Abstract: A smart pole power system including a distribution board, multiple alternating current (AC) power devices, a power splitter, and at least one wired network device is provided. The distribution board is coupled to an AC power source to provide multiple AC voltages. The AC power devices are coupled to the distribution board and receive the AC voltages. The AC power devices include a network switch. The network switch receives one of the AC voltages to provide at least one network power supply signal. The power splitter is coupled to the network switch. The power splitter receives one of the network power supply signals and separates a supply voltage signal from the received network power supply signal. The at least one wired network device includes a non-network power supply device. The non-network power supply device is powered by the supply voltage upon reception of the supply voltage.

Abstract: A charging and discharging circuit is provided, which includes a charging and discharging control circuit, a first connection port, a first switch circuit, a second switch circuit, a second connection port, a third switch circuit, a fourth switch circuit, and an identification logic circuit. The identification logic circuit determines a mode of the first connection port according to a first channel configuration signal of the first connection port, the charging and discharging control circuit switches the first switch circuit and the second switch circuit according to the mode of the first connection port, and the charging and discharging control circuit determines a mode of the second connection port according to a second channel configuration signal of the second connection port, so as to switch the third switch circuit and the fourth switch circuit.
