[0040] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the present application.

[0041] It should be noted that the terms "first", "second", etc. in the specification, claims and above-mentioned drawings of the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] In the prior art, based on a thin-film sensor to detect the deformation of the battery surface, and according to the degree of battery surface deformation and the number of charge and discharge cycles experienced by the battery after deformation, different levels of early warning control for the driver are carried out, and early warning can be realized. However, the feasibility of engineering implementation is not fully considered. In the invention embodiment, the vehicle controller / battery management system needs to record and store the time when the battery surface deformation occurs and the number of charge and discharge cycles experienced after the deformation. For actual commercial vehicles, after a long time of user use, the memory occupied by this information is immeasurable, so it does not have engineering feasibility.

[0043] In order to solve the problem of how to achieve early warning and prevention, the present application provides a method for processing battery collision. The method includes: a plurality of sensors can be arranged on the battery of the vehicle, and the positions of the plurality of sensors are different. In response to the battery on the vehicle being collided, obtain the collision information of the first sensor at the collided position and the operating parameters of the battery after being collided, and the collision information includes the voltage change information and / or current change information of the sensor. According to the collision information, determine the collision level of the battery being collided, and the collision level is proportional to the force of the vehicle battery being collided, and according to the battery operating parameters, determine the operating condition of the battery. Finally, according to the collision level and operating condition of the battery, perform corresponding warning processing.

[0044] For the convenience of understanding, the following specifically introduces a method for processing battery collision provided by the present application in conjunction with the accompanying drawings.

[0045] Figure 1It is a schematic framework diagram of a battery collision processing system shown according to an exemplary embodiment. As Figure 1 shown, the schematic framework diagram includes a vehicle battery, a collision detection sensor, a warning control system, a battery control system, a vehicle control system, an in-vehicle network terminal, and a cloud server.

[0046] Among them, a battery is installed on the vehicle, and the battery is used to provide energy for new energy vehicles. A battery protection case is installed outside the battery, which is used to fix and protect the battery.

[0047] The collision detection sensor (subsequently, for the convenience of description, simply referred to as the sensor) is used to detect whether there is a collision on the battery case and the degree of collision. The collision sensor can be an elastic wave sensor, and of course, it can also be other sensors, which are not limited here. Specifically, the sensor is used to be pasted on the bottom and side of the battery protection case to identify collision information according to physical characteristics.

[0048] In one example, as Figure 2 shown, it is a diagram of the paste positions of a battery collision detection sensor provided by an embodiment of the present application. A plurality of sensors are pasted on the battery surface and numbered to detect whether the battery is collided. For example, 1 sensor is pasted on the front and back of the battery respectively, numbered as front 1 and back 2; 2 sensors are pasted on the left and right sides of the battery respectively, numbered as side 3, side 4, side 5, and side 6; the surface area of the battery is relatively large, and a plurality of sensors are pasted, which are respectively bottom 7, bottom 8, bottom 9, bottom 10, bottom 11, and bottom 12, etc., which are not limited here.

[0049] Based on Figure 2 the technical solution shown, in an embodiment of the present application, the battery can be comprehensively covered by a plurality of sensors, and collision information can be detected in time when the battery collides.

[0050] The warning control system is used to receive the collision information of the collision detection sensor and judge the collision level and collision position of the battery on the vehicle.

[0051] The battery control system is used to detect the voltage, temperature, internal resistance, and current inside the battery, count the parameters of the battery, and determine the comprehensive state of the battery.

[0052] The vehicle control system (subsequently, for the convenience of description, simply referred to as the vehicle computer system) is used to receive the vehicle fault information that appears in the warning control system and the battery control system, comprehensively consider the current vehicle state, and perform different degrees of restriction processing on the vehicle according to the severity of the fault, such as limiting power, to ensure the safety of the vehicle.

[0053] The in-vehicle network terminal is used to receive the key parameter information of the vehicle controller and transmit it to the cloud server; the cloud server stores the received vehicle information, sets a warning algorithm, and judges whether a warning is needed according to the comprehensive state of the battery after a collision.

[0054] As Figure 3 shown, the flowchart of a method for handling battery collision provided by an embodiment of the present application is applied to a vehicle and includes the following S301 - S303.

[0055] S301. In response to the battery being collided, the vehicle-mounted system obtains the collision information of the first sensor at the collided position of the battery and the operating parameters after the battery is collided.

[0056] Among them, the collision information of the first sensor includes voltage change information and / or current change information; the operating parameters after the battery is collided include one or more of the output voltage, output current, battery temperature, and battery internal resistance of the battery.

[0057] Specifically, the sensor is internally composed of multiple small elastic piezoelectric induction elements. When a collision and extrusion occur, charges are generated on the surface of the elastic piezoelectric induction elements. After the charges are amplified and the impedance is transformed by a charge amplifier and a measurement circuit, they are converted into an electric quantity output, resulting in a change in the voltage and / or current of the sensor when pressure is applied. The sensor detects the collision information based on this physical property.

[0058] In a possible implementation manner, after a collision occurs, the vehicle-mounted system detects the operating parameters of the battery through the battery control system.

[0059] In another possible implementation manner, according to the identifier of the first sensor and a preset three-dimensional space model, the detection area of the first sensor is determined; the preset three-dimensional space model is used to reflect the detection area of each sensor among multiple sensors; according to the detection area of the first sensor, the collided position of the battery is determined.

[0060] In an example, the present application establishes a three-dimensional space model of the battery with one of the vertices of the battery as the original coordinate, and establishes the position coordinates and coverage range coordinates of multiple sensors in the three-dimensional space model. As Figure 4 shown, a battery collision detection position map provided by an embodiment of the present application is shown. Taking the bottom 7, bottom 8, bottom 10, and bottom 11 sensors as examples, the battery collision position is described in detail in a two-dimensional space. Taking the center point as the coordinate O, the bottom 7 sensor is set as Cn7, and the covered detection area is On7. The bottom 8 sensor is set as Cn8, and the covered detection area is On8. Similarly, numbering is carried out in turn. When only Cn7 detects a change in voltage and / or current value, according to the preset coordinate position, the collision position information is determined to be the range On7 covered by Cn7. When both Cn7 and Cn8 detect a change in voltage or current, according to the preset coordinate position, the collision position information is determined to be the intersection of Cn7 and Cn8. Therefore, the collision position range of the battery can be judged according to the detection range of the sensor.

[0061] Specifically, there are 4 small elastic piezoelectric sensing elements inside each sensor, and the monitoring ranges of each elastic piezoelectric sensing element are different. For example, if the sensor is Cn, the elastic piezoelectric sensing elements are Cn1, Cn2, Cn3, and Cn4 respectively. The sensor Cn can more accurately determine the detailed position of the collision according to the detected numbers of the specific elastic piezoelectric sensing elements.

[0062] In an example, if only Cn1 among the four elastic piezoelectric sensing elements detects a change in voltage and / or current value, according to the preset coordinate information of the sensing element Cn1 and its covered detection coordinate area On1, the position information of the collision is determined to be the detection coordinate area On1 covered by Cn1. If it is detected that the output voltage and / or current values of Cn2 and Cn3 change, according to the preset coordinate information of the sensing elements Cn2 and Cn3 and their covered detection coordinate areas, the position information of the collision is determined to be in the overlapping area of the two. If Cn1, Cn2, Cn3, and Cn4 simultaneously detect a change in voltage and / or current value, according to the preset coordinate information of the four sensing elements and their covered detection coordinate areas, the position information of the collision is determined to be in the overlapping area of the four. Therefore, the position information of the battery collision can be obtained more accurately.

[0063] Through the above technical solution, the vehicle-mounted system can detect whether a collision occurs through the voltage and / or current change of the sensor, and determine the collision level through the voltage and / or current value of the sensor after a collision, determine the battery operation condition through the battery operation parameters, and determine the collision position through the detection range of the sensor. Therefore, the battery abnormality and collision position can be accurately located.

[0064] S302. The vehicle-mounted system determines the collision level of the battery being collided according to the collision information, and determines the operation condition of the battery according to the operation parameters.

[0065] Among them, the collision level is proportional to the force of the vehicle battery being collided, and the higher the collision level, the more serious the collision degree of the battery.

[0066] In a possible implementation manner, after the vehicle-mounted system obtains the voltage change information and / or current change information of the sensor, it determines the battery collision level according to the voltage and / or current value. If the voltage and / or current value of the sensor is less than M, it is determined as a level 1 collision; if the voltage and / or current value of the sensor is greater than M and less than N, it is determined as a level 2 collision; if the voltage and / or current value of the sensor is greater than N and less than K, it is determined as a level 3 collision; if the voltage and / or current value of the sensor is greater than K, it is determined as a level 4 collision. Among them, M, N, and K are all positive numbers, and M < N < K.

[0067] In another possible implementation, after the battery collides, the operating parameters of the battery are detected. The operating condition of the battery is judged according to the battery operating parameters. When the change value of the operating parameters exceeds the preset threshold, it is determined that the battery is operating abnormally; when the change value of the operating parameters does not exceed the preset threshold, it is determined that the battery is operating normally.

[0068] For example, during normal driving, the battery temperature remains within the range of 10 degrees to 35 degrees. After the vehicle-mounted system detects a battery collision through a sensor, it synchronously detects the battery parameters. If it detects that the battery temperature reaches 40 degrees or above, it is determined that the battery is operating abnormally. Otherwise, the battery is operating in a normal state.

[0069] The internal resistance of the battery usually remains below 10 milliohms during driving. After the vehicle-mounted system detects a battery collision through a sensor, it synchronously detects the battery parameters. If it detects that the internal resistance of the battery reaches 10 milliohms or above, it is determined that the battery is operating abnormally. Otherwise, the battery is operating in a normal state.

[0070] Through the above technical solution, the battery collision level can be determined by the sensor voltage and / or current value, and the battery operating condition can be determined by the battery operating parameters. Therefore, when a collision occurs, the abnormal condition of the battery can be accurately detected.

[0071] S303. According to the collision level and operating condition of the battery, the vehicle-mounted system performs corresponding warning processing.

[0072] Among them, the warning processing includes displaying the collision location, prompting the collision degree, restricting the battery power, and forced power-off processing, etc. Of course, there can also be other processing, which is not limited here.

[0073] In a possible implementation, the vehicle-mounted system sends the collision level and operating condition of the battery to the cloud server. After receiving the collision level and operating condition of the battery from the vehicle-mounted system, the cloud server can determine the instruction information according to the battery collision level and operating condition, and send the instruction information to the vehicle-mounted system. The instruction information is used to indicate the control operations that the vehicle needs to perform.

[0074] Correspondingly, the vehicle-mounted system receives the instruction information from the cloud server and executes the control operations in response to the instruction information.

[0075] In an example, when the battery collision level is less than the preset level and the battery is operating normally, the cloud server receives the collision information of the vehicle-mounted system and counts the number of times the battery has been collided. When the number of times the battery has been collided exceeds the preset number of times, an alarm message is sent to the vehicle-mounted system, and the alarm message is used to indicate the detection of the battery performance.

[0076] In another example, when the battery collision level is greater than a preset level, or when the battery shows an abnormality, the in-vehicle system receives the command information from the cloud server to limit the output power of the battery or force the vehicle to power off.

[0077] Specifically, as Figure 5 shown, a battery collision detection and early warning processing diagram provided by an embodiment of the present application. After receiving the collision information, the in-vehicle system receives the command information from the cloud server for corresponding early warning processing according to different collision levels. The following details the different processing methods for different collision levels.

[0078] 1. When the collision level is level 1, the in-vehicle system detects whether there is a battery abnormality through the battery control system. If there is no battery abnormality, the early warning information is transmitted to the cloud server for storage via the in-vehicle network terminal. The cloud server counts the early warning events. When the number of early warning times exceeds a certain value A, a message is pushed indicating that the battery has been collided and may be damaged, and the battery needs to be detected. If there is a battery abnormality, the battery abnormality situation is pushed.

[0079] 2. When the collision level is level 2, the in-vehicle system detects whether there is a battery abnormality through the battery control system. If there is no battery abnormality, the early warning information is transmitted to the cloud server for storage via the in-vehicle network terminal. The cloud server counts the early warning events. When the number of early warning times exceeds a certain value B (B < A), a message is pushed indicating that the battery has been collided and may be damaged, and the battery needs to be detected. If there is a battery abnormality, according to the early warning information, the battery collision position is marked and the battery abnormality situation is presented in the form of a picture or an animation to prompt the user that there has been a collision.

[0080] 3. When the collision level is level 3, the in-vehicle system detects whether there is a battery abnormality through the battery control system. If there is no battery abnormality, according to the early warning information, the battery collision position is marked, and the battery abnormality situation is presented in the form of a picture or an animation to prompt the user that there has been a collision. At the same time, the output power of the battery is limited to C and a prompt is given. The prompt information includes: For safety reasons, it is recommended to go to the repair immediately after this use. When the in-vehicle system detects that the power gear changes from ON to OFF after the prompt, the vehicle will be restricted from powering on.

[0081] If the battery shows an anomaly, based on the warning information, mark the battery collision location and present the battery anomaly in the form of a picture or animation to prompt the user of a collision. At the same time, limit the battery output power to C and give a prompt. The prompt information includes: For safety reasons, it is recommended to immediately pull over to the side of the road for inspection and no longer use the vehicle. After the in-vehicle system gives the prompt, it checks whether the vehicle power gear changes from ON to OFF within a certain period of time. If it does not change to OFF, limit the battery output power to D (D < C) and give another prompt. The prompt information includes: The vehicle battery has collided. For safety reasons, please immediately pull over to the side of the road for inspection and no longer use the vehicle. After repeating the prompt three times and still not detecting that the vehicle power gear is OFF, force the vehicle to power off.

[0082] 4. When the collision level is 4 or higher, based on the warning information, mark the battery collision location and present the battery anomaly in the form of a picture or animation to prompt the user of a collision. At the same time, limit the battery output power to C and give a prompt. The prompt information includes: For safety reasons, it is recommended to immediately pull over to the side of the road for inspection and no longer use the vehicle. After the in-vehicle system gives the prompt, it checks whether the vehicle power gear changes from ON to OFF within a certain period of time. If it does not change to OFF, limit the battery output power to D (D < C) and give another prompt. The prompt information includes: The vehicle battery has collided. For safety reasons, please immediately pull over to the side of the road for inspection and no longer use the vehicle. After repeating the prompt three times and still not detecting that the vehicle power gear is OFF, force the vehicle to power off.

[0083] Through the above technical solutions, after detecting that the vehicle has collided, different treatments are carried out for different collision levels. When the collision level is relatively small, the battery collision location, collision level, and anomaly can be displayed and a prompt is given. The prompt information includes timely detecting the battery, etc. When the collision level is serious, the in-vehicle system controls the vehicle by limiting the output power of the vehicle battery or forcing it to power off to ensure the safety of the vehicle. Therefore, the safety of the vehicle can be improved by timely warning and prevention of the vehicle battery.

[0084] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method.
