Description

A central management system capable of operating a remote sensing type battery sensor and its operating 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 its operating method.

Recently, for efficient use of electric energy in automobiles, a large number of battery sensors have been employed to analyze the condition of batteries, and an intelligent battery sensor (IBS) for checking the battery condition has been applied.

However, such a battery sensor is mostly installed by a manufacturer in the production stage of a vehicle, and is operated through a communication with a VCU or an ECU in a vehicle.

In addition, since it is possible to accurately determine the state of the battery only when the initial setting is performed with the parameter value optimized for the corresponding battery, when the battery is replaced during vehicle use, a characteristic change of the battery occurs and accuracy is deteriorated.

According to an embodiment of the present invention, unlike a battery sensor mounted by an automobile manufacturer, a user can easily mount a battery sensor on a battery, and even if the battery is replaced, it is possible to analyze the characteristics of the battery and learn status information. 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 a method of operating the same.

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 technical problem, a method of operating a remote sensing type battery sensor in a central management system according to the first aspect of the present invention receives status data of a battery sensed through a sensing module attached to the battery. To do; And analyzing the sensed state data and transmitting the analyzed data to a display module.

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

In the analyzing of the sensed state data, the sensed state data may be analyzed by collecting sensed state data for a battery of the same model or a battery of the same model.

The method may further include monitoring the sensed battery status data in real time.

The step of analyzing the sensed state data may calculate a voltage in a stabilized state of the battery, a charge/discharge current of the battery, and a voltage and current change rate in the battery at startup based on the state data of the battery, Based on the calculated data, the internal resistance and charging state of the battery may be calculated as a result value.

The analyzing of the sensed state data may analyze an internal resistance at the start of the battery, and analyze the aging state of the battery based on this.

The analyzing of the sensed state data may include: calculating a change rate of internal resistance at the start-up collected based on the sensed state data from the sensor module; Calculating a rate of change of internal resistance at start-up collected from one or more objects of a battery of the same model and a battery of the same model of another user; The method may include calculating a reference data value based on the calculated change rate of internal resistance at each start-up and analyzing the aging state of the battery based on the calculated reference data value.

The step of calculating the rate of change of internal resistance at start-up collected from one or more targets of the battery of the same vehicle type and the battery of the same model of the other user may include: checking user information registered in the user terminal; Checking model information of a registered vehicle based on the user information; Checking the information of the vehicle's age and used batteries based on the vehicle model information, and based on the vehicle model information, of the battery for the other user using one or more of the same vehicle type battery and the same model battery. It may include the step of checking the usage pattern.

The step of calculating the rate of change of internal resistance at start-up collected from one or more targets of the battery of the same vehicle type and the battery of the same model of the other user may include selecting a battery of the other user for calculating the reference data value. In addition, the step of first selecting the battery of the other user that satisfies the preset range and the charge/discharge current data measured by the user's battery and the battery of the user of the first selected other user, from the battery of the user And secondly selecting a battery of the other user that satisfies the measured temperature data and a preset range during battery operation.

The step of selecting the other user's battery for calculating the reference data value may include sequentially charging and discharging current data measured by the user's battery among charging and discharging current data measured by the first selected other user's battery. 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 temperature data during battery operation measured by the battery of the second selected other user It may include sequentially selecting a battery having a similar data range as a battery for use as secondary reference data.

The temperature of the operating temperature in the battery selected as the primary reference data is smaller than the average value of the error temperature between the operating temperature in the battery of other users and users selected as the secondary reference data. If so, it can be selected as a battery for use as the primary reference data.

When the charge/discharge current data measured by the battery selected as the secondary reference data has an error smaller than the average value of the errors for the charge/discharge current data measured by the user's battery, the second reference data It can be selected as a battery.

The step of selecting the other user's battery for calculating the reference data value has a value closest to the average of the charge and discharge current data and the average of the 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 from another user's battery as a battery for use as third reference data.

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

In addition, the central management system for operating a remote sensing type battery sensor according to the second aspect of the present invention includes a sensing module attached to a battery of a vehicle, a communication module transmitting and receiving data to and from a user terminal, and a state of the battery sensed from the sensing module. It includes a memory for storing a program for analyzing data and a processor for executing the program stored in the memory. At this time, as the processor executes the program, it receives and analyzes the status data of the sensed battery through the communication module, transmits the analyzed data to the user terminal, and outputs it 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 provided initially by the automobile manufacturer, a central management system for performing complex calculations and comparisons for battery status analysis and data storage and analysis Separately provided, the actual vehicle has the advantage of being able to reduce the price of vehicle-mounted components for battery condition analysis by mounting a telemetry-type sensor module that measures voltage, current, and temperature.

In addition, the sensor module solves the disadvantage that it is impossible to change the analysis parameter value in real time for changes in the battery state that the existing IBS is changing according to the battery replacement or the user's vehicle driving behavior, but also sensors complex computation and memory for this. Since it is not required as a hardware part in the module, the configuration of the battery sensor itself is simple, and even an ordinary user can easily install and operate.

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

This point can be expected to have the effect of reducing the inconvenience such as poor vehicle starting efficiency as well as the efficiency of driving the vehicle by allowing the user to intuitively check the state of the vehicle battery and recognize the timing of replacement or failure. Can.

The existing battery sensor has a built-in sensor circuit for measuring battery voltage and current, and a microcomputer or DSP capable of calculating the state analysis logic, and performs analysis on the battery state in the corresponding computing device.

However, since the corresponding battery sensor is installed by the initial automobile manufacturer and the state analysis parameter value is input based on the battery installed in the initial vehicle, if the characteristic change occurs significantly due to the decrease in battery life or is replaced with a new battery, The accuracy decreases, and if the battery is replaced with a third-party battery instead of the initially installed battery, the accuracy of battery condition analysis is significantly reduced.

Meanwhile, most of the existing battery sensors measure current using a shunt method, and measure battery voltage using a connected battery voltage source.

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.

That is, data sensed for a battery of the same model or a battery of the same model may be collected, and this may be analyzed through the processor 130.

A program for analyzing state data of the battery 20 sensed from the sensing module 10 is stored in the memory 120, and the processor 130 executes the program stored in the memory 120.

Here, the memory 120 is a non-volatile storage device and a volatile storage device that keeps stored information even when power is not supplied.

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

At this time, the state data sensed through the sensing module may include one or more of charge/discharge 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 the analyzed data to the user terminal 200 for output or output to the display module 30 (S130).

Specifically, the central management system 100 analyzes the sensed state data by collecting the sensed data for the battery of the same vehicle or the battery of each model, based on the state data of the battery, the voltage in the stabilized state of the battery, the battery The charge and discharge current and the rate of change of the voltage and current in the battery at start-up can be calculated. And based on the calculated data, the internal resistance and charging state of the battery can 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 start of the battery, and analyze the aging state of the battery based on this.

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

Referring to FIG. 4, the change rate of internal resistance at start-up collected based on the state data sensed by the sensor module mounted on the battery of the corresponding vehicle is calculated (S121 ), and batteries of the same vehicle and batteries of the same model of other users The rate of change of internal resistance at start-up collected from one or more objects is calculated (S122).

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

Hereinafter, the 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 sensed state data from 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 associated with the remote sensing type battery sensor module (S1221 ), model information of the registered vehicle is checked (S1222 ). Based on the vehicle model information, the year of the vehicle and information of the battery used in the vehicle may be checked (S1223).

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

At this time, the battery usage pattern for other users may be collected through the state data of the battery delivered to the central management system 100 through the mobile device 200 by users who are using the remote sensing type sensing module mounted on the battery. have.

In order to calculate the reference data value, a process of selecting a battery of another user must be performed.

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

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

At this time, if no user has a similar value within the range of ±10%, the range is increased to ±20% to reselect another user's battery.

If other similar users are not identified 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 guide the user that there may be some differences in the accuracy of the data.

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

Next, the battery of another user that satisfies a preset range and temperature data when operating the battery measured from the user's battery is selected second among the batteries of the other users that are first selected (S1232). That is, among the users identified by the previous step, a user having a similar temperature when operating the battery is selected.

At this time, other users whose operating temperature difference with the battery of the subject is within ±10 degrees are first selected, and if there is no user in the range, the user is selected by expanding 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 having the temperature range error closest to the user, and in this case, some of the accuracy of data It should be able to guide the user that there may be differences.

Next, a process of selecting a target battery for use as reference data for measuring the rate of change of the internal resistance among the batteries of other users selected through these steps is performed.

That is, the user's battery having the most essential charge/discharge current characteristics and the battery of the user having the most essential battery operating temperature range are selected as the primary reference data and the secondary reference data. Will be selected.

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

In addition, a battery having a data range that is sequentially similar to the temperature data measured in the user's battery among the temperature data measured during operation of the battery measured in the battery of the second selected other user is selected as the battery for use as the secondary reference data ( S1234).

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

Also, in the case of the secondary reference data, only when the charge/discharge current data measured in the battery selected as the secondary reference data has an error smaller than the average value of the errors in the charge/discharge current data measured in the user's battery , It can be selected as a battery for use as valid secondary reference data.

If it is determined that the primary reference data or the secondary reference data are valid data, the first user is selected by re-selecting another user having a similar charge/discharge current characteristic next time, and another user having a similar battery operating temperature range next time. It is set as reference data and secondary reference data, and it is checked whether it is another user within the valid range.

After confirming that the primary and secondary reference data are valid data, a process of selecting valid primary and secondary reference data as well as valid tertiary reference data is performed (S1235).

That is, a battery having charge/discharge current data and temperature data from another user's battery having a value closest to the average of the temperature data and the average of the charge/discharge current data in the battery selected as the primary and secondary reference data It is selected as a battery for use as tertiary reference data.

In other words, when selecting valid third-order reference data, an error is compared with the average value of the operating temperature range of the battery of each other user, and an error is compared with the average value of the charge/discharge current of the battery. The user's battery with the smallest error sum is selected as the battery of the 3rd reference data.

After all 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 during startup. 8 is a graph comparing the reference data values with the primary to tertiary reference data and the same.

For example, it is assumed that there are three battery sensor modules collecting 20 changes in the internal resistance value at start-up collected from a user who applies the same battery model, and the change trend of the internal resistance at the start is shown in FIG. 7. If 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 by averaging the 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 the 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 charging status analysis is possible.

For example, if the starting resistance value of the battery measured in real time from the user battery is a value of about 3.1 mΩ, it can be seen that when applying the reference data value in FIG. Based on this, it is possible to check the degree of aging progress compared to other vehicle users.

In addition, by configuring an OBD linkage device capable of acquiring vehicle information from the vehicle's OBD terminal, so that the vehicle mileage can be checked as a separate option, the average mileage of each sequence can be checked. At this point, it is possible to check and guide whether a replacement is necessary.

When these OBD-linked devices are used together, vehicle status information can be obtained in a variety of ways, and if it can be used in the central management system 100, various battery and user driving behaviors can be analyzed.

Meanwhile, in one embodiment of the present invention, it is not assumed that the OBD linkage device is necessarily provided, but when provided, it has an advantage that more detailed service can be provided.
