It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The power supply control method of the charging station provided by the present application can be applied to the power supply system of the charging station as shown in FIG. 1 . As shown in Figure 1, the power supply system of the charging station includes a charging management controller, photovoltaic cells, storage batteries, a mains interface, a power supply switch, a power bus, a charging interface and a charging control switch. Wherein, the charging interface is connected with the power bus, and the power supply switch is connected with the power bus. The power supply switch is connected with the photovoltaic cell, the storage battery and the mains interface respectively, and is used for switching the three power supplies of the photovoltaic cell, the storage battery and the mains interface. The charging control switch is connected with the charging interface for controlling the power supply speed. The charging management controller is connected with the charging interface and the power supply switch, and is used for controlling the power supply switch and the charging control switch, so as to realize the power supply control method of the charging station.

Among them, the charging management controller can be implemented by a server, and can also be applied to a system including a terminal and a server, and implemented by interaction between the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server can be implemented as an independent server or a server cluster composed of multiple servers.

Specifically, when it is detected that the current vehicle is connected to the charging station, the charging management controller obtains the remaining power of the current vehicle and the remaining power of other vehicles in the charging station through the charging control switch. The charging management controller determines the charging state of the current vehicle according to the remaining power of the current vehicle and the remaining power of other vehicles. According to the remaining power of other vehicles, the target charging power of other vehicles is calculated. The charge management controller obtains the power of different types of power supply batteries in the charging station through the power supply switch.

Further, the charge management controller determines the target power supply mode of the current vehicle according to the current state of charge of the vehicle, the target charge power of other vehicles, the power levels of different types of power supply batteries, and the priorities of different types of power supply batteries. The charging management controller controls the charging station to supply power to the current vehicle through the target power supply mode by controlling the power supply switch and the charging control switch.

In one embodiment, as shown in FIG. 2 , a method for controlling power supply of a charging station is provided, and the method is applied to the charging management controller in FIG. 1 as an example for description, including the following steps:

Step 202, when it is detected that the current vehicle is connected to the charging station, obtain the remaining power of the current vehicle.

Among them, similar to gas stations, charging stations are public places for charging electric vehicles. The electric vehicle may be an electric bicycle, an electric car, or the like. The current vehicle is the vehicle currently connected to the charging station and waiting to be charged. The remaining charge of the current vehicle is the charge value of the current vehicle.

Specifically, the charge management controller is connected to the charge interface through a charge control switch. When the charging interface detects that a vehicle is connected, the charging control switch is turned on, and the charging management controller can obtain the remaining power of the currently connected vehicle through the charging interface.

Step 204: Obtain the remaining power of other vehicles in the charging station, and determine the charging state of the current vehicle according to the remaining power of the current vehicle and the remaining power of other vehicles.

The other vehicles in the charging station are vehicles that are connected before the current vehicle is connected to the charging station, and may be vehicles that have completed charging, vehicles that are being charged, or vehicles that are waiting to be charged. The remaining charge of other vehicles is the charge value of other vehicles. Specifically, it may refer to the remaining power corresponding to other vehicles when the current vehicle is connected to the charging station.

Specifically, in the same way as the method for obtaining the remaining power of the current vehicle, the charging management controller can obtain the remaining power of other vehicles in the charging station through the charging interface. After obtaining the remaining power of the current vehicle and the remaining power of other vehicles in the charging station, the charging management controller can determine the charging state of the current vehicle according to the remaining power of the current vehicle and the remaining power of other vehicles.

For example, the remaining power of the current vehicle and the remaining power of other vehicles are both less than or equal to the preset vehicle power threshold, the remaining power of the current vehicle and the remaining power of other vehicles are both greater than the preset vehicle power threshold, etc.

Step 206: Calculate and obtain the target charging power of other vehicles according to the remaining power of other vehicles.

The target charging power refers to the charging power required by the vehicle.

Specifically, when acquiring the remaining power of other vehicles, the charging management controller may also acquire battery models of other vehicles, and determine the stored power of other vehicles according to the battery models of other vehicles. The charge management controller subtracts the remaining power of other vehicles from the stored power of other vehicles to obtain the target charging power of other vehicles.

In one embodiment, the charge management controller may also multiply the stored power of the other vehicle by a proportional coefficient and then subtract the remaining power of the other vehicle to obtain the target charging power of the other vehicle. For example, set the scale factor to 90%.

Step 208: Obtain the power of different types of power supply batteries in the charging station and the priorities of different types of power supply batteries.

Among them, different types of power supply batteries include photovoltaic cells and storage batteries. The priority of different types of power supply batteries is determined by the nature of the power supply batteries. Compared with batteries, photovoltaic cells, as a new energy source, can convert light energy into electrical energy, save fuel energy and effectively protect the environment. Therefore, when selecting the target power supply source, photovoltaic cells take precedence over batteries.

Specifically, the charge management controller is connected to different types of power supply batteries through a plurality of power supply switches, and the charge management controller can obtain the power of different types of power supply batteries, that is, the power of photovoltaic cells and the power of batteries. When the current vehicle is connected, the power corresponding to the photovoltaic battery and the power corresponding to the battery. In addition, the charge management controller also stores the priorities of different types of power supply batteries, which can be directly obtained by the charge management controller.

Step 210: Determine the target power supply mode of the current vehicle according to the current charging state of the vehicle, the target charging power of other vehicles, the power of different types of power supply batteries, and the priorities of different types of power supply batteries.

The target power supply mode includes a target power supply speed and a target power supply. The target power supply speed includes a first power supply speed, a second power supply speed, and a power supply pause, and the first power supply speed is greater than the second power supply speed. The target power supply includes photovoltaic cells, storage batteries and utility power. When selecting a target power supply, photovoltaic cells take precedence over batteries. The use of mains power will increase the load of the mains grid, so the battery has priority over the mains.

Specifically, the charge management controller adds the power of different types of power supply batteries, that is, the power of the photovoltaic cell and the power of the storage battery, to obtain the total power of the battery of the charging station. The charge management controller compares the target charge level of other vehicles with the total battery level of the charging station, and obtains the comparison result. According to the current charging state of the vehicle and the above comparison result, the charging management controller may determine the target power supply speed corresponding to the current vehicle.

Combined with the current state of charge of the vehicle and the above comparison results, the charge management controller determines the target power supply for the current vehicle according to the power levels of different types of power supply batteries and the priorities of different types of power supply batteries. For example, when the power of the photovoltaic battery is greater than or equal to the preset battery power threshold, the photovoltaic battery is used as the target power supply for the current vehicle, and the photovoltaic battery is given priority to supply power to the current vehicle.

Step 212, controlling the charging station to supply power to the current vehicle through the target power supply mode.

Specifically, after determining the target power supply speed and target power supply of the current vehicle, the charging management controller controls the output power of the charging interface through the charging control switch, and switches to the interface of the corresponding target power supply through the power supply switching switch, thereby controlling the charging station The current vehicle is powered by the target power supply speed and the target power supply source.

In one embodiment, the charging management controller calculates and obtains the target charging power of the current vehicle according to the remaining power of the current vehicle. When the charging station is controlled to supply power to the current vehicle through the target power supply mode, the real-time power of the current vehicle is obtained at regular intervals. When the real-time power of the current vehicle is greater than or equal to the target charging power of the current vehicle, the charging management controller Control the switch to control the charging station to stop supplying power to the current vehicle.

In the above-mentioned power supply control method of the charging station, when it is detected that the current vehicle is connected to the charging station, the remaining power of the current vehicle, the remaining power of other vehicles in the charging station, the power of different types of power supply batteries, and the power of different types of power supply batteries are obtained. According to the remaining power of the current vehicle and the remaining power of other vehicles, the charging state of the current vehicle is determined, and the target charging power of other vehicles is calculated according to the remaining power of other vehicles. The charging power, the power of different types of power supply batteries and the priorities of different types of power supply batteries determine the target power supply mode of the current vehicle, and can determine the target power supply mode of the current vehicle in different charging states, so as to control the charging station to supply power through the target The mode supplies power to the current vehicle, effectively reducing the load of the mains grid.

In one embodiment, as shown in FIG. 3, step 210 includes:

Step 302, when the remaining power of the current vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is less than or equal to the preset vehicle power threshold, calculate the total battery power of the charging station according to the power of different types of power supply batteries;

Step 304, when the total battery power is greater than the target charging power of other vehicles, obtain a first power supply speed;

Step 306: Determine the target power supply source of the current vehicle according to the power of different types of power supply batteries and the priorities of different types of power supply batteries;

Step 308, the target power supply mode of the current vehicle is obtained from the combination of the first power supply speed and the target power supply source.

Wherein, the preset vehicle battery power threshold refers to a low battery threshold value of the vehicle. When the remaining power of the vehicle is less than or equal to the preset vehicle power threshold, it means that the power of the vehicle is too low and needs to be charged urgently.

In one embodiment, the preset vehicle power threshold may be a fixed power value, such as 100Wh (watt-hour). In other embodiments, the preset vehicle power threshold may also be a proportional value, such as 20% of the vehicle's power storage.

Specifically, the charge management controller compares the current remaining power of the vehicle with a preset vehicle power threshold. When the remaining power of the current vehicle is greater than the preset vehicle power threshold, the charge management controller compares the remaining power of other vehicles with the preset vehicle power threshold, so as to determine the charging state of the current vehicle. When the current charging state of the vehicle is that the remaining power of the current vehicle is greater than the preset vehicle power threshold, and the remaining power of other vehicles is less than or equal to the preset vehicle power threshold, the charge management controller calculates and obtains the power according to the power of different types of power supply batteries. The total battery capacity of the charging station. The charging management controller compares the total battery power with the target charging power of other vehicles, and judges whether the battery of the charging station has enough power to supply power to the current vehicle.

In one embodiment, when the total battery power is less than or equal to the target charging power of other vehicles, it is determined that the current target power supply mode of the vehicle is no power supply.

Specifically, since the remaining power of other vehicles is less than or equal to the preset vehicle power threshold, the charge management controller should give priority to supplying power to other vehicles. However, the total battery power in the charging station is less than or equal to the target charging power of other vehicles, indicating that the power supply battery of the charging station does not have enough power to supply power to the current vehicle. In addition, the remaining power of the current vehicle is greater than the preset vehicle power threshold, indicating that the current vehicle is not in a hurry to charge. At this time, the charging management controller can determine that the target power supply mode of the current vehicle is no power supply, saving energy and reducing the power grid. load.

In one embodiment, after determining that the target power supply mode of the current vehicle is no power supply, the charge management controller may estimate the remaining mileage of the current vehicle according to the remaining power of the current vehicle. The charging management controller searches for the current vehicle through the remaining mileage of the current vehicle to find other charging stations that the current vehicle can reach and that have batteries to supply power to the current vehicle. Further, the charging management controller obtains the digital map, formulates a driving route for the current vehicle according to the location information of the current charging station and the location information of other charging stations, and sends the driving route and the location information of other charging stations to the current vehicle, so that The user of the current vehicle chooses whether to travel to another charging station for charging.

In one embodiment, when the total power of the battery is greater than the target charging power of other vehicles, the first power supply speed is obtained, and the first power supply speed is used as the target power supply speed of the current vehicle.

The charging management controller can control the charging interface to output different powers through the charging control switch, and different output powers correspond to different power supply speeds. The first power supply speed is a relatively slow charging speed, corresponding to a small output power.

Specifically, since the remaining power of other vehicles is less than or equal to the preset vehicle power threshold, the charge management controller should give priority to supplying power to other vehicles. Moreover, the total battery power in the charging station is greater than the target charging power of other vehicles, indicating that the battery of the charging station has enough power to supply power to the current vehicle. If the remaining power of the current vehicle is greater than the preset vehicle power threshold, the charge management controller can use the battery in the charging station to supply power to the current vehicle at a slow speed with a small output power.

Further, after taking the first power supply speed as the current target power supply speed of the vehicle, step 306 is entered. Among them, different types of power supply batteries include photovoltaic cells and storage batteries. Step 306 includes: when the power of the photovoltaic battery is greater than or equal to the preset battery power threshold, using the photovoltaic battery as the target power supply of the current vehicle; when the power of the photovoltaic battery is less than the preset battery power threshold, using the battery as the current vehicle target power supply.

The preset battery power threshold refers to the low power threshold of the power supply battery, which is the same as the preset vehicle power threshold. The preset battery power threshold may be a fixed power value or a proportional value.

Specifically, when the power of the photovoltaic cell is greater than or equal to the preset battery power threshold, it means that the photovoltaic cell has enough power to supply power, and at this time, the photovoltaic cell is used as the target power supply for the current vehicle. Since the total battery power of the charging station is greater than the target charging power of other vehicles, when the power of the photovoltaic battery is less than the preset battery power threshold, the charge management controller can use the battery as the target power supply for the current vehicle.

In this embodiment, in a state where the current remaining power of the vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is less than or equal to the preset vehicle power threshold, the total battery power of the charging station is charged with the target of other vehicles. power for comparison. When the total battery power is less than or equal to the target charging power of other vehicles, no power is supplied to the current vehicle, which can effectively reduce the load on the mains grid. When the total battery power is greater than the target charging power of other vehicles, the current vehicle is slowly powered by the power supply batteries in the charging station, and the power of different types of power supply batteries in the charging station and the priorities of different types of power supply batteries are determined. The current target power supply for vehicles can effectively reduce the load on the mains grid and save energy.

In one embodiment, as shown in Figure 4, step 210 includes:

Step 402, when the remaining power of the current vehicle is less than or equal to a preset vehicle power threshold, obtain a second power supply speed;

Step 404: Calculate the total battery power of the charging station according to the power of different types of power supply batteries;

Step 406 , when the total battery power is less than or equal to the target charging power of other vehicles, the target power supply mode of the current vehicle is obtained from the combination of the second power supply speed and the mains interface.

The charging management controller can control the charging interface to output different powers through the charging control switch, and different output powers correspond to different power supply speeds. Compared to the first power supply speed, the second power supply speed is a relatively faster charging speed, corresponding to a larger output power.

Specifically, the charge management controller compares the remaining power of the current vehicle with a preset vehicle power threshold, and when the current vehicle's remaining power is less than or equal to the preset vehicle power threshold, it indicates that the current vehicle is eager to charge. At this time, the charge management controller obtains the second power supply speed, and uses the second power supply speed as the target power supply speed of the current vehicle, so as to realize the fast charging of the current vehicle.

Further, the charge management controller adds the power of different types of power supply batteries to obtain the total power of the batteries of the charging station. The charging management controller compares the total battery power with the target charging power of other vehicles, and judges whether the battery of the charging station has enough power to supply power to the current vehicle.

In one embodiment, when the total battery power is less than or equal to the target charging power of other vehicles, it means that the power supply battery of the charging station does not have enough power to supply power for the current vehicle. The charging management controller connects the mains interface with the charging interface corresponding to the current vehicle by controlling the power supply switch, and can control the charging interface corresponding to the current vehicle to output the power corresponding to the second power supply speed through the charging control switch. Thus, the charging station is controlled to supply power to the current vehicle through the second power supply speed and the mains interface.

In one embodiment, when the total battery power is greater than the target charging power of other vehicles, it means that the power supply battery of the charging station has enough power to supply power to the current vehicle. The charge management controller determines the target power supply source of the current vehicle according to the power of different types of power supply batteries and the priorities of different types of power supply batteries. Specifically, when the power of the photovoltaic battery is greater than or equal to the preset battery power threshold, the photovoltaic battery is used as the target power supply of the current vehicle; when the power of the photovoltaic battery is less than the preset battery power threshold, the battery is used as the current vehicle. Target power supply.

In this embodiment, when the remaining power of the current vehicle is less than or equal to the preset vehicle power threshold, the second power supply speed is obtained, and the current vehicle is quickly powered by the second power supply speed to improve the charging efficiency. And compare the total battery capacity of the charging station to the target charging capacity of other vehicles. When the total battery power is less than or equal to the target charging power of other vehicles, supplying power to the current vehicle through the mains interface can ensure the effective charging of the current vehicle. When the total battery power is greater than the target charging power of other vehicles, the target power supply of the current vehicle is determined by the power of different types of power supply batteries in the charging station and the priorities of different types of power supply batteries, which can effectively reduce the load on the mains grid ,Energy saving.

In one embodiment, as shown in Figure 5, step 210 includes:

Step 502, when the remaining power of the current vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is greater than the preset vehicle power threshold, calculate the total battery power of the charging station according to the power of different types of power supply batteries;

Step 504, when the total battery power of the charging station is less than or equal to the target charging power of other vehicles, determine that the target power supply mode of the current vehicle is no power supply.

Specifically, the charge management controller compares the current remaining power of the vehicle with a preset vehicle power threshold. When the remaining power of the current vehicle is greater than the preset vehicle power threshold, the charge management controller compares the remaining power of other vehicles with the preset vehicle power threshold, so as to determine the charging state of the current vehicle. When the charging state of the current vehicle is that the remaining power of the current vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is greater than the preset vehicle power threshold, it means that the current vehicle and other vehicles are not in a hurry to charge. At this time, the charging management controller compares the total battery power with the target charging power of other vehicles, and determines whether the battery of the charging station has enough power to supply power to the current vehicle.

In one embodiment, when the total battery power is less than or equal to the target charging power of other vehicles, it is determined that the current target power supply mode of the vehicle is no power supply.

Specifically, since the remaining power of the current vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is greater than the preset vehicle power threshold, it means that the power supply battery of the charging station does not have enough power to supply power to the current vehicle. In addition, the remaining power of the current vehicle is greater than the preset vehicle power threshold, indicating that the current vehicle is not in a hurry to charge. At this time, the charging management controller can determine that the target power supply mode of the current vehicle is no power supply, saving energy and reducing the power grid. load.

In one embodiment, when the total battery power is greater than the target charging power of other vehicles, the target power supply of the current vehicle is determined according to the power of different types of power supply batteries and the priorities of different types of power supply batteries. Specifically, when the power of the photovoltaic battery is greater than or equal to the preset battery power threshold, the photovoltaic battery is used as the target power supply of the current vehicle; when the power of the photovoltaic battery is less than the preset battery power threshold, the battery is used as the current vehicle. Target power supply.

Further, since the remaining power of the current vehicle and the remaining power of other vehicles are both greater than the preset vehicle power threshold, the charging station can supply power to the current vehicle through the first power supply speed, the second power supply speed, or other conventional power supply speeds. .

In this embodiment, when the remaining power of the current vehicle is greater than the preset vehicle power threshold and the remaining power of other vehicles is greater than the preset vehicle power threshold, the total battery power of the charging station is compared with the target charging power of other vehicles .
