[0003] This application relates to the field of battery technology, and includes, but is not limited to, a charging reservation method and system. Background Technology

[0004] In recent years, the world has faced major challenges to sustainable development, such as energy shortages, climate change, and pollutant emissions. Therefore, countries have begun to pay widespread attention to the development of new energy vehicles, represented by electric vehicles. However, the development of electric vehicles is also affected by a series of constraints, among which range anxiety is considered one of the major obstacles to the widespread acceptance of pure electric vehicles. Compared to traditional automobiles, electric vehicles are more dependent on charging systems.

[0005] Users often face situations where they cannot reach their destination smoothly due to failure to charge in time, or their vehicles break down due to running out of power while traveling on urban roads. However, due to the low availability of charging stations and the large number of electric vehicles in the city, there is a shortage of charging stations, which are often occupied, making it impossible to charge the car in a timely manner. Summary of the Invention

[0006] To address the problems existing in the related technologies, this application provides a charging reservation method and system that can determine the target energy storage device based on the location of the vehicle to be charged, and make a timely reservation for the target energy storage device to replenish the vehicle's energy.

[0007] Firstly, this application provides a charging reservation method applied to a charging reservation system. The charging reservation system includes an in-vehicle infotainment system for a vehicle to be charged, multiple energy storage devices, and a cloud platform connected to the multiple energy storage devices. The charging reservation method includes: in response to a charging request, the in-vehicle infotainment system acquires at least two energy storage devices that meet the charging conditions and the power supply status of each energy storage device; the at least two energy storage devices are determined by the cloud platform from among the multiple energy storage devices based on the current location of the vehicle to be charged; the power supply status includes the current reservation status and power supply type of each energy storage device, and the power supply type includes supercharging, fast charging, and slow charging, with different power supply types affecting... The selection priorities of the energy storage devices to be powered differ; the vehicle-mounted system determines the power supply priority of each energy storage device based on its selection priority and occupancy status; the occupancy status is determined based on the current reservation status of each energy storage device; the vehicle-mounted system determines the target energy storage device from at least two devices based on the power supply priority and the driving information of the vehicle to be charged to each energy storage device, and sends charging reservation information to the target energy storage device; the target energy storage device responds to the charging reservation information by updating its current reservation status to realize the charging reservation of the vehicle to be charged.

[0008] In the above embodiments, the target energy storage device for charging the vehicle is determined by the selection priority, occupancy status, and vehicle driving information of each energy storage device that meets the charging conditions. The target energy storage device is then reserved. This not only ensures that the target energy storage device for charging the vehicle meets the needs of the vehicle waiting to be charged, but also avoids the vehicle being occupied by other vehicles while driving to the target energy storage device. This improves the charging success rate of the vehicle waiting to be charged, reduces the time spent driving to find an available charging station, and improves the charging efficiency of the vehicle waiting to be charged.

[0009] In some embodiments, the power supply status also includes the power supply location of each energy storage device to be powered; the vehicle system determines the target energy storage device among at least two energy storage devices to be powered based on the power supply priority and the driving information of the vehicle to be charged traveling to each energy storage device to be powered, including: determining the road condition information and travel time of the power supply path of the vehicle to be charged traveling to each energy storage device to be powered based on the current location of the vehicle to be charged and the power supply location of each energy storage device to be powered; and determining the target energy storage device among at least two energy storage devices to be powered by combining the power supply priority of each energy storage device to be powered, the travel time of the vehicle to be charged traveling to each energy storage device to be powered, and the road condition information of each power supply path.

[0010] In the above embodiments, based on the vehicle's drivable time, the driving path to each power supply and energy storage device, and the road conditions of each driving path, the power supply and energy storage device with the shortest time and the highest charging power is selected to charge the vehicle to be charged.

[0011] In some embodiments, occupancy status includes whether the energy storage device to be powered is currently occupied and the available charging time for each energy storage device when it is currently occupied; the selection priority of each energy storage device to be powered decreases in the order of supercharging, fast charging, and slow charging; the vehicle system determines the power supply priority of each energy storage device based on its selection priority and occupancy status, including: in response to the presence of a supercharging energy storage device among at least two energy storage devices to be powered, and the supercharging energy storage device is currently not occupied, determining the power supply priority of the supercharging energy storage device as level one; in response to the presence of a supercharging energy storage device among at least two energy storage devices to be powered, and the supercharging energy storage device is currently occupied, determining the travel time of the vehicle to be charged to the supercharging energy storage device based on its power supply location; in response to the travel time being greater than the available charging time, determining the power supply priority of the supercharging energy storage device as level one.

[0012] In the above embodiments, not only unoccupied charging piles are considered, but also the vehicle's driving time and the end time of occupied charging piles are taken into account, enabling more supercharging power supply energy storage devices to be charged, thus improving charging efficiency. In some embodiments, the method further includes: in response to the absence of a supercharging power supply energy storage device among at least two energy storage devices to be powered, determining the power supply priority of the currently unoccupied fast charging power supply energy storage device as level two, and determining the power supply priority of the currently unoccupied slow charging power supply energy storage device as level three.

[0013] In the above embodiments, based on the power supply type of the energy storage device, a supercharging power supply energy storage device is preferentially selected for the vehicle to be charged. However, when a supercharging power supply energy storage device is not available, a faster power supply energy storage device is provided to the vehicle based on the power supply type to improve charging efficiency.

[0014] In some embodiments, determining a target energy storage device among at least two energy storage devices to be powered, by combining the power supply priority of each energy storage device to be powered, the travel time of the vehicle to be charged to each energy storage device to be powered, and the road condition information of each power supply path, includes: in response to the existence of at least two energy storage devices to be powered with a power supply priority of level one among the at least two energy storage devices to be powered, comparing the drivable time of the vehicle to be charged with the travel time of the vehicle to be charged to the energy storage device to be powered with a power supply priority of level one, and obtaining a comparison result; in response to the comparison result indicating that there are at least two energy storage devices to be powered with a power supply priority of level one with a travel time less than the drivable time, determining the energy storage device to be powered with a power supply priority of level one with the shortest travel time as the target energy storage device, in combination with the road condition information; in response to the existence of one energy storage device to be powered with a power supply priority of level one among the at least two energy storage devices to be powered, and the travel time of the vehicle to be charged to the energy storage device to be powered with a power supply priority of level one with a power supply priority of level one being less than the drivable time, determining the energy storage device to be powered with a power supply priority of level one as the target energy storage device.

[0015] In the above embodiments, based on the vehicle's drivable time, the driving path to each power supply and energy storage device, and the road conditions of each driving path, the power supply and energy storage device with the shortest time and the highest charging power is selected to charge the vehicle to be charged.

[0016] In some embodiments, in response to the existence of a first-level energy storage device among at least two energy storage devices to be powered, and the travel time of the vehicle to be charged to the first-level energy storage device being powered is greater than the available travel time, it is determined whether there is a second-level energy storage device among the at least two energy storage devices to be powered; in response to the existence of a second-level energy storage device among the at least two energy storage devices to be powered, a target energy storage device is determined among the energy storage devices with a second-level power supply priority based on the road condition information and travel time of the power supply path of the vehicle to be charged to the second-level energy storage device.

[0017] In the above embodiments, based on the vehicle's drivable time, the driving path to each power supply and energy storage device, and the road conditions of each driving path, the power supply and energy storage device with the shortest time and the highest charging power is selected to charge the vehicle to be charged.

[0018] In some embodiments, the charging reservation method further includes: the vehicle system sending a data request to the cloud platform; the data request includes the current location and remaining mileage of the vehicle to be charged; the remaining mileage is determined by the battery management system of the vehicle to be charged; in response to the data request, the cloud platform identifies at least two energy storage devices within a preset range from the current location as energy storage devices to be supplied with power from among multiple energy storage devices; the preset range is less than the remaining mileage.

[0019] In the above embodiments, all energy storage transposition is integrated into the cloud platform, and the cloud platform interacts with the vehicle to be charged. This eliminates the need for the vehicle to check the status of each energy storage device to make a selection, thereby improving charging efficiency.

[0020] In some embodiments, the energy storage device includes an energy storage module, and the charging reservation information includes the reservation time and charging duration of the vehicle to be charged; the method further includes: the target energy storage device charging the energy storage module in response to the charging reservation information; correspondingly, updating the current reservation status of the target energy storage device includes: updating the reservation status of the corresponding time period in the current reservation status based on the reservation time and charging duration to obtain the updated current reservation status.

[0021] In the above embodiments, after the target energy storage device is reserved, it changes its current reservation status to avoid being occupied by other vehicles while the vehicle is traveling to the target energy storage device, thereby improving the charging success rate of the vehicle waiting to be charged.

[0022] In some embodiments, the method further includes: in response to a situation where the vehicle has made more than a preset number of charging reservations for the target energy storage device but has not charged it, the cloud platform receives the vehicle's data request again after a preset time period starting from the date the vehicle has not charged for more than the preset number of times, and provides the vehicle with at least two energy storage devices to be powered based on the vehicle's current location.

[0023] In the above embodiments, restrictions were placed on users' charging reservation behavior to avoid resource waste.

[0024] Secondly, embodiments of this application provide a charging reservation system, comprising: a vehicle-mounted system of a vehicle to be charged, configured to, in response to a charging request, acquire at least two energy storage devices that meet the charging conditions and the power supply status of each energy storage device; the power supply status includes the current reservation status and power supply type of each energy storage device, with different selection priorities for different power supply types; a cloud platform, configured to, based on the current location of the vehicle to be charged, determine at least two energy storage devices to be charged from among multiple energy storage devices connected to the cloud platform; the vehicle-mounted system, configured to, based on the selection priority and occupancy status of each energy storage device, determine the power supply priority of each energy storage device; wherein, the occupancy status is determined based on the current reservation status of each energy storage device; the vehicle-mounted system is further configured to, based on the power supply priority and driving information of the vehicle to be charged traveling to each energy storage device, determine a target energy storage device from the at least two energy storage devices to be charged, and send charging reservation information to the target energy storage device; and the target energy storage device, configured to, in response to the charging reservation information, update the current reservation status corresponding to the target energy storage device to realize the charging reservation of the vehicle to be charged.

[0025] In the above embodiments, the target energy storage device for charging the vehicle is determined by the selection priority, occupancy status, and vehicle driving information of each energy storage device that meets the charging conditions. The target energy storage device is then reserved. This not only ensures that the target energy storage device for charging the vehicle meets the needs of the vehicle waiting to be charged, but also avoids the vehicle being occupied by other vehicles while driving to the target energy storage device. This improves the charging success rate of the vehicle waiting to be charged, reduces the time spent driving to find an available charging station, and improves the charging efficiency of the vehicle waiting to be charged.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of this application pertain. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit the application.

[0035] Currently, new energy batteries are increasingly widely used in daily life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing. In this application embodiment, the battery involved can be a battery cell, also known as a battery unit. A battery cell refers to a basic unit capable of converting chemical energy into electrical energy, which can be used to manufacture battery modules or battery packs to supply power to electrical devices. A battery cell can be a rechargeable battery, which refers to a battery cell that can be recharged after discharge to activate the active materials and continue to be used. Battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc., and this application embodiment is not limited to these.

[0036] In this embodiment, the battery cell is the core component of the battery pack. A battery pack typically contains multiple battery cells, which are combined to provide the required energy capacity and voltage. The components of a battery pack include: individual battery cells, a battery management system (BMS), a casing, wiring harnesses, connectors, and interfaces. These components work together to combine the battery cells into a fully functional battery pack for various applications. For example, the battery pack can be used in electric vehicles, energy storage systems, portable electronic devices, solar power systems, wind power systems, emergency backup power supplies, power tools, or electric bicycles, etc. This embodiment does not impose any limitations on this; the specific choice can be made according to the actual application scenario.

[0037] In this application embodiment, the term "battery cell" can refer to any shape, such as a square cell or a round cell. Furthermore, "battery cell" typically refers to a battery cell, which is one of the basic units constituting a battery. The battery cell is the core component of a battery, responsible for storing and releasing electrical energy. A battery cell can be a lithium-ion battery cell (Li-ion Cell), a lithium-polymer battery cell (Li-polymer Cell), a nickel-metal hydride battery cell (NiMH Cell), etc. This application embodiment does not limit the type of battery cell; the specific type can be selected according to the actual application scenario.

[0038] It should be noted that the battery pack can use different types of battery cells, such as lithium-ion batteries, nickel-metal hydride batteries, lithium polymer batteries, etc., depending on the specific application requirements and performance specifications.

[0039] In this embodiment, the battery may also be a single physical module comprising one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, parallel, or mixed via a busbar.

[0040] Currently, when users need to charge their vehicles while driving, they typically use map software to find charging stations along their route. However, it's uncertain whether the charging station will be occupied by other vehicles while the vehicle is en route, causing continuous energy consumption and potentially leading to a low battery. Therefore, finding available charging stations and being able to reach them within the vehicle's remaining range to charge promptly is a pressing issue that needs to be addressed.

[0041] To alleviate the problems with the relevant technologies, the applicant discovered that energy storage devices capable of supplying power to the vehicle can be pre-determined based on the location of the vehicle to be charged. Then, based on the reservation status of each energy storage device and the driving information of the vehicle to be charged to each energy storage device, the target energy storage device that will ultimately supply power to the vehicle to be charged can be determined and reserved. This avoids the vehicle being occupied by other vehicles while it is driving to the target energy storage device, improves the charging success rate of the vehicle to be charged, and reduces the time spent driving to find an available charging station.

[0042] Based on the above considerations, after in-depth research, the applicant found that after receiving a charging request, the vehicle's infotainment system can send the vehicle's current location to the cloud platform. The cloud platform then determines at least two energy storage devices that meet the charging conditions and their power supply status based on the vehicle's current location, and sends this information to the vehicle's infotainment system. Based on the power supply status of each energy storage device and the vehicle's driving information, the vehicle's infotainment system determines the target energy storage device for charging the vehicle and makes a reservation for the target energy storage device.

[0043] In this way, the embodiments of this application determine the target energy storage device for charging the vehicle by the power supply status of each energy storage device that meets the charging conditions and the vehicle's driving information, and make a reservation for the target energy storage device. This not only ensures that the target energy storage device for charging the vehicle meets the needs of the vehicle to be charged, but also avoids the vehicle being occupied by other vehicles while driving to the target energy storage device, thereby improving the charging success rate of the vehicle to be charged, reducing the time spent driving to find an available charging station, and improving the charging efficiency of the vehicle to be charged.

[0044] The charging reservation method disclosed in this application can be used, but is not limited to, in electrical equipment such as vehicles, electric bicycles, and electric wheelchairs. Charging reservations can be made using the charging reservation method disclosed in this application.

[0045] This application provides a charging reservation method. The executing entity can be a charging reservation system. Figure 1 is a schematic diagram of the charging reservation system provided in this application. As shown in Figure 1, the charging reservation system 10 includes a vehicle-mounted system 101 of the vehicle to be charged, multiple energy storage devices (the first energy storage device 102-1 to the nth energy storage device 102-n in the figure) and a cloud platform 103 connected to the multiple energy storage devices through cloud services.

[0046] Here, the vehicle to be charged can refer to any pure electric or hybrid vehicle powered by a battery, and the vehicle infotainment system 101 refers to the intelligent in-vehicle system of the vehicle to be charged. It may include functions such as a central control screen, audio system, navigation system, and vehicle control, and is an important component of the electric vehicle. The vehicle infotainment system communicates with the cloud platform 103 and performs calculations through various sensors, controllers, and communication modules.

[0047] The first energy storage device 102-1 to the nth energy storage device 102-n can be an integrated energy storage and charging unit. An integrated energy storage and charging unit refers to a device that integrates energy storage equipment and charging facilities, and may include energy storage devices (such as batteries) and charging facilities (such as charging piles) to realize the function of storing and releasing electrical energy. An integrated energy storage and charging unit can store electrical energy when the grid load is low or the electricity price is cheap, and then release it to charge electric vehicles or other devices when needed, which helps to balance the grid load, reduce charging costs, and improve energy utilization efficiency.

[0048] Here, the cloud platform 103 can be implemented as a terminal or as a server. In one implementation, the cloud platform provided in this embodiment can be implemented as any terminal with data processing capabilities, such as a laptop, tablet, desktop computer, mobile device, smart robot, smart home appliance, and smart vehicle device. In another implementation, the cloud platform provided in this embodiment can also be implemented as a server, wherein the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms. The terminal and the server can be connected directly or indirectly through wired or wireless communication, which is not limited in this embodiment.

[0049] It's important to note that the cloud platform 103 can be implemented through cloud technology or cloud services. Cloud technology refers to a hosting technology that unifies hardware, software, and network resources within a wide area network (WAN) or local area network (LAN) to achieve data computation, storage, processing, and sharing. Cloud technology is a general term encompassing network technology, information technology, integration technology, management platform technology, and application technology applied to the cloud computing business model. It can form resource pools, providing flexible and convenient on-demand access. Cloud computing technology will become a crucial support. Backend services of technical network systems require substantial computing and storage resources, such as video websites, image websites, and many portal websites. With the rapid development and application of the internet industry, every item may have its own identification mark in the future, requiring transmission to backend systems for logical processing. Data at different levels will be processed separately, and various industry data will require robust system support, which can only be achieved through cloud computing.

[0050] In this embodiment of the application, the vehicle-mounted system 101 can be connected to the cloud platform 103 via a network, and the cloud platform 103 can be connected to multiple energy storage devices via a network. The network can be a wide area network or a local area network, or a combination of the two.

[0051] When the charging reservation system 10 provided in this application is running, the vehicle-mounted system 101 of the vehicle to be charged responds to the charging request and obtains at least two energy storage devices that meet the charging conditions and the power supply status of each energy storage device provided by the cloud platform 103. The power supply status includes the current reservation status and power supply type of each energy storage device, and the selection priority of the energy storage devices corresponding to different power supply types is different. Based on the current location of the vehicle to be charged, the cloud platform 103 determines at least two energy storage devices (such as the first energy storage device 102-1 to the nth energy storage device 102-n) connected to the cloud platform 103 to provide power to the vehicles. The vehicle-mounted unit 101 is also used to determine the power supply priority of each energy storage device based on the selection priority and occupancy status of each energy storage device to be powered; wherein, the occupancy status is determined based on the current reservation status of each energy storage device to be powered; the vehicle-mounted unit is also used to determine the target energy storage device among at least two energy storage devices to be powered based on the power supply priority and the driving information of the vehicle to be charged traveling to each energy storage device to be powered, and send charging reservation information to the target energy storage device; the target energy storage device is used to update the current reservation status corresponding to the target energy storage device in response to the charging reservation information, so as to realize the charging reservation of the vehicle to be charged.

[0052] In this way, the embodiments of this application determine the target energy storage device for charging the vehicle by selecting the priority and occupancy status of each energy storage device that meets the charging conditions and the vehicle's driving information, and make a reservation for the target energy storage device. This not only ensures that the target energy storage device for charging the vehicle meets the needs of the vehicle waiting to be charged, but also avoids the vehicle being occupied by other vehicles while driving to the target energy storage device, thereby improving the charging success rate of the vehicle waiting to be charged, reducing the time spent driving to find an empty charging station, and improving the charging efficiency of the vehicle waiting to be charged.

[0053] The following will describe an exemplary application of the cloud platform as a server, and the technical solution of this application will be described in detail with reference to the accompanying drawings.

[0054] Figure 2 is an optional flowchart of the charging reservation method provided in this application embodiment. As shown in Figure 2, the charging reservation method provided in this application embodiment can be implemented through steps S201 to S204:

[0055] Step S201: In response to the charging request, the vehicle system obtains at least two energy storage devices that meet the charging conditions and the power supply status of each energy storage device. The at least two energy storage devices are determined by the cloud platform from multiple energy storage devices based on the current location of the vehicle to be charged. The power supply status includes the current reservation status and power supply type of each energy storage device. The power supply type includes supercharging, fast charging and slow charging. The selection priority of the energy storage devices corresponding to different power supply types is different.

[0056] In some embodiments, a charging request can be a command input or selected by the user on the vehicle's central control screen, including but not limited to selection, confirmation, page turning, and scrolling operations on the central control screen. For example, a user can select the scheduled charging component on the vehicle's central control screen to issue a charging request. In this case, the charging request is issued by the user driving the vehicle to be charged at any time and is unrelated to the remaining battery power of the vehicle.

[0057] In some embodiments, the charging request may also be issued by the battery management system (BMS) of the vehicle to be charged. When the remaining charge (SOC) of the battery is less than a preset threshold, such as SOC less than 20%, or when the BMS detects a battery abnormality (such as rapid power loss), it sends a charging request to the vehicle's infotainment system to charge the battery and prevent the vehicle from running out of power and breaking down.

[0058] In some embodiments, in response to a charging request, the vehicle's infotainment system can send a data request to the cloud platform containing the vehicle's State of Charge (SOC) and current location. This data request requests the cloud platform to determine which energy storage devices can charge the vehicle based on its SOC and current location. Here, the cloud platform is connected to all energy storage devices and can obtain the real-time power supply status of each device, such as whether it is currently supplying power, the nearest available time if it is, and the power output of each device (e.g., whether it is a supercharging energy storage device). Based on the vehicle's SOC, the cloud platform can determine the remaining mileage of the vehicle to obtain its maximum driving range. Then, based on the vehicle's current location, it determines a range within which the vehicle can be supplied with power. The cloud platform can send the power supply status of all energy storage devices within this range to the vehicle's infotainment system, which then selects the appropriate energy storage device based on the vehicle's condition.

[0059] Here, the energy storage devices awaiting power supply refer to all energy storage devices within this range, regardless of whether they are currently occupied. The current reservation status of the energy storage device awaiting power supply can refer to whether the energy storage device is currently occupied and the available time for recharging when it is currently occupied. The available time for recharging refers to the most recent available time for the energy storage device. For example, if the current time is 13:00, and the available time for recharging when the energy storage device is currently occupied is 13:30, then the energy storage device can also supply power to the vehicle waiting to be charged.

[0060] In some embodiments, the charging condition may be that the vehicle is within a preset distance from the current location of the vehicle to be charged. The preset distance is determined based on the SOC of the vehicle to be charged. After the cloud platform determines at least two energy storage devices that meet the charging conditions and the power supply status of each energy storage device, it sends the information to the vehicle's infotainment system.

[0061] In some embodiments, the power supply type of the energy storage device to be powered refers to whether the energy storage device to be powered is an overcharge energy storage device, a fast charge energy storage device, or a slow charge energy storage device, and the charging power of energy storage devices with different power supply types is different.

[0062] The energy storage device in this embodiment can be an integrated energy storage and charging unit. This integrated unit can be equipped with multiple charging piles, each capable of supercharging, fast charging, and slow charging. Multiple charging piles can be used simultaneously. The ability of the energy storage device to achieve supercharging, fast charging, and slow charging depends on the remaining battery capacity, output voltage, current, power, and other conditions of the integrated unit's battery. Therefore, this embodiment preferentially selects an energy storage device capable of providing supercharging.

[0063] Here, the energy storage device can also be a charging station with a longer deployment time, which can only provide one of the functions of supercharging, fast charging, or slow charging. For example, the power of a supercharging power supply energy storage device is 120 kilowatts (kW) to 250 kW, while the power of a fast charging power supply energy storage device is about 75 kW. In order to make car charging faster and more convenient, supercharging power supply energy storage devices should be given priority when selecting target energy storage devices, so that vehicles waiting to be charged can quickly replenish their energy.

[0064] Therefore, after obtaining the power supply type of each energy storage device to be powered, the selection priority of each energy storage device to be powered can be determined based on the power supply type of each energy storage device to be powered. For example, the selection priority of supercharging energy storage device, fast charging energy storage device and slow charging energy storage device decreases in that order.

[0065] Step S202: The vehicle system determines the power supply priority of each energy storage device based on the selection priority and occupancy status of each energy storage device to be powered; wherein, the occupancy status is determined based on the current reservation status of each energy storage device to be powered.

[0066] In some embodiments, the current reservation status can characterize the charging occupancy status of the corresponding energy storage device. The occupancy status includes whether the energy storage device to be powered is currently occupied and the available charging reservation time for each energy storage device when it is currently occupied.

[0067] Here, power supply priority refers to the order in which the target energy storage device is determined among at least two devices. That is, the device with the highest power supply priority is considered first; if the device with the highest power supply priority cannot be selected as the target energy storage device, then the next highest priority device is considered.

[0068] The power supply priority is determined based on the occupancy status and selection priority of each energy storage device waiting to be powered. For example, based on the selection priority, it is determined whether there is an overchargeable energy storage device among at least two energy storage devices waiting to be powered. Then, based on the occupancy status of the overchargeable energy storage device, further judgment is made. For example, the power supply priority of an unoccupied overchargeable energy storage device is higher than that of an occupied overchargeable energy storage device, thereby determining the power supply priority of each energy storage device waiting to be powered.

[0069] In some embodiments, the power supply priority of each energy storage device can be determined by combining the electricity cost of charging the vehicle at each energy storage device. Since the distance to each energy storage device is different, the areas where each energy storage device is located are different. For example, some are energy storage devices in commercial areas, and some are energy storage devices in residential areas. The arrival time is also different, resulting in different charging prices. Therefore, the power supply priority of each energy storage device can also be determined by combining the electricity cost. For example, among the supercharging energy storage devices that are in an idle state, the energy storage device with the lower electricity cost has a higher power supply priority.

[0070] Step S203: Based on the power supply priority and the driving information of the vehicle to be charged traveling to each energy storage device to be powered, the vehicle-mounted unit determines the target energy storage device among at least two energy storage devices to be powered and sends charging reservation information to the target energy storage device.

[0071] In some embodiments, the driving information of the vehicle to be charged to each energy storage device may refer to the optimal driving route of the vehicle to each energy storage device, the driving time based on the optimal driving route, the road condition information of the optimal driving route, and the status of the energy storage devices along the optimal driving route (for example, there are multiple energy storage transpositions along the way, so that in the event of an extreme situation (such as a sudden battery loss) during the driving, the vehicle can drive to the nearest energy storage device along the way to wait for charging).

[0072] In some embodiments, after determining the power supply priority of each energy storage device to be powered, when there are multiple unoccupied supercharging energy storage devices (i.e., the energy storage device with the highest power supply priority) among at least two energy storage devices to be powered, the supercharging energy storage device with the shortest driving time can be identified as the target energy storage device.

[0073] Here, the priority sequence of multiple unoccupied energy storage devices can also be determined based on the travel time, with the one with the shortest travel time having the highest priority. Then, the target energy storage device can be determined based on the road conditions of each travel route, for example, if the road conditions are currently free of traffic jams or road repairs.

[0074] In some embodiments, after receiving information from at least two power storage devices, the vehicle's infotainment system can display these devices on a map on the central control screen for the user to view. The user can then select an unoccupied power storage device near their destination as the target device and send a charging reservation message to that device. The user can also tap the central control screen to view the power status of the power storage devices and select the target device.

[0075] In some embodiments, after a target energy storage device is identified, a charging reservation information is sent to the target energy storage device to reserve the target energy storage device and prevent other vehicles from using the target energy storage device for charging before the vehicle waiting to be charged arrives at the target energy storage device.

[0076] In some embodiments, the charging reservation information may include at least the charging reservation time for the vehicle to be charged, for example, the charging reservation information is that charging will start at 14:00 and the charging time will be 1 hour.

[0077] Here, if the target energy storage device is currently not occupied, the charging reservation time in the charging reservation information can be the current moment, that is, the reservation starts from the current moment; if the target energy storage device is currently occupied, the charging reservation time in the charging reservation information can be the time when the vehicle to be charged is expected to travel to the target energy storage device, or the earliest time when the target energy storage device can be reserved.

[0078] Step S204: The target energy storage device responds to the charging reservation information by updating the reservation information corresponding to the target energy storage device, so as to realize the charging reservation of the vehicle to be charged.

[0079] In this embodiment of the application, after receiving the charging reservation information, the target energy storage device modifies the current reservation status of the target energy storage device based on the charging reservation time and reservation duration in the charging reservation information. For example, the time period from 14:00 to 15:00 is updated to be reserved and displayed on the display interface of the target energy storage device.

[0080] This application embodiment determines the target energy storage device for charging the vehicle by using the power supply status of each energy storage device that meets the charging conditions and the vehicle's driving information, and makes a reservation for the target energy storage device. This not only ensures that the target energy storage device for charging the vehicle meets the needs of the vehicle waiting to be charged, but also avoids the vehicle being occupied by other vehicles while driving to the target energy storage device, thereby improving the charging success rate of the vehicle waiting to be charged, reducing the time spent driving to find an available charging station, and improving the charging efficiency of the vehicle waiting to be charged.

[0081] In some embodiments, the occupancy status includes whether the energy storage device to be powered is currently occupied and the available charging time for each energy storage device when it is currently occupied. The selection priority of each energy storage device to be powered decreases in the order of supercharging, fast charging, and slow charging. Step S202 can be implemented through steps S3031 to S3034:

[0082] Step S3031: In response to the existence of an overchargeable energy storage device among at least two energy storage devices to be powered, and the overchargeable energy storage device is currently not occupied, the power supply priority of the overchargeable energy storage device is determined to be Level 1.

[0083] In some embodiments, if an overchargeable energy storage device is present among at least two energy storage devices awaiting power supply, and that overchargeable energy storage device is currently unoccupied, then its power supply priority can be directly determined as Level 1. When determining the target energy storage device, priority is given to judging the energy storage device awaiting power supply with a power supply priority of Level 1.

[0084] Step S3032: In response to the presence of an overchargeable energy storage device among at least two energy storage devices to be powered, and the overchargeable energy storage device is currently occupied, determine the time when the vehicle to be charged travels to the overchargeable energy storage device based on the power supply location of the overchargeable energy storage device.

[0085] In some embodiments, if there is an overchargeable energy storage device among at least two energy storage devices to be powered, but the overchargeable energy storage device is currently occupied, that is, a vehicle is currently charging the overchargeable energy storage device, then the driving time of the vehicle to be charged to the overchargeable energy storage device can be determined according to the power supply location of the overchargeable energy storage device, that is, the time when the vehicle to be charged arrives at the overchargeable energy storage device can be determined, for example, 13:47.

[0086] In some embodiments, determining the travel time of the vehicle to be charged to the supercharging power storage device can be achieved by the vehicle's infotainment system determining the vehicle's travel path based on the power supply location of the supercharging power storage device and the current location of the vehicle, and estimating the travel path and road conditions. Here, the vehicle's infotainment system can obtain multiple travel paths.

[0087] Step S3033: In response to the driving time being greater than the rechargeable reservation time, the power supply priority of the supercharging power storage device is determined to be Level 1.

[0088] Here, the available charging time slot refers to the nearest available charging time slot for the supercharging power supply and energy storage device. For example, if the current time is 12:58, the supercharging power supply and energy storage device is currently supplying power to other vehicles, but is expected to end at 13:36, and the vehicle waiting to be charged can drive to the supercharging power supply and energy storage device at 13:47, that is, the driving time is greater than the available charging time slot. At this time, the supercharging power supply and energy storage device is no longer occupied. In this case, the power supply priority of the supercharging power supply and energy storage device can be determined as level one.

[0089] In some embodiments, if the driving time is less than the scheduled charging time, the supercharging power storage device is determined to be an energy storage device that cannot provide power to the vehicle to be charged.

[0090] In this embodiment, not only unoccupied charging piles are considered, but also the vehicle's driving time and the end time of occupied charging piles are taken into account, which enables more supercharging power supply and energy storage devices to be charged, thus improving charging efficiency.

[0091] Step S3034: In response to the absence of an overcharge power supply energy storage device among at least two power supply energy storage devices, the power supply priority of the currently unoccupied fast charge power supply energy storage device is determined to be Level 2, and the power supply priority of the currently unoccupied slow charge power supply energy storage device is determined to be Level 3.

[0092] In some embodiments, if none of the at least two energy storage devices to be powered are supercharging energy storage devices, then fast charging energy storage devices are given priority in supplying power to the vehicles to be charged, and the power supply priority of the currently unoccupied fast charging energy storage device is determined to be level two. Alternatively, if the fast charging energy storage device is already occupied, but the time it takes for the vehicle to reach the fast charging energy storage device is longer than the device's scheduled charging time, then the power supply priority of that fast charging energy storage device is also determined to be level two.

[0093] Alternatively, the power supply priority of currently unoccupied slow-charging energy storage devices can be set to level three. Or, if a vehicle that is already occupied is driven to a slow-charging energy storage device at a time when the time it takes for the vehicle to reach the slow-charging energy storage device is longer than the scheduled charging time for the fast-charging energy storage device, the power supply priority of that slow-charging energy storage device can also be set to level three.

[0094] In some embodiments, after determining the power supply priority of the energy storage device, when determining the target energy storage device, in addition to the power supply priority, the battery type of the vehicle to be charged can also be matched with the power supply type of the energy storage device to obtain the target energy storage device.

[0095] Based on the power supply type of the energy storage device, this application embodiment prioritizes selecting a supercharging power supply energy storage device for the vehicle to be charged. However, when a supercharging power supply energy storage device is not available, a faster power supply energy storage device is provided to the vehicle based on the power supply type to improve charging efficiency.

[0096] In some embodiments, the power supply status also includes the power supply location of each energy storage device to be powered. Based on the current reservation status, power supply location, power supply priority, and driving information of the vehicle to be charged traveling to each energy storage device to be powered, a target energy storage device can be determined from at least two energy storage devices to be powered. Figure 3 is an optional flowchart of the charging reservation method provided in this application embodiment. As shown in Figure 3, step S203 can be implemented through steps S301 and S302:

[0097] Step S301: Based on the current location of the vehicle to be charged and the power supply location of each energy storage device to be powered, determine the road condition information and travel time of the path from the vehicle to the energy storage device to be powered.

[0098] Here, after obtaining the power supply location of each energy storage device to be powered, the driving path from the current location to each energy storage device can be determined based on the current location of the vehicle to be charged. The driving path can be realized based on the map of the vehicle.

[0099] After determining the driving route, the driving time of the vehicle to be charged to each energy storage device can be estimated based on the vehicle's speed, thus obtaining the arrival time of each energy storage device.

[0100] In some embodiments, the vehicle system also receives traffic information in real time, determines the road conditions of each driving route (e.g., whether there is traffic congestion), and updates the travel time and arrival time of each energy storage device to be powered in real time based on the road conditions.

[0101] Step S302: Based on the power supply priority of each energy storage device to be powered, the travel time of the vehicle to be charged to each energy storage device to be powered, and the road condition information of each power supply path, determine the target energy storage device among at least two energy storage devices to be powered.

[0102] In some embodiments, after determining the priority level of each energy storage device to be powered and the travel time and road conditions to each energy storage device, the target energy storage device is considered in combination with this information. For example, based on the power supply priority, it can be first determined whether there is a device in the first-level energy storage device that can supply power to the vehicle to be charged based on the travel time; if not, the second-level energy storage device is considered.

[0103] In some embodiments, step S302 can be implemented by steps S3021 to S3025:

[0104] Step S3021: In response to the presence of at least two energy storage devices with a power supply priority of level 1 among the at least two energy storage devices to be powered, the driving time of the vehicle to be charged is compared with the driving time of the vehicle to be charged to reach the energy storage device with a power supply priority of level 1, and a comparison result is obtained.

[0105] In some embodiments, the presence of an overchargeable power supply device is first determined based on the power supply priority. If there are at least two overchargeable power supply energy storage devices with a power supply priority of level one among at least two energy storage devices to be powered, that is, there are more than two overchargeable power supply energy storage devices that can be powered, then the driving time of the vehicle to be charged can be determined, that is, how long the vehicle can still drive and whether it can drive to the energy storage device.

[0106] Here, the drivable time can be obtained directly from the BMS by the vehicle's infotainment system, or it can be estimated by the vehicle's infotainment system based on the SOC of the vehicle to be charged and the vehicle's driving speed.

[0107] Here, the travel time for the vehicle to reach the energy storage device with the highest power supply priority can be obtained by first estimating the optimal travel path for each energy storage device and then using the vehicle's travel speed and the optimal travel path.

[0108] This application compares the driving time with the driving time of the vehicle to be charged to the energy storage device with the first-level power supply priority, in order to determine whether the vehicle's remaining power can reach each energy storage device.

[0109] Step S3022: In response to the comparison results indicating that there are at least two energy storage devices with a power supply priority of level 1 that have a travel time shorter than the available travel time, the energy storage device with the shortest travel time is identified as the target energy storage device, based on the road condition information.

[0110] Here, if the driving time of the vehicle to be charged is greater than that of the energy storage device with the highest power supply priority, that is, if the remaining power of the vehicle to be charged can drive to the energy storage device with the highest power supply priority, then based on the obtained road condition information, the driving time to the energy storage device with the highest power supply priority is updated, and the energy storage device with the shortest driving time is determined as the target energy storage device.

[0111] Step S3023: In response to the existence of a power supply priority level 1 among at least two power supply energy storage devices, and the driving time of the vehicle to be charged to the power supply priority level 1 power supply energy storage device is less than the driving time, the power supply priority level 1 power supply energy storage device is determined as the target energy storage device.

[0112] In some embodiments, if there is a power supply priority level 1 among at least two power supply energy storage devices, and the driving time of the vehicle to be charged to the power supply priority level 1 power supply energy storage device is less than the available driving time, it means that the remaining power of the vehicle to be charged can drive to the power supply priority level 1 power supply energy storage device. At this time, the power supply priority level 1 power supply energy storage device is determined as the target energy storage device.

[0113] Step S3024: In response to the existence of a power supply priority level 1 energy storage device among at least two power supply energy storage devices, and the driving time of the vehicle to be charged to the power supply priority level 1 energy storage device being greater than the driving time, determine whether there is a power supply priority level 2 energy storage device among the at least two power supply energy storage devices.

[0114] In some embodiments, if one of the at least two energy storage devices to be powered has a power supply priority of level one, and the driving time of the vehicle to be charged to the energy storage device with a power supply priority of level one is greater than the available driving time, it indicates that the remaining power of the vehicle to be charged is insufficient to reach the energy storage device with a power supply priority of level one. At this time, the vehicle to be charged cannot be charged by the supercharging energy storage device. Then, it is determined whether there is an energy storage device with a power supply priority of level two. If there is, the vehicle to be charged is powered by the fast charging energy storage device.

[0115] Step S3025: In response to the existence of a second-level energy storage device among at least two energy storage devices to be powered, the target energy storage device is determined among the second-level energy storage devices based on the road condition information and travel time of the power supply path of the vehicle to be charged to the energy storage device with a second-level power supply priority.

[0116] In this embodiment of the application, if there is a second-level power supply priority among at least two power supply energy storage devices, the number of fast charging power supply energy storage devices is determined. If there are multiple fast charging power supply energy storage devices, based on the aforementioned similar steps, one fast charging power supply energy storage device is determined to supply power to the vehicle to be charged through road condition information and driving time.

[0117] Based on the vehicle's drivable time, the travel path to each power supply and energy storage device, and the road conditions of each travel path, this application selects the energy storage device that can provide power, has the shortest time, and the highest charging power to charge the vehicle.

[0118] In some embodiments, the cloud platform is connected to all energy storage devices and is used to respond to data acquisition requests from vehicles to be charged, and to acquire information on energy storage devices within range that can supply power to the vehicles to be charged and the corresponding information of the energy storage devices. That is, at least two energy storage devices to be charged are determined by the cloud platform. Therefore, the charging reservation method provided in this application embodiment may further include steps S1 and S2:

[0119] Step S1: The vehicle's infotainment system sends a data request to the cloud platform. The data request includes the current location and remaining mileage of the vehicle to be charged. The remaining mileage is determined by the battery management system of the vehicle to be charged.

[0120] In some embodiments, the data request is used to request the cloud platform to find at least two energy storage devices capable of providing power near the vehicle to be charged, based on the vehicle's current location and remaining mileage.

[0121] Step S2: In response to the data request, the cloud platform identifies at least two energy storage devices within a preset range from the current location as energy storage devices to be supplied with power; the preset range is less than the remaining mileage.

[0122] In this embodiment of the application, after obtaining the remaining mileage of the vehicle to be charged, the cloud platform can determine the maximum range that the vehicle to be charged can travel based on the remaining mileage, i.e., the preset range, identify the energy storage devices within the preset range as energy storage devices that can supply power to the vehicle to be charged, and send the power supply status of at least two energy storage devices within the preset range to the vehicle to be charged.

[0123] In some embodiments, if there is only one energy storage device within a preset range, the energy storage device is sent to the vehicle to be charged, and the vehicle to be charged confirms whether to reserve a time slot for the energy storage device and drives the vehicle to the energy storage device to wait for charging.

[0124] In some embodiments, if there is no energy storage device within a preset range, the information that there is no energy storage device is sent to the vehicle to be charged, and the vehicle to be charged performs subsequent operations.

[0125] This application embodiment integrates all energy storage transposition into a cloud platform, and interacts with the vehicle to be charged through the cloud platform. The vehicle to be charged does not need to check the status of each energy storage device to make a selection, thus improving charging efficiency.

[0126] In some embodiments, the energy storage device includes an energy storage module and a control module. The energy storage module can refer to a battery to realize the functions of storing and releasing electrical energy. The energy storage module enables the storage of electrical energy when the grid load is low or the electricity price is cheap, and then releases it to charge electric vehicles or other devices when needed. Therefore, the charging reservation method provided in this application embodiment may further include the target energy storage device charging the energy storage module in response to charging reservation information; that is, the control module of the target energy storage device charging the energy storage module in response to the charging reservation information.

[0127] In some embodiments, the charging reservation information may include the reservation time and charging duration of the vehicle to be charged. Therefore, updating the current reservation status corresponding to the target energy storage device in step S204 includes updating the reservation status of the corresponding time period in the current reservation status based on the reservation time and charging duration to obtain the updated current reservation status.

[0128] In some embodiments, the charging reservation information may be that charging starts at 14:00 and lasts for 1 hour. The vehicle to be charged can send the charging reservation information directly to the target energy storage device, or it can send the charging reservation information to the target energy storage device via a cloud platform.

[0129] After receiving the charging reservation information, the target energy storage device modifies the current reservation status based on the charging reservation time and reservation duration in the charging reservation information. For example, the time period from 14:00 to 15:00 is updated to be reserved and displayed on the display interface of the target energy storage device.

[0130] In this embodiment, after the target energy storage device is reserved, it changes its current reservation status to avoid being occupied by other vehicles while the vehicle is traveling to the target energy storage device, thereby improving the charging success rate of the vehicle waiting to be charged.

[0131] In some embodiments, the energy storage device may further include sensors, a display interface, and a voice module. The charging reservation method provided in this application embodiment may further include step S11:

[0132] Step S11: The target energy storage device determines, based on sensors, that vehicles other than those waiting to be charged have entered the charging area of ​​the target energy storage device, displays the updated current reservation status on the display interface, and provides voice guidance to the vehicles based on the voice module.

[0133] Here, the sensor is used to detect whether a vehicle has entered the charging area corresponding to the target energy storage device. If a vehicle enters and is not a vehicle that was reserved for charging, the updated current reservation status can be displayed on the display interface (for example, displaying the text "Reserved"). The vehicle can also be given voice guidance based on the voice module, for example, prompting that the energy storage device has been reserved and indicating the location of the nearest energy storage device, guiding the vehicle to leave.

[0134] The target energy storage device in this embodiment of the application realizes interaction with the vehicle through a voice module, which avoids the target energy storage device being occupied by other vehicles before the vehicle to be charged arrives.

[0135] In some embodiments, to avoid resource waste and prevent users from making multiple reservations and failing to charge within the specified time, the cloud platform can restrict users who have made more than three successful reservations but failed to charge within the specified time. Therefore, the charging reservation method provided in this application embodiment may further include step S21:

[0136] Step S21: In response to the situation where the vehicle has made more than a preset number of charging reservations for the target energy storage device but has not charged, the cloud platform receives the vehicle's data request again after a preset time period starting from the time the vehicle has not charged for more than the preset number of times. Based on the vehicle's current location, the cloud platform provides the vehicle with at least two energy storage devices to be powered.

[0137] In this embodiment of the application, the preset number of times can be 3. If a vehicle makes an appointment for the energy storage device three times but fails to charge on time, the cloud platform can restrict the vehicle for a preset period of time (e.g., one month). For example, starting from the time the vehicle fails to charge more than 3 times, the cloud platform will no longer receive data requests from the vehicle for one month. During this month, the vehicle will not be able to obtain information about the energy storage device through the cloud platform and will not be able to quickly find a suitable power supply device.

[0138] This application embodiment restricts users' charging reservation behavior to avoid resource waste.

[0139] The charging reservation method provided in this application is based on a charging reservation system. The description of the system embodiment is similar to that of the method embodiment described above, and has similar beneficial effects. In some embodiments, the functions or modules included in the system provided in this disclosure can be used to execute the method described in the method embodiment above. For technical details not disclosed in the system embodiments of this application, please refer to the description of the method embodiments of this application for understanding.

[0140] The following will describe an exemplary application of the embodiments of this application in a real-world application scenario.

[0141] In view of the problem in related technologies that there are not enough charging positions for electric vehicles during operation and they are often occupied, this application provides a scheduled charging method based on an integrated energy storage and charging unit. Figure 4 is a flowchart of the scheduled charging method provided in this application. As shown in Figure 4, the scheduled charging method can be implemented through steps S401 to S410:

[0142] S401. Users can find and confirm the integrated charging and storage machine on map apps / mini-programs / mobile apps and activate the charging station reservation function.

[0143] In this embodiment of the application, when driving a vehicle, the user can find and confirm the integrated charging and storage unit on software such as map application (APP), mini program or mobile APP, and start the charging pile reservation function.

[0144] Here, map apps / mini-programs / mobile apps and other software communicate with the monitoring platform (i.e., cloud platform) via wireless communication, and the monitoring platform communicates with each integrated storage and charging unit through cloud services.

[0145] The integrated energy storage and charging unit here can be selected by the vehicle driver from multiple integrated energy storage and charging units that can provide power to the vehicle, based on the vehicle's current location, determined by the cloud platform.

[0146] Figure 5 is a schematic diagram of the architecture of the scheduled charging method provided in the embodiment of this application. As shown in Figure 5, the terminal 501 can be a mobile terminal or a vehicle-mounted system. The map APP, mini program or mobile APP on the mobile phone, or the vehicle-mounted system communicates with the monitoring platform 503 through the communication operator 502. The monitoring platform 503 communicates with each integrated charging and storage unit (e.g., the first integrated charging and storage unit 1 to the nth integrated charging and storage unit n) through the cloud service 504. The first integrated charging and storage unit 1 is composed of at least a first control unit 1-1 and a first wireless communication module 1-11. The first control unit 1-1 communicates with the cloud service 504 through the first wireless communication module 1-11, and the nth control unit n-1 communicates with the cloud service 504 through the nth wireless communication module n-11.

[0147] S402. Calculate map navigation time t using map apps / mini-programs / mobile apps and other software.

[0148] In this embodiment of the application, after finding an integrated charging and storage unit, the path from the vehicle to be charged to the integrated charging and storage unit can be determined based on the map, thereby determining the navigation time t.

[0149] S403. Is the navigation time t less than or equal to p?

[0150] In some embodiments, if the navigation time t is less than or equal to p, step S404 is executed to determine whether the current charging and storage unit is occupied; if the navigation time t is greater than p, step S405 is executed to prompt the user "Too far from the charging station, charging reservation unsuccessful!".

[0151] Here, p can be a user-defined time, such as 1 hour, or p can be the battery life of the battery to be recharged.

[0152] S404. Is the current integrated storage and charging unit currently in use?

[0153] In some embodiments, it is determined whether a vehicle is currently charging at the integrated charging and storage unit.

[0154] In some embodiments, if the current storage and charging unit is occupied, step S406 is executed; if the current storage and charging unit is not occupied, step S408 is executed.

[0155] S405: The user is prompted with the message "Too far from the charging station, charging reservation unsuccessful!"

[0156] S406. Is the remaining time e of the storage and charging integrated machine being occupied less than or equal to p?

[0157] In some embodiments, if the remaining time e after the storage and charging unit has been occupied is less than or equal to p, then the vehicle can be charged when it enters the storage and charging unit. At this time, the storage and charging unit can be reserved.

[0158] In some embodiments, if the remaining time e is less than or equal to p, step S408 is executed to reserve the integrated storage and charging machine; if the remaining time e is greater than p, step S407 is executed to indicate that the integrated storage and charging machine has been occupied.

[0159] S407: The user is prompted that "The charging station is already occupied, and the charging reservation was unsuccessful!"

[0160] Here, if the remaining time e is greater than p, it means that when the vehicle arrives at the charging station, there are still vehicles charging. Therefore, a message can be sent to the user: "The charging station is occupied, and the charging reservation was unsuccessful!" to prompt the user to choose another charging station.

[0161] The advertising screen on the S408 integrated charging station displays "Reserved!".

[0162] S409, the scheduled charging and storage unit was successfully charged.

[0163] S410, the integrated energy storage and charging unit starts to replenish the internal energy storage device, ensuring that the integrated energy storage and charging unit has sufficient power.
