[0059] In order to more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0060] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0061] Figure 1 Figure 1 shows a flowchart of an intelligent charging control method provided by the present invention.

[0062] As Figure 1 shown, the present invention discloses an intelligent charging control method, including:

[0063] S102, obtaining the charging status data of the charging device;

[0064] S104, analyzing according to the charging status data of the charging device, and drawing the first charging current curve of the charging device;

[0065] S106, when there are multiple charging devices charging simultaneously, establish a coordinate axis with the horizontal axis being the charging current and the vertical axis being the time, input the first charging current curves of all the charging devices into the coordinate axis, and accumulate the first charging current curves of all the charging devices based on time to determine the total charging current curve;

[0066] S108, comparing the total charging current curve with the rated current of the power supply line, marking the part where the total charging current curve is greater than the rated current of the power supply line, and determining the first power supply current curve;

[0067] S110, determining the time interval corresponding to the first power supply current curve as the first time interval;

[0068] S112, dividing the first time interval into multiple second time intervals based on a preset time interval;

[0069] S114, adjusting the charging current of each charging device in each second time interval based on the rated current of the power supply line;

[0070] S116. After the analysis of all the second time intervals is completed, determine the second charging current curve of each charging device;

[0071] S118. Adjust the output current of the corresponding intelligent control socket according to the second charging current curve of each charging device.

[0072] According to the embodiments of the present invention, after the charging device is connected to the intelligent control socket, the charging status data of the charging device is obtained through the device identification module of the intelligent control socket, the first charging current curve of the charging device is drawn according to the charging status data of the charging device, and the output current of the corresponding intelligent control socket is adjusted according to the first charging current curve of the charging device, thereby reducing the load of the power supply line. At the same time, the intelligent control socket monitors in real time during use and performs charging protection processing according to the real-time charging parameters. For example, when the battery of the charging device is fully charged, the power supply is automatically cut off; when the charging device reaches the maximum continuous charging time, the power supply is forcibly cut off; when the actual charging current of the charging device is greater than its rated charging current, the power supply is automatically cut off; when the intelligent control socket is overloaded, the power supply is automatically cut off; when the temperature of the intelligent control socket itself reaches the preset warning temperature, the power supply is automatically cut off, etc.

[0073] When multiple intelligent control sockets are used in the same power supply line (such as when multiple intelligent control sockets are configured in an intelligent charging cabinet), since the multiple intelligent control sockets are connected in parallel and the output voltage of each intelligent control socket is equal, the output current of each intelligent control socket is adjusted to charge and adjust the corresponding charging device respectively.

[0074] When there are multiple charging devices charging using the intelligent control socket at the same time, accumulate the first charging current curves of all the charging devices based on time to determine the total charging current curve, that is, the output current curve of the power supply line when all the charging devices charge according to the preset current. Compare the total charging current curve with the rated current of the power supply line to determine whether all the charging devices can charge according to the preset current.

[0075] When the maximum value of the total charging current curve is less than or equal to the rated current of the power supply line, it means that all the charging devices can charge according to the preset current, and the intelligent control socket adjusts the output current according to the first charging current curve of the connected charging device; when the maximum value of the total charging current curve is greater than the rated current of the power supply line, it means that all the charging devices cannot charge according to the preset current. In some cases, the actual charging current of all or some of the charging devices will be less than the preset current, and the power supply line will be in a high-load state, which is prone to power consumption risks. In this case, mark the part of the total charging current curve that is greater than the rated current of the power supply line to determine the first power supply current curve, and there may be one or more first power supply current curves.

[0076] Determine the first time interval corresponding to the first power supply current curve through the coordinate axis where the first power supply current curve is located, and divide the first time interval into multiple second time intervals based on a preset time interval. Among them, the preset time interval is set by those skilled in the art according to actual needs. Then calculate the first average charging current of the total charging current curve within each second time interval, sort all the second time intervals in descending order according to the magnitude of the first average charging current, and preferentially analyze the second time interval with the largest first average current to obtain the charging impact data of each charging device within this second time interval, and calculate the charging weight of each charging device. Compare the charging weight of each charging device with the maximum charging weight among all charging devices to determine the charging adjustment rate of each charging device.

[0077] Sort all charging devices in ascending order according to the magnitude of the charging adjustment rate, preferentially select the charging device with the smallest charging adjustment rate for analysis, multiply the second average charging current of this charging device by the corresponding charging adjustment rate to determine the adjusted second average charging current of this charging device in the current second time interval, so as to update the first average charging current in the current second time interval. Adjust the second average charging of each charging device in turn according to the magnitude of the charging adjustment rate, and update the first average charging current according to the adjusted second average charging current until the adjusted first average charging current is less than the rated current of the power supply line, then end the adjustment of the second average charging current of the charging devices in the current second time interval.

[0078] Update the corresponding first charging current curve and predicted charging end time according to the adjusted second average charging current of the charging device in the current second time interval. At the same time, redraw the total charging current curve based on the updated first charging current curve of each charging device, and determine whether the first power supply current curve has changed. If it has changed, make corresponding adjustments to the first time interval and the second time interval. When the analysis of all second time intervals is completed, determine the final first charging current curve of the charging device as the second charging current curve of this charging device. Adjust the output current of the corresponding intelligent control socket according to the second charging current curve of this charging device.

[0079] In addition, to avoid the impact of calculation errors on actual charging, such as the actual output current of the intelligent control socket being lower than the output current preset by the system according to the charging current curve of the charging device during a certain time period, resulting in the charging device being unable to complete charging by the latest charging end time, etc., a warning time is determined within the third time interval, and this warning time is used as the latest charging end time of the charging device. When the predicted charging end time of the charging device is greater than or equal to the latest charging end time of the device, the device no longer participates in subsequent current adjustments, and the first charging current curve at this time is determined as the second charging current curve of the device.

[0080] Figure 2 The flowchart of the method for drawing the first charging current curve of the charging device provided by the present invention is shown.

[0081] Such as Figure 2 As shown, according to an embodiment of the present invention, by analyzing the charging status data of the charging device, the first charging current curve of the charging device is drawn, including:

[0082] S202, analyzing according to the charging status data of the charging device to determine the device type and charging parameters of the charging device; the charging parameters at least include battery capacity, charging current, charging voltage, and pre-charging power.

[0083] S204, according to the charging parameters of the charging device, combined with the charging preferences set by the user, formulating a charging strategy to generate the first charging current curve of the charging device.

[0084] It should be noted that after the charging device is connected to the intelligent control socket, the charging status data of the charging device is obtained through the device identification module of the intelligent control socket, the device type of the charging device is identified, and multiple charging parameters such as the rated battery capacity, rated charging current, rated charging voltage, and pre-charging power of the charging device are determined. Combined with the charging preferences set by the user (such as fast charging, trickle charging, timed charging, etc.), the charging strategy is dynamically adjusted, and the current change curves in the trickle charging stage, constant current charging stage, and constant voltage charging stage are respectively drawn to determine the first charging current curve of the charging device.

[0085] According to an embodiment of the present invention, it further includes:

[0086] Calculating the first average charging current of each second time interval through the total charging current curve;

[0087] Calculating the second average charging current of each charging device in each second time interval through the first charging current curve of the charging device;

[0088] Sort the multiple second time intervals in descending order according to the magnitude of the first average charging current; when there are second time intervals with the same average power supply, sort them in chronological order.

[0089] It should be noted that the corresponding partial charging current curve is intercepted from the total charging current curve through the second time interval, the average charging current of this partial charging current curve is calculated, and the first average charging current of the second time interval is determined. The second time intervals are sorted in descending order according to the magnitude of the first average charging current, and the charging currents of each charging device within the second time intervals are analyzed and adjusted in sequence according to the sorted order.

[0090] The corresponding partial charging current curve is intercepted from the first charging current curve of the charging device through the second time interval, the average charging current of this partial charging current curve is calculated, and the second average charging current of the current charging device within the second time interval is determined.

[0091] Figure 3 The flowchart of the method for adjusting the charging current of each charging device within the second time interval based on the rated current of the power supply line provided by the present invention is shown.

[0092] As Figure 3 shown, according to the embodiments of the present invention, adjusting the charging current of each charging device within each second time interval based on the rated current of the power supply line includes:

[0093] S302, obtaining the charging influence data of each charging device within the second time interval based on the start time of the second time interval; the charging influence data includes at least the pre-charging power, the expected charging end time, the charging start time, the cumulative charging power and the cumulative charging duration at the start time of the second time interval;

[0094] S304, calculating the charging weight of each charging device according to the charging influence data of each charging device within the second time interval;

[0095] S306, calculating the ratio of the charging weight of each charging device to the maximum charging weight among all charging devices to determine the charging adjustment rate of each charging device;

[0096] S308, sorting the charging devices in ascending order according to the magnitude of the charging adjustment rate, analyzing each charging device in sequence according to the sorting order, multiplying the second average charging current of each charging device by the corresponding charging adjustment rate to determine the adjusted second average charging current of each charging device within the current second time interval;

[0097] S310, updating the adjusted first average charging current of the current second time interval based on the adjusted second average charging current of the charging device within the current second time interval;

[0098] S312: When the adjusted first average charging current is less than the rated current of the power supply line, end the adjustment of the second average charging current of the charging device within the current second time interval;

[0099] S314: Update the corresponding first charging current curve and predicted charging end time according to the adjusted second average charging current of the charging device within the current second time interval.

[0100] It should be noted that first, input the charging influence data of the second time interval into the charging weight calculation formula of the charging device, calculate the charging weight of each charging device within the second time interval, and determine the maximum charging weight among all charging devices. Then, calculate the ratio of the charging weight of each charging device to the maximum charging weight in turn to determine the charging adjustment rate of each charging device. Sort the charging devices in descending order according to the charging adjustment rate, and preferentially select the charging device with the largest charging adjustment rate. Multiply the second average charging current of this charging device in the current second time interval by the charging adjustment rate to determine the adjusted second average charging current of this charging device in the current second time interval. Subtract the second average charging current of this charging device before adjustment in the current second time interval from the adjusted first average charging current in the current second time interval, and then add the adjusted second average charging current to obtain the adjusted first average charging current in the second time interval. Determine whether the adjusted first average charging current in the second time interval is less than the rated current of the power supply line. If so, end the adjustment of the second average charging current of the charging device within the current second time interval and no longer adjust the second average charging current of the subsequent unadjusted charging devices; if not, select the next charging device in the descending order of the charging adjustment rate, adjust its second average charging current, and update the adjusted first average charging current in the second time interval. Repeat the above operations until the adjusted first average charging current in the second time interval is less than the rated current of the power supply line, end the adjustment, and no longer adjust the second average charging current of the remaining charging devices.

[0101] In addition, if after all charging devices are adjusted, the adjusted first average charging current in the second time interval is still not less than the rated current of the power supply line, then calculate the ratio of the charging weight of each charging device to the sum of the charging weights of all charging devices, and multiply this ratio by the rated current of the power supply line to determine the adjusted second average charging current of each charging device.

[0102] Replace the first charging current curve of the charging device in the current second time interval with the corresponding adjusted second average charging current, update the first charging current curve of this charging device, and re-predict the charging end time according to the updated first charging current curve.

[0103] According to an embodiment of the present invention, it further includes that the calculation method of the charging weight of the charging device is expressed by the formula:

[0104]

[0105] Among them, P n(a) is the charging weight of charging device a in the second time interval n, Q 0(a) is the power of charging device a before charging, Q n(a) is the cumulative charging power of charging device a at the start time of the second time interval n, Q max(a) is the rated battery capacity of charging device a, T n(a) is the cumulative charging duration of charging device a at the start time of the second time interval n, t 1(a) is the predicted charging end time of charging device a, t 0(a) is the charging start time of charging device a, and k1, k2, and k3 are all influencing factors of the charging weight.

[0106] It should be noted that the influencing factors k1, k2, and k3 of the charging weight are all set by those skilled in the art according to actual needs.

[0107] According to an embodiment of the present invention, it further includes:

[0108] Determine the predicted charging end time of the charging device as the start time of the corresponding third time interval;

[0109] Determine the expected usage time through the historical charging data of the charging device;

[0110] Set the power of the charging device at the predicted charging end time as the first preset power, and based on the first preset power, perform a charging simulation to determine the simulated charging end time;

[0111] Compare the expected usage time, the simulated charging end time, and the maximum continuous charging time of the charging device, and determine the minimum time as the end time of the third time interval;

[0112] Calculate the warning time through the charging start time of the charging device, the start time and the end time of the third time interval;

[0113] t y =(1 - k y )(t1 - t0)+k y (t2 - t0)+t0;

[0114] Among them, t y is the warning time, t0 is the charging start time of the charging device, t1 is the start time of the third time interval, t2 is the end time of the third time interval, k yIt is the influencing factor of the warning time.

[0115] It should be noted that the historical charging data of the charging device within the system preset time (such as within the recent 30 days) is screened by the device type of the charging device. By analyzing the distribution law of the historical access time of the historical charging data of the charging device, a normal distribution curve is drawn, and the time interval where the mean μ of the normal distribution curve is located is determined. The time interval is in hours, for example, 7-8 o'clock every day is a time interval, 8-9 o'clock is a time interval, and the start time of this time interval is determined as the predicted access time of the current charging device. In addition, when the number of data of the historical charging data of the charging device within the system preset time is less than the system preset number, or the distribution law of the historical access time of the historical charging data of the charging device does not satisfy the normal distribution law, it is defaulted that the charging device does not have a simulated charging end time.

[0116] Set the power of the charging device at the predicted charging end time to the first preset power, and shift the first charging current curve of the charging device to the right. When the first preset power at the predicted charging end time coincides with the first charging current curve, stop the shift, and determine the charging end time corresponding to the shifted first charging current curve as the simulated charging end time.

[0117] The end time of the third time interval is the latest charging end time of the charging device without affecting the normal use of the device. To avoid the impact of calculation errors on actual charging, such as the actual output current of the intelligent control socket being lower than the output current preset by the system according to the charging current curve of the charging device during a certain period, resulting in the charging device being unable to complete charging at the latest charging end time, etc., a warning time is determined within the third time interval, and this warning time is used as the latest charging end time of the charging device.

[0118] Among them, the influencing factor k of the warning time y has a value range of 0-1, the first preset power is less than or equal to the rated battery capacity of the charging device, and the specific values of the influencing factor k y of the warning time and the first preset power are set by those skilled in the art according to actual needs.

[0119] According to the embodiment of the present invention, it further includes:

[0120] When the predicted charging end time of the charging device is greater than or equal to the corresponding warning time, stop adjusting the first charging current curve of the charging device.

[0121] It should be noted that when the predicted charging end time of a charging device after adjustment in a certain second time interval is greater than or equal to the corresponding warning time, the charging device is marked and no longer participates in the subsequent second time interval analysis process, and the first charging current curve of the charging device at this time is determined as the final second charging current curve.

[0122] According to an embodiment of the present invention, it further includes:

[0123] When the charging of a certain charging device ends or a new charging device is added, resulting in a change in the number of charging devices, the output current of the corresponding intelligent control socket is adjusted again according to the first charging current curve of each charging device.

[0124] It should be noted that during the charging process of charging devices through intelligent control sockets, the charging status of each charging device corresponding to the intelligent control socket is detected in real time. When the number of charging devices in the charging state changes (such as when the charging of a certain charging device ends or a new charging device starts charging, etc.), based on the initial first charging current curve of each charging device and the actual power at the current time, an analysis is performed, and the first charging current curve of the charging devices in the charging state is determined again to obtain the total charging current curve. Then, a second time interval is selected, and the first charging current curve of each charging device is adjusted. Finally, the output current of the corresponding intelligent control socket is adjusted according to the finally determined second charging current curve.

[0125] Figure 4 The block diagram of an intelligent charging control system provided by the present invention is shown.

[0126] As Figure 4 shown, a second aspect of the present invention provides an intelligent charging control system, including:

[0127] A data acquisition module for acquiring the charging status data of charging devices;
