In the tube joining device described in Patent Document 1, the "charge required" lamp lights up when the remaining battery level is low. However, since a large amount of electric power is required to blow the tube and the charging current of the battery is small, the tube joining device cannot be used for a while after the start of charging.

For example, suppose that when the tube joining device is taken out in an attempt to join the tubes, the "charge required" lamp is lit. Even if you notice it and start charging immediately, it takes about 23 hours, for example, for the built-in battery to be fully charged.

Further, the conventional tube joining device continues to charge at a low rate by continuously passing a minute current through the battery as long as it is being charged even after it is fully charged. Therefore, if charging is continued without noticing that the battery is fully charged, the battery may be deteriorated.

The charge control device 100 includes a battery 81, an AC adapter 82, a charging unit 83, a current detection unit 84, and a control unit 90. A temperature sensor 11e is attached to the battery 81 to detect the temperature of the battery 81. A diode 85 is provided between the battery 81 and the charging unit 83 to prevent backflow of current from the battery 81 to the charging unit 83.

It is equipped with a RAM (not shown).

The AC adapter 82 is connected to a commercial power source and converts the AC voltage of the commercial power source into a desired DC voltage (AC adapter voltage). The charging unit 83 charges the battery 81 using the DC voltage (AC adapter voltage) output by the AC adapter 82. The current detection unit 84 detects the charging current of the battery 81.

The control unit 90 uses the temperature of the battery 81 detected by the temperature sensor 11e, the voltage of the battery 81, and the charging current detected by the current detection unit 84 to instruct the charging unit 83 to turn on / off charging, or to perform a charging mode. Or instruct. Further, the control unit 90 detects the connection of the AC adapter 82 and instructs ON / OFF of the voltage supply from the AC adapter 82 to the charging unit 83.

<Operation of charge control device>
Next, the operation of the charge control device and the charge control method according to the present embodiment will be described with reference to the flowcharts of FIGS. 6 to 10. The flowcharts of FIGS. 6 to 10 are executed by the CPU 95 of the control unit 90.

The CPU 95 detects that the AC adapter 82 is connected to a commercial power outlet (S1000). This detection is performed depending on whether or not the DC voltage (AC adapter voltage) output by the AC adapter 82 is input to the tube joining device 1.

The CPU 95 determines whether or not the DC voltage (AC adapter voltage) input to the AC adapter 82 is within the normal range (S2000). If the input DC voltage (AC adapter voltage) is not in the normal range (S2000: NO), the process returns to the step of S1000.

If the input DC voltage (AC adapter voltage) is in the normal range (S2000: YES), the CPU 95 outputs a supply ON signal to the AC adapter 82 (S3000). As a result, the DC voltage (AC adapter voltage) output from the AC adapter 82 is supplied to the charging unit 83.

The CPU 95 outputs a charging ON signal to the charging unit 83 and supplies the power from the AC adapter 82 to the battery 81 (S4000).

The CPU 95 monitors the current during charging (S5000). If the charging current range of the battery 81 detected by the current detection unit 84 is normal (S5000: normal), the CPU 95 returns to the step of S4000 and continues charging. On the other hand, if the charging current range of the battery 81 detected by the current detecting unit 84 is abnormal (S5000: abnormal), the CPU 95 outputs a charging OFF signal to the charging unit 83 and outputs a supply OFF signal to the AC adapter 82. Then, the charging is turned off (S6000).

The above is the general operation of the charge control device 100. Next, the detailed operation of charging ON of S4000 will be described. FIG. 7 is a subroutine flowchart of “Charging ON” (S4000) of the operation flowchart shown in FIG.

The CPU 95 inputs the temperature (T) of the battery 81 detected by the temperature sensor 11e (S400). The CPU 95 determines whether or not the input temperature (T) is in the range of 0 ° C. or higher and 40 ° C. or lower (S410).

If the battery temperature (T) is not in the range of 0 ° C. or higher and 40 ° C. or lower (S410: NO), the CPU 95 returns to the process of the step of S400. On the other hand, if the battery temperature (T) is in the range of 0 ° C. or higher and 40 ° C. or lower (S410: YES), the CPU 95 measures the voltage (E) of the battery 81 (S420). The CPU 95 determines whether or not the measured voltage (E) is smaller than the predetermined voltage (α) (S430). If the voltage (E) is smaller than the predetermined voltage (α) (S430: YES), the CPU 95 sets the charging unit 83 to the initial charging mode (S440). In the initial charging mode, the charging unit 83 charges the battery 81 with the initial charging current.

On the other hand, if the voltage (E) of the CPU 95 is not smaller than the predetermined voltage (α) (S430: NO), the CPU 95 determines whether the measured voltage (E) is smaller than the predetermined voltage (β). Judge (S450). If the voltage (E) is smaller than the predetermined voltage (β) (S450: YES), the CPU 95 sets the charging unit 83 to the quick charging mode (S460). In the quick charge mode, the charging unit 83 charges the battery 81 with a quick charge current larger than the initial charge current.

On the other hand, if the voltage (E) of the CPU 95 is not smaller than the predetermined voltage (β) (S450: NO), the CPU 95 determines whether or not the measured voltage (E) is equal to or higher than the predetermined voltage (β). Judgment (S470). If the voltage (E) is equal to or higher than the predetermined voltage (β) (S470: YES), the CPU 95 sets the charging unit 83 to the supplementary charging mode (S480). In the supplementary charging mode, the charging unit 83 intermittently charges the battery 81 with a supplementary charging current smaller than the quick charging current.

If the voltage (E) is not equal to or higher than the predetermined voltage (β) (S470: NO), the CPU 95 returns to the process of the step of S400.

The magnitude relationship between the voltages α and β is α <β. Therefore, if the voltage of the battery 81 is lower than α at the time of charging, the battery 81 is not charged in the quick charge mode. First, charging is performed in the initial charging mode, and charging is performed in the quick charging mode from the time when the voltage of the battery 81 becomes α or higher.

As described above, when the temperature of the battery 81 is equal to or higher than a certain temperature, the CPU 95 instructs the charging unit 83 to use any of the initial charging mode, the quick charging mode, and the supplementary charging mode. Further, the CPU 95 sets the initial charge mode, the quick charge mode, and the supplementary charge mode depending on whether the voltage of the battery 81 is smaller than α, smaller than β, or greater than or equal to β.

Next, the processing of the “initial charging mode” of S440, the “quick charging mode” of S460, and the “supplementary charging mode” of S480 shown in FIG. 7 will be described in order.

FIG. 8 is a subroutine flowchart of the “initial charging mode” of the operation flowchart shown in FIG. 7.

When the processing of the initial charging mode is started, the charging unit 83 charges the battery 81 with the initial charging current (S441). The initial charging current is passed from the charging unit 83 to the battery 81 by applying a charging voltage higher than the battery voltage. The initial charging current is a current in milliamperes, and is a current such that the voltage of the battery 81 gradually increases.

The CPU 95 determines whether or not the temperature (T) of the battery 81 is within a certain range (S442). The term “within a certain range” is, for example, a temperature range higher than 0 ° C. and lower than 60 ° C. Next, the CPU 95 determines whether or not the charging current (I) of the battery 81 is within a certain range (S443). The term "within a certain range" is, for example, a current range larger than 40 mA and smaller than 110 mA. Further, the CPU 95 determines whether or not the elapsed charging time (t) is smaller than the A minute (S444). Further, the CPU 95 determines whether or not the voltage (E) of the battery 81 is equal to or higher than the predetermined voltage (α) (S445).

In the CPU 95, the temperature (T) of the battery 81 is within a certain range (S442: YES), the charging current (I) of the battery 81 is within a certain range (S443: YES), and the elapsed charging time (t) is A. If it is less than a minute (S444: YES) and the voltage (E) of the battery 81 is less than a predetermined voltage (α) (S445: NO), the initial charge mode is continued.

If the temperature (T) of the battery 81 is not within a certain range (S442: NO), the CPU 95 stops the initial charging (S446) and returns to the process of S400 in the flowchart of FIG.

The CPU 95 determines whether the charging current (I) of the battery 81 is within a certain range (S443: NO) or the elapsed charging time (t) reaches the A minute (S444: NO). The initial charge is stopped (S447).

When the voltage (E) of the battery 81 becomes equal to or higher than the predetermined voltage (α) (S445: YES), the CPU 95 returns to the flowchart of FIG. 7 and instructs the charging unit 83 of the quick charging mode.

FIG. 9 is a subroutine flowchart of the “quick charging mode” of the operation flowchart shown in FIG. 7.

When the process of the quick charge mode is started, the charging unit 83 charges the battery 81 with the quick charge current (S461). The rapid charging current is passed from the charging unit 83 to the battery 81 by applying a charging voltage higher than the battery voltage. The quick charge current is a current in amperes that is larger than the initial charge current, and is a current large enough to rapidly increase the voltage of the battery 81.

The CPU 95 determines whether or not the temperature (T) of the battery 81 is within a certain range (S462). The term “within a certain range” is, for example, a temperature range higher than 0 ° C. and lower than 60 ° C. Next, the CPU 95 determines whether or not the charging current (I) of the battery 81 is within a certain range (S463). The term "within a certain range" is, for example, a current range larger than 0.8 A and smaller than 1.6 A. Further, the CPU 95 determines whether or not the voltage (E) of the battery 81 is smaller than γ (S464). The voltage value of γ is the limit value of the charging voltage of the battery 81. Further, the CPU 95 determines whether or not the elapsed charging time (t) is smaller than the B minute (S465). Further, the CPU 95 calculates the voltage change rate ΔV of the battery 81 and determines whether or not the voltage change rate ΔV is equal to or higher than a certain value (S466).

In the CPU 95, the temperature (T) of the battery 81 is within a certain range (S462: YES), the charging current (I) of the battery 81 is within a certain range (S463: YES), and the voltage (E) of the battery 81 is set. If it is smaller than γ (S464: YES), the elapsed charging time (t) is smaller than B minutes (S465: YES), and the voltage change rate ΔV of the battery 81 is equal to or higher than a certain value (S466: YES), quick charging is performed. Is stopped (S467).

If the temperature (T) of the battery 81 is not within a certain range (S462: NO), the CPU 95 stops the initial charging (S468) and returns to the process of S400 in the flowchart of FIG.

The CPU 95 determines whether the charging current (I) of the battery 81 is within a certain range (S463: NO), whether the voltage (E) of the battery 81 is γ or more (S464: NO), and the elapsed charging time (t). When either the B minute is reached (S465: NO), the initial charging is stopped (S469).

If the voltage change rate ΔV of the battery 81 is less than a certain value (S466: NO), the CPU 95 continues the quick charge mode.

FIG. 10 is a subroutine flowchart of the “supplementary charging mode” of the operation flowchart shown in FIG. 7.

When the processing of the supplementary charging mode is started, the charging unit 83 charges the battery 81 with the supplementary charging current (S441). The supplementary charging current is passed from the charging unit 83 to the battery 81 by applying a charging voltage higher than the battery voltage. The supplementary charging current is a current in milliamperes like the initial charging current, and is a current sufficient to compensate for the natural discharge of the battery 81. The supplementary charging current is not continuously applied, but is intermittently applied for a very short time. The reason why the supplementary charging current is intermittently passed is to prevent deterioration of the battery 81.

The CPU 95 determines whether or not the temperature (T) of the battery 81 is within a certain range (S482). The term “within a certain range” is, for example, a temperature range higher than 0 ° C. and lower than 60 ° C. Next, the CPU 95 determines whether or not the charging current (I) of the battery 81 is within a certain range (S483). The term "within a certain range" is, for example, a current range larger than 40 mA and smaller than 110 mA. Further, the CPU 95 determines whether or not the voltage (E) of the battery 81 is smaller than γ (S484). The voltage value of γ is the limit value of the charging voltage of the battery 81. Further, the CPU 95 determines whether or not the supplementary charging is completed (S485).

In the CPU 95, the temperature (T) of the battery 81 is within a certain range (S482: YES), the charging current (I) of the battery 81 is within a certain range (S483: YES), and the voltage (E) of the battery 81 is set. If it is smaller than γ (S484: YES) and the supplementary charging is not completed (S485: YES), the supplementary charging mode is continued.

If the temperature (T) of the battery 81 is not within a certain range (S482: NO), the CPU 95 stops the supplementary charging (S486), and returns to the process of S400 in the flowchart of FIG.

When the charging current (I) of the battery 81 is not within a certain range (S483: NO) or the voltage (E) of the battery 81 is γ or more (S484: NO), the CPU 95 is used. , Stop the supplementary charging (S487).

If the supplementary charging is not completed (S485: NO), the CPU 95 continues the supplementary charging.

As described above, in the charge control device and the charge control method according to the present embodiment, first, if the battery 81 has a predetermined voltage or less, the battery 81 is initially charged, and the voltage of the battery 81 is a predetermined voltage. When the above is reached, charge the battery quickly. If the temperature, charging current, and voltage of the battery 81 deviate from a predetermined range during rapid charging, or if the rapid charging time exceeds the set time, rapid charging is terminated. Then, when the battery 81 is fully charged by the quick charge, it shifts to the supplementary charge and compensates for the natural discharge of the battery 81. In the supplementary charging, the supplementary charging current is intermittently supplied to the battery 81 after a certain period of time.

FIG. 10 is a diagram provided for explaining the operation of the charge control device and the charge control method according to the present embodiment.

As shown in the figure, the charging mode changes in the order of initial charging mode, quick charging mode, and supplementary charging mode. In the initial charge mode, the initial charge current is supplied to the battery 81, and the battery voltage of the battery 81 being charged is raised to a constant value (α (V)). Further, in the initial charge mode, the battery temperature rises slowly.

Next, in the quick charge mode, the quick charge current is supplied to the battery 81 to quickly charge the battery 81. In the quick charge mode, the battery temperature and the rate of change in battery temperature hardly change until just before reaching full charge. However, when the battery 81 reaches full charge, the battery voltage, the battery temperature, and the battery temperature change rate rise sharply.

Finally, in the supplementary charging mode, the supplementary charging current is intermittently supplied to the battery 81 to compensate for the spontaneous discharge of the battery 81. Specifically, the supplementary charging current is supplied every hour for about 2 minutes. Since the supplementary charging current is the one in which the minimum current for compensating for the natural discharge is intermittently supplied, there is little risk of deteriorating the battery 81 even if the battery 81 is still charged after rapid charging.

FIG. 11 is a temperature-voltage characteristic diagram of a battery charged by using the charge control method according to the present embodiment.

When the outside air temperature is 0 ° C., 25 ° C., or 40 ° C., the cell temperature rises sharply when the charge capacity of the battery 81 exceeds 100%, that is, when the battery 81 is fully charged. Further, the cell voltage of the battery 81 also rises sharply from the point where the battery 81 is fully charged, and then falls.

Therefore, in the present embodiment, whether or not the battery 81 is fully charged is detected by a decrease in the voltage of the battery 81 after the increase or an increase in the temperature of the battery 81.

As described above, according to the charge control device and the charge control method according to the present embodiment, after charging is started, if the remaining capacity of the battery 81 is small, initial charging is performed as necessary and then quick charging is performed. Therefore, the battery 81 can be fully charged in a short time. Further, since supplementary charging is performed intermittently after the battery 81 is fully charged, there is little risk of deterioration of the battery 81. As shown in FIG. 10, the magnitude relationship between the initial charge current, the quick charge current, and the supplementary charge current is such that the supplementary charge current value ≤ the initial charge current value <the quick charge current value.

When the charge control device and the charge control method according to the present embodiment are applied to the tube joining device 1, charging that conventionally took about 23 hours can be completed in about 1 hour. Further, even if the remaining capacity of the battery 81 is small and the lamp requiring charging is lit, the tubes T1 and T2 can be joined once by charging for about 15 minutes.

Although the charge control device and the charge control method according to the present invention have been described above through the embodiments, the present invention is not limited to the configuration described in the embodiments and is appropriately modified based on the description of the claims. It is possible.

For example, although the tube joining device 1 has been described as an example of the application target of the present invention, the application target of the present invention is not limited to the tube joining device 1.
