Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the charging method and apparatus for a vehicle provided by the present disclosure, an application scenario related to each embodiment in the present disclosure is first introduced, where a charging cabinet in the application scenario may be a direct current charging cabinet, and a first connecting device and a second connecting device are arranged in the charging cabinet, where the connecting devices may be contactors, and an actuation state and a disconnection state are respectively corresponding to a connection state and a disconnection state. The charging vehicle and the discharging vehicle may be any devices using a power battery as an energy source, and may be, for example, an electric vehicle, such as an electric car, but not limited to a pure electric car or a hybrid car.
Fig. 1 is a flowchart illustrating a charging method for a vehicle, as shown in fig. 1, applied to a charging cabinet, according to an embodiment, the method including:
and 101, when the charging cabinet controls the power grid to discharge to the charging vehicle through the first connecting device, after the discharging gun of the discharging vehicle is confirmed to be connected with the charging cabinet, controlling the second connecting device of the charging cabinet to be connected with the discharging vehicle.
For example, when a charging vehicle needs to be charged through a charging cabinet, a charging gun is connected with the charging cabinet, when the charging gun is connected with the charging cabinet, a charging gun connection signal can be sent to the charging cabinet to indicate the connection state of the charging gun and the charging cabinet, after the charging cabinet receives the charging gun connection signal, a user can control a charging cabinet to control a power grid to discharge to the charging vehicle through a first connection device by opening a discharge switch on the charging cabinet (or through verification modes such as card swiping, coin inserting, code scanning and the like), and as the resistance value of a charging circuit of the charging vehicle meets the charging standard, when the charging signal sent by the charging cabinet is detected, the charging vehicle closes an electric lock and enters the charging state. If the power grid is in the peak period of power utilization, the power utilization pressure is high, the problems of unstable voltage or low power supply capacity and the like exist, and idle vehicles can supply power to the charging vehicles, so that the pressure of the power grid can be relieved while the charging vehicles are charged. The spare vehicle is used as a discharging vehicle, the discharging vehicle connects the discharging gun with the charging cabinet, similarly, a discharging gun connection signal can be sent to the charging cabinet to indicate the connection state of the discharging gun and the charging gun, and the charging cabinet controls a second connecting device of the charging cabinet to be connected with the discharging vehicle after receiving the discharging gun connection signal.
And 102, after the second connecting device is connected with the discharging vehicle, controlling the discharging vehicle to discharge to the charging vehicle through the second connecting device.
For example, after confirming that the second connection device connects the charging cabinet with the discharging vehicle, the discharging vehicle is controlled to discharge electricity to the charging vehicle through the second connection device. The charging cabinet may send a discharge request to the discharging vehicle to instruct the discharging vehicle to discharge. After receiving the discharging request, the BMS of the discharging vehicle (chinese: battery management System) first detects whether the battery of the charging vehicle has a fault and whether the electric quantity of the battery meets the requirement for external discharging (e.g., whether the electric quantity is greater than a preset electric quantity threshold). When the battery is normal and the battery capacity meets the requirement of external discharge, the discharging vehicle discharges to the charging vehicle through the second connecting device. The resistance value of the discharging circuit of the discharging vehicle is different from the resistance value of the charging circuit of the discharging vehicle, and the charging signal and the discharging signal are distinguished, so that the discharging vehicle is switched to a discharging working state after detecting a discharging request sent by the charging cabinet, and at the moment, the discharging switch of the discharging vehicle is controlled to be opened, and the BMS controls the contactor in the electric box to be closed, so that the battery starts to discharge.
And 103, controlling the first connecting device to be disconnected from the charging vehicle.
For example, after the second connection device is connected with the discharging vehicle, the first connection device still keeps being connected with the charging vehicle, so that the continuity of the charging process of the charging vehicle is ensured, and after the discharging vehicle is controlled to discharge to the charging vehicle through the second connection device, the first connection device is controlled to be disconnected from the charging vehicle.
It should be noted that, while the discharging gun is connected to the charging cabinet, the identity of the discharging vehicle can be confirmed by a verification method such as a switch, a card swiping method or a code scanning method preset on the charging cabinet, so that the charging cabinet measures the charging amount of the discharging vehicle as the charging vehicle, and the charging vehicle can pay for the discharging vehicle after charging.
In conclusion, according to the charging cabinet, in the process that the charging cabinet discharges to the charging vehicle through the first connecting device, the discharging gun of the discharging vehicle is detected to be connected with the charging cabinet, the second connecting device is used for connecting the charging cabinet with the discharging vehicle, then the discharging vehicle is controlled to discharge to the charging vehicle through the second connecting device, and finally the first connecting device is controlled to be disconnected from the charging vehicle, so that the charging cabinet is used for charging the vehicle, the utilization rate of electric energy can be improved, and the power supply pressure of a power grid is reduced.
FIG. 2 is a flow chart illustrating another charging method for a vehicle, according to an exemplary embodiment, as shown in FIG. 2, step 102 includes:
step 1021, determining whether the current power grid is in a peak power utilization state.
And step 1022, when the current power grid is in the peak power utilization state, controlling the discharging vehicle to discharge to the charging vehicle through the second connecting device.
And step 1023, when the current power grid is not in the peak power utilization state, controlling the power grid to discharge to the charging vehicle through the first connecting device.
For example, the charging cabinet can control the power grid to charge the charging vehicle and can also control the discharging vehicle to charge the charging vehicle, so that the selection strategy of charging the charging vehicle by the power grid or the discharging vehicle can be determined according to whether the current state of the power grid is the peak power utilization state or not. When the current power grid is in the power utilization peak state and the discharging vehicle is connected with the charging cabinet, the discharging vehicle is controlled to discharge to the charging vehicle through the second connecting device, and when the current power grid is not in the power utilization peak state (or the discharging vehicle does not exist), the power grid is controlled to discharge to the charging vehicle through the first connecting device. The current state of the power grid can be determined by monitoring the voltage value of the power grid and/or the load of the power grid in real time, and several fixed time intervals can be determined as peak time periods of power utilization in advance. For example, when the voltage value of the power grid is lower than a preset voltage threshold, it is determined that the current power grid is in the peak power utilization state, or when the load of the power grid is greater than a preset load threshold, it is determined that the current power grid is in the peak power utilization state, two time periods from 12 pm to 1 pm and from 7 pm to 10 pm may be set as the peak power utilization periods, and the charging vehicle is charged in the two time periods, so as to determine that the current power grid is in the peak power utilization state. The preset voltage threshold, the load threshold and the peak time period of power consumption can be flexibly adjusted according to actual demands, for example, the peak time periods of power consumption in summer and winter can be properly prolonged compared with spring and autumn according to seasons. Thereby relieving the pressure of peak electricity utilization. Further, the selection strategy can also be that as long as the discharging vehicle exists, the discharging vehicle is preferentially selected to discharge, so that the electric energy of the idle vehicle can be fully utilized, and the vehicle owner of the idle vehicle is created.
FIG. 3 is a flow chart illustrating another charging method for a vehicle according to an exemplary embodiment, as shown in FIG. 3, further comprising:
and 104, controlling the discharging vehicle to stop discharging after the charging vehicle is determined to be fully charged.
And 105, controlling the second connecting device to be disconnected from the discharging vehicle.
For example, when the charging vehicle is fully charged, a stop discharge request may be sent to the charging cabinet to instruct the charging cabinet to stop discharging. The charging cabinet can send a discharging stopping instruction to the discharging vehicle after receiving the discharging stopping request, and the discharging vehicle stops discharging after receiving the discharging stopping instruction. And then the second connecting device is controlled to be disconnected with the discharging vehicle, so that the whole charging process is completed. The charging vehicle may be charged at this time according to the amount of electricity discharged from the discharging vehicle and a preset charging standard.
FIG. 4 is a flow chart illustrating another charging method for a vehicle, according to an exemplary embodiment, as shown in FIG. 4, further comprising:
and 106, when the electric quantity of the discharging vehicle is determined to be smaller than the preset electric quantity threshold value, controlling the first connecting device to be connected with the charging vehicle, and controlling the second connecting device to be disconnected with the discharging vehicle.
Step 107, the grid is controlled to discharge to the charging vehicle via the first connection means.
And step 108, after the fact that the charging vehicle is fully charged is determined, the first connecting device is controlled to be disconnected with the charging vehicle.
For example, in order to ensure the cruising ability of the discharging vehicle itself, a charge amount threshold value may be set in advance, and when the charge amount of the discharging vehicle is less than the charge amount threshold value, the discharging vehicle does not discharge electricity to the charging vehicle. Namely, the BMS of the charging vehicle monitors the remaining capacity (SOC) of the battery in real time, and when the remaining capacity is less than a preset capacity threshold (which may be set to 20%, for example), sends a discharging stop command to the charging cabinet to inform the charging cabinet that the discharging vehicle is about to stop discharging, and controls the discharging vehicle to stop discharging. After receiving the discharge stopping instruction, the charging cabinet firstly controls the first connecting device to be connected with the charging vehicle so as to ensure the continuity of the charging process of the charging vehicle, and then controls the second connecting device to be disconnected with the discharging vehicle. And then the charging cabinet controls the power grid to discharge to the charging vehicle through the first connecting device, and after the charging vehicle is fully charged, the first connecting device is controlled to be disconnected with the charging vehicle, so that the whole charging process is completed.
Fig. 5 is a flowchart illustrating another charging method for a vehicle according to an exemplary embodiment, as shown in fig. 5, step 101 includes:
in step 1011, whether the first connecting device and the charging vehicle are normally connected is detected.
And step 1012, controlling the second connecting device of the charging cabinet to be connected with the discharging vehicle when the first connecting device is normally connected with the charging vehicle.
And step 1013, when the first connecting device is abnormally connected with the charging vehicle, sending discharge prohibition information, wherein the discharge prohibition information is used for indicating that the current charging cabinet is in a discharge prohibition state.
For example, after receiving the signal of connecting the discharging gun, the charging cabinet detects whether the first connecting device is normally connected to the charging vehicle, that is, detects whether the current charging cabinet can normally charge the charging vehicle. Under the condition that the first connecting device is normally connected with the charging vehicle, the second connecting device of the charging cabinet is controlled to be connected with the discharging vehicle, when the first connecting device is detected to be abnormally connected with the charging vehicle, the charging cabinet is correspondingly probably abnormal, or the first connecting device is not normally connected with the charging vehicle, the current state that the charging cabinet is in a discharging prohibition state is shown, at the moment, discharging prohibition information can be sent, and the discharging prohibition information can be displayed through a loudspeaker, an indicator lamp or a display module in a sound, light or image information mode.
FIG. 6 is a flow chart illustrating another charging method for a vehicle, according to an exemplary embodiment, as shown in FIG. 6, prior to step 101, the method further comprising:
step 109, detecting the state of the charging cabinet.
And step 110, controlling the charging cabinet to control the power grid to discharge to the charging vehicle through the first connecting device when the charging cabinet is in a normal state.
And step 111, when the charging cabinet is in an abnormal state, sending fault information, wherein the fault information is used for indicating that the current charging cabinet has a fault and cannot discharge.
For example, after a charging gun of a charging vehicle is connected with a charging cabinet, the charging cabinet may perform self-checking to detect a current state of the charging cabinet, when the charging cabinet is in a normal state, it indicates that the charging cabinet can control a power grid to normally discharge the charging vehicle, when the charging cabinet is in an abnormal state, it indicates that the charging cabinet cannot normally operate, and at this time, fault information may be sent, and similarly, the fault information may be displayed in a mode of sound, light, or image information through a speaker, an indicator light, or a display module.
It should be noted that, as shown in fig. 7, the charging cabinet structure described in this disclosure includes a first connector, a second connector, and a charging controller, where the charging controller is connected to the first connector and the second connector respectively, the first connector is used to connect the charging cabinet to the charging vehicle, and the second connector is used to connect the charging cabinet to the discharging vehicle. The charging controller is configured to execute steps executed in any one of the charging methods for a vehicle shown in fig. 1 to 6 described above. And a direct current meter is also connected between the charging controller and the first connector and used for measuring the electric quantity charged to the charging vehicle by the power grid. Still be connected with three-phase ammeter and lightning protection device between charge controller and the second connector for measure the discharge capacity of the vehicle that discharges, and guarantee that the vehicle that discharges can discharge safely. The charging controller is connected with the switching power supply module, the switching power supply module is connected with the controller in the charging cabinet, and the controller is used for controlling modules such as an operation panel of the charging cabinet (such as a touch screen, a card swiping module, a communication module, a three-phase electric meter, mode control, an indicator light, a direct current electric meter, signal display, charging display and the like).
In conclusion, according to the charging cabinet, in the process that the charging cabinet discharges to the charging vehicle through the first connecting device, the discharging gun of the discharging vehicle is detected to be connected with the charging cabinet, the second connecting device is used for connecting the charging cabinet with the discharging vehicle, then the discharging vehicle is controlled to discharge to the charging vehicle through the second connecting device, and finally the first connecting device is controlled to be disconnected from the charging vehicle, so that the charging cabinet is used for charging the vehicle, the utilization rate of electric energy can be improved, and the power supply pressure of a power grid is reduced.
