Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a battery failure processing method, device, electronic equipment and storage medium. Background Art

[0002] New energy vehicles (such as electric vehicles, plug-in hybrid vehicles and extended-range electric vehicles, etc.) usually use different types of batteries to provide power. Commonly used battery types include lithium iron phosphate batteries and ternary lithium batteries. Different battery types have their own advantages and disadvantages based on energy density, safety, cost and application scenarios. For example, lithium iron phosphate batteries are safer, lower in cost and have a longer service life, but have lower energy density and poor low-temperature performance. Ternary lithium batteries have very high energy density, can provide a longer driving range, and have relatively good low-temperature performance, but have higher costs and lower safety.

[0003] Lithium iron phosphate batteries are safer in the event of battery failures (such as spontaneous combustion, punctures, and bumps), have better thermal stability, and have a relatively low risk of spontaneous combustion, but ternary lithium batteries are more likely to have internal short circuits under bumps or external impacts, causing the battery temperature to rise sharply, causing spontaneous combustion or explosion. Regardless of whether new energy vehicles use lithium iron phosphate batteries or ternary lithium batteries, when accidents such as battery spontaneous combustion occur, the vehicle is often completely burned, causing serious damage to the lives and property of the driver and passengers.

[0046] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0047] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes, and are not used to limit the scope of these messages or information.

[0048] like Figure 1 As shown, a battery failure processing method provided by an embodiment of the present invention is applied to a battery pack of a vehicle, wherein the battery pack includes a plurality of battery module packs, and the plurality of battery module packs are arranged in different spaces on the vehicle, and each of the spaces is provided with a mechanical component for fixing the battery module pack and an interface for charging and discharging the battery module pack, and the battery failure processing method includes:

[0049] S100: monitoring the status of the plurality of battery module packs, and when any of the battery module packs is in a faulty state, sending the fault information of the corresponding battery module pack to a terminal device.

[0050] Specifically, when the vehicle is in the starting state, the status of multiple battery module packs is monitored through the battery management system (user authorization in advance is required). After the battery module pack fails, the battery management system can detect the fault information of the battery module pack and then send the fault information to the terminal device, such as user terminal devices (mobile phones, etc.) and vehicle-mounted terminal devices.

[0051] S200: disconnecting the mechanical component, the interface and the battery module pack in the fault state according to a corresponding separation control method according to the level of the fault state, so as to separate the battery module pack in the fault state from the vehicle.

[0052] Specifically, the battery pack includes a plurality of battery module packs, each of which is arranged in a different space and fixed by corresponding mechanical components, and each battery module pack has a corresponding charging and discharging interface. According to the level of the fault state, the connection between the mechanical components and the interface and the battery module pack in the fault state can be disconnected according to the corresponding separation control method. For example, when the fault state is level one (battery temperature is too high, etc.), when a separation instruction is received from the terminal device, the battery module pack in the fault state begins to separate from the vehicle, and the corresponding mechanical component is disconnected from the battery module pack in the fault state, and the corresponding interface for charging and discharging is also disconnected from the battery module pack in the fault state, thereby separating the battery module pack in the fault state from the vehicle, without the need to separate the battery pack of the vehicle as a whole from the vehicle. For example, when the fault state is level two (battery spontaneous combustion, etc.), the vehicle control system automatically generates a separation instruction to disconnect the mechanical components and the interface from the battery module pack in the fault state, thereby preventing more serious losses due to untimely user response, and effectively ensuring the safety of the vehicle and personnel.

[0053] S300: According to the level of the fault state, the vehicle is controlled to move away from the separation position of the battery module pack in accordance with a corresponding movement control method.

[0054] Specifically, since only the battery module pack in a faulty state is separated from the vehicle, the remaining battery module packs can still support the vehicle to continue driving. According to the level of the fault state, the vehicle is controlled to drive away from the separation position of the battery module pack according to the corresponding mobile control method. For example, when the fault state is level one, the user can send a mobile command to the vehicle control system through the terminal device, and the vehicle control system controls the vehicle to drive away from the separation position of the battery module pack, thereby ensuring the safety of the vehicle. For example, when the fault state is level two, the vehicle control system automatically generates a mobile command to control the vehicle to drive away from the separation position of the battery module pack, thereby preventing more serious losses due to untimely user response, and effectively ensuring the safety of the vehicle and personnel.

[0055] In this embodiment, by monitoring the status of multiple battery module packs, when any battery module pack is in a faulty state, the fault information of the corresponding battery module pack is sent to the terminal device, and the user can issue a separation command through the terminal device, or the vehicle control system can automatically generate a separation command to disconnect the mechanical components and interfaces from the battery module pack in the faulty state, thereby separating the battery module pack in the faulty state from the vehicle, which can avoid overall damage to the battery pack and reduce environmental pollution. There is no need to separate the battery pack of the vehicle from the vehicle as a whole, and the remaining battery module packs can still support the vehicle to continue driving. The user can open the door in time to escape, and can also send a movement command to the vehicle control system through the terminal device, or after the vehicle control system automatically generates a movement command, the vehicle control system controls the vehicle to drive away from the separation position of the battery module pack, thereby ensuring vehicle safety.

[0056] Optionally, the terminal device includes a user terminal device; when any of the battery module packs is in a fault state, sending the fault information of the corresponding battery module pack to the terminal device includes:

[0057] S110: Acquire fault information of the battery module pack in a fault state through a battery management system.

[0058] Specifically, combined Figure 2 As shown, the battery management system is used to monitor the status of multiple battery module packs. The battery management system can obtain fault information of battery module packs in a faulty state, wherein the fault state includes puncture of the battery module pack, excessive temperature for a long time, spontaneous combustion, collision, etc.

[0059] S120: Transmit the fault information from the battery management system to the power domain controller, and confirm the fault information through the power domain controller.

[0060] Specifically, combined Figure 2 and Figure 5 As shown, when the battery management system detects the above fault state, it transmits the corresponding fault information to the power domain controller, and the power domain controller confirms the fault information.

[0061] S130: Transmitting the fault information from the power domain controller to the user terminal device via the vehicle-mounted wireless terminal, so as to display a warning interface corresponding to the fault information on the user terminal device.

[0062] Specifically, combined Figure 2 and Figure 5As shown, after the power domain controller (or power domain controller) confirms the fault information, it transmits the fault information to the vehicle-mounted wireless terminal through the gateway, and the vehicle-mounted wireless terminal finally transmits the fault information to the user terminal device. The user can view the warning interface corresponding to the fault information through the user terminal device, and choose whether to discard the battery module package according to the options provided on the warning interface.

[0063] In this optional embodiment, fault information of a battery module pack in a faulty state is obtained through a battery management system, and the corresponding fault information is transmitted to a power domain controller, which confirms the fault information and then transmits the fault information from the power domain controller to a user terminal device through an on-board wireless terminal. The user can view a warning interface corresponding to the fault information through the user terminal device, and choose whether to discard the battery module pack according to the options provided on the warning interface, thereby promptly separating the battery module pack in a faulty state from the vehicle.

[0064] Optionally, the transmitting the fault information from the power domain controller to the user terminal device through the vehicle-mounted wireless terminal includes:

[0065] The fault information is sent to the cloud through the vehicle-mounted wireless terminal, so as to send the fault information to the user terminal device through the cloud, wherein the cloud includes the Internet of Vehicles cloud or the APP background.

[0066] Specifically, the vehicle-mounted wireless terminal transmits the fault information to the cloud (e.g., the Internet of Vehicles cloud or APP background), and the cloud sends the fault information to the user terminal device, so that the user can view the warning interface corresponding to the fault information on the user terminal device and choose whether to discard the battery module package according to the options provided on the warning interface.

[0067] In this optional embodiment, the transmission of fault information is achieved through an interactive protocol between the cloud and the user terminal device, ensuring that the user can receive the fault information in a timely manner and perform corresponding processing, and the battery module package in a faulty state can be separated from the vehicle in a timely manner.

[0068] Optionally, the terminal device includes a vehicle-mounted terminal device; when any of the battery module packs is in a fault state, sending the fault information of the corresponding battery module pack to the terminal device further includes:

[0069] After the fault information is confirmed by the power domain controller, the fault information is sent to the vehicle-mounted terminal device, and the vehicle-mounted terminal device is controlled to display a warning interface corresponding to the fault information.

[0070] Specifically, combined Figure 5As shown, after the power domain controller (or power domain controller) confirms the fault information, it transmits the fault information to the vehicle terminal device (including the vehicle display screen and multimedia equipment, etc.) through the gateway, so that the user can view the warning interface corresponding to the fault information on the vehicle terminal device, and choose whether to discard the battery module package according to the options provided on the warning interface.

[0071] In this optional embodiment, by transmitting the fault information to the vehicle-mounted terminal device, the user can view the warning interface corresponding to the fault information on the vehicle-mounted terminal device, and choose whether to discard the battery module pack according to the options provided on the warning interface, thereby promptly separating the battery module pack in a faulty state from the vehicle.

[0072] Optionally, disconnecting the connection between the mechanical component, the interface and the battery module pack in the fault state in a corresponding separation control manner according to the level of the fault state includes:

[0073] S210: When the fault state is level one, disconnecting the mechanical component, the interface and the battery module pack in the fault state according to a separation instruction received from the terminal device;

[0074] Specifically, combined Figure 3 As shown, the fault status is divided into different levels. For example, if the temperature is too high or other lower-level faults (i.e., the fault status is level one), the user may be requested to determine whether to separate the battery module pack. The battery module pack may be separated after obtaining the user's consent.

[0075] S220: When the fault state is level 2, a separation instruction is generated to disconnect the mechanical component, the interface and the battery module pack in the fault state; wherein the urgency of the fault state when level 1 is lower than the urgency of the fault state when level 2 is.

[0076] Specifically, combined Figure 3 As shown, for a battery module pack that is in a serious fault state such as spontaneous combustion (i.e., the fault state is level 2), the vehicle control system can directly disconnect the mechanical components and interfaces from the battery module pack in the fault state without the user's consent, thereby separating the battery module pack in the fault state from the vehicle, without the need to separate the entire battery pack from the vehicle.

[0077] In this optional embodiment, different separation control methods are determined according to the levels of different fault states to disconnect the mechanical components, interfaces and battery module packs in a preset fault state, thereby preventing more serious losses due to untimely user response and effectively ensuring the safety of vehicles and personnel.

[0078] Optionally, controlling the vehicle to drive away from the separation position of the battery module pack in a corresponding movement control manner according to the level of the fault state includes:

[0079] S310: When the fault state is level one, the moving instruction sent by the user terminal device is received from the cloud through the vehicle-mounted wireless terminal.

[0080] Specifically, combined Figure 4 and Figure 5 As shown, when the fault status is level one, the user can issue a mobile command through the user terminal device, which is transmitted to the vehicle-mounted wireless terminal via the cloud.

[0081] S320: When the fault state is level 2, generating a movement instruction, wherein the urgency of the fault state when level 1 is lower than the urgency of the fault state when level 2 is.

[0082] Specifically, when the fault status is level 2, the vehicle control system automatically generates movement instructions to control the vehicle to move away from the separation position of the battery module package, preventing more serious losses due to untimely user response, and effectively ensuring the safety of the vehicle and personnel.

[0083] S330: Send the movement instruction to the intelligent driving controller, the power domain controller and the body domain controller to control the vehicle to perform a movement operation corresponding to the movement instruction to drive away from the separation position of the battery module package.

[0084] Specifically, combined Figure 4 and Figure 5 As shown, the on-board wireless terminal sends the movement command to the intelligent driving controller (or intelligent driving domain controller), the power domain controller (or power domain controller) and the body domain controller (or body domain controller). The intelligent driving controller, the power domain controller and the body domain controller can realize the movement operation of the vehicle (such as moving forward, backward, leaving a parking space, turning, etc.), or realize the above operations according to the movement command automatically generated by the vehicle control system, so as to drive the vehicle away from the separation position of the battery module package to avoid damage to the vehicle caused by spontaneous combustion of the battery module package.

[0085] In this optional embodiment, the intelligent driving controller, the power domain controller and the body domain controller are controlled according to the movement instructions issued by the user through the user terminal device or the movement instructions automatically generated by the vehicle control system, and the vehicle is controlled to perform the movement operation corresponding to the movement instruction, thereby driving the vehicle away from the separation position of the battery module pack to avoid damage to the vehicle due to spontaneous combustion of the battery module pack.

[0086] Optionally, the battery failure processing method further includes:

[0087] When a separation instruction is received from the terminal device, if the battery module pack in a faulty state is not separated from the vehicle, a rescue reminder is transmitted to the terminal device.

[0088] Specifically, when the vehicle control system receives a separation command from the terminal device, it controls the battery module pack in a faulty state to separate from the vehicle through the battery management system. If the separation fails to occur normally, a rescue reminder is transmitted to the terminal device. For example, the user is prompted on the user terminal device (the same applies to the vehicle-mounted terminal device) whether to call for emergency rescue. If the user chooses yes, the user terminal device will make a call for emergency rescue. If the user chooses no, the user terminal device will prompt the user to manually trigger the discarding of the battery module pack. If the user chooses not to manually trigger the discarding of the battery module pack, the user can be prompted on the user terminal device of the expected loss.

[0089] In this optional embodiment, after the battery module package in a faulty state fails to separate, a rescue reminder is transmitted to the terminal device, and the user can call an emergency rescue number through the user terminal device, so that the battery module package in the faulty state can be processed in time, thereby improving vehicle safety.
