[0001] The present application relates to the technical field of vehicles, in particular to a battery pack discarding method, a battery pack discarding system and a vehicle. BACKGROUND

[0002] With the rapid development of science and technology, more and more new energy vehicles appear in people's vision. As the main power source of vehicles, the battery is usually fixed on the chassis of the vehicle. Although the new energy vehicle has good energy-saving and emission-reducing effect, there is also a certain safety hazard. For example, when the new energy vehicle is in collision or other accidents, the battery box is easily deformed or the accessories are damaged, and then the battery is easily short-circuited, at this time, the large current will form heat burst and ignite the battery, causing a fire. At the same time, since the battery itself has an oxidizing agent, when the other positions of the vehicle are on fire, the battery is also easily ignited, which will further aggravate the fire situation. When the battery is ignited, it will pose a threat to the life safety of the people in the vehicle. At present, there is an urgent need for a method to improve the safety of the vehicle when the new energy vehicle is in collision. SUMMARY

[0013] Optionally, based on the collision warning signal, the battery pack landing time is determined, comprising:

[0014] in response to the collision warning signal, a landing distance is acquired, wherein the landing distance is a distance between the battery pack and the ground;

[0015] based on the landing distance, the battery pack landing time is determined.

[0016] Optionally, the method further comprises:

[0017] based on the collision warning signal, a light-on instruction is generated, wherein the light-on instruction is used to instruct the vehicle light of the current vehicle to light on according to a target condition.

[0020] the controller is used to:

[0021] based on the image information and the running information sent by the monitoring device, a collision state of the current vehicle is determined;

[0022] in response to the collision state being a preset collision state, a collision warning signal is generated, wherein the preset collision state is that the current vehicle collides with the to-be-approached object within a preset time and the collision level is greater than a target level;

[0023] based on the collision warning signal, a discarding instruction is generated and sent to the clamping device;

[0024] the clamping device is used to, in response to receiving the discarding instruction, change from a clamping state of clamping a battery pack to a releasing state of releasing the battery pack, so as to discard the battery pack.

[0025] Optionally, the system further comprises a protection device, the protection device being electrically connected with the controller;

These drawings and the written description are not intended to restrict the scope of the present application in any way, but to explain the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0054] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0055] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0056] In a first aspect, the embodiments of the present application provide a battery pack discarding method, which can be applied to a battery pack discarding system of a vehicle. The battery pack discarding system can include a controller, a monitoring device, a clamping device and the like. The controller is in an electrical connection state with each device and equipment in the battery pack discarding system, so that the controller and each device or equipment can realize mutual transmission of signals, data and instructions. It should be noted that the controller can be a vehicle controller of the vehicle, or a controller separately arranged for implementing the battery pack discarding method. The controller has functions of analyzing, processing, transmitting or storing the received data, signals or instructions. The battery pack discarding method provided by the embodiments of the present application can be executed by the controller.

[0057] In combination with Figure 1 As shown in the drawings, the battery pack discarding method provided by the embodiments of the present application includes steps 101 to 103.

[0058] In step 101, the controller determines a collision state of the current vehicle based on image information and running information of an object to be approached around the current vehicle.

[0059] It can be understood that, through step 101, whether the current vehicle will face a collision can be accurately predicted. It should be noted that the object to be approached can be an object such as another vehicle around the vehicle approaching the current vehicle. The image information is used to represent information such as the size, type, appearance, etc. of the object to be approached. The running information includes information such as the motion speed, motion trajectory, and distance between the object to be approached and the current vehicle, which is used to represent the running state of the object to be approached. Based on the image information and the running information, the controller can more accurately determine the collision state between the object to be approached and the current vehicle.

[0060] In step 102, the controller generates a collision warning signal in response to the collision state being a preset collision state.

[0061] The preset collision state is that the current vehicle collides with the object to be approached within a preset time and the collision level is greater than a target level. It should be noted that the preset collision state means that the current vehicle will collide with the object to be approached within a preset time period. The collision level is determined based on the danger level faced by the current vehicle after the object to be approached collides with the current vehicle, for example, in the preset collision state, the greater the speed of the object to be approached approaching the current vehicle, the higher the danger level and the greater the collision level. Alternatively, in the preset collision state, the larger the size of the object to be approached, the higher the danger level and the greater the collision level, for example, the collision level when the object to be approached is a large truck is greater than the collision level when the object to be approached is a bicycle. The above is only an example of different collision levels, and the determination conditions corresponding to different collision levels can be set by the technical personnel in the development process based on test data or real data.

[0062] In step 103, the controller generates a discard instruction based on the collision warning signal.

[0063] The discard instruction is used to instruct the clamping device to change from a clamping state of clamping the battery pack to a release state of releasing the battery pack, so as to discard the battery pack. It should be noted that the clamping device can be mounted on the vehicle body, and the clamping device has a driving assembly and a clamping assembly connected thereto. The driving assembly is used to control the clamping assembly to be in the clamping state or the release state. When the clamping device is in the clamping state, the clamping device is used to clamp the battery pack, so that the battery pack can be stably mounted on the vehicle body. When the clamping device is in the release state, the clamping device is separated from the battery pack, and at this time the battery pack is separated from the vehicle body to fall to the ground.

[0064] The battery pack discarding method provided in the embodiments of the present application can avoid executing the subsequent instruction of discarding the battery pack when the collision level is low, thereby ensuring the necessity of executing the operation of discarding the battery pack. In addition, when the vehicle is in collision, the battery pack can be discarded in time, so that the vehicle body is separated from the battery pack in time. In this way, the risk level can be further increased due to the rapid combustion and explosion of the battery pack when the vehicle is in collision, thereby improving the safety of the vehicle and the survival rate of the people in the vehicle.

[0065] The embodiments of the present application also provide a battery pack discarding method, which can be applied to a battery pack discarding system of a vehicle. The battery pack discarding system can include a controller, a monitoring device, a clamping device and the like. The controller is in electrical connection with each device and equipment in the battery pack discarding system, so that the controller and each device or equipment can transmit signals, data and instructions to each other. It should be noted that the controller can be a vehicle controller or a controller separately arranged for implementing the battery pack discarding method. The controller has the functions of analyzing, processing, transmitting or storing the received data, signals or instructions. The battery pack discarding method provided in the embodiments of the present application can be executed by the controller.

[0066] In combination with Figure 2 The battery pack discarding method provided in the embodiments of the present application includes steps 201 to 206.

[0067] In step 201, the controller determines the collision state of the current vehicle based on the image information and the running information of the object to be approached around the current vehicle.

[0068] It should be noted that the same as step 101, the step 201 will not be described herein.

[0069] In step 202, the controller generates a collision warning signal in response to the collision state being a preset collision state.

[0070] The preset collision state is that the current vehicle collides with the object to be approached within a preset time and the collision level is greater than a target level. It should be noted that the same as step 102, the step 202 will not be described herein.

[0071] In step 203, the controller generates a battery pack protection instruction based on the collision warning signal.

[0072] The battery pack protection instruction is used to instruct the protection device to protect the battery pack. It should be noted that the protection device is used to protect the battery pack, which can provide a certain buffering effect for the battery pack. When the battery pack falls to the ground, the protection device can reduce the collision force between the battery pack and the ground, thereby protecting the battery pack and reducing the damage degree and danger of the battery pack.

[0073] In some embodiments, the protection device is an airbag device, which includes an inflating device and an airbag. The inflating device is electrically connected with the controller, so that the controller and the inflating device can transmit signals or instructions to each other. When the airbag is in the inflated state, the airbag is between the ground and the side of the battery pack facing the ground. The controller controls the inflating assembly to inflate the airbag based on the collision warning signal, so that the airbag changes from the deflated state to the inflated state. Thus, when the battery pack falls to the ground, the airbag device can provide a certain buffering effect for the battery pack, thereby reducing the damage degree and danger of the battery pack. In some embodiments, when the battery pack includes a plurality of battery modules, the number of protection devices is also a plurality, and each protection device is located below the corresponding battery module to protect the battery module when it falls to the ground.

[0074] In some embodiments, the area of the airbag's projection on the ground is greater than the area of the battery pack's projection on the ground, so as to ensure that the airbag can protect the battery pack.

[0075] In step 204, the time when the battery pack falls to the ground is determined based on the collision warning signal.

[0076] In some embodiments, step 204 further includes obtaining a landing distance in response to the collision warning signal, wherein the landing distance is the distance between the battery pack and the ground. The time when the battery pack falls to the ground is determined based on the landing distance. Thus, the landing time point of the battery pack can be accurately determined.

[0077] In step 205, the controller generates a smoke release instruction based on the time when the battery pack falls to the ground.

[0078] The smoke release instruction is used to instruct the smoke generator to release smoke at the moment when the battery pack lands. It should be noted that the smoke generator is electrically connected with the controller, so that the controller and the smoke generator can transmit signals or instructions to each other. In some embodiments, the controller generates the smoke release instruction based on the moment when the battery pack lands. The smoke generator releases smoke in response to receiving the smoke release instruction, wherein the smoke can be non-toxic and harmless smoke with a special color, such as red smoke or yellow smoke. It can be understood that since the smoke is released at the moment when the battery pack lands, it can play a warning role, so as to prevent the discarded battery pack from causing secondary damage to surrounding people or other things. In addition, since the smoke is released at the moment when the battery pack lands, it can avoid the waste of smoke caused by early release of smoke and cannot play a warning effect, that is, it can ensure that the smoke can play a warning role.

[0079] In step 206, the controller generates a discarding instruction based on the collision warning signal.

[0080] The discarding instruction is used to instruct the clamping device to change from a clamping state of clamping the battery pack to a releasing state of releasing the battery pack, so as to discard the battery pack. It should be noted that step 206 is the same as step 103, so the embodiments of the present application will not be repeated. In some embodiments, the controller generates the discarding instruction and sends the discarding instruction to the clamping device at the same time. The clamping device changes from the clamping state to the releasing state in response to receiving the discarding instruction.

[0081] It should be noted that the number of clamping devices can be multiple. As shown in Figure 4 In some embodiments, each side of the battery pack 306 corresponds to at least one clamping device 303, so that when the clamping device 303 is in the clamping state, the battery pack can be clamped more stably. For example, when the battery pack 306 is substantially a cuboid, the four sides of the cuboid are respectively provided with one clamping device 303, and each clamping device 303 is used to clamp the part of the battery pack 306 on the side.

[0082] As shown in Figure 5As shown, in other embodiments, the battery pack 306 includes a plurality of battery modules 307, each of which corresponds to at least one clamping device 303. For example, each of the battery modules 307 is in the shape of a cuboid, and each of the battery modules 307 is provided with four clamping devices 303 on four sides, i.e., each of the battery modules 307 corresponds to four clamping devices 303. In this way, when the clamping devices 303 are released in response to receiving the discarding instruction, each of the battery modules 307 of the battery pack 306 can be released respectively. It should be understood that, after the battery pack 306 is divided into a plurality of battery modules 307, since the volume of each battery module 307 is small, the battery pack 306 cannot be misaligned with the vehicle due to the large volume, and it is ensured that each small volume battery module 307 can pass between two wheels, i.e., after the vehicle collides, the large volume battery pack 306 that falls to the ground can still be stopped at the bottom of the vehicle. Thus, it is ensured that the battery pack can be discarded when the vehicle is about to collide, and the vehicle is kept away from the battery pack that falls to the ground, improving the safety of personnel. It should be noted that, Figure 4 and Figure 5 The battery pack 306, the battery module 307, and the clamping device 303 shown are schematic diagrams, and the specific number and structure can be adjusted according to requirements.

[0083] In some embodiments, the battery pack discarding method further includes: generating a light-on instruction based on the collision warning signal by the controller, wherein the light-on instruction is used to instruct the vehicle lights to light up according to a target condition. It should be noted that the vehicle lights can be lights located outside the vehicle, so as to timely warn personnel or objects around the vehicle, so as to avoid secondary damage to the surrounding area caused by the battery pack after falling to the ground, and improve the safety of the surrounding area. It can also be a light located inside the vehicle, which can warn the personnel inside the vehicle, so that the personnel inside the vehicle can take measures quickly to reduce the degree of danger. It should be noted that the target condition includes one or more preset conditions of a preset color, a preset flashing frequency, and a preset flashing duration of the light. The preset color can be red, yellow, or multiple colors flashing alternately. The preset flashing frequency can be two times / 3 seconds, three times / 5 seconds, etc., which can be adjusted according to requirements. The preset flashing duration can be 30 minutes or 1 hour according to the preset flashing frequency, which can be adjusted according to requirements.

[0084] In some embodiments, the controller generates a slight collision prompt signal based on the current vehicle colliding with the object to be approached within a preset time and the collision level being not greater than the target level. The controller generates a light-on instruction based on the slight collision prompt signal, where the light-on instruction is used to instruct the vehicle light of the current vehicle to light up according to a target condition. It should be noted that the target condition includes one or more preset conditions of a preset color, a preset flashing frequency, and a preset flashing duration of the light. The preset color can be red, yellow, or multiple colors flashing alternately. The preset flashing frequency can be two times / 6 seconds, three times / 10 seconds, etc., which can be adjusted according to requirements. The preset flashing duration can be 10 minutes, 20 minutes, etc. according to the preset flashing frequency, which can be adjusted according to requirements. Thus, people or things around the current vehicle can be reminded to avoid secondary injury caused by collision.

[0085] In some embodiments, the battery pack discarding method further includes that the controller generates a voice instruction based on the collision warning signal, where the voice instruction is used to instruct the voice device of the current vehicle to play a target voice. For example, the target voice can be "Please note that the vehicle is about to collide seriously" and the like. Thus, the driver can be timely prompted about the dangerous situation of the current vehicle, so that the driver can take timely measures and carry out rescue, reduce the danger, further improve the safety of the vehicle and the people in the vehicle, and improve the survival rate of the people in the vehicle.

[0086] In some embodiments, the battery pack discarding method further includes that the controller generates a display prompt information instruction based on the collision warning signal, where the display prompt information instruction is used to instruct the center control screen of the current vehicle to display prompt information. For example, the prompt information can be "Please note that the vehicle is about to collide seriously" and the like. Thus, the driver can be timely prompted about the dangerous situation of the current vehicle, so that the driver can take timely measures, reduce the danger, further improve the safety of the vehicle and the people in the vehicle, and improve the survival rate of the people in the vehicle.

[0087] In some embodiments, the battery pack discarding method further includes that the controller generates a communication instruction based on the collision warning signal, where the communication instruction carries the position information of the current vehicle and is used to instruct the communication equipment of the current vehicle to contact relevant departments and send the position information to the relevant departments, such as the traffic control center and the like. Thus, the traffic control center can timely know the state of the current vehicle and take timely measures and carry out rescue to reduce the danger caused by collision.

[0088] In combination Figure 3As shown in the second aspect, based on the same technical concept as the battery pack discarding method provided in the embodiments of the present application, the embodiments of the present application also provide a battery pack discarding system. The system comprises a controller 301, a monitoring device 302 and a clamping device 303. The monitoring device 302 and the clamping device 303 are electrically connected to the controller 301 respectively.

[0089] The monitoring device 302 is used to monitor the image information and the running information of the object to be approached around the current vehicle. In some embodiments, the monitoring device 302 can comprise an image acquisition device and a radar. The image acquisition device can be, for example, a camera or other device with image acquisition functions such as photographing and video recording, to acquire the image information of the object to be approached around the current vehicle. The radar can be used to acquire the running information of the object to be approached around the current vehicle, such as the motion speed, the motion trajectory, and the distance between the object to be approached and the current vehicle. In some embodiments, the monitoring device 302 has image acquisition functions and running state monitoring functions to acquire the image information and the running information of the object to be approached around the current vehicle. For example, the monitoring device 302 can be a vision sensor.

[0090] The controller 301 is used to: determine the collision state of the current vehicle based on the image information and the running information sent by the monitoring device 302; generate a collision warning signal in response to the collision state being a preset collision state, wherein the preset collision state is that the current vehicle collides with the object to be approached within a preset time and the collision level is greater than a target level; generate a discarding instruction based on the collision warning signal, and send the discarding instruction to the clamping device 303.

[0091] The clamping device 303 is used to respond to the discarding instruction received, and change from the clamping state of clamping the battery pack to the release state of releasing the battery pack, to discard the battery pack.

[0092] In some embodiments, the controller 301 is further used to: start the monitoring device 302 in response to a start trigger operation. It should be noted that the start trigger operation can be a trigger operation allowed by the user to start the monitoring device 302. For example, the central control screen of the vehicle displays a start control corresponding to the monitoring device 302, and the controller 301 starts the monitoring device 302 in response to the user's click, long press or other trigger operation on the start control. The process of starting the monitoring device 302 needs to be re-executed every time the user uses the vehicle. It should be understood that when the monitoring device 302 is started, the monitoring device 302 can be used to acquire the image information and the running information of the object to be approached around the vehicle in real time or according to a preset time interval. Then, the controller 301 can execute the above process of discarding the battery pack based on the image information and the running information.

[0093] In some embodiments, the system further comprises a protection device 304 electrically connected between the controller 301. The controller 301 is further configured to generate a protection instruction based on the collision warning signal, and send the protection instruction to the protection device 304. The protection device 304 is configured to protect the battery pack in response to receiving the protection instruction. It can be understood that the protection device 304 can protect the battery pack, so as to buffer the battery pack when the battery pack falls to the ground.

[0094] In some embodiments, the system further comprises a smoke generator electrically connected between the controller 301. The controller 301 is further configured to determine a battery pack falling time based on the collision warning signal, generate a smoke release instruction based on the battery pack falling time, and send the smoke release instruction to the smoke generator. The smoke generator is configured to release smoke at the battery pack falling time in response to receiving the smoke release instruction. It can be understood that the smoke generator can alert people or things around the battery pack, avoiding secondary injury caused by the danger of the battery pack.

[0095] In some embodiments, the system further comprises a vehicle light 305 electrically connected between the controller 301. The controller 301 is further configured to generate a light-on instruction based on the collision signal, and send the light-on instruction to the vehicle light 305. The vehicle light 305 is configured to turn on the light according to the target condition in response to receiving the light-on instruction. It can be understood that the light-on form can alert people or things around the current vehicle, avoiding secondary injury caused by the danger of the battery pack.

[0096] It should be noted that the functions and effects of each component in the battery pack discarding system provided by the embodiments of the present application are the same as those of the corresponding components in the battery pack discarding method provided by the embodiments of the present application. Therefore, the embodiments of the present application will not be described here.
