environment information, controlling the vehicle to stop automatic driving, and sending the position information of the vehicle to a user.
5. The method of claim 1, further comprising:
and under the condition that the thermal runaway battery falls off, controlling the battery coolant circulating water pump to stop working.
6. The method of claim 1, further comprising:
disconnecting the vehicle from the charging gun if the vehicle is in a charging state and the vehicle battery is thermally out of control.
7. The method of claim 1, further comprising:
and determining the thermal runaway condition of the vehicle battery based on the cell temperature, the temperature rise rate and the pressure of the battery.
8. A control device for thermal runaway of a vehicle, comprising:
the control unit is used for controlling the thermal runaway battery to fall off and sending first warning information to a user under the condition that the vehicle battery is thermally runaway, wherein the first warning information comprises: battery thermal runaway information and far vehicle warning information;
and the starting unit is used for starting automatic driving to enable the vehicle to be far away from the thermal runaway battery under the condition that the thermal runaway battery falls off.
9. A computer-readable storage medium, characterized in that the computer-readable storage medium includes a stored program, wherein the steps of the control method when the vehicle thermal runaway as claimed in any one of claims 1 to 7 are implemented when the program is executed by a processor.
10. An electronic device, comprising at least one processor, and at least one memory coupled to the processor; wherein the processor is used for calling the program instructions in the memory and executing the steps of the control method for the thermal runaway of the automobile according to any one of claim 1 to claim 7.
