DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the embodiments and the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood as the common meanings understood by those with ordinary skills in the art to which the embodiments of the present application belong.

The terms “upper”, “lower”, “left”, “right” and the like only represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships may also change accordingly.

[0019] In the process of long-term placement of the vehicle, in order to ensure the safety and reliability of the vehicle, the vehicle will be periodically self-checked by the vehicle wake-up mechanism to exclude potential risks. In the related art, the wake-up mechanism of the vehicle mainly relies on the central electronic module (CEM, Central Electronic Module), and the wake-up process will first wake up the low-voltage battery management system. If the low-voltage battery has sufficient power, the system will wake up the vehicle network, and wake up the related modules and systems through the vehicle network to perform self-checking to ensure that the vehicle is in a safe state, for example, to check whether there is a risk of thermal runaway. If the low-voltage battery has low power, the system will wake up the high-voltage battery management system through the vehicle network, and control the high-voltage battery to charge the low-voltage battery to increase the power of the low-voltage battery and ensure the subsequent normal start and operation of the vehicle.

[0020] In the related art, the wake-up mechanism of the CEM mainly includes a wake-up mechanism based on low-voltage battery voltage and a timing wake-up mechanism. The wake-up mechanism based on low-voltage battery voltage refers to that the CEM remains in a working state during the vehicle hibernation process and monitors the voltage of the low-voltage battery in real time. Once the voltage drops to a preset threshold, the CEM will immediately wake up the vehicle for corresponding operation. This mechanism can respond to voltage changes in a timely manner and ensure that the vehicle can take measures when the battery power is insufficient. The timing wake-up mechanism refers to that the CEM enters a hibernation state together with the vehicle when the vehicle is hibernating, and automatically wakes up at a preset time interval (such as 12 hours). This mechanism wakes up the CEM through a fixed time interval to perform necessary checks and operations, thereby reducing the energy consumption caused by continuous monitoring.

[0021] However, the above two wake-up mechanisms have related problems. The wake-up mechanism based on low-voltage battery voltage has the following problems: the CEM does not hibernate during the vehicle hibernation process, and it needs to monitor the low-voltage battery voltage in real time. Although this mechanism can respond to voltage changes in a timely manner, it has obvious energy consumption problems. Specifically, the CEM needs to maintain a certain power consumption during the monitoring process, which increases the static power consumption of the vehicle. Especially when the vehicle is parked for a long time or in a hibernation state, the cumulative power consumption significantly affects the service life of the low-voltage battery and the overall energy efficiency of the vehicle. In the timing wake-up mechanism, the CEM hibernates together with the vehicle, and the setting of the wake-up interval length is usually based on a fixed period or a preset threshold. For example, the CEM may automatically wake up once every certain time (such as 12 hours). This fixed wake-up strategy cannot be optimized according to the actual low-voltage battery state, the vehicle use environment, and the current state of the vehicle, resulting in excessive frequency of wake-up in some cases, and missing critical monitoring moments in other cases.

[0022] In addition, neither of the above wake-up mechanisms can be adjusted according to different types of batteries (such as SLI, Starting, Lighting, and Ignition, starting, lighting, and ignition battery; EFB, Enhanced Flooded Battery, enhanced flooded battery; AGM, Absorbent Glass Mat, absorbent glass mat battery). Different types of low-voltage batteries (such as lead-acid batteries, lithium-ion batteries, etc.) exhibit different performance characteristics under different environmental conditions (such as temperature, humidity, etc.). For example, lithium-ion batteries may experience a decrease in available capacity in low-temperature environments, while lead-acid batteries may accelerate aging in high-temperature environments. Therefore, different wake-up interval lengths may be required. The limitations of the above wake-up mechanisms limit the applicability and flexibility of different types of low-voltage batteries in vehicle configurations.

[0023] The applicant finds that after the vehicle is woken up from the hibernation state, by comprehensively analyzing the voltage parameter of the low-voltage battery, the environmental parameter of the vehicle, and the number of wake-ups, the wake-up interval time length after this hibernation can be accurately determined. This scheme ingeniously combines the actual environmental conditions of the vehicle and the specific conditions of the battery, and realizes the dynamic adjustment of the wake-up interval time length. And the specific conditions of the battery also consider real-time data and historical data, which makes the adjustment mechanism be able to flexibly calculate the most suitable wake-up interval time length for the current vehicle state, thereby effectively preventing the power consumption caused by invalid wake-ups due to fixed wake-up strategies. In addition, by reducing unnecessary wake-up times, this scheme significantly improves the energy efficiency of the vehicle and prolongs the service life of the low-voltage battery.

[0024] The applicant further finds that by determining the correction coefficients for the voltage parameter and the environmental parameter of the vehicle based on the type of the low-voltage battery, the calculation of the wake-up interval time length can be further optimized. By setting correction coefficients for these parameters, the control system of the vehicle can more accurately adjust the wake-up interval time length to adapt to the actual needs under different battery types and environmental conditions.

[0025] In addition, it should be noted that, as mentioned earlier, the vehicle includes a low-voltage battery for powering the CEM, and a high-voltage battery for supplementing power to the low-voltage battery. For the convenience of description, in the following embodiments, the low-voltage battery can also be referred to as the first battery, and the high-voltage battery can also be referred to as the second battery.

[0026] The following embodiments will be described in conjunction with the accompanying drawings. Figures 1-4 The present application is described in conjunction with the accompanying drawings.

[0027] In some embodiments, a vehicle wake-up control method is executed by a central electronic module (CEM) or other controllers independent of the central electronic module. For the convenience of subsequent description, the method is executed by the central electronic module (CEM) as an example without special explanation.

[0028] The vehicle wake-up control method includes: S101, in response to the vehicle being woken up from the hibernation state, obtaining the voltage parameter of the first battery, the environmental parameter of the vehicle, and the number of wake-ups.

[0029] The hibernation state refers to a low-power mode entered by the vehicle when it is parked or not used for a long time in order to reduce power consumption. In this state, unnecessary systems and modules such as infotainment systems and air conditioning systems are turned off.

[0030] The wake-up refers to the process of activating the vehicle from the sleep state. The wake-up can be triggered by various factors. Common wake-up scenarios include: a timed wake-up, in which the vehicle automatically wakes up according to a preset or calculated wake-up interval length, and performs a state check; a voltage change wake-up, in which the wake-up is triggered when the voltage of the low-voltage storage battery drops to a preset threshold; and a user operation wake-up, in which the wake-up is triggered by user operations such as opening the vehicle door or pressing the start button. It should be noted that the present application is mainly based on the wake-up triggered by the calculated wake-up interval length, and the calculation of the wake-up interval length itself has already taken into account the voltage change of the low-voltage storage battery, and does not involve user operations.

[0031] The voltage parameter of the first storage battery exemplarily includes the voltage before the last sleep of the vehicle and the voltage after the current wake-up. The voltage before the last sleep is the voltage value of the first storage battery before the vehicle enters the sleep state, which can be recorded when the vehicle enters the sleep state. The voltage after the current wake-up is the voltage value of the first storage battery after the vehicle wakes up from the sleep state, which is measured in real time when the vehicle wakes up. Exemplarily, the CEM can measure the voltage of the first storage battery through a voltage detection circuit.

[0032] The environmental parameter of the vehicle is exemplified by the environmental temperature, which can be the temperature inside the vehicle, the temperature outside the vehicle, or the fusion temperature (such as the average) of the two. The vehicle can be equipped with a temperature sensor for monitoring the environmental temperature inside and outside the vehicle.

[0033] The number of wake-ups of the vehicle refers to the cumulative number of wake-ups from the sleep state during the storage process of the vehicle. The CEM of the vehicle can be built-in with a counter, which is automatically increased by 1 each time the vehicle wakes up from the sleep state, and records the number of wake-ups each time in the non-volatile memory of the vehicle.

[0034] In this step, when the vehicle wakes up from the sleep state, the CEM will first determine the voltage parameter of the first storage battery, including the voltage before the last sleep and the voltage after the current wake-up. At the same time, the CEM will obtain the environmental parameter of the vehicle, such as the environmental temperature, which is monitored in real time through the temperature sensors inside and outside the vehicle. In addition, the CEM will also accumulate the number of wake-ups, record each wake-up event through the built-in counter, and store the data in the non-volatile memory. These parameters will be comprehensively analyzed to prepare for determining the wake-up interval length after the current sleep.

[0035] S102, determining the wake-up interval length based on the voltage parameter of the first storage battery, the environmental parameter of the vehicle, and the number of wake-ups.

[0036] The wake-up interval length is the length of time from the end time of the current wake-up to the start time of the next wake-up, or the sleep length of the vehicle after the current wake-up.

[0037] Specifically, the voltage parameter of the first battery includes a current voltage, a history voltage, and a first power compensation voltage threshold preset for the first battery. The step can specifically include: determining a first voltage difference based on the current voltage and the history voltage; determining a second voltage difference based on the current voltage and the first power compensation voltage threshold; and determining the wake-up interval duration based on the first voltage difference, the second voltage difference, an environmental parameter of the vehicle, and a wake-up frequency, wherein the history voltage is the voltage of the first battery before the vehicle enters the sleep state, the first voltage difference, the environmental parameter, and the wake-up frequency are directly proportional to the wake-up interval duration, and the second voltage difference is inversely proportional to the wake-up interval duration.

[0038] The current voltage is the voltage after the vehicle is woken up this time, the history voltage is the voltage of the first battery before the vehicle enters the sleep state, in other words, the voltage before the vehicle enters the sleep state last time, and the first power compensation voltage threshold is preset for the first battery, that is, when the voltage of the first battery reaches the first power compensation voltage threshold, the first battery can be powered by the second battery if the conditions allow.

[0039] The following is a description of the relationship between the first voltage difference, the second voltage difference, the environmental parameter, the wake-up frequency, and the wake-up interval duration: When the battery discharge current is stable and consistent, the battery voltage is directly proportional to the battery power, and the higher the voltage, the more power. Therefore, the greater the difference between the current voltage of the first battery and the first power compensation voltage threshold (i.e., the first voltage difference), the longer the time that can be placed. In other words, the first voltage difference is directly proportional to the wake-up interval duration. This means that when the power of the first battery is sufficient, the vehicle can remain in the sleep state for a longer period of time, reducing unnecessary wake-ups.

[0040] Within a certain period of time, the greater the voltage drop (i.e., the second voltage difference) between the current voltage and the history voltage of the first battery, the greater the energy loss during the last sleep period of the vehicle (e.g., due to partial controller continuous power supply, electronic equipment not completely closed, remote information processing system abnormal wake-up, etc.) or the risk of battery aging, resulting in an increased risk of power loss. Therefore, the wake-up interval needs to be reduced and the detection frequency needs to be increased in order to timely discover and handle problems. That is, the second voltage difference is inversely proportional to the wake-up interval duration. This helps to take timely measures when the battery power drops rapidly to avoid excessive discharge of the battery.

[0041] The available capacity, charge-discharge capability and temperature of the first battery are strongly related. When the temperature is low, the available capacity and the battery charge acceptance capability decrease, and therefore, the detection frequency needs to be increased to protect the performance of the battery and avoid damage to the battery due to low power. When the temperature is high, the available capacity and the battery charge acceptance capability increase, and therefore, the detection frequency needs to be reduced to save the power of the battery. That is, the environmental parameter is proportional to the length of the wake-up interval. This means that in a low-temperature environment, the vehicle needs to wake up more frequently to monitor the battery status to ensure its normal operation.

[0042] The more the number of timed wake-ups during the vehicle placement time, the more stable the vehicle state, and the less likely to trigger power compensation for the first battery, which can be placed for a longer time. At this time, the risk of power loss is small, and the detection frequency can be reduced to prolong the wake-up interval. That is, the number of wake-ups is proportional to the length of the wake-up interval. This shows that if the vehicle is in good condition after multiple wake-ups, it means that its battery and related systems are working properly, and the time interval for the next wake-up can be appropriately extended to reduce energy consumption.

[0043] In this step, the central electronic module (CEM) of the vehicle can dynamically adjust the length of the wake-up interval according to the voltage parameter of the first battery, the environmental parameter of the vehicle and the number of wake-ups. This dynamic adjustment mechanism is the key to achieving precise wake-up and low-power management based on power compensation for the first battery. In this way, the vehicle can effectively solve the problems existing in related technologies, such as invalid wake-up, excessive energy consumption and delayed power compensation. Specifically, the length of the wake-up interval obtained in this step is affected by multi-dimensional voltage parameters, including the current voltage, the historical voltage and the first power compensation voltage threshold preset for the first battery. This means that the CEM can flexibly adjust the length of the wake-up interval according to the changes of these parameters to adapt to different vehicle states and environmental conditions. Therefore, the CEM in this embodiment can enter a sleep state with the vehicle, without the need to monitor the voltage parameter of the first battery in real time during the sleep period. This design not only reduces energy consumption, but also improves the intelligence level of the vehicle and the user experience. The CEM only starts monitoring the voltage parameter of the first battery after the vehicle wakes up, thereby further optimizing the energy consumption management of the vehicle to ensure that the vehicle can maintain the necessary functions with the lowest energy consumption during the sleep period, while being able to wake up in time and perform necessary operations when needed.

[0044] S103, after the vehicle is put to sleep again, the vehicle is woken up again based on the length of the wake-up interval.

[0045] In this step, after the vehicle enters the sleep state again, the vehicle is woken up again according to the wake-up interval time calculated in S102. Specifically, if the self-check result of the vehicle during the last wake-up shows that everything is normal, and no user operation or environmental change triggers other wake-up conditions, the vehicle will enter the sleep state again and start waiting for the next wake-up interval time. When the wake-up interval time calculated in S102 arrives, the vehicle will automatically wake up from the sleep state to perform the necessary checks and responses. At this time, the vehicle will re-execute S101 and S102 to calculate the next wake-up interval time again according to the current first battery voltage parameter, vehicle environmental parameter, and wake-up number, etc., thereby realizing dynamic management of vehicle sleep and wake-up, ensuring that the energy consumption of the vehicle during sleep is effectively controlled, and at the same time, the vehicle can respond to possible problems or needs in time.

[0046] The vehicle wake-up control method of the embodiment includes: in response to the vehicle being woken up from the sleep state, obtaining the voltage parameter of the first battery, the environmental parameter of the vehicle, and the wake-up number; determining the wake-up interval time based on the voltage parameter of the first battery, the environmental parameter of the vehicle, and the wake-up number; and after the vehicle sleeps again, waking up the vehicle again based on the wake-up interval time. This method dynamically adjusts the wake-up interval time by considering the voltage parameter of the first battery, the environmental parameter of the vehicle, and the wake-up number, thereby realizing precise wake-up and low-power management. This not only reduces invalid wake-up and unnecessary energy consumption, but also prolongs the service life of the first battery and reduces maintenance costs. In addition, through the above intelligent wake-up mechanism, the vehicle can adapt to different use environments and states, ensure good state in long-term parking or sleep state, and maximize the availability of the vehicle to improve user experience.

[0047] In some embodiments, the determination of the wake-up interval time in S102 based on the first voltage difference, the second voltage difference, the environmental parameter of the vehicle, and the wake-up number includes: determining the first voltage difference, the second voltage difference, the first correction coefficient corresponding to the environmental parameter of the vehicle, the second correction coefficient, and the third correction coefficient based on the type of the first battery; and determining the wake-up interval time based on the first voltage difference and the first correction coefficient, the second voltage difference and the second correction coefficient, the environmental parameter of the vehicle and the third correction coefficient, and the wake-up number.

[0048]

[0049] wherein: : the wake-up interval time, : the current voltage value, Vthreshold : the first power compensation voltage threshold; the difference between the first voltage difference and the second voltage difference is the second voltage difference; and Vthreshold the difference between the first voltage difference and the second voltage difference is the second voltage difference.N : the number of wake-ups; Tref : the current ambient temperature, T : the standard temperature, which can be set to 25℃; : the second voltage difference; k1, k2, k3 respectively, the first correction coefficient, the second correction coefficient and the third correction coefficient, which can be calibrated and matched according to the type of the battery (such as SLI, EFB, AGM).

[0050] Exemplarily, the first battery is an AGM battery, k1 = 300, k2 = -0.01, k3 = 2, Vthreshold = 12.0V; when N = 2 times, the current voltage Vcurrent = 12.5V, the current temperature Tref = 35℃, and the historical voltage (i.e. the voltage before the vehicle last entered the sleep state) is 12.8V; the above values are brought into the formula to obtain the wake-up interval duration :

[0051] The vehicle wake-up control method in the embodiment significantly improves the accuracy and adaptability of the calculation of the wake-up interval duration by introducing three correction coefficients (k1, k2, k3) and calibrating and matching in advance according to the type of the battery (such as SLI, EFB, AGM). Specifically, the first correction coefficient (k1) adjusts the first voltage difference, the second correction coefficient (k2) adjusts the second voltage difference, and the third correction coefficient (k3) adjusts the environmental parameter. This dynamic adjustment mechanism based on the type of the battery enables the calculation of the wake-up interval duration to more accurately reflect the performance and state of different batteries, thereby achieving more efficient energy consumption management and more accurate battery maintenance.

[0052] In some embodiments, the response to the vehicle being woken up from the sleep state in S101 is to obtain the voltage parameter of the first battery, the environmental parameter of the vehicle and the number of wake-ups, including: In response to the vehicle being woken up from the sleep state after a preset sleep duration, the vehicle is woken up from the sleep state and the steps of obtaining the voltage parameter of the first battery, the environmental parameter of the vehicle and the number of wake-ups are performed.

[0053] For example, the preset sleep duration can be set to 3 hours. This preset sleep duration should not be too long, because at the first sleep, the vehicle has not collected enough data to assess the state of the battery, such as whether there is aging or poor low-temperature performance. Therefore, after the first sleep, the vehicle will automatically wake up after 3 hours, perform a preliminary state check, and perform the steps of obtaining the voltage parameter of the first battery, the environmental parameter of the vehicle, and the wake-up frequency, wherein the historical voltage is the voltage of the first battery at the time of vehicle power-off. Based on the calculation formula of the wake-up interval duration in the foregoing embodiment, the next wake-up interval duration after the current wake-up is calculated. For example, the vehicle is powered off and enters the first sleep at 22:25 on June 19, the preset sleep duration is 3h, the first wake-up start time is 1:25 on June 20, the wake-up interval duration is calculated to be 49.4h by obtaining the voltage parameter, the environmental parameter of the vehicle, and the wake-up frequency, the first wake-up time lasts for 5 minutes, and the first wake-up end time is 1:30 on June 20. The wake-up interval duration is 49.4h, and the second wake-up time is 2:54 on June 22. Compared with the traditional strategy of waking up once every 12h, the number of wake-ups is significantly reduced, and the energy consumption is reduced.

[0054] In this embodiment, by setting a shorter preset sleep duration for preliminary wake-up after the first sleep, the basic state of the battery can be quickly evaluated, and potential problems such as battery aging or poor low-temperature performance can be found in time. This strategy not only ensures the safety and reliability of the vehicle in the early stage, but also provides basic data for subsequent precise wake-up control. Starting from the second sleep, the vehicle uses a dynamic calculation method for the wake-up interval duration, which can accurately adjust according to the actual state of the battery and environmental conditions. This method significantly reduces unnecessary wake-up times.

[0055] In some embodiments, the step of S103 of waking up the vehicle again based on the wake-up interval duration after the vehicle sleeps again includes: determining whether the wake-up interval duration is within a preset interval; in response to determining that the wake-up interval duration is within the preset interval, waking up the vehicle again based on the wake-up interval duration after the vehicle sleeps again; and in response to determining that the wake-up interval duration is outside the preset interval, waking up the vehicle again based on a preset sleep duration after the vehicle sleeps again.

[0056] Exemplarily, the minimum wake-up interval length can be set as 1 hour, and the maximum wake-up interval length can be set as 168 hours. If the calculated wake-up interval length is within this interval, the vehicle will wake up again based on this wake-up interval length after sleeping again. If the calculated wake-up interval length is out of this interval, the vehicle will wake up again based on the preset sleep length (e.g., 12 hours) after sleeping again. This mechanism can effectively prevent the formula calculation value from being out of a reasonable range, ensuring that the vehicle's wake-up mechanism is both flexible and reliable, avoiding problems such as excessive energy consumption or battery depletion caused by too short or too long wake-up interval lengths.

[0057] In this embodiment, by setting the preset interval of the minimum wake-up interval length and the maximum wake-up interval length, the vehicle can effectively prevent the calculated wake-up interval length from being out of a reasonable range. When the calculated wake-up interval length is within this interval, the vehicle will wake up again based on this wake-up interval length, thereby achieving precise energy consumption management and battery maintenance. When the calculated wake-up interval length is out of this interval, the vehicle will wake up again based on the preset sleep length, which not only avoids the problem of excessive energy consumption caused by too short wake-up interval lengths, but also prevents the risk of battery depletion caused by too long wake-up interval lengths, ensuring that the vehicle's wake-up mechanism is both flexible and reliable, effectively improving the stability and safety of the vehicle during sleep, optimizing energy consumption management, and prolonging the service life of the battery.

[0058] The above embodiments describe how to determine and execute the wake-up interval length based on the voltage parameter of the first battery, the environmental parameter of the vehicle, and the wake-up times. The following embodiments describe how to perform power compensation when the current voltage is less than or equal to the preset first power compensation voltage threshold during a wake-up process. This process is a key step to ensure that the battery power of the vehicle is maintained at a safe level during sleep. By accurately monitoring the voltage of the first battery and compensating the power in time when the voltage is lower than the safety threshold, the vehicle can effectively avoid excessive discharge of the battery and prolong the service life of the battery. At the same time, this intelligent power compensation mechanism can also ensure that the vehicle can start quickly when needed, improving the reliability and user experience of the vehicle.

[0059] In some embodiments, the method further comprises: S201, after the vehicle is woken up from the sleep state, in response to determining that the current voltage is less than or equal to the preset first power compensation voltage threshold, determining whether a power compensation precondition is met; The power compensation precondition includes at least one of the following: Condition one: the power supply mode of the whole vehicle is powered off, that is, there is no user vehicle use case; that is, the vehicle will not be disturbed by user operation, avoiding the power fluctuation and power supply interruption caused by user starting the vehicle or using the vehicle-mounted equipment during power supply. At the same time, the powered-off state also means that most of the systems of the vehicle are in sleep or off state, which helps to reduce unnecessary energy consumption and ensure that the power supply process can be carried out efficiently, so as to more accurately supplement the required power of the first storage battery and maintain the normal operation and starting ability of the vehicle.

[0060] Condition two: the power supply permission signal of the second storage battery is activated, which is activated to represent that before entering the sleep state (i.e., before the last sleep), the second storage battery is fault-free and its voltage is higher than the first power supply voltage threshold. Among them, the CEM obtains the voltage of the second storage battery through the BMS. Since the current BMS has not been awakened, only the data before the last sleep can be used. For example, the first power supply voltage threshold is 12V, the voltage of the second storage battery is 350V, 350V>12V, and no fault signal of the BMS is received, then the power supply permission signal of the second storage battery in the CEM is activated. Exemplarily, the CEM is provided with a power supply enable flag bit about the second storage battery, when the flag bit changes from 0 to 1, it indicates that the power supply permission signal of the second storage battery in the CEM is activated. That is, it indicates that the second storage battery is in good working condition and can safely supplement the power of the first storage battery.

[0061] Condition three: the power supply permission signal of the first storage battery is activated, which is activated to represent that the first storage battery is fault-free and its power supply interval duration is longer than the preset interval duration. Exemplarily, the preset interval duration is 10min, the CEM is provided with a timer which starts counting after the first storage battery finishes power supply, and when it reaches 10min and no fault of the first storage battery is monitored, the power supply permission signal of the first storage battery in the CEM is activated. Exemplarily, the CEM is provided with a power supply enable flag bit about the first storage battery, when the flag bit changes from 0 to 1, it indicates that the power supply permission signal of the first storage battery in the CEM is activated. That is, it indicates that the first storage battery is in good working condition and can be supplemented by the second storage battery.

[0062] S202A, in response to determining that the power supply precondition is satisfied, waking up the whole vehicle network to enable the second storage battery through the whole vehicle network and supplementing the first storage battery through the second storage battery.

[0063] The vehicle network refers to a network system inside a vehicle for connecting various systems and communicating, usually including CAN bus, LIN bus, FlexRay, etc., for realizing data transmission and communication between various electronic control units (ECUs) of the vehicle. The process of waking up the vehicle network is usually initiated by the central electronic module (CEM) or similar control unit of the vehicle. When the CEM detects the need to wake up the vehicle network, it will send a specific wake-up signal to each node on the network, including but not limited to the battery management system (BMS), power management system, body control system, etc. After receiving the wake-up signal, these nodes will switch from low-power mode to normal working mode, preparing for data communication and function execution.

[0064] Specifically, when the CEM determines that the pre-recharge condition is met, it will send a wake-up instruction to the BMS through the vehicle network. After receiving the instruction, the BMS will wake up from the sleep state and begin monitoring and managing the state of the high-voltage battery. The BMS will check the voltage, temperature, current, and other parameters of the high-voltage battery to ensure that the battery is in a normal state and is ready for recharging. After the BMS enables the high-voltage battery (i.e., the second battery), the DC / DC converter will start working to convert high-voltage electricity into low-voltage electricity and charge the low-voltage battery (i.e., the first battery) through the vehicle's low-voltage power supply system. This process will continue until the voltage of the low-voltage battery reaches the preset charging completion threshold. During the entire recharging process, the BMS and CEM will continuously monitor and control the recharging process to ensure the safety and efficiency of the recharging operation.

[0065] The recharging of the first battery by the second battery further includes: in response to determining that the recharging duration reaches a preset recharging duration, stopping the recharging; and in response to determining that a preset interval duration is reached since the recharging is stopped and the first battery is fault-free, activating a recharging permission signal of the first battery. Specifically, when the first battery (i.e., the low-voltage battery) is recharged by the second battery (i.e., the high-voltage battery), the system monitors the recharging duration. Once the recharging duration reaches the preset recharging duration, for example, 30 minutes, the system will automatically stop the recharging operation. This is to prevent overcharging and protect the health status of the first battery. After the recharging is stopped, the system enters a waiting state. If a preset interval duration, for example, 10 minutes, is reached since the recharging is stopped and the first battery is monitored to be fault-free during this period, the system will activate the recharging permission signal of the first battery. The activation of this signal means that the first battery is ready to accept recharging again, and also indicates that the system considers the state of the first battery to be safe and can perform the next recharging operation. This control logic not only helps to prolong the service life of the battery, but also ensures that the battery can be properly maintained and managed during long-term parking or non-use, thereby improving the overall reliability and safety of the vehicle.

[0066] S202B, in response to determining that the pre-charge condition is not met, the wake-up of the whole vehicle network is stopped.

[0067] When the CEM determines that the pre-charge condition is not met (e.g., the first battery or the second battery's charge permission signal is not activated), the whole vehicle network will not be woken up. As the first battery cannot be charged, its voltage may decrease from the first charge voltage threshold to the second charge voltage threshold, i.e., after the vehicle is woken up from the hibernation state, if the voltage of the first battery is lower than the preset second charge voltage threshold, the vehicle will hibernate and not wake up again. The second charge voltage threshold is less than the first charge voltage threshold. That is, in order to prevent the vehicle from frequently waking up invalidly when the first battery voltage is too low to recover the power through the normal charging process, energy consumption is saved and the battery is protected from over-discharge. This mechanism ensures that the vehicle can safely enter the hibernation state when the battery power is insufficient, avoiding system failure or damage caused by low power, and also provides an effective management strategy for long-term parking and maintenance of the vehicle.

[0068] Alternatively, S202B can also be described as: in response to determining that the pre-charge condition is not met, the communication module is woken up through the whole vehicle network to send warning information to the user through the communication module. When the CEM determines that the pre-charge condition is not met, only by waking up the whole vehicle network to further wake up the communication module to send warning information to the user, the warning information is an example of "12V battery power is too low and cannot be charged, please repair to avoid affecting subsequent vehicle use". This mechanism not only informs the user of the current low power state of the vehicle in a timely manner, but also allows the user to take measures in advance, such as arranging for charging or checking the health of the battery. In this way, the vehicle can effectively communicate with the user when it cannot recover the power through the normal charging process, ensuring that the user will not be trapped in a difficult situation due to the low power state of the vehicle. This design not only improves the user-friendliness of the vehicle, but also enhances the safety and reliability of the vehicle, providing a more intelligent vehicle management method for users.

[0069] In this embodiment, by setting the pre-charge condition, it is ensured that the whole vehicle network will only be woken up and the charging process will only be started when certain safety and state requirements are met, which effectively avoids unnecessary energy consumption and system wear. For example, only when the whole vehicle power mode is powered down, the second battery is fault-free and has sufficient voltage, and the first battery's charge interval meets the preset condition, the charging operation will be performed. When the pre-charge condition is not met, the vehicle will not wake up the whole vehicle network, thereby avoiding the risk of invalid wake-up and over-discharge. By setting the second charge voltage threshold, the vehicle can safely enter the hibernation state when the battery power is too low, preventing system failure or damage caused by insufficient power.
