[0026] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] Please read Figure 1 , Figure 1 The present application also provides a battery charging determination method, which can be applied to electronic devices. The method includes:

[0028] Step S110: Acquire the state of charge parameter SOC and the state of function parameter SOF of the target battery in the target device.

[0029] The target battery refers to a battery that needs to be charged, which can be a rechargeable battery such as a lithium battery, a nickel-cadmium battery, a nickel-metal hydride battery or a lithium polymer battery. The voltage corresponding to the target battery can be 5V, 12V or 24V, etc. In one embodiment of the present application, the target battery can be a 12V lithium battery. The target device refers to a device that is installed with the target battery, which can be any electronic device such as a vehicle or a robot that needs to be installed with the target battery.

[0030] The target battery can provide power for some electrical components in the target device, such as the target device's security system (e.g., anti-theft system, alarm system, etc.), remote communication system, environmental monitoring system, and basic electronic control system (e.g., systems for monitoring and maintaining basic vehicle functions, such as the braking system in the vehicle), etc. The target battery can not only provide the necessary power support when the target device is in working state, but also provide power for the above-mentioned electrical components in non-working state (e.g., dormant state), ensuring the safety of the target device and its ability to start at any time.

[0031] In one possible implementation manner, the target device is a vehicle, which includes a braking system, and the target battery is used to provide electrical energy to the braking system.

[0032] In this embodiment, the braking system may specifically include a parking brake and a service brake, and the target battery is connected to the parking brake and the service brake, respectively, to provide electrical energy to the parking brake and the service brake, respectively.

[0033] Figure 2 A schematic diagram showing a target battery powering the service brake and the parking brake in the braking system of a vehicle is shown.

[0034] The state of charge parameter of the target battery is used to indicate the ratio of the remaining power of the target battery to the power when it is fully charged, and the value thereof ranges from 0% to 100%.

[0035] The functional status parameter of the target battery is used to evaluate the overall working status of the target battery, and represents the ability of the target battery to meet the load demand under the status, and its value is also 0% to 100%.

[0036] Among them, the functional state parameter (SOF, State of Function) of the target battery is an indicator obtained by comprehensive calculation based on the power state parameter (SOC, State of Charge) and the health state parameter (SOH, State of Health). Exemplarily, SOF=w1×SOC+w2×SOH; wherein w1 is the weight of SOC, w2 is the weight of SOH, and since the value ranges of SOC and SOH are both from 0% to 100%, correspondingly, the value range of SOF is also from 0% to 100%.

[0037] In one possible implementation, the functional state parameters and charge state parameters of the target battery can be expressed as follows: Figure 2 The battery parameter detector in the electronic device can be obtained by Figure 2 (not shown) is connected so that the controller can obtain the functional status parameters and charge state parameters obtained by the battery parameter detector for the target battery.

[0038] In one possible implementation, the above step S110 may be to obtain the state of charge parameter of the target battery in the target device, and if the state of charge parameter is less than a reference threshold, obtain the working state parameter of the target device and the functional state parameter of the target battery in the target device.

[0039] The above reference threshold may be 50%, 55% or 45%, etc., which is not specifically limited in the embodiment of the present application.

[0040] Step S120: determining whether a charging condition for charging the target battery is met according to the state of charge parameter SOC and the functional state parameter SOF.

[0041] The charging condition may be some pre-set charging rules related to the state of charge parameters and the function state parameters.

[0042] In one possible implementation, the recharging condition may be that the recharging condition is determined to be met when the functional status parameter SOF is in a first preset value range and the state of charge parameter SOC is less than a first preset threshold, and the recharging condition is determined to be met when the functional status parameter SOF is in a second preset value range and the state of charge parameter is less than a second preset threshold, wherein the first preset value range does not overlap with the second preset value range, and the first preset threshold is different from the second preset threshold.

[0043] Exemplarily, when the function status parameter is between 85% and 100% and the state of charge parameter SOC is less than 20%, it is determined that additional power is needed; when the function status parameter is between 70% and 85% and the state of charge parameter SOC is less than 30%, it is determined that additional power is needed.

[0044] In another possible implementation, the charging condition may also be related to the working state of the target device. For example, when the target device is in the working state, if the function state parameter SOF is in the first preset value interval and the state of charge parameter SOC is less than the first preset threshold, it is determined that the charging condition is met, and when the function state parameter SOF is in the second preset value interval and the charge parameter is less than the second preset threshold, it is determined that the charging condition is met, wherein the first preset value interval does not overlap with the second preset value interval, and the first preset threshold is different from the second preset threshold. When the target device is in the dormant state, if the function state parameter SOF is in the first preset value interval and the state of charge parameter SOC is less than the third preset threshold, it is determined that the charging condition is met, and when the function state parameter SOF is in the second preset value interval and the charge parameter is less than the fourth preset threshold, it is determined that the charging condition is met, wherein the first preset value interval does not overlap with the second preset value interval, and the first preset threshold, the second preset threshold, the third preset threshold and the fourth preset threshold may be different from each other.

[0045] In the above implementation, by setting the threshold range of SOC and SOF to determine whether to supplement power, it is possible to avoid the target battery from operating for a long time in a low SOC or low SOF state, which helps to extend the service life of the target battery. Avoiding the target battery from operating for a long time in a low SOC or low SOF state can also avoid unnecessary supplement power, which helps to extend the service life of the target battery. Ensuring that the target battery has sufficient power to support the load demand in the working state improves the reliability of the operation of the target device.

[0046] Step S130: When the charging condition is met, the target battery is charged.

[0047] When the target battery is recharged, the target battery may be recharged by a power supply device in the target device.

[0048] To ensure that the target device can recharge the target battery, before performing the recharging of the target battery, the method further includes: obtaining the voltage of the power supply device, and if the power supply voltage reaches a first preset voltage value, controlling the power supply device to recharge the target battery.

[0049] The first preset voltage value may be 5V, 7V or 12V, etc., which is set according to the rated voltage of the power supply device during normal power supply. When the power supply voltage reaches the first preset voltage value, it indicates that the voltage of the power supply device is stable and high enough. At this time, the target battery is supplemented by the power supply device, which can ensure that the charging current is more stable, thereby improving the charging efficiency.

[0050] Considering that the target device may use different power supply devices in different states, for example, if the target device is a vehicle, industrial equipment or medical equipment, please refer to Figure 2 If the target device is in a working state, it can work normally when powered by the main power supply of the target device. At this time, the power supply device includes a main power supply and a voltage conversion module connected to the main power supply. The above step S130 includes: if the state of the target device is a working state, control the voltage conversion module to convert the first voltage provided by the main power supply in the target device into a second voltage to replenish the target battery and replenish the target battery.

[0051] It is worth mentioning that the main power supply in the target device refers to the device or equipment that provides the main power in the target device. If the target device is a car, the main power supply can be a power battery pack; if the target device is industrial equipment or a smart home, the main power supply can be a three-phase AC power supply, a DC power supply or a mains power supply.

[0052] It should be understood that different main power sources correspond to different voltage conversion modules. For example, if the main power source is a power battery or a DC power source, a DC-DC converter (Direct Current to Direct Current Converter) can be used for voltage conversion; if the main power source is a three-phase AC power source or AC power, an AC-DC converter (Alternating Current to Direct Current Converte) can be used for voltage conversion.

[0053] For example, if the target device is a car, and its main power source is a power battery pack, when the target battery needs to be recharged, the voltage conversion module can be, for example, a DC-DC converter, for converting a first voltage provided by the main power source into a second voltage (e.g., 12V voltage) suitable for charging the target battery, thereby recharging the 12V backup lithium battery or other battery (target battery).

[0054] When the target device is in a dormant state and the main power supply is no longer supplying power, the power supply device further includes an energy storage module. The above step S130 includes: if the target device is in a dormant state, controlling the energy storage module to recharge the target battery.

[0055] The energy storage module may be a supercapacitor, a flow battery, a sodium-sulfur battery, a fuel cell, or other device that is different from the above-mentioned main power source and is used for energy storage. It is not specifically limited here and can be set according to actual needs. Figure 3 As shown, the energy storage module is obtained by connecting multiple supercapacitors in series.

[0056] In one possible implementation mode, an electronic switch may be connected between the energy storage module and the battery. The electronic switch may be any one of a relay, a field effect transistor or a triode. The control end of the electronic switch is connected to the controller, the input end is connected to the energy storage module, and the output end is connected to the battery. When determining that the target battery needs to be recharged, the controller may send a control signal to the electronic switch to turn on the input and output ends of the electronic switch, thereby controlling the energy storage module to recharge the target battery.

[0057] It should be understood that the non-working state and working state of the target device are a set of relative concepts. In this example, the working state means that the target device is running and requires relatively high voltage or power support. At this time, the target device is mainly powered by a power battery pack or a main power supply. At this time, if the target device is a vehicle, its operating system usually includes a power system, an on-board electrical system, and a control system that can ensure the normal driving of the vehicle. In addition, there may be some low-power systems powered by a 12V backup lithium battery or a similar small battery (i.e., the target battery in this application) in the target device. The non-working state means that the target vehicle is in a dormant state, and only some electrical components of the target device are running in a low-power mode, and the running electrical components are powered by a 12V backup lithium battery or a similar small battery (i.e., the target battery in this application) in the target device. At this time, if the target device is a vehicle, its operating system usually includes one or more of a safety system (e.g., an anti-theft alarm system) and a basic electronic control system (a control system for monitoring and maintaining basic vehicle functions, such as a vehicle's brake control system).

[0058] By adopting the above method, the state of charge parameter reflects the remaining power of the target battery, and the functional status parameter reflects the health status of the target battery. Combining the working parameters of the target device, the state of charge parameters and the functional status parameters of the target battery can accurately determine whether the battery needs to be recharged, avoid unnecessary charging, and thus reduce energy waste.

[0059] See also Figure 4 In one possible implementation, the above step S120 includes: step S121 and step S122.

[0060] Step S121: If the state of the target device is a working state, determine a first reference state of charge parameter according to a first preset parameter and the functional state parameter, wherein the first preset parameter indicates the power consumption of the target device when the target device is stationary for a preset period of time in the working state.

[0061] The method of determining the first reference state of charge parameter of the target device in the working state according to the functional state parameter and the first preset parameter of the target battery can be to add the functional state parameter to the first preset parameter to obtain the first reference state of charge parameter of the target device in the working state. If the first reference state of charge parameter is less than or equal to the state of charge parameter of the target device, supplementary power is required to ensure that the target battery can support the load.

[0062] The first preset parameter can be the ratio of the electric energy consumed by the target battery when it is stationary for a preset period of time when the target device is in working state to the total capacity of the target battery, or it can be the ratio of the electric energy consumed by the target battery when it supplies power to the corresponding electrical components (such as the aforementioned safety system and basic electronic control system, etc.) for a preset period of time when the target device is in working state to the total capacity of the target battery.

[0063] The above-mentioned preset duration can be 3 days, 5 days or 8 days, etc., and the above-mentioned first preset parameter can be pre-set, such as 7%, 8% or 9%, etc., which is not specifically limited here. Among them, the first preset parameter setting basis can be determined based on the detection result obtained by the battery parameter detector of the target battery when the target device is in the working state, or it can be obtained based on the historical usage statistics of the target battery when the target device is in the working state, which is not specifically limited here.

[0064] Step S122: determining whether a charging condition for charging the target battery is met according to the state of charge parameter of the target battery and a first reference state of charge parameter; if the state of charge parameter of the target battery is less than the first reference state of charge parameter, determining that the charging condition is met.

[0065] Exemplarily, if the capacity of the target battery is 60Ah and the remaining power is 30Ah, that is, the target battery SOC value is 50%, in addition, if the target battery SOF value is 44%, if the target battery is in working condition and the target device is in working condition, the target battery consumes 8% of its power during a preset static period of time (e.g., X days), then the first reference state of charge parameter is SOF+8%, that is, 52%. Obviously, the SOC of the target battery is 5% and less than 52%, then it can be determined that the target battery needs to be charged.

[0066] After determining the first reference state of charge parameter according to the functional status parameter and the first preset parameter, when the state of charge parameter of the target battery is less than the first reference state of charge, it is confirmed that the target battery needs to be recharged, which fully considers the power consumption of the target battery of the target device in the working state, that is, if the target battery cannot meet the load demand after the preset time, it needs to be recharged, and if it can meet the load demand after the preset time, it does not need to be recharged, so that the recharge logic of the target device is closer to the actual demand. In addition, in the above process, the SOF and SOC values ​​of the target battery are dynamically changing. By adopting the above implementation method, the first reference state of charge parameter can be dynamically determined, and it can be accurately judged when recharging is needed in the working state.

[0067] In one possible implementation, the above step S120 may further include: step S123 and step S124.

[0068] Step S123: If the state of the target device is a dormant state, determine a second reference state of charge parameter according to a second preset parameter and the functional state parameter, wherein the second preset parameter indicates the power consumption of the target battery when the target device is in a dormant state and is at rest for a preset period of time. Specifically, the functional state parameter and the second power consumption parameter of the target battery may be added to obtain the second reference state of charge parameter of the target device in a non-working state.

[0069] The second preset parameter may be pre-set, such as 4%, 5% or 6%, etc., which is not specifically limited here. The second preset parameter setting basis may be determined based on the detection result of the battery parameter detector performing power consumption detection on the target battery when the target device is in a non-working state, or may be obtained based on the historical usage statistics of the target battery when the target device is in a non-working state, which is not specifically limited here.

[0070] Step S124: Determine whether the charging condition for charging the target battery is met according to the state of charge parameter of the target battery and the second reference state of charge parameter. If the state of charge parameter of the target battery is less than the second reference state of charge parameter, it is determined that the target battery needs to be charged. Exemplarily, if the capacity of the target battery is 60Ah and the remaining power is 30Ah, that is, the SOC value of the target battery is 50%. In addition, if the SOF value of the target battery is 44%, if the target battery is in a non-working state and the target device is in a non-working state, the power consumption (second preset parameter) of the target battery within a preset static time (such as 3 days, 5 days or 7 days, etc.) is 5%, then the first reference state of charge parameter is SOF+5%, that is, 49%. Obviously, the SOC of the target battery is 50% and not less than 49%, then it can be determined that the target battery does not need to be charged.

[0071] It should be noted that in the above two implementations, when the target device is in a non-working state, the controller may be in a dormant state. If the controller is in a dormant state, the dormant target device can execute the aforementioned logic of determining whether the target battery needs to be recharged, and when it is determined that the target battery needs to be recharged, control the dormant controller to self-wake up, and after completing the self-wake up, execute the step of controlling the energy storage module to recharge the target battery. Therefore, when the target device is in a network dormant state, the above recharge method can be used without other nodes maintaining the network during the recharge process, reducing the power consumption of the entire vehicle.

[0072] By obtaining a second reference state-of-charge parameter based on the power consumption and functional state parameters of the target battery of the target device in a non-working state within a preset time, it is determined that the target battery needs to be recharged when the state-of-charge parameter of the target battery is less than the second reference state-of-charge parameter, that is, if the target battery cannot meet the load demand after the preset time, it needs to be recharged, and if it can meet the load demand after the preset time, it does not need to be recharged, so that the recharge logic of the target device is closer to the actual demand. In addition, in the above process, the SOF and SOC values ​​of the target battery are dynamically changing. By adopting the above implementation method, the second reference state-of-charge parameter can be dynamically determined, and it can be accurately determined when recharging is needed in the dormant state.

[0073] By adopting the above steps S121-S124, full consideration is given to the different energy consumption of the target battery within a preset time period when the target device is in a working state and a non-working state, so that different parameter ranges are set for SOC and SOF in the working state and the non-working state, so that differentiated power replenishment is performed according to SOC and SOF and their corresponding parameter ranges in the working state and the non-working state, ensuring that the target battery has sufficient power to support the necessary load requirements in the non-working state, improving the safety of the target device and the ability to start at any time, which helps to extend the service life of the target battery.

[0074] See also Figure 5 In one possible implementation, before executing step S130, the method further includes:

[0075] Step S140: Acquire fault detection parameters of the target battery.

[0076] The fault detection parameters may include one or more of battery voltage, current, temperature, and health status.

[0077] Step S150: determining a fault detection result of the target battery according to a preset fault reference parameter and the fault detection parameter, wherein the fault detection result indicates whether the target battery has a charging fault.

[0078] Among them, the target battery failure can be determined when the internal resistance determined based on the battery voltage and current is greater than the preset internal resistance, or the battery failure can be determined when the battery temperature is greater than the preset temperature threshold, or the battery failure can be determined when the health status does not meet the preset health status.

[0079] The above-mentioned method of determining a fault is merely illustrative and is not specifically limited in this embodiment.

[0080] Step S160: If it is determined that the target battery does not have a charging fault, determine the state of the target device according to the working state parameter, and the state of the target device includes a sleep state or a working state.

[0081] The working state parameter of the target device can be used to characterize whether the target device is in an operating state. That is, the working parameter of the target device can be a parameter that directly reflects the working state of the target device, and the working parameter of the target device can also have a corresponding relationship with the working state. For example, different working parameters can correspond to the state of whether the device is working. Based on this, in one possible implementation, the above step S160 can be to determine whether the target device is in an operating state according to the corresponding relationship between the preset working parameter and the working state and the working parameter of the target device.

[0082] For example, when the target device is a vehicle, its status parameters include a high-voltage working status parameter, indicating whether the high-voltage system of the vehicle is in an activated state; an ignition switch status parameter, indicating whether the ignition switch is on; a driving status parameter, indicating whether the vehicle is driving; and a power gear type, indicating whether the gear of the vehicle is an accessory gear, an open gear, or a closed gear, etc. When the target device is an industrial device or a medical device, its status parameters include a power status, indicating whether the power supply of the target device is normal; and an operation status parameter, indicating whether the device is in an operating state.

[0083] In one possible implementation, if the target device is a vehicle, the operating status parameter of the target device includes the power gear of the vehicle. If the power gear of the vehicle is the accessory gear or the open gear, it is determined that the vehicle is in a working state; if the power gear of the vehicle is the closed gear, it is determined that the vehicle is in a non-working state.

[0084] In another possible implementation, if the target device is a vehicle, the operating status parameter of the target device includes a high-voltage operating status parameter. If the high-voltage operating status parameter indicates that the high-voltage system of the vehicle is in an activated state, the vehicle is in a working state. If the high-voltage operating status parameter indicates that the high-voltage system of the vehicle is not in an activated state, the vehicle is in a non-working state.

[0085] By adopting the above-mentioned steps S110-S160 of the present application, the battery recharge determination method, since the state of charge parameter reflects the remaining power of the target battery, and the functional status parameter reflects the health status of the battery and the remaining power of the battery, the working parameters of the target device, the state of charge parameters of the target battery and the functional status parameters are respectively combined to jointly determine whether the target device needs to be recharged when it is in a working state or a non-working state. The health status and remaining power of the target battery and the different working states of the target device are taken into consideration to achieve a more accurate determination of whether the target battery needs to be recharged, ensuring that the target battery is in a working state or a non-working state. As long as it is possible to accurately determine whether it is time to replenish power (i.e., accurately determine whether replenishing power is needed) based on the charge state parameters and functional state parameters of the target battery, the corresponding replenishing method can be used for replenishing power (i.e., when the target device is in a working state, the voltage conversion module is controlled to convert the first voltage provided by the main power supply in the target device into a second voltage for replenishing power to the target battery and replenish the target battery, and when the target device is in a non-working state and the target battery needs to be replenished, the energy storage module is controlled to replenish the target battery), thereby ensuring that the target battery can reliably support the load demand at any time, thereby improving the reliability of the target device.

[0086] In one possible implementation, the method further includes: obtaining charging parameters for charging the target battery; if it is determined according to the charging parameters that the target battery is fully charged, controlling the energy storage module and the voltage conversion module to stop charging the target battery.

[0087] By controlling the energy storage module and the voltage conversion module to stop replenishing the target battery when the replenishment is completed, overcharging of the target battery and waste of electric energy can be effectively avoided.

[0088] The above-mentioned charging parameters may be the charging duration, or may be one or more of the charging voltage at multiple moments during the charging process or the state of charge parameters at multiple moments during the charging process.

[0089] In one possible implementation, if the charging parameter is the charging duration, if it is determined that the charging duration reaches a preset duration, it can be determined that the charging of the target battery is completed. The preset duration can be 30 minutes, 1 hour, or 2 hours, etc., which can be set according to actual needs.

[0090] In another possible implementation, if there is a state of charge parameter greater than a preset threshold value among the state of charge parameters at multiple moments, it is determined that the target battery is fully charged, and the energy storage module and the voltage conversion module are controlled to stop charging the target battery.

[0091] The above-mentioned preset threshold can be 95%, 97% or 100%, etc., which can be set according to actual needs. When there is a state of charge parameter greater than the preset threshold during the charging process, it indicates that the target battery has been fully charged. At this time, stopping the charging of the target battery can avoid the target battery from running for a long time at an excessively high SOC, which helps to extend the service life of the target battery.

[0092] In another possible implementation, the above-mentioned charging parameters may include a state of charge parameter during the charging process and a charging voltage at multiple moments. If the state of charge parameter during the charging process reaches a preset parameter threshold, or if it is determined based on the charging voltage at the multiple moments that the charging voltage within a continuous preset time period is less than a second preset voltage value, the power supply device is controlled to stop charging the target battery, and the second preset voltage value is less than the first preset voltage value.

[0093] Among them, when the SOC during the charging process reaches the preset parameter threshold or the charging voltage within the continuous preset time is less than the second preset voltage value, it means that the battery is close to full charge. At this time, stopping charging can effectively avoid the occurrence of overcharging, enhance the safety and reliability of the charging process, and also promote battery health management.

[0094] In another possible implementation, if it is determined based on the replenishment voltage at multiple moments that the replenishment voltage is lower than the preset voltage value for a continuous set time period, it is determined that the target battery replenishment is completed, and the energy storage module and the voltage conversion module are controlled to stop replenishing the target battery.

[0095] The above-mentioned preset voltage threshold can be set according to actual needs, such as the saturated charging voltage of the target battery during normal charging minus a set voltage value, and the set voltage value can be determined according to actual needs. By adopting the above method, the charging process can be stopped in time, avoiding long-term overcharging of the target battery, extending the life of the target battery, and avoiding unnecessary waste of electricity.

[0096] For example, see Figure 6 , taking the target device as a vehicle and the target battery as a 12V lithium battery, using the controller in the above power replenishment control system to replenish the target battery as an example, the specific power replenishment process is as follows:

[0097] Determine whether the state of charge parameter SOC of the lithium battery is less than a reference threshold.

[0098] If the state of charge parameter of the vehicle is less than a reference threshold, the power level of the vehicle is obtained.

[0099] The power gear position may be an accessory gear position, an on gear position, or an off gear position. Determine whether the power gear position of the vehicle is an off gear position.

[0100] If the power gear is in the off gear, the vehicle is in a network dormant state. If the power gear is not in the off gear (ie, in the accessory gear or the on gear), the vehicle is in a high-voltage working state.

[0101] If the vehicle is determined to be in a high-voltage working state according to the power level, at this time, all control components of the vehicle are in an awake state (that is, the controller in the power replenishment control system is in an awake state). At this time, the controller determines whether the 12V lithium battery in the vehicle meets the first power replenishment condition according to the state of charge parameter and functional state parameter of the vehicle in the high-voltage working state, wherein the first power replenishment condition is: state of charge parameter SOC≤[functional state parameter SOF+8% (first power consumption parameter)]&&12V lithium battery has no charging-related faults&&output voltage of the voltage conversion module>Y1 volts. Among them, the specific value of Y1 can be set according to actual needs, as long as it can ensure that the voltage output by the voltage conversion module can charge the target battery.

[0102] If the first power replenishment condition is met, the controller can control the voltage conversion module to convert the first voltage provided by the main power supply in the target device into a second voltage for replenishing power for the target battery and replenish the power for the target battery.

[0103] If the vehicle is determined to be in a network dormant state according to the power level, the controller may also be in a dormant state. The controller may determine whether the 12V lithium battery in the vehicle meets the second power replenishment condition according to the state of charge parameter and function state parameter of the vehicle in the network dormant state in the dormant state, wherein the second power replenishment condition is: state of charge parameter SOC ≤ [function state parameter SOF + 5% (second power consumption parameter)] && 12V lithium battery has no charging-related faults && discharge voltage of energy storage module > Y2 volts. The specific value of Y2 can be set according to actual needs, as long as the energy storage module can charge the target battery at a discharge voltage of Y2 volts.

[0104] If the second power replenishment condition is met, the controller performs self-wake-up, and after completing self-wake-up, the controller controls the energy storage module to replenish power to the target battery.

[0105] During the charging process of the target battery, the charging parameters are obtained, and it is determined whether the charging completion condition is met according to the charging parameters, wherein the charging completion condition is: SOC ≥ X% || battery charging voltage ≤ Y3 volts, and lasts for t min, wherein X is a preset threshold, Y3 is a preset voltage value, and t min is a set duration.

[0106] If the charging completion condition is met, the energy storage module and the voltage conversion module are controlled to stop charging the target battery.

[0107] By adopting the above method, when the vehicle is in a high-voltage working state, charging of the target battery can be stopped immediately when the power replenishment exit threshold is reached, thereby reducing the power consumption of the entire vehicle; when the vehicle is in a network sleep state, the power replenishment times are reduced by lowering the power replenishment entry and exit thresholds. In addition, since the controller has a self-wake-up function, other nodes are not required to maintain the network during the power replenishment process, thereby reducing the power consumption of the entire vehicle.

[0108] It should be understood that, unless otherwise specified herein, the execution of these steps is not strictly limited in order, and these steps may be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but may be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least a portion of the steps or stages in other steps.
