[0077] As an example, the first signal detection module 117 includes a first switch identification circuit, a first temperature acquisition circuit, and a charge / discharge switch detection circuit connected to the first power supply circuit 114. The first switch identification circuit identifies the closed state of the first magnetic switch and detects whether the portable charging pile is plugged into the wall mount 1. The first temperature acquisition circuit may include a first single-bus control temperature sensor disposed on the fixed female mount 115 to detect the temperature of the fixed female mount 115 and acquire it as a first temperature signal; the charge / discharge switch detection circuit acquires the charge / discharge switch signal and detects whether the charge / discharge switch (e.g., a first relay) is engaged.

[0078] The first controller 111 controls the operation of the first power supply circuit 114 based on the closed state of the first magnetic switch, the first temperature signal, and the charge / discharge switch signal. For example, when the first controller 111 detects that the first magnetic switch is closed and the first temperature signal is not greater than a preset temperature signal, it controls the first relay to be engaged. Engaging the first relay after detecting the first magnetic switch is closed prevents the fixed socket 115 from becoming energized and prevents electric shock. When the first controller 111 detects that the first temperature signal is greater than the preset temperature signal, it controls the charge / discharge switch to be disconnected to stop charging and discharging. And / or, the second controller 211 can also control the operation of the second power supply circuit 215 based on the closed state of the first magnetic switch, the first temperature signal, and the charge / discharge switch signal. For example, when the first temperature signal is detected to be greater than the preset temperature signal, it controls the second power supply circuit 215 to be disconnected to prevent overheating. The second controller 211 controls the second power supply circuit 215 to operate based on the closed state of the second magnetic switch and the second temperature signal. For example, when the second controller 211 detects that the second magnetic switch is closed and the second temperature signal is not greater than a preset temperature signal, it controls the energy storage module 22 to charge the charging and discharging device 4; when it detects that the second temperature signal is greater than the preset temperature signal, it controls the second power supply circuit 215 to be disconnected, stopping the charging and discharging. And / or, the first controller 111 can also control the first power supply circuit 114 to operate based on the closed state of the second magnetic switch and the second temperature signal. For example, when it detects that the second temperature signal is greater than the preset temperature signal, it controls the first power supply circuit 114 to be disconnected to prevent overheating.

The first controller 111 can control the first power supply circuit 114 to operate based on the first address identification information. The second temperature acquisition circuit is also used to acquire second address identification information; specifically, when the fixed female connector 115 and the fixed male connector 216 are plugged in, the second temperature acquisition circuit can control the temperature sensor to change address 02 via the second single bus to obtain the second address identification information, which is used as the identity information verification of the portable power supply plug; and control the temperature sensor to change address 03 via the second single bus to obtain the third address identification information, which is used as the identity information verification of the portable power strip.

[0082] As an example, the first control board 11 also includes an emergency stop detection circuit 118 connected to the first power supply circuit 114.
