Description

[0002] With the rapid growth of electric vehicle ownership, the efficient use of charging infrastructure has become a key issue for the industry. Traditional charging stations often use fixed power allocation (such as allocating fixed power based on the order of access) or a simple "first-come, first-served" strategy. However, such methods are difficult to adapt to the complex scenario of multiple vehicles charging simultaneously: on the one hand, the remaining power of different vehicles varies significantly - low-power vehicles urgently need to be recharged, while high-power vehicles may occupy high power for a long time, resulting in resource mismatch; on the other hand, when new vehicles to be charged join or vehicles complete charging and leave, the remaining power of the charging station cannot be dynamically adjusted. Therefore, the current power allocation method wastes resources and has low charging efficiency. Summary of the Invention

[0007] After supplying power to each charging vehicle according to the primary allocated power, a target charging vehicle whose power demand is not met during the power supply process is identified in the charging vehicle set;

[0008] Based on the power difference between the power demand of each target charging vehicle and the allocated primary allocation power, as well as the updated current remaining charging power of the charging station, the secondary allocation power of each target charging vehicle is calculated, and the secondary allocation power is additionally provided to each target charging vehicle during the power supply process.

[0012] A target charging vehicle determination module is used to identify target charging vehicles whose power requirements are not met in the charging vehicle set after powering each charging vehicle according to the primary allocated power;

[0013] The second allocation module is used to calculate the secondary allocation power of each target charging vehicle based on the power difference between the power demand of each target charging vehicle and the allocated primary allocation power, as well as the updated current remaining charging power of the charging station, and to provide the secondary allocation power to each target charging vehicle in the power supply process.

[0028] Example 1

[0029] Figure 1 This is a flow chart of a power distribution method for a charging station, provided in Example 1 of the present invention. This method is specifically applicable to power distribution scenarios for charging piles at a charging station, and is particularly suitable for power distribution when the current remaining charging power at the charging station does not meet the power requirements of newly entered vehicles. This method can be implemented using a power distribution device for the charging station, which can be composed of software and / or hardware and configured in a computer or server of the charging station's power control system.

[0030] like Figure 1 As shown, including:

[0031] Step 110: When a new vehicle is detected to be connected to the charging station, it is detected whether the current remaining charging power of the charging station meets the power demand of the new vehicle.

[0032] Among them, the charging station includes multiple charging piles, which are used to charge multiple electric vehicles at the same time. When the electric vehicle is connected to the charging plug and starts charging, the charging pile can determine the rated power demand of the electric vehicle. Furthermore, the charging station includes a charging power upper limit. The charging power provided by each charging pile to each electric vehicle should not be greater than the charging power upper limit. The power demand is the rated charging power or rated input power of the electric vehicle. If the electric vehicle is charged at a charging power lower than the power demand, it will charge slowly. New vehicles are vehicles that have just been connected to the charging station. The remaining power of new vehicles is generally very low. Therefore, in order to ensure that their power is quickly restored, they can be given priority power supply to avoid low-power vehicles waiting for a long time and running out of power.

[0033] Specifically, after connecting to a charging station and starting charging, the charging station will determine whether the power requirements of the new vehicle can be met based on the current remaining charging power. If so, the charging power corresponding to the new vehicle's power requirements will be directly allocated to the new vehicle. However, due to the charging power limit of the charging station, there may be a situation where the current remaining charging power does not meet the power requirements of the new vehicle. Therefore, the charging power of each vehicle in the charging station needs to be allocated to ensure that the new vehicle can charge slowly.

[0034] Optionally, after detecting whether the current remaining charging power of the charging station meets the power requirement of the new vehicle, the method further includes:

[0035] If so, power is supplied to the new vehicle according to the power requirement of the new vehicle.

[0036] Specifically, if the current remaining charging power meets the power demand of the new vehicle, the new vehicle can be directly fully powered.

[0037] Step 120: If not, the new vehicle and the already charged vehicles in the charging station are grouped into a charging vehicle set, and the primary allocated power of each charging vehicle in the charging vehicle set is calculated based on the current remaining power and power demand of each charging vehicle.

[0038] Specifically, when a new vehicle is connected, if the current remaining charging power of the charging station is not enough to meet the power demand of the new vehicle alone, the new vehicle and the vehicles that are already in the charging state (vehicles being charged) in the charging station together form a charging vehicle set, and then calculate the one-time allocated power of each charging vehicle according to the current remaining power and power demand of each charging vehicle in the charging vehicle set. Among them, the one-time allocated power is the power value allocated to each vehicle in the charging vehicle set. The specific allocation method can be seen below. For example, the priority of each vehicle can be determined according to the current remaining power and power demand for allocation, or the corresponding allocation weight can be calculated according to the current remaining power and power demand, and then the power is allocated according to the allocation weight.

[0039] Step 130: After powering each charging vehicle according to the primary allocated power, identify target charging vehicles in the charging vehicle set whose power requirements are not met during the power supply process.

[0040] Specifically, after a power allocation, the charging power of each charging vehicle will be in two states: charging at the required charging power, or charging at a power lower than the required power. Therefore, for vehicles charging at a power lower than the required power, if the charging station still has some remaining charging power after the power allocation, the remaining charging power can be allocated to the target charging vehicle to ensure maximum resource utilization.

[0041] Optionally, the method for updating the current remaining charging power includes: calculating the total power of the charging station minus the first allocated power of each charging vehicle, and using the calculated value as the updated current remaining charging power of the charging station.

[0042] Step 140: Calculate the secondary distribution power for each target charging vehicle based on the power difference between the power demand of each target charging vehicle and the allocated primary distribution power, as well as the updated current remaining charging power of the charging station. Provide the secondary distribution power to each target charging vehicle during the power supply process.

[0043] For the identified target charging vehicles, the charging station management system will start the secondary allocation process. The core of this process is to recalculate the amount of power that should be added to each target vehicle based on the "unmet power amount" of the target charging vehicle (that is, the difference between its power demand and the primary allocated power) and the remaining allocable power after the charging station is updated (that is, the remaining available power after the primary allocation). Specifically, the system will give priority to vehicles with "larger unmet power amounts" or "lower power levels" (for example, a vehicle that still needs 200kW to meet demand and has less than 20% power will be given priority over another vehicle that still needs 100kW but still has 50% power). At the same time, the sum of the secondary allocated power of all target charging vehicles cannot exceed the remaining allocable power after the charging station is updated. Finally, the system adjusts the output power of the charging piles of each charging vehicle to add the secondary allocated power to the corresponding target charging vehicle until its power demand is met or the remaining power of the charging station is exhausted.

[0044] Optionally, when detecting that a vehicle is disconnected from the power supply connection of the charging station, detecting whether there is a power demand vehicle whose power demand is not met among the charged vehicles at the charging station;

[0045] If so, the newly allocated power for each power-demanding vehicle is calculated based on the power difference between the power demand of each power-demanding vehicle and the currently allocated power, as well as the updated current remaining charging power of the charging station, and the newly allocated power is additionally provided to each power-demanding vehicle during the power supply process.

[0046] A "charged vehicle" is an electric vehicle currently being charged at a charging station, but its charging process has not yet been completed. A "power-demanding vehicle" is a vehicle connected to a charging station but whose power demand has not been fully met. The power difference is the difference between a vehicle's power demand and its currently allocated power. The newly allocated power is the additional power allocated to a power-demanding vehicle, based on one or more existing allocations, to make up for the power difference.

[0047] Specifically, when a charging station detects a vehicle disconnected from the power supply, it triggers a power redistribution process: first, it identifies power-demanding vehicles among the currently charged vehicles whose actual received power does not meet their power requirements; based on the power difference between the power requirements of each power-demanding vehicle and the currently allocated power, and the remaining charging power after the charging station is updated (the power released due to vehicle disconnection), it calculates the "newly allocated power" required for each vehicle; finally, by adjusting the output of the charging pile, it adds the newly allocated power to the power-demanding vehicle until the power requirements of the charging vehicle are met or the remaining power is exhausted. This process can accurately supplement the needs of vehicles that have not yet completed charging, avoid idle power, and improve the utilization efficiency of charging station resources and the continuity of the charging process.

[0048] An embodiment of the present invention provides a power allocation method for a charging station. The method includes: upon detecting a new vehicle connecting to a charging station, detecting whether the current remaining charging power of the charging station meets the power requirements of the new vehicle; if not, grouping the new vehicle with each already charged vehicle in the charging station into a charging vehicle set, and calculating the primary allocation power for each charging vehicle based on the current remaining power and power requirements of each charging vehicle in the charging vehicle set; after powering each charging vehicle according to the primary allocation power, identifying target charging vehicles in the charging vehicle set whose power requirements were not met during the power supply process; calculating the secondary allocation power for each target charging vehicle based on the power difference between the power requirements of each target charging vehicle and the allocated primary allocation power, as well as the updated current remaining charging power of the charging station, and providing the secondary allocation power additionally to each target charging vehicle during the power supply process. Specifically, calculating the primary allocation power for each charging vehicle based on the current remaining power and power requirements of each charging vehicle allows for reasonable power allocation for vehicles with low power. At the same time, the secondary allocation power for each target charging vehicle can ensure the full use of electric power and resource utilization.

[0049] Example 2

[0050] Figure 2 This is a flow chart of a power distribution method for a charging station provided by an embodiment of the present invention. The method is based on the above embodiments and further defines the calculation method of the primary distribution power and the secondary distribution power.

[0051] like Figure 2 As shown, including:

[0052] Step 210: When a new vehicle is detected to be connected to the charging station, it is detected whether the current remaining charging power of the charging station meets the power demand of the new vehicle.

[0053] Step 220: For any charging vehicle in the charging vehicle set, determine a current allocation weight based on the power demand and current remaining power of the charging vehicle; wherein the current allocation weight is inversely proportional to the current remaining power and directly proportional to the power demand.

[0054] The current allocation weight is used to determine the allocation ratio of charging vehicles to charging station power.

[0055] Specifically, to address the existing problem of low-battery vehicles urgently needing to recharge, while high-battery vehicles may occupy high power for extended periods, leading to resource mismatch, current allocation weights can be determined based on the power requirements and current remaining power of the charging vehicles. Furthermore, the current allocation weights are inversely proportional to the current remaining power to ensure that low-battery vehicles receive more charging power, and directly proportional to the power requirements to ensure that high-power vehicles receive more charging power.

[0056] For example, the current allocation weight of the charging vehicle can be calculated by: W(i)=(100-SOC i )×Pdemand(i). Among them, SOC i is the current remaining power of the i-th vehicle, and Pdemand(i) is the power demand of vehicle i.

[0057] Step 230: Calculate the first allocated power of each charging vehicle according to the total power of the charging station, the current allocation weight of each charging vehicle, and the power demand of each charging vehicle.

[0058] Specifically, you can use P1 i = min[Pdemand(i), Ptotal×W(i) / Wtotal] determines the first allocated power P1 of charging vehicle i i , where Pdemand(i) is the power demand, Ptotal is the total power of the charging station, W(i) is the current allocation weight, and Wtotal is the sum of the current allocation weights of each charging vehicle.

[0059] Optionally, the candidate first allocation power of each charging vehicle is determined based on the current allocation weight of each charging vehicle and the total power of the charging station; for any charging vehicle, the smaller value of the candidate first allocation power of the charging vehicle and the power demand of the charging vehicle is determined as the first allocation power of the charging vehicle.

[0060] The candidate first allocated power is a theoretical value of the total power of the charging station allocated according to the weight, and the candidate first allocated power corresponds to Ptotal×W(i) / Wtotal in the above formula.

[0061] It should be noted that the candidate first allocated power value is greater than the power demand of the charging vehicle, but the ideal charging power of the charging vehicle is Pdemand(i). In this case, the smaller value of Pdemand(i) and Ptotal×W(i) / Wtotal should be selected as the first allocated power for the charging vehicle. If the candidate first allocated power value is less than the power demand of the charging vehicle, this indicates that the overall power of the charging station may not be able to support full charging of all charging vehicles. Therefore, it is necessary to sacrifice the charging power of some charging vehicles to enable them to charge at a lower power.

[0062] Step 240: After powering each charging vehicle according to the primary allocated power, identify target charging vehicles in the charging vehicle set whose power requirements are not met during the power supply process.

[0063] Specifically, according to the allocated power, each charging vehicle is supplied with power. There are two situations for the charging vehicle. The first is that the charging vehicle is fully charged according to its own power demand. The other is that the power demand is not met and low-power charging is performed.

[0064] At this time, because the allocation rule itself takes the minimum value between the candidate first allocation power and the power demand, it is possible that the total power of the charging station is not fully allocated. Therefore, the charging station will have excess charging power. In this case, the excess charging power can be allocated to the target charging vehicles whose power demand is not met to avoid wasting resources.

[0065] Step 250: Calculate the power difference between the power demand of each target charging vehicle and the allocated primary allocation power as the first alternative power of each target charging vehicle; and calculate the second alternative power of each target charging vehicle based on the current allocation weight of each target charging vehicle, the sum of the current allocation weights of each charging vehicle in the charging vehicle set, and the current remaining charging power.

[0066] Exemplarily, the second allocated power may be determined by the following formula:

[0067] P2(i) = min[Pdemand(i) - P1(i), Pleft × W(i) / W(U)], where Pdemand(i) and P1(i) are the power demand and first allocated power of charging vehicle i, respectively. Pleft is the current remaining charging power, and W(i) and W(U) are the current allocated weight and total weight of the charging vehicles, respectively.

[0068] Step 260: For any target charging vehicle, determine the smaller value between the first alternative power of the target charging vehicle and the second alternative power of the charging vehicle as the second allocated power of the target charging vehicle.

[0069] Specifically, to prevent each second allocated power from exceeding the current remaining charging power, the smaller value between the first alternative power and the second alternative power of the charging vehicle should be selected as the second allocated power of the target charging vehicle.

[0070] Step 270: During the power supply process, the secondary distributed power is additionally provided to each target charging vehicle.

[0071] Specifically, during the power supply process, the secondary distributed power will be additionally provided to each target charging vehicle to ensure full utilization of all power at the charging station, thereby improving charging efficiency.

[0072] Optionally, when detecting that a vehicle is disconnected from the power supply connection of the charging station, detecting whether there is a power demand vehicle whose power demand is not met among the charged vehicles at the charging station;

[0073] If so, the newly allocated power for each power-demanding vehicle is calculated based on the power difference between the power demand of each power-demanding vehicle and the currently allocated power, as well as the updated current remaining charging power of the charging station, and the newly allocated power is additionally provided to each power-demanding vehicle during the power supply process.

[0074] A vehicle disconnected from a charging station refers to a state where the electric vehicle no longer draws power from the charging station's charging pile, either because the vehicle has completed charging, the user has actively unplugged the charger, or due to a malfunction. At this point, the vehicle exits the charging station's "connected vehicles" list, and the charging power it occupied is released back to the charging station's total power pool. A charged vehicle is an electric vehicle that is still connected to the charging station's charging pile and charging (a vehicle that has not yet completed charging). These vehicles may have been charging for some time but have not yet reached full charge. Power-demanding vehicles with unmet power requirements are some of the charged vehicles whose actual allocated charging power is lower than their power requirements due to the charging station's total power limit (e.g., other vehicles charging simultaneously occupying power). Newly allocated power refers to the power released after a vehicle disconnects and releases power. The charging station allocates this released power (i.e., the updated remaining charging power) to "power-demanding vehicles" that still require more power to make up for their previous power difference. The newly allocated power is the value of this additional power allocation.

[0075] When it is detected that a vehicle is disconnected from the power supply of the charging station, the system triggers the power redistribution process: first, it checks whether there are any vehicles whose power requirements are not met among the currently connected charged vehicles (that is, vehicles whose actual allocated power is lower than the rated demand); if so, the system calculates the newly allocated power for each vehicle based on the power difference of each vehicle (the difference between the rated power demand and the currently allocated power) and the remaining charging power after the charging station is updated (the power released by the disconnected vehicle); finally, by adjusting the output of the charging pile, the newly allocated power is added to these vehicles whose requirements are not met, so as to make up for their power gap as much as possible, avoid idle power, and improve the utilization rate of the charging station's power resources.

[0076] The method of the embodiment of the present invention can ensure rapid charging of low-power charging vehicles by performing a primary power allocation to each charging vehicle. Secondary power allocation to target charging vehicles whose power requirements are not met can improve the utilization rate of the charging power of the charging vehicles.
