Description

A device for improving the efficiency and extending the life of the camcorder battery {APPARATUS FOR ENHANCING EFFICIENCY AND PROLONGING LIFE-CYCLE OF CAMCORDER BATTERY}

The present invention relates to a camcorder (CAMCORDER: CAMera reCORDER), and more particularly to a device for improving the efficiency and life of the camcorder battery.

In a portable electronic product using a battery (eg, a camcorder, etc.), when the battery is discharged and falls down to a voltage level at which normal operation is impossible, abnormal operation may occur in the electronic product. Therefore, the battery voltage should not fall to the voltage level which cannot operate normally. For example, a video camcorder (camera recorder) is a portable photographing apparatus that can record and record various scenes desired by a user while freely moving in a portable state. Portable electronics such as camcorders, etc., have a larger portion of batteries than household electronics. Therefore, care should be taken not to drop the battery voltage to a voltage level at which the battery cannot operate normally.

In the camcorder, the main body microcomputer sets the battery down mode during battery operation, and stops the operation of the camcorder set when the battery voltage reaches, for example, about 5.5V. At this time, the camcorder user must recharge the camcorder battery to operate the set normally. However, when the camcorder battery is discharged to 5V and then recharged to fully charge, it is fully charged, but as the battery is frequently recharged at 5.5V, a memory effect occurs in the battery, thereby decreasing the battery efficiency. As a result, the camcorder battery becomes shorter in life and shorter in life.

To improve this, you need to use a charger with a refresh function, which has the disadvantage of longer charging time (more than 8 hours).

Accordingly, an object of the present invention is to provide an apparatus for improving the battery efficiency and extending the life of a camcorder battery.

In accordance with the above object, the present invention, the battery is sufficiently discharged to always 100% full charge when charging to extend the efficiency and life time of the battery.

More specifically, the present invention provides a device for improving the efficiency and extending the life of a camcorder battery, when a battery voltage of a predetermined camcorder operation threshold level is detected, the battery down mode is set and the camcorder set operation is stopped and battery power discharge is controlled. A battery power discharging control unit and a battery power discharging circuit unit for discharging the power of the camcorder battery to the highest power level among the power levels at which the memory effect generated in the camcorder battery can be minimized based on the battery power discharging control. do.

In addition, the present invention provides a device for improving the efficiency and life of the camcorder battery, the battery power discharge control unit for setting the battery down mode, stop the camcorder set operation and control the battery power discharge based on the discharge control of the user, And a battery power discharge circuit unit for discharging the power of the camcorder battery to the highest power level among power levels at which the memory effect generated in the camcorder battery can be minimized based on the battery power discharge control.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are denoted by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a device configuration diagram for improving the battery efficiency and sleep of a camcorder according to an embodiment of the present invention, wherein a battery voltage of a preset camcorder operating threshold level is detected or set to a battery down mode based on a discharge control of a user. The microcomputer 10 which stops the camcorder set operation and controls the battery power discharge, and the power level of the power supply of which the memory effect generated in the camcorder battery can be minimized according to the battery power discharge control of the microcomputer 10. It consists of a battery power discharge circuit part 20 which discharges to a high power level.

The battery power discharge circuit 20 may include a first transistor Q1 that is turned on under the battery power discharge control of the microcomputer 10 and passes the power of the battery, and a power source through which the memory effect is minimized. The power level checking unit 16 which checks whether or not the highest power level is among the levels and outputs a check result, and until the battery reaches the highest power level among the power levels based on the check result of the power level checking unit 16; And second and WP3 transistors Q2 and Q3 that are switched and controlled to discharge power.

2 is a flowchart illustrating an operation performed by the microcomputer 10 of FIG. 1 according to an embodiment of the present invention.

Hereinafter, an operation according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

When the battery 12 used in the camcorder consumes power as the camcorder operates, and the power is discharged to 5.5V, the battery voltage sensing circuit 14 senses the voltage level of the battery 12 and checks it and provides it to the microcomputer 10. The voltage of about 5.5V in the camcorder is an example of a predetermined operation threshold level in the camcorder. The microcomputer 10 checks the battery voltage in step 100 of FIG. 2, and determines whether the battery voltage detected from the battery voltage sensing circuit 14 is 5.5V in step 101. If the voltage is 5.5V or higher, proceed to step 102 to determine whether the discharge control is performed by the user. If neither the discharge control is performed by the user or not, proceed to step 103 to maintain the binary logic "L" state continuously applied to the discharge control port P. . In the binary logic "L" state, the battery power discharge circuit unit 20 does not operate.

On the other hand, if the battery voltage reaches 5.5V in step 101 or discharge control by the user in step 102, the microcomputer 10 proceeds to step 104 to set the battery down mode, and in step 105 to the discharge control port P. Output the binary logic " L " state and enter the sleep mode in step 106. The camcorder will not operate when it is in sleep mode.

When the microcomputer 10 outputs the binary logic “L” state to the discharge control port P in step 105, the first transistor Q1 of the battery power discharge circuit unit 20 is turned on. Accordingly, the battery 12 is powered down by the first transistor Q1, the resistor R1, and the resistor R2 and applied to the input terminal Vin of the power level checking unit 16. The resistors R1 and R2 are set to have a resistance value of 4.5V at the input terminal Vin of the power supply level check unit 16 when the power supply of the battery 12 becomes 5V. The power supply level checking unit 16 outputs an "H" state to the output stage CS when a voltage greater than 4.5V (5V in the battery 12) is applied to the input terminal Vin, and outputs an "L" state to the output stage CS when less than 4.5V. The power level checking unit 16 is a regulator IC, and the S8420AF chip is used as an example in the present invention.

When the output terminal CS of the power level check unit 16 outputs the "H" state, the second transistor Q2 and the third transistor Q3 are turned on. Accordingly, the power supply of the battery 12 having the 5.5V voltage level is connected to the third transistor Q3. Discharge to ground through resistor R3. When the voltage of the battery 12 reaches 5V after being discharged as described above, the output terminal CS of the power level checking unit 16 outputs the "L" state. Accordingly, the second transistor Q2 and the third transistor Q3 are turned off. As a result, the battery 12 is powered down by 5V. 5V is the highest level value of the power supply level at which the memory effect according to the embodiment of the present invention can be minimized.

After this operation, if the user charges the battery using the charger, the battery can be fully charged.

On the other hand, in the present invention, the user can immediately control the discharge. The user may view through a display unit displaying a battery power state, for example, an eye view finder (EVF). Even when the current battery power is in a battery down mode, the user may perform discharge control to fully charge the battery again. According to the present invention for the discharge control may be provided with a separate discharge control button, may be used in combination with the existing keys. Discharge control buttons can also be implemented on the EVF screen. When the discharge control is made by the user, the microcomputer 10 performs steps 104, 105, and 106 of FIG.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of utility model registration claims and utility model registration claims.

As described above, the present invention fully discharges the battery so that it is fully charged at all times during charging, thereby extending the efficiency and life time of the battery.
