An implementation method is exemplarily provided below. The electronic device detection module 2 is electrically connected to the first conductive contact surface 11 of each power supply block 1 respectively. A current detecting unit for measuring a current signal between any two or more power supply blocks 1 is built in the electronic device detecting module 2, and a DC power supply is provided in the power supply device, and the DC power supply is respectively electrically connected to each power supply block 1 connection. When the electronic device is not placed on the power supply device, the current value measured by the current detecting unit in the electronic device detecting module 2 is 0 because the power supply blocks are disconnected.

Since the voltage value between the power supply terminals of the electronic device is positively correlated with the battery power of the battery in the electronic device, optionally, the electronic device detection module has a built-in voltage meter for measuring between any two or more power supply blocks. When an electronic device is accessed, the electronic device detecting module measures a voltage between the power supply blocks of the access electronic device, obtains a voltage value between the power supply blocks of the access electronic device, and obtains the voltage value and the standard value. The voltage value of the electronic device battery is compared with the voltage value correspondence table between the power supply terminals of the electronic device, thereby obtaining the battery power of the electronic device. In this case, the detection result includes at least the polarity of each power supply terminal of the accessed electronic device, the related information of the power supply block of the access electronic device, and the current battery power of the electronic device. On the basis of the foregoing technical solution, optionally, after obtaining the current battery power of the electronic device, the control module compares the battery power with a preset value, and further determines whether to control the opening and closing of the strobe switch in the power supply line to ensure Electronic equipment will not be damaged by overcharging. Exemplarily, assuming that the preset value is 100%, if the detected current battery power of the electronic device is 100%, the electronic device is considered to be full, and the control module controls the power supply block connected to the electronic device in the power supply line to be connected. The strobe switch is turned off, so that the external power supply stops supplying power to the electronic device, thereby achieving the purpose of protecting the electronic device.

The leakage relay is electrically connected to the power supply line in the power supply device to detect whether the power supply device is leaking. Further, the leakage protection unit further includes an alarm device electrically connected to the leakage relay for issuing an alarm signal to alert the user when a leakage phenomenon is detected in the power supply device. Alternatively, the leakage protection unit further includes a switch unit, one end of the switch is electrically connected to the leakage relay, and the other end is electrically connected to the power supply device, and is configured to control the power supply device to be turned off when detecting that there is a leakage phenomenon in the power supply device.
