Generates a mobile phone charging voltage of V. In Fig. 11, since the first to fifth mobile phone charging circuit sections 321, 322, 323, 324, and 325 have the same configuration, the first mobile phone charging circuit section 321 is representatively shown for simplicity of explanation. Explain.

According to the electrical appliance safety standard mobile phone battery charger (K10001), in the normal charging mode (Normal Charging Mode), the output voltage of the charging voltage generating circuit unit 350 is defined as a DC voltage of 4.15 ~ 4. 23V. . On the other hand, the charging voltage generation circuit unit 350 generates a DC voltage of 4.25 ~ 4.5V in the fast charging mode. The charging voltage generating circuit unit 350 is connected to the mobile phone through the charging connection terminal 283 to charge the battery. For example, the charging voltage generating circuit unit 350 is connected between the charging voltage generating circuit unit 350 and the charging connection terminal 283. When charging, the charging display unit 331 is displayed in red and displayed in green when fully charged.

The first mobile phone charging circuit unit 321 includes a charging voltage generation circuit 350, a comparison circuit 360, an overcharge preventing circuit 370, and the like. The comparison circuit 360 compares the output of the charging voltage generator circuit 350 with the state of charge of the battery, and when the state of charge of the battery reaches point A in the graph shown in FIG. Is gradually charged, and when fully charged, the charging voltage generating circuit 350 is turned off. When the overcharge occurs due to a misrecognition of the charge amount of the mobile phone battery, that is, the remaining charge amount, etc. may occur. This overcharge is designed to prevent overcharge by the overcharge prevention circuit 370.

Here, the first cellular phone charging circuit unit 321 and the second cellular phone charging circuit unit 322 are programmed to control voltage, current, and temperature by the first microprocessor 341. The first to third microprocessors 341, 342 and 343 are each designed to control two cell phone charging circuits. Therefore, the composite charging device 200 according to the embodiment of the present invention can easily expand 2 to 20 charging connection terminals.

Meanwhile, the complex charging device 200 of the portable device according to the embodiment of the present invention may be changed to the normal charging mode or the quick charging mode, respectively, according to the design of the microprocessor. In addition, even in one composite charging device 200, the normal charging mode and the quick charging mode may be simultaneously implemented.

For example, as shown in FIG. 11, all of the first to third microprocessors 341, 342, and 343 may be programmed in the normal charging mode or the quick charging mode. In addition, the first and second microprocessors 341 and 342 are programmed in the normal charging mode, and the third microprocessor 343 is programmed in the fast charging mode, thereby providing a plurality of normal charging modes and one quick charging mode. It can be implemented in large multiple chargers. On the other hand, the first and third microprocessors 341 and 343 are programmed in the normal charging mode, and the second microprocessor 343 is programmed in the fast charging mode, thereby providing a plurality of normal charging modes and a plurality of quick charging modes. Can be implemented in a single multiple charger.

The composite charging device 200 of a portable device according to an embodiment of the present invention may charge five mobile phones at the same time by way of example, and also, by using one or more USB terminals, one or more mobile devices (PDA, MP3). , iPOD, digital camera, camcorder, etc.) is designed to charge at the same time, but is not limited thereto.

12 shows an actual circuit portion 290 implemented in accordance with an embodiment of the present invention. 12 illustrates only the SMPS constant voltage generator 310, the first and second charging circuits 321 and 322, and the first microprocessor 341 for the sake of simplicity. 3, the third to fifth charging circuit units 323, 324, and 325, and the second and third microprocessors 342 and 342 may be identical to the illustrated circuit.

FIG. 13 is a graph conceptually illustrating a charging method of a battery of a portable device in a normal charging mode and a rapid charging mode.

In FIG. 13, the charging mode of the cellular phone may include a normal charging mode and a quick charging mode. Normal charging mode is a charger for home use. Charge the applied voltage of about 4.1 ~ 4.25 V to point A which is charged up to 70 ~ 80% of the battery's charge, considering the battery's charge (Q1 + Q3). , Slowly charging while reducing the voltage until fully charged. Therefore, in the normal charging mode, the charging time is relatively long because the charging is performed stably without adversely affecting the battery.

On the other hand, in the case of the fast charging mode providing a charging service in a convenience store, etc., by applying a charge voltage of 4.25 ~ 4.5 V higher than the applied voltage of the normal charging mode, the charging time can be shortened. However, in the fast charging mode, the charge amount of the battery (Q1 + Q2) should be calculated relatively accurately, and the overcharge protection circuit should be designed more accurately. In the quick charge mode implemented in the present invention, it is preferable to turn off the applied voltage when the applied voltage of 4.25 to 4.5 V reaches point B after a predetermined time T1 has elapsed. Because, in order to prevent the blasting of the battery due to overcharging, by setting about 90% of the normal charge of the battery to the full charge, it is possible to fundamentally prevent overcharging. If necessary, the battery can be charged until it is fully charged while gradually decreasing the voltage in the normal charging mode, but it is not effective considering the time.
