First Claim
Patent Images
1. A power supply system with a power storage device, comprising:
- an AC-to-DC power supply receiving an alternating current of external input, transforming the alternating current into a first direct current, and indicating the existence of the alternating current by using a tag;
a power storage device coupled with the AC-to-DC power supply, and including a battery charger and a rechargeable battery, wherein the battery charger receives the first direct current and generates a charging direct current to electrify the rechargeable battery, the rechargeable battery outputs a second direct current;
a DC-to-DC converter coupled with the AC-to-DC power supply and the rechargeable battery which selects the first direct current or the second direct current as an input power source, and generates at least one working power source according to the input power source; and
a power management device coupled to the DC-to-DC converter to receive the at least one working power source and output at least one output direct current, connected to the AC-to-DC power supply, the battery charger, the rechargeable battery, and the DC-to-DC converter by a bus, wherein the power management device detects and controls the AC-to-DC power supply, the battery charger, the rechargeable battery, and the DC-to-DC converter by the bus;
wherein the power management device accesses the tag via the bus and transmits a control signal to the DC-to-DC converter to drive the DC-to-DC converter to select the first direct current as the input power source when the tag indicates existence of the alternating current.
