Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0031] Figure 1This is a flowchart of a new energy vehicle early warning method provided by an embodiment of the present invention. This embodiment is applicable to the situation of new energy vehicle early warning. The method can be executed by a new energy vehicle early warning device. The new energy vehicle early warning device can be implemented in the form of hardware and / or software and can be integrated into an electronic device. For example, the electronic device can be a device with communication and computing capabilities, such as a vehicle-mounted device. Figure 1 As shown, the method includes:

[0032] S110: When the vehicle is in sleep mode, obtain the temperature of the driving battery pack in real time.

[0033] The vehicle hibernation can be considered as the whole controller in the vehicle entering a low power consumption state when the vehicle is not in use. The driving battery pack can be used to provide power to the vehicle.

[0034] In this embodiment, when the whole vehicle is in a dormant state, the temperature of the driving battery pack can be detected in real time through the temperature sensing system, so that the temperature of the driving battery pack can be obtained in real time.

[0035] S120: If the temperature exceeds a set threshold, the vehicle terminal is awakened.

[0036] In this embodiment, there is no limitation on the specific value of the set threshold, for example, it can be 50°C, and the normal temperature of the driving battery pack can be 0°C to 40°C. Specifically, if the temperature of the driving battery pack detected by the temperature sensing system exceeds the set threshold, the temperature can be considered as an abnormal temperature, and the abnormal temperature can be sent to the vehicle communication terminal through the temperature sensing system via a hard line, so that the vehicle terminal is awakened by the hard line signal.

[0037] S130: Send the temperature to the vehicle-mounted terminal, so that the vehicle-mounted terminal executes a graded warning mechanism according to the temperature.

[0038] Among them, the graded warning mechanism can be a corresponding warning measure for temperatures within different ranges, for example, it can be divided into three different levels of warning mechanisms: mild, moderate and severe.

[0039] Specifically, when the vehicle-mounted terminal is awakened successfully, the temperature may be sent to the vehicle-mounted terminal, so that the vehicle-mounted terminal executes a corresponding early warning mechanism according to the temperature.

[0040] Optionally, the method of implementing a graded warning mechanism based on temperature can be: if the temperature is within the first range, the first-level warning mechanism is executed; if the temperature is within the second range, the second-level warning mechanism is executed; if the temperature is within the third range, the third-level warning mechanism is executed; wherein the first-level warning mechanism is lower than the second-level warning mechanism, and the second-level warning mechanism is lower than the third-level warning mechanism.

[0041] The first range may be 50°C to 60°C, the second range may be 60°C to 80°C, and the third range may be above 80°C. The first-level warning mechanism may indicate a mild warning alarm, the second-level warning mechanism may indicate a moderate warning alarm, and corresponding cooling measures may be initiated at the same time. The third-level warning mechanism may indicate the most serious warning alarm. If the temperature of the driving battery pack has a high probability of causing the car to spontaneously combust, then on the basis of initiating corresponding cooling measures, the warning information may be sent to the surrounding vehicles or other infrastructure of the current vehicle to reduce vehicle losses.

[0042] Specifically, if the temperature exceeds the set threshold, dynamic detection can be performed. If the temperature is within the first range, the first level warning mechanism is executed; if the temperature is within the second range, the second level warning mechanism is executed based on the first level warning mechanism; if the temperature is within the third range, the third level warning mechanism is executed based on the second level warning mechanism.

[0043] Optionally, the first-level warning mechanism may be implemented by sending the temperature to an associated mobile terminal via a cloud platform to remind the user that the current temperature of the driving battery pack is abnormal.

[0044] Among them, the cloud platform can be a cloud platform of a car company, which can be used to forward the warning information of the vehicle terminal. Specifically, the temperature can be sent to the cloud platform by the vehicle terminal using wireless communication (such as 4G or 5G). At this time, the temperature is within the first range. The cloud platform can forward the first-level warning information to the associated mobile terminal to remind the owner that the current drive battery pack temperature is abnormal and the owner needs to pay attention to the current abnormal information. Among them, the first-level warning information can be a message prompt information, such as "The current drive battery pack temperature is abnormal, temperature A".

[0045] Optionally, the second-level warning mechanism may be executed by: sending the temperature to an associated mobile terminal via a cloud platform to remind the user that the current temperature of the drive battery pack is abnormal; the vehicle-mounted terminal sends a control instruction to the drive battery pack to disconnect the drive battery pack from the vehicle according to the control instruction; and starting a cooling device to cool the drive battery pack.

[0046] The control instruction may be an instruction to disconnect the driving battery pack from the vehicle, cool the driving battery pack, etc. The cooling device may be a liquid cooling device.

[0047] Specifically, the temperature can be sent to the cloud platform through the vehicle terminal using wireless communication (such as 4G or 5G). At this time, the temperature is within the second range, and the cloud platform can forward the second-level warning information to the associated mobile terminal to remind the owner that the current temperature of the driving battery pack is abnormal and that he needs to pay attention to the current abnormal information. Among them, the second-level warning information can also be a message prompt information, such as "The current driving battery pack temperature is abnormal, and the temperature is B." At the same time, a control instruction is sent to the driving battery pack through the vehicle terminal, so that the driving battery pack is disconnected from the whole vehicle according to the control instruction, and the driving battery pack starts the cooling device according to the control instruction to cool the driving battery pack. In this embodiment, the vehicle terminal sends an instruction to disconnect the driving battery pack from the whole vehicle, which can avoid abnormal battery pack temperature caused by other in-vehicle controllers.

[0048] Optionally, the third-level warning mechanism may be executed by: the vehicle-mounted terminal sends a control instruction to the drive battery pack to disconnect the drive battery pack from the entire vehicle according to the control instruction; the cooling device is started to cool the drive battery pack; the vehicle wireless communication V2X module is started to broadcast the current vehicle's location information to the roadside unit and / or moving vehicles within a set range.

[0049] The V2X module can be a module that enables a vehicle to communicate with any object that can exchange information through vehicle wireless communication. For example, it can enable vehicles to exchange information with each other or with roadside units. Roadside units can be an important part of the intelligent transportation system and can monitor various vehicle states through communication with vehicles.

[0050] Specifically, the temperature can be sent to the cloud platform by the vehicle terminal by wireless communication. If the temperature at this time is within the third range, the cloud platform can forward the third-level warning information to the associated mobile terminal to remind the owner that the current temperature of the driving battery pack is abnormal. Among them, the third-level warning information can also be a message prompt information, such as "the current driving battery pack temperature is abnormal, the temperature is C". At the same time, a control instruction is sent to the driving battery pack through the vehicle terminal, so that the driving battery pack is disconnected from the whole vehicle according to the control instruction, and the driving battery pack starts the cooling device according to the control instruction to cool the driving battery pack. On the basis of the above operation, the vehicle terminal can also trigger its own V2X function, and broadcast the current vehicle's location information and abnormal temperature through the vehicle wireless communication V2X method to the roadside unit within the set range (for example, 300 meters) of the current vehicle and / or the vehicle with the vehicle wireless communication V2X module in motion. At the same time, the green wave speed guidance and other functions of the vehicle wireless communication V2X technology are used to control the current traffic flow and plan safe routes, so that the relevant vehicles can avoid dangerous situations. In this embodiment, in the third-level warning mechanism, the V2X function of the vehicle terminal is triggered to reduce vehicle losses.

[0051] Optionally, the third-level warning mechanism may be implemented by sending the third-level warning information to vehicles within a set distance from the current vehicle via a public warning platform.

[0052] Specifically, if there are still dormant vehicles around the current vehicle, which is equivalent to vehicles that cannot receive the broadcast V2X information, the location information and abnormalities of the current vehicle can be sent to the cloud platform through the vehicle terminal, and the cloud platform will urgently send the third-level warning information to the public warning platform. The public warning platform synchronizes the information to the owners of vehicles within the set distance from the current vehicle by dialing or text messaging. Among them, the cloud platform stores the location information of vehicles within the set distance from the current vehicle, and the owners of vehicles within the set distance from the current vehicle upload the vehicle location information to the cloud platform before parking and turning off the engine. The public warning platform can be understood as a platform with functions similar to 114. The set distance can be 20 meters. In this embodiment, sending the third-level warning information to vehicles within the set distance from the current vehicle through the public warning platform can reduce vehicle losses and curb the further spread of the fire.

[0053] The technical solution of the embodiment of the present invention obtains the temperature of the driving battery pack in real time when the vehicle is dormant; if the temperature exceeds the set threshold, the vehicle terminal is awakened; the temperature is sent to the vehicle terminal, so that the vehicle terminal executes a graded warning mechanism according to the temperature. The above technical solution can make phased response measures according to the temperature response graded warning mechanism, which can play a timely and effective warning role and effectively reduce the losses of surrounding vehicles.

[0055] The temperature sensing module 202 is used to detect the temperature of the driving battery pack 201 in real time. If the temperature exceeds the set threshold, the vehicle terminal 203 is awakened and the temperature is sent to the vehicle terminal 203; the vehicle terminal 203 is used to execute a graded warning mechanism according to the temperature; the cloud platform 205 is used to receive the warning information sent by the vehicle terminal 203, and send the warning information to the mobile terminal 204; the public warning platform 206 is used to receive the warning information sent by the vehicle terminal 203, and send the warning information to vehicles within a set distance from the current vehicle; the cooling device 207 is used to cool the driving battery pack 201.

[0056] In this embodiment, an independent temperature sensing module is used, which is directly connected to the vehicle terminal through a hard wire, and a cooling device, such as a liquid cooling device, is installed around the driving battery pack to ensure that each module can operate independently when the vehicle is in a dormant state.

[0057] In this embodiment, the temperature of the driving battery pack can be detected in real time through the temperature sensing module. If the temperature exceeds the set threshold, the vehicle terminal is awakened and the temperature is sent to the vehicle terminal; the vehicle terminal executes a graded warning mechanism according to the temperature; the cloud platform receives the warning information sent by the vehicle terminal and sends the warning information to the mobile terminal; the public warning platform receives the warning information sent by the vehicle terminal and sends the warning information to vehicles within a set distance from the current vehicle; the cooling device cools the driving battery pack. The vehicle can maintain communication with surrounding vehicles without waking up the entire vehicle, and the warning information can be sent to the associated mobile terminal and surrounding vehicles in a timely manner, and further risks caused by waking up the entire vehicle when the driving battery pack is abnormally high in temperature can be avoided.

[0058] Optionally, the hierarchical warning mechanism includes a first-level warning mechanism, a second-level warning mechanism and a third-level warning mechanism; when the first-level warning mechanism is executed, the first-level warning information is sent to the cloud platform; when the second-level warning mechanism is executed, the second-level warning information is sent to the cloud platform, and a control instruction is sent to the drive battery pack to disconnect the drive battery pack from the whole vehicle according to the control instruction; and the cooling device is started to cool the drive battery pack; when the third-level warning mechanism is executed, the second-level warning information is sent to the cloud platform, and a control instruction is sent to the drive battery pack to disconnect the drive battery pack from the whole vehicle according to the control instruction; and the cooling device is started to cool the drive battery pack; the vehicle wireless communication V2X module is started to broadcast the current vehicle's location information to the roadside unit and / or moving vehicles within a set range; or, the third-level warning information is sent to the public warning platform.

[0059] In this embodiment, the hierarchical warning mechanism can be divided into a first-level warning mechanism, a second-level warning mechanism, and a third-level warning mechanism. The first-level warning mechanism can wake up the vehicle terminal, and send the first-level warning information to the mobile terminal through the cloud platform. The second-level warning mechanism can start the cooling device to cool the drive battery pack, and send the second-level warning information to the mobile terminal through the cloud platform. In addition to starting the cooling device and sending the third-level warning information to the mobile terminal through the cloud platform, the third-level warning mechanism will also start the vehicle wireless communication V2X module to broadcast the temperature information and location information to the roadside unit and / or the moving vehicle within the set range; if other vehicles are parked within the set distance of the current vehicle, these vehicles are in a dormant state and V2X communication cannot be performed. The vehicle terminal sends the third-level warning information to the public warning platform, and sends the third-level warning information to the vehicles within the set distance from the current vehicle through the public warning platform for emergency avoidance.
