FIG.3is a diagram schematically showing an apparatus for providing battery information100according to an embodiment of the present disclosure.FIG.4is a diagram schematically showing a connection configuration of the apparatus for providing battery information100according to an embodiment of the present disclosure and a battery management system200.

Referring toFIG.3, the apparatus for providing battery information100according to an embodiment of the present disclosure may include a first communication unit110, a second communication unit120, and a data conversion unit130.

The first communication unit110may be configured to receive first battery information related to a battery from the battery management system200by using a first communication protocol.

Here, the first communication protocol is a communication protocol for data communication between the first communication unit110and the battery management system200. For example, the first communication protocol may be a Modbus TCP communication protocol.

For example, in the embodiment ofFIG.4, the battery management system200and the first communication unit110may be connected to each other. Here, the battery management system200and the first communication unit110may be connected by wire and/or wirelessly, and data communication may be performed using the first communication protocol.

The second communication unit120may be configured to receive second battery information related to the battery and different from the first battery information from the battery management system200by using a second communication protocol different from the first communication protocol.

Here, the second communication protocol is a communication protocol for data communication between the second communication unit120and the battery management system200. In addition, the second communication protocol is a communication protocol different from the first communication protocol. For example, the second communication protocol may be a CAN communication protocol.

For example, in the embodiment ofFIG.4, the battery management system200and the second communication unit120may be connected to each other. Here, the battery management system200and the second communication unit120may be connected by wire and/or wirelessly, and data communication may be performed using the second communication protocol.

In addition, the second battery information that the second communication unit120receives from the battery management system200may be information different from the first battery information that the first communication unit110receives from the battery management system200. That is, the first communication unit110and the second communication unit120may be configured to receive battery information optimized for the applied communication protocol from the battery management system200, respectively.

The data conversion unit130may be configured to be connected to the first communication unit110and the second communication unit120.

Specifically, the data conversion unit130may be connected to enable communication with both the first communication unit110and the second communication unit120.

For example, in the embodiment ofFIG.4, the data conversion unit130may be connected to the first communication unit110and the second communication unit120. In addition, the data conversion unit130may receive the first battery information from the first communication unit110and receive the second battery information from the second communication unit120.

The data conversion unit130may be configured to obtain first conversion information by converting the first battery information into a predetermined data structure.

Specifically, the data conversion unit130may obtain the first conversion information by converting the first battery information received from the first communication unit110to correspond to a predetermined data structure.

In addition, the data conversion unit130may be configured to obtain second conversion information by converting the second battery information into the predetermined data structure.

Specifically, the data conversion unit130may obtain the second conversion information by converting the second battery information received from the second communication unit120to correspond to the predetermined data structure.

That is, the data conversion unit130may convert the first battery information received from the first communication unit110and the second battery information received from the second communication unit120into information having the same data structure.

Therefore, since the first battery information received by the first communication unit110from the battery management system using the first communication protocol and the second battery information received by the second communication unit120from the battery management system using the second communication protocol are converted by the data conversion unit130to have the same data structure, the data format may be unified.

The data conversion unit130may be configured to output the first conversion information and the second conversion information.

For example, the data conversion unit130may output and store the first conversion information and the second conversion information having the same data structure.

That is, the data conversion unit130may convert the first battery information and the second battery information having different data structures into the first conversion information and the second conversion information having the same data structure and then output them.

Therefore, the apparatus for providing battery information100according to an embodiment of the present disclosure may receive battery-related information from the battery management system200by using both the first communication protocol with high communication efficiency for the first battery information and the second communication protocol with high communication efficiency for the second battery information.

In addition, since the apparatus for providing battery information100may convert the first battery information and the second battery information into the same data structure, the battery information respectively received using the first communication protocol and the second communication protocol may be integrally managed.

Meanwhile, the data conversion unit130provided to the apparatus for providing battery information100may selectively include processors known in the art, application-specific integrated circuit (ASIC), other chipsets, logic circuits, registers, communication modems, data processing devices, and the like to execute various control logic performed in the present disclosure. Also, when the control logic is implemented in software, the data conversion unit130may be implemented as a set of program modules. At this time, the program module may be stored in a memory and executed by the data conversion unit130. The memory may be located inside or out of the data conversion unit130and may be connected to the data conversion unit130by various well-known means.

FIG.5is a diagram schematically showing a data structure of conversion information, which is converted by the apparatus for providing battery information100according to an embodiment of the present disclosure.

Referring toFIG.5, the predetermined data structure may be configured as a structure including at least one of a target information field131, an identification information field132, and a battery information value field133.

The target information may be information for identifying a battery that is a target of the battery information received from the battery management system200. In addition, the target information field131may be a data space in which the target information may be included.

For example, the target information may include an ID of a battery cell, an ID of a battery module, an ID of a battery rack, or the like. Specifically, the target information may include a first battery cell, a second battery cell, a first battery module, a second battery module, a first battery rack, a second battery rack, or the like.

Here, the battery cell refers to one independent cell that includes a negative electrode terminal and a positive electrode terminal and is physically separable. For example, one pouch-type lithium polymer cell may be regarded as a battery cell. In addition, the battery module refers to a cell assembly in which one or more battery cells are connected in series and/or in parallel. In addition, the battery rack refers to a cell assembly including one or more battery modules in a housing.

The identification information may be information indicating a classification item of the battery information received from the battery management system200. In addition, the identification information field132may be a data space in which the identification information may be included.

For example, the identification information may include battery state information, battery diagnosis information, battery system information, battery-related control information, or the like.

The value of the battery information may be information indicating contents of the battery information received from the battery management system200. In addition, the value field133may be a data space in which the value of the battery information may be included.

For example, the value of the battery information may include a current value, a voltage value, a temperature value, an SOC, an SOH, or the like, which indicates state information of the battery, and may include battery diagnosis state information such as an overcharge state or an overdischarge state. In addition, the battery information value may include detailed contents of the battery system information and the battery-related control information.

In addition, although only the target information field131, the identification information field132and the value field133are included in the data structure ofFIG.5, it should be noted that various fields for the battery information such as a field indicating a storage location of the battery information and a field indicating the size of battery information may be further included.

The data conversion unit130may be configured to convert the first battery information and the second battery information to correspond to the predetermined data structure.

The data structure of the first battery information received using the first communication protocol and the second battery information received using the second communication protocol from the battery management system200may be different from each other. Accordingly, the apparatus for providing battery information100has an advantage of integrally managing the first conversion information and the second conversion information by converting the first battery information and the second battery information into a common data format (the predetermined data structure).

That is, the apparatus for providing battery information100has an advantage of more easily managing the battery information received using a plurality of different communication protocols since it manages the first battery information and the second battery information using a unified data structure, without converting and managing the first battery information and the second battery information into different data structures.

The apparatus for providing battery information100according to an embodiment of the present disclosure may further include a storage unit140configured to receive and store the first conversion information and the second conversion information from the data conversion unit130.

For example, in the embodiments ofFIGS.3and4, the storage unit140may be further included in the apparatus for providing battery information100. In addition, the storage unit140may be connected to the data conversion unit130to store the first conversion information and the second conversion information output from the data conversion unit130.

Here, the storage unit140is not particularly limited in its kind as long as it is a known information storage means that can record, erase, update and read data. As an example, the information storage means may include RAM, flash memory, ROM, EEPROM, registers, and the like. In addition, the storage unit140may store program codes in which processes executable by the data conversion unit130are defined.

The data conversion unit130may be configured to store conversion information corresponding to the target information to be associated with each other in the storage unit140.

Specifically, the data conversion unit130may check the target information included in the target information field131of the first conversion information, check the target information included in the target information field131of the second conversion information, and store conversion information including the same target information to be associated with each other in the storage unit140.

For example, it is assumed that the target information included in the target information field131of the first conversion information is the first battery cell, and the target information included in the target information field131of the second conversion information is the first battery cell. The data conversion unit130may store the first conversion information and the second conversion information including the first battery cell, which is common target information, to be associated with each other in the storage unit140.

Accordingly, since the battery information received through different communication protocols is converted into the same data structure and then stored to be associated with each other, battery-related information may be managed and processed more easily.

The first communication unit110may be configured to receive the first battery information corresponding to the information provision request from the battery management system200, only when an information provision request for the first battery information is sent to the battery management system200.

Specifically, the first communication unit110may send an information provision request for the first battery information to the battery management system200by using the first communication protocol. After that, the first communication unit110may receive the first battery information from the battery management system200by using the first communication protocol.

For example, the first communication protocol may be a communication protocol employing a request-response method such as Modbus TCP communication protocol.

In the information provision request sent by the first communication unit110, the target information and the identification information for the first battery information may be designated. That is, the first communication unit110may send the information provision request for the first battery information to the battery management system200after designating the target information and the identification information of the first battery information that is a target of the information provision request.

For example, when the first communication unit110intends to receive the voltage information for the first battery cell, the information provision request sent by the first communication unit110to the battery management system200may include the first battery cell as the target information and include the voltage information as the identification information. After that, the first communication unit110may receive the first battery information from the battery management system, and the data conversion unit130may convert the first battery information into first conversion information. In this case, the target information field131of the first conversion information may include “first battery cell”, the identification information field132may include “voltage information”, and the value field133may include the voltage value of, for example, “3.8 [V]”.

Preferably, the first communication unit110may be configured to send the information provision request for the first battery information at every predetermined cycle or only when there is a request from the data conversion unit130.

Specifically, the first communication unit110may send the information provision request for the first battery information to the battery management system200at every predetermined cycle, and receive the first battery information as a response thereto.

In addition, even when there is a request from the data conversion unit130, the first communication unit110may send the information provision request for the first battery information to the battery management system200, and receive the first battery information as a response thereto. In this case, the target information and the identification information included in the first battery information may be designated by the data conversion unit130.

Meanwhile, the second communication unit120may be configured to receive the second battery information from the battery management system200by using the second communication protocol even if the information provision request for the second battery information is not sent to the battery management system200.

For example, the second communication protocol may be a communication protocol that does not employ a request-response method, such as a CAN communication protocol.

Accordingly, the second communication unit120may receive the second battery information from the battery management system200even if a separate information provision request for the second battery information is not sent to the battery management system200.

The first battery information and the second battery information may be classified in consideration of whether or not the information requires real-time processing. Here, whether real-time processing is required may be set according to whether it is required that the process until the battery information obtained by the battery management system200is provided to the apparatus for providing battery information100should be performed in real time.

Preferably, the first battery information may have a lower demand for real-time processing than the second battery information. That is, the second battery information may be information that should be sent to the apparatus for providing battery information100immediately after being obtained by the battery management system200, even if there is no separate request.

For example, the first battery information may be battery state information including at least one of voltage, current, temperature, SOC and SOH of the battery.

In addition, the second battery information may include at least one of battery system information, battery diagnosis information and battery-related control information.

The battery system information may be information provided when the battery management system200and the apparatus for providing battery information100are connected first. For example, the battery system information may include information on the battery management system200such as manufacturing date of the battery management system200, serial number, software version, hardware version, the number of battery racks in operation, the number of battery modules in operation, the number of battery cells in operation, and the type of battery cells.

The battery diagnosis information may be diagnosis information on a battery (a battery rack, a battery module and/or a battery cell) operating in the battery management system200. For example, the battery diagnosis information may include information indicating battery states such as a normal state, a high voltage state, a low voltage state, an overcharge state, an overdischarge state, a high temperature state and a low temperature state.

The battery-related control information may be control command information for the battery management system200or control command information by the battery management system200. For example, the battery-related control information may include control command information for the battery management system200such as a start command information, an end command information and a standby command information for the battery management system200, and control command information by the battery management system200such as an air conditioner operation command and a relay operation state switching command.

The second battery information (battery system information, battery diagnosis information, and battery-related control information) has a smaller capacity than the first battery information (battery state information), but requires real-time processing.

For example, referring toFIGS.1and2, the battery diagnosis information such as error information is information that should be provided to the apparatus for providing battery information100as soon as it is checked by the battery management system200. Accordingly, the apparatus for providing battery information100may receive the second battery information from the battery management system200by using the second communication protocol.

Meanwhile, the battery state information such as battery voltage information is information that is unlikely to cause a fatal defect even if the battery management system200checks it only when there is an information provision request. Also, in general, the capacity of the first battery information may be greater than the capacity of the second battery information.

Therefore, if the first battery information having a relatively larger capacity than the second battery information and not necessarily requiring real-time processing makes communication by using the second communication protocol, system resources for communication between the battery management system200and the apparatus for providing battery information100may be wasted. To solve this problem, the apparatus for providing battery information100may receive the first battery information from the battery management system200by using the first communication protocol.

That is, the apparatus for providing battery information100according to an embodiment of the present disclosure has an advantage of creating an optimized communication environment for each of the first battery information and the second battery information by communicating with the battery management system200through a plurality of communication protocols.

The first battery information may be configured to be distinguished from the second battery information based on capacity. For example, the first battery information may be configured to have a larger capacity than the second battery information.

Specifically, the first battery information and the second battery information may be configured to be distinguished according to a data transmission speed of the second communication protocol. That is, the first battery information and the second battery information may be distinguished based on data transmission capacity per second of the second communication protocol.

The data transmission speed of the first communication protocol may be faster than the data transmission speed of the second communication protocol. For example, the data transmission speed of the first communication protocol may be 100 Mbps at maximum, and the data transmission speed of the second communication protocol may be 1 Mbps at maximum.

Preferably, the capacity of the first battery information may be greater than the capacity of the second battery information, smaller than the data transmission capacity per second (e.g., 100 Mbit) of the first communication protocol, and greater than the data transmission capacity per second (e.g., 1 Mbit) of the second communication protocol. In addition, the capacity of the second battery information may be smaller than the data transmission capacity per second (e.g., 1 Mbit) of the second communication protocol.

For example, it is assumed that the battery management system200is connected to 15,000 battery cells. The battery management system200may send the first battery information including voltage information, current information and temperature information of each of 15,000 battery cells to the apparatus for providing battery information100. In addition, it is assumed that each of the voltage information, the current information and the temperature information has a size of 32 bits (4 bytes). In this case, the capacity of the first battery information sent by the battery management system200may be 1.44 Mbit (32 bit×3×15,000).

In the above example, if the battery management system200sends the first battery information to the apparatus for providing battery information100by using the second communication protocol, there may be a problem in that all of the first battery information cannot be sent at once. That is, since the data transmission capacity per second (e.g., 1 Mbit) of the second communication protocol is smaller than the capacity of the first battery information (e.g., 1.44 Mbit), the battery management system200should send the first battery information to the apparatus for providing battery information100in twice by using the second communication protocol. Therefore, unless the first battery information and the second battery information, which may be distinguished according to capacity, are sent to the apparatus for providing battery information100using different communication protocols respectively corresponding thereto, system resources for communication may be severely wasted.

The apparatus for providing battery information100according to an embodiment of the present disclosure may classify the first battery information and the second battery information according to capacity in consideration of the data transmission speed of the first communication protocol and the data transmission speed of the second communication protocol. Accordingly, the apparatus for providing battery information100may perform efficient communication by receiving the first battery information and the second battery information from the battery management system200by using communication protocols respectively corresponding thereto. Therefore, system resources required for communication between the battery management system200and the apparatus for providing battery information100may be efficiently utilized, thereby preventing the system resources from being wasted.

FIG.6is a diagram schematically showing an example of a communication process of the apparatus for providing battery information100according to an embodiment of the present disclosure and the battery management system200.

The data conversion unit130may be configured to send a request for the first battery information corresponding to the second conversion information to the first communication unit110, if the identification information of the second conversion information meets a predetermined condition as the battery diagnosis information.

Specifically, if the identification information of the second conversion information is the battery diagnosis information, the data conversion unit130may check the value of the battery information included in the value field133of the second conversion information. If the value of the battery information of the second conversion information does not indicate a normal state, the data conversion unit130may determine that the predetermined condition is met.

That is, if the identification information of the second conversion information is the battery diagnosis information and the value of the battery information is not a normal state, the data conversion unit130may send a request for the first battery information to the first communication unit110. Specifically, the data conversion unit130may send a request for first battery information corresponding to the value of the battery information of the second conversion information to the first communication unit110.

For example, in the embodiment ofFIG.6, the target information of the second conversion information may be “first battery”, the identification information may be “battery diagnosis information”, and the value of the battery information may be “overvoltage”. Even though the identification information of the second conversion information is “battery diagnosis information”, since the value of the battery information is not “normal state”, the data conversion unit130may send a request for the first battery information corresponding to “overvoltage (the value of the battery information of the second conversion information)” to the first communication unit110.

The first communication unit110may be configured to send an information provision request for the first battery information to the battery management system200after receiving the request for the first battery information from the data conversion unit130.

The request for the first battery information received from the data conversion unit130by the first communication unit110may include the target information and the identification information, which should be included in the first battery information. Here, the identification information may be information corresponding to the value of the battery information of the second conversion information.

For example, in the embodiment ofFIG.6, the request for the first battery information sent to the first communication unit110by the data conversion unit130may include the voltage information of the first battery.

In another embodiment, if “overcurrent” is included in the value of the battery information of the second conversion information, the request for the first battery information sent to the first communication unit110by the data conversion unit130may include the current information of the first battery.

In still another embodiment, if “high temperature” is included in the value of the battery information of the second conversion information, the request for the first battery information sent to the first communication unit110by the data conversion unit130may include the temperature information of the first battery.

After that, if the first communication unit110receives the first battery information from the battery management system200, the data conversion unit130may obtain the first conversion information by receiving the first battery information from the first communication unit110.

For example, in the embodiment ofFIG.6, the first conversion information may include “first battery” as the target information, include “battery state information (specifically, battery voltage information)” as the identification information, and include “4.2 [V]” as the value of the battery information.

After that, the data conversion unit130may store the first conversion information and the second conversion information with the same target information as “first battery” in the storage unit140to be associated with each other.

Through this process, the apparatus for providing battery information100according to an embodiment of the present disclosure may determine the first battery information, which is to be requested to be provided to the battery management system200, based on the second battery information received in advance. Accordingly, since the first battery information and the second battery information related to each other are stored in association with each other, battery-related information may be managed more efficiently.

The apparatus for providing battery information100according to an embodiment of the present disclosure may further include a decoding unit150configured to obtain first decoding information and second decoding information by decoding the first conversion information and the second conversion information, respectively.

Here, the decoding information refers to information obtained by decoding the conversion information into characters, symbols, numbers and/or figures to be provided to a user.

Referring toFIGS.3and4, the apparatus for providing battery information100may further include a decoding unit150, and the decoding unit150may be communicatively connected to the data conversion unit130. The decoding unit150may receive at least one of the first conversion information and the second conversion information output from the data conversion unit130and decode the received conversion information to obtain first decoding information and/or second decoding information.

For example, in the embodiment ofFIG.6, for convenience of explanation, it is shown that the second conversion information includes “first battery” as the target information, “battery diagnosis information” as the identification information, and “overvoltage” as the value of the battery information. However, in fact, the conversion information may take the form of a system code used in the apparatus for providing battery information100. For example, the conversion information may include a hexadecimal system code such as 0x01, 0xD431, and 0x31.

That is, the decoding unit150may obtain decoding information, which may be checked by a user, by decoding a system code included in the conversion information.

The decoding unit150may be configured to output the first decoding information and the second decoding information.

For example, in the embodiment ofFIG.4, the decoding unit150may be communicatively connected with the storage unit140. In addition, the decoding unit150may output the first decoding information and the second decoding information to be stored in the storage unit140. Preferably, like the data conversion unit130, the decoding unit150may store the decoding information having the same target information to be associated with each other.

Referring toFIGS.3and4further, the apparatus for providing battery information100according to an embodiment of the present disclosure may further include a display unit160.

The display unit160may be communicatively connected to the decoding unit150. The display unit160may be configured to receive the first decoding information and the second decoding information output from the decoding unit150, and output the received first decoding information and the received second decoding information through a provided display screen or the like. Preferably, the display unit160may output the decoding information having the same target information to be associated with each other. Through this, the user may easily check the first decoding information and the second decoding information related to each other.

A battery pack1according to another embodiment of the present disclosure may include the apparatus for providing battery information100according to an embodiment of the present disclosure.

FIGS.7and8are diagrams schematically showing a battery pack1including the apparatus for providing battery information100according to an embodiment of the present disclosure.

Specifically,FIG.7is a diagram schematically showing a battery pack1including one battery management system200, andFIG.8is a diagram schematically showing a battery pack1including a plurality of battery management systems200a,200b,200c.

Preferably, the battery management system200may be configured to output the battery information by using both the first communication protocol and the second communication protocol. Accordingly, the battery management system200may be connected to the first communication unit110and the second communication unit120of the apparatus for providing battery information100.

For example, if only the first communication protocol is available and the second communication protocol is not available, when the battery management system200is provided in the battery pack1, the battery management system200may be connected only to the first communication unit110.

In addition, although not shown inFIGS.7and8, the battery pack1according to the present disclosure may include at least one battery cell. In addition, the battery pack1may further include electrical equipment (a relay, a fuse, etc.) and a case.

An energy storage system (ESS)2according to another embodiment of the present disclosure may include the apparatus for providing battery information100according to an embodiment of the present disclosure.

FIG.9is a diagram schematically showing an energy storage system2including the apparatus for providing battery information100according to an embodiment of the present disclosure.

Referring toFIG.9, the energy storage system2may include a plurality of battery racks300a,300b,300c, a plurality of battery management systems200a,200b,200c, and the apparatus for providing battery information100.

For example, the battery rack300may be a cell assembly in which one or more battery modules310are mounted on a predetermined frame structure. In addition, the battery management system200may be provided to each of the plurality of battery racks300a,300b,300c.

In addition, the plurality of battery management systems200a,200b,200cmay be connected to the apparatus for providing battery information100. However, it should be noted that althoughFIG.9shows an example in which the battery management system200and the apparatus for providing battery information100are connected by wire, the battery management system200and the apparatus for providing battery information100may be connected through wireless communication.

The apparatus for providing battery information100may be configured to communicate with the battery management system200provided in the battery rack300by using the first communication unit110and the second communication unit120.

Therefore, there is an advantage in that information related to the battery rack300may be efficiently communicated by using a plurality of communication protocols.

FIG.10is a diagram schematically showing a method for providing battery information according to another embodiment of the present disclosure.

Here, the method for providing battery information may be performed by the apparatus for providing battery information100.

Hereinafter, it should be noted that contents overlapping with the above description will be briefly described.

Referring toFIG.10, the method for providing battery information according to another embodiment of the present disclosure includes a first receiving step (S100), a second receiving step (S200), a data conversion step (S300), and a data output step (S400).

The first receiving step (S100) is a step of receiving first battery information related to a battery from the battery management system200by using a first communication protocol, and may be performed by the first communication unit110.

The second receiving step (S200) is a step of receiving second battery information related to the battery and different from the first battery information from the battery management system200by using a second communication protocol different from the first communication protocol, and may be performed by the second communication unit120.

In addition, the second receiving step (S200) is a step in parallel with the first receiving step (S100). That is, the second receiving step S200may be performed at the same time as the first receiving step S100or may be performed at different time points.

The data conversion step (S300) is a step of converting the first battery information into a predetermined data structure to obtain first conversion information and converting the second battery information into the predetermined data structure to obtain second conversion information, and may be performed by the data conversion unit130.

Referring toFIG.4, the data conversion unit130may be connected to the first communication unit110and the second communication unit120. The data conversion unit130may receive the first battery information from the first communication unit110and receive the second battery information from the second communication unit120.
