[0002] With the popularity of new energy vehicles, the requirements for automobile safety are getting higher and higher, and the application of explosive fuses (Pyrofuse) in battery systems has become particularly important. In new energy vehicles, Pyrofuse mainly protects the battery pack from damage caused by accidents such as short circuits, overcurrent, and collisions. When a vehicle collides, Pyrofuse can cut off the electrical connection between the battery and other parts of the vehicle in a very short time, thereby effectively avoiding fires or secondary disasters.

[0003] In the related art, when a vehicle collides, an explosive fuse will be immediately detonated to prevent a short circuit from causing a fire. However, the explosive fuse is a disposable device. Once it is detonated, the vehicle needs to be unpacked for repair or replacement regardless of the degree of damage. The vehicle repair cost is high and the repair cycle is long.

[0025] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0027] In conjunction with the accompanying drawings, the explosion fuse control method, device, equipment, medium, product and vehicle provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0028] Figure 1 Schematic diagram of the flow of the explosion fuse control method provided in the embodiment of the present application. Figure 1 As shown, the explosion fuse control method may include:

[0029] Step 101: When a vehicle collides and the airbag is deployed, obtain the vehicle speed at the time of the collision;

[0030] The embodiments of the present application do not limit the method used to detect whether a vehicle collision occurs, and any available method can be applied to the embodiments of the present application.

[0031] In some possible implementations of the embodiments of the present application, when a vehicle collides, an airbag controller (Airbag Control Unit) will decide whether to detonate the airbag. When the airbag is not detonated, it means that the collision is minor and will not cause a fire. At this time, there is no need to detonate the explosion fuse. When the airbag is detonated, the airbag controller sends an airbag detonation signal to the battery management system (Battery management system, BMS). After receiving the airbag detonation signal, the battery management system needs to determine whether to detonate the explosion fuse based on the vehicle speed when the collision occurs.

[0032] In some possible implementations of the embodiments of the present application, the vehicle speed may be acquired through the vehicle electronic stability control system (ESC).

[0033] Step 102: Control the explosion fuse of the vehicle according to the vehicle speed.

[0034] In some possible implementations of the embodiments of the present application, step 102 may include: when the vehicle speed is greater than or equal to a vehicle speed threshold, detonating an explosion fuse.

[0035] In some possible implementations of the embodiments of the present application, the vehicle speed threshold in the embodiments of the present application can be obtained by testing and calibrating the vehicle.

[0036] When a collision occurs, if the vehicle speed is greater than or equal to the speed threshold, there is a high probability that a fire will occur in the vehicle, and the explosion fuse will be directly ignited.

[0037] In some possible implementations of the embodiments of the present application, step 102 may include: when the vehicle speed is less than a vehicle speed threshold but the current in the battery pack of the vehicle (Pack current) is greater than or equal to a current threshold, detonating an explosion fuse.

[0038] In some possible implementations of the embodiments of the present application, the current threshold in the embodiments of the present application can be obtained by testing and calibrating the battery pack of the vehicle.

[0039] In some possible implementations of the embodiments of the present application, a shunt may be used to measure the Pack current of the vehicle.

[0040] When a collision occurs, when the vehicle's Pack current is greater than or equal to the current threshold, the current in the vehicle's battery pack is large. At this time, the probability of a vehicle fire is high, and the explosion fuse will be ignited.

[0041] In the embodiment of the present application, when a vehicle collides and the airbag is detonated, the vehicle speed at the time of the collision is obtained; and the vehicle explosion fuse is controlled according to the vehicle speed. In this way, the explosion fuse is not detonated immediately when the vehicle collides, which can reduce unnecessary detonation of the explosion fuse, save costs and troubleshooting time, and reduce vehicle maintenance costs and maintenance cycles.

[0042] In some possible implementations of the embodiments of the present application, when the vehicle speed is less than a vehicle speed threshold, before detonating the explosion fuse, the explosion fuse control method provided by the embodiments of the present application may also include: disconnecting the relay of the vehicle's high-voltage system; determining whether the relay disconnection is successful; accordingly, in the event that the relay disconnection fails, detonating the explosion fuse.

[0043] In some possible implementations of the embodiments of the present application, the relays of the high-voltage system of the vehicle in the embodiments of the present application include but are not limited to: a main relay on the positive side of the high-voltage system of the vehicle and / or a main relay on the negative side of the high-voltage system of the vehicle, wherein the main relay on the positive side of the high-voltage system of the vehicle can be referred to as a main positive relay, and the main relay on the negative side of the high-voltage system of the vehicle can be referred to as a main negative relay.

[0044] The embodiment of the present application does not limit the method used to determine whether the relay disconnection is successful, and any available method can be applied to the embodiment of the present application. For example, whether the relay disconnection is successful is determined based on whether the vehicle's Pack current is greater than the current threshold. When the vehicle's Pack current is greater than the current threshold, it is determined that the relay disconnection failed. When the vehicle's Pack current is less than or equal to the current threshold, it is determined that the relay disconnection is successful.

[0045] When the vehicle speed is less than the speed threshold when a collision occurs, the relay of the vehicle's high-voltage system is first controlled to disconnect. If the relay of the vehicle's high-voltage system is successfully disconnected, there is no need to detonate the explosive fuse. When the relay of the vehicle's high-voltage system fails to disconnect, if the vehicle's Pack current is less than the current threshold, there is no need to detonate the explosive fuse. If the vehicle's Pack current is greater than or equal to the current threshold, the explosive fuse is detonated.

[0046] In the embodiment of the present application, when a vehicle collides and the airbag is detonated, if the vehicle speed is low, the relay of the high-voltage system of the vehicle is disconnected first, and when the relay of the high-voltage system of the vehicle fails to disconnect, if the pack current of the vehicle is large, the explosion fuse is detonated. By disconnecting the relay of the high-voltage system of the vehicle first, the upgrade cost can be saved.

[0047] In some possible implementations of the embodiments of the present application, the vehicle's Pack current can be used to determine whether the relay disconnection is successful, and can also be used to determine whether the explosion fuse needs to be ignited, thereby eliminating the need to use other methods to determine whether the relay disconnection is successful, thereby saving resources occupied by other methods to determine whether the relay disconnection is successful.

[0048] In some possible implementations of the embodiments of the present application, the explosion fuse control method provided in the embodiments of the present application may further include: when the relay is disconnected successfully and there is a risk of thermal runaway of the battery pack, detonating the explosion fuse.

[0049] The embodiments of the present application do not limit the method used to detect whether the battery pack has a risk of thermal runaway, and any available method can be applied to the embodiments of the present application. For example, the expansion of the battery pack volume is detected by a volume expansion detection method to determine whether the battery pack has a risk of thermal runaway. For another example, the pressure change inside the battery pack is detected by a pressure detection method to determine whether the battery pack has a risk of thermal runaway. For another example, the temperature inside the battery pack is detected by a temperature detection method to determine whether the battery pack has a risk of thermal runaway.

[0050] When the relay is disconnected successfully but the battery pack is at risk of thermal runaway, the possibility of fire is relatively high and the explosion fuse needs to be ignited.

[0051] In the embodiment of the present application, when the relay is disconnected successfully but there is a risk of thermal runaway in the battery pack, the explosion fuse is ignited to reduce the probability of fire.

[0052] In some possible implementations of the embodiments of the present application, the explosion fuse control method provided by the embodiments of the present application may further include: latching a vehicle collision fault.

[0053] In the embodiment of the present application, by latching the vehicle collision fault, the high-voltage system in the vehicle can be prohibited from being high-voltage again to avoid fire. After the vehicle maintenance personnel handle the vehicle collision fault, they unlock the vehicle collision fault and then turn on the high-voltage system of the vehicle.

[0054] Figure 2 is a connection diagram of various devices provided in the embodiments of the present application; Figure 3 It is a schematic diagram of the process of controlling an explosion fuse provided in an embodiment of the present application.

[0065] Step 309 : Check whether the battery pack has a risk of thermal runaway. If yes, execute step 303 ; if no, execute step 304 .

[0066] When the vehicle collides, if the airbag controller 201 explodes the airbag, the airbag controller 201 sends an airbag explosion signal to the battery management system 202; after receiving the airbag explosion signal, the battery management system 202 obtains the vehicle speed when the vehicle collides through the electronic stability control system 203, and after obtaining the vehicle speed, compares the vehicle speed with the vehicle speed threshold, and directly explodes the explosion fuse 207 if the vehicle speed is greater than or equal to the vehicle speed threshold; if the vehicle speed is less than the vehicle speed threshold, disconnect the main positive relay 204 and the main negative relay 205, and when both the main positive relay 204 and the main negative relay 205 fail, obtain the Pack current through the shunt 206, and if the Pack current is greater than or equal to the current threshold, explode the explosion fuse. After the main positive relay 204 and the main negative relay 205 are disconnected or the explosion fuse is exploded, the vehicle collision fault is latched.

In this way, the explosion fuse is not detonated immediately when the vehicle collides, which can reduce unnecessary detonation of the explosion fuse, save costs and troubleshooting time, and reduce vehicle maintenance costs and maintenance cycles.

[0073] In some possible implementations of the embodiments of the present application, the control module 402 is specifically used to:

[0074] When the vehicle speed is less than the vehicle speed threshold but the current in the battery pack of the vehicle is greater than or equal to the current threshold, the explosion fuse is ignited.

[0076] A disconnect module, a relay for disconnecting the vehicle's high voltage system;

[0077] A judgment module is used to judge whether the relay disconnection is successful;

[0078] The control module 402 is specifically used for:

[0079] In the event that the relay fails to open, the explosion fuse is blown.

[0080] In the embodiment of the present application, when a vehicle collides and the airbag is detonated, if the vehicle speed is low, the relay of the high-voltage system of the vehicle is disconnected first, and when the relay of the high-voltage system of the vehicle fails to disconnect, if the pack current of the vehicle is large, the explosion fuse is detonated.
