Technical Field

[0001] This application relates to the field of charging control technology, and in particular to a charging control method, device, electronic device and medium. Background Technology

[0002] Currently, new energy equipment is becoming increasingly widespread, and the installation and usage rates of power supply equipment are also rising. For example, new energy vehicles are widely used, and charging stations are being added in parks, residential areas, and other locations to facilitate charging for these vehicles. New energy storage devices have specific performance characteristics; different types, specifications, or grades of new energy equipment may exhibit different characteristics. Charging curves can reflect the characteristics of the storage device, demonstrating the real-time power demand of the new energy equipment throughout the charging process.

[0003] However, energy storage devices have a limited lifespan, and their characteristics change during use. This makes it difficult for the initially determined charging curve to reflect the characteristics of the energy storage device, thus rendering the initial charging curve unreliable and leading to significant errors when specifying charging strategies based on the initial charging curve. Summary of the Invention

[0004] This application provides a charging control method, device, electronic device, and medium to adjust the theoretical charging curve to reflect the actual charging characteristics of the target device during charging, so as to accurately predict the real-time power demand of the target device during subsequent charging based on the adjusted charging curve, and guide the formulation of charging plans and arrangements.

[0031] Example 1

[0032] Figure 1 This is a flowchart illustrating a charging control method provided in Embodiment 1 of this application. This embodiment is applicable to situations where the charging curve of a target device is adjusted to predict the power demand of the target device during subsequent charging based on the adjusted charging curve. This method can be executed by a charging control device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0033] S110. Obtain the theoretical charging curve of the target device, and obtain the actual charging curve of the target device during the actual charging process.

[0034] The target device can be any device equipped with an energy storage unit capable of charging. The energy storage unit can be any device capable of storing and providing electrical energy. The type of target device is not limited, and can include, for example, new energy vehicles, electric vehicles, and electric robots. The theoretical charging curve is the charging curve that comes pre-installed with the target device at the factory, and can be generated by technicians based on the characteristics of the energy storage unit at the time of manufacture. The actual charging curve is obtained by the target device during the actual charging process, representing the actual power acquired at different charging stages, reflecting the characteristics of the energy storage unit during the actual charging process.

[0035] In this embodiment, the charging control device can connect to the target device and directly obtain the theoretical charging curve of the target device if the target device has granted permissions. It can also obtain the target device's identifier, such as device model, name, serial number, or registration number, and retrieve the corresponding theoretical charging curve from the database based on the target device's identifier. During the actual charging process of the target device, the actual power acquired by the target device at each charging stage can be obtained from the power supply equipment to determine the actual charging curve of the target device. The actual charging curve reflects the current actual characteristics of the energy storage device.

[0036] S120. Adjust the theoretical charging curve according to the theoretical charging curve, the actual charging curve, and the preset floating range.

[0037] The preset floating range can be determined based on actual conditions, reflecting the allowable deviation range of the actual charging curve from the theoretical charging curve. During actual charging, fluctuations in the power grid, changes in the characteristics of the energy storage device, and external electromagnetic interference can cause fluctuations in the actual charging power of the target device. Power fluctuations within the preset floating range are reasonable and do not mean that the theoretical charging curve is completely unreliable or that the characteristics of the energy storage device have undergone a fundamental change. Accordingly, the preset floating range can be determined based on power grid fluctuations, the characteristics of the target device's energy storage device, the characteristics of the energy storage device management system, and the characteristics of the charger. For example, the preset floating range is directly proportional to the amplitude of power grid fluctuations; the greater the amplitude of power grid fluctuations, the larger the preset floating range, meaning a greater allowable power deviation during the actual charging process. Similarly, the worse the characteristics of the target device's battery, energy storage device management system, and charger, the larger the preset floating range, also meaning a greater allowable power deviation during the actual charging process. The preset floating range corresponding to different stages of the charging curve can be different, and the preset floating range is inversely proportional to the charging power corresponding to that stage. The higher the charging power, the greater the impact on the power grid. Therefore, excessive power deviation is not allowed, as it would cause a greater impact on the grid. Conversely, the lower the charging power, the smaller the impact on the grid. Thus, the conditions can be appropriately relaxed, allowing for a slightly larger power deviation. For example, the relationship between the preset floating range and the charging power is shown in Table 1. The upper preset floating range in Table 1 represents the preset floating range when the actual charging power during the charging process is greater than the charging power at the same progress point in the theoretical charging curve. The lower preset floating range represents the preset floating range when the actual charging power during the charging process is less than the charging power at the same progress point in the theoretical charging curve. Figure 2 As shown, it is reasonable as long as the actual charging curve is between the charging curve under the upper floating preset range limit and the charging curve under the lower floating preset range limit.

[0038] Table 1

[0039] Charging power Preset floating range for upward movement Preset floating range for downward floating 90~120KW 1％ 1％ 60~90KW 1.2％ 1.2％ 30~60KW 1.4％ 1.4％ 0~30KW 1.6％ 1.6％

[0040] In this embodiment, the theoretical charging curve can be compared with the actual charging curve to determine whether the deviation between the actual charging curve and the theoretical charging curve is within a preset floating range, thereby determining whether to adjust the theoretical charging curve and the adjustment strategy to reflect the current actual charging characteristics of the energy storage device.

[0041] S130. The adjusted theoretical charging curve is used as a reference charging curve to predict the real-time power demand of the target device during the entire charging process.

[0042] For example, for target equipment requiring adjustment, the adjusted theoretical charging curve is used as a reference charging curve. This reference curve reflects the actual charging characteristics of the target equipment's energy storage device, allowing for real-time prediction of the target equipment's power demand throughout the subsequent charging process. This understanding of supply and demand enables the development of charging plans and schedules. For target equipment not requiring adjustment, the theoretical charging curve remains the reference. Based on the charging curve, the timing of power peaks during charging of the target equipment and the impact on the power grid can be predicted in advance, allowing for appropriate intervention and regulation.

[0043] The technical solution of this application embodiment obtains the theoretical charging curve of the target device and the actual charging curve of the target device during the actual charging process; adjusts the theoretical charging curve according to the theoretical charging curve, the actual charging curve, and a preset fluctuation range; and uses the adjusted theoretical charging curve as a reference charging curve to predict the real-time power demand of the target device throughout the entire charging process. This solution can adjust the theoretical charging curve in a timely manner based on the comparison between the theoretical and actual charging curves, so that the adjusted reference charging curve can more realistically reflect the power demand characteristics of the target device during charging. Based on the reference charging curve, the subsequent charging process of the target device can be predicted, and subsequent charging arrangements and plans can be formulated to achieve orderly charging.

[0044] Example 2

[0045] Figure 3 This is a flowchart illustrating a charging control method according to Embodiment 2 of this application. This embodiment is an optimization based on the above embodiments; solutions not described in detail in this embodiment are found in the above embodiments. This application is applicable to situations where the target data is video. Figure 3 As shown, the method in this embodiment of the application specifically includes the following steps:

[0046] S210. Obtain the theoretical charging curve of the target device, and obtain the actual charging curve of the target device during the actual charging process.

[0047] S220. Compare the power corresponding to the same charging progress of the theoretical charging curve with that of the actual charging curve.

[0048] For example, both the theoretical charging curve and the actual charging curve represent the correspondence between charging progress and power, such as... Figure 2 As shown, the horizontal axis of the charging curve represents the charging progress, which can also correspond to charging time, while the vertical axis represents the charging power. Each charging progress corresponds to one power level. By comparing the power corresponding to the same charging progress in the theoretical charging curve with that in the actual charging curve, the deviation of the power during the actual charging process from the theoretical power can be determined. In this embodiment, charging progress for which power comparison is required can be extracted at preset intervals; the smaller the preset interval, the higher the precision.

[0049] S230. If the power difference exceeds the preset floating range, the power corresponding to the charging progress in the actual charging curve will be replaced with the power corresponding to the charging progress in the theoretical charging curve.

[0050] For example, the power difference between the actual charging curve and the theoretical charging curve corresponding to the same charging progress can be calculated. If the power difference exceeds a preset fluctuation range, it indicates that the power variation in the actual charging curve is no longer within a reasonable range, but is caused by changes in the inherent characteristics of the energy storage device. Therefore, the theoretical charging curve needs to be adjusted. Specifically, the power corresponding to the charging progress in the actual charging curve is replaced with the power corresponding to the charging progress in the theoretical charging curve. For example, if the power in the actual charging curve corresponding to 30% charging progress is 90kW, and the power in the theoretical charging curve is 89kW, the power difference is 1kW, and the power fluctuation is 1.1%, which is greater than the preset fluctuation range in Table 1. Therefore, the theoretical charging curve needs to be adjusted, that is, the power corresponding to 30% charging progress in the theoretical charging curve is adjusted to 90kW to reflect the current actual characteristics of the energy storage device. If the power in the actual charging curve corresponding to 60% charging progress is 49.5kW, and the power in the theoretical charging curve is 50kW, the power difference is 1kW, and the power fluctuation is 1%, which does not exceed the preset fluctuation range of the corresponding downward fluctuation in Table 1. Therefore, there is no need to adjust the theoretical charging curve.

[0051] In this embodiment of the application, after replacing the power corresponding to the charging progress in the theoretical charging curve with the power corresponding to the charging progress in the actual charging curve, the method further includes:

[0052] A preset number of new actual charging curves are obtained during the charging process of the target device based on the reference charging curve;

[0053] A preset number of new actual charging curves are compared with the power corresponding to the same charging progress of the theoretical charging curve;

[0054] If the power difference does not exceed the preset floating range, the power corresponding to the charging progress in the theoretical charging curve will not be adjusted.

[0055] If the power difference exceeds the upper limit of the preset fluctuation range, the maximum power corresponding to that charging progress in the theoretical charging curve will be replaced by the maximum power in a preset number of new actual charging curves; and / or,

[0056] If the power difference is lower than the preset floating range lower limit, the minimum power corresponding to the charging progress in the theoretical charging curve will be replaced by the minimum power in the preset number of new actual charging curves corresponding to the charging progress.

[0057] For example, after adjusting the theoretical charging curve, to verify the accuracy of the adjustment, a preset number of new actual charging curves can be obtained during the charging process of the target device based on the reference charging curve. These preset number of new actual charging curves are the actual charging curves obtained during a preset number of charging cycles of the target device. The power corresponding to the same charging progress in the preset number of actual charging curves is compared with that in the theoretical charging curve. If the power difference between each of the preset number of actual charging curves and the theoretical charging curve for the same charging progress does not exceed a preset fluctuation range, then the power corresponding to that charging progress in the theoretical charging curve is not adjusted. This is equivalent to restoring the power if the power corresponding to that charging progress in the reference charging curve was adjusted. If the power difference between an actual charging curve and the theoretical charging curve for the same charging progress exceeds the upper limit of the preset fluctuation range, then the maximum power corresponding to that charging progress in the preset number of new actual charging curves is used to replace the power corresponding to that charging progress in the theoretical charging curve. If the power difference between the actual charging curve and the theoretical charging curve at the same charging stage is lower than the preset lower limit of the floating range, then the minimum power corresponding to that charging power in a preset number of new actual charging curves will replace the power corresponding to that charging stage in the theoretical charging curve. The adjustment method in S230 is verified using a preset number of actual charging curves to avoid errors caused by adjusting the theoretical charging curve due to accidental power fluctuations.

[0058] For example, such as Figure 4As shown, at charging progress 1, the power in both the new actual charging curve 1 and the new actual charging curve 2 is greater than the power of the theoretical charging curve. Assuming the power difference exceeds the preset upward fluctuation range, the power corresponding to charging progress 1 in the new actual charging curve 1, which has the highest power, replaces the power corresponding to charging progress 1 in the theoretical charging curve. At charging progress 2, the power in both the new actual charging curve 2 and the new actual charging curve 3 is less than the power of the theoretical charging curve. Assuming the power difference exceeds the preset downward fluctuation range, the power corresponding to charging progress 2 in the new actual charging curve 2, which has the lowest power, replaces the power corresponding to charging progress 2 in the theoretical charging curve.

[0059] S240. The adjusted theoretical charging curve is used as a reference charging curve to predict the real-time power demand of the target device during the entire charging process.

[0060] S250. If the power difference does not exceed the preset floating range, the theoretical charging curve of the target device will not be adjusted.

[0061] This application provides a charging control method that compares the power corresponding to the same charging progress point between the theoretical charging curve and the actual charging curve. If the power difference exceeds a preset fluctuation range, the power corresponding to the charging progress point in the actual charging curve replaces the power corresponding to the charging progress point in the theoretical charging curve. This allows for timely adjustment of the theoretical charging curve to match the actual charging characteristics of the energy storage device. Based on the reference charging curve, the real-time power demand of the target device throughout the entire charging process can be predicted, and an actual charging schedule can be formulated according to the predicted supply and demand. Furthermore, the adjusted reference charging curve reflects the actual power demand, providing an early warning of actual charging consumption and preventing unknown large impacts on the power grid that could lead to grid collapse.

[0062] Example 3

[0063] Figure 5 This is a flowchart of a charging control method provided in Embodiment 3 of this application. This embodiment is an optimization based on the above embodiments. Solutions not described in detail in this embodiment are found in the above embodiments. Figure 5 As shown, the method in this embodiment of the application specifically includes the following steps:

[0064] S310. Obtain the theoretical charging curve of the target device, and obtain the actual charging curve of the target device during the actual charging process.

[0065] S320. Compare the power corresponding to the same charging progress of the theoretical charging curve with that of the actual charging curve.

[0066] S330. If the power difference exceeds the preset floating range, count the number of times the power difference between at least two actual charging curves and the theoretical charging curve at the same charging progress exceeds the preset floating range; wherein, the at least two actual charging curves are obtained during at least two charging processes of the target device.

[0067] In this embodiment of the application, if a power difference exceeding a preset fluctuation range is detected during the comparison of the power corresponding to the same charging progress between the theoretical charging curve and the actual charging curve, in order to verify that the large change in power is continuous rather than accidental, the theoretical charging curve can be further compared with the power corresponding to the charging progress in at least two actual charging curves, and the number of times the power difference exceeds the preset fluctuation range can be counted.

[0068] S340. If the number of times exceeds a preset number of times and the power difference is higher than the upper limit of the preset floating range, then the maximum power corresponding to the charging progress in the theoretical charging curve is replaced by the maximum power in at least two actual charging curves.

[0069] If the number of attempts exceeds the preset limit, it indicates that the significant power change is not accidental but a continuous process, suggesting a change in the fundamental characteristics of the energy storage device. In this case, the theoretical charging curve will be adjusted. If the power difference exceeds the upper limit of the preset fluctuation range, the maximum power corresponding to that charging progress in at least two charging curves will replace the power corresponding to that charging progress in the theoretical charging curve.

[0070] S350. If the number of times exceeds a preset number of times and the power difference is lower than the preset floating range lower limit, then the minimum power corresponding to the charging progress in the theoretical charging curve is replaced by the minimum power in at least two actual charging curves.

[0071] If the number of attempts exceeds the preset limit, it indicates that the significant power change is not accidental but a continuous process, suggesting a change in the fundamental characteristics of the energy storage device. In this case, the theoretical charging curve will be adjusted. If the power difference is lower than the preset lower limit of the fluctuation range, the minimum power value corresponding to that charging progress in at least two charging curves will replace the power value corresponding to that charging progress in the theoretical charging curve.

[0072] S360. The adjusted theoretical charging curve is used as a reference charging curve to predict the real-time power demand of the target device during the entire charging process.

[0073] S370. If the number of times does not exceed the preset number of times, the theoretical charging curve of the target device will not be adjusted.

[0074] For example, if the number of times does not exceed the preset number, it means that the power fluctuation is accidental and not continuous. In this case, the theoretical charging curve will not be adjusted, and the theoretical charging curve will continue to be used as a reference curve to guide subsequent charging arrangements.

[0075] This application provides a charging control method that compares the power corresponding to the same charging progress point between the theoretical charging curve and the actual charging curve. If the power difference exceeds a preset fluctuation range, the method counts the number of times the power difference between the actual charging curve and the theoretical charging curve exceeds the preset fluctuation range during at least two charging processes based on the theoretical charging curve. If the number of times exceeds a preset number and the power difference is higher than the upper limit of the preset fluctuation range, the maximum power corresponding to the charging progress point in at least two actual charging curves replaces the power corresponding to the charging progress point in the theoretical charging curve. If the number of times exceeds a preset number and the power difference is lower than the lower limit of the preset fluctuation range, the minimum power corresponding to the charging progress point in at least two actual charging curves replaces the power corresponding to the charging progress point in the theoretical charging curve. This solution can accurately verify power fluctuations and avoids the problem of erroneous adjustments caused by hasty changes to the theoretical charging curve due to occasional power fluctuations.

[0076] Example 4

[0077] Figure 6 This is a flowchart of a charging control method provided in Embodiment 4 of this application. This embodiment is an optimization based on the above embodiments. Solutions not described in detail in this embodiment are found in the above embodiments. Figure 6 As shown, the method in this embodiment of the application specifically includes the following steps:

[0078] S410. Obtain the theoretical charging curve of the target device, and obtain the actual charging curve of the target device during the actual charging process.

[0079] S420. Adjust the theoretical charging curve according to the theoretical charging curve, the actual charging curve, and the preset floating range.

[0080] S430. Use the adjusted theoretical charging curve as a reference charging curve to predict the real-time power demand of the target device during the entire charging process.

[0081] S440. If the theoretical charging curve of the target device has not been adjusted, then the theoretical charging curve shall be taken as the actual charging curve corresponding to the target device.

[0082] S450. For each charging progress, compare the sum of the real-time demand power corresponding to the charging progress in the actual charging curve of each device to be charged with the power available from the power supply equipment; wherein, the actual charging curve includes the theoretical charging curve or the reference charging curve.

[0083] In this embodiment, the device to be charged is a device that requires a power supply to charge it. If the theoretical charging curve of the device to be charged has been adjusted, the adjusted reference charging curve is used as the actual charging curve corresponding to the device. If the theoretical charging curve has not been adjusted, it is used as the actual charging curve corresponding to the device. The actual charging curve used by each device to be charged during the upcoming charging process is compared with the available power of the power supply to assess the supply and demand of electrical energy. Specifically, the power corresponding to the charging progress in each actual charging curve is summed to represent the sum of the charging power required for each device to be charged to simultaneously reach the specified charging progress. The sum of the power is compared with the available power of the power supply to determine whether the power supply meets the requirement of simultaneously charging each device.

[0084] S460. If the total real-time demand power corresponding to the charging progress exceeds the available power, then the actual charging time of the device to be charged is determined according to the reference charging curve, theoretical charging curve and available power of the device to be charged.

[0085] For example, if the total real-time power demand corresponding to the charging progress exceeds the available power, it means that the power supply equipment is unable to meet the requirement of supplying power to all devices to be charged at the same time. In this case, the charging time of the power supply equipment for each device to be charged can be adaptively determined according to the reference charging curve, theoretical charging curve and available power of the devices to be charged, so as to achieve a balance between power supply and demand.

[0086] In this embodiment of the application, determining the actual charging time of the device to be charged based on the reference charging curve, the theoretical charging curve, and the available power of the device to be charged includes:

[0087] Pre-charging devices are selected from the devices to be charged in ascending order of real-time power demand corresponding to the same charging progress on the actual charging curve.

[0088] If the total real-time power demand of the pre-charging devices is less than or equal to the available power, then it is determined that the devices to be charged will be charged simultaneously.

[0089] For example, assuming that devices are being charged simultaneously, the total real-time power demand of these devices exceeds the power available from the power supply. In this case, some devices are selected for pre-charging. If the total real-time power demand of these pre-charging devices is less than or equal to the power available from the power supply, then the power supply can meet the demand for simultaneous charging of the pre-charging devices, and therefore, they can be charged simultaneously. The method for selecting pre-charging devices is to select them in ascending order of real-time power demand corresponding to the same charging progress in the actual charging curve, in order to charge the maximum number of devices as quickly as possible. The same charging progress can be any charging progress in the actual charging curve, such as the first, second, or third charging progress, etc., and is not limited here.

[0090] In this embodiment of the application, the method further includes:

[0091] A pre-charging device is selected from the devices to be charged based on the handshake connection time between the device to be charged and the power supply device;

[0092] The real-time power demand is determined based on the reference charging curve or theoretical charging curve of the pre-charging device.

[0093] If the total real-time power demand of all pre-charged devices is less than or equal to the available power of the power supply device, then the pre-charged devices are determined to be charged according to the handshake connection time.

[0094] The handshake connection time represents the time it takes for the device to be charged and the power supply to reach an agreement before data transmission. The handshake connection time reflects when the device to be charged requests charging from the power supply. An earlier handshake connection time indicates an earlier request for charging. Pre-charging devices can be selected from the devices requiring charging based on the handshake connection time. Devices with earlier handshake connection times are designated as pre-charging devices. The number of pre-charging devices selected can be determined through calculation, assuming the power supply can meet the simultaneous power supply requirements. The real-time power demand is determined based on the reference charging curve or theoretical charging curve of the pre-charging device. If the theoretical charging curve of the pre-charging device has been adjusted to obtain a reference charging curve, the real-time power demand is determined based on the reference charging curve. If the theoretical charging curve of the pre-charging device has not been adjusted, the real-time power demand is determined based on the theoretical reference curve. Specifically, the sum of real-time power demand corresponding to the same progress in the reference charging curve or theoretical charging curve of the pre-charging device is calculated. If the sum of real-time power demand is less than or equal to the available power of the power supply, the pre-charging device is charged according to the handshake connection time. The above scheme essentially involves charging the devices to be charged on a first-come, first-served basis, provided the power supply equipment meets the requirements. For example, as shown in Table 2, the charging pile is the power supply equipment, the charging pile domain controller is the charging control equipment, and the new energy vehicle is the device to be charged. Based on the handshake connection time between the new energy vehicle and the charging pile domain controller, and provided that power supply and demand are balanced, priority can be given to the new energy vehicle that initiates the handshake connection first.

[0095] Table 2

[0096]

[0097] In addition, priorities can be pre-set for each device waiting to be charged, and the charging order can be determined by a comprehensive evaluation based on priority ranking and first-come, first-served. Furthermore, higher-priority devices can be allowed to schedule charging times, and charging will be performed on a first-come, first-served basis according to the order of scheduled times. For example, VIP vehicles can schedule charging times in advance, such as 09:15, with a 20-minute buffer before and after 09:15, allowing time between 08:45 and 09:35 for arrival at the designated parking space. If the time exceeds this range, the previous reservation is cancelled and a new reservation must be made.

[0098] This application provides a charging control method that, for each charging progress, compares the sum of real-time power demands corresponding to the actual charging progress of each device to be charged with the available power of the power supply equipment. If the sum of real-time power demands corresponding to a charging progress exceeds the available power, the actual charging time of the device to be charged is determined based on the reference charging curve, theoretical charging curve, and available power of the device to be charged. This solution can accurately predict the power demand of the device to be charged during the upcoming charging process based on its actual charging curve, and then determine the actual charging time of the device to be charged by combining this with the available power of the charging equipment. This precisely coordinates the orderly charging of each device to be charged, avoiding the problem of power supply and demand imbalance caused by charging devices without planning, which affects the safety of the charging equipment.
