Description

Alarm setting device {Apparatus for setting a alarm}

The present invention relates to an alarm setting device, and more specifically, to an alarm setting device that operates the alarm unit by setting the elapsed time at the start of the timer unit and the alarm time of the alarm unit.

Recently, as the demand for portable electronic products such as laptops, video cameras, and portable phones has rapidly increased, and as the development of electric vehicles, energy storage batteries, robots, and satellites has begun, the need for high-performance batteries capable of repeated charging and discharging has increased. Research is actively underway.

Currently commercialized batteries include nickel cadmium batteries, nickel hydrogen batteries, nickel zinc batteries, and lithium batteries. Among these, lithium batteries have almost no memory effect compared to nickel-based batteries, so they can be freely charged and discharged, and have a very high self-discharge rate. It is attracting attention due to its low and high energy density.

Battery packs mounted on electric vehicles, etc. generally include at least one battery module. At this time, each battery module includes one or two or more battery cells connected in series.

The status of each battery module included in this battery pack is monitored by a battery management system (BMS). The battery management system outputs signals to control balancing operations, cooling operations, charging operations, discharging operations, etc., based on parameters (e.g., voltage, current, temperature) monitored from each battery module.

At this time, the battery management system outputs an alarm signal at a set alarm time using a timer unit and an alarm unit, thereby performing balancing operations, cooling operations, charging operations, and discharging operations at necessary times.

The alarm unit used in a conventional battery management system has the limitation of outputting an alarm signal only at an alarm time of a predetermined time unit. For example, when the predetermined time unit is 1 minute, the alarm unit outputs an alarm signal when the measurement time of the timer unit elapses 1 minute, 2 minutes, 3 minutes, etc. Accordingly, when the conventional battery management system uses an alarm unit that outputs an alarm signal only at the alarm time of a predetermined time unit, there is a problem in that the alarm signal cannot be output at the alarm time other than the preset time unit such as 1 minute and 30 seconds. there is.

Preferably, if it is determined that the requested alarm time is not the predetermined time unit, the setting unit may calculate a time difference that must be added for the requested alarm time to become the predetermined time unit.

Preferably, the setting unit can calculate the time difference using the following equation.

<Equation>

TG=TU-[RAT/TU]r

Here, TG is the time difference, TU is a predetermined time unit, RAT is the requested alarm time, and [RAT/TU]r is the remainder of dividing the requested alarm time by the predetermined time unit.

Preferably, if the setting unit determines that the requested alarm time is not the predetermined time unit, the setting unit may set the time difference to the elapsed time from the start of the measurement.

Preferably, when the setting unit determines that the requested alarm time is not the predetermined time unit, the setting unit calculates the number of units of the predetermined time unit included in the requested alarm time, and sets the alarm time using the number of units. You can set it.

Preferably, the setting unit can set the alarm time using the following equation.

<Equation>

AT=[RAT/TU]q+1

Here, AT is the alarm time, RAT is the requested alarm time, TU is a predetermined time unit, and [RAT/TU]q is the quotient of dividing the requested alarm time by the predetermined time unit.

Of course, the communication unit 42 may include another type of communication circuit that supports two-way communication with the external device 1 instead of the first and second photo relays 42a and 42b.

The DC-DC voltage converter 43 includes an enable terminal (EN), a power input terminal (IN), and a power output terminal (OUT). The power input terminal IN receives an input voltage from the battery module 20 or an external power source (eg, an auxiliary battery of an electric vehicle). That is, an input voltage from the battery module 20 or an external power source is applied to the power input terminal IN.

The control unit 44 may perform a setting operation for the battery module 20 based on the sensing signal from the sensing unit 41. For example, the control unit 44 may estimate the state-of-charge (SOC) of each battery cell based on the cell voltage and current measured by the sensing unit 41. As another example, when the state of charge of at least one battery cell is outside a predetermined range, the controller 44 may turn off the contactor 30 to block charging or discharging of the battery module 20.

The control unit 44 generates an alarm signal for the timing of performing the setting operation for the battery module 20 and the control operation of the sensing unit 41, communication unit 42, and DC-DC voltage converter 43.

Hereinafter, the alarm setting device 100 according to an embodiment of the present invention will be described.

Figure 3 is a timing chart for explaining the process of setting the alarm time by the setting unit 130 of the alarm setting device 100 according to an embodiment of the present invention when the requested alarm time is a predetermined time unit. 4 is a timing chart to explain the process by which the setting unit 130 of the alarm setting device 100 according to an embodiment of the present invention sets the alarm time when the requested alarm time is not a predetermined time unit.

Referring further to FIGS. 3 and 4 , the alarm setting device 100 includes a timer unit 110 to output an alarm signal to the battery management device 40 at the requested alarm time requested from the battery management device 40. It may include an alarm unit 120 and a setting unit 130.

The timer unit 110 can measure the elapsed time from the start of measurement. More specifically, when the measurement start signal is received from the setting unit 130, the timer unit 110 may measure the elapsed time from the measurement start point, which is when the measurement start signal is received.

The timer unit 110 may output the elapsed time measured from the start of measurement to the alarm unit 120 in real time.

The alarm unit 120 may check whether the alarm time of the predetermined unit time is the same as the elapsed time received from the timer unit 110, and output an alarm signal in response to the confirmation result.

Here, the alarm time of the predetermined unit time may be a time obtained by adding only the predetermined unit time. For example, if the predetermined unit time is “1 minute (60 seconds),” the alarm time is “1 minute”, “2 minutes”, “3 minutes”, etc. with the predetermined unit time “1 minute” added. It could be one of the times.

Additionally, the predetermined time unit may be a normal time unit or an arbitrary time unit. For example, the predetermined time unit may be a conventional time unit such as "1 minute (60 seconds)", "1 hour (60 minutes)", etc., or "25 seconds", "30 minutes", "2 hours", etc. It may be an arbitrary unit of time, such as:

Accordingly, the alarm unit 120 can output an alarm signal only at a time in which a predetermined unit time is added.

The alarm unit 120 may output an alarm signal when the alarm time and elapsed time of a predetermined unit time are the same. More specifically, the alarm unit 120 may output an alarm signal to the control unit 44 when the alarm time of the predetermined unit time set by the setting unit 130 and the elapsed time received from the timer unit 110 are the same. .

The setting unit 130 checks whether the requested alarm time is a predetermined time unit, calculates the time difference that must be added to make the requested alarm time a predetermined time unit in response to the confirmation result, and calculates the time difference between the requested alarm time and the time difference. You can use one or more of the following to set the alarm time and the elapsed time from the start of measurement.

Here, the requested alarm time may be the alarm time requested from the control unit 44.

The setting unit 130 may check whether the requested alarm time is a predetermined time unit based on the remainder of dividing the requested alarm time by the predetermined time unit.

The setting unit 130 determines that the request alarm time is a predetermined time unit if the remainder after dividing the request alarm time by the predetermined time unit is "0", and conversely, the remainder after dividing the request alarm time by the predetermined time unit is "0". "Otherwise, you can confirm that the requested alarm time is not a predetermined time unit.

For example, if the request alarm time requested from the control unit 44 is 100 seconds and the predetermined time unit is 60 seconds (1 minute), the setting unit 130 changes the requested alarm time of 100 seconds to the predetermined time unit of 60 seconds. You can check whether the remainder after division is “0”. The setting unit 130 may confirm that the requested alarm time of 100 seconds is not a predetermined time unit because the remainder after dividing the requested alarm time of 100 seconds by the predetermined time unit of 60 seconds is 40 seconds.

Afterwards, when it is confirmed that the requested alarm time is a predetermined time unit, the setting unit 130 does not calculate the above-described time difference, as shown in FIG. 3, but sets the request time at which the alarm is requested from the control unit 44 to the timer unit. It can be set as the elapsed time from the measurement start point of 110, and the corresponding requested alarm time can be set as the alarm time of the alarm unit 120.

For example, if the request alarm time requested from the control unit 44 is 60 seconds and the predetermined time unit is 60 seconds, the setting unit 130 determines that the requested alarm time is a predetermined time unit and The request time at which an alarm is requested can be set as the elapsed time from the measurement start point of the timer unit 110, and the requested alarm time of 60 seconds can be set as the alarm time of the alarm unit 120.

At this time, when the setting unit 130 sets the request time at which an alarm is requested from the control unit 44 to the elapsed time from the measurement start point of the timer unit 110, the elapsed time measured from the timer unit 110 is determined by the control unit 44. It may be equal to the actual time elapsed from the time the alarm was requested from (44).

Accordingly, the alarm unit 120 may output an alarm signal to the control unit 44 when the elapsed time measured by the timer unit 110 is equal to the set alarm time of 60 seconds.

Meanwhile, if it is confirmed that the requested alarm time is not a predetermined time unit, the setting unit 130 may calculate the time difference described above.

More specifically, the setting unit 130 may calculate the time difference that must be added for the request alarm time to become a predetermined time unit, rather than a predetermined time unit.

At this time, the setting unit 130 can calculate the time difference using Equation 1 below.

<Equation 1>

TG=TU-[RAT/TU]r

Here, TG is the time difference, TU is a predetermined time unit, RAT is the requested alarm time, and [RAT/TU]r is the remainder of dividing the requested alarm time by the predetermined time unit.

For example, if the requested alarm time requested from the control unit 44 is 100 seconds and the predetermined time unit is 60 seconds, the setting unit 130 changes the requested alarm time 100 seconds from the predetermined time unit 60 seconds to the predetermined time unit. The time difference can be calculated as 20 seconds by subtracting the remaining 40 seconds divided by 60 seconds.

Thereafter, if it is confirmed that the requested alarm time is not a predetermined time unit, the setting unit 130 may set the calculated time difference as the elapsed time from the start of measurement, as shown in FIG. 4.

As in the example described above, if the time difference is calculated to be 20 seconds, the setting unit 130 may set the elapsed time from the start of measurement to 20 seconds.

Accordingly, the elapsed time measured by the timer unit 110 at the start of measurement may already be 20 seconds.

Additionally, if it is confirmed that the requested alarm time is not a predetermined time unit, the setting unit 130 may calculate the number of units of the predetermined time unit included in the requested alarm time and set the alarm time using the number of units.

At this time, the setting unit 130 can set the alarm time using Equation 2 below.

<Equation 2>

AT=([RAT/TU]q+1)×TU

Here, AT is the alarm time, RAT is the requested alarm time, TU is a predetermined time unit, and [RAT/TU]q is the quotient of dividing the requested alarm time by the predetermined time unit.

For example, as shown in FIG. 4, when the requested alarm time requested from the control unit 44 is 100 seconds and the predetermined time unit is 60 seconds, the setting unit 130 sets the requested alarm time 100 seconds as the predetermined time. You can set the alarm time as 120 seconds, which is the quotient 1 divided by the unit of 60 seconds, multiplied by 1 plus 2, and the predetermined time unit of 60 seconds.

Here, the setting unit 130 sets the alarm time as a time exceeding the requested alarm time, but the elapsed time at the start of the measurement of the timer unit 110 is also set as the time elapsed by the time difference, so the notification unit 120 An alarm signal can be output according to the requested alarm time.

According to this configuration of the present invention, the alarm unit 120, which outputs an alarm signal only at the alarm time of a predetermined time unit, can be used to output an alarm signal at a requested alarm time rather than a predetermined time unit.

Hereinafter, the setting unit 130' according to another embodiment will be described.

Figure 5 is a timing chart to explain a process in which the setting unit 130' controls the timer unit 110 according to another embodiment.

Referring further to FIG. 5, the setting unit 130' according to another embodiment includes a timer unit 110 that checks whether the request alarm time is a predetermined time unit compared to the setting unit 130 according to one embodiment. The configuration for setting the elapsed time from the start of measurement and the configuration for setting the alarm time of the alarm unit 120 may be the same.

Unlike the setting unit 130 according to one embodiment, the setting unit 130' according to another embodiment is a timer so that the timer unit 110 remeasures the elapsed time after the alarm unit 120 outputs a notification signal. The unit 110 can be controlled and the elapsed time from the start of re-measurement of the timer unit 110 can be set to the time difference described above.

More specifically, when the alarm unit 120 outputs a notification signal, the setting unit 130' according to another embodiment outputs a remeasurement signal to the timer unit 110 to remeasure the elapsed time. can be controlled.

At this time, the setting unit 130' according to another embodiment may set the elapsed time from the start of measurement to the time difference described above. In addition, the setting unit 130' according to another embodiment calculates the number of units of a predetermined time unit included in the request alarm time in the same way as the setting unit 130 according to one embodiment, and uses the number of units to generate an alarm. You can set the time.

Accordingly, as shown in FIG. 5, the setting unit 130' according to another embodiment sends a notification signal when the requested alarm time is 100 seconds, the predetermined time unit is 60 seconds, and the calculated time difference is 20 seconds. By setting the elapsed time from the re-measurement start point of the timer unit 110 to the calculated time of 20 seconds at the output time, the alarm unit 120 can output an alarm signal every 100 seconds of the requested alarm time.

These setup units 130 and 130' are hardware-wise, including application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), and field programmable gates (FPGAs). It may be implemented using at least one of arrays, microprocessors, and other electrical units for performing functions. The setting units 130 and 130' may have a built-in memory.
