Description

Technical Field

[0001] The present application relates to the field of electronic information, and in particular to a charging control method and apparatus, equipment, and computer-readable storage medium. Background Art

[0002] With the development of new energy and the increasing demand for environmental protection, electric vehicles are becoming more and more popular, and therefore, the demand for charging electric vehicles is increasing.

[0003] Currently, the number of charging stations is far from sufficient. Even if a station is equipped with multiple charging guns, vehicles that connect later often need to wait until the earlier vehicles are fully charged before they can charge. This results in excessive waiting times for vehicles. Alternatively, charging stations can charge multiple electric vehicles simultaneously, but due to power costs, the amount of power input to each electric vehicle is often very small, resulting in excessive charging times.

[0004] At the same time, since the charging time of electric vehicles is often long, users usually choose to fully recharge their electric vehicles during fixed idle time periods, such as at night. However, due to various reasons, electric vehicles may need to replenish a small amount of power rather than all of the power during non-recharging periods. In this case, users often need to obtain a certain amount of power as soon as possible so that the electric vehicle can have a certain endurance (for example, from the supermarket to home).

[0005] In summary, how to restore the terminal to service as quickly as possible without significantly increasing the investment cost of charging equipment has become an urgent problem to be solved. Summary of the Invention

[0088] The charging control method disclosed in the embodiment of the present application can be applied to the following scenarios: the power terminal cannot be used due to insufficient power, and is charged using a charging device. The purpose is to restore the power terminal to use as soon as possible without increasing the investment cost of the charging device.

[0089] It is understandable that the power-consuming terminal can be an electric vehicle, a communication terminal (such as a mobile phone) and other power-driven equipment, or it can be a movable charging unit, such as a shared power bank.

[0090] It should be noted that although the purpose of the embodiments of the present application is to restore the use of a power-consuming terminal that has been unavailable due to insufficient power as soon as possible, the technical solutions described in the embodiments of the present application are not limited to controlling the charging of power-consuming terminals that have been unavailable due to insufficient power, but are applicable to controlling the charging of all power-consuming terminals connected to a charging device. After a power-consuming terminal is connected to a charging device, it obtains electrical energy from the charging device. Therefore, in the following embodiments, a power-consuming terminal is also referred to as a charged terminal.

[0091] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0092] Figure 1 This is an example of an application scenario of a charging control method disclosed in the embodiment of this application. In this embodiment, the charged terminal is an electric vehicle and the charging device is a charging pile supporting the electric vehicle. Specifically, Figure 1 In the system, one charging pile is connected to six charging guns, each of which can be connected to an electric vehicle. After the charging gun is connected to the electric vehicle, it can charge the electric vehicle.

[0093] Figure 2 A charging control method disclosed in an embodiment of the present application is provided by a charging device, such as Figure 1 The charging pile in the implementation, Figure 2 The following steps are included:

[0094] S201: Detect the target terminal.

[0095] The target terminal is a charged terminal that meets a preset condition. In this embodiment, the preset condition is connected. That is, as long as the electric vehicle is connected to the charging pile through the charging gun, it is the target terminal.

[0096] Specifically, the implementation method of detecting the target terminal may refer to the prior art. For example, optionally, the target terminal is periodically detected with a preset time period as a period.

[0097] S202: charging the target terminal in turn.

[0098] In this embodiment, the meaning of taking turns is that at the same time, only one target terminal is charged, and after the taking turns criterion is met, the next target terminal is charged.

[0099] The order of the target terminals used as a rotation basis can be random or set according to configuration rules. Optionally, the order of the target terminals can be determined according to the order in which the charging guns are connected. For example, assuming Figure 1 In the example, the six electric vehicles are connected in sequence from left to right, so the order of rotation is from left to right. From the above meaning of rotation, it can be seen that when the charging pile is connected to multiple electric vehicles, there is only one output at any time. For example, Figure 1 In the middle, the first electric car from the left is charging while the others are waiting.

[0100] The rotation is based on the charging duration or the power consumed by the target terminal. Specifically, the rotation from the first target terminal (i.e., any target terminal) to the second target terminal in the rotation order is based on: the charging duration of the first target terminal reaches a preset duration threshold, or the power consumed by the first target terminal reaches a preset power threshold.

[0101] Optionally, in order to maximize the satisfaction of the need to restore the normal use of electric vehicles as soon as possible, the interval between two times of charging of any target terminal should be controlled within a range. Because the rotation is based on the rotation basis, specifically, the time threshold and power threshold in the rotation basis ensure that the interval between two adjacent charging start times of any target terminal is no greater than the preset interval threshold.

[0102] Furthermore, taking electric vehicles as an example, since it takes several hours or even more than ten hours to fully charge an electric vehicle's battery, the preset interval threshold can be one hour. This significantly reduces the waiting time for electric vehicles in the order of priority, compared to waiting for electric vehicles in the previous order to be fully charged. If the preset interval threshold is one hour, the rotation interval is 12 minutes.

[0103] Optionally, in order to maximize the need to restore the electric vehicle to normal use as soon as possible, in S202, the maximum output power can be used to charge the target terminal in turn. That is, when charging any connected electric vehicle, the maximum output power of the charging pile is used for charging. Among them, the maximum output power scenario can include two types: 1. The charging pile can obtain the first power, and the maximum output power is the obtained power, that is, the first power. 2. The charging pile can obtain the first power, but only a part of the first power, that is, the second power, is used for charging, and the other part of the power is used for other purposes. In this case, the maximum power that can be used for charging, that is, the second power, is used to charge the target terminal in turn.

[0104] Figure 2 In the process shown, the target terminals are charged in turns, and the charging duration or the amount of power the target terminals have received is used as the basis for the rotation. Therefore, by pre-configuring the thresholds for charging duration or the amount of power the target terminals have received, the goal of quickly and evenly distributing the power to each target terminal can be achieved.

[0105] Therefore, compared with the existing technology, Figure 2 The technical solution shown can distribute the limited power equally to each charged terminal as quickly as possible, so that the charged terminals can be used as soon as possible. Therefore, even if the total power is not increased or the charging equipment structure is not upgraded to control costs, the terminals connected to the charging piles can be used normally as quickly as possible.

[0106] For example, the charging period for electric vehicles is 0:00-7:00, which means charging takes place during the night. However, the driving distance or time during the day may be too long, so recharging is required during the day. However, in the prior art, even if an electric vehicle is connected to a charging pile, for a charging pile with multiple charging guns, the total output power of the charging pile is limited. Therefore, even if recharging can start immediately, the waiting time is long, or it is necessary to wait for the first connected car to be fully charged before recharging can begin, which also takes a long time. In the charging control method described in this embodiment, the charging piles charge the connected electric vehicles in turn, dividing the limited power equally among the electric vehicles as quickly as possible. Therefore, any electric vehicle can obtain enough power for normal use as soon as possible (for example, just driving home from the supermarket).

[0107] In order to improve the user experience, the charging device can optionally be connected to an electronic device such as a mobile phone, so that a client running on the electronic device can display the charging status, etc.

[0108] Figure 3 This is another charging control method disclosed in an embodiment of the present application. Compared with the above embodiments, it adds the functions of the electronic device and the conditions for determining the target terminal.

[0109] Figure 3 The following steps are included:

[0110] S301: The charging device detects the target terminal.

[0111] In this embodiment, in addition to being connected to the charging device, the charged terminal must also meet at least one of the following conditions to be identified as a target terminal:

[0112] 1. The remaining battery power is less than the first preset value. 2. The cruising range is less than the second preset value.

[0113] The first and second values ​​can be pre-configured manually. Using the remaining battery level and / or range as criteria for determining the target terminal allows for prioritizing charging for devices with low battery levels and / or low range. This prioritizes the weakest terminals, allowing them to be used as quickly as possible, thereby increasing charging station availability.

[0114] S302: The charging device sends the basis for switching from the first target terminal to the second target terminal to the client.

[0115] S303: The client displays the above-mentioned evidence.

[0116] The purpose of S302-S303 is to enable the user to know the basis of charging rotation, so as to improve the user's usage experience.

[0117] Optionally, the client can also connect to the electric vehicle and send the electric vehicle's range to the charging device. Alternatively, the charging device uses other methods to obtain the electric vehicle's range.

[0118] S304: The charging devices charge the target terminals in turn.

[0119] It should be noted that the execution order of S302 - S304 is not limited.

[0120] Figure 3 The process shown further limits the conditions of the target terminal, so that terminals with insufficient power and / or insufficient battery life are given priority in rotation charging, and the interaction with the client can improve the user experience of the charging device.

[0121] It should be noted that the range parameter is an example of a range parameter for electric vehicles, which indicates the endurance of the terminal. For other charged terminals, other appropriate range parameters, such as endurance duration, can be used, and the second parameter needs to be adjusted accordingly.

[0122] Figure 2 as well as Figure 3In the paper, the process of rotating charging is disclosed. On this basis, combined with the existing "group charging" technology, rotating charging based on "group charging" can be realized. In this case, Figure 1 The charging pile shown in the figure can be replaced by a charging device with a "group charging" function. In practice, the charging device with the "group charging" function may include a charging terminal (which may include a charging gun, display, interactive equipment, etc.) and a charger (also called a box transformer or a master control box), wherein the charger is used to provide electrical energy. Based on this structure, the charger can be used as the executor of the following method embodiments. However, the following embodiments do not limit the structure of the charging device with the "group charging" function. For the implementation strategy and circuit of the "group charging" function, please refer to the prior art. In the following embodiments, charging in turns is implemented on the basis of the "group charging" function.

[0123] Figure 4 Another charging control method disclosed in an embodiment of the present application is applied to a charging device and includes the following steps:

[0124] S401: Using a first power, charging a charged terminal that meets a first preset condition simultaneously.

[0125] The first preset condition at least includes being connected. The first preset condition may also include other limiting contents, which can be found in the prior art and will not be described in detail here.

[0126] S402: Using the second power, charging the target terminal in turn.

[0127] The target terminal is a charged terminal that meets a second preset condition. The second preset condition at least includes being connected. Optionally, as described above, the second preset condition may further include at least one of: a remaining battery level less than a preset first value, and a battery life parameter less than a preset second value.

[0128] In this embodiment, the meaning of taking turns, the basis for taking turns, the output power, etc. can all be found in the above embodiments and will not be repeated here.

[0129] Because the solution described in this embodiment uses rotating charging based on "group charging," which typically uses lower power to reduce costs, in this embodiment, the second power can optionally be greater than the first power. This is intended to improve the ease of implementing rotating charging based on existing "group charging." For example, the first power for each terminal is 2kW, and the second power is 15kW.

[0130] Specifically, while using the first power to charge the charged terminals that meet the first preset condition, the second power can be used to charge the target terminals in turn.

[0131] The following will target Figure 4 The different contents of the second preset condition in the illustrated process are respectively used as examples to illustrate the rotating charging based on “group charging”.

[0132] 1. Average charge

[0133] The charging station has two branches: the first branch is for group charging, and the second branch is for rotating charging. The second branch has a maximum output power of 15 kW. The first branch uses 2 kW each to charge six electric vehicles in a group. The second branch uses 15 kW to charge the six electric vehicles in a rotating manner while simultaneously performing group charging. This means that the second pre-condition is connected.

[0134] Table 1 shows an example of average charge parameters.

[0135] Table 1

[0136]

[0137]

[0138] In Table 1, 15 indicates that the charging time for any electric vehicle is 15 minutes each time. 6 indicates the number of vehicles participating in the charging rotation.

[0139] 2. Smart charging

[0140] The second preset condition includes being connected, the remaining power being less than a preset first value, and the endurance parameter being less than a preset second value. Assume that the electric vehicles connected to guns 1, 3, and 5 meet the second preset condition.

[0141] The first branch uses 2 kW each to charge six electric vehicles in a group. The second branch alternately charges the electric vehicles connected to guns 1, 3, and 5. The output power for each electric vehicle is 15 kW.

[0142] Examples of smart charging parameters are shown in Table 2:

[0143] Table 2

[0144]

[0145] In Table 2, SOC represents the percentage of remaining power.

[0146] Figure 4 The illustrated process implements rotating charging, building upon group charging. Because group charging typically takes longer, rotating charging can complement group charging, allowing the target device to resume normal use as quickly as possible. Furthermore, the example uses both average charging and smart charging, allowing for the configuration of the second preset condition based on actual needs, thus diversifying application examples.

[0147] Furthermore, the client can be used to perform more precise control over the rotating charging based on "group charging". Figure 5 Another charging control method disclosed in an embodiment of the present application includes the following steps:

[0148] S501: The charging device uses a first power to charge a charged terminal that meets a first preset condition.

[0149] S502: The charging device receives a reservation message sent by the client.

[0150] The reservation message includes the identifier of the reservation terminal. The setting method of the identifier can refer to the existing technology.

[0151] S503: The charging device confirms that the connected charged terminal with the above identification is a reserved charged terminal.

[0152] Optionally, in addition to the identification as a basis, other reservation conditions may also be specified, such as the remaining power being less than a preset first value, and / or the endurance parameter being less than a preset second value.

[0153] S504: The charging device uses the second power to charge the reserved terminal within the reserved time period.

[0154] The appointment time period can be pre-configured. For example, the appointment time period is within one hour of receiving the appointment message. Another example is the pre-specified time range: 9:00 am to 11:00 am every day.

[0155] Optionally, the reserved time periods of different charged terminals do not overlap, so that the second power can be used in a concentrated manner to charge one charged terminal.

[0156] Optionally, in order to ensure that each charged terminal resumes normal use as soon as possible, that is, to mainly ensure the implementation of charging in rotation, the number of terminals that reserve charging can be limited. For example, there are only two places for charging reservations in one day, and the one who reserves first can get the place first. The specific implementation method can be found in the existing technology and will not be repeated here.

[0157] S505: The charging device determines that a charged terminal that meets a second preset condition is a target terminal.

[0158] The second preset condition is that the terminal is not scheduled to be charged and is already connected to the charging device. This means that the terminals that have been charged within the scheduled time period will no longer participate in the charging rotation, so that other terminals can resume normal use as soon as possible.

[0159] It is understandable that the second preset condition may further include: the remaining power is less than a preset first value, and / or the endurance parameter is less than a preset second value.

[0160] S506: The charging device uses the second power to charge the target terminal in turn.

[0161] Optionally, the first power is the power output by the first charging branch, and the second power is the maximum output power of the second charging branch.

[0162] S507: The charging device sends the basis for switching from the first target terminal to the second target terminal to the client.

[0163] S508: The client displays the above charging basis.

[0164] The following is for Figure 5 The different contents of the second preset condition in the illustrated process are respectively used as examples to illustrate the rotating charging based on “group charging”.

[0165] 1. Make an appointment to recharge

[0166] The charging station has two branches: the first branch is for group charging, and the second branch is for rotating charging. The second branch has a maximum output power of 15 kW. The first branch uses 2 kW each to charge six electric vehicles in a group.

[0167] Assume that all six charging guns are connected to electric vehicles. From the left, the users of the last two electric vehicles use the client to send reservation messages in advance.

[0168] After receiving the reservation message, the charging pile uses the second branch to make a reservation for charging for the vehicle that sent the reservation message first between 9:00 and 10:00, with an output power of 15kw. It also uses the second branch to make a reservation for charging for the vehicle that sent the reservation message later between 10:00 and 11:00, with an output power of 15kw.

[0169] After completing the scheduled charging, the charging pile uses the second branch to charge the first four electric vehicles in turn, and the output power of each electric vehicle charged in turn is 15kw.

[0170] Examples of various parameters for scheduled charging are shown in Table 3.

[0171] Table 3

[0172]

[0173] 2. Smart appointment charging

[0174] like Figure 1As shown, the charging station has two branches: the first branch is used for group charging, and the second branch is used for rotating charging. The maximum output power of the second branch is 15 kW. The first branch uses 2 kW each to charge six electric vehicles in a group.

[0175] Assume that all six charging guns are connected to electric vehicles. From the left, the users of the last two electric vehicles use the client to send reservation messages in advance.

[0176] After receiving the reservation message, the charging pile uses the second branch to make a reservation for charging for the vehicle that sent the reservation message first between 9:00 and 10:00, with an output power of 15kw. It also uses the second branch to make a reservation for charging for the vehicle that sent the reservation message later between 10:00 and 11:00, with an output power of 15kw.

[0177] After the scheduled charging is complete, the charging pile determines which electric vehicle to charge in turn from the first four electric vehicles. Assuming that only the remaining power of the first and third electric vehicles is less than the first value, and the remaining power of the other electric vehicles is greater than the first value, the second electric vehicle only needs to be "group charged" and no further rotation charging is required. The charging pile uses the second branch to charge the first and third electric vehicles in turn, with the output power of each electric vehicle being 15kW.

[0182] visible, Figure 5 The technical solution shown can be combined with the "group charging" technology to perform rotational charging on the basis of "group charging". Because the output power of "group charging" is limited, the charging time is often longer. Therefore, combined with rotational charging, it can help the charged terminal obtain the required electrical energy as soon as possible. And, further, because it has the basis of "group charging", even if the charged terminal is not selected as the object of rotational charging, it can still obtain electrical energy, and by setting the second preset condition, it can be ensured that the charged terminal that does not participate in the rotational charging can be used normally. Therefore, it is in line with the idea of ​​enabling the charged terminal to be used normally as soon as possible in the embodiment of the present application.
