In practical applications, new energy vehicles can also be connected to a home energy storage system to charge. However, due to limitations on the output power of home energy storage systems, they typically cannot meet the fast charging needs of new energy vehicles. Therefore, when new energy vehicles are connected to a home energy storage system to charge, a mismatch between supply and demand may occur, which may lead to charging failures or reduced charging efficiency of the new energy vehicles, which may affect the normal use of the new energy vehicles.

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

[0014] In existing technology, homes may use solar panels to power various household appliances, and energy storage technology may be used to store the power generated by photovoltaic power generation in a battery pack, allowing the battery pack to provide power when needed. Existing home energy storage systems allow new energy vehicles to be connected to the home energy storage system for charging. However, the output power of the home energy storage system usually cannot meet the fast charging needs of new energy vehicles, which may result in a mismatch between supply and demand, making it difficult to effectively complete the charging task. Therefore, the technical problem solved by this application is how to flexibly utilize home energy storage systems to charge new energy vehicles.

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

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

[0017] Optionally, the smart inverter 122 can obtain charging data for each time when the tram control system 11 is used to complete charging of the new energy vehicle.

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

[0019] Optionally, the user can establish a communication connection with the new energy vehicle using the terminal device 13. The terminal device 13 can acquire 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 acquire the vehicle-related information stored in the terminal device 13 through the terminal device 13, and can display the charging mode to the user and send prompt messages to the user through the terminal device 13.

[0020] In the embodiment of the present application, the terminal device 13 can be any form of electronic device that can establish a communication connection with a new energy vehicle, for example, a smartphone, a portable notebook computer, a desktop computer, a self-service terminal, an in-vehicle terminal, etc. The present application does not place any particular limitation on the implementation form of the terminal device.

[0021] 2, which is a schematic diagram illustrating the structure of another home energy management system according to an embodiment of the present application. As shown in FIG. 2, the smart inverter 122 may include a controller 124 and an inverter 125.

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

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

[0024] In an embodiment of the present 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. In an embodiment of the present application, the product form of the controller 124 is not particularly limited.

[0025] Referring to Fig. 3, Fig. 3 is a flowchart illustrating 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 Fig. 1. As shown in Fig. 3, the method can include the following steps:

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

[0027] In some possible embodiments, when the smart inverter 122 detects a charging event corresponding to the target vehicle, the smart inverter 122 can obtain a reference charging frequency at which the target vehicle is charged using the battery pack, which can 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 the charging event corresponding to the target vehicle occurs.

[0028] In an alternative embodiment, the smart inverter 122 may obtain a first historical number of times that the target vehicle completed charging within a preset period before the target charging time at which a charging event occurs, and a second historical number of times that the target vehicle completed charging using the battery pack 123 within the preset period before the target charging time. The smart inverter 122 may then determine a reference charging frequency at which the target vehicle was charged using the battery pack 123 based on the first historical number of times that the target vehicle completed charging within the preset period before the target charging time and the second historical number of times that the target vehicle completed charging using the battery pack 123 within the preset period. The preset period may be predefined, preconfigured, or input by an administrator. For example, the preset period may be 10 days or 30 days.

[0029] Preset when the target vehicle is before the target charging time period The first historical charging count for charging completed within a certain period may include the number of times charging of the target vehicle is completed using the battery pack 123, the number of times charging of the target vehicle is completed using the tram control system 11, and the number of times charging of the target vehicle is completed using both the battery pack 123 and the tram control system 11. The process of completing charging of the target vehicle includes, but is not limited to, fully charging the target vehicle.

[0030] Alternatively, the reference charging frequency of charging the target vehicle using the battery pack 123 is a ratio of a first historical charging number of times the target vehicle completed charging within a preset period before the target charging time to a second historical charging number of times the target vehicle completed charging using the battery pack 123 within a preset period. For example, assume that the second historical charging number of times the target vehicle completed charging using the battery pack 123 within a preset period before the target charging time at which a charging event occurs is 5, and the first historical charging number of times the target vehicle completed charging within a preset period before the target charging time is 10. The smart inverter 122 determines the reference charging frequency of charging the target vehicle using the battery pack 123 to be 0.5 based on the first historical charging number of 10 and the second historical charging number of 5.

[0031] Optionally, the smart inverter 122 may obtain a first historical charging count at which the target vehicle has completed charging within a plurality of preset periods before the target charging time, and a second historical charging count at which the target vehicle has completed charging using the battery pack 123 within a plurality of preset periods before the target charging time. Then, the smart inverter 122 may determine an intermediate reference charging frequency at which the target vehicle has been charged using the battery pack 123 based on the first historical charging count and the second historical charging count corresponding to each of the plurality of preset periods, and further performs an average calculation on the intermediate reference charging frequencies corresponding to each of the plurality of preset periods to determine a reference charging frequency at which the target vehicle has been charged using the battery pack 123.

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

[0033] In some possible embodiments, if the smart inverter 122 determines that the reference charging frequency is equal to or less than a first preset frequency, and detects that the charging port connected to the target vehicle is a fast charging port, the smart inverter 122 can use the tram control system to charge the target vehicle in fast charging mode. The first preset frequency is a frequency threshold preset through big data analysis that indicates low user sensitivity to charging costs.

[0034] Note that the value of the first preset frequency is relatively small. If the smart inverter 122 determines that the reference charging frequency is equal to or lower than 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 use the tram control system 11 to charge the target vehicle. Note that when using the tram control system 11 to charge the target vehicle, if the charging port connected to the target vehicle is a fast charging port, the fast charging port can meet the fast charging needs of the target vehicle, and the target vehicle is charged in fast charging mode. If the charging port connected to the target vehicle is a non-fast charging port, the target vehicle is charged in non-fast charging mode. Furthermore, when using the tram control system 11 to charge the target vehicle, the user needs to make the corresponding payment in accordance with the tram billing standards to complete the charging.

[0035] Optionally, if the smart inverter 122 determines that the reference charging frequency is equal to or lower than the first preset frequency, it can send an identity identification message to the charging cable of the target vehicle to identify cable information of the charging cable of the target vehicle. If the charging cable of the target vehicle is a fast charging cable, when the charging cable of the target vehicle receives the identity identification message, it 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 charging cable of the target vehicle, 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 tram control system 11 to charge the target vehicle in fast charging mode.

[0037] S303: When it is detected that the charging port connected to the target vehicle is a non-quick charging port, output a quick charging prompt message through the terminal device to remind the user to use the quick charging port for charging.

[0038] In some possible embodiments, when the smart inverter 122 detects that the charging port connected to the target vehicle is a non-quick charging port, it outputs a quick charging prompt message via the terminal device 13 to remind the user to charge using the quick charging port.

[0039] Optionally, refer to Fig. 4, which is a schematic diagram showing an interface display of a quick charge prompt message according to an embodiment of the present application. As shown in Fig. 4, when the smart inverter 122 detects that the charging port connected to the target vehicle is a non-quick charge port, it can output a quick charge prompt message through the terminal device 13. The quick charge prompt message can be "Please change the charging port to a quick charge port", reminding the user to use the quick charge port for charging.

[0040] S304: When it is detected that the charging port connected to the target vehicle has been updated from a non-rapid charging port to a rapid charging port, the target vehicle is charged in rapid charging mode using the tram control system.

[0041] In some possible embodiments, the smart inverter 122 can again detect whether the charging port connected to the target vehicle is a fast charging port after outputting the fast charging prompt message via the terminal device 13. 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 tram 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-quick charging port, the target vehicle is charged in a non-quick charging mode using the tram control system.

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

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

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

[0046] Furthermore, if the reference charging frequency of the target vehicle 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 tram control system 11. Therefore, after it is determined that the reference charging frequency of the target vehicle 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 can be displayed to the user together, so that the target charging mode intended by the user can be determined.

[0047] Alternatively, the target charging mode may be any one of a first charging mode in which the target vehicle is charged using the battery pack 123, a second charging mode in which the target vehicle is charged using the tram control system 11, and a third charging mode in which the target vehicle is charged using the battery pack 123 and the tram control system 11.

[0048] In an alternative embodiment, when the smart inverter 122 determines that the reference charging frequency of the target vehicle is greater than the first preset frequency and less than or equal to the second preset frequency, the smart inverter 122 can display a plurality of selectable charging modes to the user via the terminal device 13. The plurality of selectable charging modes can 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 tram control system 11, and a third charging mode that charges the target vehicle using the battery pack 123 and the tram control system 11.

[0049] Specifically, referring to Fig. 5, Fig. 5 is a schematic diagram illustrating an interface display of a charging mode according to an embodiment of the present application. As shown in Fig. 5, the terminal device 13 can display the above three selectable charging modes to the user, allowing the user to select the intended target charging mode.

[0050] Optionally, referring to FIG. 6, FIG. 6 is a schematic diagram showing an interface display of another charging mode according to an embodiment of the present application. The smart inverter 122 can obtain a first current remaining energy amount of the target vehicle and a second current remaining energy amount of the battery pack 123, and can determine reference charging periods and reference charging costs corresponding to the first charging mode, the second charging mode, and the third charging mode, respectively, based on the first current remaining energy amount of the target vehicle, the second current remaining energy amount of the battery pack 123, and the city electricity billing standard. As shown in FIG. 6, the terminal device 13 can display three selectable charging modes and reference charging periods and reference charging costs corresponding to each of the three selectable charging modes to the user, allowing the user to select the intended target charging mode.

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

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

[0053] In some possible embodiments, the smart inverter 122 can obtain the user's intended target charging mode via the terminal device 13 and then charge the target vehicle in the target charging mode.

[0054] In an alternative embodiment, when the target charging mode is the third charging mode, the smart inverter 122 may obtain a first current remaining energy amount of the target vehicle at a target charging time when a charging event occurs, a second current remaining energy amount of the battery pack 123 at the target charging time, and multiple historical power supply amounts of the battery pack 123 generated within multiple history periods corresponding to the target charging time, and perform statistical analysis on the multiple historical power supply amounts to predict and obtain a reference power supply amount of the battery pack 123 within a current period in which the target charging time occurs. Next, the smart inverter 122 may determine a target power amount of the target vehicle based on the 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 power amount. When the smart inverter 122 determines that the remaining energy of the target vehicle has reached the target energy, it stops charging the target vehicle using the battery pack 123 and starts charging the target vehicle using the tram control system 11.

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

[0056] The period may be a plurality of predefined and preconfigured time periods, or may be a plurality of time periods obtained by dividing 24 hours of a day according to the actual situation by the administrator. The plurality of history periods corresponding to the target charging time here may be one of the plurality of time periods corresponding to each day before the target charging time. No. 1 The period may be the current period among multiple time periods in which the target charging time at which a charging event occurs is located. For example, 24 hours in a day can be divided into 24 time periods such as 7:00 to 8:00, 8:00 to 9:00, and 9:00 to 10:00. As another example, 24 hours in a day can be divided into 12 time periods such as 7:30 to 9:30, 9:30 to 11:30, and 11:30 to 13:30. After determining the target charging time at which a charging event occurs, multiple history periods corresponding to the target charging time can be determined from the multiple periods based on the target charging time. For example, assuming that the target charging time at which a charging event occurs is 8:30, the history period corresponding to the target charging time 8:30 can be determined to be 8:00 to 9:00.

[0057] Specifically, when the smart inverter 122 detects a charging event corresponding to the target vehicle, it may determine a plurality of history periods corresponding to a target charging time at which the charging event occurs. Next, the smart inverter 122 obtains a plurality of historical power supply amounts of the battery pack 123 generated within a plurality of history periods within a preset number of days before the target charging time, and further performs statistical analysis on the plurality of historical power supply amounts generated within the plurality of history periods within a preset number of days before the target charging time. Then, it may perform an average calculation on one or more historical power supply amounts that are greater than a preset threshold among the plurality of historical power supply amounts to obtain a reference power supply amount of the battery pack 123 within a current period in which the target charging time is located. Note that by determining one or more historical power supply amounts that are greater than a preset threshold among the plurality of historical power supply amounts, low historical power supply amounts due to special circumstances, such as being out, can be excluded from the calculation of the reference power supply amount, thereby avoiding an influence on the calculation of the reference power supply amount.

[0058] For example, before the target charging time 1 of Within 0 days history Assume that the historical power supply amounts of the battery pack 123 corresponding to the periods are 2 kW·h, 1 kW·h, 2 kW·h, 0.5 kW·h, 1 kW·h, 1 kW·h, 2 kW·h, 0.3 kW·h, 1 kW·h, and 2 kW·h, respectively. Assume that the preset threshold is 0.8 kW·h. 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 before the target charging time, and perform statistical analysis on these 10 historical power supply amounts. Then, the smart inverter 122 can compare these 10 historical power supply amounts with the preset threshold and average the historical power supply amounts that are greater than the preset threshold. Specifically, the smart inverter 122 can obtain the historical power supply amounts from the historical power supply amounts. 8 By averaging these values, the reference power supply amount of the battery pack 123 in the current period in which the target charging time is located can be determined to be 1.5 kW·h.

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

[0060] In some possible embodiments, the smart inverter 122 may utilize the battery pack 123 to charge the target vehicle if it determines that the reference charging frequency of the target vehicle is greater than the second preset frequency.

[0061] Note that the reference charging frequency of the target vehicle being greater than the second preset frequency 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 reference charging frequency of the target vehicle is greater than the second preset frequency, the battery pack 123 can be used preferentially to charge the target vehicle.

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

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

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

[0065] The second preset machine learning model may be a convergence machine learning model obtained by performing model training using a large amount of sample data. Each of the plurality of sample data may include the amount of power consumed each time the target vehicle is charged using the battery pack 123 in a plurality of power supply processes for the target vehicle, and the history of the battery pack 123 during a first period in which the target charging times at which each charging event occurs are located. Rekiden The sample data may include the amount of power supply and the amount of remaining power in the battery pack 123 at the target charging time when each charging event occurs. Each of the plurality of sample data may correspond to the maximum amount of power that the battery pack 123 can supply to the target vehicle.

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

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

[0068] For example, assume that the current period is from 5:30 to 6:30. If the smart inverter 122 determines that the reference power supply amount within the current period is greater than the preset power supply amount, it can determine the end time of the current period as 6:30 based on the current period from 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] Optionally, if the smart inverter 122 determines that the reference power supply amount within 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 can 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 in which the target charging time lies. 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 start charging the target vehicle using the battery pack 123.

[0070] In an embodiment of the present application, the smart inverter 122 in the home energy management system 10 can determine the magnitude relationship between the reference charging frequency and the first preset frequency, and the magnitude relationship between the reference charging frequency and the second preset frequency, when the battery pack 123 is used to charge the target vehicle, thereby determining a charging control strategy for charging the target vehicle, and further using the battery pack and / or the tram control system to charge the target vehicle, thereby improving the intelligence and comprehensiveness of the charging control for new energy vehicles by the home energy management system, expanding the boundary of energy management functions, and enabling flexible charging of new energy vehicles.
