In one embodiment, as shown in fig. 2, a power supply control method is provided, which is described by taking the method as an example applied to the microgrid controller in fig. 1, and includes the following steps:
step 202, when the state of the electric energy storage for supplying power to the charging pile is in a state of not being full and an electric vehicle discharging instruction sent by the terminal is received, sending a reverse charging instruction to the charging pile specified by the electric vehicle discharging instruction so as to control the charging pile to reversely charge from the connected electric vehicle.
Specifically, after a charging gun of the charging pile is connected with the electric vehicle, the terminal scans a graphic code on the charging gun through charging software, a discharging instruction of the electric vehicle discharging to the charging pile is generated according to the scanned graphic code, and meanwhile, an electric energy storage device used for supplying power to the charging pile in the charging station does not store full electric quantity; the terminal transmits the generated electric vehicle discharging instruction to the microgrid controller through a network, and the microgrid controller sends a reverse charging instruction to a charging pile specified by the electric vehicle discharging instruction so as to control the charging pile to perform reverse charging from the connected electric vehicle. The graphic code may be a two-dimensional code or a bar code.
The state of the electric energy storage refers to the electric quantity condition of an electric energy storage device used for supplying power to the charging pile in the charging station, and the state of the electric energy storage can be a full state and a non-full state. For example, the state of the electrical energy storage is in a full state, which indicates that the electrical energy storage device is fully charged. The state of the electric energy storage is in a state of not full, which indicates that the electric energy storage device does not completely store electric quantity, and the residual space continues to store electric quantity.
The electric vehicle discharging instruction refers to an instruction that the electric vehicle transmits electric energy stored by the electric vehicle to the charging pile; the discharging instruction comprises an electric vehicle identification and a charging gun identification of a charging pile connected with the electric vehicle. The reverse charging means that the electric vehicle charges the charging pile through a charging gun connected with the electric vehicle.
And step 204, monitoring the residual electric quantity of the electric vehicle.
Specifically, begin to establish the connection when the electric motor car with fill electric pile, the electric quantity of this electric motor car self is monitored to the microgrid controller to this residual capacity of real time monitoring electric motor car prevents that the residual capacity of electric motor car from crossing the performance that influences the electric motor car excessively. The controller in the electric pile is filled to the accessible monitors the electric quantity of the electric motor car self that connects to can show in real time that it carries out the electric quantity that the reverse charging was acquireed and the residual capacity of electric motor car to fill the electric pile.
The State of Charge (SOC) refers to the current State of the electric power stored in the electric vehicle. The representation of the remaining capacity may be a percentage of the currently stored capacity to the full capacity, such as 20% of the remaining capacity. The remaining capacity can also be directly expressed by the currently stored capacity, for example, the remaining capacity is 20KW · h.
And step 206, when the residual electric quantity is reduced to the early warning threshold value, a reverse charging stopping instruction is sent to the charging pile so as to control the charging pile to stop reverse charging from the electric vehicle.
Specifically, along with filling the going on of the reverse charging process of electric pile, the residual capacity of electric motor car can slowly reduce, when the residual capacity drops to the early warning threshold value, the microgrid controller sends the reverse stop instruction that charges to the electric pile of filling of being connected with the electric motor car, controls through this instruction to fill electric pile and stops to charge from the electric motor car reverse. Optionally, when the residual capacity drops to the early warning threshold value, fill electric pile and can pass through the discharge demand that the sound suggestion user has reached the electric motor car, also can show the residual capacity of electric motor car apart from the early warning threshold value on filling electric pile in real time simultaneously, should fill the required surplus reverse charge time of electric pile.
The early warning threshold value is the minimum electric quantity required by the electric vehicle for maintaining a normal state, normally running and not influencing the performance of the electric vehicle. Such as setting the pre-alarm threshold to 20%. The early warning threshold value can also be set according to user self-definition, for example, if the user wants to reserve 50% of the electric quantity of the electric vehicle, the early warning threshold value is set to be 50%.
In this embodiment, when the state of the electric energy storage for supplying power to the charging pile is in a state of not being full and the electric vehicle discharging instruction sent by the terminal is received, the charging instruction is sent to the specified charging pile according to the electric vehicle discharging instruction so as to execute the electric vehicle reverse charging connected with the charging pile, the electric energy storage, the terminal and the interaction information of the charging pile are used for controlling the electric vehicle to discharge, so that the charging pile reverse charging connected with the electric vehicle is controlled, and the electric energy stored by the electric vehicle is effectively utilized. Furthermore, through monitoring the residual capacity of the electric vehicle, the charging pile is controlled to stop reverse charging from the electric vehicle, electric energy can be more reasonably scheduled, and the utilization rate of electric resources is improved.
In one embodiment, when the state of the electric energy storage for supplying power to the charging pile is in a non-full state and an electric vehicle discharging instruction sent by a terminal is received, a reverse charging instruction is sent to the charging pile specified by the electric vehicle discharging instruction, and the method comprises the following steps: when the state of the electric energy storage for supplying power to the charging pile is in a not-full state and the electric vehicle discharging instructions sent by the first number of terminals are received, determining the total amount to be discharged according to the current state of the electric energy storage; acquiring dischargeable quantity of electric vehicles corresponding to the first number of terminals; screening electric vehicle discharging instructions allowed to be executed from the first number of electric vehicle discharging instructions according to the total amount to be discharged and the dischargeable amount; and sending a reverse charging instruction to a charging pile specified by the electric vehicle discharging instruction permitted to be executed.
Specifically, when the charging station has a plurality of electric vehicles to apply for discharging, reasonable and orderly electric vehicle discharging operation can be realized through the embodiment. When the state of the electric energy storage for supplying power to the charging pile is in a not-full state and the microgrid controller receives electric vehicle discharging instructions sent by a first number of terminals, wherein the first number is greater than 1; and determining the total amount to be discharged of the electric vehicles corresponding to the first number of terminals according to the current state of the electric energy storage in the charging station, namely subtracting the electric quantity when the state of the electric energy storage is the full state from the electric quantity of the current state of the electric energy storage, so as to obtain the difference value of the electric quantity and the electric quantity, namely the total amount to be discharged. Each terminal calculates the dischargeable quantity of the electric vehicle according to the discharge performance parameters of the electric vehicle; and screening the electric vehicle discharging instructions permitted to be executed according to the obtained total amount to be discharged and the dischargeable amount of the corresponding electric vehicle of each terminal, and sorting the dischargeable amounts of the corresponding electric vehicles through each terminal so as to screen the electric vehicles executing the electric vehicle discharging instructions. The executed electric vehicle discharging instruction can be screened by the fact that the dischargeable quantity of the electric vehicle corresponding to each terminal is within a given threshold range.
The total amount to be discharged is the difference between the electric quantity when the state of the electric energy storage in the charging station is the full state and the electric quantity when the state of the electric energy storage is the current state.
In this embodiment, when a plurality of electric vehicles apply for discharging at the charging station, the total amount to be discharged is determined according to the state of the electric energy storage for supplying power to the charging pile, the dischargeable amount of the electric vehicle corresponding to each terminal is obtained, and the corresponding electric vehicle execution electric vehicle discharge instruction is screened according to the total amount to be discharged and the dischargeable amount of the electric vehicle. When having realized having a plurality of electric vehicles to apply for discharging in the charging station through this embodiment, can be rationally orderly implement the operation of discharging to the electric motor car.
In one embodiment, the method for screening the electric vehicle discharging commands allowed to be executed from the first number of electric vehicle discharging commands according to the total amount to be discharged and the dischargeable amount comprises the following steps: acquiring discharge performance parameters of electric vehicles corresponding to the first number of terminals; determining the respective estimated discharge time of each electric vehicle according to the discharge performance parameters; determining the discharging priority order of each electric vehicle according to the ascending order of the estimated discharging time; and screening electric vehicle discharging instructions allowed to be executed from the electric vehicle discharging instructions of the first number according to the discharging priority sequence and the total amount to be discharged and the dischargeable amount.
Specifically, the microgrid controller establishes network connection with the terminals, and acquires discharge performance parameters of the electric vehicle corresponding to each of the plurality of terminals through the network connection, wherein the discharge performance parameters of the electric vehicle can be stored on the corresponding terminal or directly input to the corresponding terminal, and the discharge performance parameters include the remaining capacity of the electric vehicle and the maximum accessible current of the charging gun (the parameters have almost no influence on the electric vehicle discharge and can be ignored generally). The microgrid controller determines respective estimated discharge duration of each electric vehicle according to the obtained discharge performance parameters; the estimated discharge time can be calculated through the terminal, namely the terminal acquires the power of a charging pile corresponding to the electric vehicle from the microgrid controller after acquiring the discharge performance parameter of the corresponding electric vehicle, and the estimated discharge time is calculated according to the discharge performance parameter and the power of the charging pile. And the microgrid controller sorts the calculated estimated discharge time lengths of all the electric vehicles according to an ascending order, so as to determine the discharge priority order of each electric vehicle, namely the estimated discharge time lengths of the electric vehicles are sorted into the discharge priority order of the electric vehicles. For example, the electric vehicle with the shorter estimated discharge time period has a higher discharge priority, and the electric vehicle is preferentially permitted to execute the electric vehicle discharge command. And the microgrid controller determines the electric vehicles required by the current charging station to discharge according to the obtained total amount to be discharged of the charging stations and the dischargeable amount corresponding to each electric vehicle, and selects the electric vehicles required by the current charging stations from high to low in the discharging priority order to permit the electric vehicle discharging instruction to be executed after the electric vehicles required by the required number are determined.
Optionally, the estimated discharge time is related to performance parameters of the electric vehicle and the power of the charging pile, and since the battery voltage of the electric vehicle continuously rises in the charging process, when the remaining capacity of the electric vehicle is in a certain stage (for example, the SOC is 20% to 95%), the electric vehicle is reversely charged with the maximum power (rated power of the charging pile) of the charging pile, and the estimated discharge time is the remaining capacity of the electric vehicle divided by the rated power of the charging pile; when the SOC is higher than 95% or lower than 20%, the power of the charging pile can be reduced, and the estimated discharge time length of the electric vehicle is long.
For example, when the battery energy of the taxi biedi E6 is 60KW · h and the rated power of the charging pile connected to the electric vehicle is 50KW, the estimated discharge time of the electric vehicle is 60KW · h/50KW, that is, the estimated discharge time is 1.2 h. However, the estimated discharge time exceeds 1.2h because the battery of the electric vehicle is influenced by the residual capacity.
In the embodiment, when a plurality of electric vehicles discharge at the charging station, the estimated discharge time length is determined according to the discharge performance parameters of each electric vehicle, so that the discharge priority order of the electric vehicles is determined, and the electric vehicles permitted to execute the electric vehicle discharge command are screened according to the discharge priority order.
In one embodiment, the method further comprises the steps of: receiving an electric vehicle charging instruction sent by a terminal; acquiring a charging gun identifier appointed by an electric vehicle charging instruction; and sending a charging command to the charging pile corresponding to the charging gun identifier so as to control the corresponding charging pile to charge the connected electric vehicle through the charging gun corresponding to the charging gun identifier.
Specifically, when the electric vehicle is charged, a charging gun on the charging pile is connected with the electric vehicle, graphic codes on the charging gun are scanned by charging software of a corresponding terminal, and an electric vehicle charging instruction for charging the charging pile is generated according to the graphic codes obtained through scanning. The terminal transmits an electric vehicle charging instruction to the microgrid controller through a network, and the microgrid controller acquires a charging gun identifier specified by the electric vehicle charging instruction; and the microgrid controller sends a charging command to the charging pile corresponding to the charging gun identifier, and controls the corresponding charging pile to charge the connected electric vehicle through the charging gun corresponding to the charging gun identifier according to the charging command.
The electric vehicle charging instruction refers to an instruction for transmitting the electric quantity of the electric energy storage device in the charging station to the electric vehicle through the charging pile, and the electric vehicle charging instruction comprises an electric vehicle identifier and a charging gun identifier of the charging pile connected with the electric vehicle. The charging gun identifier is a mark different from each charging gun and corresponds to the charging gun one to one. The charging command is a charging instruction sent by the microgrid controller to the charging pile, and indicates the charging pile to charge the connected electric vehicle through the charging gun.
In the embodiment, an electric vehicle charging instruction is triggered according to a terminal corresponding to an electric vehicle, wherein the charging instruction comprises a charging gun identifier; and the microgrid controller sends a charging command to the charging pile corresponding to the charging gun identifier, and controls the charging pile to charge the connected electric vehicle through the charging gun corresponding to the charging gun identifier according to the charging command. The electric vehicle provided by the implementation can not only perform discharging operation, but also charge the connected electric vehicle through the charging gun corresponding to the charging gun identification.
In one embodiment, the electric vehicle discharge command is triggered during a peak utility power condition, the method further comprising the steps of: when the electric vehicle is in a commercial power consumption peak state, the electric vehicle is charged in sequence according to the sequence of stored energy electricity, new energy electricity and commercial power; the new energy power comprises at least one of wind power and photovoltaic power; when the electric vehicle is in a low-valley state of commercial power, the commercial power is directly adopted for charging the electric vehicle.
Specifically, since the utility power price is positively correlated with the power consumption, when the utility power consumption is in a peak state, the utility power price is relatively high, and thus the terminal corresponding to the electric vehicle triggers the electric vehicle discharge instruction. When the power consumption of the commercial power is in a peak state, the electric vehicle performs discharging operation, a charging gun on a charging pile is connected with the electric vehicle, the charging software corresponding to the terminal is used for scanning the graphic code on the charging pile, a discharging instruction of the electric vehicle discharging to the charging pile is generated according to the scanned graphic code, and meanwhile, the state of the electric energy storage used for supplying power to the charging pile is in a not-full state. And the microgrid controller sends a reverse charging instruction according to the charging pile appointed by the obtained electric vehicle discharging instruction, so that the charging pile is controlled to perform reverse charging from the connected electric vehicle.
The electric motor car charges triggering of instruction can trigger at any time according to the demand of electric motor car, and when being in commercial power consumption peak state, the terminal that the electric motor car corresponds sends the electric motor car instruction of charging to the microgrid controller, and the electric pile that the request corresponds with the rifle identification that charges to the electric motor car of being connected with the rifle that charges. The microgrid controller sequentially charges the electric vehicle requesting the electric vehicle charging instruction according to the sequence of the stored energy electricity, the new energy electricity and the commercial power, and generates a charging pile appointed by the electric vehicle according to the charging sequence and the electric vehicle charging instruction to send a reverse charging instruction to control the charging pile to reversely charge the connected electric vehicle. The charging sequence is that firstly, the electric vehicle is charged by using the stored energy electricity, if the stored energy is insufficient or not, the new energy electricity is started, and further, if the new energy electricity is insufficient or not, the electric vehicle is charged by using commercial power. Wherein the new energy electricity comprises at least one of wind power and photovoltaic electricity. When being in commercial power consumption valley state, the microgrid controller directly provides the commercial power and charges to the electric motor car of request electric motor car charging instruction, and the order of charging that reverse charging instruction carried this moment only charges according to the commercial power to the electric motor car.
For example, when the electric vehicle is in a peak state of the commercial power consumption, a certain electric vehicle sends an electric vehicle discharging instruction through a corresponding terminal and transmits the electric vehicle discharging instruction to the microgrid controller through the network, the microgrid controller inquires whether energy storage electricity exists according to the received electric vehicle discharging instruction, and if the energy storage electricity exists and meets the required charging electric quantity of the electric vehicle, the energy storage electricity is transmitted to the electric vehicle connected with the charging gun through the charging pile corresponding to the charging gun identifier; if the stored energy electricity is insufficient, the new energy electricity is used as supplementary electricity and is transmitted to the electric vehicle for charging; and if no new energy is available, the commercial power is transmitted to the electric vehicle for charging.
The peak state of the utility power consumption means that the utility power consumption situation in a region is in a peak state within a certain period of time, and the utility power price at the time is relatively high within the period of time. Compared with the peak state of the commercial power consumption, the corresponding valley state of the commercial power means that the commercial power consumption condition of an area is in a valley state within a certain period of time, and the commercial power price is relatively low at the moment.
In the embodiment, a charging and discharging instruction of the electric vehicle is triggered respectively according to the power consumption condition of the commercial power, and a discharging instruction of the electric vehicle is triggered in the peak state of the commercial power consumption; the charging instruction of the electric vehicle can be triggered at any time, but the types of electric quantity for charging the electric vehicle are different according to the electricity consumption condition of the commercial power, and when the commercial power is in an electricity consumption peak state, the electric vehicle is charged in sequence according to the sequence of the stored energy electricity, the new energy electricity and the commercial power; when the electric vehicle is in a low-valley state of commercial power, the electric vehicle is directly charged by the commercial power. The embodiment realizes the quick switching of energy storage, new energy and commercial power, and improves the economy of electricity consumption of the charging station.
