[0026] SPECIFICATION DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for explaining the present invention and not for limiting the protection scope of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The form, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the layout form of its components may also be more complex.

[0029] For ease of description, spatial relative relationship terms can be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatial relative relationship terms are intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Therefore, the example term "below" can include both the upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions), and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0030] With the rapid development of the new energy vehicle industry, lithium-ion batteries are widely used due to their high energy density, zero emissions, low self-discharge, and low memory effect. However, higher energy density and faster charging speed also bring new challenges - battery safety issues. The safe application of batteries is the primary focus and research point in the current research and development of new energy batteries, and it plays a crucial role in the development of the new energy vehicle field. Otherwise, news about new energy vehicles catching fire will appear beside us from time to time, not only damaging citizens' property and personal safety but also causing people to resist new energy vehicles and hindering the development of the new energy industry.

[0031] Battery thermal runaway is one of the key issues in battery safety. If an electric vehicle battery catches fire after thermal runaway, and due to the rapid combustion and inconvenience of extinguishing the fire, the vehicle will basically be completely burned, even threatening personal safety. Therefore, how to ensure the safety of users and other property in the case of battery spontaneous combustion has also become one of the key research points in the industry.

[0032] To solve the technical problem in the prior art that it is impossible to quickly ensure the safety of users and other property in the case of battery spontaneous combustion, the present application provides a battery detachment system that can quickly ensure the safety of users and other property in the case of battery spontaneous combustion.

[0033] Figure 1 A battery detachment system provided by an embodiment of the present application. As shown in the figure, the battery detachment system includes a decision-making unit 102 and a battery detachment device 104. Among them, the decision-making unit 102 is used to obtain thermal runaway information and environmental perception data of a preset area where the vehicle body is located, and determine whether the battery detachment condition is met according to the thermal runaway information and the environmental perception data, and send an electrical signal to the battery detachment device 104 when the battery detachment condition is met; the battery detachment device 104 includes a fastening structure, a fuse structure, an explosion structure, a separable structure, and a battery fixing structure. The fuse structure, the explosion structure, and the separable structure are all arranged on the fastening structure. The battery fixing structure is connected to the vehicle body through the fastening structure. The fuse structure is connected to the explosion structure. The fuse structure detonates the explosion structure when receiving the electrical signal, and blows up the separable structure on the fastening structure, so that the battery detaches from the vehicle body.

[0034] In order to timely detect whether the battery will spontaneously combust, the battery detachment system provided by the present application includes a decision-making unit. The decision-making unit can timely obtain the thermal runaway information of the battery and the environmental perception data of the preset area where the vehicle body is located. When the thermal runaway information of the battery indicates that the battery has experienced thermal runaway, the decision-making unit needs to judge whether the current detachment condition is met according to the environmental perception data. Meeting the detachment condition can be understood as that the battery has experienced thermal runaway and there is a risk of imminent spontaneous combustion. Under the condition of ensuring the safety of the vehicle, the driver, and the surroundings, the current position of the vehicle is suitable for the operation of detaching the battery.

[0035] Optionally, most vehicles at present are equipped with an intelligent driving system. The decision-making unit can be directly deployed on the intelligent driving system without additional installation, thereby reducing the complexity and weight of the entire vehicle system. This not only helps to save space but also contributes to improving the stability and reliability of the entire vehicle system.

[0036] In order to complete the battery detachment as soon as possible when the battery detachment condition is met, the battery detachment system provided by the present application includes a battery detachment device. The battery detachment device specifically includes a fastening structure, a fuse structure, an explosion structure, a separable structure, and a battery fixing structure.

[0037]

[0038] ​The fuse structure is a key part of the battery detachment device that is responsible for receiving electrical signals and triggering an explosion. The fuse structure includes an ignition device and an external circuit, which are used to receive electrical signals from the decision-making module. When the fuse structure receives the electrical signal sent by the decision-making unit, it will quickly ignite the explosive in the connected explosive structure. The huge energy generated by the explosion of the explosive is directed to the separable structure, and the separable structure is damaged by local high temperature and high pressure. Since the separable structure connects the battery fixing structure to the battery detachment device, the disconnection of the separable structure can achieve the separation of the battery from the vehicle body.

[0039] Figure 2 As an optional connection schematic diagram of the battery and the vehicle body provided by this application, as shown in the figure, the frame-cross beam represents the vehicle body, and the battery (or battery pack) is fixed on the battery fixing structure of the battery detachment device. The battery and the vehicle body are connected together through the battery detachment device.

[0040] As an optional embodiment, the explosive structure is adjacent to the separable structure and is located in the same horizontal direction.

[0041] The separable structure can be made of the same material as the bolt, or other metal materials with similar mechanical properties. These materials usually have high strength and toughness to ensure that they can withstand the required loads under normal working conditions and can break smoothly during an explosion.

[0042] Specifically, when the fuse structure receives a signal and ignites the explosive, the explosive will explode quickly, generating high-temperature and high-pressure detonation products and shock waves. The explosive structure is adjacent to the separable structure and is located in the same horizontal direction. When the explosive structure explodes, the separable structure is disconnected synchronously, achieving the separation of the battery from the vehicle body.

[0043] The reaction time of the battery detachment device (i.e., the time from receiving the ignition signal to the fracture of the separable structure) can be precisely controlled through design. This controllability makes the battery detachment device very useful in scenarios where precise control of the separation time is required. If the battery experiences thermal runaway, measures can be taken in a timely manner to separate the battery.

[0044] Specification

[0045] As an optional embodiment, an explosive placement area is provided inside the explosive structure.

[0046] An explosive placement area is provided inside the explosive structure. The explosive can be a high-energy explosive, and the explosive is the core that generates the explosion energy.

[0047] The space size of the explosive placement area needs to be set according to the actual situation. The space size of the explosive placement area and the amount of explosives placed can be determined in advance through multiple tests. It is necessary to ensure the directional release of the explosive energy and that it does not affect other devices except the separable structure.

[0048] As an alternative embodiment, the battery is fixed to the battery fixing structure. If the separable structure breaks, both the battery fixing structure and the battery fall off the vehicle body.

[0049] The battery is pre-installed on the battery fixing structure and firmly fixed by bolts, buckles or other means. When necessary, the battery is quickly separated from the vehicle body by the breakage of the separable structure.

[0050] Due to the breakage and separation of the separable structure, the battery fixing structure is damaged or loses its fixing function on the battery, so that the battery can fall off.

[0051] The battery detachment device provided in this application can be an explosive bolt or other devices with the above functional principles. The fastening structure can include screws and nuts. The vehicle body cross beam and the battery fixing structure can be fixed together by screws and nuts.

[0052] Figure 3 The figure is a schematic structural diagram of a battery detachment device provided in this application. As shown in the figure, it includes a fuse structure 31, an explosive structure 32, a fastening structure 33, a separable structure 34, and a battery fixing structure 35. The fuse structure 31, the explosive structure 32, and the separable structure 34 are all arranged on the fastening structure 33. The fuse structure 31 is connected to the explosive structure 32. The explosive structure 32 is adjacent to the separable structure 34 and is located in the same horizontal direction. The battery fixing structure 35 is connected to the explosive structure 32 through the separable structure 34. A battery (pack) is fixed on the battery fixing structure 35. When the decision-making unit decides to detach the battery, it sends an electrical signal to the ignition device of the fuse structure. After ignition, the gunpowder explodes and disconnects the separable structure, thus separating the battery from the vehicle body and completing the detachment of the battery.

[0053] It should be noted that when the battery is approaching spontaneous combustion, it will be under high voltage. At this time, the ignition device and the decision-making unit of the vehicle must be connected to the small battery of the vehicle engine to ensure that it can be triggered.

[0054] As an alternative embodiment, the system further includes a battery thermal management unit. The battery thermal management unit is connected to the decision-making unit. The battery thermal management unit is used to send the thermal runaway information of the battery to the decision-making unit when it detects that the battery enters the thermal runaway state.

[0055] The battery thermal management unit monitors the temperature of the power battery in real time, accurately senses the temperature distribution inside the battery, and transmits data to the internal processor for analysis to determine whether the battery has entered a thermal runaway state. If the battery has entered a thermal runaway state, the battery's thermal runaway information is sent to the decision unit. The thermal runaway information includes the battery's temperature value, temperature change trend, battery status parameters and other information.

[0056] Optionally, in addition to monitoring the battery temperature, other key parameters of the battery may also be monitored, such as voltage, current, state of charge, etc., to comprehensively evaluate the working state of the battery.

[0057] Figure 4 This is a flow chart of the battery shedding method provided by the present application based on the battery shedding system. As shown in the figure, the thermal management module monitors whether the battery temperature is normal. If the battery temperature is too high and close to the spontaneous combustion temperature, the spontaneous combustion information is transmitted to the decision system (corresponding to the decision specification of the present application).

[0058] The intelligent driving system (corresponding to the intelligent driving unit of this application) is responsible for scanning environmental information. The decision-making system calls the environmental information of the intelligent driving system and determines whether the battery shedding conditions are met. If the battery shedding conditions are met, the driver is reminded and the battery is shedding is performed. If the battery shedding conditions are not met, the driver is reminded and the double flash and horn are turned on to unlock the car.

[0059] As an optional embodiment, the battery thermal management unit includes a temperature detection device, and the temperature detection device is used to monitor the real-time temperature value of the battery.

[0060] The temperature detection device (such as a temperature sensor) is used to detect the temperature of the battery and its surrounding environment. The location of the temperature detection device can be selected based on the thermal behavior characteristics of the battery and the expected thermal management requirements.

[0061] The temperature detection device can accurately detect the real-time temperature value of the battery and obtain the temperature change of the battery in time.

[0062] After the battery thermal management unit sends the thermal runaway information to the decision unit, the decision unit retrieves the environmental perception data from the intelligent driving unit to further determine whether the battery shedding conditions are met. If the battery shedding conditions are met, the battery shedding operation is performed and the first prompt information is sent to the driver to inform the driver that the battery is about to fall off. If the battery shedding conditions are met, the second prompt information for warning is sent to the driver to enable the driver to turn on the double flash and honk the horn to unlock in time.

[0063] The second prompt message is also used to prompt the driver to drive towards an open area within a short time. After receiving the second prompt message, the driver honks the horn while driving the vehicle towards the open area. When the vehicle is in the open area, the decision-making unit will receive new environmental perception data sent by the intelligent driving unit, indicating that the current condition meets the battery detachment condition. At this time, the battery detachment operation can be executed.

[0064] It should be noted that the vehicle system can judge the emergency level according to the current temperature change. If the emergency level is relatively low, the driver can be prompted to drive the vehicle towards an open area. If the emergency level is relatively high, the driver can get out of the vehicle in time and quickly evacuate the surrounding people to minimize the loss as much as possible.

[0065] As an optional embodiment, the system further includes an intelligent driving unit. The intelligent driving unit is connected to the decision-making unit. The intelligent driving unit is used to obtain the environmental perception data of the preset area where the vehicle body is located and send the environmental perception data to the decision-making unit. The environmental perception data includes the area image and environmental information of the preset area.

[0066] The intelligent driving unit is used to timely sense the interference object data (i.e., pedestrians, vehicles, and other objects) within the preset area where the vehicle is located and send it to the decision-making unit. If there is no interference object within the preset area, the battery detachment condition is met. If there is an interference object within the preset area, the battery detachment condition is not met.

[0067] The preset area can be a circle centered on the vehicle body with a preset length as the radius. This circular area is the preset area, and the preset length can be set according to the actual situation.

[0068] As an optional embodiment, the intelligent driving unit includes an image acquisition device. The image acquisition device is used to acquire the area image within the preset area, and the area image is used to identify the interference object data within the preset area.

[0069] This application provides a camera as the image acquisition device. The camera, through its optical lens and image sensor, captures the area image of the preset area where the vehicle is located in real time. By using image recognition technology, the area image captured by the camera can be analyzed, so as to accurately identify the objects, pedestrians, vehicles, etc. in the area image.

[0070] Specification

[0071] By acquiring the area image within the preset area and using image recognition technology to identify the interference object data therein, it provides important environmental perception and decision-making support for the intelligent driving system.

[0072] As an optional embodiment, the intelligent driving unit includes an environmental perception device. The environmental perception device is used to sense the environmental information of the preset area where the vehicle body is located, and the environmental information is used to identify the interference object data within the preset area.

[0073] The environmental information collected by the environmental sensing device is used to identify various interference objects in the preset area, including pedestrians, vehicles, obstacles, road signs, etc.

[0074] The environmental perception device provided in the present application can be a laser radar, which emits short and intense laser pulses. These pulses are sent to interference objects in the environment around the vehicle. When the laser pulse encounters an interference object, it will be reflected and received by the laser radar receiver. The receiver will capture the reflected laser signal and convert it into an electrical signal for processing. The time difference from the emission to the reception of the laser pulse is measured through the received signal, and this time difference is used to calculate the distance between the interference object and the laser radar. According to the distance between the interference object and the vehicle body, it is determined whether the interference object is located in a preset area.

[0075] It should be noted that the image acquisition device and environmental perception device involved in the present application are devices that come with the intelligent driving unit, and there is no need to reinstall new image acquisition devices and environmental perception devices in response to the battery detachment mechanism.

[0076] Figure 5 A schematic diagram of a battery shedding system provided for the present application, as shown in the figure, the battery shedding system includes a battery thermal management unit, an intelligent driving unit, a decision unit and a battery shedding device. The battery thermal management unit is connected to the decision unit and the battery. The battery thermal management unit is used to send the thermal runaway information of the battery to the decision unit when it detects that the battery enters a thermal runaway state. The intelligent driving unit is connected to the decision unit. The intelligent driving unit is used to obtain environmental perception data of a preset area where the vehicle body is located, and send the environmental perception data to the decision unit; the decision unit is used to determine whether the battery shedding conditions are met based on the thermal runaway information and the environmental perception data, and send an electrical signal to the battery shedding device when the battery shedding conditions are met; the battery shedding device performs a battery shedding operation when receiving the electrical signal.

[0077] The present application provides a battery shedding system in case of spontaneous combustion. When the battery temperature is too high and reaches the spontaneous combustion temperature, the decision processor obtains the intelligent driving module to perform surrounding environment modeling and analysis. When there are few pedestrians or vehicles around, an electrical signal is sent to ignite and disconnect the battery shedding device to separate the battery. The vehicle can use inertia to leave the battery after spontaneous combustion, keeping the vehicle body intact and protecting the personal safety of users on the vehicle. The decision unit and the intelligent driving unit in the battery shedding system can rely on the existing system for logical settings, which has the advantage of low cost. After shedding, the vehicle only needs to reinstall the battery, and no other damage will be caused to the vehicle.

[0078] An embodiment of the present application also provides a vehicle, comprising the above-mentioned battery shedding system.

[0079] The vehicle of this embodiment includes a battery detachment system, which includes a decision-making unit and a battery detachment device. First, the decision-making unit monitors whether the battery is in a thermal runaway state to determine whether the current conditions for battery detachment are met. When the conditions for battery detachment are met, an electrical signal is sent in a timely manner to detonate the explosive structure in the battery detachment device, thereby disconnecting the separable structure that connects the fuse structure and the battery fixing structure, so that the battery fixing structure, together with the battery, detaches from the vehicle body, avoiding damage to the vehicle and the driver caused by battery spontaneous combustion and solving the problem of being unable to quickly ensure the safety of users and other property in the event of battery spontaneous combustion.
