[0002] With electric vehicles gaining increasing market share, the safety of their battery packs is crucial. Because they are typically mounted underneath the vehicle, they are susceptible to collisions and other issues during vehicle operation. Collisions involving electric vehicle battery packs are extremely dangerous. Deformation can compromise the pack's airtightness, leading to short circuits and even thermal runaway caused by water exposure.

[0003] Currently, collision monitoring of battery packs is usually performed based on collision sensors. However, there may be situations where the battery pack is hit but not deformed. Therefore, monitoring based on collision sensors has the problems of frequent alarms and false detections. Summary of the Invention

[0027] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs.

[0029] Figure 1 This is a flow chart of a battery pack collision monitoring method provided in an embodiment of the present application. This method is mainly applicable to monitoring whether the bottom of a vehicle's battery pack is deformed by a collision. This method can be executed by a battery pack collision monitoring device, which can be implemented in software and / or hardware and can be configured in an electronic device. Figure 1 As shown, the method may specifically include the following steps:

[0030] S110: Acquire the signal receiving status of the signal receiver corresponding to each signal transmitter.

[0031] Among them, the signal transmitter is used to transmit signals in a certain direction, and the signal receiver is used to receive the signals transmitted by the signal transmitter. Therefore, the signal transmitter and the signal receiver can be used in pairs. The signal reception status can be used to describe whether the signal receiver has received the signal and whether the signal has been fully received, for example, it can include received and not received. Each signal transmitter and each signal receiver are installed on the frame of the signal detection system inside the battery pack, and the signal detection system is arranged adjacent to the bottom guard plate of the battery pack. The signal transmitter and the signal receiver are respectively arranged on the relative frames along the first direction, and the signal transmitter and the signal receiver are respectively arranged on the relative frames along the second direction, and the first direction and the second direction intersect. It can be understood that the signal detection system has four frames corresponding to the bottom guard plate of the battery pack, so it can be installed on the bottom guard plate, and multiple pairs of signal transmitters and signal receivers are arranged on the relative frames of the signal detection system to identify the collision situation of the battery pack through the signal reception status.

[0032] The signal transmitter and signal receiver can be installed on opposite frames, and the line connecting the corresponding signal transmitter and signal receiver can be perpendicular to the frame or not. As long as the signal transmitter and signal receiver are installed in a corresponding manner and the signal beam emitted by each signal transmitter can cover the plane formed by each frame, the signal beam emission angle of the signal transmitter can be adjusted according to the position of the signal receiver corresponding to the signal transmitter.

[0033] Specifically, after each signal transmitter on the signal detection system is activated, it can transmit a signal beam to the opposite side, and the signal receiver corresponding to each signal transmitter can receive the signal beam without obstruction. In addition, the signal receiving status of each signal transmitter can be obtained.

[0034] Optionally, the signal transmitter is a light transmitter or an ultrasonic transmitter. If the signal transmitter is a light transmitter, the signal receiver is a light receiver; if the signal transmitter is an ultrasonic transmitter, the signal receiver is an ultrasonic receiver.

[0035] Specifically, a light transmitter can emit a light beam, and a light receiver corresponding to the light transmitter can receive the light beam to obtain a signal reception status corresponding to the light receiver. An ultrasonic transmitter can emit an ultrasonic beam, and a ultrasonic receiver corresponding to the ultrasonic transmitter can receive the ultrasonic beam to obtain a signal reception status corresponding to the ultrasonic receiver.

[0036] S120 : Determine the collision condition of the battery pack according to the reception status of each signal.

[0037] The collision condition may be used to describe whether the bottom of the battery pack is deformed due to the collision, that is, bulges toward the inside of the battery pack.

[0038] Specifically, if each signal reception status indicates that each signal receiver has received a signal beam transmitted by the corresponding signal transmitter, then there is no obstacle blocking the propagation of the signal beam, and therefore, it can be determined that the battery pack has not collided. Otherwise, it indicates that there is an obstacle blocking the propagation of the signal beam, and it can be determined that a collision has occurred.

[0039] Based on the above example, the collision condition of the battery pack can be determined according to the signal reception status in the following manner:

[0040] If the signal reception statuses are all received, it is determined that the collision condition of the battery pack is not a collision; if there is a signal reception status that is not received, it is determined that the collision condition of the battery pack is a collision.

[0041] Specifically, if all signal reception states are "Received," it indicates that the signal beam transmitted by each signal transmitter is received by the corresponding signal receiver. Therefore, it can be assumed that there are no obstacles blocking the signal beam during propagation, and therefore, the battery pack collision condition can be determined as "No collision has occurred." If a signal reception state is "Not Received," it indicates that the signal beam transmitted by at least one signal transmitter is blocked. Therefore, it can be assumed that there is an obstacle blocking the signal beam during propagation, possibly due to a bump on the bottom of the battery pack caused by the collision. Therefore, the battery pack collision condition can be determined as "A collision has occurred."

[0042] S130 : When the collision situation indicates that a collision has occurred, determine a collision position, generate battery pack collision prompt information according to the collision position, and send the battery pack collision prompt information to a display device.

[0043] The collision location may be the location where the bottom of the battery pack (such as a bottom guard plate or bottom plate) is deformed. The battery pack collision prompt information may be information used to notify the user that the battery pack has collided. The display device may be a device such as a vehicle dashboard or smart display screen that displays various information.

[0044] Specifically, if a collision has occurred, a user alert is issued to facilitate timely action to avoid danger. Furthermore, based on the signal reception status, it is possible to determine which signal beams were blocked by the bumps generated by the collision, thereby determining the collision location. Furthermore, based on the collision information, a battery pack collision warning message is generated, such as: "Battery pack deformed due to collision at position XXX, please address it promptly." This battery pack collision warning message is then transmitted to a display device for display, allowing users, particularly drivers, to promptly view the message and repair or replace the battery pack.

[0045] The battery pack collision monitoring method provided in this embodiment obtains the signal reception status of the signal receiver corresponding to each signal transmitter to determine whether each signal receiver has received the corresponding signal beam to judge whether the signal beam is blocked, and then determines the collision situation of the battery pack according to each signal reception status. When the collision situation is that a collision has occurred, the specific collision position is determined to generate battery pack collision prompt information, and the battery pack collision prompt information is sent to the display device to prompt the user to pay attention to the battery pack collision situation and intuitively display the collision position, thereby realizing simple and accurate monitoring of the collision at the bottom of the battery pack, avoiding damage to the battery pack or even thermal runaway.

[0046] Figure 2This is a flowchart of another battery pack collision monitoring method provided in an embodiment of the present application. Based on the above embodiments, an exemplary method for determining the collision position is optionally provided. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method may specifically include the following steps:

[0047] S210: Acquire the signal receiving status of the signal receiver corresponding to each signal transmitter.

[0048] Before obtaining the signal reception status of the signal receiver corresponding to each signal transmitter, it is necessary to start each signal transmitter and each signal receiver. This can be achieved in any of the following ways:

[0049] Method 1: Activate each signal transmitter and each signal receiver according to a preset period.

[0050] The preset period may be a pre-set period for detecting whether a collision occurs in the battery pack.

[0051] Specifically, timing is started after each collision detection of the battery pack. When the timing reaches a preset period, each signal transmitter and each signal receiver is started, and timing is restarted after the collision detection of the battery pack to facilitate subsequent monitoring of the battery pack.

[0052] Method 2: When it is detected that the preset journey has been completed, each signal transmitter and each signal receiver are activated.

[0053] The preset itinerary may be a navigation route pre-set when the vehicle is started.

[0054] Specifically, after the vehicle is started, the driver can drive according to the pre-set navigation route. When it is detected that the preset journey has been completed, it indicates that the vehicle has arrived at the destination. At this time, the collision condition of the battery pack can be detected by starting each signal transmitter and each signal receiver, so that the battery pack can be troubleshooted at the end of each journey.

[0055] Method 3: When it is detected that the battery pack detection function is triggered, each signal transmitter and each signal receiver are started.

[0056] The battery pack detection function may be a function for detecting whether the bottom of the battery pack is deformed by a collision.

[0057] Specifically, when the user needs to test the battery pack, they can trigger the battery pack test function by clicking the battery pack test control on the vehicle or mobile terminal. When the battery pack test function is triggered, it is necessary to detect whether the bottom of the battery pack has been deformed due to the collision, and thus activate each signal transmitter and each signal receiver.

[0058] S220 : Determine the collision condition of the battery pack according to the reception status of each signal.

[0059] S230: When the collision situation is that a collision has occurred, determine the collision position according to the position of the signal receiver whose signal receiving state is not receiving and the position of the signal transmitter corresponding to the signal receiver whose signal receiving state is not receiving.

[0060] Specifically, if a collision has occurred, the location of the deformation caused by the collision can be further determined. Lines are drawn between the positions of the signal receivers corresponding to each group whose signal reception status is not received and the positions of the signal transmitters corresponding to the signal receivers whose signal reception status is not received. The intersection of the lines can be used as the collision location.

[0061] Based on the above example, the collision location can be determined in the following way:

[0062] For each signal receiver whose signal receiving state is not receiving, a target signal beam is determined according to the signal transmitter corresponding to the signal receiver whose signal receiving state is not receiving; and overlapping positions between at least two target signal beams are determined as collision positions.

[0063] The target signal beam may be a signal beam emitted by a signal receiver whose signal receiving state is not received.

[0064] Specifically, for each signal receiver with a signal reception status of "no reception," the signal transmitter corresponding to that signal receiver can be determined. It can be assumed that the signal beam emitted by that signal transmitter was not received by the corresponding signal receiver, and therefore, the signal beam emitted by that signal transmitter is determined to be the target signal beam. Because the protrusion on the bottom of the battery pack blocks signal transmission, obstruction occurs in more than one direction. Therefore, it can be determined that there are at least two intersecting target signal beams. Based on this, the overlapping position between the at least two target signal beams can be determined as the collision position, which is used to mark the position of the protrusion on the bottom of the battery pack.

[0065] S240 : Generate battery pack collision prompt information according to the collision position, and send the battery pack collision prompt information to a display device.

[0066] Specifically, when generating battery pack collision prompt information, the collision location can be added thereto and sent to a display device, reminding the user that the battery pack is deformed due to the collision while prompting the location of the deformation, so that the user can quickly and accurately determine the collision problem of the battery pack.

[0067] Optionally, in order to improve the intuitiveness of the prompt, it is possible to: generate a bottom guard plate collision image based on the collision position and a preset battery pack bottom guard plate image, and send the bottom guard plate collision image to a display device.

[0068] The preset battery pack bottom guard plate image may be a plane or three-dimensional image simulating the battery pack bottom guard plate, and the bottom guard plate collision image may be an image after the collision position is marked in the preset battery pack bottom guard plate image.

[0069] Specifically, the preset battery pack bottom guard plate image can be a simulated image generated based on the actual battery pack bottom guard plate. The collision location is annotated in the preset battery pack bottom guard plate image to generate a bottom guard plate collision image that intuitively displays the collision location. The bottom guard plate collision image is then sent to a display device to alert the user and enhance the user's intuitiveness in identifying the collision location.

[0070] The battery pack collision monitoring method provided in this embodiment determines the collision position according to the position of the signal receiver whose signal reception status is not received and the position of the signal transmitter corresponding to the signal receiver when the collision situation is that a collision has occurred. Then, battery pack collision prompt information is generated according to the collision position, and the battery pack collision prompt information is sent to the display device, thereby achieving precise positioning of the collision at the bottom of the battery pack, facilitating users to perform repairs quickly and accurately, and avoiding damage to the battery pack or even thermal runaway.

[0071] Figure 3 A structural schematic diagram of a battery pack provided in an embodiment of the present application includes: a signal detection system.

[0072] The signal detection system is located adjacent to the bottom guard plate of the battery pack. Optionally, the signal detection system can be located in the gap between the bottom guard plate of the battery pack and the water cooling plate. Figure 4 shown.

[0073] Figure 5 The structural diagram of a signal detection system provided in an embodiment of the present application includes: a signal transmitter, a signal receiver and a frame. Figure 5 As shown, the solid circle represents the signal transmitter, the hollow circle represents the signal receiver, the solid line with the arrow represents the signal beam, and the solid line without the arrow represents the border.

[0074] Among them, each signal transmitter and each signal receiver are installed on the frame, the signal transmitter and the signal receiver are respectively arranged on opposite frames along the first direction, and the signal transmitter and the signal receiver are respectively arranged on opposite frames along the second direction, and the first direction and the second direction intersect.

[0075] It can be understood that the accuracy of determining the collision position of the battery pack based on the signal detection system is related to the settings of the signal transmitter and the signal receiver. The denser the settings of the signal transmitter and the signal receiver, the higher the accuracy of the collision position of the battery pack.

[0076] The battery pack of the above embodiment is used to implement the corresponding battery pack collision monitoring method in any of the above embodiments, and has the beneficial effects of the corresponding method embodiment, which will not be repeated here.

[0077] In some embodiments, Figure 6 A flowchart of another battery pack collision monitoring method provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the battery pack collision monitoring method is specifically as follows:

[0078] The signal detection system can be Figure 4 As shown, it is installed between the water-cooling plate and the bottom guard plate of the battery pack. During the driving process of the vehicle, the vehicle controller detects the reception status of the signal beams by each signal receiver through the signal detection system. If all the signal beams are received by the signal receiver, it means that the battery pack has not collided. When the battery pack collides, at least two signal beams will be blocked and not received by the signal receiver. When the signal beams emitted by some signal transmitters are not received by the signal receiver, it means that the optical path is blocked and the battery pack has collided. By detecting the number of the blocked signal beams, the collision position of the battery pack can be accurately determined. The controller simulates the collision position of the battery pack on the screen, allowing users to repair it in time to avoid more serious damage to the battery pack or even thermal runaway.

[0079] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied in a distributed scenario and performed by multiple devices working together. In such a distributed scenario, one of the multiple devices may only perform one or more steps of the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the method.

In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.
