FIG. 1 is a configuration diagram showing a charging battery life detecting device according to an embodiment of the present invention.

1, a charging battery life detecting apparatus 500 according to an exemplary embodiment of the present invention includes a battery management system (BMS) 400 that controls a state of a rechargeable battery cell BC, A plurality of detection modules 100 for detecting battery management information which are individual management information on a plurality of the battery packs in contact with each of the packs BP1 to BPn, A storage module (300) for storing the battery management information transmitted by the communication module (200) and battery processing information obtained by processing the battery management information, a battery management information And an analysis module 400 for analyzing the life of each rechargeable battery pack by processing information.

For example, the detection module 100 may include a plurality of detection sensors 110 connected to the battery management system (BMS) to detect the battery management information, (120) for generating digital data relating to the battery management information for each battery (BP).

The battery pack BP includes a plurality of rechargeable battery cells BC and a battery management system (BMS) connected to the battery cells BC to individually manage and control battery characteristics of the battery packs BP. Respectively.

For example, the battery pack BP includes a solar battery that converts solar energy into electrical energy using a solar condenser, discharges the charged electrical energy, and uses the solar battery as an energy source. At this time, the solar battery is composed of a plurality of solar cells, and the voltage, current, and charge state of each solar cell are controlled by the battery management system (BMS). Alternatively, the battery pack BP may include a lithium polymer battery pack having a plurality of lithium ion batteries.

The detection sensor 110 detects and collects the states of the battery cells BC disposed in the respective battery packs BP and disposed separately for each of the battery packs BP to detect battery management information . For example, the battery management information includes a voltage, a current, a temperature, and a charged gas remaining amount and components of each battery cell bc.

The data collection unit 120 converts the analog data related to the battery management information detected by the detection sensor 110 into digital data and converts the analog data into a form that can be processed by digital signal processing. For example, the data collecting unit 120 may include a detecting unit 121 connected to the detecting sensor 110 to detect an analog signal related to the battery management information, And an A / D converter 122 for converting the battery management information into a signal and a signal processor 123 for processing a digital signal related to the battery management information.

The communication module 200 may include at least one of a wired communication terminal and a wireless communication chip. The communication module 200 transmits the digital signal converted by the signal processing unit of the storage module 300 to the storage module 300 by the signal processing unit 123.

For example, the communication module 200 may include a network setting unit 210 for activating any one of a wired communication terminal and a wireless communication chip to set a communication unit, and a communication unit set by the network setting unit 210, And a transmitting unit 220 for transmitting digital data relating to battery management information.

The transmission unit 220 may include a local area network (LAN) terminal, a wireless LAN chip, a Bluetooth tooth chip, a 3G mobile communication chip, and a fourth generation (4G) And a mobile communication chip.

The storage module 300 stores digital data related to battery management information generated by the data collection unit 120 and battery processing information, which is secondary data generated by processing battery management information.

For example, the storage module 300 may include a data processor 310 for processing the digital data related to the battery management information to generate the battery processing information, a memory for storing the battery processing information and the battery management information in a data server A buffer memory 320 for temporarily storing data, a communication chip 330 for exchanging data with the outside, and a data server 340 for storing the battery processing information and the battery management information.

The data processor 310 processes battery management information transmitted through the communication tip 330 to generate additional information regarding the state of the battery pack BP. For example, the resistance or power of the battery may be generated as new management information based on the battery voltage or current, which is management information detected by the detection sensor 110, and may be stored as battery processing information.

Since the battery management information is transmitted at regular intervals, the management information and the processing information are periodically stored in the data server 340. At this time, since the battery management information is periodically transmitted from the data collection unit 120, the management information and the processing information are stored in the data server 340 in the same manner as the transmission period. If the data transmission period is extremely short or the capacity of the processing information is large, the transmission to the data server 340 may be delayed. At this time, the management information and the processing information may be temporarily stored in the buffer memory 320 before being stored in the data server 340. The buffer memory 320 may be formed of a DRAM or a flash memory device.

The data server 340 includes a master server 341 for storing the battery processing information and battery management information as digital data, and a slave server 342 for preliminarily storing the same digital data as the master server ) So that management information and processing information can be distributedly stored. Particularly, the data stored in the slave server 342 is configured as duplicate data of the data stored in the master server 341, thereby preventing the entire data from being lost due to an error of the mast server 341.

The communication chip 330 communicates with the communication module 300 and the analysis module 400 to be described later and saves the battery management information and the processing information in the data server 340 or extracts it from the data server 340 To the analysis module 400. It is obvious that the management information and the processing information data can be temporarily stored in the buffer memory 320 when a time delay occurs in the data signal transmitted to the analysis module 400.

The analysis module 400 extracts the battery management information and the battery processing information stored in the data server 340 and analyzes the life span of each battery pack BP.

For example, the analysis module 400 may include a data pager 410 for periodically calling and storing the battery management information and the battery processing information from the storage module 300, And a drive controller 430 for driving the data pager 410 and the life span analyzer 420. The life span analyzer 420 analyzes the life span of each battery pack BP and generates life span information of each battery pack BP.

The data pager 410 generates a paging signal for calling management information and processing information on the battery pack BP to be analyzed by the storage module 300 according to the analysis signal of the pseudo-type controller 430. [ The call signal is transmitted to the storage module 300 through the communication chip 330 through the wired / wireless communication means and the management data about the battery pack BP and the digital data about the processing information are transmitted from the data server 340 And is transmitted to the lifetime analyzer 420.

The life span analyzer 420 analyzes the called battery management information and processing information to calculate the remaining service life of the battery pack (BP). For example, the management information such as the effective voltage, the effective current, the charged state, the internal temperature, the cell balance value, the gas component and the remaining amount of each battery cell BC constituting the battery pack BP, The lifetime of the battery pack BP including a plurality of battery cells BC is predicted by using processing information such as cell power generated by processing a current and the number of times of charging and discharging. In particular, if the expected life is less than the reference value, the battery replacement signal is sent in an alarm form.

The drive controller 430 controls the battery pager 410 and the life span analyzer 420 to control the battery life span 500 using a control solution.

For example, the drive controller 430 is driven by an open application programming environment (" open API ") and is driven by an operating system independent OS solution.

Accordingly, the analysis module 400 is configured as a part of a control system driven by an operating system (OS) connected by an interface function of the open API, and is controlled by the operating system (OS) through the control solution Can be configured. Thus, if it can be connected to the open API through an interface function, it can be configured as a part of a system having various operating systems. Accordingly, the analysis module 400 may be configured as a sub-system independent of the operating system.

For example, the analysis module 400 may be part of a computer system connected by a wired network and driven by a Windows operating system, or may be part of a mobile system connected by a wireless network and driven by the Android operating system .

Accordingly, if necessary, the analysis module 400 may further include a display 440 controlled by the control solution and displaying the battery management information, the battery processing information, and the battery life information.
