[0025] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1 The present disclosure provides a method for managing power supply of a vehicle battery, which is applied to the vehicle battery. The method includes:

[0027] Step S1: Send the working status information of the vehicle battery to the cloud server through the vehicle gateway, wherein the working status information of the vehicle battery includes the power status of the vehicle battery.

[0028] In some embodiments of this formula, see Figure 2, step S1, comprising:

[0029] Step S11, collecting the power of the vehicle battery as the working status information of the vehicle battery, wherein the power is obtained according to at least one of the current, voltage and power signals of the vehicle battery.

[0030] Step S12: Send the collected working status information of the vehicle battery to the cloud server through the vehicle gateway.

[0031] The disclosed embodiment obtains the power of the vehicle battery through at least one of the vehicle battery current, voltage, and power signal, and then uses the power of the vehicle battery as the working state information of the vehicle battery. The disclosed embodiment can easily and accurately obtain the power of the vehicle battery, thereby realizing the feedback of the working state information of the vehicle battery to the cloud server through the power of the vehicle battery.

[0032] In the specific implementation of some embodiments of the present disclosure, step S11 is specifically:

[0033] The power of the vehicle battery is collected according to a preset period as the working status information of the vehicle battery.

[0034] Those skilled in the art can set the size of the preset period as needed.

[0035] The disclosed embodiment collects the power of the vehicle battery in a preset period as the working status information of the vehicle battery, so that the power status of the vehicle battery can be accurately known.

[0036] Step S2, receiving a low power mode instruction sent by a cloud server through a vehicle gateway, wherein the low power mode instruction is an instruction triggered when the cloud server predicts that the vehicle battery is in a low power state according to a preset low power algorithm.

[0037] The disclosed embodiment enables the cloud server to obtain the working status information of the vehicle battery, that is, the power level of the vehicle battery, through the vehicle gateway, and then use a preset low-power algorithm to predict whether the vehicle battery is in a low-power state.

[0038] In the specific implementation of some embodiments of the present disclosure, the preset power-deficit algorithm includes at least one of the following:

[0039]

[0040] Estimated time in low power mode = (SOCt2*total battery capacity-reserved power) / power consumption in ultra-low power mode;

[0041] Low power mode increase time = low power mode estimated time - remaining battery life;

[0042] Among them, T1 is the first time point, SOCt1 is the power of the vehicle battery at the first time point, T2 is the second time point, SOCt2 is the power of the vehicle battery at the second time point, and the reserved SOC is the power that needs to be reserved for the vehicle battery.

[0043] The cloud server of the disclosed embodiment obtains the remaining usage time of the vehicle battery, the estimated time of the low power mode, and the increased time of the low power mode through the above-mentioned preset low power algorithm to predict whether the vehicle battery is in a low power state. If it is in a low power state, the user's mobile terminal is notified.

[0044] The disclosed embodiment adopts a cloud server to calculate a preset low-battery algorithm, and can use the powerful computing power of the cloud server to quickly predict the low-battery state of the vehicle battery.

[0045] After the user's mobile terminal receives the power-deficit judgment information sent by the cloud server, it generates a power-deficit prompt according to the obtained power-deficit judgment information, such as Figure 3 shown.

[0046] Step S3: reducing the power supply of the vehicle battery according to the low power consumption mode instruction, and shutting down the low voltage electrical appliances of the vehicle to enter the low power consumption mode.

[0047] The user uses a mobile terminal to turn on the ultra-low power mode switch, and sends a low power mode command to the vehicle battery through the cloud server, reducing the power supply of the vehicle battery and shutting down the vehicle's low-voltage electrical appliances to enter low power mode.

[0048] The power supply management scheme for the vehicle battery provided in the embodiment of the present disclosure sends the working status information of the vehicle battery to the cloud server through the vehicle gateway, wherein the working status information of the vehicle battery includes the power status of the vehicle battery. The cloud server triggers a low power mode instruction when predicting that the vehicle battery is in a low power state according to a preset low power algorithm. The cloud server sends the low power mode instruction to the vehicle battery through the vehicle gateway, reduces the power supply of the vehicle battery, and shuts down the low-voltage electrical appliances of the vehicle to enter a low power mode. In the case of a low power battery of the vehicle, the embodiment of the present disclosure causes the battery to enter a low power mode, thereby reducing the occurrence of the situation where the vehicle battery cannot start the vehicle, and the vehicle can be started without road rescue, thereby improving the user experience.

[0049] In the specific implementation of some embodiments of the present disclosure, see Figure 4 , the method further comprises:

[0050] Step S4, receiving the low power mode shutdown command sent by the cloud server through the vehicle gateway, controlling the vehicle battery to discharge normally, and turning on the vehicle's low-voltage electrical appliances to complete normal operation.

[0051] In the disclosed embodiment, when a user uses a mobile terminal to turn off the ultra-low power consumption mode switch, that is, when the user needs to start the vehicle, the mobile terminal sends a low power consumption mode turn-off instruction to the cloud server, and the cloud server sends a low power consumption mode turn-off instruction to the vehicle gateway, controls the vehicle battery to discharge normally, and turns on the vehicle's low-voltage electrical appliances to complete normal work, so that the user can use the vehicle normally.

[0052] See also Figure 5 The embodiment of the present disclosure also provides a method for managing power supply of a vehicle battery, which is applied to a mobile terminal, and the method includes:

[0053] Step T1, obtaining low-battery judgment information sent by a cloud server, and generating a low-battery prompt based on the obtained low-battery judgment information, wherein the low-battery judgment information is an instruction triggered when the cloud server predicts that the vehicle battery is in a low-battery state based on a preset low-battery algorithm.

[0054] Step T2: according to the received instruction to start the low power consumption mode, send the low power consumption mode instruction to the cloud server, and let the cloud server send the low power consumption mode instruction through the vehicle gateway to reduce the power supply of the vehicle battery, so that the low-voltage electrical appliances of the vehicle are turned off and enter the low power consumption mode.

[0055] In the specific implementation of some embodiments of the present disclosure, the preset power-deficit algorithm includes at least one of the following:

[0056]

[0057] Estimated time in low power mode = (SOCt2*total battery capacity-reserved power) / power consumption in ultra-low power mode;

[0058] Low power mode increase time = low power mode estimated time - remaining battery life;

[0059] Among them, T1 is the first time point, SOCt1 is the power of the vehicle battery at the first time point, T2 is the second time point, SOCt2 is the power of the vehicle battery at the second time point, and the reserved SOC is the power that needs to be reserved for the vehicle battery.

[0060] The cloud server of the disclosed embodiment obtains the remaining usage time of the vehicle battery, the estimated time of the low power mode, and the increased time of the low power mode through the above-mentioned preset low power algorithm to predict whether the vehicle battery is in a low power state. If it is in a low power state, the user's mobile terminal is notified.

[0061] The disclosed embodiment adopts a cloud server to calculate a preset low-battery algorithm, and can use the powerful computing power of the cloud server to quickly predict the low-battery state of the vehicle battery.

[0062] After the user's mobile terminal receives the power-deficit judgment information sent by the cloud server, it generates a power-deficit prompt according to the obtained power-deficit judgment information, such as Figure 3 shown.

[0063] The power supply management scheme for the vehicle battery provided in the embodiment of the present disclosure sends the working status information of the vehicle battery to the cloud server through the vehicle gateway, wherein the working status information of the vehicle battery includes the power status of the vehicle battery. The cloud server triggers a low power mode instruction when predicting that the vehicle battery is in a low power state according to a preset low power algorithm. The cloud server sends the low power mode instruction to the vehicle battery through the vehicle gateway, reduces the power supply of the vehicle battery, and shuts down the low-voltage electrical appliances of the vehicle to enter a low power mode. In the case of a low power battery of the vehicle, the embodiment of the present disclosure causes the battery to enter a low power mode, thereby reducing the occurrence of the situation where the vehicle battery cannot start the vehicle, and the vehicle can be started without road rescue, thereby improving the user experience.

[0064] See also Figure 6 , the specific implementation of the embodiment of the present disclosure is further explained below through the signal transmission relationship.

[0065] The vehicle battery collects its electric quantity as the working state information of the vehicle battery, wherein the electric quantity is obtained according to at least one of the vehicle battery current, voltage and power signal.

[0066] The vehicle battery sends the collected working status information to the vehicle gateway.

[0067] The vehicle gateway sends the working status information to the cloud server.

[0068] If the cloud server predicts that the vehicle battery is not in a low-battery state using a preset low-battery algorithm, a high-battery reminder is sent to the user's mobile terminal.

[0069] If the cloud server predicts that the vehicle battery is in a low-battery state using a preset low-battery algorithm, a low-battery reminder is sent to the user's mobile terminal.

[0070] After the user's mobile terminal receives the low-battery judgment information sent by the cloud server, it generates a low-battery prompt based on the obtained low-battery judgment information.

[0071] The user uses a mobile terminal to turn on the ultra-low power mode switch and sends a low power mode command to the vehicle battery through the cloud server.

[0072] The vehicle's battery reduces its power supply and shuts down the vehicle's low-voltage electrical appliances to enter low-power consumption mode.

[0073] When the user uses the mobile terminal to turn off the ultra-low power consumption mode switch, that is, when the user needs to start the vehicle, the mobile terminal sends a low power consumption mode turn-off instruction to the cloud server.

[0074] The cloud server sends a command to shut down the low-power mode to the vehicle gateway, controls the vehicle battery to discharge normally, and turns on the vehicle's low-voltage electrical appliances to complete normal work, so that users can use the vehicle normally.

[0075] For the above method, see Figure 7 The present disclosure also provides a power supply management device for a vehicle battery, which is applied to a vehicle battery, and the device includes:

[0077] The command receiving module 702 is used to receive a low power mode command sent by the cloud server through the vehicle gateway, and the low power mode command is a command triggered when the cloud server predicts that the vehicle battery is in a low power state according to a preset low power algorithm;

[0078] The mode switching module 703 is used to reduce the power supply of the vehicle battery according to the low power consumption mode instruction, and shut down the low-voltage electrical appliances of the vehicle to enter the low power consumption mode.
