[0002] Electric vehicles are becoming increasingly popular, and with the advancement of intelligent technology, they are becoming increasingly versatile, requiring more and more controllers. Existing electric vehicles typically have two batteries: a main battery and an auxiliary battery. When the vehicle is running, the main battery powers the vehicle controller and the auxiliary battery, while when the vehicle is off, the auxiliary battery powers the various controllers. Therefore, if the vehicle is off for extended periods, the auxiliary battery can easily become depleted, causing the vehicle management system to malfunction.

[0003] Existing technical solutions typically recharge the auxiliary battery while the vehicle is off. For example, this involves periodically waking up the vehicle to recharge the auxiliary battery. However, this recharging process only operates according to a preset cycle and does not take into account the specific state of the vehicle. For example, waking up the vehicle network when recharging conditions are not met can increase the risk of battery failure.

[0057] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0058] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0059] The driving and vehicle equipment control of electric vehicles both require power input, and the driving and vehicle equipment control have different power requirements, such as different voltages. Therefore, electric vehicles usually have two batteries, called the main battery and the auxiliary battery. The main battery can be used as a power battery to power the driving, and the auxiliary battery can be used as a storage battery to power the vehicle equipment. The main battery can also be used to charge the auxiliary battery.

[0060] Since the auxiliary battery is used to power vehicle equipment, and these equipment still requires power to operate when the vehicle is turned off, the auxiliary battery needs to continue to output power to the vehicle equipment. When the vehicle is turned off for a long time, the auxiliary battery will be exhausted due to the long-term power output. If the auxiliary battery is exhausted, it will affect the control of vehicle equipment, such as the operation of the anti-theft system and vehicle starting ignition. Therefore, in order to prevent the auxiliary battery from being exhausted, it is usually recharged when the vehicle is turned off.

[0061] Among the existing charging methods, the following two methods are mainly used for charging. One is to periodically wake up the vehicle and control the main battery to charge the auxiliary battery. Although this method can play the role of charging, its charging process is too simple. When the main battery is low on power, the vehicle is still woken up for charging, which has the risk of accelerating the vehicle's power shortage. Alternatively, when the auxiliary battery has sufficient power, the vehicle is woken up for charging, which will cause the auxiliary battery to overcharge and affect the life of the auxiliary battery. The other method is to add a voltage acquisition circuit. When it detects that the auxiliary battery voltage is less than the set value, the vehicle is woken up and the main battery is controlled to charge the auxiliary battery for a fixed period of time. This charging method uses the auxiliary battery voltage as the charging reference and does not take into account the main battery power. If the engine is off for a long time and multiple charging operations are performed, the main battery will consume a lot of power, which will affect the vehicle's mileage.

[0062] Figure 1 A schematic flow chart of a vehicle charging method provided in an embodiment of the present application.

[0063] like Figure 1 As shown, the present application discloses an embodiment, which provides a vehicle charging method, the method comprising:

[0064] S110: Acquire first power information of a first battery of the vehicle, where the first power information indicates the power level of the first battery.

[0065] Specifically, the vehicle charging method in this embodiment can be applied to entities with vehicle management capabilities, such as vehicle management systems, servers, and terminals; the scenario in which the vehicle charging method is executed can be a scenario in which the vehicle is in an off state, wherein the first battery can be any one or more batteries in the vehicle. For example, the first battery can represent a power battery that mainly plays a driving role in an electric vehicle; taking the execution entity as a server as an example, the server is in communication with the vehicle-mounted system, and the vehicle-mounted system can be a telematics box (TBOX) mounted on the vehicle. The TBOX collects the power information of the first battery through the controller area network (CAN) to obtain the first power information, and sends the first power information of the first battery to the server, so that the server obtains the first power information of the first battery of the vehicle.

[0066] S120: When the power level indicated by the first power level information is greater than a first threshold, obtaining the operating status of a control network of the vehicle, where the control network represents a controller area network of the vehicle.

[0067] S130: Determine a charging strategy corresponding to the operating state, where the charging strategy represents a method of charging the second battery to be charged.

[0068] Specifically, after obtaining the first power information of the first battery of the vehicle, it is determined whether the power represented by the first power information is greater than a first threshold, where the first threshold is a pre-set power threshold, indicating the minimum power of the first battery to maintain driving. The first threshold can be set according to different vehicles or different maximum capacities of the first battery. Therefore, it is determined whether the power represented by the first power information is greater than the first threshold, that is, whether the current power of the first battery is sufficient; when the power represented by the first power information is greater than the first threshold, it means that the current power of the first battery is relatively sufficient and has the basic power to replenish the second battery.

[0069] In addition, the second battery in this embodiment can be one or more batteries in the vehicle in addition to the first battery. For example, the second battery can be a storage battery that powers the vehicle's control devices. Since numerous control devices (e.g., sensors for detecting door status, alarms, etc.) continue to operate even when the vehicle is off, the second battery must continue to output power. The CAN network, serving as a microcontroller communication network within the vehicle, exchanges information between various onboard electronic control devices, forming the vehicle's electronic control network. For example, the engine management system, transmission controller, instrumentation, and electronic backbone systems are examples. Normally, when the vehicle is off, the CAN network enters a sleep mode, consuming very low power. However, when an anomaly occurs in the CAN network, it remains in an active mode even when the vehicle is off. At this time, the CAN network continuously collects and transmits data, consuming a high amount of power, which accelerates the power consumption of the second battery. Therefore, the power consumption rate of the second battery varies depending on whether the CAN network is abnormal or normal.

[0070] In this embodiment, when the power represented by the first power information is greater than the first threshold, it is also necessary to obtain the operating status of the vehicle's control network, the control network represents the vehicle's controller area network, and the control network here represents the CAN network, wherein the operating status may include a normal state and an abnormal state, that is, the CAN network is in a sleep mode when the vehicle is turned off, which is a normal state, and the CAN network is still in a start mode when the vehicle is turned off, which is an abnormal state; after obtaining the operating status of the CAN network, the power replenishment strategy corresponding to the operating status can be determined, and the power replenishment strategy represents the way to replenish the second battery to be replenished. For example, when the operating status is normal, it is necessary Recharging the second battery for 30 minutes can charge the second battery to 80%, allowing the second battery to continue to power the control device for 5 days. When the operating state is abnormal, if the same charging strategy mentioned above is adopted, the second battery can be charged to 80% after 30 minutes of charging. However, due to the abnormality of the CAN network, the power consumption is large, and the second battery can only continue to power the control device for 1 day. Therefore, when the operating state is abnormal, it is necessary to adopt a charging strategy different from that of the normal operating state. For example, a charging strategy such as increasing the charging time or shortening the charging cycle can be adopted to enable the second battery to continue to stably power the control device. Therefore, by determining the charging strategy corresponding to the operating state, it is possible to determine the appropriate charging strategy according to different operating states, thereby improving the charging accuracy.

[0071] In one embodiment, S130 determines the power replenishment strategy corresponding to the operating state, including:

[0072] Acquire second power information of the second battery, where the second power information indicates the power level of the second battery;

[0073] When the power level indicated by the second power level information is less than the second threshold, a power replenishment strategy corresponding to the operating state is determined.

[0074] In this embodiment, during the process of determining the corresponding charging strategy for the operating state, it is possible that the second battery has sufficient charge and does not require charging. Therefore, it is first necessary to obtain the charge information of the second battery, obtain the second charge information, and determine whether the charge indicated by the second charge information is less than a second threshold, where the second threshold indicates a threshold for determining whether the second battery has sufficient charge. Next, if the charge indicated by the second charge information is not less than the second threshold, it indicates that the charge of the second battery is sufficient and does not require charging. In this case, the charging strategy determined is a no-charge-required strategy. Then, if the charge indicated by the second charge information is less than the second threshold, it indicates that the charge of the second battery is insufficient and requires charging. In this case, the charging strategy corresponding to the operating state can be determined. This avoids the problem of charging when the second battery has sufficient charge, which may lead to overcharging of the second battery and affect its service life, and achieves the effect of accurately charging according to the charge of the second battery.

[0075] In one embodiment, the operating state is a normal state or an abnormal state; S130 determines the power replenishment strategy corresponding to the operating state, which may include:

[0076] When the operating state is normal, determining the charging strategy to be the first charging strategy, where the first charging strategy indicates a method of charging the second battery when the operating state is normal; or

[0077] When the operating state is abnormal, the power replenishment strategy is determined to be the second power replenishment strategy, where the second power replenishment strategy indicates a method of replenishing power for the second battery when the operating state is abnormal.

[0078] The normal state or abnormal state in this embodiment is consistent with the above. The normal state indicates that the CAN network is in sleep mode when the vehicle is turned off, and the abnormal state indicates that the CAN network is still in start mode when the vehicle is turned off. When the operating state is normal, the power replenishment strategy is determined to be the first power replenishment strategy. The first power replenishment strategy indicates a method for replenishing the second battery when the operating state is normal, such as a power replenishment strategy with a charging time of 30 minutes. When the operating state is abnormal, the power replenishment strategy is determined to be the second power replenishment strategy. The second power replenishment strategy indicates a method for replenishing the second battery when the operating state is abnormal, such as a power replenishment strategy with a charging time of 60 minutes. It should be noted that the power replenishment strategy corresponding to the operating state can be pre-set according to needs. Different power replenishment strategies may have different power replenishment times, different power replenishment powers, different power replenishment thresholds, etc., which are not specifically limited here.

[0079] S140: Based on the charging strategy, control the first battery to charge the second battery.

[0080] Specifically, after determining the charging strategy corresponding to the operating state, the first battery can be controlled to charge the second battery based on the charging strategy. Specifically, the charging strategy can be sent to the vehicle-mounted system installed on the vehicle. After receiving the charging strategy, the vehicle-mounted system forwards the charging strategy to the battery management system (BMS), and then the BMS executes the charging strategy to control the first battery to charge the second battery.

[0081] like Figure 2 As shown, in one embodiment, S140 controls the first battery to charge the second battery based on the charging strategy, including:

[0082] S1410: Determine a first charging time of a first charging strategy, where the first charging time indicates a duration for charging the second battery using the first charging strategy.

[0083] S1411: Control the first battery to charge the second battery;

[0084] S1412: When the time for the first battery to recharge the second battery reaches a first recharging time, obtaining first recharging power information of the second battery, where the first recharging power information indicates the power of the second battery after being recharged for the first recharging time;

[0085] S1413: When the power level indicated by the first recharge power level information is less than a second threshold, control the first battery to recharge the second battery;

[0086] S1414: Outputting first power-recharging completion information, where the power-recharging completion information includes first re-power-recharging information, where the first re-power-recharging information indicates a frequency of re-powering within a preset time.

[0087] In this embodiment, based on the charging strategy, when controlling the first battery to charge the second battery, first, a first charging time of the first charging strategy is determined; then, the first battery is controlled to charge the second battery, and when the time for the first battery to charge the second battery reaches the first charging time, first charging power information of the second battery is obtained; then, it is determined whether the power of the second battery after being charged for the first charging time indicated by the first charging power information is less than a second threshold value, and the second threshold value indicates whether the power threshold value of the second battery is sufficient; then, when the power indicated by the first charging power information is less than the second threshold value, it means that the current power of the second battery has not reached the sufficient power threshold value, and at this time, the first battery is controlled to charge the second battery again. Recharge, wherein the duration of the second recharge may be the same as or different from the first recharge time. It should be noted that the second recharge here refers to the second recharge step relative to the previous recharge step; and the first recharge completion information is output accordingly, and the recharge completion information includes the first recharge information, and the first recharge information indicates the frequency of recharge within a preset time, such as the frequency of recharge within 1 week, the frequency of recharge within 15 days, etc.; and when the power indicated by the first recharge power information is not less than the second threshold, it indicates that the current power of the second battery has reached the sufficient power threshold and no further recharge is needed, then the first recharge completion information is directly output, and it should be noted that the first recharge completion information output at this time still includes the first recharge information.

[0088] like Figure 3 As shown, in one embodiment, the method may further include:

[0089] S1415: Determine the first re-powering information included in the first power-up completion information;

[0090] S1416: Outputting first abnormality information of the second battery when the frequency indicated by the first recharging information is higher than the first preset frequency; or

[0091] S1417: When the frequency indicated by the first recharging information is not higher than the first preset frequency, output first normal information of the second battery.

[0092] In this embodiment, the status of the second battery is determined based on the first recharge completion message. Because a battery with an abnormality has a weak charge capacity, meaning it loses power quickly and requires frequent recharges, the presence of an abnormality in the second battery can be determined by determining whether the frequency indicated by the first recharge completion message exceeds a first preset frequency. The first preset frequency represents a preset threshold for the frequency of abnormality in the second battery, such as 10 times a month or 15 times a month. If the frequency indicated by the first recharge completion message exceeds the first preset frequency, it indicates that the second battery has been recharged frequently, indicating a battery abnormality. In this case, first abnormality information for the second battery is output, indicating that the second battery is abnormal. If the frequency indicated by the first recharge completion message does not exceed the first preset frequency, it indicates that the second battery has been recharged infrequently, indicating that there is no battery abnormality. In this case, first normal information for the second battery is output, indicating that the second battery is normal. Thus, the first recharge completion message in the first recharge completion message serves to determine whether the second battery is abnormal, thereby effectively detecting abnormalities in the second battery during the recharge process.

[0093] like Figure 4 As shown, in one embodiment, S140 controls the first battery to charge the second battery based on the charging strategy, including:

[0094] S1420: Determine a second charging time of the second charging strategy, where the second charging time indicates a duration for charging the second battery using the second charging strategy.

[0095] S1421: Control the first battery to charge the second battery;

[0096] S1422: When the time for the first battery to recharge the second battery reaches a second recharging time, obtaining second recharged power information of the second battery, where the second recharged power information indicates the power of the second battery after being recharged for the second recharging time;

[0097] S1423: When the power level indicated by the second recharge power level information is lower than a second threshold, control the first battery to recharge the second battery;

[0098] S1424: Output second power replenishment completion information, which includes second re-power replenishment information and operation abnormality frequency information. The second re-power replenishment information indicates the frequency of re-power replenishment within the preset time, and the operation abnormality frequency information indicates the frequency of abnormal operation within the preset time.

[0099] In this embodiment, based on the charging strategy, when controlling the first battery to charge the second battery, the charging time of the second charging strategy is first determined to obtain the second charging time, wherein the second charging time is greater than the first charging time in the aforementioned embodiment. In this way, by increasing the charging time, the problem of the second battery being quickly depleted due to the increased power consumption of the CAN network in the ignition off state is solved, and the effect of replenishing more power for the second battery in the case of increased power consumption is achieved; then, the first battery is controlled to charge the second battery, and when the time for the first battery to charge the second battery reaches the second charging time, second charging power information of the second battery is obtained; then, it is determined whether the power of the second battery after being charged for the second charging time indicated by the second charging power information is less than a second threshold, the second threshold indicating a power threshold of whether the second battery has sufficient power; then, when the power indicated by the second charging power information is less than the second threshold, it means that the current power of the second battery is insufficient and needs to be further charged, and in this case, the first battery is controlled to charge the second battery. A first battery recharges a second battery, where the duration of the recharging may be the same as or different from the second charging time. It should be noted that the recharging here is a second charging step relative to the previous charging step; and second charging completion information is output accordingly. The charging completion information includes second recharging information and abnormal operation frequency information. The second recharging information indicates the frequency of recharging within a preset time, for example, 10 rechargings within a week, 20 rechargings within 15 days, etc. The abnormal operation frequency information indicates the frequency of abnormal operation within a preset time, for example, 5 abnormal states within a week, 8 abnormal states within 15 days, etc. If the power level indicated by the second recharging power level information is not less than a second threshold, it indicates that the power level of the second battery has reached the normal operating power level threshold and no further charging is required. In this case, the second charging completion information output at this time still includes the second recharging information and the abnormal operation frequency information.

[0100] like Figure 5 As shown, in one embodiment, the method further includes:

[0101] S1425: Determine the second re-powering information and the abnormal operation frequency information included in the second power-up completion information;

[0102] S1426: Outputting second abnormality information of the second battery when the frequency indicated by the second recharging information is higher than the second preset frequency, or when the frequency indicated by the abnormal operation frequency information is higher than the third preset frequency; or

[0103] S1427: Output second normal information of the second battery when the frequency indicated by the second recharging information is not higher than the second preset frequency and the frequency indicated by the abnormal operation frequency information is not higher than the third preset frequency.

[0104] In this embodiment, the status of the second battery is determined by the second recharge completion information. Because the battery has a weak power storage capacity when it is abnormal, that is, it loses power quickly and needs to be recharged frequently, so it can be determined whether the second battery is abnormal by determining whether the frequency represented by the second recharge information is higher than the second preset frequency, where the second preset frequency represents a preset frequency threshold for the second battery to be abnormal, such as 10 times a month, 15 times a month, etc.; In addition, the abnormal operation of the vehicle's control network will affect the vehicle's battery life. Since the vehicle's control network may have only one abnormal operation state due to individual special reasons, and no abnormal state will appear subsequently, the vehicle's control network can be ruled out as abnormal at this time; determine whether the frequency represented by the abnormal operation frequency information is higher than the third preset frequency, where the third preset frequency represents the frequency of determining that the vehicle's control network is abnormal, such as the vehicle's control network's operation state has a large abnormality in a month. If the vehicle is in an abnormal state 10 times, it is confirmed that there is an abnormality in the vehicle's control network, so as to judge whether there is an abnormality in the vehicle's control network; when the frequency indicated by the second re-charging information is higher than the second preset frequency, it means that the second battery is currently re-charged a large number of times and there is a battery abnormality, or when the frequency indicated by the operation abnormality frequency information is higher than the third preset frequency, it means that there is an abnormality in the current vehicle's control network, and the vehicle's control network needs to be inspected or maintained, etc. At this time, the second abnormality information of the second battery is output. The second abnormality information of the second battery may include at least one warning information of the second battery warning information or the control network warning information, wherein the second battery warning information indicates that the second battery has weak power storage capacity, and the control network warning information indicates that the vehicle's control network has an operation abnormality and needs to be inspected or maintained.
