With the advent of the intelligent and information age, the demand for electricity has significantly increased. To alleviate pressure from environmental pollution, energy consumption, and other aspects, home energy storage systems are gradually entering thousands of households.
In the related art, in households, electrical energy can be supplied to various home appliances via solar photovoltaic panels, and also electrical energy generated by photovoltaic power can be stored into a battery pack by using energy storage technology, so that electrical energy can be supplied by the battery pack when needed. In practical applications, new energy vehicles may also be connected to the home energy storage system to be charged. However, due to the output power limitations of the home energy storage system, generally, the fast-charging demand of new energy vehicles cannot be met. Therefore, when a new energy vehicle is connected to the home energy storage system to be charged, there may be a mismatch between demand and supply, leading to the possibility of charging failure or low charging efficiency, which affects the normal use of the new energy vehicle. Therefore, how to flexibly use the home energy storage system to charge new energy vehicles has become one of the technical problems that need to be solved urgently.

A fast-charging prompt message is outputted via the terminal device to prompt a user to use the fast-charging port for charging in the case where the charging port accessed by the target vehicle is detected to be a non-fast-charging port. The target vehicle is charged in the fast-charging mode through the mains-borne control system in the case where it is detected that the charging port accessed by the target vehicle has been updated from the non-fast-charging port to the fast-charging port. The target vehicle is charged in a non-fast-charging mode through the mains-borne control system in the case where the charging port accessed by the target vehicle is detected to remain the non-fast-charging port. A target charging mode preferred by the user is acquired via the terminal device in the case where the reference charging frequency of the target vehicle is determined to be greater than the first preset frequency and less than or equal to a second preset frequency, where the second preset frequency is a frequency threshold for users with high sensitivity to charging costs, preset through big data analysis. The target vehicle is charged in the target charging mode.

At S301, a reference charging frequency at which a target vehicle has been charged through the battery pack is acquired in the case where a charging event corresponding to the target vehicle is detected.
In some possible embodiments, the reference charging frequency at which the target vehicle has been charged through the battery pack is acquired in the case where the smart inverter 122 detects the charging event corresponding to the target vehicle. The reference charging frequency indicates a frequency at which the smart inverter 122 has charged the target vehicle using only the battery pack 123 prior to the charging event corresponding to the target vehicle.
In an optional embodiment, the smart inverter 122 may acquire the number of first historical charging times that the target vehicle has been charged within a preset period prior to target charging time at which the charging event occurs, and the number of second historical charging times that the target vehicle has been charged through the battery pack 123 within the preset period prior to the target charging time. Further, the smart inverter 122 may determine the reference charging frequency at which the target vehicle has been charged through the battery pack 123 according to the number of first historical charging times that the target vehicle has been charged within the preset period prior to the target charging time and the number of second historical charging times that the target vehicle has been charged through the battery pack 123 within the preset period prior to the target charging time. Here, the preset period may be predefined, pre-configured, or input by an administrator. For example, the preset period may be 10 days, 30 days, etc.
The number of first historical charging times that the target vehicle has been charged within the preset period prior to the target charging time may include, but is not limited to, the number of times that a process of charging the target vehicle through the battery pack 123 has been completed, the number of times that a process of charging the target vehicle through the mains-borne control system 11 has been completed, and the number of times that a process of charging the target vehicle through both the battery pack 123 and the mains-borne control system 11 has been completed. It may be noted that a process through which charging the target vehicle has been completed may include, but is not limited to, a process through which the target vehicle is fully charged.
Optionally, the reference charging frequency at which the target vehicle has been charged through the battery pack 123 is a ratio of the number of second historical charging times, within the preset period, that charging the target vehicle through the battery pack 123 has been completed to the number of first historical charging times, within the preset period prior to the target charging time, that charging the target vehicle has been completed. For example, assuming that the number of second historical charging times, within the preset period prior to the target charging time at which the charging event occurs, that charging the target vehicle through the battery pack 123 has been completed is 5, and the number of first historical charging times, within the preset period prior to the target charging time, that charging the target vehicle has been completed is 10. The smart inverter 122 may determine that the reference charging frequency at which the target vehicle has been charged through the battery pack 123 is 0.5 according to the number of first historical charging times, 10, and the number of second historical charging times, 5.
Optionally, the smart inverter 122 may obtain the number of first historical charging times, within multiple preset periods prior to the target charging time, that charging the target vehicle has been completed, and the number of second historical charging times, within the multiple preset periods prior to the target charging time, that charging the target vehicle through the battery pack 123 has been completed. Further, for each of the multiple preset periods, the smart inverter 122 may determine an intermediate reference charging frequency at which the target vehicle has been charged through the battery pack 123 according to the number of first historical charging times corresponding to the preset period and the number of second historical charging times corresponding to the preset period. Further, the smart inverter 122 may determine the reference charging frequency at which the target vehicle has been charged through the battery pack 123 by calculating an average of multiple intermediate reference charging frequencies each corresponding to an individual one of the multiple preset periods.
At S302, the target vehicle is charged in a fast-charging mode through the mains-borne control system in the case where the reference charging frequency is determined to be less than or equal to a first preset frequency and a charging port accessed by the target vehicle is detected to be a fast-charging port.
In some possible embodiments, the target vehicle is charged in the fast-charging mode through the mains-borne control system in the case where the smart inverter 122 determines that the reference charging frequency is less than or equal to the first preset frequency and the charging port accessed by the target vehicle is detected to be a fast-charging port. Here, the first preset frequency is a frequency threshold preset for users with low sensitivity to charging costs, preset through big data analysis.
It may be noted that the first preset frequency is relatively low. In the case where the smart inverter 122 determines that the reference charging frequency is less than or equal to the first preset frequency, it indicates that the user rarely or occasionally uses the battery pack 123 in the home energy storage system 12 to charge the target vehicle, and then the smart inverter 122 may directly use the mains-borne control system 11 to charge the target vehicle. It may be understood that in the case where the target vehicle is charged through the mains-borne control system 11 and the charging port accessed by the target vehicle is a fast-charging port, it indicates that the fast-charging requirements of the target vehicle can be satisfied, and the target vehicle can be charged in the fast-charging mode. In the case where the charging port accessed by the target vehicle is a non-fast-charging port, the vehicle can be charged in the non-fast-charging mode. Meanwhile, in the case where the target vehicle is charged through the mains-borne control system 11, the user needs to pay corresponding fee according to the city electricity charging standard to complete charging.
Optionally, in the case where the smart inverter 122 determines that the reference charging frequency is less than or equal to the first preset frequency, the smart inverter 122 may send an identity discovery message to a charging cable of the target vehicle to identify cable information of the charging cable of the target vehicle. In the case where the charging cable of the target vehicle is a fast-charging cable and the charging cable of the target vehicle receives the identity discovery message, a response message may be generated and sent to the smart inverter 122. Further, in the case where the response message sent by the charging cable of the target vehicle is received by the smart inverter 122, the smart inverter 122 may determine that the charging cable is a fast-charging cable, i.e., determine that the charging port accessed by the target vehicle is a fast-charging port.
Further, the smart inverter 122 may use the mains-borne control system 11 to charge the target vehicle in the fast-charging mode in the case where the smart inverter 122 determines that the charging port accessed by the target vehicle is a fast-charging port.
At S303, a fast-charging prompt message is output via the terminal device to prompt the user to use a fast-charging port for charging in the case where it is detected that the charging port accessed by the target vehicle is a non-fast-charging port.
In some possible embodiments, the fast-charging prompt message is outputted via the terminal device 13 to prompt the user to use the fast-charging port for charging in the case where the smart inverter 122 detects that the charging port accessed by the target vehicle is a non-fast-charging port.
Optionally, referring to
At S304, the target vehicle is charged in the fast-charging mode through the mains-borne control system in the case where it is detected that the charging port accessed by the target vehicle has been updated from the non-fast-charging port to the fast-charging port.
In some possible embodiments, after the smart inverter 122 outputs the fast-charging prompt message via the terminal device 13, the smart inverter 122 may re-detect whether the charging port accessed by the target vehicle is a fast-charging port. The smart inverter 122 can charge target vehicle in the fast-charging mode through the mains-borne control system 11 in the case where the smart inverter 122 detects that the charging port accessed by the target vehicle has been updated from the non-fast-charging port to the fast-charging port.
At S305, the target vehicle is charged in a non-fast-charging mode through the mains-borne control system in the case where the charging port accessed by the target vehicle is detected to remain the non-fast-charging port.
In some possible embodiments, after the smart inverter 122 outputs the fast-charging prompt message via the terminal device 13, the smart inverter 122 may re-detect whether the charging port accessed by the target vehicle is a fast-charging port. The smart inverter 122 can charge the target vehicle in the non-fast-charging mode through the mains-borne control system 11 in the case where the smart inverter 122 detects that the charging port accessed by the target vehicle remains the non-fast-charging port.
At S306, a target charging mode preferred by the user is acquired via the terminal device in the case where the reference charging frequency of the target vehicle is determined to be greater than the first preset frequency and less than or equal to a second preset frequency. In some possible embodiments, the smart inverter 122 can acquire the target charging mode preferred by the user via the terminal device in the case where 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 a second preset frequency, where the second preset frequency is the frequency threshold for users with high sensitivity to charging costs, preset through big data analysis. The target charging mode is a charging control mode in which the smart inverter 122 is to charge the target vehicle.
It is noted that in the case where 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 indicates that the user frequently uses the battery pack 123 of the home energy storage system 12 to charge the target vehicle, and also frequently uses the mains-borne control system 11 to charge the target vehicle. 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, charging cost and charging duration of charging modes may be displayed to the user, to determine the target charging mode preferred by the user.
Optionally, the target charging mode may be any one of the following charging modes: a first charging mode in which the target vehicle is charged through the battery pack 123, a second charging mode in which the target vehicle is charged through the mains-borne control system 11, and a third charging mode in which the target vehicle is charged though both the battery pack 123 and the mains-borne control system 11.
In an optional embodiment, in the case where 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 multiple selectable charging modes to the user via the terminal device 13. The multiple selectable charging modes include at least the first charging mode in which the target vehicle is charged through the battery pack 123, the second charging mode in which the target vehicle is charged through the mains-borne control system 11, and the third charging mode in which the target vehicle is charged though both the battery pack 123 and the mains-borne control system 11.
Specifically, referring to
Optionally, referring to
Furthermore, in the case where the smart inverter 122 detects a charging mode selection instruction input by the user for the multiple selectable charging modes, the smart inerter 122 can determine the target charging mode preferred by the user from the multiple selectable charging modes according to the charging mode selection instruction.
At S307, the target vehicle is charged in the target charging mode.
In some possible embodiments, after obtaining the target charging mode preferred by the user through the terminal device 13, the smart inverter 122 may charge the target vehicle in the target charging mode.
In an optional embodiment, in the case where the target charging mode is the third charging mode, the smart inverter 122 may acquire the first current remaining power of the target vehicle at the target charging time at which the charging event occurs, the second current remaining power of the battery pack at the target charging time, and multiple historical power supply amounts of the battery pack 123 within multiple historical periods corresponding to the target charging time; and predict and obtain a reference power supply amount of the battery pack within a current period in which the target charging time is located by performing statistical analysis on the multiple historical power supply amounts. Further, the smart inverter 122 may determine a target power amount of the target vehicle according to a first preset machine learning model, the first current remaining power, the second current remaining power, and the reference power supply amount. Furthermore, the smart inverter 122 may charge the target vehicle through the battery pack 123 while simultaneously monitoring whether a remaining power of the target vehicle is equal to the target power amount. In the case where the smart inverter 122 determines that the remaining power of the target vehicle reaches the target power amount, the smart inverter 122 may stop charging the target vehicle through the battery pack 123 and switch to charge the target vehicle through the mains-borne control system 11.
The first preset machine learning model may be a converged machine learning model obtained through model training using a large amount of sample data. Each of these multiple sample data may include the remaining power of the target vehicle when each charging event occurs, a remaining power of the battery pack 123 at the target charging time at which each charging event occurs, and the historical power supply amount of the battery pack 123 within a first period in which the target charging time, at which each charging event occurs, is located. Each sample data among the above multiple sample data may correspond to a target power amount of the target vehicle.
The periods may be pre-defined, pre-configured multiple periods, or multiple periods obtained by dividing, by the administrator, the 24 hours of a day according to actual conditions. The multiple historical periods corresponding to the target charging time here may include one period among the aforementioned multiple periods of each day prior to the target charging time. The first period in which the target charging time is located may be the current period, in which the charging event occurs, among the aforementioned multiple periods. For example, the 24 hours of a day may be divided into 24 periods, such as 7:00-8:00, 8:00-9:00, 9:00-10:00, etc. Alternatively, the 24 hours of a day may be divided into 12 periods, 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, the multiple historical periods corresponding to the target charging time may be determined from the aforementioned multiple periods according to the target charging time. For example, if the target charging time at which the charging event occurs is 8:30, the historical period corresponding to the target charging time of 8:30 may be determined as 8:00-9:00.
Specifically, in the case where the smart inverter 122 detects the charging event corresponding to the target vehicle, the smart inverter 122 may determine the multiple historical periods corresponding to the target charging time at which the charging event occurs. Further, the smart inverter 122 may obtain multiple historical power supply amounts of the battery pack 123 within multiple historical periods within a preset number of days prior to the target charging time, and further perform statistical analysis based on the multiple historical power supply amounts generated within multiple historical periods within the preset number of days prior to the target charging time. By averaging one or more historical power supply amounts, that are greater than a preset threshold, among the aforementioned multiple historical power supply amounts, the smart inverter 122 may determine the reference power supply amount of the battery pack 123 within the current period in which the target charging time is located. It may be understood that by determining one or more historical power supply amounts, that are greater than the preset threshold, among the above multiple historical power supply amounts, the low values of the historical power supply amounts caused by special circumstances, such as being away from home, are excluded from being used as a basis for calculating the reference power supply amount, thereby preventing any adverse impact on the calculation of the reference power supply amount.
For example, the historical power supply amounts, corresponding to historical periods, within the preset 10 days prior to the target charging time are supposed to be 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, 2 kW·h. The preset threshold is supposed to be 0.8 kW·h. The smart inverter 122 may obtain 10 historical power supply amounts, corresponding to 10 historical periods that correspond to the target charging time, within the preset number of days prior to the target charging time, and perform statistical analysis on these 10 historical power supply amounts. Further, the smart inverter 122 may compare these 8 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 may average the 10 historical power supply amounts, 2 kW·h, 1 kW·h, 2 kW·h, 1kW·h, 1kW·h, 2kW·h, 1 kW·h, and 2 kW·h, and determine that the reference power supply amount of the battery pack 123 within the current period corresponding to the target charging time is 1.5 kW·h.
At S308, the target vehicle is charged through the battery pack in the case where the reference charging frequency of the target vehicle is determined to be greater than the second preset frequency.
In some possible embodiments, the smart inverter 122 may charge the target vehicle through the battery pack 123 in the case where the smart inverter 122 determines that the reference charging frequency of the target vehicle is greater than the second preset frequency.
It may be noted that in the case where the reference charging frequency of the target vehicle is greater than the second preset frequency, it may indicate that the user frequently uses the battery pack 123 of the home energy storage system 12 to charge the target vehicle. Therefore, after determining that the reference charging frequency of the target vehicle is greater than the second preset frequency, the battery pack 123 can be given priority to charge the target vehicle.
In an optional embodiment, the smart inverter 122 may acquire multiple historical power supply amounts of the battery pack 123 within multiple historical periods corresponding to the target charging time at which the charging event occurs and further determine the reference power supply amount of the battery pack within the current period in which the target charging time is located by performing statistical analysis on the multiple historical power supply amounts. Furthermore, the target vehicle may be charged through the battery pack 123 in the case where the smart inverter 122 determines that the reference power supply amount within the current period is less than or equal to the preset power supply amount.
The preset power supply amount may be an empirical value. The preset power supply amount may be pre-configured or input by an administrator. The preset power supply amount is compared with the reference power supply amount within the current period, to determine whether the battery pack 123 is at a power supply peak within the current period, so that whether to charge the target vehicle through the battery pack 123 within the current period can be determined. For example, in the case where the reference power supply amount within the current period is less than or equal to the preset power supply amount, it may be determined that the battery pack 123 is not at a power supply peak within the current period, and thus the battery pack 123 may be used to charge the target vehicle within the current period. In the case where the reference power supply amount of the current period is greater than the preset power supply amount, it may be determined that the battery pack 123 is at a power supply peak within the current period, and the battery pack 123 may be used to charge the target vehicle after the current period elapses, or the battery pack 123 may be used to charge the target vehicle at a limited power within the current period.
In an optional embodiment, in the case where 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 can obtain multiple historical power consumption amounts of the battery pack corresponding to multiple charging processes of the target vehicle that have been performed through the battery pack 123 prior to the target charging time,, and further can determine a reference power consumption amount for each charging process of the target vehicle that has been performed through the battery pack 123 according to the multiple historical power consumption amounts. The smart inverter 122 may obtain the second current remaining power of the battery pack 123 at the target charging time. Further, the smart inverter 122 may determine a maximum power supply amount that the battery pack 123 is capable of providing to the target vehicle within the current period, according to a second preset machine learning model, the reference power consumption amount, the reference power supply amount, and the second current remaining power. The maximum power supply amount may be the maximum amount of power that the battery pack 123 is capable of providing to the target vehicle within the current period. Further, the smart inverter 122 may determine the target power that the battery pack is capable of charging the target vehicle within the current period according to the reference power supply amount and the maximum charging duration, and use the battery pack 123 to charge the target vehicle at the target power.
The second preset machine learning model may be a converged machine learning model obtained through model training with a large number of sample data. Each of these multiple sample data may include the power consumption amount of the battery pack 123 for charging the target vehicle during each of multiple power supply processes for the target vehicle, a historical power supply amount of the battery pack 123 within the first period in which the target charging time, at which each charging event occurs, is located, and the remaining power of the battery pack 123 at the target charging time at which each charging event occurs. Each of these multiple sample data may correspond to the maximum amount of power that the battery pack 123 can provide to the target vehicle.
For example, taking a target vehicle with a battery capacity of 30 kW·h as an example, the historical power consumption amounts of the battery pack 123 for charging the target vehicle during 10 charging processes prior to the target charging time are supposed to be 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, 22 kW·h. The reference power supply amount within the current period is supposed to be 2 kW·h. The second current remaining power of the battery pack 123 is supposed to be 20 kW·h. The target charging time is 5:30, and the current period corresponding to the target charging time is supposed to be 5:00-6:00. The smart inverter 122 may average the historical power consumption amounts for charging the target vehicle during 10 charging processes prior to the target charging time, to determine that the reference power consumption amount for each charging process in which the target vehicle has been charged through the battery pack 123 is 21.1 kW·h. Further, the smart inverter 122 may determine the maximum power supply amount that the battery pack 123 is capable of providing to the target vehicle within the current period is 10 kW·h, according to the second preset machine learning model, the reference power consumption amount of 21.1 kW·h, the reference power supply amount of 2 kW·h, and the second current remaining power of 20 kW·h. Further, the smart inverter 122 may determine that the maximum charging duration of the target vehicle within the target period is 0.5 hours according to the target charging time of 5:30 and the current period of 5:00-6:00. The smart inverter 122 may determine that the reference power supply amount that the battery pack 123 is capable of providing to the target vehicle within the maximum charging duration is 5 kW·h according to the maximum power supply amount of 10 kW·h and the maximum charging duration of 0.5 hours.
