Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

FIG.1is a diagram schematically showing an apparatus for supplying emergency power100according to an embodiment of the present disclosure.

Referring toFIG.1, the apparatus for supplying emergency power100according to an embodiment of the present disclosure may include a protection circuit unit110, a bypass unit120, and a control unit130.

First, the protection circuit unit110may be connected to a battery10.

Here, the battery10includes a negative electrode terminal and a positive electrode terminal, and may refer to one independent cell that can be physically separated. For example, one pouch-type lithium polymer cell may be regarded as a battery cell. In addition, the battery10may refer to a battery module in which one or more battery cells are connected in series and/or in parallel. Hereinafter, for convenience of description, it will be described that the battery10refers to one independent battery cell.

The protection circuit unit110may be configured to limit an available voltage range of the battery10.

That is, the protection circuit unit110may prevent the battery10from being overcharged or overdischarged by limiting the available voltage range of the battery10.

For example, it is assumed that the protection circuit unit110is connected to a 4.5 [V] battery10. The protection circuit unit110may be configured to limit the available voltage range to 2.7 [V] or more and 4 [V] or less in order to prevent the battery10from being overcharged or overdischarged.

The bypass unit120may be connected in parallel to the protection circuit unit110.

Specifically, a connection relationship between the protection circuit unit110and the bypass unit120will be described with reference toFIG.2.

FIG.2is a diagram schematically showing a battery pack1including the apparatus for supplying emergency power100according to an embodiment of the present disclosure.

Referring toFIG.2, the protection circuit unit110may be electrically connected to both ends of the battery10. For example, one end of the protection circuit unit110may be connected to the positive electrode terminal of the battery10, and the other end of the protection circuit unit110may be connected to the negative electrode terminal of the battery10. That is, one end of the protection circuit unit110may be connected between the positive electrode terminal of the battery10and a positive electrode terminal P+ of the battery pack1, and the other end of the protection circuit unit110may be connected between the negative electrode terminal of the battery10and a negative electrode terminal P− of the battery pack1. In addition, one end of the bypass unit120may be connected to the negative electrode terminal of the battery10, and the other end of the bypass unit120may be connected to the negative electrode terminal P− of the battery pack1.

Here, a load may be connected to the positive electrode terminal P+ and the negative electrode terminal P− of the battery pack1. For example, the load may be a charging terminal capable of charging the battery10or a terminal for receiving power from the battery10.

In addition, the bypass unit120may be configured to form a bypass path of a current output from the battery10according to an operation state of a disposed switching element121.

Specifically, the bypass unit120may be configured to form the bypass path configured such that the current of the battery10bypasses the protection circuit unit110when the operation state of the switching element121is controlled to a turn-on state.

An exemplary configuration of the protection circuit unit110and the bypass unit120will be described with reference toFIG.3.

FIG.3is a diagram showing an exemplary configuration of the battery pack1including the apparatus for supplying emergency power100according to an embodiment of the present disclosure.

Referring toFIG.3, the bypass unit120may include a switching element121. One end of the switching element121may be connected to the negative electrode terminal of the battery10, and the other end may be configured to be connected to the negative electrode terminal P− of the battery pack1.

For example, in the embodiment ofFIG.3, if the bypass unit120is electrically connected, a bypass path for connecting the negative electrode terminal of the battery10and the negative electrode terminal P− of the battery pack1may be formed.

In addition, referring toFIG.3, the protection circuit unit110may include a plurality of resistors R1, R2, R3, a capacitor C, an ICT111, and a switching unit112. By the configuration of the protection circuit unit110, the available voltage range of the battery10may be limited. The control unit130may be configured to electrically connect the bypass path formed by the bypass unit120by controlling the operation state of the switching element121to a turn-on state.

Specifically, the control unit130may be configured to control the operation state of the switching element121to a turn-on state or a turn-off state. If the control unit130controls the operation state of the switching element121to a turn-on state, the bypass path formed by the bypass unit120may be electrically connected. In this case, the current output from the battery10may flow through the bypass path without passing through the protection circuit unit110.

For example, in the embodiment ofFIG.3, the switching element121may employ a metal-oxide semiconductor field effect transistor (MOSFET). The switching element121may include a drain terminal D, a source terminal S, and a gate terminal G. The control unit130may be electrically connected to the gate terminal G of the switching element121and output a control signal to the gate terminal G. According to the control signal output by the control unit130, the operation state of the switching element121may be controlled to a turn-on state or a turn-off state.

The apparatus for supplying emergency power100according to an embodiment of the present disclosure has an advantage of controlling the current output from the battery10to flow through the bypass unit120or the protection circuit unit110by controlling the operation state of the switching element121provided in the bypass unit120.

Meanwhile, the control unit130provided to the apparatus for supplying emergency power100may 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 control 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 control unit130. The memory may be located inside or out of the control unit130and may be connected to the control unit130by various well-known means.

In addition, the apparatus for supplying emergency power100according to an embodiment of the present disclosure may further include a storage unit (not shown). The storage unit may store programs, data and the like required for the control unit130to manage the switching element121. That is, the storage unit may store data necessary for operation and function of each component of the apparatus for supplying emergency power100, data generated in the process of performing the operation or function, or the like. The storage unit is 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 unit may store program codes in which processes executable by the control unit130are defined.

Preferably, the control unit130may be configured to release the limit on the available voltage range by electrically connecting the bypass path.

FIG.4is a diagram schematically showing a voltage range of a battery10connected to the apparatus for supplying emergency power100according to an embodiment of the present disclosure.

For example, the battery10of the embodiment ofFIG.4is an example to which a 4.5 [V] pouch-type battery cell is applied.

In the embodiment ofFIG.4, the available voltage range of the battery10may be limited to 2.7 [V] or more and 4 [V] or less. Since the degradation rate of the battery10may be generally increased if the voltage of the battery10is less than 2.7 [V] or more than 4 [V], the limited available voltage range may be a voltage range arbitrarily set to prevent degradation of the battery10. However, it should be noted that the available voltage range of the battery10may be set differently from the range shown inFIG.4and the available voltage range may not be limitedly interpreted by the numerical values shown in the drawings and the embodiments of the present disclosure.

If the control unit130controls the operation state of the switching element121provided in the bypass unit120to a turn-on state, the bypass path formed by the bypass unit120may be electrically connected. In this case, since the current output from the battery10does not pass through the protection circuit unit110, the voltage range limited by the protection circuit unit110may be released.

For example, in the embodiment ofFIG.4, if the control unit130electrically connects the bypass path, the limit on the voltage range of 0 [V] or more and 2.7 [V] or less and the voltage range of more than 4 [V] may be released.

Since the available voltage range of the battery10is extended in this way, the battery10may be used for a long time.

Preferably, the control unit130may be configured to release the limit on a low-voltage range of the voltage range limited by the protection circuit unit110by electrically connecting the bypass path.

A case where the battery10is provided in a portable terminal will be described as an example. In a situation where the voltage of the battery10is close to a lower limit of the available voltage range so that the remaining amount of the battery10is short and the battery10is not being charged, there may occur a case in which the portable terminal needs to be used urgently. For example, this may be a case where it is necessary to turn on the flash of the portable terminal in a dark space or a case where an emergency call is in progress.

As another example, a case where the battery10is provided in a vehicle will be described as an example. When a vehicle is running, even if the voltage of the battery10reaches the lower limit of the available voltage range, there may be a case where the battery10must be continuously operated to supply an emergency power for the safety of a driver.

In the case where the battery10should be urgently used even if the battery10is degraded rapidly as in the above exemplary examples, the control unit130may electrically connect the bypass path in order to release the limit on the available voltage range of the battery10. In addition, since the available voltage range of the battery10is extended, the battery10may be operated longer.

Accordingly, when an emergency situation occurs, the apparatus for supplying emergency power100according to an embodiment of the present disclosure may release the limit on the available voltage range of the battery10by electrically connecting the bypass path by the bypass unit120. Therefore, in an emergency situation, the operating time of the battery10may be increased, so the user has an advantage of taking appropriate measures for the emergency situation by using the emergency power supplied by the battery10.

Hereinafter, each embodiment in which the control unit130controls the operation state of the switching element121provided in the bypass unit120to a turn-on state will be described.

First, the control unit130may be configured to control the operation state of the switching element121to a turn-on state if an emergency power supply request is input.

For example, the control unit130may be configured to communicate with the outside. If the control unit130receives an emergency power supply request from the outside, the control unit130may control the operation state of the switching element121to a turn-on state. In this case, the available voltage range of the battery10is extended so that the battery10may be continuously discharged. Therefore, the emergency power may be supplied to the load.

In another embodiment, the control unit130may be configured to control the operation state of the switching element121to a turn-on state during a preset initial run time.

Specifically, the control unit130may count the preset initial run time from a time point when the battery10starts operating. That is, when the battery10starts operating, the control unit130may control the operation state of the switching element121to a turn-on state during the preset initial run time, thereby releasing the voltage range limited by the protection circuit unit110.

Here, the preset initial run time may be stored in advance in the control unit130or the storage unit.

FIG.5is a diagram schematically showing an example of an abnormal behavior of the battery10.

For example, in the embodiment ofFIG.5, during the initial run time of the battery10, the voltage of the battery10may be abnormally and temporarily decreased.

Here, the initial run time may be set to correspond to a maximum capacity of the battery10. That is, as the maximum capacity [mAh] of the battery10is greater, the initial run time may be set longer. For example, in the embodiment ofFIG.5, the initial run time may be set to 10 seconds.

Since the battery10has both physical and chemical characteristics, there may be a case where the voltage of the battery10is abnormally decreased due to external factors when the battery10starts operating. For example, when the battery10starts operating, if the temperature of the battery10is very low or very high to be out of a reference temperature range, the voltage of the battery10may temporarily decrease. As another example, when the battery10starts operating, a case where the voltage of the battery10temporarily decreases due to degradation of the battery10may occur.

As in the embodiment ofFIG.5, when the voltage of the battery10is abnormally decreased below the available voltage range, if the protection circuit unit110is operated, the connection between the battery10and the load may be immediately cut off. That is, there may be a case where the connection between the battery10and the load is unexpectedly cut off due to an abnormal behavior of the battery10.

The control unit130may control the operation state of the switching element121of the bypass unit120to a turn-on state during the initial run time in order to cope with an abnormal behavior of the battery10. Accordingly, in the embodiment ofFIG.5, even if the voltage of the battery10reaches 2.7 [V] within the initial run time, the connection between the battery10and the load may not be cut off. In addition, after the preset initial run time, the control unit130may control the operation state of the switching element121of the bypass unit120to a turn-off state so that the protection circuit unit110operates.

Since the apparatus for supplying emergency power100according to an embodiment of the present disclosure prevents the protection circuit unit110from operating during the preset initial run time, there is an advantage of preventing the connection between the battery10and the load from being unexpectedly released due to an abnormal behavior of the battery10when the battery10starts operating.

Hereinafter, still another embodiment in which the control unit130controls the operation state of the switching element121will be described.

First, referring toFIG.1, the apparatus for supplying emergency power100according to an embodiment of the present disclosure may further include a measuring unit140configured to measure a voltage of the battery10.

For example, in the embodiment ofFIG.2, the measuring unit140may be electrically connected directly to both ends of the battery10. The measuring unit140may measure the voltage of the battery10by measuring a positive electrode voltage and a negative electrode voltage of the battery10and calculating a difference between the measured positive and negative electrode voltages.

In addition, the measuring unit140may transmit the measured voltage of the battery10to the control unit130.

The control unit130may be configured to measure a discharge time during which the battery10is continuously discharged.

For example, if charging and discharging of the battery10are alternately performed, the control unit130may measure a discharge time during which the battery10is continuously discharged. That is, the control unit130may be configured to measure a discharge time during which the battery10is continuously discharged without measuring the total time that the battery10is discharged.

The control unit130may be configured to control the operation state of the switching element121to a turn-on state if at least one of the measured discharge time and the measured voltage satisfies a predetermined condition.

That is, based on at least one of the measured discharge time and the voltage measured by the measuring unit140, the control unit130may determine whether there occurs an emergency situation in which an emergency power must be supplied. In addition, if it is determined that an emergency situation occurs, the control unit130may supply an emergency power to the load by controlling the operation state of the switching element121provided in the bypass unit120to a turn-on state.

Therefore, the apparatus for supplying emergency power100according to an embodiment of the present disclosure may determine whether an emergency situation occurs based on at least one of the voltage and the discharge time of the battery10, even if an emergency power supply request is not input from the outside. In addition, if it is determined that an emergency situation occurs, the apparatus for supplying emergency power100may electrically connect the bypass path to supply an emergency power to the load. Therefore, even when the user cannot request emergency power supply or the emergency power supply request is not normally transmitted to the control unit130, the apparatus for supplying emergency power100has an advantage of determining whether an emergency situation occurs and supplying an emergency power.

Preferably, the control unit130may be configured to measure the discharge time while the measured voltage is included in a preset low-voltage range.

Specifically, the control unit130may measure the discharge time only when the voltage of the battery10received from the measuring unit140is included in the preset low-voltage range.

Here, the preset low-voltage range may be stored in advance in the control unit130or the storage unit.

FIG.6is a diagram showing an example in which the apparatus for supplying emergency power100according to an embodiment of the present disclosure releases the limit on the available voltage range of the battery10.

For example, in the embodiment ofFIG.6, it is assumed that the battery10is continuously discharged from 0 second. In addition, it is assumed that the preset low-voltage range is 2.7 [V] or more and 2.8 [V] or less. The control unit130may measure the discharge time of the battery10from a time point t2 when the voltage of the battery10received from the measuring unit140is included in the preset low-voltage range.

In addition, the control unit130may be configured to control the operation state of the switching element121to a turn-on state if the measured discharge time is equal to or greater than a reference time.

For example, in the embodiment ofFIG.6, if the discharge time of the battery10measured from the time point t2 increases over the reference time, the control unit130may control the operation state of the switching element121to a turn-on state. That is, the control unit130may extend the available voltage range (2.7 [V] or more and 4 [V] or less) to 0 [V] or more and 4 [V] or less by controlling the operation state of the switching element121to a turn-on state at a time point t3.

Specifically, while the battery10is being continuously discharged, the control unit130may determine that an emergency situation occurs, if the time during which the voltage of the battery10belongs to the preset low-voltage range is greater than or equal to the reference time. For example, in a situation where the remaining amount of the battery10is low and the battery10cannot be charged, if the battery10must be continuously used, this situation may correspond to above case.

Therefore, the apparatus for supplying emergency power100according to an embodiment of the present disclosure has an advantage of reducing the hassle of requiring a user to directly request the supply of an emergency power by autonomously determining whether an emergency situation occurs. In addition, since an emergency power is supplied by the determination of the control unit130, there is an advantage in that an accident that may occur due to unexpected disconnection between the battery10and the load may be prevented in advance.

The control unit130may be configured to control the operation state of the switching element121to a turn-on state and then control the operation state of the switching element121according to the charge start voltage of the battery10measured by the measuring unit140when the battery10starts being charged.

Specifically, the measuring unit140may measure the charge start voltage of the battery10when the battery10starts being charged, after the operation state of the switching element121is controlled to a turn-on state.

In addition, the control unit130may control the operation state of the switching element121according to whether the charge start voltage of the battery10is included in the preset low-voltage range.

For example, the control unit130may be configured to control the operation state of the switching element121to a turn-off state if the charge start voltage is included in the preset low-voltage range. Conversely, the control unit130may be configured to control the operation state of the switching element121to a turn-on state if the charge start voltage is lower than the lower limit of the preset low-voltage range.

That is, the control unit130may release or block the bypass path formed by the bypass unit120according to the charge start voltage of the battery10.

For example, if the operation state of the switching element121is controlled to a turn-on state to form a bypass path by the bypass unit120, the battery10may supply an emergency power. In this process, if the voltage of the battery10is lowered to less than the preset low-voltage range, the voltage of the battery10may be less than the preset low-voltage range even when the battery10starts being charged. In this case, if the control unit130switches the operation state of the switching element121to a turn-off state, the protection circuit unit110may be operated to release the connection between the battery10and the load. That is, although the battery10starts being charged, the voltage of the battery10that has already supplied an emergency power may not be included in the available voltage range. Therefore, the control unit130does not control the operation state of the switching element121to a turn-off state only due to the fact that the battery10starts being charged, but may control the operation state of the switching element121in consideration of the charge start voltage of the battery10.

Preferably, after the battery10starts being charged, if the voltage of the battery10is included in the preset low-voltage range, the control unit130may control the operation state of the switching element121to a turn-off state so that the protection circuit unit110operates.

For example, in the embodiment ofFIG.6, it is assumed that the operation state of the switching element121is controlled to a turn-on state at the time point t3 so that the available voltage range is extended to 0 [V] or less and 4 [V] or more. In addition, it is assumed that the voltage of the battery10is decreased below the lower limit (2.7 [V]) of the preset low-voltage range after the time point t3. After that, even if the battery10is charged, the voltage of the battery10may be less than 2.7 [V]. Therefore, if the voltage of the battery10is included in the preset low-voltage range (2.7 [V] or more and 2.8 [V] or less), the control unit130may control the operation state of the switching element121to a turn-off state to block the bypass path formed by the bypass unit120and to operate the protection circuit unit110.

More preferably, the control unit130may be configured to control the operation state of the switching element121to a turn-on state in consideration of not only the voltage and the discharge time of the battery10but also a current of the battery10.

First, the measuring unit140may be configured to further measure the current of the battery10.

For example, in the embodiment ofFIG.2, the measuring unit140may be connected to a current measuring element A for measuring the current of the battery10. Here, the current measuring element A may be an ampere meter and/or a sense resistor.

The measuring unit140may transmit the measured current of the battery10to the control unit130, and the control unit130may receive the current of the battery10from the measuring unit140together with the voltage of the battery10.

In addition, the control unit130may be configured to measure the discharge time while the measured current is being included in a preset low-current range and the measured voltage is being included in the preset low-voltage range.

Here, the preset low-current range may be stored in advance in the control unit130or the storage unit.

Specifically, the control unit130may measure the discharge time during which the battery10is continuously discharged, only when the voltage of the battery10is included in the preset low-voltage range and the current of the battery10is included in the preset low-current range. That is, the control unit130may measure the discharge time while the battery10is being operated in a low power mode.

The control unit130may be configured to control the operation state of the switching element121to a turn-on state if the measured discharge time is greater than or equal to the reference time.

For example, if the battery10is not charged and is used over the reference time in a low power mode, the control unit130may determine that it is an emergency situation requiring urgent use of the battery10. In this case, the control unit130may be configured to supply an emergency power to the load by controlling the operation state of the switching element121to a turn-on state.

FIG.7is a diagram showing an exemplary configuration of a battery pack1including an apparatus for supplying emergency power100according to another embodiment of the present disclosure.FIG.8is a diagram showing an exemplary configuration of a battery pack1including an apparatus for supplying emergency power100according to still another embodiment of the present disclosure.

The protection circuit unit110may include a plurality of unit protection circuit units110configured to limit the available voltage range of the battery10by section.

For example, referring toFIGS.7and8, the apparatus for supplying emergency power100may include a first unit protection circuit unit110aand a second unit protection circuit unit110b. However, it should be noted that the number of the plurality of unit protection circuit units110is not limited to the embodiment illustrated inFIGS.7and8.

In addition, the bypass unit120may include a plurality of unit bypass units120configured to be connected in parallel to at least one of the plurality of unit protection circuit units110.

For example,FIG.7is an embodiment in which a first unit bypass unit120aand a second unit bypass unit120bare included in the apparatus for supplying emergency power100. Specifically, the first unit bypass unit120amay be connected in parallel to the first unit protection circuit unit110a, and the second unit bypass unit120bmay be connected in parallel to the second unit protection circuit unit110b.

As another example,FIG.8is an embodiment in which only the first unit bypass unit120ais included in the apparatus for supplying emergency power100. The first unit bypass unit120amay be connected in parallel to the first unit protection circuit unit110a. In this case, since the second unit bypass unit120bis not included, the current output from the battery10cannot bypass the second unit protection circuit unit110b. Therefore, the control unit130cannot release the limit on the voltage range according to the second unit protection circuit unit110b.

That is, the apparatus for supplying emergency power100shown inFIG.8includes only the first unit bypass unit120a. The apparatus for supplying emergency power100may extend the available voltage range to a first voltage range limited by the first unit protection circuit unit110ain certain cases, but may be configured to always operate the second unit protection circuit unit110bin order to prevent serious degradation of the battery10.

Preferably, voltage ranges of the battery10limited by the plurality of unit protection circuit units110may be different from each other. More preferably, the plurality of unit protection circuit units110may be configured to limit a voltage range closer to the available voltage range of the battery10as being provided closer to the electrode terminal of the battery pack1.

FIG.9is a diagram showing another example in which the apparatus for supplying emergency power100according to an embodiment of the present disclosure releases the limit on the available voltage range of the battery10.

For example, in the embodiment ofFIG.9, the limited first voltage range is a range of 2.5 [V] or more and less than 2.7 [V], and more than 4 [V] and 4.2 [V] or less, which is the voltage range limited by the first unit protection circuit unit110a. The limited second voltage range is a range of less than 2.5 [V] and more than 4.2 [V], which is the voltage range limited by the second unit protection circuit unit110b.

Therefore, by including the plurality of unit protection circuit units110, the apparatus for supplying emergency power100according to another embodiment of the present disclosure has an advantage of limiting the voltage range of the battery10in more detail.

Preferably, the control unit130may be configured to select a unit protection circuit unit110whose limited voltage section is closest to a present voltage of the battery10among the plurality of unit protection circuit units110.

In addition, the control unit130may be configured to control the operation state of the switching element121disposed in the unit bypass unit120corresponding to the selected unit protection circuit unit110to a turn-on state.

For example, in the embodiment ofFIG.9, the control unit130may select the first unit protection circuit unit110athat limits the first voltage range.

It is assumed that the voltage of the battery10belongs to the preset low-voltage range but the control unit130controls the operation state of the switching element121disposed in the second unit bypass unit120bto a turn-on state. In this case, since the first voltage range is still limited, there may be a problem in that an emergency power is not supplied to the load regardless that the limit of the second voltage range is released.

Therefore, the control unit130may release the limit on the voltage range closest to the present voltage of the battery10, so that an emergency power may be smoothly supplied.

The apparatus for supplying emergency power100according to the present disclosure may be applied to a BMS (Battery Management System). That is, the BMS according to the present disclosure may include the apparatus for supplying emergency power100described above. In this configuration, at least some of components of the apparatus for supplying emergency power100may be implemented by supplementing or adding functions of components included in a conventional BMS. For example, the protection circuit unit110, the bypass unit120, the measuring unit140and the control unit130of the apparatus for supplying emergency power100may be implemented as components of the BMS.

In addition, the apparatus for supplying emergency power100according to the present disclosure may be provided to a battery pack1. That is, the battery pack1according to the present disclosure may include the apparatus for supplying emergency power100and at least one battery cell. In addition, the battery pack1may further include electrical equipment (a relay, a fuse, etc.), and a case.

The embodiments of the present disclosure described above may not be implemented only through an apparatus and method, but may be implemented through a program that realizes a function corresponding to the configuration of the embodiments of the present disclosure or a recording medium on which the program is recorded. The program or recording medium may be easily implemented by those skilled in the art from the above description of the embodiments.
