Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a battery fault handling method, apparatus, electronic device, and storage medium. Background Technology

[0002] New energy vehicles (such as electric vehicles, plug-in hybrid electric vehicles, and range-extended electric vehicles) typically 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, cheaper, and have a longer lifespan, but have lower energy density and poorer low-temperature performance. Ternary lithium batteries, on the other hand, have very high energy density, can provide a longer driving range, and have relatively better low-temperature performance, but have higher cost and lower safety.

[0003] Lithium iron phosphate (LFP) batteries are safer in the event of battery malfunctions (such as spontaneous combustion, puncture, and impact), exhibit better thermal stability, and have a relatively lower risk of spontaneous combustion. However, ternary lithium batteries are more prone to internal short circuits under impact or external shocks, leading to a rapid increase in battery temperature and potentially causing spontaneous combustion or explosion. Regardless of whether new energy vehicles use LFP or ternary lithium batteries, in the event of battery spontaneous combustion or other accidents, the vehicle is often completely destroyed, potentially resulting in serious loss of life and property for the driver and passengers. Summary of the Invention

[0007] The status of multiple battery module packs is monitored, and when any battery module pack is in a fault state, the fault information of the corresponding battery module pack is sent to the terminal device.

[0008] According to the level of the fault state, the connection between the mechanical component, the interface and the battery module pack in the fault state is disconnected according to the corresponding separation control method, so as to separate the battery module pack in the fault state from the vehicle.

[0019] When the fault state is Level 1, the mechanical component, the interface and the battery module pack in the fault state are disconnected according to the separation command received from the terminal device;

[0020] When the fault state is level two, a separation command 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 is level one is lower than the urgency of the fault state is level two.

[0021] Optionally, controlling the vehicle to move away from the separation position of the battery module pack according to the level of the fault state and the corresponding movement control method includes:

[0022] When the fault status is Level 1, the vehicle-mounted wireless terminal receives the movement command sent by the user terminal device from the cloud.

[0023] When the fault status is level two, a movement command is generated, wherein the urgency of the fault status is level one, which is lower than the urgency of the fault status is level two.

[0024] The movement command is sent to the intelligent driving controller, the power domain controller, and the body domain controller to control the vehicle to perform the movement operation corresponding to the movement command, so as to drive away from the separation position of the battery module pack.

[0025] Optionally, the battery fault handling method further includes:

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

[0048] like Figure 1 As shown in the figure, an embodiment of the present invention provides a battery fault handling method applied to a vehicle battery pack. The battery pack includes multiple battery module packs arranged in different spaces on the vehicle. Each space is provided with mechanical components for fixing the battery module packs and interfaces for charging and discharging the battery module packs. The battery fault handling method includes:

[0049] S100: Monitor the status of multiple battery module packs, and when any battery module pack is in a fault state, send the corresponding fault information of the battery module pack to the terminal device.

[0050] Specifically, when the vehicle is running, the battery management system monitors the status of multiple battery module packs (user authorization is required in advance). If a battery module pack fails, the battery management system can detect the fault information and then send the fault information to terminal devices, such as user terminal devices (mobile phones, etc.) and vehicle terminal devices.

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

[0052] Specifically, the battery pack includes multiple battery module packs, each arranged in a different space and fixed by corresponding mechanical components. Each battery module pack has a corresponding charging and discharging interface. Depending on the level of the fault, the mechanical components and interfaces can be disconnected from the faulty battery module pack according to the corresponding separation control method. For example, when the fault is level one (such as overheating of the battery), upon receiving a separation command from the terminal device, the faulty battery module pack begins to separate from the vehicle. The corresponding mechanical components disconnect from the faulty battery module pack, and the corresponding charging and discharging interfaces also disconnect from the faulty battery module pack, thus separating the faulty battery module pack from the vehicle without having to separate the entire vehicle's battery pack from the vehicle. For example, when the fault is level two (such as spontaneous combustion of the battery), the vehicle control system automatically generates a separation command to disconnect the mechanical components and interfaces from the faulty battery module pack, preventing more serious losses due to untimely user response and effectively ensuring the safety of the vehicle and personnel.

[0053] S300: Based on the level of the fault state, control the vehicle to move away from the separation position of the battery module pack according to the corresponding movement control method.

[0054] Specifically, since only the battery modules in a faulty state are separated from the vehicle's battery pack, the remaining battery modules can still support the vehicle's continued operation. Based on the fault level, the vehicle is controlled to move away from the separated battery modules using the corresponding movement control method. For example, in a level one fault, the user can send a movement command to the vehicle control system via a terminal device. The vehicle control system then controls the vehicle to move away from the separated battery modules, thus ensuring vehicle safety. Conversely, in a level two fault, the vehicle control system automatically generates a movement command to control the vehicle to move away from the separated battery modules, preventing more serious losses due to delayed user response and effectively ensuring the safety of the vehicle and its occupants.

[0055] In this embodiment, by monitoring the status of multiple battery module packs, when any battery module pack is in a fault state, the corresponding fault information of the battery module pack is sent to the terminal device. 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 faulty battery module pack, thereby separating the faulty battery module pack from the vehicle. This avoids overall damage to the battery pack, reduces environmental pollution, and eliminates the need to completely separate the vehicle's battery pack from the vehicle. The remaining battery module packs can still support the vehicle's continued operation, allowing the user to open the car door and escape in time. The user 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 can control the vehicle to move away from the separation position of the battery module pack, thereby ensuring vehicle safety.

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

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

[0058] Specifically, in combination 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. Fault states include puncture, excessively high temperature for a long period of time, spontaneous combustion, and collision.

[0059] S120: The fault information is transmitted from the battery management system to the power domain controller, and the fault information is confirmed by the power domain controller.

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

[0061] S130: The fault information is transmitted 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, in combination 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 wireless terminal through the gateway. The vehicle wireless terminal then 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 pack according to the options provided on the warning interface.

[0063] In this optional embodiment, the battery management system obtains the fault information of the battery module pack in a faulty state, transmits the corresponding fault information to the power domain controller, the power domain controller confirms the fault information, and then transmits the fault information from the power domain controller to the user terminal device through the vehicle wireless terminal. 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 pack according to the options provided by the warning interface, so as to promptly separate the battery module pack in a faulty state from the vehicle.

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

[0065] The fault information is sent to the cloud via the vehicle-mounted wireless terminal, and then sent to the user terminal device via the cloud, wherein the cloud includes a vehicle network cloud or an APP backend.

[0066] Specifically, the vehicle-mounted wireless terminal transmits fault information to the cloud (such as the vehicle network cloud or the APP backend), and the cloud sends the fault information to the user terminal device. The user can then view the warning interface corresponding to the fault information on the user terminal device and choose whether to discard the battery module pack based on the options provided on the warning interface.

[0067] In this optional embodiment, fault information is transmitted through the interaction protocol between the cloud and the user terminal device, ensuring that the user can receive the fault information in a timely manner and take corresponding actions, and promptly detach the battery module pack in a faulty state from the vehicle.

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

[0069] After the power domain controller confirms the fault information, it sends the fault information to the vehicle terminal device and controls the vehicle terminal device to display a warning interface corresponding to the fault information.

[0070] Specifically, in combination 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 equipment (including the vehicle display screen and multimedia equipment, etc.) through the gateway. The user can then view the warning interface corresponding to the fault information on the vehicle terminal equipment and choose whether to discard the battery module pack based on the options provided on the warning interface.

[0071] In this optional embodiment, by transmitting fault information to the vehicle terminal device, 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 pack according to the options provided on the warning interface, so as to promptly separate the battery module pack in a faulty state from the vehicle.

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

[0073] S210: When the fault state is Level 1, disconnect the mechanical component, the interface and the battery module pack in the fault state according to the separation command received from the terminal device;

[0074] Specifically, in combination 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 can be asked whether to separate the battery module pack. After obtaining the user's consent, the battery module pack can be separated.

[0075] S220: When the fault state is level two, a separation command 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 is level one is lower than the urgency of the fault state is level two.

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

[0077] In this optional embodiment, different separation control methods are determined according to the level of different fault states to disconnect the mechanical components, interfaces and battery module packs in preset fault states, so as to prevent more serious losses due to untimely user response and effectively ensure the safety of vehicles and personnel.

[0078] Optionally, controlling the vehicle to move away from the separation position of the battery module pack according to the level of the fault state and the corresponding movement control method includes:

[0079] S310: When the fault status is Level 1, the vehicle-mounted wireless terminal receives the movement command sent by the user terminal device from the cloud.

[0080] Specifically, in combination Figure 4 and Figure 5 As shown, when the fault status is Level 1, the user can issue a movement command through the user terminal device, which is transmitted to the vehicle wireless terminal via the cloud.

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

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

[0083] S330: The movement command is sent to the intelligent driving controller, the power domain controller, and the body domain controller to control the vehicle to perform the movement operation corresponding to the movement command, so as to drive away from the separation position of the battery module pack.

[0084] Specifically, in combination Figure 4 and Figure 5 As shown, the vehicle-mounted wireless terminal sends movement commands 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). Through the intelligent driving controller, the power domain controller, and the body domain controller, the vehicle's movement operations (such as moving forward, backward, leaving a parking space, turning, etc.) can be realized, or the above operations can be realized according to the movement commands automatically generated by the vehicle control system, thereby driving the vehicle away from the separation position of the battery module pack and avoiding damage to the vehicle caused by spontaneous combustion of the battery module pack.

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

[0086] Optionally, the battery fault handling method further includes:

[0087] When a separation command is received from the terminal device, if the battery module pack in a faulty state has not been separated from the vehicle, a rescue reminder will be 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 separation fails, a rescue reminder is transmitted to the terminal device. For example, the user terminal device (and the vehicle terminal device) prompts the user whether they need to call emergency rescue. If the user selects yes, the user terminal device dials the emergency rescue number. If the user selects no, the user terminal device prompts the user to manually trigger the disposal of the battery module pack. If the user chooses not to manually trigger the disposal of the battery module pack, the user terminal device can prompt the user of the expected loss.

[0089] In this optional embodiment, after the battery module pack in a faulty state fails to separate, a rescue alert is transmitted to the terminal device. The user can then make an emergency rescue call through the user terminal device, thereby enabling timely handling of the faulty battery module pack and improving vehicle safety.
