Abstract

PURPOSE:To enable clear presentation of a state of charge by varying a display level depending on condition of charging half or full according to an increase or decrease in the capacity of a battery. CONSTITUTION:When a battery 1 is charged, a control circuit 6 controls an oscillation circuit 9, a flash switching circuit 11 and a display driving circuit 7 to perform a display by flashing by a signal of a charging circuit 2. While the battery discharges, a discharge signal is outputted from a switch 3 and a display by flashing is performed likewise. A lighting only is performed when the battery is not in use without being charged. A flashing informs a user of the inputting or outputting of current in the battery. Upon the completion of charging, the control circuit 6 controls the oscillation circuit 9 and the display driving circuit 7 to stop the flashing. The total lighting is performed to inform the user of a full charging.

INDUSTRIAL APPLICATION FIELD 1 The present invention relates to a battery capacity display device that displays the status of a battery according to an increase or decrease in battery capacity. [Prior Art] Conventionally, as a battery capacity display VC device that displays the status according to the increase or decrease of battery capacity, there is one disclosed in Japanese Patent Application Laid-open No. 62-40029, which displays the maximum level of the current display. I am trying to make the part blink. [Problems to be Solved by the Invention] In the above-mentioned conventional technology, in order to clarify the boundary between display levels, the display section at the current maximum level is destroyed, and the display section at the intermediate level is When the level changes, when it exceeds that blinking level, that level lights up and the next level blinks, so you know that that level has been met, but at the final full charge (charging completion) it will remain blinking. ,
The problem is that it is difficult to tell whether the battery is in the middle of its level or fully charged. The present invention has been made in view of the above, and an object of the present invention is to provide a battery capacity display device that can tell whether the battery is currently in the middle of the display level or whether it is fully charged at that level.

Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a battery 1 is charged by a charging circuit 2 and discharged by energizing a load 4 (via a switch 3). Capacity detection circuit 5 detects the capacity of battery 1 and inputs the detected capacity to control circuit 6 which controls each block according to the detected capacity. The control circuit 6 controls the display drive circuit 7 and the capacitance detection circuit 5.
The display circuit 8 displays the capacitance detected by the display circuit 8. If the capacity (mode) requires blinking at that time, the oscillation circuit 9 is operated by the control circuit 6, and the display drive circuit 7 oscillates at a period determined by the oscillation cycle setting circuit 10 to cause the display to blink. In order to switch the oscillation part of the display drive circuit 7 according to the state, the control circuit 6 controls the blinking switching circuit 11 to switch the joint between the display drive circuit 7 and the oscillation circuit 9, and determine the blinking part of the display. Buzzer 1
2 notifies the completion of charging. While the battery 1 is being charged, a charging signal is output from the charging circuit 2 and input to the control circuit 6. The oscillation circuit 9
, the blinking switching circuit 11, and the display drive circuit 7 to perform blinking display. During discharging, a discharge signal is output from the switch 3, and the display blinks in the same way. Therefore, except during charging and discharging,
In other words, it does not charge and only lights up when not in use. Therefore, the blinking means that current is flowing in and out of the battery 1, which can be notified to the user. When charging is completed, a completion signal is output from the charging circuit 2 and input to the control circuit 6. This signal controls the oscillation circuit 9 and the display drive circuit 7, and the capacity display stops blinking and becomes fully lit. Fully lit means fully charged. A plurality of display sections 13 are provided as shown in pI2 diagram (d), and during charging, as the g amount of the battery 1 increases, the display sections 13 blink in the order of (b), (c), and (d) from FIG. 2 (a). is switched,
The lower display section lights up. In addition, in FIGS. 2(a) to 2(d), the portion surrounded by a broken line around the display section 13 indicates that it is blinking. Further, the energization display section 14 displays that the power is being energized. When the battery reaches less than 100%, the flashing parts are switched to higher rank one after another, and when fully charged, all lights are on as shown in FIG. 2(d). In other words, while it is blinking, it is within the range of the display level (for example, 20% or more and less than 40%), and when it reaches the highest level (for example, 40%), it lights up and the next higher level (for example, 40%) is displayed, indicating that the value must be exceeded. For example, 40% or more, 60%
(less than %) flashes. Blinking at each level represents less than the top value of that level, and solid light represents the top value. When fully charged, all the lights are on, and the energization display section 14 turns off,
This means that the charging current is controlled or cut to the terminal current, and a double display indicating that charging is complete is displayed. Figure 3(a)~
(d) shows the time of discharging, and conversely, the light blinks until the lowest value is reached at each level, and turns off at the lowest value. In this case, there is a time opening that is not in the -instantaneous region. Also, except when fully charged, the next blinking may begin when the highest value is reached. When charging is completed, this display eliminates the need for other display circuits and is effective. FIG. 4 shows another embodiment of the present invention, in which a numeral 15 representing the capacity of the battery 1 is displayed along with a display section 13 that can be turned off, turned on, and turned off. Alternatively, only the lighting may be synchronized without erasing the numbers, or only the numbers may be displayed. ,
Further, the display may be performed using a liquid crystal or a light emitting diode. Furthermore, the circuit of FIG. 1 may be implemented as a microcomputer. As shown in FIG. 5(a), the buzzer 12 will emit approximately 1
The cycle of 8 pulses per second and 3 seconds off is repeated, and at the point when the display changes, 2 pulses are notified once within the same pulse as shown in Figure 5 (b), and when it is less than 20%, As shown in Figure 5 (C), 3 pulses (about 0.5 seconds),
Repeat 0.5 seconds off. The repetition is performed, for example, 4 times, and if it becomes 20% or less, the sound is also sounded when the switch 3 is turned on and when the switch 3 is turned off. Depending on the application, the optimum number of pulses, pulse width, number of cycles, etc. are selected. In FIG. 1, depending on the difference between the capacitance level of the capacitance detection circuit 5 and a preset level, for example, a 5-step level, the control circuit 6 is connected to the oscillation circuit 9, the display drive circuit 7, the blinking switching circuit 11, and the oscillation cycle setting circuit. As shown in FIG. 6, the capacity can be known in more detail by controlling the display blinking cycle or blinking duty depending on which level is within the five levels, for example, as shown in FIG. Figure 6 shows 6
The blinking cycle can be changed from A to E as shown in Fig. 6(a), or blinking as shown in Fig. 6(b) to correspond to levels A to E when the percentage is 0% to less than 80%. The duty is changed like A-E. [Effect of the invention 1] Since the present invention is configured as described above, it is possible to know whether the display content is in the middle of the current display level or whether it is fully charged at that level.
Furthermore, there is no need for a separate path for displaying the completion of charging, and this has the effect that at each level, it can be determined whether it is in the middle of the level, the highest level, or the lowest level.
