Problems solved by technology

[0002] In the prior art, the fire extinguisher is arranged outside the battery pack, which cannot affect the combustion inside the battery pack, that is, after the battery pack suffers from thermal runaway, it is inevitable that the battery cells will catch fire, while an external fire extinguisher can only delay the fire of the battery pack time, or to extinguish the fire after the battery pack is burned, it is impossible to fundamentally prevent the battery cells from igniting and burning, resulting in poor overall safety of the battery pack, and there is room for improvement

Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0026] Refer below figure 1 A battery pack 100 according to an embodiment of the present invention is described.

[0027] The battery pack 100 according to the embodiment of the present invention may include: a casing, a carbon dioxide generator 1 , an electromagnetic exhaust valve 2 and a battery management system 3 .

[0028] Such as figure 1 As shown, the carbon dioxide generator 1 is arranged in the casing, the volume of the carbon dioxide generator 1 is small, and it is more convenient to be arranged in the battery pack 100, and the carbon dioxide generator 1 is suitable for releasing carbon dioxide gas into the battery pack 100, so as to improve the battery pack capacity. Carbon dioxide concentration within 100.

[0029] The electromagnetic exhaust valve 2 is arranged on the casing so as to open whe...

Abstract

The invention discloses a battery pack, a vehicle and a control method of the battery pack. The battery pack comprises a shell, a carbon dioxide generator, an electromagnetic exhaust valve and a battery management system, wherein the carbon dioxide generator is arranged in the shell; the electromagnetic exhaust valve is arranged on the shell; and the battery management system is arranged in the shell and communicates with the carbon dioxide generator and the electromagnetic exhaust valve separately. According to the battery pack, the combustion and explosion phenomena can be effectively avoided after thermal runaway, so that the overall safety of the battery pack is better.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular, to a battery pack, a vehicle and a control method for the battery pack. Background technique [0002] In the prior art, the fire extinguisher is arranged outside the battery pack, which cannot affect the combustion inside the battery pack, that is, after the battery pack suffers from thermal runaway, it is inevitable that the battery cells will catch fire, while an external fire extinguisher can only delay the fire of the battery pack Time, or fire extinguishing after the battery pack is burned, cannot fundamentally prevent the battery cells from igniting and burning, resulting in poor overall safety of the battery pack, and there is room for improvement. Contents of the invention [0003] In view of this, the present invention aims to provide a battery pack, which can effectively avoid the occurrence of combustion and explosion after thermal runaway, so as to improve th...
