Abstract

PURPOSE:To enable the residual life time to be sensually grasped, by arranging segments in such an order as placing the segment corresponding to the highest voltage at first and making the length of each segment to be different in accordance with the period of time required until the voltage drops to the appropriate level. CONSTITUTION:The voltage of a nickel-cadmium battery E used for a portable video tape recorder or the like is compared by means of a comparator COM with a reference voltage in an R-2R ladder circuit LAD controlled by a microcomputer MCO, and said voltage is displayed on a liquid crystal display part DIS. Also, the battery life time display region BLT is formed by the display segments Seg1-Seg7, and segments are arranged in such an order as placing the segment corresponding to higher voltage more right side, and the length of each segment is made to be different in accordance with the period of time required until the voltage of this segment drops down to the value corresponding to that of next segment. Consequently, the residual life time of a battery can be decided by the length of the display, and the exchange or the like of the battery can be effectively performed.

However, the magnitude of the urgency of the need for replacement, etc., in other words, the degree of urgency, could not be recognized1, so the display segment indicating that the need for replacement, etc. had arisen was not displayed. Even though I was actually able to continue video shooting and recording for about 2.3 minutes at one time, I ended up changing the panties according to the segment display and missed out on a scene that I could never film again. There is a risk that this will happen.

NiCd batteries used as a power source for voke pull video tape recorders, etc., have a temporal change in terminal voltage Ve, that is, a nearly constant discharge characteristic for the same load. Figure 1 is a characteristic diagram showing an example of the discharge characteristic. It is. As is clear from this characteristic diagram, if the NiCd battery is sufficiently charged, the terminal voltage Ve will be slightly higher than 1.20V.
Immediately after the discharge starts, the voltage becomes 1.20V. and,
The terminal voltage V e If maintains a value of 1.20V for 60 minutes. There is no need to replace the battery during this time. By the way, after 60 minutes, the terminal voltage V
e begins to decrease and drops to 1.175v in about 2 minutes.

The time required to drop from 1.175V to 1.15V is about 1 minute, and from 1.15V to 1.12V.
The time required for the terminal voltage Ve to drop to 5V is approximately a few seconds, and the rate at which the terminal voltage Ve decreases rapidly increases, and the rate at which the terminal voltage Ve decreases to 1.05V or less becomes extremely rapid, making it unusable.

When the maximum value is reached, the value returns to a predetermined initial value, and then increases by 1 to the maximum predetermined value, which is repeated at regular intervals. And the reference voltage Vref
is lower than the divided voltage VX, the output voltage Vcom of the comparator COM becomes "low", and the reference voltage V
When ref is higher than the divided voltage Vx, the output voltage Vc
om becomes "high". The larger the value of the divided voltage Vx is, the later the timing at which the output voltage Vcom of the comparator COM switches from "low" to "high" is delayed. However,
By detecting the timing of switching from "low" to "high", the divided voltage Vx and, by extension, the terminal voltage Ve of the battery E are detected.

The above segment Seg has a terminal voltage Ve of 12 which is a steady voltage.
Except for the segment Segl which is in the display state when it is at V, each segment has a length corresponding to the length of time during which the display state is maintained. That is, Seg2 enters the display state when the terminal voltage Ve of the battery E becomes lower than 12V, and this state continues until the terminal voltage Ve drops to 11.75V. Also, Sefmen) Seg
3 also enters the display state when the terminal voltage Ve becomes lower than 1.1.75V, and the terminal voltage Ve becomes 11.
.. This state continues until the voltage drops to 50V, and so on, each segment) Seg 2 to 7 maintains the display state when the voltage Ve at the end 7'' of the battery E is within the range corresponding to the segment. The time the display state is maintained varies depending on the segment Seg.Specifically, the time the segment Seg2 maintains the display state is 1L, 75V from the time when the terminal voltage Ve becomes lower than 12 OOV. The time to maintain the display state of segment Seg3 is longer than the time it takes to reach the point where the terminal voltage Ve changes from 11°75V to 11.50V.
It takes less time for the temperature to drop to . Furthermore, the time during which segment Seg4 remains in the display state is longer than the time during which segment Seg3 remains in the display state.
The time required to drop to 1.25V is shorter.

Similarly, the power of Seg5 is shorter than the time to maintain the display state of segment Seg4. In this way, the time for which the display state of segment Seg is maintained becomes shorter as one goes from segment Seg2 to Seg7. And that segment Seg2~7
has a length corresponding to the time the display state is maintained, such that the longer the time the display state is maintained, the longer the display state is maintained. In other words, each segment l- except Segl
S e g corresponds to the length of time required for the terminal voltage of battery E to change from the voltage corresponding to that segment to the voltage corresponding to the next segment. has been shortened in length.

Therefore, the magnitude of the distance from the segment () Seg currently in the display state to Seg 7 corresponding to the lowest voltage corresponds to the length of the remaining life of the pantry E. Therefore, the length of the remaining life of the battery E can be determined from the magnitude of the distance. Accordingly, it is possible to determine the degree of urgent need to replace or charge the battery.

(1) Learn the multiple display segments that correspond to each voltage and become displayed when the terminal voltage of the battery reaches the corresponding voltage, and move in a fixed direction from the one corresponding to the voltage to the one corresponding to the lower voltage. A number of display segments are arranged along the grid and correspond to a voltage below a certain low terminal voltage which at least causes the need for replacing or recharging the pantry, and from that corresponding voltage corresponds to the next display segment. A battery life display device characterized in that the length of the display segments in the arrangement direction varies depending on the length of time required for the terminal voltage of the battery to drop to the voltage.
