Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging technology, and in particular to a method and system for allocating off-peak electricity time slots for low-power multi-gun charging piles. Background Technology

[0002] With the rapid growth in the number of new energy vehicles, the contradiction between supply and demand for charging facilities in residential areas is becoming increasingly prominent. Older residential areas generally suffer from limited power distribution capacity and parking shortages, making it difficult to build new charging piles on a large scale. The traditional "one pile, one gun" model not only occupies a lot of space, but also has an average utilization rate of less than 20% during the nighttime half-price period, resulting in serious waste of resources.

[0003] The core pain point of the existing model is that users typically start charging during off-peak hours at 10 PM. After the vehicle is fully charged, most users are asleep and cannot manually switch charging guns, resulting in the charging station remaining idle for the rest of the time. At the same time, existing multi-gun technologies are mostly designed for high-power fast charging scenarios, with complex control logic and high costs. They do not fully integrate with residential peak and off-peak electricity pricing policies and dynamic changes in user demand, and cannot flexibly switch between shared charging by multiple users and continuous charging by a small number of users. Summary of the Invention

[0004] To address the aforementioned issues, a method and system for allocating off-peak electricity time slots for low-power multi-gun charging piles are provided, aiming to resolve the problems existing in the prior art.

[0005] The specific technical solution is as follows:

[0006] The method for allocating off-peak electricity time slots for low-power multi-gun charging piles includes the following steps:

[0007] S1. Divide the off-peak electricity hours at night into multiple time slots;

[0008] S2. Generate corresponding sub-orders according to the order in which user orders are created. The total time slices occupied by all sub-orders shall not exceed the maximum time slice limit for this single night.

[0009] S3. Assign a corresponding basic order weight to each sub-order based on the order in which the sub-orders are created;

[0010] S4. Assign queue priority to the corresponding sub-orders based on the user's selection;

[0011] S5. When the charging is completed and the payment is settled, the corresponding final fee is generated based on the basic order weight and the queue-jumping weight of the sub-order.

[0012] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: step S4 further includes:

[0013] S41. When a sub-order is created, the user can choose a specified time slice or a random time slice;

[0014] S42. If the user selects a random time slice, the sub-orders will be arranged in order of their creation time. If the user selects a specific time slice, proceed to S43.

[0015] S43. Determine whether the corresponding specified time slot is occupied. If the corresponding time slot is not occupied, then the sub-order will be scheduled into the corresponding time slot. If the corresponding time slot is occupied, proceed to step S44.

[0016] S44. Determine whether the occupied time slice is selected in the specified mode. If it is in the specified mode, the time slice is not selectable. If it is not in the specified mode, the time slice is in the queue-jumping state, and the sub-order is assigned a queue-jumping weight. The queue-jumping sub-order is converted to the time slice corresponding to the queue-jumping sub-order, and the weight of the sub-order is adjusted to the corresponding weight.

[0017] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: the specific method for dividing the time slots in step S1 is to divide the off-peak electricity time at night into multiples of X time slots based on the number of charging guns X set in this charging pile.

[0018] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following characteristic: within each time slot, all the power of the charging pile is supplied to the charging gun of the corresponding sub-order, while the other charging guns are in a waiting state.

[0019] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: the specific weight of each time slot in step S3 is N for the first time slot, N-1 for the second time slot, N-2 for the third time slot, and so on up to 1 for the Nth time slot.

[0020] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: when a sub-order occupies two time slots, the basic order weight of the sub-order is based on the weight of the earlier time slot.

[0021] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: the calculation method for the queue-jumping weight recorded in step S44 is as follows: obtain the establishment order value K of the sub-order; obtain the order value L of the sub-order corresponding to the queue-jumped time slot; calculate the queue-jumping span M=LK, and the queue-jumping weight is M.

[0022] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: in step S44, the final weight of the queue-jumping sub-order is the basic order weight plus the queue-jumping weight.

[0023] The above-mentioned method for allocating off-peak electricity time slots for low-power multi-gun charging piles also has the following feature: the final rate in step S5 is calculated by adjusting the rate according to the final weight of the sub-order, and the final cost = basic cost * adjusted rate.

[0024] The low-power multi-gun charging pile off-peak electricity time-slot allocation system applies the above allocation scheme and includes a low-power charging pile, a user terminal, and a cloud service platform. The low-power charging pile is equipped with multiple charging guns, the user terminal is used to allocate the output of multiple charging guns in time slots, and the charging pile is connected to the cloud service platform through the user terminal.

[0025] In summary, the beneficial effects of this scheme are:

[0026] The low-power multi-gun charging pile off-peak electricity time slot allocation method and system provided by this invention allows users to independently select charging time slots, enabling more vehicles to enjoy off-peak electricity discounts and minimizing off-peak electricity waste. The low-power multi-gun charging pile off-peak electricity time slot allocation method and system provided by this invention optimizes charging allocation logic and avoids resource waste.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0030] The present invention will be further described below with reference to specific embodiments, but these are not intended to limit the scope of the invention.

[0031] Figure 1 This is a flowchart of the low-power multi-gun charging pile off-peak electricity time slot allocation method of the present invention, as shown below. Figure 1 As shown in this embodiment, the method for allocating off-peak electricity time slots for low-power multi-gun charging piles includes the following steps:

[0032] S1. Divide the off-peak electricity hours at night into multiple time slots;

[0033] S2. Generate corresponding sub-orders according to the order in which user orders are created. The total time slices occupied by all sub-orders shall not exceed the maximum time slice limit for this single night.

[0034] S3. Assign a corresponding basic order weight to each sub-order based on the order in which the sub-orders are created;

[0035] S4. Assign queue priority to the corresponding sub-orders based on the user's selection;

[0036] S5. When the charging is completed and the payment is settled, the corresponding final fee is generated based on the basic order weight and the queue-jumping weight of the sub-order.

[0037] In the above embodiment, step S4 further includes:

[0038] S41. When a sub-order is created, the user can choose a specified time slice or a random time slice;

[0039] S42. If the user selects a random time slice, the sub-orders will be arranged in order of their creation time. If the user selects a time slice, proceed to S43.

[0040] S43. Determine whether the corresponding specified time slot is occupied. If the corresponding time slot is not occupied, then the sub-order will be scheduled into the corresponding time slot. If the corresponding time slot is occupied, proceed to step S44.

[0041] S44. Determine whether the occupied time slice is selected in the specified mode. If it is in the specified mode, the time slice is not selectable. If it is not in the specified mode, the time slice is in the queue-jumping state, and the sub-order is assigned a queue-jumping weight. The queue-jumping sub-order is converted to the time slice corresponding to the queue-jumping sub-order, and the weight of the sub-order is adjusted to the corresponding weight.

[0042] In the above embodiment, the specific method for dividing the time slices in step S1 is to divide the off-peak electricity time at night into multiples of X time slices based on the number of charging guns X set in this charging pile.

[0043] It should be noted that, based on the current status of parking spaces, each charging station can correspond to a maximum of four parking spaces. Therefore, in practical applications, each charging station is generally equipped with four charging guns.

[0044] In the above embodiment, the full power of the charging pile is supplied to the charging gun of the corresponding sub-order in each time slice, and the other charging guns are in a waiting state.

[0045] In the above embodiment, the specific weight of each time slice in step S3 is N for the first time slice, N-1 for the second time slice, N-2 for the third time slice, and so on up to 1 for the Nth time slice.

[0046] In the above embodiments, when a sub-order occupies two time slices, the basic order weight of the sub-order is based on the weight of the earlier time slice.

[0047] In the above embodiment, the method for calculating the queue-jumping weight recorded in step S44 is as follows: obtain the establishment order value K of this sub-order; obtain the order value L of the sub-order corresponding to the queue-jumping time slice; calculate the queue-jumping span M=LK, and the queue-jumping weight is M.

[0048] In the above embodiment, in step S44, the final weight of the queue-jumping sub-order is the basic order weight plus the queue-jumping weight.

[0049] It should be noted that a compensation weight can also be set. When a sub-order is interrupted, its final fee rate = basic order weight - compensation weight, and the compensation weight = interrupted span - 1.

[0050] In the above embodiment, the final fee rate in step S5 is calculated by adjusting the fee rate according to the final weight of the sub-order, and the final fee = basic fee * adjusted fee rate.

[0051] It should be noted that the base fee includes the base electricity fee and the base service fee. The base fee is determined based on the charging duration. Each time slot contains the same amount of charging time. Therefore, when a sub-order occupies multiple time slots, its base fee will increase accordingly.

[0052] The low-power multi-gun charging pile off-peak electricity time-slot allocation system includes a low-power charging pile, a user terminal, and a cloud service platform. The low-power charging pile is equipped with multiple charging guns, and the user terminal is used to allocate the output of multiple charging guns in time slots. The charging pile is connected to the cloud service platform through the user terminal.

[0053] It should be noted that the user terminal can wirelessly connect to the user's mobile phone, so that the user can remotely make reservations, pay, or monitor the charging status.

[0054] It should also be noted that the status of each charging station is uploaded to the cloud service platform. When all time slots of one charging station are occupied and the charging station receives a charging reservation request, the cloud service platform transmits the location information of nearby available charging stations to the user terminal and the user's mobile phone that made the reservation request.

[0055] Working principle: This solution is mainly applied to private charging piles in residential communities. If one charging pile is built for each parking space, it will result in too many charging piles occupying space. Moreover, many vehicles do not need to occupy all the time for charging at night. This solution allocates the entire off-peak electricity time at night and presets multiple charging guns to take turns outputting, making full use of off-peak electricity time and avoiding waste. In addition, this solution also sets basic order weights and queue-jumping weights that are linked to charging fees, ensuring the operating efficiency of charging piles while meeting the needs of users as much as possible.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the content of this specification should be included within the protection scope of the present invention.
