Description

Technical Field

[0002] Electric bikes are popular among the public due to their convenience, low cost, and environmental friendliness, making them a primary means of transportation. However, as the number of electric bikes increases, the damage caused by their charging to low-voltage distribution networks is becoming increasingly serious.

[0003] Low-voltage distribution networks use three-phase power, while e-bikes charge using single-phase AC. Furthermore, e-bike charging behavior is somewhat random. Improper charging station planning, or users concentrating charging on one or two phases, can cause three-phase imbalance in the low-voltage distribution transformer. This is particularly true in densely populated residential areas, where e-bike charging is concentrated during peak hours and coincides with peak electricity demand. This further exacerbates the load pressure on distribution stations, increasing the peak-to-valley load difference and threatening the safe and stable operation of the distribution network.

[0004] Therefore, there is an urgent need for a method that can control the orderly charging of electric bicycles to stabilize the three-phase voltage balance in the low-voltage distribution station area. Summary of the Invention

[0034] Low-voltage distribution networks operate on a three-phase power supply. Overloading one or two phases of a distribution transformer can exacerbate the transformer's three-phase imbalance. Overloaded transformers heat up the transformer windings and transmission lines, consuming energy and causing voltage drops.

[0035] At the same time, electric bicycles currently on the market all use batteries to store electrical energy. Although the energy storage capacity of a single battery is small, the number of electric bicycles is huge, and they have a certain terminal load adjustment capability. If the charging of electric bicycles is controlled in an orderly manner, peak shaving and valley filling can be achieved without adding additional energy storage devices, thereby reducing the peak-to-valley difference in the power grid.

[0036] To achieve the above objectives, the embodiments of the present application provide an orderly charging control method for an electric bicycle. To make the objectives, technical solutions, and advantages of this application more clear and explicit, the present application is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only intended to explain this application and are not intended to limit this application.

[0037] For example, the embodiments of the present application can be applied to Figure 1The application scenario shown in the figure includes a low-voltage distribution transformer, a charging pile, and an electric bicycle. The low-voltage distribution transformer supplies power to the charging pile, and the charging pile supplies power to the electric bicycle.

[0038] In some embodiments, the low-voltage distribution transformer supplies power to various areas within the substation, such as industrial areas, commercial areas, or residential areas. This application takes residential areas as an example to explain the technical solution in detail.

[0039] In some embodiments, a low-voltage distribution transformer supplies power to a residential area, where the load includes charging piles and other resident loads. Each phase of the three-phase circuit in the low-voltage distribution transformer can correspond to multiple charging piles. By controlling the load of multiple charging piles in each phase, the three-phase voltage balance of the residential area load is stabilized.

[0040] In some embodiments, a charging pile is equipped with multiple charging ports for charging multiple electric bicycles individually, wherein the charging pile is provided with a maximum output power and a maximum allowed charging time for each charging port.

[0041] The above is an explanation of the application scenarios of the orderly charging control method for electric bicycles. The following is a detailed explanation of the orderly charging control method for electric bicycles of this application.

[0042] Figure 2 This is a flow chart of an orderly charging control method for an electric bicycle provided by an embodiment of the present application, referring to Figure 2 , the method can be implemented through steps 101 to 103, which are described in detail as follows:

[0043] In step 101, a target electric bicycle charging instruction is executed to obtain the initial power of the target electric bicycle.

[0044] In some embodiments, when the target electric bicycle needs to be charged, the user sends a charging instruction to the charging station, and the charging station receives and executes the charging instruction.

[0045] Optionally, the charging instruction includes at least the charging time of the target electric bicycle. In order to prevent the battery of the electric bicycle from being overcharged and causing safety hazards, the user can set the charging time on the charging pile.

[0046] For example, the charging instruction includes the charging time and charging end time of the target electric bicycle. The so-called charging end time is the time when the user uses the electric bicycle. As long as the electric bicycle is fully charged before the charging end time, it is sufficient.

[0047] Furthermore, users can also change the charging end time according to actual needs.

[0048] Exemplarily, the charging instruction may also include the target electric bicycle, charging duration, charging start time, and charging end time.

[0049] Furthermore, the charging pile can adopt the time-of-use electricity price principle. Users can set the charging start time and charging end time of the target electric bicycle on the charging pile according to the electricity price in different time periods and the time of using the electric bicycle.

[0050] In some embodiments, after receiving the charging instruction from the user, the charging pile can pre-charge the target electric vehicle to obtain the initial power of the target electric bicycle charger.

[0051] Exemplarily, pre-charging can be that the charging pile charges the target electric vehicle for a short time, and the power calculation device in the charging pile calculates the instantaneous electric energy that needs to be provided to the target electric bicycle.

[0052] Optionally, after the charging pile obtains the initial power of the target electric bicycle, the initial power can be stored in the charging pile.

[0053] In this step, the charging pile can obtain the charging time, charging start time, charging end time and initial power of the target electric bicycle by receiving and executing charging instructions, so as to provide data support for the subsequent orderly power supply of the target electric bicycle by the charging pile, so as to ensure user needs while ensuring the three-phase balance in the substation as much as possible.

[0054] In step 102, the charging priority of the target electric bicycle is calculated based on the charging time and the initial power.

[0055] In some embodiments, the charging priority of the target electric bicycle can be calculated based on the charging time and initial power of the target electric bicycle.

[0056] For example, the charging priority expression can be expressed as:

[0057] δ=(T N / T max )*β+(P N / P max )*γ

[0058] Where, δ represents the charging priority of the target electric bicycle, T N Indicates the charging time of the target electric bicycle, T max represents the maximum charging time allowed by the charging pile, β represents the preset charging time influencing factor, P N represents the initial power of the target electric bicycle, P max It represents the maximum initial power allowed by the charging pile, and γ represents the preset initial power impact factor.

[0059] It should be noted that β and γ can be adjusted and set according to actual conditions.

[0060] Optionally, the charging priority may also be adjusted according to the charging start time and / or charging end time set by the user.

[0061] In one scenario, the charging priority of the target electric bicycle is calculated to be high priority, and the charging pile can be charged during peak electricity consumption, but the charging end time is set to a period of time after the peak electricity consumption period, then the charging priority of the target electric bicycle can be adjusted to low priority.

[0062] In one scenario, the charging priority of the target electric bicycle is calculated to be low priority, and the charging pile should temporarily suspend charging it, but if the charging end time is set to 2 hours later, the low charging priority of the target electric bicycle can be adjusted to high priority.

[0063] In this step, the charging pile can calculate the charging priority of the target electric bicycle based on the charging time and initial power of the target electric bicycle. It can also appropriately adjust the charging priority of the target electric bicycle based on the charging start time and charging end time to meet user needs and the load conditions of the low-voltage distribution transformer.

[0064] In step 103, based on the charging priority and the preset voltage difference range, the target electric bicycle is controlled to be charged.

[0065] In one scenario, the charging time set by the user may be in at least one of a peak power consumption period, a low power consumption period, and a stable power consumption period.

[0066] For example, when the charging time is from 19:00 to 21:00, the target electric bicycle is in the peak power consumption period and the stable power consumption period; when the charging time is from 16:00 to 19:00, the target electric bicycle is in the low power consumption period and the peak power consumption period; when the charging time is from 20:00 to 23:00, it is in the peak power consumption period, the stable power consumption period and the low power consumption period at the same time.

[0067] It should be noted that the peak power consumption period, the valley power consumption period and the stable power consumption period are only for the convenience of expressing the power supply load of the low-voltage distribution transformer. It is not a limitation of the power supply load of the low-voltage distribution transformer, nor does it divide the power supply load of the low-voltage distribution transformer into peak power consumption period, valley power consumption period and stable power consumption period.

[0068] As we all know, when the grid load is heavy, there will be a certain degree of voltage drop, that is, the power supply voltage of the transformer is no longer the rated 220V, but will be slightly lower than 220V; when the grid load is light, there will be a certain degree of voltage rise, that is, the power supply voltage of the transformer is no longer the rated 220V, but will be slightly higher than 220V.

[0069] In some embodiments, to accurately match the power supply load of the low-voltage distribution transformer and ensure that the charging of the electric bicycle is more consistent with the ideal load of the substation transformer, the present application divides the time period of the target electric bicycle charging time into multiple preset voltage difference intervals. Each preset voltage difference interval is determined based on the power supply voltage of the low-voltage distribution transformer.

[0070] Exemplarily, the present application divides the preset voltage difference intervals into four, namely: a first preset voltage difference interval, a second preset voltage difference interval, a third preset voltage difference interval and a fourth preset voltage difference interval.

[0071] Furthermore, the above four intervals correspond to the four types of power loads: peak, flat, and valley. That is:

[0072] The first preset voltage difference interval corresponds to the peak time period of power consumption, during which the power supply voltage of the low-voltage distribution transformer is the lowest.

[0073] The second preset voltage difference interval corresponds to the peak time period of electricity consumption, when the supply voltage of the low-voltage distribution transformer is lower than the rated voltage of the grid, 220V.

[0074] The third preset voltage difference interval corresponds to a stable power supply period, when the power supply voltage of the low-voltage distribution transformer is around the grid rated voltage of 220V.

[0075] The fourth preset voltage difference interval corresponds to the off-peak period of electricity consumption, when the supply voltage of the low-voltage distribution transformer is higher than the rated voltage of the grid by 220V.

[0076] It should also be noted that the first preset voltage difference interval to the fourth preset voltage difference interval in the example of this application are not limitations on the preset voltage difference intervals, and the preset voltage difference intervals can be divided according to specific circumstances.

[0077] In some embodiments, the charger can be controlled to charge the target electric bicycle based on the charging priority of the target electric bicycle and the preset voltage difference range of the charging time. Exemplarily, it can be divided into step 1031 and step 1031 as shown below:

[0078] In step 1031, all electric bicycles are sorted according to their charging priorities and preset voltage difference intervals to obtain the charging sequence and priority charging time of the target electric bicycle.

[0079] In some embodiments, the charging pile can obtain the charging time and initial power of all electric bicycles connected to the charging pile according to steps 101 and 102, and calculate the charging priority of each electric bicycle.

[0080] Optionally, the charging pile can also reasonably adjust the charging priority of each electric bicycle according to the charging start time and charging end time.

[0081] In some embodiments, the charging of all electric bicycles is sorted according to their charging priorities.

[0082] In some embodiments, a priority charging time for each electric bicycle can be set based on the charging priority of all electric bicycles, wherein the priority charging time is the time allowed for the electric bicycle to charge.

[0083] In step 1032, the electric bicycle is charged according to the charging sequence and priority charging duration of the target electric vehicle.

[0084] In some embodiments, the target electric vehicle is charged according to the charging sequence and the priority charging time. When the priority charging time expires, the charging pile stops charging the target electric vehicle.

[0085] For example, when there are 9 high-priority electric bicycles that need to be charged, and the charging time is in the first preset voltage difference range, 4 of the electric bicycles will be charged for a limited time of 10 minutes first, and then the remaining 5 electric bicycles will be charged for a limited time of 10 minutes, and then the 4 electric bicycles that were charged first will be charged for a limited time of 10 minutes, and so on.

[0086] In some scenarios, as the charging pile charges the target electric bicycle, electric bicycles are connected to and left the charging pile one after another, and as time goes by, the preset voltage difference range within which the charging time of each electric bicycle falls also changes.

[0087] In some embodiments, the charging station has a preset update time built in. That is, after a period of time, the charging station will recalculate the charging priority of each electric bicycle based on the charging instructions and initial power of all electric bicycles connected to the charging station, and reasonably adjust the charging priority of each bicycle.

[0088] Optionally, the priority charging time of the target electric bicycle may also be the charging time allowed for the electric bicycle within a preset update time.

[0089] It should be pointed out that the preset update time can be adaptively adjusted according to the number of connected electric bicycles and the load of the low-voltage distribution network transformer.

[0090] In this step, with the dual goals of stabilizing the power supply load of the low-voltage distribution transformer and user demand, the electric bicycles can be charged in an orderly manner by controlling the charging sequence and charging time of the electric bicycles.

[0091] In some embodiments, before the charging pile executes the target electric bicycle charging instruction, the electric bicycle orderly charging control method provided in the present application further includes: determining a daily voltage characteristic curve.

[0092] Figure 3 This is a flow chart of determining a daily voltage characteristic curve provided by an embodiment of the present application, referring to Figure 3 , the method can be implemented through steps 104 to 106, as detailed below:

[0093] In step 104 , a preset number of instantaneous voltages in a preset sampling period are collected.

[0094] In some embodiments, the charging pile can collect instantaneous voltages for multiple sampling periods using a built-in voltage collection device, wherein a preset number of collection points are set in each sampling period.

[0095] For example, the 10 days of continuous data collection are divided into 20 sampling periods, i.e., one sampling period is one day, and each sampling period is set with 96 collection points, i.e., the instantaneous voltage of the charging pile is collected every 15 minutes. The instantaneous voltage is the voltage supplied by the transformer to the charging pile.

[0096] In step 105 , a voltage characteristic curve of each preset sampling period is determined according to a preset number of instantaneous voltages in each preset sampling period.

[0097] For example, the voltage characteristic curve of each sampling period is determined based on the 96 instantaneous voltages collected in each sampling period. 20 voltage characteristic curves can be drawn from 20 sampling periods.

[0098] In step 106 , the voltage characteristic curves of a plurality of preset sampling periods are fitted using the least square method to determine a daily voltage characteristic curve.

[0099] For example, a least squares method is used to fit 20 voltage characteristic curves to determine a reasonable daily voltage characteristic curve. The daily characteristic curve is the supply voltage at different times when the transformer supplies power to the charging pile.

[0100] In some embodiments, the above-mentioned electric bicycle orderly charging control method can also be combined with the daily voltage characteristic curve to more accurately determine the preset voltage difference range.

[0101] Exemplarily, the preset voltage difference interval is determined by the following steps, including:

[0102] According to the daily voltage characteristic curve and the rated voltage of the grid, the voltage difference between the two is obtained.

[0103] The daily voltage characteristic curve is divided into a plurality of preset voltage difference intervals according to a plurality of preset voltage difference thresholds and voltage differences.

[0104] The technical solution provided in the embodiment of the present application controls the charging and power-off of a single electric bicycle in an orderly manner based on the charging priority of the electric bicycle and the three-phase voltage balance of the low-voltage substation, avoids the centralized charging of all electric bicycles, prevents the overload of the distribution transformer, realizes the peak-to-valley difference within the distribution substation, and reduces the three-phase imbalance of the distribution transformer.

[0105] In order to verify the feasibility and beneficial effects of the technical solution of this application, a specific description is given by taking an AC charging station for electric bicycles in a residential building as an example.

[0106] The residential building's electric bicycle AC charging station is equipped with three 10-way electric bicycle charging piles, each with a rated input voltage of 220V, a maximum output power of 2.2kW per pile, and a maximum charging time of 10 hours per pile. The charging piles are numbered 381-1, 381-2, and 381-3, with 381-1 installed on phase A of the low-voltage distribution network transformer, 381-2 on phase B of the low-voltage distribution network transformer, and 381-3 on phase C of the low-voltage distribution network transformer.

[0107] The sampling period of the charging pile is 900 seconds, and the number of collections in each sampling period is 900 times, that is, the instantaneous value of the power supply line voltage is sampled once per second. The charging pile collects the instantaneous voltage value for 7 consecutive days, and the 96-point data stored daily is fitted using the least squares method to obtain the voltage characteristic curve. The daily voltage characteristic curves in the last 7 days are then superimposed and averaged to obtain the daily characteristic voltage curve.

[0108] The voltage difference α of the daily voltage characteristic curve relative to the rated voltage of the grid is calculated. According to the different value ranges of α, the characteristic voltage curve is divided into four intervals: sharp, peak, flat, and valley. See Table 1 for details.

[0109] Table 1 Peak, flat, valley intervals and control strategies

[0110] interval α value range Voltage range Control strategy tip ≥+8 ≥230V Start charging peak +5～+10 225V~230V Start charging flat -5～+5 215V~225V Stop charging valley ＜-5 ＜215V Stop charging

[0111] For the sake of convenience, assume that 3 charging piles are connected to 30 users, the current time is 18:00, and the charging time of the electric bicycle is T N , the initial power P of the electric bicycle N , the charging time influence factor β is set to 0.3, and the initial power influence factor γ is set to 0.7. According to the calculation expression of charging priority δ δ=(T N / Tmax )*β+(P N / P max )*γ, calculate the charging priority of all electric bicycles, as shown in Table 2 below:

[0112] Table 2 Charging priority of electric bicycles

[0113]

[0114]

[0115] The charging piles charge or disconnect the 30 electric motorcycles based on their priority. With a 5-minute update interval, the charging piles start charging in order of user priority weights δ, from high to low, during peak periods and stop charging in order during valley periods.
