Problems solved by technology
[0003] The existing protective measures for lithium-ion battery transportation are mainly divided into two categories: one is to arrange a container with a fire retardant around the lithium-ion battery pack. When a battery explodes due to thermal runaway, the fire extinguishing agent inside the container is released to control the fire. , the disadvantage of this scheme is that each set of lithium-ion batteries needs to be installed, which increases the volume of a single set of lithium-ion batteries, which significantly reduces the transportation efficiency, and this type of protective device is mostly disposable, and the cost is high; the other type is A set of miniature fire extinguishing system is arranged inside the transport vehicle compartment, and the fire detection device is used to link the fire extinguishing system composed of traditional fire extinguishing agents (dry powder, gas) to extinguish the fire
This scheme is relatively perfect in theory, but traditional dry powder and gas fire extinguishing agents have disadvantages such as easy reflammation and low efficiency for extinguishing lithium-ion battery fires, and post-disaster treatment is difficult, which cannot achieve the purpose of early prevention and control

The invention relates to a liquid nitrogen-based lithium ion battery safety transport vehicle, which comprises a transport vehicle body, an equipment bin arranged on the transport vehicle body and a lithium ion battery storage bin arranged behind the equipment bin and used for storing lithium ion batteries, and a liquid nitrogen storage tank and a lithium ion battery management system module are arranged in the equipment bin, a fire detection device and a liquid nitrogen spray head are arranged in the lithium ion battery storage bin, and the liquid nitrogen spray head is communicated with the liquid nitrogen storage tank through a liquid nitrogen pipeline; liquid nitrogen is selected as a cooling protective agent of a lithium ion battery transport vehicle battery pack and a fire extinguishing agent of a fire extinguishing system, the liquid nitrogen spray head is installed in the lithium ion battery storage bin, heat generated by the lithium ion battery pack is absorbed through the efficient cooling performance of the liquid nitrogen, and cooling protection is carried out, adverse effects generated by external factors on the battery pack are reduced, nitrogen generated after the liquid nitrogen serving as an efficient fire extinguishing agent acts can be directly discharged into the atmosphere, environmental protection and no pollution are achieved, and post-disaster treatment is simple.
Description
technical field [0001] The invention belongs to the field of lithium-ion battery transport vehicles, and in particular relates to a lithium-ion battery safety transport vehicle based on liquid nitrogen. Background technique [0002] With its excellent performance and mature technology, lithium-ion batteries are widely used in industries such as electronic equipment, new energy vehicles and energy storage equipment. Therefore, ensuring the safety of lithium-ion battery transportation has become an important prerequisite for the normal development and operation of related industries. [0003] The existing protective measures for lithium-ion battery transportation are mainly divided into two categories: one is to arrange a container with a fire retardant around the lithium-ion battery pack. When a battery explodes due to thermal runaway, the fire extinguishing agent inside the container is released to control the fire. , the disadvantage of this scheme is that each set of lith...
