The first concrete example of the present invention will be described in more detail below.

FIG. 1 is a block diagram of a mobile phone according to the present invention.

The mobile phone 1 includes a control unit 3 for controlling the operation of the mobile phone 1, a memory 4 for storing necessary data, an AD converter 5 for converting an analog voltage into a digital value, and an RF signal. A wireless unit 6 that performs modulation and demodulation and an RF signal that is efficiently transmitted in the air,
An antenna 7 for receiving radio waves is provided.

Power is supplied from a battery pack (hereinafter referred to as a battery) 2 to each part of the above-mentioned portable telephone 1 of the present invention. The battery 2 is a rechargeable battery.

Now, in the standby reception state of the mobile phone 1, since the position has already been registered, there is almost no need to transmit data to the base station (not shown). Therefore, the processing in the control unit 3 is reduced, and further, it is not necessary to transmit the RF modulated wave from the wireless unit 6, so that the power supply to the transmission circuit such as the power amplifier in the wireless unit 6 can be turned off. It is possible.

On the other hand, in the call state, since the radio section 6 transmits the RF modulated wave, the current consumed in the radio section 6 is
Increased compared to standby reception. Furthermore, since the control unit 3 also performs a process of generating data for transmission to the wireless unit 6, current consumption increases as compared to the standby state.

Therefore, generally, in a mobile telephone, when comparing the current consumption in the standby reception state with the current consumption in the call state, the current consumption becomes larger in the call state.

FIG. 2 shows the discharge characteristics of the battery 2.

FIG. 2 (a) shows the discharge characteristic during continuous communication, and FIG. 2 (b) shows the discharge characteristic during continuous standby reception. The horizontal axis in the figure is the elapsed discharge time of the battery, and the vertical axis is the vertical axis. It represents the battery voltage.

The characteristic of FIG. 2A shows the discharge characteristic in a continuous communication state in which a constant transmission power (maximum power in this embodiment) is transmitted, and the battery voltage drops as time elapses. It shows the tendency to go.

That is, the battery voltage at a certain time t1 is V1, and then the voltage when the discharge is continued until the time t2 is V1.
Set to 2. Here, the voltage V2 is the minimum voltage at which the operation of the mobile phone 1 can be guaranteed.

The characteristic of FIG. 2 (b) shows the discharge characteristic in the continuous standby state and shows the tendency that the battery voltage drops with the passage of time, but it consumes less current than in the call state. Therefore, the slope of the discharge characteristic is gentle.

In this discharge characteristic curve, a certain time t
The battery voltage at a is V1, and then the voltage when discharging is continued until time tb is V2. Here, the voltage V2
Is the minimum voltage at which the operation of the mobile phone 1 can be guaranteed, as described above.

Then, the two discharge characteristics of FIGS. 2A and 2B are stored in the memory 4 in advance. At this time,
It suffices to store the discharge time during continuous communication and the discharge time during continuous standby reception, which correspond to the battery voltage (for example, every 0.05 V) at equal intervals.

Next, a method of detecting the remaining battery time when the voltage across the battery 2 is V1 will be described.

First, the voltage measuring means of the control unit 3 is AD
The output voltage V of the battery 2 is measured via the converter 5.
Then, the control unit 3 determines, from the data tables 41 and 42 stored in the memory 4, the discharge time t1 during the continuous call, which is the closest to the measured battery voltage V1, and the discharge time ta during the continuous standby reception, respectively. read out.

At the same time, the continuous call time t2 at the minimum voltage V2 that can guarantee the operation of the mobile phone 1 and the continuous waiting time tb are read.

Then, the control unit 3 calculates the remaining battery time during continuous communication and the remaining battery time during continuous standby reception as follows.

(Battery remaining time during continuous call) = t2-t1 (1) (Battery remaining time during continuous standby reception) = tb-ta (2) Next, battery voltage = 3.71V, operation Guaranteed voltage V2 = 3.
Taking the case of 2V as an example, the first table of FIG. 3 and the second table of FIG.
This will be specifically described with reference to the table.

FIG. 3 (a) shows the discharge characteristic during continuous communication, and FIG. 3 (b) shows the table value (battery voltage-discharge time) in which this discharge characteristic data is stored in the memory 4. .

In this example, it is assumed that the measured output voltage value of the battery 2 is 3.71 [V].

The control unit 3 reads the table 41 of the memory 4 and searches the data in the table 41 for the battery voltage closest to the measured voltage value to obtain V1 = 3.7V.
From this data, the discharge time t1 = 53.45 minutes during continuous communication at V1 = 3.7V is obtained.

On the other hand, FIG. 4A shows the discharge characteristics during standby, and FIG. 4B shows a table value (battery voltage-discharge time) in which this discharge characteristic data is stored in the memory 4. There is.

In this example, the output voltage value of the battery 2 is 3.
Since it is 71 [V], the control unit 3 searches the data in the table 42 for the battery voltage closest to the measured voltage, and obtains V1 = 3.7V. From this data, V1 =
Continuous standby discharge time t1 = 26 at 3.7V
Get 7.25 minutes.

Since the operation guarantee voltage V2 = 3.2V,
Based on the tables of FIGS. 3 and 4, the control unit 3 sets t2 =
This gives 110.23 minutes and tb = 551.15 hours.

The control unit 3 performs the calculations of (1) and (2) described above, and obtains the remaining battery time during continuous communication and during continuous standby.

(Battery remaining time during continuous communication) = t2-t1
= 110.23-53.45 = 56.78 minutes (= 56 minutes 47 seconds) (remaining battery time during continuous standby reception) = tb-ta = 5
51.15-267.25 = 283.9 hours (= 283
Then, by displaying the remaining battery time obtained as described above, the user can grasp the accurate remaining battery time according to the application. (Second Specific Example) FIG. 6 is a block diagram showing a configuration of a telephone set according to a second specific example of the present invention, and FIG. 7 is a diagram showing discharge characteristics of a battery during continuous call according to the second specific example. FIG. 8 is a diagram showing the discharge characteristics of the battery during continuous standby in the second specific example, and FIG.
6 is a flow chart for explaining the operation of the second specific example.

In the second specific example, in addition to the configuration of the first specific example, a temperature sensor 8 is further provided, and the current temperature information is always reported to the control unit 3. Furthermore, the discharge characteristics during continuous communication and the discharge characteristics during continuous standby are each composed of a plurality of discharge characteristic data so as to correspond to a predetermined temperature.

FIG. 7 (a) shows discharge characteristics at each temperature during continuous communication, and FIG. 7 (b) shows table values (battery voltage-discharge time) corresponding to each temperature.

Further, FIG. 8A shows the discharge characteristics at each temperature during continuous standby, and FIG. 8B shows the table value (battery voltage-discharge time) corresponding to each temperature. .

Generally, at low temperature, the discharge time tends to be shorter than at room temperature. In the second specific example, in addition to room temperature (+ 20 ° C.), low temperature (+ 5 ° C.) and high temperature (+ 35 ° C.).
The discharge characteristics at each temperature (° C) are shown.

When detecting the remaining battery time, the control unit 3 retrieves the closest temperature from each table based on the output voltage of the battery 2 measured by the AD converter 5 and the temperature information detected by the temperature sensor 8. , The battery remaining time at the current time at the current temperature is obtained by searching for the closest battery voltage.

Next, ambient temperature = + 7 ° C., battery voltage = 3.
A specific description will be given by taking as an example the case where the voltage is 71V and the operation guarantee voltage V2 = 3.2V.

First, the temperature sensor 8 first detects the ambient temperature = + 7 ° C., and then the output voltage value of the battery 2 is measured to obtain the voltage value 3.71 [V]. Control unit 3
Receives the report of ambient temperature = + 7 ° C., and searches the temperature table closest to the measured temperature from the first and temperature tables 41A and 42A stored in advance in the memory 4. Then, in the case of this example, a table value (battery voltage-discharge time) at a low temperature (+ 5 ° C.) is selected and used.

Next, the control unit 3 searches the low temperature (+ 5 ° C.) table 41A for the battery voltage closest to the measured voltage value 3.71 [V], and obtains V1 = 3.7V. As a result,
At the low temperature (+ 5 ° C.), V1 = 3.7V, the current continuous discharge time t1 = 43.45 minutes is obtained.

On the other hand, the control unit 3 controls the low temperature (+5) in which the table value of the discharge characteristics during continuous standby in FIG. 8 is stored.
From the table 42A of (° C), the measured voltage value is 3.71 [V]
To find the battery voltage closest to and obtain V1 = 3.7V,
At the low temperature (+ 5 ° C.), V1 = 3.7V, the current continuous discharge time t2 = 217.25 minutes is obtained.

Since the operation guarantee voltage V2 = 3.2V,
From the low temperature (+ 5 ° C.) tables of FIGS. 7 and 8, the control unit 3 determines that t2 = 100.23 minutes and tb = 501.1.
Get 5 minutes.

The control unit 3 calculates the above-mentioned (1) and (2) and obtains the remaining battery time for each of the continuous call and the continuous standby.

(Battery remaining time during continuous communication) = t2-t1
= 100.23-43.45 = 56.78 minutes (= 56 minutes 47 seconds) (remaining battery time during continuous standby reception) = tb-ta = 5
01.15-217.25 = 283.9 hours (= 283
Time 54 minutes) With the above configuration, it is possible to report a more accurate current remaining discharge time to the user with respect to the discharge time that changes depending on the temperature conditions.

In the above example, the voltage value is set at equal intervals to create the discharge characteristic table, but the discharge characteristic table is created by setting the discharge time at equal intervals (for example, every 5 minutes). It may be configured as follows.

Further, by using a table in which the voltage value is made fine in the vicinity of the minimum operating voltage V2, it is possible to more accurately detect the time immediately before the power supply is cut off.

As described above, in the second embodiment of the present invention, the battery 2 which is the power source of the portable telephone, the voltage measuring means 5 for measuring the output voltage value of the battery 2, and the temperature of the battery are measured. The temperature measuring means 8 and the discharge characteristic of the battery, which is the relationship between the elapsed time in the case of continuous communication and the output voltage value of the battery corresponding to this elapsed time, are recorded for each predetermined temperature.

The second table 42A, the memory 4 storing the first table 41A and the second table 42A, and the voltage measuring means 5 measure the output voltage value of the battery and the temperature measuring means 8 With the battery The temperature is measured, and the output voltage value that is the closest to the measured temperature value and that is the closest to the measured voltage value is selected from the first table 41A, and the discharge time at the current time point corresponding to the selected voltage value is selected.
