Abstract: A power supply management method applied to a charging station system including a plurality of battery swapping cabinets and an AC discharging cabinet. Each battery swapping cabinet receives an AC mains, and includes a plurality of batteries. The method includes steps of: (a) determining that the AC mains fails to supply power normally so that the batteries cannot be powered by the AC mains and operated in a power-off idle mode, (b) selecting one of the batteries to discharge for providing the power required by the charging station system, (c) determining the selected battery is in a discharging and loaning mode to select one battery swapping cabinet to operate in a discharging mode, and (d) supplying power to the AC discharging cabinet by converting the power of the battery through the selected battery swapping cabinet.

Abstract: A battery swapping cabinet includes an AC-to-DC converter, a plurality of charging/discharging DC converters, a plurality of batteries, a first auxiliary DC converter, and a main board. The AC-to-DC converter converts an AC power supply into a DC bus voltage. The charging/discharging DC converters respectively receive the DC bus voltage and convert the DC bus voltage into a plurality of DC voltages. The plurality of batteries receives the plurality of DC voltages. The first auxiliary DC converter receives the DC bus voltage and converts the DC bus voltage into a first state voltage. The main board receives the first state voltage and a second state voltage. According to a state of the AC power supply, the main board provides the first state voltage or the second state voltage to the plurality of batteries to maintain the power required for the uninterrupted operation of the plurality of batteries.

Abstract: A method for identifying a signal transmission device includes: reading attribute information from a memory device by a first device of a signal processing system, wherein the attribute information records information regarding at least one attribute of the signal transmission device that is coupled between the first device and a second device of the signal processing system; determining the at least one attribute of the signal transmission device by the first device according to the attribute information; and setting a maximum value or a minimum value of a signal output by the first device or the second device according to the at least one attribute.
