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 charger includes a first connection port, a second connection port, a DC-DC converter, a first microcontroller, and a second microcontroller. The DC-DC converter is configured to convert a first DC voltage into a second DC current/voltage according to a regulation signal, and output the second DC current/voltage through the second connection port. The second DC voltage is lower than the first DC voltage. The first microcontroller is configured to communicate with a DC charging station by handshake via the first connection port. When the handshake between the first microcontroller and the DC charging station succeeds, the first microcontroller generates a regulation indication according to a result of the handshake between the first microcontroller and a battery, the second microcontroller generates the regulation signal according to the regulation indication, and the first DC voltage is supplied by the DC charging station.

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.
