Background Art

[0003] With the advent of the era of intelligentization and informatization, the power demand has increased significantly. To reduce pressures such as environmental pollution and energy consumption, household energy storage systems are gradually being introduced into many households.

[0004] In the existing technology, at home, solar power generation panels can be used to supply power to various household appliances, and energy storage technology can be used to store the power generated by photovoltaics in a battery pack, so that the battery pack can supply power when needed. In actual applications, new energy vehicles can also be connected to a household energy storage system for charging. However, due to the limited output power of the household energy storage system, usually, it cannot meet the needs of rapid charging of new energy vehicles. Therefore, when a new energy vehicle is connected to a household energy storage system for charging, a mismatch between demand and supply may occur, making it easy for charging failures or a decrease in charging efficiency of new energy vehicles to occur, which may affect the normal use of new energy vehicles. Therefore, how to flexibly utilize a household energy storage system for charging new energy vehicles has become one of the technical problems that need to be solved urgently.

[0013] To enable those skilled in the art to better understand the technical concept of this application, the technical concept of the embodiments of this application will be described clearly and comprehensively below with reference to the drawings of the embodiments of this application.

[0014] In the existing technology, at home, solar power generation panels may be used to supply power to various household appliances, and energy storage technology may be used to store the power generated by photovoltaics in a battery pack, so that the battery pack can supply power when needed. In an existing household energy storage system, a new energy vehicle can be connected to the household energy storage system for charging. However, the output power of a household energy storage system usually cannot meet the needs of rapid charging of new energy vehicles, there may be a mismatch between demand and supply, and it is difficult to effectively complete the charging task. Therefore, the technical problem to be solved by this application is how to flexibly utilize a household energy storage system for charging new energy vehicles.

[0015] Referring to FIG. 1, FIG. 1 is a schematic diagram showing the structure of a household energy management system according to an embodiment of the present application. As shown in FIG. 1, the household energy management system 10 may include a utility control system 11, a household energy storage system 12, and a terminal device 13. The household energy storage system 12 may include a photovoltaic panel group 121, a smart inverter 122, and a battery pack 123. The smart inverter 122 can be respectively connected to the photovoltaic panel group 121, the battery pack 123, the utility control system 11, and the terminal device 13. The battery pack 123 may include a plurality of single cells connected in parallel. The terminal device 13 can be connected to the smart inverter 122.

[0016] The smart inverter 122 can be connected to the battery pack 123 in the household energy storage system 12, and the battery pack 123 is used to charge a new energy vehicle. The smart inverter 122 can also be connected to the utility control system 11, and the utility control system 11 is used to charge a target vehicle.

[0017] Optionally, the smart inverter 122 can obtain the charging data for each charge when completing the charging of the new energy vehicle using the utility power control system 11.

[0018] Optionally, the smart inverter 122 can establish a communication connection with the household energy storage system 12, and obtain the remaining power of the battery pack 123 in the household energy storage system 12, the historical power supply amount within each period of the battery pack 123, and the charging data for each charge when completing the charging of the new energy vehicle using the battery pack 123 in the household energy storage system 12.

[0019] Optionally, the user can establish a communication connection with the new energy vehicle using the terminal device 13. The terminal device 13 can obtain and store vehicle-related information such as the remaining power, power consumption, and charging data of the new energy vehicle. The smart inverter 122 can obtain the vehicle-related information stored in the terminal device 13 through the terminal device 13, and can also display the charging mode to the user and send a prompt message to the user through the terminal device 13.

[0020] In the embodiments of the present application, the terminal device 13 can be any form of electronic device that can establish a communication connection with the new energy vehicle. Examples include smart phones, portable notebook computers, desktop computers, self-service terminals, in-vehicle terminals, etc. In the present application, there is no particular limitation on the implementation form of the terminal device.

[0021] Referring to FIG. 2, FIG. 2 is a schematic diagram showing the structure of another household energy management system according to the embodiments of the present application. As shown in FIG. 2, the smart inverter 122 can include a controller 124 and an inverter 125.

[0022] Selectively, the controller 124 can control the inverter 125 to charge the new energy vehicle using the battery pack 123 and / or the streetcar control system 11.

[0023] Here, inverter 125 is a converter that can convert DC power (from a battery or storage battery) into AC power (generally a sine wave of 220V, 50Hz) having a fixed frequency and fixed voltage, or a variable frequency and variable voltage.

[0024] In embodiments of this application, the controller 124 may be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component. The embodiments of this application do not particularly limit the product form of the controller 124.

[0025] Referring to Figure 3, Figure 3 is a flowchart of a charging control method according to an embodiment of the present application. This charging control method can be applied to the smart inverter 122 of the home energy management system 10 shown in Figure 1. As shown in Figure 3, this method may include the following steps.

[0026] S301: If a charging event corresponding to the target vehicle is detected, obtain the reference charging frequency at which the target vehicle was charged using the battery pack.

[0027] In some executable embodiments, when the smart inverter 122 detects a charging event corresponding to the target vehicle, it can obtain a reference charging frequency in which the target vehicle was charged using the battery pack. This reference charging frequency may be used to indicate how often an event occurs in which the smart inverter 122 charges the target vehicle using only the battery pack 123 before a charging event corresponding to the target vehicle occurs.

[0028] In an optional embodiment, the smart inverter 122 can obtain a first historical number of times the target vehicle completed charging within a preset period prior to a target charging time in which a charging event occurred, and a second historical number of times the target vehicle completed charging with the battery pack 123 within a preset period prior to the target charging time. The smart inverter 122 can then determine a reference charging frequency for charging the target vehicle using the battery pack 123, based on the first historical number of times the target vehicle completed charging within a preset period prior to the target charging time and the second historical number of times the target vehicle completed charging with the battery pack 123 within a preset period. The preset period may be predefined, preconfigured, or entered by an administrator. For example, the preset period may be 10 days or 30 days.

[0029] The target vehicle is set to charge earlier than the target charging time. period The first historical number of completed charging cycles may include the number of times the target vehicle is fully charged using the battery pack 123, the number of times the target vehicle is fully charged using the streetcar control system 11, and the number of times the target vehicle is fully charged using both the battery pack 123 and the streetcar control system 11. The process of fully charging the target vehicle includes, but is not limited to, the target vehicle being fully charged.

[0030] Selectively, the reference charging frequency for charging the target vehicle using the battery pack 123 is the ratio of the second historical charging count in which the target vehicle completed charging with the battery pack 123 within a preset period to the first historical charging count in which the target vehicle completed charging within a preset period prior to the target charging time. For example, suppose the second historical charging count in which the target vehicle completed charging with the battery pack 123 within a preset period prior to the target charging time in which a charging event occurs is 5, and the first historical charging count in which the target vehicle completed charging within a preset period prior to the target charging time is 10. Based on the first historical charging count of 10 and the second historical charging count of 5, the smart inverter 122 determines the reference charging frequency for charging the target vehicle using the battery pack 123 to be 0.5.

[0031] Selectively, the smart inverter 122 can obtain a first historical number of charging cycles in which the target vehicle completed charging within a set of preset periods prior to the target charging time, and a second historical number of charging cycles in which the target vehicle completed charging using the battery pack 123 within a set of preset periods prior to the target charging time. Next, the smart inverter 122 can determine the intermediate reference charging frequency in which the target vehicle was charged using the battery pack 123 based on the first and second historical charging cycles corresponding to each of the set of preset periods, and further calculate the average of the intermediate reference charging frequencies corresponding to each of the set of preset periods to determine the reference charging frequency in which the target vehicle was charged using the battery pack 123.

[0032] S302: If it is determined that the reference charging frequency is less than or equal to the first preset frequency, and if it is detected that the charging port connected to the target vehicle is a fast charging port, the streetcar control system is used to charge the target vehicle in fast charging mode.

[0033] In some viable embodiments, the smart inverter 122, upon determining that the reference charging frequency is less than or equal to a first preset frequency, can utilize the streetcar control system to charge the target vehicle in fast-charging mode if it detects that the charging port connected to the target vehicle is a fast-charging port. The first preset frequency is a frequency threshold, preset through big data analysis, where the user's sensitivity to charging costs is low.

[0034] The first preset frequency value is relatively small. If the smart inverter 122 determines that the reference charging frequency is less than or equal to the first preset frequency, it may mean that the user rarely uses the battery pack 123 in the home energy storage system 12 to charge the target vehicle. In this case, the smart inverter 122 can directly charge the target vehicle using the tram control system 11. When charging the target vehicle using the tram control system 11, if the charging port connected to the target vehicle is a fast-charging port, the fast-charging port can meet the target vehicle's fast-charging needs, and the target vehicle will be charged in fast-charging mode. If the charging port connected to the target vehicle is a non-fast-charging port, the target vehicle will be charged in non-fast-charging mode. Also, when charging the target vehicle using the tram control system 11, the user needs to make the corresponding payment according to the tram charge standards in order to complete the charging.

[0035] Selectively, if the smart inverter 122 determines that the reference charging frequency is less than or equal to a first preset frequency, it can send an identity identification message to the target vehicle's charging cable to identify the cable information of the target vehicle's charging cable. If the target vehicle's charging cable is a fast charging cable, upon receiving the identity identification message, the target vehicle's charging cable can generate a response message and send it to the smart inverter 122. Furthermore, if the smart inverter 122 determines that it has received the response message sent by the target vehicle's charging cable, it can determine that the charging cable is a fast charging cable, that is, it can determine that the charging port connected to the target vehicle is a fast charging port.

[0036] Furthermore, if the smart inverter 122 determines that the charging port connected to the target vehicle is a fast charging port, it can use the streetcar control system 11 to charge the target vehicle in fast charging mode.

[0037] S303: If it is detected that the charging port connected to the target vehicle is a non-fast charging port, a fast charging prompt message is output via the terminal device to inform the user to use a fast charging port for charging.

[0038] In some executable embodiments, when the smart inverter 122 detects that the charging port connected to the target vehicle is a non-fast charging port, it outputs a fast charging prompt message via the terminal device 13 to alert the user to use a fast charging port for charging.

[0039] Selectively referring to Figure 4, Figure 4 is a schematic diagram showing the interface display of a fast-charging prompt message according to an embodiment of the present application. As shown in Figure 4, when the smart inverter 122 detects that the charging port connected to the target vehicle is a non-fast-charging port, it can output a fast-charging prompt message via the terminal device 13. The fast-charging prompt message may be "Please change the charging port to a fast-charging port" to alert the user to use a fast-charging port for charging.

[0040] S304: When it is detected that the charging port connected to the target vehicle has been upgraded from a non-fast charging port to a fast charging port, the streetcar control system is used to charge the target vehicle in fast charging mode.

[0041] In some viable embodiments, the smart inverter 122 can output a fast-charging prompt message via the terminal device 13 and then detect again whether the charging port connected to the target vehicle is a fast-charging port. When the smart inverter 122 detects that the charging port connected to the target vehicle has been updated from a non-fast-charging port to a fast-charging port, it can use the streetcar control system 11 to charge the target vehicle in fast-charging mode.

[0042] S305: If it is detected that the charging port connected to the target vehicle is still a non-fast charging port, the streetcar control system is used to charge the target vehicle in non-fast charging mode.

[0043] In some viable embodiments, the smart inverter 122 can, after outputting a fast-charging prompt message via the terminal device 13, again detect whether the charging port connected to the target vehicle is a fast-charging port. If the smart inverter 122 detects that the charging port connected to the target vehicle is still a non-fast-charging port, it can use the streetcar control system 11 to charge the target vehicle in non-fast-charging mode.

[0044] S306: If it is determined that the target vehicle's reference charging frequency is greater than the first preset frequency and less than or equal to the second preset frequency, the target charging mode intended by the user is obtained via the terminal device.

[0045] In some viable embodiments, the smart inverter 122 can obtain the user's intended target charging mode via the terminal device 13 if it determines that the target vehicle's reference charging frequency is greater than a first preset frequency and less than or equal to a second preset frequency. The second preset frequency is a frequency threshold, preset through big data analysis, that reflects the user's high sensitivity to charging costs. The target charging mode is used to indicate the charging control mode in which the smart inverter 122 charges the target vehicle.

[0046] Furthermore, if the target vehicle's reference charging frequency is greater than the first preset frequency and less than or equal to the second preset frequency, it may mean that the user charges the target vehicle relatively frequently using the battery pack 123 in the home energy storage system 12, and also relatively frequently using the streetcar control system 11. Therefore, after it is determined that the target vehicle's reference charging frequency is greater than the first preset frequency and less than or equal to the second preset frequency, the charging cost and charging duration of the charging mode are displayed to the user, allowing the user to determine their intended target charging mode.

[0047] Selectively, the target charging mode may be any of the following: a first charging mode that charges the target vehicle using the battery pack 123; a second charging mode that charges the target vehicle using the streetcar control system 11; and a third charging mode that charges the target vehicle using both the battery pack 123 and the streetcar control system 11.

[0048] In selectable embodiments, the smart inverter 122 can display a plurality of selectable charging modes to the user via the terminal device 13 if it determines that the target vehicle's reference charging frequency is greater than a first preset frequency and less than or equal to a second preset frequency. The plurality of selectable charging modes may include at least a first charging mode that charges the target vehicle using the battery pack 123, a second charging mode that charges the target vehicle using the streetcar control system 11, and a third charging mode that charges the target vehicle using both the battery pack 123 and the streetcar control system 11.

[0049] Specifically, referring to Figure 5, Figure 5 is a schematic diagram showing the interface display of the charging modes according to the embodiment of this application. As shown in Figure 5, the terminal device 13 can display the three selectable charging modes to the user, allowing the user to select the target charging mode they intend.

[0050] Selectively referring to Figure 6, which is a schematic diagram showing an interface display for another charging mode according to an embodiment of the present application. The smart inverter 122 can obtain a first current remaining energy of the target vehicle and a second current remaining energy of the battery pack 123, and can determine the reference charging period and reference charging cost corresponding to the first charging mode, the second charging mode, and the third charging mode, respectively, based on the first current remaining energy of the target vehicle, the second current remaining energy of the battery pack 123, and the streetcar fare criteria. As shown in Figure 6, the terminal device 13 can display to the user three selectable charging modes and the reference charging period and reference charging cost corresponding to each of the three selectable charging modes, allowing the user to select the target charging mode they intend.

[0051] Furthermore, when the smart inverter 122 detects a charging mode selection instruction input by the user for one of several selectable charging modes, it can determine the target charging mode intended by the user from among the multiple selectable charging modes according to the charging mode selection instruction.

[0052] S307: Charge the target vehicle in target charging mode.

[0053] In some viable embodiments, the smart inverter 122 can, after obtaining the user's intended target charging mode via the terminal device 13, charge the target vehicle in the target charging mode.

[0054] In an optional embodiment, if the target charging mode is the third charging mode, the smart inverter 122 can obtain a first current remaining energy of the target vehicle at the target charging time when the charging event occurs, a second current remaining energy of the battery pack 123 at the target charging time, and multiple historical power supply amounts of the battery pack 123 generated within multiple historical periods corresponding to the target charging time. By performing statistical analysis on the multiple historical power supply amounts, the smart inverter 122 can predict and obtain a reference power supply amount of the battery pack 123 within the current period in which the target charging time is located. Next, the smart inverter 122 can determine the target energy amount of the target vehicle based on a first preset machine learning model, the first current remaining energy amount, the second current remaining energy amount, and the reference power supply amount. Furthermore, the smart inverter 122 charges the target vehicle using the battery pack 123 and simultaneously detects whether the remaining energy amount of the target vehicle is equal to the target energy amount. When the smart inverter 122 determines that the remaining power of the target vehicle reaches the target power level, it stops charging the target vehicle using the battery pack 123 and starts charging the target vehicle using the streetcar control system 11.

[0055] The first preset machine learning model may be a converged machine learning model obtained by training the model using a large amount of sample data. Each of these multiple sample data may include the remaining power of the target vehicle corresponding to each charging event of the target vehicle, the remaining power of the battery pack 123 at the target charging time in which each charging event occurs, and the historical power supply amount of the battery pack 123 within the first period in which the target charging time in which each charging event occurs is located. Each of the above multiple sample data may correspond to the target power of one target vehicle.

[0056] The period may be a predefined and pre-configured set of time zones, or it may be a set of time zones obtained by the administrator by dividing the 24 hours of a day according to the actual situation. The multiple historical periods corresponding to the target charging time here may be one of the above multiple time zones corresponding to each day prior to the target charging time. The target charging time is located 1 The period can be the current period among multiple time zones in which the target charging time at which the charging event occurs is located. For example, a 24-hour day can be divided into 24 time zones such as 7:00-8:00, 8:00-9:00, 9:00-10:00, etc. Alternatively, a 24-hour day can be divided into 12 time zones such as 7:30-9:30, 9:30-11:30, 11:30-13:30, etc. After determining the target charging time at which the charging event occurs, multiple historical periods corresponding to the target charging time can be determined from the above multiple periods based on the target charging time. For example, if we assume that the target charging time at which the charging event occurs is 8:30, then the historical period corresponding to the target charging time of 8:30 can be determined to be 8:00-9:00.

[0057] Specifically, when the smart inverter 122 detects a charging event corresponding to a target vehicle, it can determine multiple historical periods corresponding to the target charging time at which the charging event occurs. Next, the smart inverter 122 obtains multiple historical power supply amounts of the battery pack 123 generated within multiple historical periods within a preset number of days prior to the target charging time. Furthermore, it performs statistical analysis on the multiple historical power supply amounts generated within multiple historical periods within a preset number of days prior to the target charging time, and calculates an average for one or more historical power supply amounts that are greater than a preset threshold to obtain a reference power supply amount of the battery pack 123 in the current period at which the target charging time is located. By determining one or more historical power supply amounts that are greater than a preset threshold, the smart inverter 122 can exclude low historical power supply amounts due to special circumstances such as going out, and avoid using them as a basis for calculating the reference power supply amount, thereby preventing them from affecting the calculation of the reference power supply amount.

[0058] For example, before the target charging time 1 Within 0 days history Assume that the historical power supply amounts of battery pack 123 corresponding to each period are 2kWh, 1kWh, 2kWh, 0.5kWh, 1kWh, 1kWh, 2kWh, 0.3kWh, 1kWh, and 2kWh, respectively. Assume that the preset threshold is 0.8kWh. The smart inverter 122 can obtain 10 historical power supply amounts for 10 historical periods corresponding to the target charging time within a preset number of days prior to the target charging time, and perform statistical analysis on these 10 historical power supply amounts. Next, the smart inverter 122 can compare these 10 historical power supply amounts with the preset threshold and average the historical power supply amounts greater than the preset threshold. Specifically, the smart inverter 122 can calculate the historical power supply amounts of 8 By averaging the values ​​of 2kWh, 1kWh, 2kWh, 1kWh, 1kWh, 1kWh, 2kWh, 1kWh, and 2kWh, the reference power supply of battery pack 123 during the current period in which the target charging time is located can be determined to be 1.5kWh.

[0059] S308: If it is determined that the target vehicle's reference charging frequency is greater than the second preset frequency, the battery pack is used to charge the target vehicle.

[0060] In some viable embodiments, the smart inverter 122 can use the battery pack 123 to charge the target vehicle if it is determined that the target vehicle's reference charging frequency is greater than a second preset frequency.

[0061] Furthermore, if the target vehicle's reference charging frequency is greater than the second preset frequency, it may mean that the user frequently uses the battery pack 123 of the home energy storage system 12 to charge the target vehicle. Therefore, after it is determined that the target vehicle's reference charging frequency is greater than the second preset frequency, the battery pack 123 can be preferentially used to charge the target vehicle.

[0062] In an optional embodiment, the smart inverter 122 can acquire multiple historical power supply amounts of the battery pack 123 generated within multiple historical periods corresponding to the target charging time in which a charging event occurs, perform statistical analysis on the multiple historical power supply amounts to determine the reference power supply amount of the battery pack in the current period in which the target charging time is located. Furthermore, if the smart inverter 122 determines that the reference power supply amount in the current period is less than or equal to a preset power supply amount, it can use the battery pack 123 to charge the target vehicle.

[0063] The preset power supply amount may be an empirical value, pre-configured, or entered by an administrator. The preset power supply amount is compared with the reference power supply amount for the current period to determine whether the battery pack 123 is at its peak power supply during the current period, and further, whether the battery pack 123 is used to charge the target vehicle during the current period. For example, if the reference power supply amount for the current period is less than or equal to the preset power supply amount, it can be determined that the battery pack 123 is not at its peak power supply during the current period, and the battery pack 123 can be used to charge the target vehicle during the current period. If the reference power supply amount for the current period is greater than the preset power supply amount, it can be determined that the battery pack 123 is at its peak power supply during the current period, and after the current period has elapsed, the battery pack 123 can be used to charge the target vehicle, or the battery pack 123 can be used to charge the target vehicle with limited power during the current period.

[0064] In an optional embodiment, if the smart inverter 122 determines that the reference power supply during the current period is greater than the preset power supply, it can obtain multiple historical power consumptions of the battery pack 123 corresponding to multiple charging processes of the target vehicle completed by the battery pack 123 before the target charging time, and further determine the reference power consumption for each time the target vehicle is charged using the battery pack 123 based on the multiple historical power consumptions. The smart inverter 122 can obtain a second current remaining power of the battery pack 123 at the target charging time. Next, the smart inverter 122 can determine the maximum power supply that the battery pack 123 can provide to the target vehicle during the current period, based on the second preset machine learning model, the reference power consumption, the reference power supply, and the second current remaining power. The maximum power supply may be the maximum amount of power that the battery pack 123 can provide to the target vehicle during the current period. Furthermore, the smart inverter 122 determines the target power supply to charge the target vehicle using the battery pack within the current period, based on the reference power supply amount and the maximum charging period, and can charge the target vehicle with the target power supply using the battery pack 123.

[0065] The second preset machine learning model may be a convergent machine learning model obtained by training the model using a large amount of sample data. Each of these multiple sample data sets represents the power consumption for each instance in which the target vehicle is charged using the battery pack 123 during multiple power supply processes for the target vehicle, and the usage of the battery pack 123 within a first period in which the target charging time at which each charging event occurs is located. Rekiden This may include the power supply amount and the remaining power of the battery pack 123 at the target charging time when each charging event occurs. Each of the above sample data may correspond to the maximum amount of power that the battery pack 123 can supply to the target vehicle.

[0066] For example, let's consider a target vehicle with a battery capacity of 30 kWh, before the target charging time... 1 Assume that the historical power consumption of battery packs 123 charging the target vehicle in 0 charge cycles is 25kWh, 20kWh, 24kWh, 22kWh, 18kWh, 20kWh, 24kWh, 16kWh, 20kWh, and 22kWh, respectively. Assume that the reference power supply in the current period is 2kWh. Assume that the second current remaining power of battery pack 123 is 20kWh. Assume that the target charging time is 5:30, and the current period in which the target charging time is located is 5:00-6:00. The smart inverter 122 is before the above target charging time. 1 An average calculation can be performed on the historical power consumption of the battery pack 123 when charging the target vehicle over 0 charging cycles, and the reference power consumption for each charging cycle using the battery pack 123 can be determined to be 21.1 kWh. Next, the smart inverter 122 uses a second preset machine learning model, Lighting Based on a power consumption of 21.1 kW·h, a reference power supply of 2 kW·h, and a second current remaining power of 20 kW, the smart inverter 122 can determine the maximum power supply to charge the target vehicle using the battery pack 123 to be 10 kW·h. Furthermore, based on a target charging time of 5:30 and the current period of 5:00-6:00, the smart inverter 122 can determine the maximum charging time for the target vehicle within the target period to be 0.5 hours. Based on the maximum power supply of 10 kW·h and the maximum charging time of 0.5 hours, the smart inverter 122 can determine the reference power supply that the battery pack 123 can supply to the target vehicle within the maximum charging time to be 5 kW·h. Furthermore, based on the reference power supply of 5 kW·h and the maximum charging time of 0.5 hours, the smart inverter 122 determines the target power supply for charging the target vehicle using the battery pack 123 to be 10 kW, and charges the target vehicle with a target power supply of 10 kW using the battery pack 123.

[0067] In another optional embodiment, the smart inverter 122 can determine the end time of the current period based on the current period if it determines that the reference power supply amount for the current period is greater than the preset power supply amount. Furthermore, if the smart inverter 122 determines that the end time of the current period has arrived, it can use the battery pack 123 to charge the target vehicle.

[0068] For example, let's assume the current period is from 5:30 to 6:30. If the smart inverter 122 determines that the reference power supply amount during the current period is greater than the preset power supply amount, it can determine the end time of the current period to be 6:30 based on the current period of 5:30 to 6:30. Furthermore, if the smart inverter 122 determines that the end time of the current period, 6:30, has arrived, it can use the battery pack 123 to charge the target vehicle.

[0069] Selectively, if the smart inverter 122 determines that the reference power supply amount for the current period is greater than the preset power supply amount, it can determine the end time of the current period based on the current period and send a first prompt message to the user via the terminal device 13 to remind the user not to charge the target vehicle within the current period where the target charging time is located. If the smart inverter 122 determines that the end time of the current period has arrived, it can send a second prompt message to the user via the terminal device 13 to remind the user to start charging the target vehicle using the battery pack 123 and then start charging the target vehicle using the battery pack 123.

[0070] In the embodiments of this application, the smart inverter 122 in the home energy management system 10 can determine the relationship between a reference charging frequency and a first preset frequency, and the relationship between the reference charging frequency and a second preset frequency, when charging a target vehicle using the battery pack 123. This allows for the determination of a charging control strategy for charging the target vehicle, and further, by charging the target vehicle using the battery pack and / or the streetcar control system, the intelligence and comprehensiveness of charging control for new energy vehicles by the home energy management system can be improved, the boundaries of energy management functions can be expanded, and new energy vehicles can be charged flexibly.
