[0074] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0075] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0076] In the prior art, when a vehicle is parked for a long time, the low-voltage battery will be exhausted, and then when the vehicle is started, there will be insufficient voltage to drive the motor, so the vehicle will not be able to start normally.

[0077] Based on this, the inventive concept of the present application is to provide a new intelligent charging control method for a vehicle. When the vehicle is parked for a long time, the user does not need to start the vehicle regularly to ensure that the low-voltage battery has power. The vehicle can automatically charge the low-voltage battery when it detects that the low-voltage battery is exhausted, thereby ensuring that the vehicle can still be started normally after being parked for a long time.

[0078] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0079] Figure 1 A schematic diagram of a flow chart of a first embodiment of a vehicle intelligent power replenishment control method provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0080] S101: The intelligent terminal periodically obtains first vehicle status information, where the first vehicle status information includes: a first door status, a first key status, and a first current voltage of a low-voltage battery on the vehicle, and the first door status is sent by a vehicle body controller.

[0081] In an embodiment of the present application, the vehicle includes: an intelligent terminal, a body controller, a vehicle controller, a battery management system, and an all-in-one controller. When the vehicle is in an ignition-off state or in a stationary storage state after charging, the intelligent terminal operates at low power consumption and periodically obtains first vehicle status information. The first vehicle status information includes: a first door status, a first key status, and a first current voltage of a low-voltage battery on the vehicle.

[0082] Optionally, in order to save energy, the smart terminal is set to a timed monitoring mode, that is, the smart terminal periodically obtains the first vehicle status information, wherein the period is set to 3 hours or 6 hours.

[0083] For example, the body control module (BCM) obtains the first door state and the first key state, and sends the first door state and the first key state to the vehicle's CAN network in the form of a controller area network (CAN) message, and the smart terminal receives the CAN message to obtain the first door state and the first key state. The smart terminal directly obtains the first current voltage of the low-voltage battery on the vehicle through the CAN network.

[0084] S102: If the first door state and the first key state are both closed, and the first current voltage is less than or equal to the first preset voltage, the intelligent terminal wakes up the vehicle controller and sends an intelligent power replenishment request to the vehicle controller.

[0085] In the embodiment of the present application, if the first door state and the first key state obtained by the smart terminal are both closed, it means that the vehicle is in an ignition-off state, and when the smart terminal detects that the first current voltage is less than or equal to the preset voltage, the smart terminal wakes up the vehicle control unit (VCU) through a hard line and sends a smart power replenishment request to the vehicle control unit. It should be noted that in the present application, except that the smart terminal wakes up the vehicle control unit through a hard line, the rest of the interactions are completed by CAN signals.

[0086] Optionally, different preset voltage values ​​are designed according to the rated voltage level of the low-voltage battery on the vehicle. When the rated voltage of the low-voltage battery is 12 volts, the preset voltage is set to 11 volts; when the rated voltage of the low-voltage battery is 24 volts, the preset voltage is set to 23 volts.

[0087] S103: The vehicle controller performs a safety check based on the intelligent power replenishment request to obtain a first safety check result. The first safety check is used to detect whether the vehicle meets the following safety conditions: the vehicle speed is 0, the vehicle is not in a plug-in power replenishment state, the vehicle has no target fault, and the vehicle's motor torque is 0. Target faults include faults related to high-voltage power-on.

[0088] In the embodiment of the present application, when the vehicle controller is awakened and receives the intelligent charging request, the vehicle controller performs a safety check on the vehicle to obtain a first safety check result. The first safety check includes: the vehicle speed is 0, the vehicle is not in the plug-in charging state, the vehicle has no target fault, the vehicle's motor torque is 0, and the target fault includes a fault related to high voltage power-on.

[0089] Among them, the vehicle speed is 0 to ensure that the vehicle is in a stationary state. If the vehicle is recharging while driving, it will interfere with the normal operation of the vehicle; the vehicle is not in a plug-in recharging state to ensure that the vehicle does not perform additional recharging operations during charging. If additional recharging operations are performed while the vehicle is charging, the low-voltage battery will be affected by the charging process and damaged; the vehicle has no target faults to ensure that all vehicle systems are in normal condition. If the vehicle has communication faults, battery faults, and other faults that prohibit high voltage, recharging will aggravate the fault and cause damage to the vehicle; the vehicle's motor torque is 0 to ensure that the vehicle's motor is not in a working state. If recharging is performed when the motor is working, it will interfere with the normal operation of the motor.

[0090] S104: If the first safety check result indicates that the vehicle meets the safety conditions, the vehicle controller wakes up the battery management system so that the battery management system provides high voltage electricity to the vehicle, and the vehicle controller controls the transformer in the all-in-one controller to convert the high voltage electricity into low voltage electricity to replenish the low voltage storage battery.

[0091] In an embodiment of the present application, if the vehicle controller obtains a first safety detection result indicating that the vehicle meets safety conditions, the vehicle controller wakes up the battery management system (BMS) through the CAN network, and the battery management system provides high voltage electricity to the vehicle by closing the high-voltage relay. At this time, the vehicle controller controls the transformer (DCDC Converter, DCDC) in the all-in-one controller to convert the high voltage electricity provided by the battery management system into low voltage electricity in order to replenish the low-voltage battery. At this time, the vehicle controller controls the high-voltage loads in the all-in-one controller except the energy storage inverter to stop, so as to avoid other unnecessary high-voltage loads consuming electricity, so as to improve the efficiency of replenishment and reduce energy loss.

[0092] In an embodiment of the present application, the intelligent terminal periodically obtains the first vehicle status information, which includes: the first door status, the first key status and the first current voltage of the low-voltage battery on the vehicle. The first door status is sent by the body controller. If the first door status and the first key status are both closed, and the first current voltage is less than or equal to the preset voltage, the intelligent terminal wakes up the vehicle controller and sends an intelligent power replenishment request to the vehicle controller. The vehicle controller performs a safety test based on the intelligent power replenishment request to obtain a first safety test result. The first safety test is used to detect whether the vehicle meets the following safety conditions: the vehicle speed is 0, the vehicle is not in a plug-in power replenishment state, the vehicle has no target fault, and the vehicle's motor torque is 0. The target fault includes a fault related to high-voltage power-on. If the first safety test result indicates that the vehicle meets the safety conditions, the vehicle controller wakes up the battery management system so that the battery management system provides high voltage electricity to the vehicle, and the vehicle controller controls the transformer in the all-in-one controller to convert the high voltage electricity into low voltage electricity to replenish the low-voltage storage battery. Compared with the prior art, which requires users to start the vehicle regularly to charge the high-voltage power battery to charge the low-voltage battery, the present application monitors the low-voltage battery voltage in real time through an intelligent terminal after the vehicle is powered off, and performs intelligent charging based on the real-time low-voltage battery voltage. There is no need for users to start the vehicle to charge the low-voltage battery, thereby avoiding the problem of the vehicle being unable to start normally when the vehicle is parked for a long time.

[0093] Figure 2 A flow chart of a second embodiment of a vehicle intelligent power replenishment control method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method comprises the following steps:

[0094] S201: If the first safety detection result indicates that the vehicle meets the safety conditions, the vehicle controller sends a power replenishment permission notification to the smart terminal.

[0095] In an embodiment of the present application, when the vehicle controller obtains the first safety detection result indicating that the vehicle meets the safety condition, the vehicle controller sends a power replenishment permission notification to the smart terminal. Optionally, the vehicle controller sends the power replenishment permission notification to the smart terminal before the vehicle controller wakes up the battery management system, or after the vehicle controller wakes up the battery management system.

[0096] S202: After receiving the charging permission notification, the smart terminal periodically records the charging information of the low-voltage battery, where the charging information includes the second current voltage.

[0097] In an embodiment of the present application, after receiving the power replenishment permission notification, the smart terminal periodically records the power replenishment information of the low-voltage battery, wherein the power replenishment information includes the second current voltage.

[0098] S203: After recording the second current voltage each time, if the second current voltage recorded last time is less than the second current voltage recorded first time, the smart terminal controls the smart power replenishment to end.

[0099] In the embodiment of the present application, if after periodically recording the second current voltage, the second current voltage recorded last time is less than the second current voltage recorded for the first time, the smart terminal determines that it is a smart power replenishment fault, and at this time the smart terminal controls the smart power replenishment to end, that is, the smart terminal sends a power replenishment stop request to the vehicle controller, so that the vehicle controller stops the current power replenishment action. For example, when the second current voltage recorded for the first time minus the second current voltage recorded for the last time is greater than 0.5 volts, the smart terminal determines that it is a smart power replenishment fault.

[0100] After recording the second current voltage each time, determining whether the intelligent power replenishment is completed further includes:

[0101] After recording the second current voltage each time, if the second current voltage recorded last time is greater than or equal to the second preset voltage, the smart terminal controls the smart power replenishment to end.

[0102] In the embodiment of the present application, after each recording of the second current voltage, if the second current voltage recorded for the last time is greater than or equal to the preset voltage, it indicates that the intelligent power replenishment is normal. At this time, the intelligent power replenishment is ended by controlling the intelligent terminal to complete the intelligent power replenishment. Optionally, the second preset voltage is designed differently according to the rated voltage level of the low-voltage battery. When the rated voltage level of the low-voltage battery is 12 volts, the second preset voltage is set to 13.8 volts; when the rated voltage level of the low-voltage battery is 24 volts, the second preset voltage is set to 27.5 volts.

[0103] When the power replenishment information also includes the current time, determining whether the intelligent power replenishment is completed also includes:

[0104] After recording the second current voltage each time, if the time difference between the last recorded current time and the first recorded current time is greater than the preset duration, and the last recorded second current voltage is less than the second preset voltage, the smart terminal records the current time as the recharging start time.

[0105] In an embodiment of the present application, when the second current voltage is periodically recorded, the current time is also recorded. After each recording of the second current voltage, if the time difference between the last recorded current time and the first recorded current time is greater than the preset duration, and the second current voltage last recorded at this time is less than the second preset voltage, the intelligent terminal determines it as a fault state, and the intelligent terminal records the current time as the recharging start time. Optionally, the preset duration is 20 minutes. That is, when the intelligent charging time reaches 20 minutes, and the voltage of the low-voltage battery is still less than the second preset voltage, the intelligent terminal determines that a fault has occurred in the intelligent charging process, and then records the current time as the recharging start time, and continues to recharge the low-voltage battery.

[0106] If the time difference between the current time last recorded after recharging and the recharging start time is greater than or equal to the preset recharging duration, and / or the second current voltage last recorded after recharging is greater than or equal to the second preset voltage, the smart terminal controls the smart charging to end.

[0107] In the embodiment of the present application, when the time difference between the current time recorded last after recharging and the recharging start time is greater than or equal to the preset recharging duration, optionally, the preset recharging duration is 10 minutes, that is, when the recharging duration is 10 minutes, the smart terminal controls the smart charging to end. And / or, when the second current voltage recorded last after recharging is greater than or equal to the second preset voltage, the smart terminal controls the smart charging to end. That is, when the recharging time reaches the preset recharging duration and / or the voltage of the low-voltage battery during the last recharging finally reaches the second preset voltage, the smart terminal controls the smart charging to end.

[0108] In an embodiment of the present application, if the first safety detection result indicates that the vehicle meets the safety conditions, the vehicle controller sends a charging permission notification to the smart terminal. After receiving the charging permission notification, the smart terminal periodically records the second current voltage and current time of the low-voltage battery, and determines whether the smart charging is over by the second current voltage and current time, which helps to avoid damage to the low-voltage battery due to long-term overcharging, thereby ensuring the safety of the low-voltage battery. When the smart charging time exceeds the preset 20 minutes, but the voltage of the low-voltage battery still cannot reach the set threshold, the low-voltage battery may have some kind of fault. At this time, the smart terminal chooses to record the current time as the recharging time, and then starts counting for 10 minutes to continue trying smart charging. By setting an additional 10-minute charging observation period, if the low-voltage battery voltage still does not increase, the smart terminal sends a charging stop request, which helps to avoid wasting unnecessary resources.

[0109] Figure 3 A schematic diagram of a flow chart of a third embodiment of a vehicle intelligent power replenishment control method provided in an embodiment of the present application, such as Figure 3As shown, the method comprises the following steps:

[0110] S301: During the intelligent charging process, the intelligent terminal periodically obtains second vehicle status information of the vehicle, where the second vehicle status information includes a second door status, a second key status, and a third current voltage of the low-voltage battery.

[0111] In the embodiment of the present application, during the intelligent charging process of the vehicle, the intelligent terminal periodically obtains the second vehicle status information of the vehicle. The second vehicle status information includes the second door status, the second key status, and the third current voltage of the low-voltage battery. The intelligent terminal periodically obtains the second door status and the second key status through the body controller and the CAN network. The intelligent terminal directly obtains the third current voltage of the low-voltage battery on the vehicle through the CAN network.

[0112] S302: If the second door state and the second key state are both open, and the third current voltage is greater than or equal to the second preset voltage, the smart terminal controls the smart charging to end.

[0113] In the embodiment of the present application, if during the intelligent charging process, the intelligent terminal obtains that the second door state and the second key state are both in the open state, the intelligent terminal controls the intelligent charging to end, ensuring that the intelligent charging operation does not occur when the vehicle is started. If during the intelligent charging process, the intelligent terminal obtains that the third current voltage is greater than or equal to the second preset voltage, the intelligent terminal controls the intelligent charging to end, avoiding overcharging and damage to the low-voltage battery.

[0114] In the embodiment of the present application, during the intelligent charging process, the intelligent terminal periodically obtains the second vehicle state information of the vehicle, and when the second door state and the second key state are in the open state, the intelligent terminal controls the intelligent charging to end, so as to avoid the intelligent charging operation when the vehicle is started, thereby causing vehicle failure or performance degradation. And during the intelligent charging process, when it is detected that the third current voltage of the low-voltage battery is greater than or equal to the second preset voltage, the intelligent terminal controls the intelligent charging to end, so as to avoid damage caused by overcharging of the low-voltage battery.

[0115] The intelligent charging process also includes:

[0116] During the intelligent charging process, the vehicle controller periodically performs safety checks on the vehicle to obtain a second safety check result.

[0117] In the embodiment of the present application, during the intelligent charging process, the vehicle controller periodically performs safety detection on the vehicle to obtain a second safety detection result. The safety detection content includes: the vehicle speed is 0, the vehicle is not in the plug-in charging state, the vehicle has no target fault, the vehicle's motor torque is 0, and the target fault includes a fault related to high voltage power-on.

[0118] If the second safety detection result indicates that the vehicle does not meet the safety conditions, the vehicle controller controls the intelligent charging to end.

[0119] In the embodiment of the present application, if the second safety detection result indicates that the vehicle does not meet the safety conditions, the vehicle controller controls the intelligent charging to end. The second safety detection result indicates that the vehicle does not meet the safety conditions means: the vehicle speed is 0, and / or the vehicle is in the plug-in charging state, and / or the vehicle has a target fault, and / or the vehicle's motor torque is not 0.

[0120] The vehicle controller controls the end of intelligent charging. The vehicle controller controls the end of intelligent charging including: the vehicle controller sends a high-voltage power-off notification to the battery management system and sends a charging stop notification to the smart terminal, and switches to a sleep state; when the battery management system receives the high-voltage power-off notification, it stops providing high-voltage power to the vehicle and switches to a sleep state; when the smart terminal receives the charging stop notification, it switches to a sleep state.

[0121] In the embodiment of the present application, if any of the following results are detected during the intelligent charging process, such as the vehicle speed is 0, and / or the vehicle is in the plug-in charging state, and / or the vehicle has a target fault, and / or the vehicle's motor torque is not 0, the vehicle controller controls the intelligent charging to end, and after the intelligent charging is completed, the intelligent terminal, the vehicle controller, and the power management system are powered off in an orderly manner, ensuring that the high-voltage power system is safely disconnected to prevent the risk of electric shock or short circuit caused by residual high-voltage electricity. And after the intelligent terminal, the vehicle controller, and the power management system are powered off in an orderly manner, they are switched to a dormant state in turn, reducing unnecessary power consumption.

[0122] Figure 4 A flowchart of a fourth embodiment of a vehicle intelligent power replenishment control method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown in the above Figure 2 or Figure 3 Based on the embodiment shown, the intelligent terminal controls the intelligent power replenishment to end, including:

[0123] S401: The intelligent terminal sends a request to stop charging to the vehicle controller and switches to a sleep state.

[0124] In the embodiment of the present application, after the intelligent terminal controls the intelligent charging to end, the intelligent terminal sends a charging stop request to the vehicle controller. After the intelligent terminal sends the charging stop request, the intelligent terminal switches to a sleep state.

[0125] S402: When receiving the request to stop charging, the vehicle controller sends a high-voltage power-off notification to the battery management system and switches to a sleep state.

[0126] In an embodiment of the present application, when the vehicle controller receives a request to stop charging, the vehicle controller sends a high-voltage power-off notification to the battery management system, and then the vehicle controller switches to a sleep state.

[0127] S403: When receiving the high-voltage power-off notification, the battery management system stops supplying high-voltage power to the vehicle and switches to a sleep state.

[0128] In an embodiment of the present application, when the battery management system receives a high-voltage power-off notification, the battery management system stops providing high-voltage power to the vehicle, and then the battery management system switches to a sleep state.

[0129] In an embodiment of the present application, after the intelligent terminal controls the intelligent charging to end, the intelligent terminal sends a charging stop request to the vehicle controller, and the intelligent terminal switches to a dormant state. When the vehicle controller receives the charging stop request, it sends a high-voltage power-off notification to the battery management system, and the vehicle controller switches to a dormant state. When the battery management system receives the high-voltage power-off notification, it stops providing high-voltage electricity to the vehicle, and the battery management system switches to a dormant state. After the intelligent charging is completed, the intelligent terminal, the vehicle controller, and the power management system are powered off in an orderly manner, ensuring that the high-voltage power system is safely disconnected and preventing the risk of electric shock or short circuit caused by residual high-voltage electricity. And after the intelligent terminal, the vehicle controller, and the power management system are powered off in an orderly manner, they switch to a dormant state in turn, reducing unnecessary energy consumption.

[0130] Figure 5 This is a schematic diagram of the intelligent power replenishment process. Figure 5As shown, the body controller will obtain the door status and key status, and the smart terminal will obtain the door status and key status from the body controller, and then the smart terminal will determine whether the door is closed. If the door is in the closed state, it will monitor whether the voltage of the low-voltage battery is less than or equal to the first preset voltage. If the voltage of the low-voltage battery is less than or equal to the first preset voltage, the smart terminal will wake up the vehicle controller through a hard line and send a smart power replenishment request message to the vehicle controller; if the smart terminal detects that the door is not closed, the voltage of the low-voltage battery is greater than the first preset voltage, or the vehicle controller is not awakened, the smart terminal will continue to detect. After the vehicle controller is awakened and receives the power replenishment request, it first determines the vehicle condition and whether the power replenishment operation can be performed. If it is not satisfied, the vehicle controller will not perform the high-voltage operation. If the charging request is met, the vehicle controller will first wake up the battery management system to high voltage. High voltage can only make the transformer in the all-in-one controller high voltage, and other accessories are prohibited from high voltage. During the charging process, the vehicle controller continuously monitors whether the charging request is met. If the charging request is not met, the vehicle controller actively disconnects the transformer and requests the battery management system to power off in an orderly manner. After the smart terminal wakes up the vehicle controller, the smart terminal waits for the vehicle controller to feedback whether to perform the charging instruction. If there is no feedback after waiting for 1 minute, or the feedback is a prohibition of charging instruction, the smart terminal stops outputting the wake-up signal and sends a request to stop charging. If the smart terminal receives a feedback instruction to allow charging, the smart terminal continues to output the wake-up signal and the request for charging, and continues to judge whether the conditions for terminating charging are met. If they are met, the wake-up signal is stopped and the request to stop charging is sent. If not, the wake-up signal and the request for charging are continuously output.
