Abstract

An electrical energy transferring device coupled to an electrical energy receiving device is provided. The electrical energy transferring device includes an electrical source measuring unit and a power indicating unit. The electrical source measuring unit detects a power consumption and/or a charging status of the electrical energy receiving device. The power indicating unit is coupled to the electrical source measuring unit for showing the power consumption and/or the charging status of the electrical energy receiving device by a color signal and/or an audio signal.

Claims

1. An electrical energy transferring device coupled to an electrical energy receiving device, comprising:

at least one socket;

an electrical source measuring unit for detecting power consumption of the electrical energy receiving device; and

a power consumption indicating unit coupled to the electrical source measuring unit for showing the power consumption of the electrical energy receiving device by a color signal,

the power consumption indicating unit surrounding the at least one socket,

wherein the power consumption indicating unit includes a plurality of single-color display elements for showing the power consumption of the electrical energy receiving device by respective single-color display regions,

each of the single-color display regions has a display buffer hysteresis region, and

when the display buffer hysteresis region is reached, the single-color display region is switched.

2. The electrical energy transferring device according to claim 1, further comprising:

an upper power limit selection unit for setting an upper power limit of the electrical energy transferring device; and

/or

a protection unit for breaking off a power input path of the electrical energy transferring device if the electrical energy transferring device detects that the power consumption of the electrical energy receiving device is over a threshold.

3. The electrical energy transferring device according to claim 1, wherein the electrical energy transferring device comprises a power extension cord, or a charger or a transmission line.

4. The electrical energy transferring device according to claim 3, wherein, the electrical energy transferring device comprises a plurality of sockets, the power consumption indicating unit indicates the sum of power consumptions of all the sockets.

5. The electrical energy transferring device according to claim 3, wherein, the electrical energy transferring device comprises a plurality of sockets, and the power consumption indicating unit indicates the power consumption of the respective socket.

6. The electrical energy transferring device according to claim 1, wherein the electrical source measuring unit comprises:

a sensing unit for sensing a current or a voltage or a temperature or a leakage current;

a conversion unit coupled to the sensing unit for converting the current and/or the voltage and/or temperature and/or the leakage current; and

a signal processing unit coupled to the conversion unit for deciding the power consumption of the electrical energy receiving device, and/or whether the temperature is too high, and/or whether the leakage current exists according to an output from the conversion unit.

7. The electrical energy transferring device according to claim 1, wherein the electrical source measuring unit comprises:

a sensing unit for sensing a current or a voltage or a temperature or a leakage current;

a conversion unit coupled to the sensing unit for converting the current and/or the voltage and/or temperature and/or the leakage current;
