As a result, the battery pack 221 may have a significantly reduced effect due to overcharging, overheating, explosion, and fire compared to the conventional terminal battery.

The stabilization circuit 222 may receive the charging power charged in the battery pack 221 and provide power to the terminal 10 using the provided charging power. The stabilization circuit 222 may control the supply and interruption of the power, or adjust the magnitude or intensity of the power (for example, voltage or current) supplied when the power is supplied.

The power control circuit 223 may control a power supply operation of the stabilization circuit 222. The power control circuit 223 may control the stabilization circuit 222 to supply or cut power, and may adjust the power supplied through the stabilization circuit.

For example, if the power control circuit 223 detects an abnormal operation of the terminal 10, the power control circuit 223 may control the stabilization circuit to cut off power to the terminal 10. To this end, the power supply control circuit 212 may be provided with a circuit that detects an abnormal operation of the terminal 10 or may be controlled by the test device 20 that detects an abnormal operation of the terminal 10. .

In addition, when performing the app test for the plurality of terminals, the power control circuit 223 may adjust the power provided to each of the plurality of terminals according to the manufacturer or model name.

On the other hand, the power control circuit 223 may measure the amount of power supplied to the terminal 10. Here, the amount of power may be an average of the power supplied for a predetermined time.

According to an embodiment, the power control circuit 223 may adjust the remaining charge of the battery pack 221 based on the measured power amount. For example, the power control circuit 223 increases the remaining charge of the battery pack 221 when the measured power amount is more than a predetermined reference value, that is, connects an external power source to the battery pack 221 to charge the battery pack 221. You can. In addition, when the measured power amount is less than a predetermined reference value, the power control circuit 223 may reduce the remaining charge of the battery pack 221, that is, cut off the external power supplied to the battery pack 221. As a result, it is possible to reduce the effects of overcharging of the battery pack 221 during a long app test period, thereby providing a stable power supply for app testing.

According to an embodiment, the power control circuit 223 may control the remaining amount of charge of the battery pack 221 to maintain a predetermined reference value, for example, 50% or more (100% if fully buffered). At this time, the power control circuit 223 controls to charge the battery pack 221 by connecting an external power source to the battery pack 221 when the remaining charge of the battery pack 221 is 30%. When the remaining charge is 70%, the external power supplied to the battery pack 221 may be cut off.

According to an embodiment, the power control circuit 223 may adjust the remaining charge of the battery pack 221 based on the number of terminals under app testing. For example, when the number of terminals performing the app test is adjusted to maintain the charge remaining of the battery pack 221 more than 70%, and when the number of terminals performing the app test 7 of the battery pack 221 The remaining charge can also be controlled to maintain 50% or more. As such, the power control circuit 223 may be configured to increase the remaining charge of the battery pack 221 as the number of terminals performing the app test increases to secure the reserve power of the battery pack 221.

According to an embodiment, the power control circuit 223 may check the state of the battery pack 221 and cut off the external power supplied to the battery pack 221 when overheating of the battery pack 221 is detected. The power control circuit 223 transmits an alarm signal for notifying the interruption of the app test to the test device 40 when the external power is cut off or the app test is not possible because the battery level of the battery pack 221 is less than a predetermined reference value. Can be. In addition, the power control circuit 223 monitors the power supply or the battery pack 221 supplied to the terminal, and if the power supply is suddenly changed (for example, an error occurs, power supply failure, test stop request, etc.), the current app The test device 20 may request a state storage signal for requesting storage of the current state of the terminal 10 under test.

The power module 121 having the structure proposed in FIGS. 3 and 4 may perform an app test without using a terminal battery. On the other hand, in the case of directly using the external power source as shown in Figure 3, when the power outage, etc. is forced to stop the app test operation. Since the app test operation is performed by operating the terminal 10 for a long time, external power may not be maintained continuously due to factors such as power failure.

However, if the power module 121 additionally includes the battery pack 221 as shown in Figure 4, even if a situation in which the external power is cut off, since the power supply to the terminal for testing the app can stop the app test operation It can be done without.
