Devices whose power increase rates exceed the power increase threshold are marked as fast-charging devices; and devices whose power increase rates are lower than the power increase threshold are marked as slow-charging devices.

[0014] In a preferred embodiment, in step S1, when predicting the type of electrical equipment, rules are set to make a judgment and prediction, and the specific rules are as follows:

[0015] Rule 1: When the power supply battery is connected to the power-consuming device, the voltage property of the bus voltage is a DC voltage and the power-consuming device is marked as a fast charging device, then the power-consuming device type is classified as a constant current charging device;

[0016] Rule 2: When the power supply battery is connected to the power-consuming device, the nature of the bus voltage is AC voltage and the power-consuming device is marked as a slow charging device, then the power-consuming device type is classified as a constant voltage charging device;

[0017] The system will classify the electrical equipment that meets the above rules and mark the electrical equipment that does not meet the above rules as pending equipment.

[0018] In a preferred embodiment, in step S2, the system makes a corresponding response process according to the type of the new electrical device, and the specific steps are as follows:

[0019] When the system determines that the new power-consuming device is a constant voltage charging device, the power supply mode is not processed; when the system determines that the new power-consuming device is a constant current charging device, the AC power is converted into DC power through a rectifier to charge the new power-consuming device. The charging information is transmitted to the user end;

[0020] When a new power-consuming device is marked as a pending device, the service life of the new power-consuming device is detected and compared with the service life of devices classified as constant-voltage charging devices in the database. When the service life of the new power-consuming device is lower than the minimum service life of constant-voltage charging devices in the database, the new device is processed as a constant-current charging device and the charging information is transmitted to the user end; otherwise, an option is sent to the user end, and the new device is charged by the user selecting DC voltage or AC voltage.

[0021] In a preferred embodiment, in step S2, the system determines the real voltage property of the electrical equipment through user feedback information. The specific steps are as follows:

[0022] When the system does not process the power supply mode, the charging information is transmitted to the user end. If the user chooses to confirm or the skip time is exceeded without confirmation, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant voltage charging device; otherwise, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant current charging device.

[0023] In a preferred embodiment, in step S2, the system determines the real voltage property of the electrical equipment through user feedback information. The specific steps are as follows:

[0024] When the system does not process the power supply mode, the charging information is transmitted to the user end. If the user chooses to confirm or the skip time has passed without confirming the information, the real voltage property of the bus voltage required by the power-consuming device is judged to be a constant voltage charging device; otherwise, the real voltage property of the bus voltage required by the power-consuming device is judged to be a constant current charging device;

[0025] When the system converts AC power into DC power through a rectifier, the charging information is transmitted to the user end when the new electrical equipment is charged. If the user chooses to confirm or the skip time is exceeded without confirming the information, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant current charging device; otherwise, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant voltage charging device.

[0026] In a preferred embodiment, in step S3, the system selects a period of time as the analysis period, calculates the power consumption adjustment ratio according to the new power-consuming equipment recorded in the database during the analysis period, and adjusts the power increase threshold by the power consumption adjustment ratio to classify and update the power-consuming equipment. The specific steps are as follows:

[0027] Assignment setting: When the predicted voltage property type of the new electrical equipment is consistent with the actual voltage property type of the new electrical equipment, the output result is 1; otherwise, the output result is 0;

[0028] Statistical type deviation: New power-consuming equipment classified into different categories is counted separately, and the ratio of the number of 1s in the output results of new power-consuming equipment in each category to the total number of new power-consuming equipment in the corresponding category is counted. The ratio of constant current deviation to constant voltage deviation is used as the power adjustment ratio;

[0029] Adjust the power increase threshold: Divide the power increase threshold by the power adjustment ratio to obtain the new power increase threshold.

[0030] In a preferred embodiment, in step S4, after the system determines that the new electric device is marked as a pending device, it assigns two preset device attributes to the new electric device, one attribute is that the charging process has a single bus voltage attribute; the other attribute is that the charging process has two bus voltage attributes;

[0031] When the device attribute of the new power-consuming device is a single DC bus voltage property, the device abnormality coefficient is calculated and compared with the preset abnormality threshold. If the device abnormality coefficient of the current device exceeds the abnormality threshold, the charging process of the current device is judged as an abnormal charging process, and the system converts the charging mode of the current device.

[0032] When the device attribute of the new electrical equipment is to have two DC bus voltage properties, the number of charging mode conversions is adjusted by the equipment abnormality coefficient. The average charging time and the average number of conversions are calculated based on the devices with two DC bus voltage properties recorded in the database. The charging time of the current device is divided by the average charging time and the result is multiplied by the average number of conversions to obtain the number of charging mode conversions of the current device. Then, the conversion time is calculated according to the charging time and the number of charging mode conversions of the current device, so as to provide a voltage conversion solution.

BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 The schematic diagram of an adaptive control method based on DC bus voltage of the present invention is shown in FIG. DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention detects the transfer of electrical equipment, records the transfer of electrical equipment of different voltage properties by users, analyzes and predicts the electrical equipment based on the records, determines the voltage property of the electrical equipment each time it is transferred, converts the voltage according to the property and transmits the conversion prompt information to the user end, receives user feedback through the user end, determines whether to convert the charging mode voltage and determines the real voltage property of the electrical equipment after receiving the user end feedback information, records the electrical equipment and voltage properties and obtains the electrical equipment information to update the analysis and prediction of new electrical equipment, screens out electrical equipment that supports multiple charging voltage properties, performs analysis and processing, and provides a voltage conversion solution, thereby improving battery life and environmental safety during battery charging.

[0038] Embodiment, an adaptive control method based on DC bus voltage, such as Figure 1 As shown, the following steps are included:

[0039] Step S1: Detect and record the transfer status of the electrical equipment, mark the electrical equipment according to the recorded information, and predict the type of the electrical equipment according to the mark type;

[0040] Step S2: Determine to provide confirmation information or charging mode options to the user terminal according to the type of the power-consuming device, receive feedback information from the user terminal to determine whether to convert the charging mode voltage and determine the actual voltage property of the power-consuming device;

[0041] Step S3: Record the electrical equipment and voltage properties and calculate the power adjustment ratio, and adjust the prediction results of new electrical equipment that are not recorded according to the power adjustment ratio;

[0042] Step S4: preset the attributes of the new electrical equipment, collect user behavior and equipment status to judge the attributes, determine the attributes of the new electrical equipment according to the judgment results, and provide a voltage conversion solution.

[0043] The specific implementation is as follows:

[0044] In step S1, when detecting the transfer status of the electrical equipment, the user first connects the power supply battery to the electrical equipment. When the electrical equipment is powered on, the system detects the bus voltage of the power supply battery, determines and records the voltage property of the bus voltage, that is, determines whether the bus voltage provided to the electrical equipment is AC voltage or DC voltage. Before charging the electrical equipment, the initial power of the electrical equipment and the time point before charging are recorded. When the electrical equipment is fully charged, the time point is recorded again.

[0045] The increased power is obtained by subtracting the battery capacity of the electrical equipment from the initial power. The time interval is calculated based on the time point of the secondary record. The power increase rate is then calculated based on the time interval and the increased power. The quotient of the increased power and the time interval is taken as the power increase rate. Finally, the power increase rate and the voltage properties of the bus voltage are used to formulate rules for prediction of the type of electrical equipment.

[0046] The system records each time the power supply battery is connected to the user equipment, that is, the voltage properties of the bus voltage and the power increase rate of the corresponding equipment are recorded in the database, and the power increase rate of each device is merged into a power increase rate data set. The power increase threshold is set through the power increase rate data set. The specific steps are as follows:

[0047] The system first calculates the average value of the power-on rate data set, and then randomly extracts data from the power-on rate data set for multiple times to compare with the average value. When the randomly extracted data is larger than the average value, the extracted data and the average value are summed and averaged again, and the new data is used as the new average value for subsequent comparison; when the randomly extracted data is smaller than the average value, the extracted data is put back, and the number of extractions is set to control the threshold size. When the number of random extractions reaches the preset number of extractions, the average value is used as the power-on threshold.

[0048] The increase rate of each device is compared with the power increase threshold, and the device whose power increase rate exceeds the power increase threshold is marked as a fast charging device; the device whose power increase rate is lower than the power increase threshold is marked as a slow charging device.

[0049] When the system predicts the type of electrical equipment, it makes a decision based on the following rules:

[0050] Rule 1: When the power supply battery is connected to the power-consuming device, the voltage property of the bus voltage is a DC voltage and the power-consuming device is marked as a fast charging device, then the power-consuming device type is classified as a constant current charging device.

[0051] Rule 2: When the power supply battery is connected to the power-consuming equipment, the nature of the bus voltage is AC voltage and the power-consuming equipment is marked as a slow charging device, then the power-consuming equipment type is classified as a constant voltage charging device.

[0052] The system will classify the electrical equipment that meets the above rules and mark the electrical equipment that does not meet the above rules as pending equipment.

[0053] It should be noted that constant current charging is faster than constant voltage charging for electrical equipment, and DC power can directly provide energy to the battery, while AC power needs to be converted into DC power by a rectifier for charging, so constant current charging with DC power is more stable.

[0054] In step S2, when the user connects the power supply battery to a new power-consuming device, the system classifies the new power-consuming device by comparing the power increase rate of the new power-consuming device with the power increase threshold. The new power-consuming device is a device that has no record in the database.

[0055] The system responds differently according to the type of new electrical equipment. The specific steps are as follows:

[0056] When the system determines that the new power-consuming device is a constant voltage charging device, the power supply mode is not processed; when the system determines that the new power-consuming device is a constant current charging device, the AC power is converted into DC power through a rectifier to charge the new power-consuming device. The charging information is transmitted to the user end.

[0057] When a new power-consuming device is marked as a pending device, the service life of the new power-consuming device is detected and compared with the service life of devices classified as constant-voltage charging devices in the database. When the service life of the new power-consuming device is lower than the minimum service life of constant-voltage charging devices in the database, the new device is processed as a constant-current charging device and the charging information is transmitted to the user end; otherwise, an option is sent to the user end, and the new device is charged by the user selecting DC voltage or AC voltage.

[0058] The charging information includes the bus voltage properties during the current charging process and the user confirmation information. The user can confirm the charging process or make changes through the user confirmation information and set the skip time. When the time interval of the skip time is reached and the user still has not confirmed the information, the system uses the current charging mode to charge the new electrical device.

[0059] User feedback information includes the options provided by the user when the new power-consuming device is marked as a pending device and the system sends the user an option to use a constant voltage or constant current charging mode, and the confirmation information sent to the user when the system determines that the new power-consuming device is a constant current charging device or a constant voltage charging device, and the user chooses to confirm or change the option.

[0060] The system determines the real voltage properties of electrical equipment through user feedback information. The specific steps are as follows:

[0061] When the system does not process the power supply mode, the charging information is transmitted to the user end. If the user chooses to confirm or the skip time is exceeded without confirmation, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant voltage charging device; otherwise, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant current charging device.

[0062] When the system converts AC power into DC power through a rectifier, the charging information is transmitted to the user end when the new electrical equipment is charged. Similarly, if the user chooses to confirm or fails to confirm the information after the skip time, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant current charging device; otherwise, the actual voltage nature of the bus voltage required by the electrical equipment is judged to be a constant voltage charging device.

[0063] When the system determines that a new electrical device is marked as a pending device, user behavior is continuously collected during the charging project of the new electrical device for subsequent analysis.

[0064] It should be noted that the skip time is used to deal with situations where the user fails to confirm or handle the prompt information in time, resulting in the electrical device not being charged in time. It can be set according to user requirements. For example, the skip time can be set to 5 minutes, etc., and no further analysis will be made here.

[0065] In step S3, if the new electrical equipment is determined to be a constant voltage charging equipment or a constant current charging equipment, the voltage properties of the new electrical equipment and the electrical equipment during charging are saved in the database, and the predicted value of the voltage property of the new electrical equipment and the actual value of the voltage property of the new electrical equipment are compared, that is, whether the predicted type of the voltage property of the new electrical equipment is consistent with the actual type of the voltage property of the new electrical equipment.

[0066] The system selects a period of time as the analysis time, calculates the power adjustment ratio according to the new power-consuming equipment recorded in the database during the analysis time, and adjusts the power increase threshold by the power adjustment ratio to classify and update the power-consuming equipment. The specific steps are as follows:

[0067] Assignment setting: When the predicted type of the voltage property of the new electrical equipment is consistent with the actual type of the voltage property of the new electrical equipment, the output result is 1; otherwise, the output result is 0.

[0068] Statistical type deviation: New power-consuming devices classified into different categories are counted separately, and the ratio of the number of 1s in the output results of new power-consuming devices in each category to the total number of new power-consuming devices in the corresponding category is counted. Taking the two categories in this example as an example, the output result ratios of the two categories of credit power devices are counted separately, and the ratio of the power-consuming devices with an output result of 1 in the constant current charging device to the total number of constant current charging devices is used as the constant current deviation, and the ratio of the power-consuming devices with an output result of 1 in the constant voltage charging device to the total number of constant voltage charging devices is used as the constant voltage deviation, and the ratio of the constant current deviation to the constant voltage deviation is used as the power adjustment ratio.

[0069] Adjust the power increase threshold: Divide the power increase threshold by the power adjustment ratio to obtain the new power increase threshold.

[0070] If new unrecorded electrical equipment appears subsequently, the new power increase threshold value will be used as the judgment standard when classifying the new electrical equipment, and the number of recorded equipment will be set. When the number of new electrical equipment recorded subsequently exceeds the number of recorded equipment, a time interval equal to the analysis time will be selected to readjust the power increase threshold value, thereby marking the new unrecorded electrical equipment and predicting and classifying the new electrical equipment.

[0071] It should be noted that the power adjustment ratio is the ratio of the constant current deviation to the constant voltage deviation. When the constant current deviation exceeds the constant voltage deviation, the accuracy of classifying the new power equipment as constant current charging equipment is higher than the accuracy of classifying the new power equipment as constant voltage charging equipment. However, the higher the power increase threshold, the fewer new power equipment is classified as constant current charging equipment. The power increase threshold can be adjusted downward appropriately to classify more new power equipment as constant current charging equipment. On the contrary, when the constant current deviation is lower than the constant voltage deviation, the power increase threshold can be appropriately adjusted upward to improve the prediction accuracy of the system.

[0072] In step S4, when the system determines that the new power-consuming device is marked as a pending device, two preset device attributes are given to the new power-consuming device, one attribute is that the charging process has a single bus voltage property; the other attribute is that the charging process has two bus voltage properties.

[0073] The system continuously monitors the user end during the charging process of the new power-consuming equipment. If the user does not switch the voltage charging mode, the device attribute of the new power-consuming equipment is judged to be a single DC bus voltage attribute; if the user switches the voltage charging mode during continuous monitoring, the device attribute of the new power-consuming equipment is judged to be a device with two DC bus voltage attributes, that is, it supports both constant current and constant voltage charging modes.

[0074] Before providing a voltage conversion solution, the system detects user behavior and device status. User behavior refers to the number of times the device switches charging modes during the charging process. The device status refers to the charging time of new power-consuming devices. The average charging time of power-consuming devices in the database is used as the denominator, the charging time of the current charging device is recorded and used as the numerator, and the ratio of the numerator to the denominator is used as the device abnormality coefficient.

[0075] When the device attribute of the new electrical equipment is a single DC bus voltage property, the device abnormality coefficient is calculated and compared with the preset abnormality threshold. If the device abnormality coefficient of the current device exceeds the abnormality threshold, the charging process of the current device is judged as an abnormal charging process, and the system converts the charging mode of the current device.

[0076] When the device attribute of the new electrical equipment is to have two DC bus voltage properties, the number of charging mode conversions is adjusted by the device abnormality coefficient. The average charging time and the average number of conversions are calculated based on the devices with two DC bus voltage properties recorded in the database. The charging time of the current device is divided by the average charging time and the resultant is multiplied by the average number of conversions to obtain the number of charging mode conversions of the current device. The conversion time is then calculated based on the charging time and the number of charging mode conversions of the current device to provide a voltage conversion plan. For example, the charging time of the current device is two hours, and the number of charging mode conversions is five. When the current device is charging, the system calculates that it is best to switch the charging mode every 24 minutes and transmits the voltage conversion plan to the user.

[0077] It should be noted that the abnormal threshold can be set according to actual conditions, for example, setting the abnormal threshold to 1.2 is not described here.

The specific steps are as follows: Assignment setting: When the predicted voltage property type of the new electrical equipment is consistent with the actual voltage property type of the new electrical equipment, the output result is 1; otherwise, the output result is 0; Statistical type deviation: New power-consuming equipment classified into different categories is counted separately, and the ratio of the number of 1s in the output results of new power-consuming equipment in each category to the total number of new power-consuming equipment in the corresponding category is counted. The ratio of constant current deviation to constant voltage deviation is used as the power adjustment ratio; Adjust the power increase threshold: Divide the power increase threshold by the power adjustment ratio to obtain the new power increase threshold.
