It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The power supply control method for the charging station provided by the application can be applied to a charging station power supply system shown in fig. 1. As shown in fig. 1, the charging station power supply system includes a charging management controller, a photovoltaic cell, a storage battery, a utility power interface, a power supply switch, a power bus, a charging interface, and a charging control switch. The charging interface is connected with a power bus, and the power supply changeover switch is connected with the power bus. The power supply changeover switch is respectively connected with the photovoltaic cell, the storage battery and the commercial power interface and is used for switching three power supply sources of the photovoltaic cell, the storage battery and the commercial power interface. The charging control switch is connected with the charging interface and used for controlling the power supply speed. The charging management controller is connected with the charging interface and the power supply change-over switch and is used for controlling the power supply change-over switch and the charging control switch so as to realize the power supply control method of the charging station.
The charging management controller can be realized by a server, can also be applied to a system comprising a terminal and the server, and is realized by interaction of the terminal and the server. The terminal may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.
Specifically, when it is detected that the current vehicle is connected to the charging station, the charging management controller obtains the remaining capacity of the current vehicle and the remaining capacities of other vehicles in the charging station through the charging control switch. The charge management controller determines the charge state of the current vehicle according to the remaining capacity of the current vehicle and the remaining capacities of the other vehicles. And calculating the target charging capacity of the other vehicles according to the residual capacities of the other vehicles. The charging management controller acquires the electric quantity of different types of power supply batteries in the charging station through the power supply changeover switch.
Further, the charge management controller determines a target power supply mode of the current vehicle according to the state of charge of the current vehicle, the target charge capacity of the other vehicle, the capacities of the different types of power supply batteries, and the priorities of the different types of power supply batteries. And the charging management controller controls the charging station to supply power to the current vehicle in a target power supply mode by controlling the power supply changeover switch and the charging control switch.
In one embodiment, as shown in fig. 2, a power supply control method for a charging station is provided, which is described by taking the method as an example applied to the charging management controller in fig. 1, and includes the following steps:
step 202, when it is detected that the current vehicle is connected to the charging station, the remaining electric quantity of the current vehicle is obtained.
Wherein the charging station is a public place for charging the electric vehicle, like a gas station. The electric vehicle can be an electric bicycle, an electric automobile and the like. The current vehicle is a vehicle currently accessed to a charging station and waiting for charging. The remaining amount of power of the current vehicle is the electric quantity value of the current vehicle.
Specifically, the charging management controller is connected with the charging interface through the charging control switch. When the charging interface detects that the vehicle is accessed, the charging control switch is turned on, and the charging management controller can acquire the residual electric quantity of the accessed current vehicle through the charging interface.
And 204, acquiring the residual electric quantity of other vehicles in the charging station, and determining the charging state of the current vehicle according to the residual electric quantity of the current vehicle and the residual electric quantity of the other vehicles.
The other vehicles in the charging station are vehicles which are accessed before the current vehicle is accessed into the charging station, and can be vehicles which are charged, vehicles which are in the process of charging, and vehicles which wait for charging. The remaining amount of electricity of the other vehicle is the amount of electricity of the other vehicle. Specifically, the remaining capacity corresponding to other vehicles when the current vehicle is connected to the charging station may be referred to.
Specifically, as in the method of acquiring the remaining capacity of the current vehicle, the charging management controller may acquire the remaining capacity of other vehicles in the charging station through the charging interface. After obtaining the remaining capacity of the current vehicle and the remaining capacities of other vehicles in the charging station, the charging management controller may determine the charging state of the current vehicle according to the remaining capacity of the current vehicle and the remaining capacities of the other vehicles.
For example, the remaining capacity of the current vehicle and the remaining capacity of the other vehicle are both less than or equal to a preset vehicle capacity threshold, the remaining capacity of the current vehicle and the remaining capacity of the other vehicle are both greater than a preset vehicle capacity threshold, and the like.
And step 206, calculating to obtain the target charging capacity of the other vehicles according to the residual capacities of the other vehicles.
The target charging capacity refers to a charging capacity required by the vehicle.
Specifically, when acquiring the remaining capacity of the other vehicle, the charge management controller may also acquire the battery model of the other vehicle, and determine the charge capacity of the other vehicle according to the battery model of the other vehicle. The charge management controller may obtain the target charge capacity of the other vehicle by subtracting the remaining capacity of the other vehicle from the charge capacity of the other vehicle.
In one embodiment, the charge management controller may also multiply the charge capacity of the other vehicle by a scaling factor and subtract the remaining charge capacity of the other vehicle to obtain the target charge capacity of the other vehicle. For example, the scale factor is set to 90%.
And step 208, acquiring the electric quantity of different types of power supply batteries in the charging station and the priority of the different types of power supply batteries.
Among them, the different types of power supply cells include photovoltaic cells and storage cells. The priority of the different types of supply batteries is determined by the nature of the supply batteries. Compared with a storage battery, the photovoltaic cell is used as a new energy source, can convert light energy into electric energy, saves fuel oil energy and effectively protects the environment. Therefore, when the target power supply is selected, the photovoltaic cell is prioritized over the storage battery.
Specifically, the charge management controller is connected with the power supply batteries of different types through a plurality of power supply change-over switches, and the charge management controller can acquire the electric quantity of the power supply batteries of different types, namely the electric quantity of the photovoltaic battery and the electric quantity of the storage battery, and specifically can be the electric quantity corresponding to the photovoltaic battery and the electric quantity corresponding to the storage battery when the current vehicle is accessed. In addition, the charging management controller also stores the priorities of different types of power supply batteries, and the priorities can be directly obtained by the charging management controller.
And step 210, determining a target power supply mode of the current vehicle according to the charging state of the current vehicle, the target charging electric quantity of other vehicles, the electric quantity of different types of power supply batteries and the priority of the different types of power supply batteries.
Wherein the target power supply mode comprises 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, a power supply suspension, and the like, and the first power supply speed is greater than the second power supply speed. The target power supply comprises a photovoltaic cell, a storage battery and commercial power. When the target power supply is selected, the photovoltaic cell takes precedence over the battery. The use of the mains electricity loads the mains electricity network and therefore the battery has priority over the mains electricity.
Specifically, the charging management controller adds the electric quantities of the different types of power supply batteries, that is, adds the electric quantities of the photovoltaic battery and the storage battery to obtain the total electric quantity of the battery of the charging station. And the charging management controller compares the target charging electric quantity of other vehicles with the total battery electric quantity of the charging station to obtain a comparison result. The charging management controller may determine a target power supply speed corresponding to the current vehicle with respect to the charging state of the current vehicle and the comparison result.
And determining the target power supply of the current vehicle by the charge management controller according to the electric quantity of the different types of power supply batteries and the priority of the different types of power supply batteries by combining the charging state of the current vehicle and the comparison result. For example, when the electric quantity of the photovoltaic cell is greater than or equal to a preset battery electric quantity threshold value, the photovoltaic cell is used as a target power supply source of the current vehicle, and the current vehicle is preferentially powered by the photovoltaic cell.
And step 212, controlling the charging station to supply power for the current vehicle through the target power supply mode.
Specifically, after the target power supply speed and the target power supply of the current vehicle are determined, the charging management controller controls the power output by the charging interface through the charging control switch, and switches the power to the corresponding interface of the target power supply through the power supply changeover switch, so that the charging station is controlled to supply power to the current vehicle through the target power supply speed and the target power supply.
In one embodiment, the charge management controller calculates a target charge capacity of the current vehicle according to the remaining capacity 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 electric quantity of the current vehicle is acquired at intervals, and when the real-time electric quantity of the current vehicle is larger than or equal to the target charging electric quantity of the current vehicle, the charging management controller controls the charging station to stop supplying power to the current vehicle through the charging control switch.
In the power supply control method of the charging station, when the current vehicle is detected to be connected to the charging station, the charging state of the current vehicle is determined according to the residual electric quantity of the current vehicle, the residual electric quantity of other vehicles in the charging station, the electric quantity of different types of power supply batteries and the priorities of the different types of power supply batteries, the target charging electric quantity of the other vehicles is calculated according to the residual electric quantity of the current vehicle and the residual electric quantity of the other vehicles, the target power supply mode of the current vehicle is determined according to the charging state of the current vehicle, the target charging electric quantity of the other vehicles, the electric quantity of the different types of power supply batteries and the priorities of the different types of power supply batteries, the target power supply mode of the current vehicle in different charging states can be determined, and therefore the charging station is controlled to supply power to the current vehicle through the target power supply mode, the load of the commercial power grid is effectively reduced.
In one embodiment, as shown in FIG. 3, step 210 comprises:
step 302, when the residual electric quantity of the current vehicle is larger than a preset vehicle electric quantity threshold value and the residual electric quantities of other vehicles are smaller than or equal to the preset vehicle electric quantity threshold value, calculating the total electric quantity of the battery of the charging station according to the electric quantities of different types of power supply batteries;
step 304, when the total electric quantity of the battery is larger than the target charging electric quantity of other vehicles, acquiring a first power supply speed;
step 306, determining a target power supply of the current vehicle according to the electric quantity of the different types of power supply batteries and the priorities of the different types of power supply batteries;
and 308, combining the first power supply speed and the target power supply to obtain the target power supply mode of the current vehicle.
The preset vehicle electric quantity threshold value refers to a low electric quantity threshold value of the vehicle. When the residual electric quantity of the vehicle is smaller than or equal to the preset vehicle electric quantity threshold value, the situation that the electric quantity of the vehicle is too low is indicated, and charging is urgently needed.
In one embodiment, the preset vehicle charge threshold may be a fixed charge value, such as 100Wh (watt-hours). In other embodiments, the preset vehicle charge threshold may be a proportional value, such as 20% of the charge capacity of the vehicle.
Specifically, the charge management controller compares the remaining capacity of the current vehicle with a preset vehicle capacity threshold. When the residual capacity of the current vehicle is greater than the preset vehicle capacity threshold, the charge management controller compares the residual capacity of other vehicles with the preset vehicle capacity threshold, so as to determine the charge state of the current vehicle. And when the charging state of the current vehicle is that the residual electric quantity of the current vehicle is larger than a preset vehicle electric quantity threshold value and the residual electric quantity of other vehicles is smaller than or equal to the preset vehicle electric quantity threshold value, the charging management controller calculates the total electric quantity of the battery of the charging station according to the electric quantities of the different types of power supply batteries. And the charging management controller compares the total electric quantity of the battery with the target charging electric quantity of other vehicles and judges whether the battery of the charging station has enough electric quantity to supply power for the current vehicle.
In one embodiment, the target power supply mode of the current vehicle is determined to be non-power supply when the total battery charge amount is less than or equal to the target charge amount of the other vehicle.
Specifically, the charge management controller preferentially supplies power to the other vehicle because the remaining capacity of the other vehicle is less than or equal to a preset vehicle capacity threshold. And the total electric quantity of the battery in the charging station is less than or equal to the target charging electric quantity of other vehicles, which indicates that the power supply battery of the charging station does not have enough electric quantity to supply power for the current vehicle. And the residual capacity of the current vehicle is greater than the preset vehicle capacity threshold value, which indicates that the current vehicle is not in a charging emergency, and at the moment, the charging management controller can determine that the target power supply mode of the current vehicle is not power supply, so that the energy is saved, and the load of a commercial power grid is reduced.
In one embodiment, the charge management controller may estimate the remaining range of the current vehicle based on the remaining capacity of the current vehicle after determining that the target power supply mode of the current vehicle is non-power supply. The charging management controller searches other charging stations which can be reached by the current vehicle and are provided with batteries for supplying power to the current vehicle for the current vehicle through the remaining mileage of the current vehicle. Further, the charging management controller acquires the digital map, formulates a driving route for the current vehicle according to the position information of the current charging station and the position information of other charging stations, and sends the driving route and the position information of other charging stations to the current vehicle, so that a user of the current vehicle can select whether to drive to other charging stations for charging.
In one embodiment, when the total battery charge is greater than the target charge of other vehicles, a first power supply speed is acquired, 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 the different output powers correspond to different power supply speeds. The first supply speed is a relatively slow charging speed, corresponding to a small output power.
Specifically, the charge management controller preferentially supplies power to the other vehicle because the remaining capacity of the other vehicle is less than or equal to a preset vehicle capacity threshold. And the total electric quantity of the battery in the charging station is larger than the target charging electric quantity of other vehicles, which indicates that the battery of the charging station has enough electric quantity to supply power for the current vehicle. And the residual capacity of the current vehicle is greater than the preset vehicle capacity threshold value, the charging management controller can use the battery in the charging station to slowly supply power to the current vehicle through smaller output power.
Further, after the first power supply speed is taken as the target power supply speed of the current vehicle, step 306 is entered. Among them, the different types of power supply cells include photovoltaic cells and storage cells. Step 306 includes: when the electric quantity of the photovoltaic cell is larger than or equal to a preset battery electric quantity threshold value, taking the photovoltaic cell as a target power supply of the current vehicle; and when the electric quantity of the photovoltaic cell is smaller than a preset cell electric quantity threshold value, taking the storage battery as a target power supply of the current vehicle.
The preset battery power threshold value is a low power threshold value of the power supply battery, and is the same as the preset vehicle power threshold value, and the preset battery power threshold value can be a fixed power value or a proportional value.
Specifically, when the electric quantity of the photovoltaic cell is greater than or equal to a preset battery electric quantity threshold value, it is indicated that the photovoltaic cell has enough electric quantity to supply power, and at this time, the photovoltaic cell is used as a target power supply of the current vehicle. Since the total battery capacity of the charging station is greater than the target charging capacity of other vehicles, the charging management controller may use the storage battery as the target power supply of the current vehicle when the battery capacity of the photovoltaic battery is less than the preset battery capacity threshold.
In this embodiment, the total battery capacity of the charging station is compared with the target charging capacity of the other vehicle when the remaining capacity of the current vehicle is greater than the preset vehicle capacity threshold and the remaining capacity of the other vehicle is less than or equal to the preset vehicle capacity threshold. When the total electric quantity of the battery is less than or equal to the target charging electric quantity of other vehicles, the current vehicle is not supplied with power, and the load of a commercial power grid can be effectively reduced.

At this time, the charging management controller acquires the second power supply speed, and takes the second power supply speed as the target power supply speed of the current vehicle to realize the rapid charging of the current vehicle.
Further, the charging management controller adds the electric quantities of the different types of power supply batteries to obtain the total electric quantity of the batteries of the charging station. And the charging management controller compares the total electric quantity of the battery with the target charging electric quantity of other vehicles and judges whether the battery of the charging station has enough electric quantity to supply power for the current vehicle.
In one embodiment, when the total battery charge is less than or equal to the target charging charge of the other vehicle, it indicates that the power supply battery of the charging station does not have enough charge to supply power to the current vehicle. The charging management controller is used for connecting the commercial power interface with the charging interface corresponding to the current vehicle by controlling the power supply changeover switch, and controlling the charging interface corresponding to the current vehicle to output power corresponding to the second power supply speed by the charging control switch. And therefore, the charging station is controlled to supply power to the current vehicle through the second power supply speed and the commercial power interface.

and step 504, when the total battery capacity of the charging station is less than or equal to the target charging capacity of other vehicles, determining that the target power supply mode of the current vehicle is not power supply.
Specifically, the charge management controller compares the remaining capacity of the current vehicle with a preset vehicle capacity threshold. When the residual capacity of the current vehicle is greater than the preset vehicle capacity threshold, the charge management controller compares the residual capacity of other vehicles with the preset vehicle capacity threshold, so as to determine the charge state of the current vehicle. And when the charging state of the current vehicle is that the residual electric quantity of the current vehicle is larger than a preset vehicle electric quantity threshold value and the residual electric quantity of other vehicles is larger than a preset vehicle electric quantity threshold value, the current vehicle and the other vehicles are not in urgent charging. At this time, the charging management controller compares the total electric quantity of the battery with the target charging electric quantity of other vehicles, and judges whether the battery of the charging station has enough electric quantity to supply power for the current vehicle.
In one embodiment, the target power supply mode of the current vehicle is determined to be non-power supply when the total battery charge amount is less than or equal to the target charge amount of the other vehicle.
Specifically, the fact that the remaining capacity of the current vehicle is greater than the preset vehicle capacity threshold value and the remaining capacities of the other vehicles are greater than the preset vehicle capacity threshold value indicates that the power supply battery of the charging station does not have enough capacity to supply power to the current vehicle. And the residual capacity of the current vehicle is greater than the preset vehicle capacity threshold value, which indicates that the current vehicle is not in a charging emergency, and at the moment, the charging management controller can determine that the target power supply mode of the current vehicle is not power supply, so that the energy is saved, and the load of a commercial power grid is reduced.
In one embodiment, when the total battery charge is greater than the target charging charge of other vehicles, the target power supply of the current vehicle is determined according to the charge of different types of power supply batteries and the priority of the different types of power supply batteries.

Further, since the remaining capacity of the current vehicle and the remaining capacity of the other vehicles are both greater than the preset vehicle capacity threshold, the charging station can supply power to the current vehicle at the first power supply speed, the second power supply speed or other conventional power supply speeds.
In this embodiment, when the remaining capacity of the current vehicle is greater than the preset vehicle capacity threshold and the remaining capacity of the other vehicle is greater than the preset vehicle capacity threshold, the total battery capacity of the charging station is compared with the target charging capacity of the other vehicle.
