Description

Technical Field

[0001] This invention relates to the field of new energy power lithium battery transportation technology, and in particular to a safe vehicle for transporting power lithium batteries and its working method. Background Technology

[0002] The new energy vehicle industry is booming, and the transportation volume of power lithium batteries, as a core component of new energy vehicles, is also experiencing explosive growth. Lithium-ion batteries pose certain safety risks during transportation. Currently, mainstream power batteries still use liquid electrolyte technology. Liquid electrolyte lithium batteries are characterized by a relatively low thermal runaway trigger temperature. Although battery manufacturers and vehicle manufacturers have adopted various active and passive safety strategies, the batteries still have inherent safety risks. Especially during transportation, the environmental temperature, humidity, and vibration conditions are complex and harsh. Power lithium batteries exposed to these conditions for extended periods increase safety risks. Furthermore, during transportation, power lithium batteries are often offline, and when the internal cell temperature becomes abnormal, they cannot be controlled within a suitable range using their own liquid cooling system.

[0003] In logistics and transportation, standard containers are one of the most important and efficient transport vehicles. The transportation of power lithium batteries also largely utilizes containerized containers. However, existing container transport has several problems: 1. The mainstream containers are dry cargo containers (also known as "dry containers"), accounting for over 70%, which lack internal temperature regulation capabilities, while refrigerated containers are more expensive to use; 2. To reduce transportation costs, most containers are not equipped with temperature alarm devices, making it impossible to effectively monitor the internal temperature and promptly activate emergency plans; 3. Containers are all enclosed structures, and the tail doors are locked during transport, which to some extent hinders the response to sudden battery thermal runaway accidents. In summary, it can be seen that lithium batteries themselves have a potential risk of thermal runaway, and existing container transport technology is insufficient to meet the transportation safety requirements of new energy power lithium batteries.

[0009] Therefore, there is an urgent need for a safe vehicle for transporting power lithium batteries to achieve safe and efficient transportation of power lithium batteries. Summary of the Invention

[0010] This invention addresses the problems in the prior art by proposing a safe transport vehicle for power lithium batteries and its operating method. It is primarily used for the safe and efficient transport of power lithium batteries. Its main features include power lithium battery transport status monitoring, thermal runaway early warning, and emergency response functions. It can promptly remove power lithium batteries with potential fire sources from the vehicle, minimizing losses and ensuring safety during transport. Furthermore, with safety guaranteed, the capacity of power lithium batteries can be significantly increased by utilizing a universal power battery rack.

[0011] To achieve the above objectives, the present invention provides the following technical solution: The first objective of this invention is to provide a safe transport vehicle for power lithium batteries, the vehicle comprising a container body, a load-bearing and securing system, a condition monitoring and analysis system, and an emergency response system.

[0012] Furthermore, the container body has a built-in load-bearing and fixing system, which is used to load and fix a certain number of power lithium batteries of one or more specifications.

[0013] Furthermore, the condition monitoring and analysis system is built into the container body, and is used to monitor and analyze the condition of the power lithium battery during transportation.

[0014] Furthermore, the emergency response system is built into the container body to enable emergency response by ejecting the abnormal power lithium battery from the container body.

[0015] Furthermore, the carrying and fixing system includes a power battery rack and a limiting device; the power battery rack is a universal power battery rack; the power battery rack is installed inside the container and is used to load one or more different types and / or specifications of power lithium batteries; the limiting device is installed inside the power battery rack to ensure that the power lithium battery is relatively fixed in position within the carrier and to prevent the power lithium battery from shifting or colliding during transportation.

[0016] Furthermore, one or more power battery racks are provided, and each power battery rack is equipped with one or more sets of limiting devices to realize the loading and fixing of a certain number of power lithium batteries of one or more types and / or specifications.

[0017] Furthermore, the condition monitoring and analysis system includes a gas sensor and a temperature sensor; the gas sensor is installed on the top of the container body; and the temperature sensor is installed on the surface of each transported power lithium battery.

[0018] Furthermore, the condition monitoring and analysis system also includes a microcontroller subsystem; the gas sensor and temperature sensor are respectively communicatively connected to the microcontroller subsystem.

[0019] Furthermore, the gas sensor features fast response and high sensitivity, and is used to monitor the concentration of specific gas types inside the container in real time, and transmit the detected gas signals to the microcontroller subsystem for further analysis.

[0020] Furthermore, the temperature sensor is used in conjunction with the gas sensor to further confirm abnormal thermal event signals and pinpoint the location of risk sources, monitor the surface temperature of the power lithium battery in real time, and transmit the detected temperature signal to the microcontroller subsystem for further analysis.

[0021] Furthermore, the microcontroller subsystem is used to process and analyze gas and temperature signals, determine whether the power lithium battery is in an abnormal state and whether there is a risk of thermal runaway, and issue corresponding warning signals. At the same time, it can quickly locate the spatial position of the abnormal power lithium battery, and if there is a safety risk, it will send emergency commands to the thrust device of the emergency response system.

[0022] Furthermore, the microcontroller subsystem includes a controller.

[0023] Furthermore, the emergency response system includes a thrust device; the thrust device is located at the power battery rack inside the container. Upon receiving an emergency command from the status monitoring and analysis system, the thrust device activates to push the abnormal power lithium battery out of the container of the vehicle.

[0024] Furthermore, the emergency response system also includes electric doors; electric doors are provided on both sides of the container body, which can effectively improve the loading and unloading efficiency of power lithium batteries during the loading and unloading process. In the event of an emergency during transportation, the electric doors can be opened and, in conjunction with the thrust device, push out the abnormal power lithium batteries.

[0025] Furthermore, the thrust device and the electric door are respectively connected to the microcontroller subsystem of the condition monitoring and analysis system.

[0026] Furthermore, the communication connection can be a wired connection or a wireless connection.

[0027] A second objective of this invention is to provide a method for operating a safe transport vehicle for power lithium batteries, comprising the following steps: Under normal conditions, power lithium batteries are loaded and fixed through a load-bearing and fixing system; When one or more power lithium batteries in the vehicle are in an abnormal state and there is a risk of triggering thermal runaway, the condition monitoring and analysis system detects them through gas sensors and temperature sensors, and further diagnoses the health status of the abnormal power lithium batteries in the container. If there is a safety risk, the spatial location of the abnormal power lithium batteries is locked. The status monitoring and analysis system sends emergency commands to the emergency response system, which opens the electric door and pushes the abnormal power lithium battery out of the container before it catches fire, thus preventing a larger fire and minimizing damage.

[0028] Furthermore, the working method specifically includes the following steps: Under normal conditions, the power lithium battery is loaded and fixed through the power battery rack and limiting device of the load-bearing and fixing system; When one or more lithium-ion batteries in a vehicle inevitably trigger thermal runaway due to uncontrollable factors (such as high temperature, bumpy road conditions, or internal short circuits), a series of side reactions will occur inside the lithium-ion battery (such as the decomposition of the SEI film on the negative electrode surface and the reaction between the electrolyte and metallic lithium), releasing various gaseous substances (such as H2, CO, CH4, etc.). Small molecule gases will overflow from the battery pack and diffuse into the upper space of the container. At this time, gas sensors will detect specific gas types first. When the gas concentration exceeds the safe concentration threshold, the microcontroller subsystem will analyze and determine that there may be a risk of thermal runaway of the lithium-ion batteries inside the container and issue a warning signal. Simultaneously, a series of side reactions inside the lithium-ion battery will release a large amount of heat, causing thermal runaway. As the temperature of the lithium batteries continues to rise, the surface temperature sensor of the power lithium batteries will detect a significant increase in the temperature of one or more power lithium batteries. When the temperature reaches the safety threshold, combined with the gas sensing signal from the gas sensor, the microcontroller subsystem will diagnose that the power lithium batteries inside the container have experienced thermal runaway, confirming a thermal safety event. Based on the sensor sequence (temperature sensors are set up in correspondence with power lithium batteries), the microcontroller subsystem will locate the spatial position of the abnormal power lithium batteries. Furthermore, the microcontroller subsystem will send emergency commands to the electric door and the thrust device, which will work together. When one electric door opens, the corresponding thrust device will open the electric door and push the abnormal power lithium battery out of the container before it catches fire, thus preventing a larger-scale fire and minimizing the damage.

[0029] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: 1) The power lithium battery transport safety carrier of the present invention is mainly used for the safe and efficient transport of power lithium batteries. Its main features are that it has the functions of power lithium battery transport status monitoring, thermal runaway early warning and emergency response. By monitoring the flammable gases such as H2 and CO inside the carrier container and the surface temperature of the power lithium battery, it can realize the early detection and early warning of battery thermal runaway. When abnormal gas or temperature is detected, the built-in micro-control subsystem will analyze and identify whether the power lithium battery inside the container has thermal runaway, so as to remove the power lithium battery with potential fire source from the carrier in time, minimize losses and ensure the safety of the transportation process. Furthermore, on the basis of safety assurance, the carrying capacity of power lithium batteries can be greatly increased by using a universal power battery rack, promoting the high-quality development of the new energy industry.

[0030] 2) The power lithium battery transport safety carrier of the present invention can realize early warning of thermal runaway of power lithium batteries. With the high sensitivity and responsiveness of gas sensing technology, it can detect whether thermal runaway of power lithium batteries in the carrier has occurred in the early stage. If so, it will issue an early warning signal in time to facilitate emergency response. It has an emergency handling function for abnormal batteries. Through temperature sensing technology, it can locate the spatial position of power lithium batteries in abnormal state. Furthermore, with the help of a thrust device, it can push the abnormal batteries out of the box to avoid larger-scale thermal runaway fires.

[0042] Example 1 like Figures 1-2 As shown in the figure, this embodiment provides a safe transport vehicle for power lithium batteries. The structural schematic diagram and the fully loaded schematic diagram are shown in the figure. Figure 1 and Figure 2 As shown.

[0043] The carrier includes a container body 1, a power battery rack 3, a limiting device 4, a thrust device 5, a temperature sensor 7, a gas sensor 8, and a microcontroller subsystem 9. Electric doors 2 are installed on both sides of the container body 1, and the power battery rack 3 is located inside the container body 1. The power battery rack 3 is a universal type, used to load power lithium batteries 6, enabling the loading of one or more power lithium batteries 6, thus increasing the carrying capacity. The universal power battery rack can be used to load one or more different models and / or specifications of power lithium batteries 6.

[0044] The limiting device 4 is installed inside the power battery rack 3 to ensure that the power lithium battery 6 is relatively fixed in position inside the carrier, and to prevent the power lithium battery 6 from shifting or colliding during transportation.

[0045] The power lithium battery 6 is loaded and unloaded through the electric doors 2 on both sides of the container body 1, and the power lithium battery 6 is fixed on the universal power battery rack by the limiting device 4 to prevent it from shifting or colliding during transportation.

[0046] Gas sensor 8 and temperature sensor 7 are installed inside container 1, which together monitor the transportation status of power lithium battery 6. The gas sensor 8 is installed on the top inside the container body 1; the temperature sensor 7 is installed on the surface of each transported power lithium battery 6. The gas sensor 8 has the characteristics of fast response speed and high sensitivity. It is used to monitor the concentration of specific gas types inside the container 1 in real time and transmit the detected gas signal to the microcontroller subsystem 9 for further analysis. The temperature sensor 7 is used in conjunction with the gas sensor 8 to further confirm abnormal thermal event signals and locate the risk source, monitor the surface temperature of the power lithium battery 6 in real time, and transmit the detected temperature signal to the microcontroller subsystem 9 for further analysis.

[0047] The thrust device 5 is located at the universal power battery rack and is used to push out the abnormal power lithium battery 6. Specifically, after receiving an emergency command from the status monitoring and analysis system, the thrust device 5 is activated to push the abnormal power lithium battery 6 out of the container body 1 of the vehicle.

[0048] The electric door 2 can effectively improve the loading and unloading efficiency of the power lithium battery 6 during the loading and unloading process. In case of an emergency during transportation, the electric door 2 can be opened and, together with the thrust device 5, push out the abnormal power lithium battery 6.

[0049] The microcontroller subsystem 9 is used to process and analyze gas and temperature signals, determine whether the state of the power lithium battery 6 is abnormal and whether there is a risk of thermal runaway, and issue corresponding warning signals. At the same time, it can quickly locate the spatial position of the abnormal power lithium battery 6. If there is a safety risk, it will send emergency instructions to the thrust device 5 of the emergency response system.

[0050] The microcontroller subsystem 9 has a gas concentration alarm threshold set within it. In this implementation, it can be one or more of H2 and / or CO and / or other specific gases. The safe concentration threshold is set as [X1%, X2%, X3%, etc.]. The safe threshold is set according to the specific gas.

[0053] This embodiment also provides a method for operating a safe transport vehicle for power lithium batteries, specifically including the following steps: Under normal conditions, the power lithium battery 6 is loaded and fixed through the power battery rack 3 and the limiting device 4 of the support and fixing system; When one or more lithium-ion batteries 6 in the vehicle inevitably trigger thermal runaway due to some uncontrollable factors (such as high temperature environment, bumpy road conditions, or internal short circuit), a series of side reactions will occur inside the lithium-ion battery 6 (such as SEI decomposition on the negative electrode surface, reaction between electrolyte and metallic lithium, etc.), releasing various gaseous substances (such as H2, CO, CH4, etc.). Small molecule gases will overflow the battery pack of the lithium-ion battery 6 and diffuse into the upper space of the container body 1. At this time, the gas sensor 8 will first detect the specific gas type. When the gas concentration exceeds the safe concentration threshold [X1%, X2%, X3%, etc.], the microcontroller subsystem will analyze and judge that the lithium-ion battery 6 inside the container body 1 may have a risk of thermal runaway and issue a warning signal; at the same time, a series of side reactions inside the lithium-ion battery 6 will release a large amount of The heat causes the temperature of the power lithium battery 6 to rise continuously. The surface temperature sensor 7 of the power lithium battery 6 will detect a significant increase in the temperature of one or more power lithium batteries 6. When the temperature reaches the safety threshold Y℃, combined with the gas sensing signal from the gas sensor 8, the microcontroller subsystem will diagnose that the power lithium battery 6 inside the container body 1 has experienced thermal runaway, confirming a thermal safety event. Based on the sensor sequence (temperature sensor 7 is set to correspond with power lithium battery 6), the microcontroller subsystem will locate the spatial position of the abnormal power lithium battery 6. Furthermore, the microcontroller subsystem will send an emergency command to the electric door 2 and the thrust device 5. The two will work together, with one electric door 2 opening and the corresponding thrust device 5 pushing the abnormal power lithium battery 6 out of the container body 1 before it ignites, thus preventing a larger-scale fire and minimizing damage. Considering the thermal runaway characteristics and hazards of the power lithium battery 6, once an emergency response is required, it is recommended that the driver or operator move the vehicle to an open area free of people and flammable materials, based on the warning time, before activating the emergency response system to push out the abnormal power lithium battery 6, ensuring the safety of the vehicle itself while avoiding fire and pollution in the surrounding environment.
