Description

Technical Field

[0001] The present invention relates to the technical field of charging power distribution, and particularly to a personalized charging power distribution method, system, medium and processor. Background Art

[0002] As the market share of electric vehicles is increasing, in order to meet the charging needs of various types of electric vehicles, charging stations have established a certain number of charging piles with different available output powers to charge electric vehicles with different powers.

[0003] Chinese Patent Application No. CN202410480228.9 discloses a dynamic power distribution method, device and electronic device for a DC charging pile. Based on the reservation information of the vehicle to be charged, the charging priority of the vehicle to be charged is determined; when the required power is greater than the preset power of the charging pile, the actual charging powers of multiple charging piles in the charging station are adjusted according to the charging priority of the vehicle to be charged, so that the actual charging powers of multiple charging piles are all reduced by a first standard power, and the actual power of the charging pile corresponding to the vehicle to be charged is increased by the sum of the first standard powers reduced by multiple charging piles.

[0004] Another example is Chinese Invention No. CN202410220252.9, which discloses a charging power distribution method and electronic device. In this method, the charging demand information of each charging pile in the target charging group is obtained, the actual group distribution power of the target charging group is determined, the upper limit power of each charging pile in the target charging group is determined, and the actual distribution power of each charging pile is determined according to the actual group distribution power, the charging demand information of the pile and the upper limit power of the pile.

[0005] The above solutions either determine the power distribution priority through reservation or determine the power distribution scheme through the rigid conditions of the charging pile and the electric vehicle. Not only is the scheme calculation complex, but also after the charging state of some charging piles changes, the charging powers of other charging piles cannot be dynamically linked and adjusted, and the flexibility and personalization of the distribution are poor.

[0006] In view of this, a personalized charging power distribution method, system, medium and processor are needed. Summary of the Invention

[0007] Aiming at the problems in the prior art that the power distribution scheme is complex, the charging powers of other charging piles cannot be dynamically linked and adjusted, and the flexibility and personalization of the distribution are poor, the present invention provides a personalized charging power distribution method, system, medium and processor, which can simplify the power distribution calculation scheme, and at the same time can dynamically link and adjust the charging powers of other charging piles, improving the personalized requirements and flexibility. The specific technical solutions are as follows:

[0008] A personalized charging power distribution method includes the following specific steps:

[0009] S1: Obtain the total charging power of the charging station and the total number of charging piles, and calculate the reference power based on this;

[0010] S2: Obtain the maximum charging power of the charging piles in use and the maximum charging power of the electric vehicles being charged, and use the smaller of them as the current upper limit power of the charging pile;

[0011] S3: Obtain the number of idle charging piles, and calculate the superposition power in combination with the reference power;

[0012] S4: Obtain the power transfer information of the charging piles and calculate the transfer power of each charging pile;

[0013] S5: Calculate the sum of the reference power, superposition power and transfer power of each charging pile in use, and compare it with the upper limit power of the charging pile. If the upper limit power is smaller, use the upper limit power as the charging power of the charging pile. Otherwise, use the sum of the reference power, superposition power and transfer power of the charging pile as the charging power of the charging pile, and return to step S3.

[0014] Further, when calculating the reference power, the average value obtained by dividing the total charging power by the total number of charging piles is used as the reference power.

[0015] Further, the step of obtaining the number of idle charging piles and calculating the superposition power in combination with the reference power includes the following specific steps:

[0016] Obtain the number of idle charging piles in this charging station;

[0017] Multiply the reference power by the number of idle charging piles to obtain the idle power;

[0018] Obtain the number of charging piles in use in this charging station, and evenly distribute the idle power to the charging piles in use to obtain the superposition power.

[0021] Obtain the power transfer request information sent by each charging pile for receiving. The power transfer request information contains the value of the requested received power, and calculate the total value of the requested received power;

[0022] Compare the total value of the transferred-out power and the total value of the transferred-in power; if the total value of the transferred-out power is equal to the total value of the transferred-in power, each transferred-out and transferred-in charging pile uses the value requested by itself as its own transferred power; if the total value of the transferred-out power is greater than the total value of the transferred-in power, each transferred-in charging pile uses the value requested by itself as its own transferred power, and each transferred-out charging pile uses the value requested by itself multiplied by the transfer ratio as its own transferred power; if the total value of the transferred-out power is less than the total value of the transferred-in power, each transferred-out charging pile uses the value requested by itself as its own transferred power, and each transferred-in charging pile uses the value requested by itself multiplied by the transfer ratio as its own transferred power.

[0023] Further, the transfer ratio is the ratio of the total value of the transferred-in power to the total value of the transferred-out power; the transfer ratio is the ratio of the total value of the transferred-out power to the total value of the transferred-in power.

[0024] Further, it further includes the following steps: set the transferred power of the charging piles that cannot participate in the transfer to 0; the transferred power of the transferred-in charging piles is a positive value; the transferred power of the transferred-out charging piles is a negative value.

[0025] Further, in step S4, it further includes the following steps:

[0026] Before comparing the total value of the transferred-out power and the total value of the transferred-in power, make the following judgments:

[0027] If the power value requested to be transferred out by a certain transferred-out charging pile is greater than the sum of the reference power of the charging pile and the superimposed power, then use the sum of the reference power of the charging pile and the superimposed power as the power value requested to be transferred out by the charging pile;

[0028] If the upper limit power of a certain transferred-in charging pile is less than the sum of the reference power of the charging pile and the superimposed power, the charging pile power transfer request information is regarded as invalid.

If the upper limit power is smaller, the upper limit power is used as the charging power of the charging pile; otherwise, the sum of the reference power, superimposed power and transfer power of the charging pile is used as the charging power of the charging pile, and return to step S3.

[0045] Embodiment 1

[0046] like Figure 1 A flowchart of a personalized charging power allocation method includes the following specific steps:

[0047] S1: Obtain the total charging power of the charging station and the total number of charging piles, and calculate the benchmark power based on them;

[0048] S2: Obtain the maximum charging power of the charging pile in use and the maximum charging power of the corresponding electric vehicle being charged, and use the smaller one as the current upper limit power of the charging pile;

[0049] S3: Obtain the number of idle charging piles and calculate the superimposed power in combination with the benchmark power;

[0050] S4: Obtain power transfer information of the charging piles and calculate the transfer power of each charging pile;

[0051] S5: Calculate the sum of the baseline power, superimposed power and transfer power of each charging pile in use, and compare it with the upper limit power of the charging pile. If the upper limit power is smaller, the upper limit power is used as the charging power of the charging pile. Otherwise, the sum of the baseline power, superimposed power and transfer power of the charging pile is used as the charging power of the charging pile, and return to step S3.

[0052] The power allocation scheme of the present application can simplify the power allocation calculation, and can dynamically adjust the charging power of other charging piles, thereby improving personalized needs and flexibility.

[0053] In a specific implementation, the calculation reference power is to divide the total charging power by the total number of charging piles to obtain an average value as the reference power, and the calculation formula is as follows:

[0054] P j =P z / N z ;

[0055] Upper middle, P j is the reference power, P z is the total charging power of the charging station; Nz The total number of charging piles in the charging station.

[0056] In specific implementation, obtaining the number of idle charging piles and calculating the superimposed power in combination with the reference power includes the following specific steps:

[0057] Obtain the number of idle charging piles in this charging station;

[0058] Multiply the reference power by the number of idle charging piles to obtain the idle power;

[0059] Obtain the number of charging piles in use in this charging station, and evenly distribute the idle power to the charging piles in use to obtain the superimposed power. On the basis of the reference power, if some charging piles are in an unused state, the power share of the idle charging piles is evenly distributed to the charging piles in use as the superimposed power. First, it can make full use of the circuit equipment of the charging station. Second, it can improve the charging efficiency and save the charging time. The specific calculation formula is as follows:

[0060] P x =P j X N x ;

[0061] P dj =P x / N y ;

[0062] Among them, P x is the idle power, N x is the number of idle charging piles; P dj is the superimposed power; N y is the number of charging piles in use.

[0063] In specific implementation, obtaining the power transfer information of the charging piles and calculating the transfer power of each charging pile includes the following steps:

[0064] Obtain the power transfer request information sent by each charging pile for transfer. The power transfer request information includes the value of the requested transferred power, and calculate the total value of the requested transferred power;

[0065] Obtain the power transfer request information sent by each charging pile for reception. The power transfer request information includes the value of the requested received power, and calculate the total value of the requested received power;

[0066] Compare the total value of the transferred-out power and the total value of the transferred-in power; if the total value of the transferred-out power is equal to the total value of the transferred-in power, each transferred-out and transferred-in charging pile takes the value requested by itself as its transferred power; if the total value of the transferred-out power is greater than the total value of the transferred-in power, each transferred-in charging pile takes the value requested by itself as its transferred power, and each transferred-out charging pile takes the value requested by itself multiplied by the transfer ratio as its transferred power; if the total value of the transferred-out power is less than the total value of the transferred-in power, each transferred-out charging pile takes the value requested by itself as its transferred power, and each transferred-in charging pile takes the value requested by itself multiplied by the transfer ratio as its transferred power.

[0067] In specific implementation, the transfer ratio is the ratio of the total value of the transferred-in power to the total value of the transferred-out power; the transfer ratio is the ratio of the total value of the transferred-out power to the total value of the transferred-in power.

[0068] In specific implementation, the following steps are further included: set the transferred power of the charging piles that cannot participate in the transfer to 0; the transferred power of the transferred-in charging piles is positive; the transferred power of the transferred-out charging piles is negative.

[0069] In specific implementation, in step S4, the following steps are further included: before comparing the total value of the transferred-out power and the total value of the transferred-in power, make the following judgments:

[0070] If the power value requested to be transferred out by a certain transferred-out charging pile is greater than the sum of the charging pile reference power and the superimposed power, then take the sum of the charging pile reference power and the superimposed power as the power value requested to be transferred out by the charging pile;

[0071] If the upper limit power of a certain transferred-in charging pile is less than the sum of the charging pile reference power and the superimposed power, the charging pile power transfer request information is regarded as invalid.

[0072] Furthermore, the calculation formula for the transferred power is as follows:

[0073] If P c = P r : P zr = P qr ; P zc = P qc .

[0074] If P c > P r : P zr = P qr ; P zc = P qc × L c ; L c = P r / P c .

[0075] If P c < Pr : P zr = P qr × L r ; P zc = P qc ; L r = P c / P r .

[0076] In the above formula, P c is the total value of the requested power to be transferred out; P r is the total value of the requested power to be transferred in; P zr is the value of the transferred-in power; P qr is the value of the requested transferred-in power; P zc is the value of the transferred-out power; P qc is the value of the requested transferred-out power; L c is the transfer-out ratio; L r is the transfer-in ratio.

[0077] In specific implementation, calculate the sum of the reference power, superposition power, and transfer power of each charging pile in use, and compare it with the upper limit power of the charging pile. If the upper limit power is smaller, then use the upper limit power as the charging power of the charging pile; otherwise, use the sum of the reference power, superposition power, and transfer power of the charging pile as the charging power of the charging pile. The specific calculation formula is as follows:

[0078] For the charging pile with the transfer power being the transferred-in power:

[0079] If P sx < P j + P dj + P zr ; then P dc = P sx ;

[0080] If P sx > P j + P dj + P zr ; then P dc = P j + P dj + P zr .

[0081] For the charging pile with the transfer power being the transferred-out power:

[0082] If P sx < P j + P dj - P zc ; then P dc = P sx ;

[0083] If P sx > Pj +P dj -P zc ; then P dc =P j +P dj -P zc .

[0084] For charging piles without transfer power:

[0085] If P sx <P j +P dj ; then P dc =P sx ;

[0086] If P sx >P j +P dj ; then P dc =P j +P dj .

[0087] In the above formula, P sx is the upper limit power; P dc is the charging power that the charging pile actually charges the electric vehicle.

[0088] In specific implementation, by combining the upper limit power, reference power, and superposition power, the transfer power values that the vehicle owner can apply to transfer in and the transfer power values that can be applied to transfer out are prompted in real time, enabling the vehicle owner to select within this range to avoid exceeding the range.

[0089] By circularly detecting idle charging piles and transfer power request information, the power released by charging piles in various original usage states (including no transfer power, transfer-in power, and transfer-out power) can be redistributed and used. It is possible to perform rebalancing calculations after new charging piles are used, or to perform rebalancing calculations when the number of charging piles in use remains unchanged but the transfer power application changes, or when both the number of charging piles in use and the transfer power change occur simultaneously. By using the method of circularly calculating the superposition power and transfer power, after various usage states of the charging piles change, dynamic linkage balance calculations can be performed to meet the needs of all parties.

[0090] This application adopts a method of hierarchically dividing the charging power. First, the average value obtained by dividing the total charging power by the total number of charging piles is used as the reference power, which is used as the reference layer to ensure the basic charging needs of each charging pile. Generally, only when each charging pile has a charging demand and each charging pile has no intention of transferring the charging power, that is, when the superposition power and the transfer power are both zero, the charging power of each charging pile adopts the reference power. This is a basic guarantee and also reflects a basic fairness to users. Of course, in this case, the reference power is also less than the maximum charging power of the charging pile to ensure the basic use efficiency of the charging pile. If the reference power is greater than the maximum charging power of the electric vehicle, according to the scheme, the maximum charging power of the electric vehicle is used as the charging power. At this time, the difference between the reference power and the maximum charging power of the electric vehicle is calculated as the superposition power for distribution to make full use of the charging power of the charging station.

[0091] On the basis of the reference power, if some charging piles are in an unused state, the power share of the idle charging piles is averaged into the used charging piles as the superposition power. First, it can make full use of the circuit equipment of the charging station. Second, it can improve the charging efficiency and save the charging time. Further, on the basis of the above two power levels, a power transfer function is set so that the charging car owners can conduct power transfer transactions, so that the car owners in urgent need can obtain the maximum charging power, and the car owners who have waited for a long time can also get compensation, which can meet the actual needs of each vehicle party.

[0092] The solution of this application also has the following beneficial effects:

[0093] 1. By circularly detecting the number of idle charging piles and the power transfer information, the superposition power and the transfer power can be dynamically updated to realize the state linkage between each charging pile. When a certain charging pile is no longer in use, the reference power, superposition power and transfer power owned by the charging pile will all be released, and the superposition power and transfer power will be recalculated, and the superposition power and transfer power of each charging pile will be updated to realize the state linkage, improve the use efficiency of the charging power, and also try to reduce the use cost of the transfer power:

[0094] 1) For example, after the superposition power increases and meets the needs of the car owner, the car owner no longer needs to purchase the transfer power, reducing the charging cost.

[0095] 2) Or after the superposition power increases, the charging piles that did not participate in the transfer before can transfer the excess charging power due to the surplus power, which can not only reduce their own electricity consumption cost, but also enable the car owners in need to obtain higher charging efficiency.

[0096] 3) For example, because the purchase of electricity is greater than the sale of electricity, the purchase demand of electricity of some car owners can only be met by 80%. However, when a charging pile that also purchases electricity becomes idle, the share occupied by the charging pile is released, which can increase the proportion of electricity purchases of other car owners. For example, the original purchase of only 80% of the required power can be increased to 90% of the required power, or even 100%, or the supply exceeds the demand.

[0097] 2. This solution also has the following effects: when one or several charging piles are damaged, the charging piles are equivalent to being in an idle state, which does not affect the use of the total charging power of the charging station by other charging piles in the charging station, thereby maintaining a high charging power utilization rate.

[0098] To sum up, the charging power allocation scheme of the present application divides the power into levels and manages it in a way that can take into account basic fairness needs, the efficiency of charging stations and the personalized charging needs of car owners. It not only simplifies the power allocation calculation, but also can dynamically adjust the charging power of other charging piles, thereby improving personalized needs and flexibility.
