Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Embodiments of the present application are set forth in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof.
With the development of economy and the improvement of living standard of people, on one hand, electronic terminals such as mobile phones, flat panels and the like play more and more important roles in daily life of people; on the other hand, the demand for environmental protection is increasingly outstanding, and electric devices powered by electric energy, such as hybrid vehicles, electric vehicles, and electric bicycles, appear. In both electronic terminal equipment and electric equipment, due to the limited capacity of the battery, the battery needs to be charged in time during use. The charging control method, the charging control device and the charging pile can be applied to public places with relatively concentrated charging demands, such as markets, hospitals, stations, charging stations and the like, and are suitable for various charging modes, such as direct-current quick charging, alternating-current slow charging and the like, so that the charging demands of users are met.
In one embodiment, referring to fig. 1, a charging control method is provided, which includes steps S100, S300, S400 and S500.
Step S100: when a charging request of the equipment to be charged is received, whether the residual output power of the charging pile reaches the required power of the equipment to be charged is detected.
Specifically, a charging pile corresponds and has a plurality of charging positions, and every charging position is provided with charging line or rifle that charges respectively. It can be understood that, the charging of the device to be charged means that the device to be charged is electrically connected to a charging line or a charging gun provided on the charging point. Taking a charging pile for charging an electric automobile as an example, the electric automobile is connected to a charging position, namely the electric automobile is stopped at a parking space corresponding to the charging position and is connected to a charging gun. It should be noted that, in the present application, the device to be charged may be an electronic terminal such as a mobile phone and a tablet, or an electric device such as an electric vehicle and an electric bicycle, and for convenience of understanding, the following description will be given by taking the device to be charged as an electric vehicle. The charging request of the device to be charged refers to a charging request sent by the device to be charged, wherein the electric quantity of the newly accessed charging potential is lower than the charging alarm threshold value. Specifically, after the charging device is connected to the charging position, the controller can acquire the electric quantity of the charging device and judge whether the electric quantity is lower than a charging alarm threshold value, wherein the charging alarm threshold value can be an alarm threshold value of the charging device itself or a self-defined numerical value of the charging pile controller. The present embodiment does not limit the specific value of the charging alarm threshold. After the charging equipment is connected to the charging potential, a user can submit a charging request through the intelligent terminal; an automatic switch can be arranged on the charging position, and the switch is automatically closed after the charging equipment is connected and sends a charging request to a controller of the charging pile. In short, the present embodiment does not limit the specific transmission and reception manner of the charging request.
The remaining output power of the charging pile is the difference between the sum of the output power of each charging position of the current charging pile supplying power and the preset rated power of the charging pile. Taking an electric vehicle as an example, the charging machines of different electric vehicles have different power, for example, there are two versions of charging machines of 3.3kW and 7 kW. The output power of the charging potential corresponds to the power of a charger of the charging equipment on the charging potential, for example, the rated power of the charging potential is 7kW, and if the power of the charger of the charging equipment on the charging potential is 3.3kW, the output power of the charging potential is 3.3 kW. That is, there may be a case where the output powers of the respective charging guns are not equal at the time of actual charging. Specifically, after the device to be charged is connected to the charging potential, the controller may obtain the required power of the device to be charged. Meanwhile, the controller can calculate the output power of the current charging pile according to the output power of each charging position, and detect whether the residual output power of the charging pile reaches the required power of the equipment to be charged.
Step S300: when the residual output power of the charging pile does not reach the required power of the equipment to be charged, whether the electric quantity of the charging equipment reaches a preset electric quantity threshold value is judged.
The charging device refers to a device which is currently connected to a charging potential and is charging. The preset electric quantity threshold value is lower than the battery capacity of the charging equipment and higher than the critical value of the emergency power supply requirement of the equipment. When the electric quantity of the equipment reaches the preset electric quantity threshold value, certain duration or mileage can be maintained. Taking an electric vehicle as an example, according to the average operating power of the electric vehicle, the electric quantity required to maintain a specific endurance mileage can be calculated, for example, the electric quantity corresponding to the endurance mileage of 10 km, 20 km, or 30 km can be used as a preset electric quantity threshold. In short, the present embodiment does not limit the specific value of the preset electric quantity threshold.
Further, predetermine the electric quantity threshold value and can include a plurality of numerical values, continue to use electric automobile as an example, fill electric pile's busy condition at present, can set up different predetermine electric quantity threshold values. For example, when there are a large number of cars to be charged connected to the charging potential, the electric quantity corresponding to 10 km of sustained driving can be used as the preset electric quantity threshold; when a large number of cars to be charged are connected to the charging potential, the electric quantity corresponding to the duration of 30 kilometers can be used as the preset electric quantity threshold. It can be understood that, according to the actual situation, more than two different preset electric quantity thresholds may also be set correspondingly, which is not described herein again.
As described above, when the remaining output power of the charging pile does not reach the required power of the device to be charged, the current state cannot directly supply power to the device to be charged, at this time, it is determined whether the electric quantity of the charging device reaches the preset electric quantity threshold, and when it is detected that the electric quantity of the charging device reaches the preset electric quantity threshold, step S400 and step S500 are executed.
Step S400: the power supply to the charging device is stopped.
Step S500: and supplying power to the equipment to be charged.
Specifically, when it is detected that the electric quantity of one charging device reaches a preset electric quantity threshold value and a charging request of a device to be charged is received, whether the sum of the residual output power of the current charging pile and the charging power of the charging device reaches the required power of the device to be charged is judged according to the residual output power of the current charging pile and the charging power of the charging device. If so, stopping supplying power to the charging equipment and supplying power to the equipment to be charged; if not, continuing to wait for the current of other charging equipment to reach the preset electric quantity threshold value. When the fact that the electric quantity of the plurality of charging devices reaches a preset electric quantity threshold value is detected, sorting is carried out according to the ratio of the electric quantity of the charging devices to the capacity of the battery, preferably, the power supply of the charging devices to be fully charged is stopped, and the power supply of the charging devices to be charged is carried out. When a plurality of devices to be charged exist, the devices with the required power smaller than the residual output power of the charging pile are preferentially supplied with power. And if a plurality of devices to be charged with the required power smaller than the residual output power of the charging pile exist, power is supplied according to the sequence of the queuing time of the devices.
According to the charging control method, when a charging request of the device to be charged is received, whether the residual output power of the charging pile reaches the required power of the device to be charged is detected, and when the residual output power of the charging pile does not reach the required power of the device to be charged, whether the charging device reaching a preset electric quantity threshold value exists is judged, wherein the preset electric quantity threshold value is lower than the battery capacity of the charging device. If the charging equipment reaches the preset electric quantity threshold value, the charging equipment is stopped to be powered, the charging equipment to be charged is powered more urgently according to the electric quantity demand, on the premise that the preset rated power of the charging pile is not exceeded, more equipment can be timely powered up in a limited time, and the charging equipment is more scientific.
In an embodiment, referring to fig. 2, after step S100, the method further includes: and when the residual output power of the charging pile reaches the required power of the equipment to be charged, executing the step S500.
Step S500: and supplying power to the equipment to be charged.
Specifically, when the residual output power of the charging pile reaches the required power of the equipment to be charged, the output power surplus of the charging pile at the moment is shown, the charging requirement of the equipment to be charged can be met, and at the moment, the controller controls the charging pile to directly supply power to the equipment to be charged.
In the above embodiment, when the remaining output power who fills electric pile satisfies the demand power of treating the battery charging outfit, directly to treating the battery charging outfit power supply, be favorable to improving the utilization ratio of filling electric pile, improve charge efficiency.
In one embodiment, before step S300, step S200 is further included: the method comprises the steps of obtaining the battery capacity of the charging equipment, and determining a preset electric quantity threshold according to the battery capacity. It is understood that step S200 may be performed before step S100, after step S100, or simultaneously with step S100.
Specifically, the controller may obtain the battery capacity of the device to be charged when the device to be charged is connected to the charging potential, and correspond the battery capacity to the device to be charged, and after the device to be charged starts to be charged, the state of the device to be charged is updated to the charging device, and at this time, the battery capacity of the charging device may be obtained by directly reading the corresponding battery capacity. In addition, the controller may acquire the battery capacity of the charging device after the power supply to the charging device is started. As mentioned above, the preset electric quantity threshold is lower than the battery capacity of the charging device and higher than the critical value of the emergency power supply requirement of the device. When the electric quantity of the equipment reaches the preset electric quantity threshold value, certain duration or mileage can be maintained. Specifically, the preset charge threshold may be expressed by a percentage and represents a ratio of a remaining charge of the battery to a capacity of the battery, for example, the preset charge threshold may be 40%, 60%, or 80% of the capacity of the battery. The preset electric quantity threshold value can also be represented by a specific electric quantity value. In short, the present embodiment does not limit the specific form and the magnitude of the preset electric quantity threshold.
Further, taking a preset electric quantity threshold value represented by a percentage as an example, the preset electric quantity threshold value may not be unique, and taking an electric vehicle as an example, the controller may set different preset electric quantity threshold values according to the type of the charging vehicle. Like plug-in hybrid and pure electric vehicles, their battery capacities are differentiated: the battery capacity of the plug-in hybrid vehicle is small, so the preset electric quantity threshold value should be relatively large; the battery capacity of the pure electric vehicle is large, and then the preset electric quantity threshold value can be relatively small.
Furthermore, different preset electric quantity thresholds can be set according to the current busy situation of the charging pile. Taking an electric automobile as an example, when a large number of automobiles to be charged are connected to a charging potential, 40% of the electric quantity of an automobile battery can be used as a preset electric quantity threshold value; when the number of the cars to be charged connected to the charging potential is large, 60% of the electric quantity of the car battery can be used as a preset electric quantity threshold value. It can be understood that, according to the actual situation, more than two different preset electric quantity thresholds may also be set correspondingly, which is not described herein again.
In the above embodiment, the battery capacity of the charging device is obtained, the preset electric quantity threshold value is determined according to the battery capacity, and the staged charging setting can be performed according to the actual operation condition of the charging pile, so that the power consumption requirement of a single device is met, and as many devices as possible can be charged in a limited time.
In an embodiment, please continue to refer to fig. 2, if the electric quantity of the charging device does not reach the preset electric quantity threshold, the method further includes step S600.
Step S600: and updating the state of the equipment to be charged into the equipment to be charged in the first echelon.
Specifically, if the residual output power of the charging pile does not reach the required power of the charging equipment to be charged, and when the electric quantity of the charging equipment which does not exist reaches the preset electric quantity threshold value, the charging pile cannot supply power to the charging equipment to be charged. At this time, the device to be charged enters a queuing state, and the controller updates the state of the device to be charged into the device to be charged in the first echelon. Furthermore, when a plurality of devices to be charged exist and the charging device reaching the preset electric quantity threshold value stops charging, and the residual output power of the charging pile cannot meet the demand power of all the devices to be charged, the devices with the demand power smaller than the residual output power of the charging pile are preferentially powered. And if a plurality of devices to be charged with required power smaller than the residual output power of the charging pile exist, power is supplied according to the sequence of the queuing time of the devices, and the state of the devices to be charged which continue to queue is updated to the devices to be charged in the first echelon.
Furthermore, while updating the device state, the controller may update a queuing identifier of the device, for example, a first queue identifier corresponds to a device to be charged in a first fleet, and for a device to be charged in the same fleet, the queuing identifier corresponds to the sequence of queuing time. It can be understood that when there are multiple devices to be charged in the first fleet, the charging configuration may be performed according to the sequence of the queuing time. Further, the controller can also send the queuing identifier to the device to be charged, so that a user can acquire current queuing information in time and determine whether to continue queuing according to the queuing information.
In the above embodiment, if the remaining output power of the charging pile does not reach the required power of the device to be charged and the electric quantity of the charging device does not reach the preset electric quantity threshold value, the state of the device to be charged is updated to the device to be charged in the first echelon, so that the charging configuration can be performed subsequently according to the state information of the device to be charged, and the improvement of the scientificity of the charging control method is facilitated.
In one embodiment, after step S400, step S700 is further included.
Step S700: and updating the state of the charging equipment to be charged in the second echelon.
Specifically, when the fact that the electric quantity of the charging equipment reaches a preset electric quantity threshold value is detected, and the sum of the residual output power of the current charging pile and the charging power of the charging equipment reaches the required power of the equipment to be charged, the charging equipment enters a queuing state after power supply of the charging equipment is stopped. At this time, the controller updates the state of the second-team to-be-charged device, and the charging priority of the second-team to-be-charged device is lower than that of the first-team to-be-charged device.
Further, while updating the device state, the controller may update a queuing identifier of the device, for example, a second queuing identifier corresponding to a device to be charged in a second fleet, and for a device to be charged in the same fleet, the queuing identifier corresponds to the sequence of queuing time. It can be understood that when there are a plurality of devices to be charged in the second fleet, the charging configuration may be performed according to the sequence of the queuing time. Further, the controller can also send the queuing identifier to the device to be charged, so that a user can obtain current queuing information in time and determine whether to continue queuing according to the queuing information.
Further, when the electric quantity of the to-be-charged equipment newly connected to the charging potential is higher than a preset electric quantity threshold value and the residual output power of the current charging pile does not reach the required power of the to-be-charged equipment, the to-be-charged equipment enters a queuing state, and the controller updates the state of the to-be-charged equipment into the to-be-charged equipment in the second echelon.
In the above embodiment, when it is detected that the electric quantity of the charging device reaches the preset electric quantity threshold value, and the sum of the remaining output power of the current charging pile and the charging power of the charging device reaches the required power of the device to be charged, after the power supply to the charging device is stopped, the controller updates the state of the charging device to the state of the second echelon device to be charged, so that the subsequent charging configuration is performed according to the state information of the device to be charged, and the improvement of the scientificity of the charging control method is facilitated.
In one embodiment, after step S500, step S800 is further included.
Step S800: and changing the state of the equipment to be charged into the charging equipment.
Specifically, after the power is supplied to the device to be charged, the device to be charged finishes queuing and enters a charging state, and at the moment, the controller changes the state of the device into the charging device, so that the charging configuration can be conveniently performed according to the state information of the device to be charged, and the scientificity of the charging control method can be improved.
