MOBILE POWER SUPPLY DEVICE AND POWER SUPPLY SYSTEM THEREOF
First Claim
1. A mobile power supply device, used for receiving an alternating current power from a power supply end, and charging a load device, the mobile power supply device comprising:
- a rectifier circuit, used for receiving the alternating current power to convert to a direct current power;
a battery set, comprising a plurality of battery units which are series connected to each other;
a charging control unit, electrically connected to the rectifier circuit and the battery set for receiving the direct current power to charging the battery set;
an output control unit, electrically connected to the battery set for adjusting and controlling the battery set to output a current and a voltage of the direct current power to the load device via a direct-current output port; and
a direct-current input port, electrically connected to the charging control unit and the battery set for inputting the direct current power to the battery set, wherein the direct-current input port comprises a determining pin, the charging control unit determines whether the charging control unit is connected to another mobile power supply device via the determining pin, to further control the battery set to receive the direct current power from another mobile power supply device.

Abstract
A mobile power supply device and a power supply system thereof are disclosed. The mobile power supply device is used for charging a load device. A rectifier circuit of the mobile power supply device is used for receiving an alternating current power to convert to a direct current power. A battery set includes a plurality of battery units series connected to each other. A charging control unit is used for receiving the direct current power to charge the battery set. An output control unit is used for controlling the battery set to output the direct current power to the load device via a direct-current output port. A direct-current input port is used for inputting the direct current power to the battery set, wherein the direct-current input port includes a determining pin for determining whether the charging control unit connects to another mobile power supply device.
