Abstract

The charging device contains a connection unit, a measurement unit, an identification unit, a processing unit, a display unit, a current distribution unit, etc. The connection unit has at last a device connection element for connecting an electronic device. The charging device automatically distributes charging current based on preset parameters and multiple charging devices could be cascaded. As such, all connected electronic devices could be fully charged at high speed under full specification sequentially, and the maximum charging current provided and the number of connected electronic devices is expanded.

Claims

1. A charging device, comprising:

a connection unit having at least a device connection element for connecting at least an electronic device;

a measurement unit connected to said connection unit measuring a real-time current amount supplied by said connection unit to each of said electronic devices;

an identification unit connected to said connection unit identifying an identification data of electrical characteristics for each of said electronic devices;

a processing unit connected to said connection unit, identification unit, and measurement unit, said processing unit registering said identification data, built-in charging mode data, and said real-time current amount for each of said electronic devices as a registration information and issuing a current distribution command involving built-in charging policy data; and

a current distribution unit connected to said processing unit, said connection unit, and a power unit capable of supplying a maximum current amount, said current distribution unit, based on said current distribution command, conducting charging to said electronic devices so that total charging current does not exceed said maximum current amount.

2. The charging device according to claim 1, wherein said processing unit further comprises:

a first data element storing charging mode data for said electronic devices;

a second data element storing data for a plurality of charging policies, each involving parameters for charging modes, weighting factors or priorities, and cascading time sequence;

a third data element transforming measurement result from said measurement unit into corresponding registration information for said electronic devices'"'"' charging modes; and

a control element receiving identification data, locating corresponding charging mode data by registration information, and issuing a current distribution command in accordance with corresponding charging policy.

3. The charging device according to claim 1, wherein said charging mode data contains the amount of charging current and related control method under fast charging mode, slow charging mode, and wait-for-charging mode for each of said electronic devices.

4. The charging device according to claim 1, wherein said power unit further comprises:

a power connection element electrically connected to a power source; and

a power conversion element connected between said power connection element and said current distribution unit, said power conversion element transforming the electricity received by said power connection element from said power source into appropriate forms for said device connection elements.

5. The charging device according to claim 1, further comprising a display unit connected to said processing unit, said display unit comprising a plurality of display element.

6. The charging device according to claim 5, wherein each of said display elements shows a current charging mode of a corresponding device connection element.

7. The charging device according to claim 1, further comprising:

a communication interface unit configured with a communication protocol and connected to said processing unit and said current distribution unit;

at least an external connection element connected to said communication interface unit; and

a cascading element connected to said communication interface unit for connecting an external connection element of another identically-structured charging device;

wherein said cascaded charging devices jointly determine a master-slave hierarchy following said communication protocol and distribute the charging currents of said charging devices to said device connection elements.

8. The charging device according to claim 7, wherein said external connection elements from cascaded charging devices provide information about charging mode data and communication protocol to each other;
