Description

Technical Field

[0001] This invention relates to a battery record management method and system for a battery power station, and particularly to a method and system for managing battery records according to the state of the battery. Background Technology

[0002] In recent years, with rising environmental awareness and advancements in electric vehicle technology, developing electric vehicles to replace traditional vehicles powered by fossil fuels has gradually become a key objective in the automotive industry, leading to the increasing popularity of electric vehicles. To improve the range and user willingness of electric vehicles, many countries and cities have begun planning to install charging stations and battery power stations in public places to provide charging or battery swapping services for electric vehicles and / or electric motorcycles, making the use of electric vehicles more convenient.

[0003] Generally, battery power stations are managed via the cloud. Battery power stations located in the same or different locations can connect to a remote server via a network. The remote server monitors and manages the operation of these battery power stations. For example, during a battery swapping operation, the battery power station transmits the battery identification data and user identification data of the corresponding battery to the remote server via the network. The remote server then determines whether to approve the battery swapping operation based on the received data. In addition, the battery power station also transmits relevant battery status information, such as charging status and battery-related records, back to the remote server via the network. The remote server can use this data for relevant management tasks, such as calculating battery lifespan and user fees.

[0004] As mentioned earlier, the remote server monitors and manages battery power stations located in the same or different locations simultaneously. Due to the large number of battery power stations, the remote server requires significant system resources to handle the corresponding workload. Furthermore, since battery power stations must transmit data while maintaining normal battery swapping operations, properly scheduling the related tasks and data transmission operations on the battery power stations, given the limited network bandwidth, becomes a crucial factor in ensuring stable system service. Summary of the Invention

[0005] In view of this, the present invention provides a battery record management method and system for battery power stations.

[0006] This invention discloses a battery record management method for a battery power station. First, a battery power station charges multiple batteries and provides them for battery exchange. For each battery charging, at a first time interval, a predetermined number of battery records are periodically retrieved from each battery, and these records are transmitted to a remote server via a network until no battery records remain unretrieved by the battery power station. Next, it is determined whether each battery has reached a fully charged state. When a first battery reaches this fully charged state, it enters a sleep state. The first battery is periodically woken up at a second time interval, and it is determined whether any battery records remain unretrieved by the battery power station. When the first battery contains a battery record that the battery energy station has not yet acquired, the first battery acquires up to the predetermined number of battery records and transmits the predetermined number of battery records to the remote server via the network.

[0007] A battery record management system for a battery power station according to an embodiment of the present invention includes a battery power station. The battery power station includes a battery storage unit, a network connection unit, and a processing unit. The battery storage unit includes a plurality of batteries. The processing unit charges the batteries and provides them for a battery exchange operation. For each of the batteries charging, the processing unit periodically obtains up to a predetermined number of battery records from each battery at a first time interval, and transmits the maximum predetermined number of battery records to a remote server via a network using the network connection unit, until there are no battery records in each battery that the battery power station has not obtained. The processing unit determines whether the charge level of each battery has reached a saturated state. When the charge level of a first battery has reached the saturated state, the processing unit causes the first battery to enter a sleep state, and periodically wakes the first battery at a second time interval, and determines whether there are any battery records in the first battery that the battery power station has not obtained. When there is a battery record in the first battery that the battery power station has not yet acquired, the processing unit acquires up to the predetermined number of battery records from the first battery and transmits the predetermined number of battery records to the remote server via the network using the network connection unit.

[0008] In some embodiments, after the processing unit obtains at most the predetermined number of battery records from each of the batteries, it deletes the obtained at most the predetermined number of battery records from each of the batteries.

[0009] In some embodiments, each of the batteries includes a battery management system for managing the battery records, and the processing unit queries the battery management system of each of the batteries to obtain information about the corresponding battery records, and obtains up to the predetermined number of battery records through the battery management system of each of the batteries.

[0010] In some embodiments, the remote server also provides a user interface for receiving settings corresponding to the first time interval and the predetermined number of transactions, and the remote server transmits the settings to the battery power station via the network.

[0011] In some embodiments, the battery record is generated when each of the batteries provides electrical power to an electric vehicle, or when each of the batteries is being charged at the battery power station or when the battery exchange operation is being performed.

[0012] The method described above can exist in the form of program code. When the program code is loaded into and executed by a machine, the machine becomes an apparatus for implementing the present invention.

[0045] Figure 5 This invention illustrates a battery record management method for a battery power station according to an embodiment of the present invention. The battery record management method for a battery power station according to an embodiment of the present invention is applicable to a battery power station.

[0046] First, as in step S502, a battery power station is used to charge multiple batteries and provide them for a battery swapping operation. It is worth noting that during the battery swapping operation, the user can place a specific battery into the battery power station. Corresponding to the battery placement, the battery power station can select one battery from among the batteries and provide the selected battery to the user. As in step S504, for each battery being charged, at a first time interval, up to a predetermined number of battery records are periodically obtained from each battery, and these up to a predetermined number of battery records are transmitted to a remote server via a network until there are no more battery records in each battery that the battery power station has not obtained. In one embodiment, the first time interval can be 5 minutes, and the predetermined number of records is 5. In other words, the battery power station obtains up to 5 battery records from individual batteries every 5 minutes and transmits these 5 records to a remote server via a network until there are no other battery records in the battery.

[0047] As mentioned earlier, the battery management system can communicate with the battery power station to perform relevant management operations on the battery. Figure 6This invention illustrates a battery record management method for a battery power station according to another embodiment of the present invention. First, as in step S602, the battery records within the battery are managed using the battery management system of the battery. Next, as in step S604, the processing unit of the battery power station queries the battery management system of the battery to obtain information about the corresponding battery records, and retrieves the battery records from the battery management system of each battery. It should be noted that, in one embodiment, after the processing unit of the battery power station retrieves the battery records from each battery, the retrieved battery records can be deleted from each battery.

[0048] Next, as in step S506, it is determined whether the charge level of each battery has reached a fully charged state. It is worth noting that in some embodiments, when the battery charge reaches a threshold value, such as 80%, it can be determined that the battery has reached a fully charged state. It should be noted that the aforementioned threshold value is merely an example in this case, and the invention is not limited thereto. When no battery has reached a fully charged state (No in step S506), the process returns to step S502. When the charge level of a first battery has reached a fully charged state (Yes in step S506), as in step S508, the fully charged first battery enters a sleep state. Next, as in step S510, the fully charged first battery is periodically woken up at a second time interval, such as 4 hours, 8 hours, 12 hours, or 24 hours, or a fixed time each day, and it is determined whether there is a battery record in the first battery that has not yet been acquired by the battery power station. When the first battery has no battery record that has not yet been acquired by the battery power station (No in step S510), the process returns to step S508. When the first battery contains battery records that the battery power station has not yet acquired (as in step S510), as in step S512, the first battery acquires up to the predetermined number of battery records and transmits these records to the remote server via the network. It is worth noting that the remote server can perform relevant management based on the acquired battery records, such as calculating battery lifespan and user fees.

[0049] Figure 7 This invention illustrates a battery record management method for a battery power station according to another embodiment of the present invention. In this embodiment, the first time interval and the predetermined number of records can be flexibly adjusted. First, as in step S702, a user interface is provided on a remote server to receive the settings for the corresponding first time interval and predetermined number of records. In other words, relevant administrators can input / select the settings for the corresponding first time interval and predetermined number of records through the user interface. Next, as in step S704, the remote server transmits the settings to the battery power station via the network. After receiving the settings, the battery power station can perform subsequent battery record management based on these settings.

[0050] Therefore, the battery record management method and system of the battery power station in this case can manage the battery records of all batteries in the battery power station according to the battery status, such as charging or fully charged, thereby increasing the reliability and stability of the system and the overall service provision.

[0051] The method, or a specific form or part thereof, of the present invention may exist in the form of program code. The program code may be contained in physical media, such as floppy disks, optical discs, hard disks, or any other machine-readable (e.g., computer-readable) storage media, or may be a computer program product, not limited to an external form. When the program code is loaded and executed by a machine, such as a computer, that machine becomes an apparatus for participating in the present invention. The program code may also be transmitted via transmission media, such as wires or cables, optical fibers, or any transmission method. When the program code is received, loaded, and executed by a machine, such as a computer, that machine becomes an apparatus for participating in the present invention. When implemented in a general-purpose processing unit, the program code, in conjunction with the processing unit, provides a unique apparatus that operates similarly to an application-specific logic circuit.
