A central management system capable of operating a remote sensing type battery sensor and its operation method {CENTRAL MANAGEMENT SYSTEM CAPABLE OF OPERATING REMOTE SENSING TYPE BATTERY SENSOR AND METHOD THEREOF}

The present invention relates to a central management system capable of operating a remote sensing type battery sensor and a method of operating the same.

Recently, in order to efficiently use electric energy in automobiles, a number of battery sensors for analyzing the state of the battery have been adopted, and an intelligent battery sensor (IBS) for checking the state of the battery has been applied.
Conventional battery sensors have built-in a sensor circuit for measuring battery voltage and current, and a microcomputer or DSP capable of a condition analysis logic operation, and a corresponding operation device performs an analysis of the battery state. In addition, most conventional battery sensors measure the current using the shunt method, measure the battery voltage using the connected battery voltage source, and analyze the battery charging state and aging state using the internal computing device. At this time, the parameters used for battery analysis use the parameter values previously obtained through test evaluation of the battery installed in the initial vehicle. However, if the battery parameter value differs from the initially set parameter due to a change in manufacturing date or material change even though the battery type is different, capacity change, manufacturer change, or battery of the same model, the battery sensor There is a problem that the accuracy is significantly lowered. In addition, there is a problem in that it is difficult for the user to change the parameter value of the corresponding battery sensor, and the user cannot directly check the information on the current battery state. In addition, since the battery sensor is installed by an initial vehicle manufacturer and condition analysis parameter values are input based on the battery installed in the initial vehicle, the parameter value is changed significantly when the battery life is reduced or when a new battery is replaced. There is a problem in that the accuracy is poor, and the accuracy of the battery condition analysis that is replaced with a battery other than the initially installed battery is significantly reduced.

However, most of these battery sensors are installed by manufacturers in the production stage of automobiles, and they are operated through linkage communication with VCUs or ECUs in vehicles.

In addition, since the state of the battery can be accurately determined only when the initial setting of the parameter value optimized for the corresponding battery is performed, when the battery is replaced while the vehicle is in use, there is a problem in that the accuracy of the battery is changed due to a change in characteristics of the battery.

In one embodiment of the present invention, unlike the battery sensor installed by an automobile manufacturer, the user can easily install the battery sensor on the battery, and even if the battery is replaced, the status information can be learned by analyzing the characteristics of the battery. It is intended to provide a central management system capable of operating a remote sensing type battery sensor that enables prediction of battery life based on big data based on wireless communication rather than a wired connection, and an operation method thereof.

However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, the method of operating the remote sensing type battery sensor in the central management system according to the first aspect of the present invention receives the state data of the battery sensed through the sensing module attached to the battery. And calculating data including a voltage in a stabilized state of the battery, a charging/discharging current of the battery, and a rate of change of voltage and current in the battery during startup based on the state data of the battery, and the calculated data Based on the state data analysis step of calculating the internal resistance and the state of charge of the battery as a result value, and transmitting the analyzed state data to output to a display module, wherein the state data analysis step in the sensing module Calculating a rate of change of the internal resistance of the battery at the time of starting the battery, which is collected based on the sensed state data, of the internal resistance at the time of starting the battery collected from at least one of the batteries of the same vehicle type and the batteries of the same model of another user. And calculating a rate of change, calculating a reference data value based on the calculated rate of change of internal resistance at each start-up, and analyzing an aging state of the battery based on the calculated reference data value.

Receiving the state data of the battery sensed through the sensing module attached to the battery may include receiving state data including at least one of charge/discharge current data of the battery, voltage data of the battery, and temperature data of the battery. can do.

In analyzing the sensed state data, the sensed state data may be analyzed by collecting state data sensed for batteries for the same vehicle type or for batteries for the same model.

The step of selecting the battery of another user for calculating the reference data value may be performed sequentially with the charging/discharging current data measured by the user's battery among the charging/discharging current data measured by the battery of the first selected other user. Selecting a battery having a similar data range as a battery for use as primary reference data, and temperature data measured by the user's battery among the temperature data measured by the battery of another user selected secondarily and It may include sequentially selecting a battery having a similar data range as a battery for use as secondary reference data.

An error temperature in which the temperature data during operation in the battery selected as the primary reference data is smaller than the average value of the error temperature between the other user selected as the secondary reference data and the temperature data during operation in the user's battery. If so, it can be selected as a battery for use as the primary reference data.

When the charging/discharging current data measured by the battery selected as the secondary reference data has an error smaller than the average value of the error of the charging/discharging current data measured by the user's battery, It can be selected by battery.

The selecting of the battery of another user for calculating the reference data value may include an average of charging/discharging current data and an average of temperature data in the battery selected as the primary and secondary reference data. The method may further include selecting a battery having charge/discharge current data and temperature data in the battery of another user as a battery for use as the third reference data.

In the step of selecting a battery for use as the third reference data, errors between the average of the charge/discharge current data and the average value of the temperature data are summed, and the battery of another user having the smallest total error is the third reference data. It can be selected as a battery for use.

And a memory in which a program for analyzing data is stored and a processor for executing a program stored in the memory. At this time, as the processor executes the program, it receives and analyzes the sensed battery state data through the communication module, and transmits the analyzed data to the user terminal to output to the display module of the user terminal. .

According to any one of the above-described problem solving means of the present invention, unlike the IBS initially installed and provided by an automobile manufacturer, a central management system that performs complex calculations and comparisons for battery condition analysis and data storage and analysis is provided. Separately provided, there is an advantage that the cost of vehicle-mounted parts for battery condition analysis can be reduced by mounting a telemetry sensor module that measures voltage, current, and temperature in an actual vehicle.

In addition, the sensor module solves the disadvantage that it is impossible to change the parameter value in real time for the change of battery status that is differently progressed by the existing IBS according to the battery replacement or the user's vehicle driving behavior, while solving the disadvantage that it is impossible to change the value of the analysis parameter Since it is not required as a hardware component in the module, it has the advantage that the configuration of the battery sensor itself is simple, and it is easy to install and operate even by general users.

In addition, after mounting the sensor module, there is an advantage in that it is easy to continuously display and manage the battery through a mobile device or mobile phone application linked to the central management system.

Meanwhile, in the description of the present invention, the battery sensor and the sensor module will be described as referring to the same object.

1 is a view for explaining a central management system 100 according to an embodiment of the present invention. 2 is a block diagram of a central management system 100 according to an embodiment of the present invention.

The central management system 100 according to an embodiment of the present invention includes a communication module 110, a memory 120, and a processor 130.

The communication module 110 transmits and receives data to and from the sensing module 10 and the user terminal 200 attached to the battery 20 of the vehicle. At this time, the communication module 110 may be a wireless communication module implemented with WLAN (wireless LAN), Bluetooth, HDR WPAN, UWB, ZigBee, Impulse Radio, 60GHz WPAN, Binary-CDMA, wireless USB technology and wireless HDMI technology. .

That is, it is possible to collect data sensed for batteries for the same vehicle type or batteries for the same model, which can be analyzed through the processor 130.

The memory 120 stores a program for analyzing the state data of the battery 20 sensed from the sensing module 10 (also referred to as a sensor module), and the processor 130 executes the program stored in the memory 120 .

Here, the memory 120 collectively refers to a nonvolatile storage device and a volatile storage device that continuously maintains stored information even when power is not supplied.

For example, the memory 120 may include a compact flash (CF) card, a secure digital (SD) card, a memory stick, a solid-state drive (SSD), and a micro SD card. Magnetic computer storage devices such as NAND flash memory, hard disk drives (HDD), such as cards, and optical disc drives such as CD-ROM, DVD-ROM, etc. I can.

Meanwhile, in an embodiment of the present invention, the sensing module 10 attached to the battery 20 may include a data measuring unit (not shown) and a data transmitting/receiving unit (not shown).

The data transmission/reception unit transmits the data measured by the data measurement unit to the central management system 100 through a wired or wireless network, and receives the analyzed result value from the central management system 100.

Accordingly, the central management system 100 may monitor the sensed state data of the battery 20 in real time.

In an embodiment of the present invention, the sensor module 10 is basically attached to the front or rear surface or side surfaces of the battery 20.

In particular, the sensor module 10 is preferably attached to the side of the battery 20 in a wide direction, which means that a temperature sensor for measuring the temperature is configured on the outer shape of the sensor module 10 and the corresponding temperature sensor is a battery ( This is because it is possible to estimate even the internal temperature change of the battery 20 according to the environmental temperature by directly measuring the environmental temperature of 20) and the temperature of the battery 20 itself.

Meanwhile, the user terminal 200 may be a portable terminal such as a smartphone or a tablet PC, and may also be an infotainment system installed in a vehicle. The data analyzed from the central management system 100 may be directly transmitted to a portable terminal or Bluetooth paired with a vehicle infotainment system and transmitted to the portable terminal. The transmitted data is output to the display module 30 of an application or infotainment system previously installed in the portable terminal.

For reference, the components shown in FIGS. 1 to 2 according to an embodiment of the present invention may be implemented in software or in hardware such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC). Can play roles.

Components and functions provided within the components can be combined into a smaller number of components or further separated into additional components.

Hereinafter, a method of operating the remote sensing type battery sensor 10 in the central management system 100 according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 to 8.

3 is a flowchart of a method of operating a battery sensor according to an embodiment of the present invention. 4 is a flowchart illustrating a process of analyzing an aging state of a battery based on a reference data value. 5 is a flowchart illustrating a method of selecting another user battery for calculating a reference data value. 6 is a flowchart of a method of selecting a battery corresponding to primary to tertiary reference data.

Referring to FIG. 3, in a method of operating a battery sensor according to an embodiment of the present invention, first, when a sensing module attached to a battery senses state data of a battery, the sensing data is received through the communication module 110 (S110). ).

In this case, the state data sensed through the sensing module may include one or more of charging/discharging current data of the battery, voltage data of the battery, and temperature data of the battery.

Next, the processor 130 analyzes the received state data of the battery (S120), and transmits and outputs the analyzed data to the user terminal 200 or outputs the analyzed data to the display module 30 (S130).

Specifically, the central management system 100 collects the sensed data for the battery for each vehicle type or battery for each model and analyzes the sensed state data. Based on the state data of the battery, the voltage and the It is possible to calculate the charge/discharge current and the rate of change of the voltage and current in the battery during startup. Also, based on the calculated data, the internal resistance and the state of charge of the battery may be calculated as a result value.

Here, the central management system 100 according to an embodiment of the present invention may analyze the internal resistance at the time of starting the battery, and based on this, analyze the aging state of the battery.

In this case, an embodiment of the present invention may additionally perform a process of setting a reference data value for analyzing an aging state of a battery.

Referring to FIG. 4, a rate of change of internal resistance at startup is calculated based on state data sensed by a sensor module mounted on a battery of a corresponding vehicle (S121), and a battery for the same vehicle type and a battery for the same model of another user. The rate of change of the internal resistance at the time of starting collected from one or more of the targets is calculated (S122).

Further, a reference data value may be calculated based on the calculated rate of change of the internal resistance at each start (S123), and an aging state of the battery may be analyzed based on the calculated reference data value (S124).

Hereinafter, a process of analyzing the aging state of the battery by calculating the reference data value will be described in more detail.

In order to calculate the reference data value for analyzing the aging state of the battery, the central management system 100 must collect the state data sensed by the sensor module of the battery used by a plurality of other users.

Referring to FIG. 5, first, based on user information registered in the user terminal 200 linked to the remote sensing type battery sensor module (S1221), model information of the registered vehicle is checked (S1222). Based on the vehicle model information, information on the year of the vehicle and the battery used in the vehicle may be checked (S1223).

Next, a battery usage pattern for another user who uses one or more of the same vehicle type battery and the same model battery selected based on the vehicle model information is checked (S1224).

At this time, the battery usage pattern for other users may be collected through battery status data transmitted to the central management system 100 by users in use by mounting a remote sensing type sensing module on the battery. have.

In order to calculate such a reference data value, it is necessary to perform a process of selecting a battery of another user.

Referring to FIG. 6, first, a battery of another user that satisfies the charging/discharging current data charged in the user's battery and a preset range may be primarily selected (S1231).

That is, a battery of another user having a similar value within a range within ±10% of the charging/discharging current in the battery of the user to be compared is primarily selected by the charging/discharging current of the battery measured when the other user is driving.

At this time, if there is no user having a similar value within ±10%, the range is increased to ±20%, and the battery of another user is reselected.

If other similar users are not identified even in the range of ±20%, the central management system 100 sequentially selects other users having an error range of the charge/discharge current value closest to the user's battery. And in this case, it should be able to inform the user that there may be some differences in the accuracy of the data.

If similar users are sufficiently searched within ±10% or within ±20%, proceed to the next step to select the battery of another user without a separate notification to the user.

Next, a battery of another user that satisfies the temperature data measured by the user's battery and a preset range during operation of the battery from among the batteries of the first selected user is secondarily selected (S1232). That is, among the users identified up to the previous step, a user with a temperature similar to that of the subject and the battery operation is selected.

At this time, other users whose operating temperature difference with the subject's battery is within ±10 degrees are first selected, and if there is no user within the range, the user is selected by expanding to within ±20 degrees.

If the user is not identified where the temperature difference is within ±20 degrees, the central management system 100 sequentially selects other users with the temperature range error closest to the user, and in this case, the accuracy of the data is also partially affected. You should be able to guide users that there may be differences.

Next, a process of selecting a target battery to be used as reference data for measuring the internal resistance change rate is performed among the batteries of other users selected through this step.

That is, among other users identified through the above process, the user's battery that shows the most relevant charge/discharge current characteristics and the user's battery that has the most relevant battery operating temperature range are selected as primary and secondary reference data. Will be selected.

Specifically, among the charging/discharging current data measured by the battery of another user selected first, a battery having a range sequentially similar to the charging/discharging data measured by the user's battery is selected as a battery for use as the primary reference data ( S1233).

In addition, a battery having a data range sequentially similar to the temperature data measured by the user's battery among the temperature data measured by the battery of another user selected secondary is selected as a battery for use as the secondary reference data ( S1234).

At this time, when the temperature data during operation in the battery selected as the primary reference data has an error temperature smaller than the average value of the error temperature between the other user selected as the final reference data and the operating temperature data in the user's battery Only, can be selected as a battery for use as a valid primary reference data.

In addition, even in the case of the secondary reference data, only when the charging/discharging current data measured in the battery selected as the secondary reference data has an error smaller than the average value of the error of the charging/discharging current data measured in the user's battery. , Can be selected as a battery for use as valid secondary reference data.

If the primary reference data or secondary reference data are confirmed to be valid data, each next time, another user with similar charge/discharge current characteristics and another user with a similar battery operating temperature range are reselected to It is set as reference data and secondary reference data, and it is checked whether other users fall within the valid range.

After it is confirmed that the primary and secondary reference data are valid data, a process of selecting valid tertiary reference data along with valid primary and secondary reference data is performed (S1235).

That is, a battery having the charging/discharging current data and temperature data of the battery of another user having a value that is the closest to the average of the average of the charging/discharging current data and the average of the temperature data selected as the primary and secondary reference data It is selected as a battery for use as the third reference data.

In other words, when selecting valid third-order reference data, an error compared with the average value of the operating temperature range of each other user's battery is calculated, and the error compared with the average value of the charging/discharging current of the battery is calculated, and then two errors The battery of the user with the smallest error sum added by is selected as the battery of the third reference data.

After all of the primary reference data to the tertiary reference data are calculated, the aging state of the battery is analyzed based on this.

7 is an exemplary view showing an internal resistance value and a rate of change thereof during startup. 8 is a graph showing a reference data value, first to third reference data, and a comparison thereof.

For example, assuming that there are three battery sensor modules that collect 20 changes of internal resistance values at startup collected from users who apply the same battery model, the change trend of internal resistance at the time of startup is shown in FIG. Assuming that they are configured together, the central management system 100 in which the corresponding data is collected calculates a rate of change of each data, and calculates a reference rate of change obtained by averaging the calculated rate of change of each data.

When this rate of change is applied to the average value of the initial data, it becomes a reference data value based on the rate of change of the internal resistance at startup.

By applying the reference data value for the corresponding battery calculated according to the reference value calculation method using big data in the central management system 100, and comparing it with vehicle battery information measured in real time, the current user's battery aging state And state of charge analysis is possible.

For example, if the starting resistance value of the battery measured in real time by the user's battery is a value of about 3.1mΩ, it can be seen that the value corresponds to the 12th order when the reference data value is applied in FIG. 7. Based on this, it is possible to check the degree of aging in comparison with the users of other vehicles.

In addition, if the OBD linkage device that can acquire vehicle information from the OBD terminal of the vehicle is configured so that vehicle mileage can be checked as a separate option, the average of the mileage of each sequence can be checked. It is possible to check and guide if replacement is necessary at the time.

When such an OBD linking device is used together, vehicle status information can be obtained in various ways, and when it is made available to the central management system 100, various batteries and driving behaviors of users can be analyzed.

On the other hand, in an embodiment of the present invention, it is not assumed that such an OBD linking device is necessarily provided, but if provided, there is an advantage that more detailed services can be provided.

In addition, even if other contents are omitted, the contents already described with respect to the central management system 100 in FIGS. 1 to 2 are also applied to the operating methods of FIGS. 3 to 8.
