Description

Technical Field

[0001] This application relates to the technical field of battery swapping, and specifically relates to a battery swapping scheduling control method, a computer-readable storage medium, and a computer device. Background Art

[0002] The methods for replenishing energy for the batteries of vehicles mainly include two types: battery swapping and charging. Among them, battery swapping realizes the replenishment of energy for vehicles by directly replacing the depleted battery with a fully charged battery. Since this method can quickly replenish energy, it has been favored by vehicle owners. The process of swapping the battery for a vehicle in a battery swapping station is generally as follows: after driving the vehicle into the parking platform in the battery swapping station, the fixing bolts on the depleted battery of the vehicle to be swapped are loosened by the battery swapping moving mechanisms such as unlocking and locking gun heads in the battery swapping station, so as to remove the depleted battery (and then store the depleted battery in the charging bin of the battery swapping station for charging), and install the fully charged battery in the battery swapping station onto the vehicle to be swapped.

[0003] In order to meet the energy replenishment needs of vehicles, battery swapping stations often strongly rely on the power grid, which will, to a certain extent, cause the phenomenon of power grid instability (such as local power shortages caused by raising the peak value of the power grid to a certain extent). In addition, due to the attributes of the power grid itself, such as electricity price fluctuations and the corresponding relationship between the electricity consumption load and time periods, it will also cause fluctuations in the battery swapping cost (such as a significant increase in the battery swapping cost during high electricity price periods), which will also affect the popularization and application of battery swapping services to a certain extent, such as the operation cost of the battery swapping station and the battery swapping cost of (single) battery swapping services will fluctuate to a certain extent. By introducing new input sources of power for battery swapping stations, the diversification of the input sources of power for battery swapping stations can be realized. Based on this, it is expected to reduce the dependence of battery swapping stations on the power grid, thereby stabilizing the operation cost of battery swapping stations and the battery swapping cost of (single) battery swapping services as much as possible. However, there is still room for improvement in how to reasonably configure the power grid and one or more newly introduced input sources of power for battery swapping stations. Summary of the Invention

[0004] This application aims to at least partly solve the above technical problems and / or solve at least part of the above technical problems. Specifically, on the basis of diversifying the input sources of power for battery swapping stations, how to reasonably configure the power grid and one or more newly introduced input sources of power for battery swapping stations to stabilize the operation cost of battery swapping stations and the battery swapping cost of single services as much as possible, so as to optimize the battery swapping performance of battery swapping stations on the premise of reducing the dependence of battery swapping stations on the power grid.

[0005] In a first aspect, the present application provides a method for controlling the swapping power scheduling. The swapping power station is configured with a station-built energy storage system, an energy storage device, and a power battery. The control method includes: receiving a swapping power request; determining whether to adjust a preset power charging and storage strategy according to the swapping power request; wherein, in the preset power charging and storage strategy, it includes: charging the power battery from the power grid and / or the energy storage device; wherein, the power grid and / or the station-built energy storage system can store electricity in the energy storage device.

[0006] With such a configuration, it is possible to seek to reduce the dependence of the swapping power station on the power grid by introducing the station-built energy storage system.

[0007] For the above-mentioned method for controlling the swapping power scheduling, in a possible implementation manner, the "charging the power battery from the power grid and / or charging the power battery from the energy storage device" includes: determining the first power demand of the power battery; determining the second power demand of the energy storage battery; charging the power battery from the power grid and / or charging the power battery from the energy storage device to meet the power consumption demand corresponding to the first power demand; charging the energy storage device from the power grid and / or charging the energy storage device from the station-built energy storage system to meet the power consumption demand corresponding to the second power demand.

[0008] With such a configuration, by determining the power supply strategy with the energy storage device as the power consumption side, the reliability of the power supply is ensured. On this basis, by using the energy storage device as the power supply side, the quality of the swapping power service of the swapping power station is ensured.

[0009] It should be noted that in the case where the power grid participates in the swapping power scheduling mechanism, it should be understood that: the external power grid can be introduced into the present application and participate in the swapping power scheduling mechanism.

[0010] For the above-mentioned method for controlling the swapping power scheduling, in a possible implementation manner, the "charging the power battery from the power grid and / or charging the power battery from the energy storage device to meet the power consumption demand corresponding to the first power demand" includes: charging the power battery from the power grid and / or charging the power battery from the energy storage device according to the power trading cost of the power grid to meet the power consumption demand corresponding to the first power demand; in the step of "charging the energy storage device from the power grid and / or charging the energy storage device from the station-built energy storage system to meet the power consumption demand corresponding to the second power demand", it includes: charging the energy storage device from the power grid and / or the energy storage device according to the power trading cost of the power grid to meet the power consumption demand corresponding to the second power demand.

[0011] With such a configuration, it is possible to seek to reduce the swapping power cost to a certain extent. For example, the power trading cost may include but is not limited to fluctuations in electricity prices, fines for exceeding the power distribution report for electricity consumption, etc.

[0012] For the above battery swapping scheduling control method, in a possible implementation, the step of "charging the energy storage device from the power grid and / or charging the energy storage device from the on-site energy storage system to meet the power consumption demand corresponding to the second power demand" includes: determining whether the on-site energy storage system can meet the power consumption demand corresponding to the second power demand; if not, charging the energy storage device from the power grid and the on-site energy storage system.

[0013] With such a configuration, it is possible to ensure the power supply level of the energy storage device. For example, based on the preference for the on-site energy storage system, the power grid can be made to charge the energy storage battery in the low-price range as much as possible with reference to the power trading cost. However, in the case where the battery swapping service is affected, the factor of power trading cost can also be appropriately discarded (which belongs to the category of adjusting the power storage strategy).

[0014] For the above battery swapping scheduling control method, in a possible implementation, the step of "determining whether to adjust the preset power charging and storage strategy according to the battery swapping request" includes: in the case where the second power demand of the energy storage battery can be met but the first power demand of the power battery cannot be met, adjusting the preset power charging and storage strategy as follows: changing the step of "charging the power battery from the power grid and / or charging the power battery from the energy storage device to meet the power consumption demand corresponding to the first power demand" to: charging the power battery from the power grid and / or the on-site energy storage system to meet the power consumption demand corresponding to the first power demand.

[0015] With such a configuration, it is possible to ensure the power supply reliability of the power battery by establishing a direct power supply relationship between the on-site energy storage system and the power battery.

[0016] For the above battery swapping scheduling control method, in a possible implementation, the step of "determining whether to adjust the preset power charging and storage strategy according to the battery swapping request" includes: in the case where the second power demand of the energy storage battery is excessive but the first power demand of the power battery cannot be met, adjusting the preset power charging and storage strategy as follows: changing the step of "charging the power battery from the power grid and / or charging the power battery from the energy storage device to meet the power consumption demand corresponding to the first power demand" to: at least charging the power battery from the energy storage device to meet the power consumption demand corresponding to the first power demand.

[0017] With such a configuration, it is possible to further reduce the dependence of the battery swapping station on the power grid. For example, only by feeding power from the energy storage device to the power battery to meet the power consumption demand corresponding to the first power demand.

[0018] For the above battery swapping scheduling control method, in a possible implementation manner, the step of "determining whether to adjust a preset power charging and storage strategy according to the battery swapping request" includes: in a case where the first power demand of the power battery and the second power demand of the energy storage battery cannot be satisfied, adjusting the preset power charging and storage strategy in the following manner: causing the power grid to charge the power battery additionally to at least partly satisfy the power consumption demand corresponding to the first power demand; and / or causing the power grid to charge the energy storage device additionally to at least partly satisfy the power consumption demand corresponding to the second power demand.

[0019] With such a configuration, it is possible to ensure the stability of the power charging and storage strategy even in the case of the current battery swapping insertion.

[0020] It should be noted that the "additionally" mentioned here should be understood as follows: in the previous power charging and storage strategy, the introduction of the power grid may need to consider factors such as electricity price cost and priority of the station-built energy storage system. However, when the power supply capacity of the power charging and storage strategy is unstable, these preset factors need to be discarded. For example, the power grid and the energy storage device are directly used to charge the power battery at the same time, only the power grid is used to charge the power battery, or the power grid is directly used to charge the energy storage device, etc., to ensure the battery swapping service level of the battery swapping station.

[0021] For the above battery swapping scheduling control method, in a possible implementation manner, the step of "causing the power grid to charge the power battery additionally to at least partly satisfy the power consumption demand corresponding to the first power demand; and / or causing the power grid to charge the energy storage device additionally to at least partly satisfy the power consumption demand corresponding to the second power demand" includes: obtaining the priorities of the power battery and the energy storage device; causing the power grid to charge the power battery or the energy storage device with a higher priority additionally to at least satisfy the power consumption demand corresponding to the first power demand of the power battery with a higher priority or the second power demand of the energy storage device.

[0022] With such a configuration, it is possible to ensure the service level of the battery swapping station. Exemplarily, in the case of battery swapping priority, the power grid is caused to charge the power battery to ensure the battery swapping level. At the same time, the energy storage device can be selectively charged to a certain extent to balance the battery swapping service level and cost issues of the battery swapping station.

[0023] In a second aspect, the present application further provides a computer-readable storage medium. The storage medium includes a memory, and the memory is adapted to store a plurality of program codes, and the program codes are adapted to be loaded and run by a processor to execute the foregoing battery swapping scheduling control method.

[0031] The present application will be described below with reference to the drawings in combination with a station-built energy storage system for a photovoltaic system. In the drawings:

[0032] Figure 1 A flowchart showing the power swapping scheduling control method according to an embodiment of the present application. Detailed Embodiments

[0033] The preferred embodiments of the present application will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0034] It should be noted that in the description of this application, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] In addition, it should also be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can also be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In addition, to better illustrate this application, numerous specific details are given in the following specific implementation manners. Those skilled in the art should understand that this application can also be implemented without certain specific details. In some instances, the battery swapping process, principle, etc. of the battery swapping station well-known to those skilled in the art are not described in detail to highlight the main idea of this application.

[0037] Exemplarily, the battery swapping station includes a parking platform. When a vehicle drives into the parking platform inside the battery swapping station, battery swapping operations such as removing the depleted battery and installing a fully charged battery can be performed on the vehicle through battery swapping motion mechanisms such as unlocking and locking the gun head (it should be noted that the fully charged battery here should be understood as: compared with the depleted battery, a battery with a certain amount of electricity that can provide at least a certain degree of battery swapping value for users (usually with more electricity, such as 80%, 100% of the full charge capacity, etc.)). Exemplarily, an opening and closing door is provided at the bottom of the parking platform. For example, when the vehicle reaches the position for battery swapping operation, the opening and closing door at the bottom opens, and the battery swapping motion mechanism and the like can perform battery swapping operations from below the opening and closing door.

[0038] Exemplarily, in addition to the power grid, the input sources of the power for the battery swapping station that can be introduced can include, but are not limited to: the station-built energy storage system, such as a system that can collect renewable clean energies such as solar energy and wind energy (in this example, the station-built energy storage system is a photovoltaic system that can collect light energy); the energy storage device configured in the battery swapping station (such as energy storage batteries of different scales. The energy storage device has the advantages that the storage and release of electric energy can be asynchronous, and the release of electric energy is stable, etc., so it can achieve peak shaving and valley filling to a certain extent, and through necessary supplementation, the reliability of the battery swapping service can be ensured).

[0039] The present application will be described below in connection with the case where the swapping station is configured with a photovoltaic system and an energy storage device (energy storage battery). Specifically, how to configure the input sources of the three types of power for the swapping station, namely the power grid, the newly introduced photovoltaic system, and the energy storage device, to improve the swapping level of the swapping station. Obviously, those skilled in the art can determine the scale of the photovoltaic system / energy storage device, the layout method of the photovoltaic system, etc. according to actual needs, and can also add systems for collecting other renewable / non-renewable resources such as wind energy and water energy (the gravitational potential energy of water) on the basis of the photovoltaic system.

[0040] Among them, the photovoltaic system can convert the collected solar energy into electrical energy and can directly or indirectly supply electrical energy directly to any load including the batteries in the swapping station. Among them, the power generation level of the photovoltaic system is affected by factors such as weather.

[0041] Among them, the energy storage device can store electrical energy from the power grid and the photovoltaic system and can directly supply electrical energy to any power-consuming end including the batteries in the swapping station and the vehicles to be served. The energy storage device has the characteristics of being able to supply power to the power-consuming end stably and flexibly. However, it is necessary to store electrical energy in place in advance. For example, it can be stored through the power grid or the on-site energy storage system.

[0042] Compared with the newly introduced photovoltaic system and energy storage device, the power grid can meet the power demand level of the swapping station to a greater extent. However, the power grid has constraint factors such as variable electricity prices and the principle that the pre-declared upper limit is not allowed to be exceeded. Specifically, since the method of using the power grid to supply power to the power-consuming end of the swapping station needs to participate in power trading, and since the electricity price of the power grid has differences in forms such as peak price and valley price, taking the battery related to swapping as an example of the power-consuming end, the method of using the power grid to supply power can be intuitively reflected as the difference in swapping costs. In this way, it is expected to achieve peak shaving and valley filling to a certain extent through the supplement of the on-site energy storage system (or the cooperation between the on-site energy storage system and the power grid), so as to ensure the stability of the swapping cost as much as possible. In addition, as the power-consuming party, when the actual electricity consumption generated by the swapping station exceeds the power demand declared during power distribution, it may be fined by the power supply party. And it may also affect the power supply stability of the load group of the power grid. Therefore, through the supplement of the on-site energy storage system (or the cooperation between the on-site energy storage system and the power grid), in addition to stabilizing the swapping cost, it can also reduce / eliminate the impact of the load group of the power grid to a certain extent.

[0043] Among the electricity demands in the swapping station, the electricity demand related to swapping is realized by charging the power battery, and other ordinary electricity demands can be realized through the energy storage device, the power grid, and the photovoltaic system, such as directly through the energy storage device.

[0044] Among them, a preset power charging and storage strategy (predicted) can be determined based on the power demand in the battery swap station. Based on this, when a battery swap request is inserted, it is judged that the power charging and storage strategy can meet the current power demand. If so, continue to operate according to the preset power charging and storage strategy. If not, the power charging and storage strategy should be appropriately adjusted to ensure the battery swap service level of the battery swap station.

[0045] For example, the power demand in the battery swap station mainly includes:

[0046] 11) The power demand of the power battery (first demand).

[0047] For example, each day (24 hours) can be divided into several time series (such as t1-tN), and the user's battery replacement demand corresponding to each time series (such as the distribution probability of user battery replacement, etc.) can be counted. Based on this, the user's battery replacement demand can be converted into the required number of power batteries. In other words, the mapping relationship between the time series and the distribution probability of user battery replacement is converted into the mapping relationship between the time series and the number of power batteries. In this way, the power demand corresponding to the battery replacement demand of a certain time series can be described in terms of how many (which) power batteries need to be charged. For example, in t1-tN, P1-PN power batteries need to be charged respectively, and the required power is Q1-QN respectively. For example, for ti in the time series, 3 power batteries need to be charged, and the required power Qi=0.3Q0+0.7*2Q0, where Q0 is the power required to fully charge the depleted power battery. In this way, the mapping relationship between the time series and the power demand of the power battery can be determined.

[0048] Obviously, the above calculation / expression method is only an exemplary description. For example, the type of power battery and other aspects are simplified in the calculation process. Obviously, those skilled in the art can flexibly adjust it according to actual needs and thereby determine the power demand of the power battery.

[0049] 12) The power demand of the energy storage battery (second demand).

[0050] The uses of energy storage batteries mainly include two aspects. On the one hand, they participate in electricity trading, such as supplying electricity to electricity demanders when the power grid electricity price is high, which has the effect of shaving peaks and filling valleys to a certain extent. On the other hand, they supplement the fixed electricity demand of electricity demanders. For example, if the electricity demander's electricity consumption exceeds the electricity demand declared at the time of power distribution, he will be fined by the power grid. At this time, energy storage batteries can be used to supplement it in combination with the current electricity demand. For example, at one or more preset time nodes / intervals, energy storage batteries can be used to balance expenses and control the use of State Grid electricity as much as possible to avoid fines.

[0051] Similar to the aforementioned power battery, the mapping relationship between the time series and the power consumption demand of the energy storage battery can also be determined. Exemplarily, in t1 - tN, the power consumption demands of the energy storage battery are q1 - qN respectively. Exemplarily, for tj in the time series, the power consumption demand qj of the energy storage battery = 1.7 * q0, where q0 is the power required to fully charge a unit energy storage battery. In this way, the mapping relationship between the time series and the power consumption demand of the power battery can be determined. Similarly, those skilled in the art can flexibly adjust the calculation / expression method according to actual needs and thus determine the power demand of the energy storage battery.

[0052] If the power demands of the calculated power battery and the energy storage battery are integrated, the power demand of the power exchange station can be determined. Based on this, a preset power storage strategy can be formulated to minimize costs and the power exchange station's dependence on the power grid while meeting the current power demand.

[0053] The preset power storage strategy mainly includes two aspects: the supply quantity and the supply source of the power supply, where:

[0054] 21) Configuration of the supply quantity:

[0055] In general, the power demand for time t is configured at time series t - 1. Exemplarily, assuming that the calculated power demand for time series t is Qt + qt, then a power supply of Qt + qt is configured at time series t - 1. Here, Qt and qt respectively represent the power demands of the power battery and the energy storage battery corresponding to time series t. In this way, the service level of the power exchange station can be ensured.

[0056] 22) Selection of the supply source:

[0057] The selection of the supply source takes into account requirements such as electricity price information and battery maintenance. For example, for battery maintenance, the power battery is charged with a low current. For the requirement of battery maintenance, the total power demand does not decrease but the charging time increases. In this way, the power distribution amount corresponding to each time series will change. Therefore, for the known power demand, it is calculated according to its charging time. On the premise of considering both the power demand and the charging time, the charging cost is also considered to determine the power replenishment mechanism of the power battery.

[0058] In this example, the on-site energy storage system of the station is a photovoltaic system. For example, the power generation capacity of the photovoltaic system can be predicted with reference to the weather conditions of the next day. The power generated by the photovoltaic system is by default arranged for the energy storage battery. For example, it is default that the electric energy generated by the photovoltaic system is directly supplied to the energy storage battery for use. Only in the case where the energy storage battery is full / surplus / faulty and cannot store electricity, will the power battery be directly charged. In the case where the power of the photovoltaic system is insufficient, the power grid can be used for supplementation. By default, the energy storage battery is supplemented with electricity during the valley price period (valley price range). If it is not possible to fully charge the energy storage battery in the nearby valley price range, the available time can be searched in the previous valley price range according to the required time of the electricity.

[0059] In a possible implementation manner, the preset power charging and storage strategy includes:

[0060] Enable the power grid to charge the power battery and / or the energy storage device to charge the power battery;

[0061] Among them, the power grid and / or the on-site energy storage system of the station can store electricity in the energy storage device.

[0062] For example, in an ideal state, without relying on the power grid at all, the on-site energy storage system of the station stores electricity in the energy storage device, and the energy storage device charges the power battery.

[0063] In a possible implementation manner, enabling the power grid and / or the energy storage device to charge the power battery specifically includes:

[0064] Determine the first power demand of the power battery;

[0065] Determine the second power demand of the energy storage battery;

[0066] Enable the power grid to charge the power battery and / or the energy storage device to charge the power battery to meet the power consumption demand corresponding to the first power demand;

[0067] Enable the power grid to charge the energy storage device and / or the on-site energy storage system of the station to charge the energy storage device to meet the power consumption demand corresponding to the second power demand.

[0068] In this way, by better planning the way of forming the power charging and storage strategy for the energy storage device, the power swapping service level of the swapping station is guaranteed.

[0069] Preferably, enabling the power grid to charge the power battery and / or the energy storage device to charge the power battery to meet the power consumption demand corresponding to the first power demand further includes: enabling the power grid and / or the energy storage device to charge the power battery to meet the power consumption demand corresponding to the first power demand according to the power trading cost of the power grid.

[0070] Preferably, charging the energy storage device from the power grid and / or the on-site built energy storage system to the energy storage device to meet the power consumption demand corresponding to the second power demand further includes: charging the energy storage device from the power grid and / or the on-site built energy storage system to the energy storage device to meet the power consumption demand corresponding to the second power demand according to the power trading cost of the power grid. For example, if the on-site built energy storage system is preferred to charge the energy storage device, during the valley price period, the power grid can be used to charge the energy storage device to reduce the power exchange cost. Assuming that only building the energy storage system can meet the charging requirements of the energy storage device, the dependence on the power grid can be reduced at the energy storage level of the energy storage battery.

[0071] In the case where the power supply amount supplied by the power supply source cannot meet the power demand of the battery swapping station (in the future time period), it is necessary to adjust the preset power storage strategy. The situations that usually require adjusting the preset power storage strategy include:

[0072] 31) Neither the power battery nor the energy storage battery can meet the demand.

[0073] For this situation, for example, when calculating the power supply amount that can be provided, the cost elements of power trading such as electricity price and penalty are usually considered. Therefore, a method with more power grid intervention can be adopted to meet the power demand.

[0074] For example, in the case of charging priority (directly providing electric energy for the power battery), the current electricity price is used to charge the power battery. For projects with energy storage priority (providing electric energy for the energy storage device), the current electricity price can be used to charge the power battery. The charging requirements of both the power battery and the energy storage device can also be considered according to actual needs.

[0075] In a specific example, for a project with charging priority, the income brought by one battery swap is 50 yuan, and the income generated after energy storage is 40 yuan. The current choice is to charge the power battery at the current electricity price to preferentially meet the power demand corresponding to the power battery.

[0076] 32) The power battery cannot meet the demand, and the energy storage battery has already met the demand.

[0077] For this situation, the photovoltaic system can be used to charge the power battery to ensure the service level of the battery swapping station.

[0078] 33) The power battery cannot meet the demand, and the energy storage battery has already had an excess (the configured demand in the future time period is lower than the total current electricity amount of the energy storage battery).

[0079] For this situation, the method of feeding the power battery with the energy storage battery can be adopted.

[0080] Mainly refer to Figure 1, in a possible implementation, the present application provides a power swapping scheduling control method, mainly based on the energy supply system configured for the power swapping station (including optional multiple power input sources, such as in addition to the power grid, one or more power input sources for the power swapping station), to perform as reasonable as possible scheduling of electric energy for the power demand situation of the power swapping station. The power swapping scheduling control method mainly includes the following steps:

[0081] S110. Receive the power swapping request of the user;

[0082] S120. Determine whether to adjust the preset power charging and storage strategy according to the power swapping request;

[0083] If so, adjust the preset power charging and storage strategy in different ways according to different situations, specifically including:

[0084] S1301. In the case where the first power demand of the power battery and the second power demand of the energy storage battery cannot be satisfied, make the power grid charge the power battery and / or the energy storage device additionally, so as to at least partly satisfy the power consumption demand corresponding to the first power demand / second power demand. Exemplarily, fully satisfy the first power demand of the power battery with higher priority, and partly satisfy the second power demand of the energy storage device with lower priority to a certain extent.

[0085] S1302. In the case where the second power demand of the energy storage battery can be satisfied but the first power demand of the power battery cannot be satisfied, adjust "make the power grid charge the power battery and / or the energy storage device charge the power battery to satisfy the power consumption demand corresponding to the first power demand" to "make the power grid charge the power battery and / or the on-site energy storage system charge the power battery to satisfy the power consumption demand corresponding to the first power demand". In this way, through the timely replenishment of the on-site energy storage system, the power swapping cost of the power swapping station can be reduced as much as possible.

[0086] S1303. In the case where the second power demand of the energy storage battery is excessive but the first power demand of the power battery cannot be satisfied, adjust "make the power grid charge the power battery and / or the energy storage device charge the power battery to satisfy the power consumption demand corresponding to the first power demand" to "at least make the energy storage device charge the power battery to satisfy the power consumption demand corresponding to the first power demand". For example, in the case where only the energy storage device feeding power to the power battery can satisfy the first demand, there is no need for the power grid to participate in the power swapping scheduling mechanism for charging the power battery. In this way, the dependence on the power grid can be reduced. Especially in the peak price interval, the operation cost of the power swapping station can also be reduced.

[0087] For S1301 - S1303, perform the power charging and storage operation of the power swapping station based on the adjusted power charging and storage strategy, and provide power swapping services for this power swapping request.

[0088] S140. Operate according to a preset power charging and storage strategy, and provide battery swapping services for this battery swapping request.

[0089] It can be seen that in the preferred embodiment of the present application, through the configuration of the energy storage device, the effect of peak shaving and valley filling can be achieved to a certain extent, reducing the battery swapping service cost of the battery swapping station. By introducing the on-site energy storage, the dependence of the battery swapping station on the power grid is reduced. In places with high on-site energy storage power generation capacity such as Xinjiang Uygur Autonomous Region, it can even reach the level of reliable operation of the battery swapping station without using the power grid. By correspondingly adjusting the power charging and storage strategy for different situations, while ensuring the battery swapping service, the battery swapping service cost is reduced as much as possible and the battery swapping service level is improved.

[0090] It should be noted that although the above steps are described in a specific order in the above embodiments, those skilled in the art can understand that in order to achieve the effects of the present application, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously or in other orders, and some steps can also be added, replaced, or omitted. For example, “S1301. In the case where the first power demand of the power battery and the second power demand of the energy storage battery cannot be satisfied, make the power grid charge the power battery and / or the energy storage device additionally to at least a certain extent meet the power consumption demand corresponding to the first power demand / second power demand” can be replaced with “In the case where the first power demand of the power battery and the second power demand of the energy storage battery cannot be satisfied, make the power grid charge the power battery and / or the energy storage device additionally to meet the power consumption demand corresponding to the first power demand / second power demand” and so on.

[0091] It should be noted that although the battery swapping scheduling control method constituted by the above specific method is introduced as an example, those skilled in the art can understand that the present application should not be limited thereto. In fact, users can flexibly adjust relevant steps and parameters in the steps according to actual application scenarios and other situations. For example, in the case where both the power grid and the on-site energy storage charge the energy storage device, those skilled in the art can flexibly allocate the ratio between the two according to actual needs.

[0092] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principle of the present application, those skilled in the art can make equivalent changes or replacements to relevant technical features, and the technical solutions after these changes or replacements will fall within the protection scope of the present application.
