The tested vehicle is fixed in the automobile test room, and the automobile test room provides the simulation environment required for the simulation test.

[0003] At present, the power batteries of new energy vehicles are mainly lithium iron phosphate batteries and ternary lithium batteries, both of which are lithium batteries. The lithium batteries installed in new energy vehicles may experience thermal runaway during the driving process, charging of the vehicle, and collision of the vehicle. When a lithium battery has thermal runaway, the internal temperature of the battery will rise sharply, and harmful gases will be ejected at the same time, and in severe cases, open flames will be generated. In addition, when a new energy vehicle catches fire, it has the characteristics of large fire, difficult to extinguish, and fast burning, which will seriously endanger the personal safety of personnel in the vehicle test room, and will cause irreparable damage to the equipment in the environmental chamber. For this reason, it is necessary to promptly detach the new energy vehicle from the vehicle fixing pile when the new energy vehicle has thermal runaway, so as to further implement subsequent rescue steps, reduce laboratory losses, and avoid irreparable damage.
