[0041] Reference Figure 1 , Figure 1 This is an optional structural diagram of a battery disposal system provided in an embodiment of the present application. The system may include:

[0042] a monitoring module, configured to monitor vehicle battery status information and vehicle status information, and generate a battery usage risk signal when determining, based on the vehicle battery status information, that a preset battery usage risk exists, wherein the battery usage risk is a risk of causing battery spontaneous combustion;

[0043] a control module configured to receive a battery usage risk signal and vehicle status information, generate a battery abandonment strategy based on the vehicle status information, and generate a battery abandonment instruction based on the battery abandonment strategy, wherein the battery abandonment strategy includes an angle and a force for abandoning the vehicle battery;

[0044] The battery locking module is used to fix the vehicle battery, receive the battery abandonment instruction, and abandon the vehicle battery according to the battery abandonment strategy.

[0045] In some embodiments, the monitoring module includes a data acquisition unit and a data analysis unit.

[0046] a data acquisition unit for acquiring continuous time series vehicle battery status information, including vehicle battery temperature, vehicle battery voltage, and vehicle battery current;

[0047] The data analysis unit is used to analyze the vehicle battery status information in a continuous time series using a neural network model or a numerical analysis method to generate a battery temperature prediction result. When it is determined that the vehicle battery has a battery usage risk based on the battery temperature prediction result, a battery usage risk signal is generated.

[0048] In some embodiments, vehicle battery status information includes but is not limited to vehicle battery temperature, vehicle battery voltage, vehicle battery current, vehicle battery internal resistance, vehicle battery power, vehicle battery cooling system status, vehicle battery smoke detection system status, vehicle battery gas sensing status and vehicle battery pressure, etc.

[0049] In some embodiments, the control module includes a policy generation unit.

[0050] The data acquisition unit is further configured to collect vehicle status information, including the current vehicle surrounding environment, the current occupant status, and the current vehicle driving status. The current occupant status includes the seating status and seating position of the occupants, the seating status includes a stationary state and a moving state, and the current vehicle driving status includes the vehicle's speed, current vehicle position, and vehicle driving direction.

[0051] The strategy generation unit is used to determine the target abandonment location from the current vehicle surrounding environment based on the vehicle status information, determine the throwing angle and throwing force of the vehicle battery according to the current vehicle driving status and the target abandonment location, and generate a battery abandonment strategy based on the throwing angle and throwing force.

[0052] In some embodiments, the data acquisition unit collects vehicle status information through an IMU inertial navigation device, a gyroscope, a GPS, a camera, a millimeter-wave radar, an ultrasonic radar, etc. Optionally, the occupant status and seating position of the current occupant in the vehicle are determined by:

[0053] 1) Using the DMS camera inside the vehicle and the AI ​​image recognition model, the system identifies the image and determines whether there are any moving objects in the image. In other words, whether there are any changes in the pixels of the people in the image. If there are no changes in the pixels of the people, it means that the occupants in the vehicle are stationary. Otherwise, the occupants in the vehicle are in motion.

[0054] 2) Use sensors such as millimeter-wave radar inside the vehicle to confirm whether the occupants are stationary. If the continuous inactivity time exceeds a preset time threshold, it indicates that the occupants are stationary; otherwise, the occupants are in motion;

[0055] 3) Use the seat pressure sensor to detect whether the seat is occupied and the current seating position of the passengers in the car. At the same time, the seating status of the passengers in the car can be confirmed by prompting the passengers to click the confirmation button on the large display screen of the vehicle control system or perform voice recognition.

[0056] In some embodiments, optionally, based on the current vehicle surroundings, it is determined whether the surrounding road surface is a curb or there are other obstacles that prevent the battery from being thrown out from the side. At this time, a set of sides from which the battery can be thrown out is obtained. For example, when a chain rear-end collision between the front and rear vehicles causes a risk of spontaneous combustion of the battery, the battery can be thrown out on the left and right sides of the vehicle. If the front, rear, left, and right sides of the vehicle cannot be thrown out, the battery can be thrown out on the default sides: the front and rear sides of the vehicle.

[0057] The priority of the battery ejection bottom is determined based on the battery ejectable surface, the current position and status of the occupants in the vehicle. For example, the priority of left and right ejection is calculated as follows: the number of occupants on different sides is determined based on the current position of the occupants in the vehicle. Based on the number and status of the occupants on different sides, corresponding scores are assigned to the corresponding sides. The battery is ejected from the side with the higher score. A specific example is as follows:

[0058] 1) Assuming there is a driver on the left side of the car and the state is moving, the number of passengers on the left side is 1 point, and the moving state is 2 points, so the left side has a total of 3 points. Assuming there is a passenger on the right side of the car and the passenger is stationary, the number of passengers on the right side is 1 point, and the stationary state is 1.5 points, so the right side has a total of 2.5 points. At this time, the vehicle battery is thrown to the left;

[0059] 2) If there is a driver on the left side of the car, it gets 1 point; if there is no one on the right side, it gets 5 points (5 points is the default). In this case, the right side scores higher and the vehicle battery is thrown to the right.

[0060] In some embodiments, the battery locking module includes a power-on state and a power-off state, and the battery locking module includes a fastening unit and a pneumatic unit;

[0061] A fastening unit, used to carry and fix the vehicle battery when the power is off, and stop fixing the vehicle battery when the power is on;

[0062] The pneumatic unit is used to release explosive gas when powered on, output a target thrust corresponding to the throwing force, and use the target thrust to push the vehicle battery out at a throwing angle.

[0063] In some embodiments, the pneumatic unit includes an ignition device and a cylinder device.

[0064] The ignition device is connected to the cylinder device and is used to provide heat energy to the cylinder device;

[0065] The cylinder device is used to control the intake volume of the explosion gas according to the target thrust, and utilizes the ignition device to ignite and burn the explosion gas to output the target thrust.

[0066] In some embodiments, reference Figure 2 , Figure 2This is a schematic diagram of an optional installation position of the pneumatic unit in an embodiment of the present application, where A is the installable area of ​​the pneumatic unit, B is the installation area of ​​the vehicle battery, and C is the vehicle chassis. The pneumatic unit and the vehicle battery are both installed in the vehicle chassis. The pneumatic unit is not installed in the center of the battery, but in a non-center position. In this way, when the explosive gas is released, a lateral thrust is generated, so that the vehicle can still be thrown out normally when it is hit and overturns or rolls.

[0067] Reference Figure 3 , Figure 3 This is a schematic diagram of an optional installation structure of the pneumatic unit in an embodiment of the present application, wherein the vehicle battery 1 is hoisted on the chassis 2, the pneumatic unit 3 is arranged between the vehicle battery 1 and the chassis 2, and the pneumatic unit 3 includes a thrust base plate 4, a cylinder device 5 and an ignition device 6.

[0068] In some embodiments, the fastening unit includes a fastening device, a heating device, and an energy storage device.

[0069] A fastening device for carrying and securing the vehicle battery when the power is off and for releasing the vehicle battery from being secured when the power is on;

[0070] An energy storage device, used for providing electrical energy to the heating device when powered on;

[0071] The heating device is arranged in the fastening device and connected to the energy storage device. When the power is on, it receives the electric energy provided by the energy storage device, uses the electric energy to generate heat, and uses the heat to heat the fastening device, thereby melting the fastening device so that the fastening device stops fixing the vehicle battery.

[0072] In some embodiments, optionally, in the unlocked state, the time t1 required for the heating wire to heat the fastening device and melt it is calculated based on the current temperature C1 of the fastening device, the melting temperature C2, the heating power of the heating wire and the specific heat capacity of the material of the fastening device. At time t1, the explosive gas is released through the pneumatic unit, and the vehicle battery is pushed out at a throwing angle using the target thrust.

[0073] In some embodiments, optionally, the fastening device is a bolt or a clip, and the heating device is a heating wire. A heating device is added to the fastening device, and the heating device is connected to the energy storage device through a power supply line. The energy storage device can be a vehicle battery or capacitor or other device that can store a certain amount of electricity. The power supply line is made of fireproof materials, including but not limited to high-temperature resistant insulating materials, high-temperature resistant conductive materials, etc.

[0074] The fastening device is made of heat-deformable materials, including but not limited to the following heat-deformable materials:

[0075] Shape Memory Alloys (SMAs): Nickel-titanium alloy (Ni-Ti alloy, also known as Nitinol), this alloy can be deformed at lower temperatures, but when heated to a specific temperature (usually above 100 degrees), it will return to a preset shape; Copper-aluminum-nickel alloy (Cu-Al-Ni alloy), this alloy also has a shape memory effect and can return to its original shape at a specific temperature.

[0076] Superalloys: Nickel-based superalloys have good oxidation resistance and hot corrosion resistance at high temperatures, but may creep and deform at extremely high temperatures; High-speed steel (HSS) has high hardness at 100 degrees and is suitable for use as cutting tools, but may soften above 200 degrees, resulting in a decrease in hardness and change in shape.

[0077] Plastics and polymers: thermoplastics, such as polyimide (PI), polyphenylene sulfide (PPS), etc.

[0078] Ceramic materials: Certain high-temperature ceramics. Although ceramics are generally very hard and stable at high temperatures, some types undergo thermal expansion and microstructural changes at high temperatures, affecting their shape and size.

[0079] It should be noted that the above-mentioned materials that deform under heat are examples, and the application of materials with such characteristics is still within the scope of protection of this patent.

[0080] In some embodiments, when powered on, the heating wire in the fastening device receives electrical energy provided by the energy storage device to heat the fastening device. The fastening device loses its fastening force due to heat, thereby melting and losing its bearing and fixing function on the vehicle battery.

[0081] In some embodiments, the data analysis unit is used to obtain a preset sliding time window, dynamically extract the vehicle battery status information corresponding to the sliding time window from the vehicle battery status information in a continuous time series for analysis, and determine the battery temperature average and battery temperature standard deviation within the sliding time window. When the battery temperature average is greater than a given temperature threshold and the battery temperature standard deviation is greater than a given standard deviation threshold, it is determined that there is a battery usage risk for the vehicle battery, and a battery usage risk signal is generated.

[0082] In some embodiments, for example, assuming that the continuous time series is 0s to 100s and the sliding time window is 10s, the battery temperature average value and the battery temperature standard deviation in each sliding time window are calculated, such as the battery temperature average value and the battery temperature standard deviation from 0s to 10s and the battery temperature average value and the battery temperature standard deviation from 10s to 20s, etc. When the battery temperature average value is greater than a given temperature threshold and the battery temperature standard deviation is greater than a given standard deviation threshold, it is determined that the vehicle battery has a battery usage risk. For example, when the battery temperature average value from 0s to 10s is greater than a given temperature threshold and the battery temperature standard deviation from 0s to 10s is greater than a given standard deviation threshold, then from 0s to 10s, it is determined that the vehicle battery has a battery usage risk.

[0083] In some embodiments, a data analysis unit is used to obtain a battery temperature prediction model, input the vehicle battery status information of a continuous time series into the battery temperature prediction model, and use the battery temperature prediction model to output the battery temperature prediction results, including the battery predicted temperature, the battery predicted voltage, and the battery predicted current, and generate a battery spontaneous combustion risk probability based on the battery temperature prediction results. When the battery spontaneous combustion risk probability is greater than a given probability threshold, it is determined that there is a battery usage risk for the vehicle battery, and a battery usage risk signal is generated; the battery temperature prediction model is trained through a sample data set, and the sample data set includes multiple vehicle battery status information with spontaneous combustion risk labels, and the spontaneous combustion risk labels include the presence of a battery spontaneous combustion risk and the absence of a battery spontaneous combustion risk.

[0084] In some embodiments, the battery temperature prediction model is a feedforward neural network, including an input layer, a hidden layer, and an output layer. The battery temperature prediction model is trained using a sample data set until the accuracy of the output result is higher than a given threshold, and then the training of the battery temperature prediction model is stopped. The battery temperature prediction result output by the battery temperature prediction model includes the battery predicted temperature, the battery predicted voltage, the battery predicted current, the battery spontaneous combustion risk probability, and the battery spontaneous combustion risk determination result. When the battery spontaneous combustion risk probability is greater than the given probability threshold, the battery spontaneous combustion risk determination result output by the battery temperature prediction model is that the battery has a spontaneous combustion risk.

[0085] Optionally, some sample data in the sample data set are shown in Table 1 below:
