{maintenance monitoring system of BMS state changing interaction for vehicles and charging stations}

The present invention generally relates to a technology for mutually monitoring replacement cycles for mobile devices and charging stations based on changes in the charging state of a Battery Management System (BMS).

In particular, the present invention is a phenomenon in which the charging state is deteriorated by analyzing the amount of change in the BMS charging state by continuously monitoring the charging characteristics of the charging station and the moving object in a state where a plurality of charging stations constitute a charging infrastructure for a large number of moving objects. It relates to a technology for monitoring the mutual replacement cycle of a mobile device and a charging station that detects and informs the other party of the replacement period of charging-related parts such as battery cells.

In order to reduce greenhouse gases and secure future growth engines, urban air mobility (UAM), which is operated in electric vehicles (EVs), drones, electric bicycles, electric kickboards, electric scooters, golf course carts, and amusement facilities, etc. Electric vehicles based on electric energy are rapidly spreading. These electric vehicles have a long charging time, but their use duration is short, so it is important to install a wide range of charging infrastructure, and the charging infrastructure is being expanded significantly accordingly.

Currently, a large number of electric vehicles and multiple charging stations are in operation, and it is very important to properly maintain the charging-related components installed in them. Charging-related components, especially battery cells installed in mobile devices and power circuit components installed in charging stations, deteriorate over time, and their replacement cycles must be managed.

Otherwise, not only will user claims for electric vehicles increase, but the risk of accidents will also increase. For example, devices may break down and become unusable, malfunctions may occur during the charging process, and even electric vehicles may suddenly stop on the highway or drones may fall mid-flight.

To prevent these problems from occurring, technology is needed to effectively manage the replacement cycle of charging-related parts of electric vehicles and charging stations.

Hereinafter, the present invention will be described in detail with reference to the drawings.

[Figure 1] is a diagram showing the overall configuration of a system for monitoring the replacement cycle of a mobile device and a charging station according to the present invention.

The present invention discloses a mutual replacement cycle monitoring system for mobile devices and charging stations that manages replacement cycles by observing changes in BMS charging status for a plurality of charging stations (10) and a plurality of mobile devices (20) constituting a charging infrastructure.

Referring to [Figure 1], the system for monitoring the replacement cycle of a mobile device and a charging station according to the present invention includes a charging device management unit 100 installed in the charging station 10, and a mobile device management unit 200 installed in the mobile device 20. , It is configured to include a monitoring server 300 that collects BMS charging characteristic data from these and performs replacement cycle management for the charging station 10 and the mobile unit 20 based on this.

In general, people live and work in similar patterns within a certain area, so in most cases, the electric cars, electric bicycles, electric kickboards, and electric scooters they use repeatedly use charging stations within a certain area. In addition, electric bicycles and electric kickboards are operated as a type of shared service, and in most cases, these also repeatedly use charging stations within their respective installation areas. Additionally, golf courses and amusement facilities use golf carts and urban air mobility (UAM) to ensure smooth movement of employees and users, who repeatedly use charging stations within the facility.

Accordingly, in [Figure 1], it is assumed that three mobile objects (21, 22, 23) use the charging service multiple times at two charging stations (11, 12).

The present invention takes into account the fact that the charging station 10 and the moving object 20 can track changes in characteristics of each other when repeatedly exchanging charging services over a long period of time in a certain environment. Even if the electronic devices 10 and 20 were manufactured at a similar time, the parts manufacturer and component performance are different, and the usage environment (frequency of operation, duration of one operation) of the electronic devices 10 and 20 is also different, so the replacement cycle is different. It's all different. In the past, a method was used to uniformly determine the service life of parts or devices or to replace them when a failure occurred. However, in the present invention, the replacement cycle of the charging station 10 and the moving object 20 is monitored by monitoring changes in the BMS charging status. Adopt a predictive approach.

[Figure 2] is a diagram showing the concept of general BMS (Battery Management System) charging characteristics.

Referring to [Figure 2], it is known that when charging power is supplied to a battery cell, the charging speed becomes slower as the battery cell space is filled. Accordingly, the charging process of the battery cell is divided into three sections: fast charging (Phase 1A) with 0 to 50% of the remaining battery, normal charging (Phase 1B) with 50 to 80% of the remaining battery, and 80 to 100% of the remaining battery. It is divided into battery protection (Phase 2) section. In this process, the charging power supply is switched from CC mode (Constant Current mode) to CV mode (Constant Voltage mode).

In the present invention, the concept of 'BMS charging characteristics' is used. BMS charging characteristics detect the status of charging-related components (e.g., battery cell, power transistor, etc.) during the three-section charging process of the battery cell shown in [Figure 2], and evaluate the status according to preset standards.

For example, commercial BMS control chips (e.g., Analog Devices' LTC2941) provide coulomb counting and battery temperature measurement functions, and these measurements are related to the current state of charging components. For example, Seongheum Shim and 5 others. (2013). Prediction of remaining lifespan of lithium-ion battery using charging voltage characteristics. According to the paper in Journal of the Korean Society of Mechanical Engineers B, Volume 37, Issue 4, 313-322, the remaining lifespan of a battery can be predicted using charging voltage characteristics. In this way, during the charging process, variables related to the current state of the charging-related components mounted on the charging station 10 and the mobile device 20 are measured, and these measured values are qualitatively evaluated according to preset standards to obtain, for example, grade A, The evaluation results can be graded as B or C.

When the charging station 10 charges the battery cells of the mobile device 20, these evaluation results are obtained for each of the three sections (Phase1A, Phase1B, and Phase2), which are called 'BMS charging characteristics'.

In the present invention, a structure is adopted in which the charging station 10 and the mobile unit 20 monitor each other. For example, in the case where charging station A (11) charges mobile object 3 (23) in [FIG. 1], charging station A (11) uses the evaluation result of the measurement value it obtained as a BMS for mobile object 3 (23). It is set as the charging characteristic, and Mobile 3 (23) sets the evaluation result of the measurement value it obtained as the BMS charging characteristic for charging station A (11).

The monitoring server 300 receives the BMS charging characteristics obtained in this way, continuously accumulates these BMS charging characteristics, and then compares and analyzes them to extract information related to the replacement cycle for the charging station 10 and the mobile unit 20. . For example, if the current evaluation result falls below a certain threshold, for example, 50%, compared to the previous average level, it means that the replacement time of the charging-related parts for the corresponding device, that is, the charging station 10 or the mobile device 20, is approaching. That can be judged.

[FIG. 3] is a diagram showing the concept of collecting charging record data between the charging station 10 and the mobile object 20 in the present invention, and [FIG. 4] is a diagram conceptually showing charging record data in the present invention.

First, referring to [FIG. 3], when the charging station 10 where it is installed provides charging for the mobile object 20, the charging device management unit 100 evaluates the three-zone charging state for the mobile object 20. Obtain and manage the resulting BMS charging characteristics. As described above with reference to [FIG. 2], as an example of obtaining BMS charging characteristics, the coulomb counting value and battery temperature value for each of the three sections (Phase1A, Phase1B, Phase2) are set to a preset standard while charging is performed. Depending on the evaluation, the evaluation result can be graded as, for example, A grade, B grade, or C grade. At this time, points can be assigned to each grade and displayed as numbers. The charging device management unit 100 uses the evaluation results obtained in this way as the BMS charging characteristics for the corresponding mobile object 20.

Preferably, the charging device management unit 100 obtains the BMS charging characteristics for the mobile object 20 each time a charging service is provided to the mobile object 20. The database of the plurality of BMS charging characteristics obtained in this way is stored in the monitoring server. Provided as (300). For convenience, the database of BMS charging characteristics of the mobile object 20 constructed by the charging device management unit 100 is referred to as 'station charging record data'. The charging device management unit 100 holds distributed IDs. The distributed ID of charging station A (11) is indicated as DID-A and the distributed ID of charging station B (12) is indicated as DID-B. At this time, the two station charging record data generated by charging stations A and B (11, 12) are separately identified by these distributed IDs (DID-A DB, DID-B DB).

When the mobile device 20 on which it is installed receives charging from the charging station 10, the mobile device management unit 200 obtains and manages BMS charging characteristics, which are the results of evaluating the three-zone charging state, for the charging station 10. As described above with reference to [FIG. 2], as an example of obtaining BMS charging characteristics, the coulomb counting value and battery temperature value for each of the three sections (Phase1A, Phase1B, Phase2) are set to a preset standard while charging is performed. Depending on the evaluation, the evaluation result can be graded as, for example, A grade, B grade, or C grade. The mobile vehicle management unit 200 uses the evaluation results obtained in this way as the BMS charging characteristics for the corresponding charging station 10.

The mobile management unit 200 preferably acquires the BMS charging characteristics for the charging station 10 each time charging is provided from the charging station 10, and the database of the plurality of BMS charging characteristics obtained in this way is stored in the monitoring server ( 300). For convenience, the database of BMS charging characteristics of the charging station 10 built by the mobile object management unit 200 is referred to as 'mobile object charging record data'. The mobile object management unit 200 holds distributed IDs, and the distributed IDs of mobile objects 1, 2, and 3 (21, 22, and 23) are indicated as DID-1, DID-2, and DID-3. The three mobile charging record data generated by mobile objects 1, 2, and 3 (21, 22, and 23) are separately identified by their distributed IDs (DID-1 DB, DID-2 DB, DID-3 DB).

The monitoring server 300 receives station charging record data (DID-A DB, DID-B DB) and mobile device charging record data (DID-1 DB, DID-2 DB, DID-3 DB) is provided and managed cumulatively, and the replacement cycle for the charging station 10 or the mobile unit 20 is detected based on changes in BMS charging characteristics. This replacement cycle may be a signal that it needs to be replaced right away, or it may be a signal that the time for replacement is not far away.

In the present invention, the charging station 10 and the mobile unit 20 mutually monitor the replacement cycle. That is, the replacement cycle of the mobile object 20 is monitored based on the station charging record data provided by the charging device management unit 100, and the replacement cycle of the charging station 10 is monitored based on the mobile object charging record data provided by the mobile object management unit 200. monitor. Specifically, station charging record data (DID-A DB, DID-B DB) is tracked and analyzed for each mobile object (21, 22, 23) over time to identify charging characteristic deterioration events for a specific mobile object (20). In addition, mobile charging record data (DID-1 DB, DID-2 DB, DID-3 DB) is tracked and analyzed for each charging station (11, 12) over time to determine the deterioration of charging characteristics for a specific charging station (10). Identify events. And, in response to these charging characteristic deterioration events, the replacement cycle for the corresponding charging station 10 or mobile object 20 is detected. This data analysis process is performed by the monitoring server 300. The monitoring server 300 may be implemented as a separate device, or may be functionally divided and implemented in a distributed manner between the charging device management unit 100 and the mobile vehicle management unit 200. there is.

Referring to [Figure 4], the station charging record data (DID-A DB, DID-B DB) is the mobile objects 1, 2, and 3 (21, 22, 23) acquired by charging stations A and B (11, 12), respectively. ) includes the BMS charging characteristics. Since the charging station 10 and the mobile unit 20 continuously and repeatedly exchange charging services, BMS charging characteristics generally include data for multiple times. In addition, although not shown in [FIG. 4], the mobile charging record data (DID-1 DB, DID-2 DB, DID-3 DB) is obtained by mobile objects 1, 2, and 3 (21, 22, and 23), respectively. Includes BMS charging characteristics of charging stations A and B (11, 12). Even in this case, BMS charging characteristics typically include data for multiple charging times.

[FIG. 4] (a), the monitoring server 300 stores station charging record data (DID-A DB, DID-B DB) and mobile object charging record data (DID-1 DB, DID-2 DB, DID- 3 DB) is tracked and analyzed over time to identify charging characteristic deterioration events. In addition, information about the charging state of the charging station 10 can also be obtained by comparing the BMS charging characteristics generated by charging station A (11) and charging station B (12) for the same moving object, for example, moving object 1 (21). . This does not mean a case where one or two BMS charging characteristics show differences, but a case where a certain tendency is derived from the results of a collective analysis. For example, if the BMS charging characteristics obtained by charging station A (11) are mostly poor compared to other charging stations (e.g., charging stations B to Z) for mobile object 1 (21), this means that the BMS charging characteristics of charging station A (11) are poor. It may be determined that the charging state is poor.

[FIG. 4] (b), the BMS charging characteristics of the charging station 10 are obtained from the BMS charging characteristics obtained by mobile objects 1, 2, and 3 (21, 22, 23) for the charging station 10. Lose. In addition, the monitoring server 300 uses a plurality of moving object charging record data (DID-1 DB, DID-2 DB, DID-3 DB) provided from various moving objects 21, 22, and 23 based on the same charging station 10. It is also possible to identify a charging characteristic deterioration event for a specific moving object 20 by comparing them with each other.

[Figure 5] is an exemplary diagram showing the mobile BMS charging characteristics database collected by the charging station 10 in the present invention.

Referring to [FIG. 5], the station charging record data (DID-A DB, DID-B DB) shows BMS charging characteristics over time for each moving object (21, 22, and 23), that is, three sections (Phase1A, Phase1B). , Phase2) This is a summary of the evaluation results of the charging state. The monitoring server 300 tracks and analyzes these station charging record data (DID-A DB, DID-B DB) over time for each moving object to identify charging characteristic deterioration events for a specific moving object 20, and accordingly Monitor the replacement cycle of the mobile body 20.

In addition, the monitoring server 300 compares a plurality of station charging record data (DID-A DB, DID-B DB) provided from different charging stations 10 with respect to the same mobile object 20 to determine a specific charging station ( 10), a configuration may be provided to identify a charging characteristic deterioration event. For example, if the BMS charging characteristics obtained by charging station A (11) are mostly poor compared to other charging stations (e.g., charging stations B to Z) for mobile object 1 (21), this means that the BMS charging characteristics of charging station A (11) are poor. It may be determined that the charging state is poor.

At this time, the monitoring server 300 may determine that a charging characteristic deterioration event has occurred when the BMS charging characteristics significantly deteriorate compared to the previous average level at a specific point in time. Preferably, the deterioration of charging characteristics is individually determined for each of the three sections (Phase1A, Phase1B, and Phase2), and the results are combined to determine whether a charging characteristic deterioration event has occurred. That is, the plurality of station charging record data provided from the plurality of charging stations 11 and 12 are sorted according to time progress for each moving object 21, 22, and 23, and individually for each of the three sections (Phase1A, Phase1B, and Phase2). After tracking and analyzing the evaluation results of the charging state, the section in which the charging state at a certain point in time (e.g., currently) has deteriorated by more than a preset threshold (e.g., 50%) compared to the previous average of the charging state is determined to be a preset critical section (e.g., If more than 2 sections) is found, it may be configured to identify a charging characteristic deterioration event for the corresponding mobile object 20.

[FIG. 6] is an exemplary diagram showing the charger BMS charging characteristics database collected by the mobile body 20 in the present invention.

Referring to [FIG. 6], the mobile charging record data (DID-1 DB, DID-2 DB, DID-3 DB) shows the BMS charging characteristics, that is, three sections, according to the progress of time for each charging station (11, 12). (Phase1A, Phase1B, Phase2) This is a summary of the evaluation results of the charging state. The monitoring server 300 tracks and analyzes these moving object charging record data (DID-1 DB, DID-2 DB, DID-3 DB) over time for each charging station to deteriorate charging characteristics for a specific charging station 10. Events are identified and the replacement cycle of the charging station 10 is monitored accordingly.

In addition, the monitoring server 300 compares a plurality of moving object charging record data (DID-1 DB, DID-2 DB, DID-3 DB) provided from different moving objects 20 with each other based on the same charging station 10. Thus, a configuration may be provided to identify a charging characteristic deterioration event for a specific moving object 20. For example, for charging station A (11), if the BMS charging characteristics obtained by mobile unit 1 (21) are mostly poor compared to other mobile units (e.g., mobile units 2 to 9), this means that the charging state of mobile unit 1 (21) is poor. It may be judged to be defective.

At this time, the monitoring server 300 may determine that a charging characteristic deterioration event has occurred when the BMS charging characteristics significantly deteriorate compared to the previous average level at a specific point in time. Preferably, the deterioration of charging characteristics is individually determined for each of the three sections (Phase1A, Phase1B, and Phase2), and the results are combined to determine whether a charging characteristic deterioration event has occurred. That is, the plurality of moving object charging record data provided from the plurality of moving objects 21, 22, and 23 are sorted according to the progress of time for each charging station, and the charging state evaluation results are individually obtained for each of the three sections (Phase1A, Phase1B, and Phase2). By tracking and analyzing, if a section in which the charging state at a certain point has deteriorated by more than a preset threshold (e.g., 50%) compared to the previous charging state average is found to be more than a preset threshold section (e.g., 2 sections), the charging station (10 ) can be configured to identify charging characteristics deterioration events for.

[FIG. 7] is a diagram conceptually showing the configuration of confirming the identity information of the charging station 10 and the mobile object 20 based on distributed ID in the present invention.

Decentralized Identifier (DID) is defined as ‘a globally unique identifier that does not require registration with a centralized registration agency because it is registered in distributed ledger technology or another form of decentralized network.’ Conceptually, it is managed based on blockchain. This means personally identifiable information.

The mobile units 21, 22, and 23 and the charging stations 11 and 12 each set a distributed ID that can be used as a unified user account for themselves through the DID blockchain. These distributed IDs are exchanged between the charging stations 11 and 12 and the moving objects 21, 22 and 23 during the charging process, so that each party can recognize each other's DID. At this time, the devices 10 and 20 may be configured to be authenticated with each other using proofs such as a charging card, electronic signature, and unique identification information. As shown in [FIGS. 3] to [FIG. 6], the monitoring server 300 manages charging record data according to the corresponding DID value. Additionally, preferably, the monitoring server 300 may utilize the DID in the process of verifying the truth or integrity of the charging record data.
