Description

Technical Field

[0001] The invention belongs to the field of lithium battery box emergency separation, in particular to a lithium battery box rapid emergency separation and disposal device. Background Art

[0002] In order to deal with possible dangerous conditions such as thermal runaway, fire, and smoke of lithium batteries, the battery boxes involved should be quickly separated to minimize the harm to the surrounding environment, personnel and other equipment. To this end, it is necessary to use a lithium battery box rapid emergency separation and disposal device. In specific emergency situations, the device is used to quickly separate the lithium battery box from related equipment or systems and properly dispose of it.

[0003] Traditional separation equipment mostly uses a purely mechanical structure for connection and separation, relying only on mechanical locks or bolts to connect the battery box and the surrounding structure. This connection method lacks flexibility and intelligence. In the face of emergencies such as battery thermal runaway, it is impossible to automatically and promptly receive control signals to start the separation process, and manual intervention or reliance on a more complex and slow mechanical trigger mechanism is required, resulting in a long response time. The best time to deal with the situation is often delayed from the discovery of danger to the actual separation, giving the fire or dangerous situation more time to spread.

[0004] To this end, the present invention provides a lithium battery box rapid emergency separation and disposal device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a lithium battery box rapid emergency separation and disposal device described in the present invention, a lithium battery box guard plate is arranged on the top of the lithium battery box compartment bottom plate, a lithium battery box body is arranged inside the lithium battery box guard plate, non-self-locking electrical connectors are arranged at both ends of the top of the lithium battery box guard plate, and electric start separation actuators are arranged at the four corners of the top of the lithium battery box guard plate.

[0007] Preferably, the bottom end of the non-self-locking electrical connector extends to the interior of the lithium battery box guard plate and is electrically connected to the lithium battery box body.

[0008] Preferably, the electric start separation actuator is composed of an electric starter, an electrical interface lead and a fastening functional shell. The fastening functional shell is arranged at the bottom of the electric start separation actuator, the electric starter is arranged at the top of the electric starter, and the electrical interface lead is arranged at the top of the electric starter.

[0009] Preferably, the fastening function housing at the bottom of the electric start separation actuator extends into the lithium battery box guard plate and is threadedly connected to the lithium battery box body.

[0010] Preferably, the opening at the bottom of the lithium battery box guard plate can allow the lithium battery box body to be moved out, and the lithium battery box compartment bottom plate is fixed to the outer periphery of the bottom of the lithium battery box guard plate.

[0011] The beneficial effects of the present invention are as follows:

[0012] The rapid emergency separation and disposal device for a lithium battery box described in the present invention uses an electric starting separation actuator to replace the function of fastening and installing the fixing bolts required for installing the lithium battery box body, and has the function of interlocking with the lithium battery box BMS, vehicle terminal or other fire controllers. After the battery thermal runaway is confirmed to occur, the lithium battery box BMS, vehicle terminal or other fire controller provides a DC pulse starting power supply and the electric starting separation actuator is started, and the fastening installation of the lithium battery box body fails instantly. The lithium battery box body is separated from the lithium battery box cabin bottom plate and the lithium battery box guard plate under the action of gravity, preventing the fire from spreading to the personnel cabin or other equipment in the vehicle, thereby achieving the purpose of minimizing the loss.
