Description

Technical Field

[0001] This invention relates to the field of electric bicycle charging technology, and in particular to an intelligent interconnection data transmission system and method for electric bicycles and integrated charging and swapping base stations. Background Technology

[0002] As of 2024, my country had approximately 420 million e-bikes. Besides short-distance daily commuting, e-bikes are experiencing rapid growth as a crucial production tool for industries such as food delivery and express delivery. Similar to new energy vehicles, e-bikes also suffer from range anxiety. For example, ordinary users may forget to charge and find their batteries low on the road, while delivery drivers typically need to carry 2-3 batteries to meet their daily needs. Currently, the main solution is to set up charging stations (including charging and swapping cabinets and charging piles) in public places. However, problems persist, such as not being able to find a station or having insufficient battery power to reach one. Furthermore, even after a fully charged e-bike has reached a charging station, it often occupies the charging station interface, preventing other users from using it and wasting charging station resources. The main reason for these problems is that the e-bikes are only drawing power from the charging station through the charger, without establishing a communication mechanism. Therefore, the system cannot accurately obtain the status of the charging station and the e-bikes being charged, resulting in the entire system's inability to accurately monitor the status of both.

[0003] Therefore, there is a need for an intelligent interconnection data transmission system and method between electric bicycles and integrated charging and swapping base stations. Summary of the Invention

[0023] The carrier communication controller is used to transmit handshake signals to the vehicle control subsystem through the transmit filter, and to receive feedback signals and data on the electric bicycle charging process sent by the vehicle control subsystem through the receive filter. Based on the data on the electric bicycle charging process, it determines whether the electric bicycle is fully charged, and transmits the collected data on the electric bicycle charging process and the determination result to the station control subsystem, as well as controlling the voltage and current of the electric bicycle charging process.

[0024] The relay is used to control whether the charging pile socket outputs 220V AC power under the control of the station control subsystem.

[0025] Preferably, the carrier communication subsystem further includes an AC / DC module, which is connected to the 220V AC power supply and the carrier communication controller respectively, and is used to convert the 220V AC power supply into a DC voltage suitable for the operation of the carrier communication controller, so as to provide working power for the carrier communication controller.

When the electric bicycle being charged in the charging and swapping station is fully charged, it sends a control signal to the carrier communication subsystem of the corresponding charging pile to disconnect the charging power of the corresponding charging pile.

[0031] On the other hand, the present invention provides a method for intelligent interconnection and data transmission between electric bicycles and integrated charging and swapping base stations, which, using the aforementioned system, includes the following steps:

[0032] The vehicle control subsystem of the electric bicycle in the charging and battery swapping station collects data on the charging process of the electric bicycle and transmits it to the carrier communication subsystem via carrier communication.

[0033] The carrier communication subsystem collects data on the charging process of electric bicycles in the charging and swapping station, and determines whether the electric bicycles are fully charged. It then transmits the collected data on the charging process and the determination results to the station control subsystem. When the electric bicycles are not fully charged, it controls the voltage and current of the charging process.

[0034] The station control subsystem is used to collect data on the number of batteries available in the battery swapping cabinets, the status data of the charging piles, the number of available charging piles, and the location data of the charging and swapping station, and upload them to the cloud platform. At the same time, when the electric bicycle is fully charged, it sends a control signal to the carrier communication subsystem, which controls the charging pile to cut off the power. The available charging pile data includes the number of charging piles that are not charging and the number of charging piles that are charging and whose corresponding electric bicycles are fully charged.

[0035] The vehicle control subsystem of the electric bicycle in operation collects the remaining battery power data of the electric bicycle in real time, and uploads the location data and battery warning information of the electric bicycle to the cloud platform when the remaining battery power of the electric bicycle is less than the set battery power value.

[0036] The cloud platform, based on the data collected and uploaded by the station control subsystem and the power warning information collected and uploaded by the vehicle control subsystem, filters the location data of the battery swapping station that meets the power warning information and has available batteries or available charging piles and sends it to the mobile terminal. It also filters the location data of the nearest charging and battery swapping station that meets the power warning information and has available batteries or available charging piles and sends it to the vehicle control subsystem. When the electric bicycle charging in the charging and battery swapping station is fully charged, the corresponding charging pile location is sent to the mobile terminal.

[0037] Maintenance personnel can use their mobile devices to view the location of the charging stations connected to fully charged e-bikes, while users can use their mobile devices to view the location data of battery swapping stations that meet the power warning information and have available batteries or charging stations.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] This invention uses a vehicle control subsystem to monitor battery level and vehicle location in real time, and a station control subsystem to monitor the number of available batteries and charging stations within the battery swapping station, as well as the location of the swapping station itself. The location of the nearest swapping station with available batteries or charging stations is then fed back to the user via a cloud platform, reminding them to charge promptly and providing the location of available charging stations. This invention reduces the time and process for users to find charging stations, alleviating range anxiety.

[0040] The carrier communication subsystem of this invention interacts with the vehicle control subsystem via carrier communication, which can adjust the charging current and charging voltage in real time, reduce energy waste, and keep the battery in the optimal charging state at all times, which is beneficial to improving battery life and charging safety.

[0041] This invention combines satellite positioning, IoT technology, and carrier communication technology to establish a closed-loop communication system connecting the cloud platform, the electric bicycles locating for charging, the integrated charging and swapping base station, and the electric bicycles currently charging. This allows the cloud platform to accurately determine the status of the charging piles at the integrated charging and swapping base station. On the one hand, it can promptly notify maintenance personnel to move vehicles to avoid occupying the space; on the other hand, it can notify users that the charging pile is available. By setting up a mobile terminal, site maintenance personnel can check in real time whether the corresponding charging pile is being used inactively, thus releasing charging pile resources promptly, improving operational efficiency, and increasing the probability of users finding an available charging pile.

[0049] Example 1:

[0050] like Figure 1 As shown, this embodiment provides an intelligent interconnection data transmission system between an electric bicycle and a charging / swapping integrated base station, including: a vehicle control subsystem and a charging / swapping integrated base station; the charging / swapping integrated base station includes a cloud platform, a station control subsystem, a carrier communication subsystem, and a mobile terminal; the vehicle control subsystem, the station control subsystem, and the mobile terminal are respectively connected to the cloud platform; the carrier communication subsystem is connected to the station control subsystem; the vehicle control subsystem is installed on the electric bicycle, the station control subsystem is installed at the charging / swapping station, and the carrier communication subsystem is installed on the charging pile; the carrier communication subsystem is detachably connected to the vehicle control subsystem of the electric bicycle being charged at the charging / swapping station.

[0051] The vehicle control subsystem is used to collect the remaining battery power data of the electric bicycle in real time when the electric bicycle is running, and upload the location data and battery warning information of the electric bicycle to the cloud platform when the remaining battery power of the electric bicycle is less than the set battery power value. It is also used to collect the charging process data of the electric bicycle when it is charging at the charging and battery swapping station, and transmit it to the carrier communication subsystem through carrier communication.

[0052] The carrier communication subsystem is used to collect data on the charging process of electric bicycles in the charging and swapping station, determine whether the electric bicycles are fully charged, transmit the collected data on the charging process and the determination results to the station control subsystem, and control whether the electric bicycles are being charged and control the voltage and current of the electric bicycles during the charging process.

[0053] The station control subsystem is used to collect data on the number of batteries available in the battery swapping cabinets, the status data of the charging piles, the number of available charging piles, and the location data of the charging and battery swapping station within the charging and battery swapping station, and upload them to the cloud platform.

[0054] The cloud platform is used to filter the location data of battery swapping stations that meet the battery warning information and have available batteries or available charging piles, and send them to the mobile terminal based on the data collected and uploaded by the station control subsystem and the power warning information collected and uploaded by the vehicle control subsystem. It also filters the location data of the nearest charging and battery swapping station that meets the battery warning information and has available batteries or available charging piles, and sends them to the vehicle control subsystem. When the electric bicycle being charged in the charging and battery swapping station is fully charged, it sends the location of the corresponding charging pile to the mobile terminal.

[0055] The mobile app is used by maintenance personnel or users to view the location of the charging piles connected to fully charged e-bikes, and by users to view the location data of battery swapping stations that meet the power warning information and have available batteries or available charging piles.

[0056] The working principle of this invention is as follows: the vehicle control subsystem monitors the battery level and vehicle location of the electric bicycle in real time. When the remaining battery level of the electric bicycle is less than the set battery level, the location data and battery warning information of the electric bicycle are uploaded to the cloud platform. The battery warning information includes the estimated remaining driving range of the electric bicycle.

[0057] The carrier communication subsystem collects data on the charging process of electric bicycles in the charging and swapping station, determines whether the electric bicycles in the charging and swapping station are fully charged, and transmits the collected data on the charging process and the determination results to the station control subsystem. It also controls whether the electric bicycles in the charging and swapping station are charging and controls the voltage and current of the electric bicycles in the charging and swapping station during the charging process. That is, when the electric bicycles in the charging and swapping station are fully charged, the determination result that the electric bicycles in the charging and swapping station are fully charged is transmitted to the station control subsystem. If the electric bicycles in the charging and swapping station are not fully charged, the voltage and current of the electric bicycles in the charging and swapping station during the charging process are controlled according to the charging status.

[0058] The station control subsystem collects real-time data on the number of available batteries in the battery swapping cabinets, the connection status of charging piles within the station, the number of available charging piles, and the location of the charging station, and uploads this data to the cloud platform. The connection status data for charging piles includes the number and details of those not charging, those charging but not fully charged, and those charging fully charged. The available charging pile data includes the number of charging piles not charging and the number of charging piles currently charging and whose corresponding connected electric bicycles are fully charged.

[0059] The cloud platform, based on data collected and uploaded by the station control subsystem and power warning information collected and uploaded by the vehicle control subsystem, filters and sends the location data of battery swapping stations that meet the power warning information and have available batteries or charging piles to the mobile terminal. It also filters and sends the location data of the nearest battery swapping station that meets the power warning information and has available batteries or charging piles to the vehicle control subsystem. Furthermore, when the electric bicycle connected to the corresponding charging pile is fully charged, the platform sends the location of the corresponding charging pile to the mobile terminal. The charging pile location sent to the mobile terminal includes the location of the battery swapping station and the charging pile number.

[0060] Maintenance personnel can use their mobile devices to check which charging stations are fully charged and still connected to the electric bicycles, and then manually disconnect the charging stations from the electric bicycles to free up charging station resources.

[0061] Users can view the locations of battery swapping stations that meet the power level warning information and have available batteries or charging piles via their mobile devices. The number of available charging piles includes the number of charging piles that are not currently charging and the number of charging piles where the corresponding e-bike is fully charged. For charging piles where the corresponding e-bike is fully charged, users can go to the corresponding charging / swapping station and have maintenance personnel manually disconnect the charging pile from the e-bike before using it.

[0062] In a preferred embodiment of the present invention, the vehicle control subsystem includes a first data acquisition module, a first processor, a first positioning module, a first communication module, and a carrier charger;

[0063] The first data acquisition module, the first positioning module, and the first communication module are respectively connected to the first processor;

[0064] The first data acquisition module is connected to the vehicle battery of the electric bicycle; the carrier charger is detachably connected to the vehicle battery of the electric bicycle; the first communication module is connected to the cloud platform.

[0065] The first data acquisition module is used to collect the remaining battery power data of the electric bicycle when it is running, and transmit the collected remaining battery power data to the first processor;

[0066] The first positioning module is used to collect the location data of the electric bicycle in real time when the electric bicycle is running, and transmit the real-time collected location data to the first processor.

[0067] The first processor is used to upload the location data and battery warning information of the electric bicycle to the cloud platform through the first communication module when the electric bicycle is running and the remaining battery power of the electric bicycle is less than the set battery power value;

[0068] The carrier charger is used to charge the vehicle battery of the electric bicycle when it is at the charging and battery swapping station, and to transmit the data of the charging process of the electric bicycle battery to the carrier communication subsystem via carrier communication, and to receive control signals sent by the carrier communication subsystem to control the charging voltage and current of the electric bicycle battery.

[0069] The working principle of the vehicle control subsystem is as follows:

[0070] The first data acquisition module collects the remaining battery power of the electric bicycle in real time and transmits it to the first processor. The first positioning module collects the location data of the electric bicycle in real time and transmits it to the first processor.

[0071] The first processor compares the remaining battery power of the electric bicycle during operation with a set battery level. When the remaining battery power of the electric bicycle is less than the set battery level, the processor uploads the real-time location data of the electric bicycle and a battery warning information to the cloud platform through the first communication module. The battery warning information includes the estimated remaining driving range.

[0072] During charging, simply connect the carrier charger to the electric bicycle's battery and charging pile within the charging / swapping station. The carrier charger connects to the carrier communication subsystem and interacts with it via carrier communication. The carrier charger collects real-time data on the electric bicycle's battery charging process and sends it to the carrier communication subsystem. This data includes: remaining battery power, battery temperature, charger charging switch status, charger charging voltage, charger charging current, charger temperature, charger charging time, charger charging capacity, and charging completion signal.

[0073] In a preferred embodiment of the present invention, the vehicle control subsystem further includes a display module, which is connected to a first processor. The first processor is also used to receive battery swapping station location data sent by the cloud platform through a first communication module. The display module is used to display the battery swapping station location sent by the cloud platform when the electric bicycle is running, so as to provide feedback to the user or to display information that the vehicle battery is low.

[0074] In a preferred embodiment of the present invention, the vehicle control subsystem further includes a horn module, which is connected to the first processor and is used to broadcast the location of the battery swapping station sent by the cloud platform to the user or to broadcast information about the low battery level of the vehicle battery when the electric bicycle is in operation.

[0075] In this embodiment, the first positioning module is a satellite positioning module. The first data acquisition module is connected to the electric bicycle's battery via an RS485 / CAN bus. The first communication module includes a 4G communication module or a 5G communication module.

[0076] In a preferred embodiment of the present invention, the carrier communication subsystem includes a carrier communication controller, a transmitting filter, a receiving filter, a charging pile socket, and a relay;

[0077] The carrier communication controller is connected to the transmit filter, receive filter, and station control subsystem, respectively.

[0078] The transmitting filter, receiving filter, and relay are connected to the charging pile socket respectively; the charging pile socket is detachably connected to the vehicle control subsystem; the relay is connected to the station control subsystem; the relay is connected to 220V AC power; the carrier communication controller is used to transmit handshake signals to the vehicle control subsystem through the transmitting filter, and to receive feedback signals and data on the electric bicycle charging process sent by the vehicle control subsystem through the receiving filter. Based on the data on the electric bicycle charging process, it determines whether the electric bicycle is fully charged, and transmits the collected data on the electric bicycle charging process and the judgment result to the station control subsystem, as well as controlling the voltage and current of the electric bicycle charging process.

[0079] The relay is used to control whether the charging pile socket outputs 220V AC power under the control of the station control subsystem.

[0080] The working principle of the carrier communication subsystem is as follows:

[0081] When the carrier charger in the vehicle control subsystem of the electric bicycle in the charging and swapping station is connected to the charging pile socket, the charging pile socket outputs 220V AC power. The carrier communication controller sends a handshake signal and modulates the handshake signal onto the 220V AC carrier through the transmission filter, and transmits it to the carrier charger through the charging cable.

[0082] The information fed back by the carrier charger is fed back to the carrier charger after the 220V AC carrier is filtered out by the receiving filter. The information fed back by the carrier charger includes the following two types:

[0083] (1) No information is returned or NAK information is returned.

[0084] If the carrier charger does not support carrier communication or the handshake signal is received incorrectly, it will not return any information or will return a NAK message. The carrier communication controller will retransmit the handshake message after an interval of T seconds. If it retransmits n times and still does not return any information or returns a NAK message, then the communication is confirmed to be abnormal. The carrier communication controller will then send a communication abnormality message to the station control subsystem, which will control the relay to disconnect, and the charging pile socket port will no longer output 220V AC power. Here, T and n are integers greater than 0 and can be configured.

[0085] (2) Return ACK information

[0086] After the carrier charger receives the handshake signal normally, it returns an ACK signal. Once the carrier communication controller receives the ACK information, it confirms that the communication connection is successful.

[0087] The carrier charger and the carrier communication controller engage in bidirectional data interaction. The carrier charger collects real-time data on the charging process of the electric bicycle's battery and sends it to the carrier charger. The carrier controller sends data / control commands to the carrier charger, including but not limited to: turning the charger charging switch on / off, increasing / decreasing the charger charging voltage, and increasing / decreasing the charger charging current.

[0088] In a preferred embodiment of the present invention, the carrier communication subsystem further includes an ACDC module. The ACDC module is connected to both the 220V AC power supply and the carrier communication controller, and is used to convert the 220V AC power supply into a DC voltage suitable for the operation of the carrier communication controller, thereby providing power to the controller. In this embodiment, the carrier communication controller is an MCU chip integrating carrier transmission and carrier reception, and may be, but is not limited to, the SC1320A chip from Socionext. The ACDC module converts the 220V AC power into 3.3V DC power to supply power to the SC1320A chip and other devices.

[0089] In a preferred embodiment of the present invention, the station control subsystem includes a second data acquisition module, a second positioning module, a second processor, and a second communication module; the second data acquisition module, the second positioning module, and the second communication module are respectively connected to the second processor, the second data acquisition module is respectively connected to a plurality of batteries in the battery swapping cabinet and a plurality of charging piles in the charging and swapping station; the second communication module is connected to the cloud platform.

[0090] The second data acquisition module is used to collect connection status data of several batteries in the battery swapping cabinet and connection status data of several charging piles in the charging and swapping station, and transmit the collected data to the second processor.

[0091] The second positioning module is used to collect the location data of the charging and battery swapping station and transmit the collected data to the second processor;

[0092] The second processor is used to obtain data on the number of available batteries and the number of available charging piles in the battery swapping station based on the data collected by the second data acquisition module, and to upload the obtained data and the location data of the charging and swapping station to the cloud platform through the second communication module. When the electric bicycle charging in the charging and swapping station is fully charged, it sends a control signal to the carrier communication subsystem of the corresponding charging pile to disconnect the charging power of the corresponding charging pile.

[0093] The working principle of the station control subsystem is as follows:

[0094] The second data acquisition module collects connection status data of several batteries in the battery swapping cabinet and connection status data of several charging piles in the charging and swapping station, and transmits the collected data to the second processor.

[0095] The second positioning module collects the location data of the battery swapping station and transmits the collected data to the second processor;

[0096] The second processor obtains data on the number of available batteries in the battery swapping cabinet and the number of available charging piles in the charging and swapping station based on the data collected by the second data acquisition module. It then uploads the obtained data and the location data of the battery swapping station to the cloud platform through the second communication module. This allows the cloud platform to filter the location data of the nearest battery swapping station with available batteries or charging piles. Additionally, when an electric bicycle charging in the charging and swapping station is fully charged, the processor sends a control signal to the relay of the carrier communication subsystem of the corresponding charging pile to disconnect the charging power supply of the corresponding charging pile socket.

[0097] In this embodiment, the second communication module includes a 4G communication module or a 5G communication module. The second positioning module uses a satellite positioning module. The second data acquisition module is connected to the carrier communication subsystems of several batteries and several charging piles in the battery swapping cabinet via an RS485 / CAN bus.

[0098] In this embodiment, the first and second communication modules are selected from the MAG SLM332X module, the first and second positioning modules are selected from the dual-mode Beidou + GPS UMW2395 module, and the first and second processors are selected from the Jerry MCU + Bluetooth + WiFi integrated processor AC7922A module.

[0099] In a preferred embodiment of the present invention, the cloud platform filters out data on battery swapping stations that meet the battery warning information, that is, within the estimated remaining driving range, there are available batteries or available charging piles. The data is then sent to the mobile terminal for the user to view, and the nearest station is pushed to the display module or horn module of the vehicle control subsystem.

[0100] The specific working principle of this invention is as follows:

[0101] The carrier communication controller collects data on the charging process of electric bicycles connected to charging piles within the charging and battery swapping station. When an electric bicycle in the station is not fully charged, the carrier controller sends data / control commands to the carrier charger. When an electric bicycle in the station is fully charged, the status of the charging pile is updated and sent to the second data acquisition module, indicating that the corresponding charging pile is in an available state.

[0102] The second processor collects the location data of the charging and battery swapping station through the second positioning module and uploads the location data of the charging and battery swapping station to the cloud platform through the second communication module.

[0103] The second processor collects connection status data of several batteries in the battery swapping cabinet and several charging piles in the charging and battery swapping station through the second data acquisition module. It then obtains data on the number of available batteries and charging piles in the battery swapping cabinet and uploads this data to the cloud platform. Specifically, the battery swapping cabinet contains several batteries. When a battery is connected to the second data acquisition module and its remaining power is greater than or equal to a set available power value, it is considered available. When a battery is disconnected from the second data acquisition module or its remaining power is less than the set available power value, it is considered unavailable. Disconnection from the second data acquisition module indicates that the battery has been swapped out, and a battery with less than the set available power value indicates that it has been removed and is being charged.

[0104] The connection status data of the charging piles includes the number and details of charging piles that are not charging, the number and details of charging piles that are charging but not fully charged, and the number and details of charging piles that are charging and fully charged. The available charging pile data includes the number of charging piles that are not charging and the number of charging piles that are charging and whose corresponding electric bicycles are fully charged.

[0105] When the second data acquisition module collects the data and judgment results from the carrier communication subsystem, if the carrier communication controller and carrier charger fail to establish a communication connection, the corresponding charging pile is available. If the carrier communication controller and carrier charger successfully establish a communication connection, but the carrier charger reports that the electric bicycle is not fully charged, the corresponding charging pile is unavailable. If the carrier communication controller and carrier charger successfully establish a communication connection, and the carrier charger reports that the electric bicycle is fully charged, the corresponding charging pile is available. In this case, the second processor and second communication module need to send the number and details of these fully charged charging piles to the cloud platform. The cloud platform then sends this information to the mobile device of the maintenance personnel so that they can manually disconnect the charging pile from the electric bicycle. Each charging pile's carrier communication controller has a corresponding identification code to identify the charging pile, facilitating the location of the charging pile for users or maintenance personnel.

[0106] The second processor pre-stores the total number of batteries and the total number of charging stations. The number of available batteries is obtained by subtracting the number of unavailable batteries from the total number of batteries, and the number of available charging stations is obtained by subtracting the number of unavailable charging stations from the total number of charging stations. The number of available charging stations includes the number of charging stations that are not charging and the number of charging stations that are charging and whose corresponding connected electric bicycles are fully charged.

[0107] The first processor collects the location data of the electric bicycles in operation in real time through the first positioning module, and uploads the location data of the electric bicycles to the cloud platform in real time through the first communication module.

[0108] The first processor collects the remaining battery power data of the running electric bicycles through the first data acquisition module, and compares the remaining battery power with a set battery power value. When the remaining battery power of the running electric bicycle is less than the set battery power value, a battery power warning message is sent to the cloud platform. The battery power warning message includes an estimated number of kilometers the electric bicycle can travel remaining.

[0109] When the cloud platform receives the battery warning information sent by the first processor, it searches for the location of charging and swapping stations with available batteries or charging piles within the estimated remaining driving distance of the electric bicycle, and sends the location data of the charging and swapping stations to the mobile terminal, as well as the location data of the charging and swapping station closest to the electric bicycle in operation to the first processor.

[0110] The first processor displays the location of the charging and battery swapping station via a display module, or announces the location of the charging and battery swapping station via a speaker module.

[0111] When the cloud platform fails to find a charging / swapping station matching the low battery warning information within the remaining driving range of the electric bicycle, it sends an alarm message to the first processor. The first processor then displays the low battery information to the user via the display module or broadcasts the low battery information via the speaker module.

[0112] Users can view the locations of available batteries or charging stations within the remaining driving range of their e-bike using their mobile devices. They can then select any of these stations to travel to, which will redirect them to a road navigation page. The user's mobile device can be a smartphone with location and navigation capabilities.

[0113] Furthermore, in the invention, the cloud platform is connected to several vehicle control subsystems, several station control subsystems, and several mobile terminals, including mobile terminals for maintenance personnel and mobile terminals for users, such as... Figure 2 As shown in the diagram, each charging pile is equipped with a carrier communication subsystem, meaning each station control subsystem is connected to several carrier communication subsystems. This invention can also install a central monitoring display screen connected to a cloud platform in the station control and monitoring room of the charging and battery swapping station to display the usage status of all charging piles and batteries in the station.

[0114] Example 2:

[0115] Based on the same inventive concept as Embodiment 1, this embodiment provides a method for intelligent interconnection and data transmission between electric bicycles and integrated charging and swapping base stations. Using the aforementioned system, the method includes the following steps:

[0116] The vehicle control subsystem of the electric bicycle in the charging and battery swapping station collects data on the charging process of the electric bicycle and transmits it to the carrier communication subsystem via carrier communication.

[0117] The carrier communication subsystem collects data on the charging process of electric bicycles in the charging and swapping station, and determines whether the electric bicycles are fully charged. It then transmits the collected data on the charging process and the determination results to the station control subsystem. When the electric bicycles are not fully charged, it controls the voltage and current of the charging process.

[0118] The station control subsystem is used to collect data on the number of batteries available in the battery swapping cabinets, the status data of the charging piles, the number of available charging piles, and the location data of the charging and swapping station, and upload them to the cloud platform. At the same time, when the electric bicycle is fully charged, it sends a control signal to the carrier communication subsystem, which controls the charging pile to cut off the power. The available charging pile data includes the number of charging piles that are not charging and the number of charging piles that are charging and whose corresponding electric bicycles are fully charged.

[0119] The vehicle control subsystem of the electric bicycle in operation collects the remaining battery power data of the electric bicycle in real time, and uploads the location data and battery warning information of the electric bicycle to the cloud platform when the remaining battery power of the electric bicycle is less than the set battery power value.

[0120] The cloud platform, based on the data collected and uploaded by the station control subsystem and the power warning information collected and uploaded by the vehicle control subsystem, filters the location data of the battery swapping station that meets the power warning information and has available batteries or available charging piles and sends it to the mobile terminal. It also filters the location data of the nearest charging and battery swapping station that meets the power warning information and has available batteries or available charging piles and sends it to the vehicle control subsystem. When the electric bicycle charging in the charging and battery swapping station is fully charged, the corresponding charging pile location is sent to the mobile terminal.

[0121] Maintenance personnel can use their mobile devices to view the location of the charging stations connected to fully charged e-bikes, while users can use their mobile devices to view the location data of battery swapping stations that meet the power warning information and have available batteries or charging stations.
