Charging devices and related management systems and methods for charging fee management

1. A charging fee management method for electric vehicles for use in a charging device, wherein the charging device can be operated in a plurality of operation modes, comprising:

receiving a charging request for charging an electric vehicle;

instructing the charging device to perform a charging process for the electric vehicle in response to the charging request; and

calculating a charging fee for the charging process, wherein the charging fee is calculated based on charging data generated during the respective operation mode of the charging device and a respective charging method for each operation mode,

wherein the operation modes comprise a first operation mode having a first charging method and a second operation mode having a second charging method, and the method further comprises the steps of:

calculating the charging fee based on the first charging method when the charging device is operated in the first operation mode;

determining whether the charging device is operated in the second operation mode;

calculating the charging fee based on the second charging method when the charging device is operated in the second operation mode; and

calculating the charging fee based on the first charging method when the charging device leaves the second operation mode.

2. The method of claim 1 , wherein the operation modes comprise a first operation mode having a first charging method and a second operation mode having a second charging method, and the charging fee is a sum of a first charging fee and a second charging fee, wherein the first charging fee is calculated according to the charging data during the first operation mode and the first charging method, and the second charging fee is calculated according to the charging data during the second operation mode and the second charging method.

3. The method of claim 2 , wherein the charging data comprises a charging period and a power use of the charging process, and the first charging method is calculated based on the charging period during the first operation mode, and the second charging method is calculated based on the power use during the second operation mode.

4. The method of claim 1 , further comprising:

recording a plurality of charging requests for the charging device, and the corresponding records of charging fee and power use for each charging request in a predefined time interval, wherein each charging request has a user identification data; and

retrieving the records of charging fee and power use for a specific user identification data, and generating a charging fee report for the specific user identification data.

5. The method of claim 1 , further comprising:

recording a plurality of charging requests for the charging device, and the corresponding records of charging fee and power use for each charging request in a predefined time interval, wherein each charging request has an electric vehicle identification data; and

retrieving the records of charging fee and power use for a specific electric vehicle identification data, and generating a charging fee report for the specific electric vehicle identification data.

6. The method of claim 1 , wherein the charging device outputs power based on an upper limit of the charging device during the first operation mode, and the power output by the charging device during the second operation mode is dynamically adjusted based on a load balance profile executed by the charging device.

7. The method of claim 1 , wherein the charging device electrically couples to a power supply utility with a TOU (Time Of Use) rate, and the charging fee is calculated based on the TOU rate, the charging data generated during the respective operation mode of the charging device and the respective charging method for each operation mode.

8. A charging device for output power to an electric vehicle for a charging process, wherein the charging device can be operated in a plurality of operation modes, comprising:

a communication circuit receiving a charging request corresponding to an electric vehicle via a network; and

a processing circuit coupled to the communication circuit, performing a charging process for the electric vehicle in response to the charging request when the communication circuit received the charging request, and calculating a charging fee for the charging process, wherein the charging fee is calculated based on charging data generated during the respective operation mode of the charging device and a respective charging method for each operation mode, wherein the operation modes comprise a first operation mode having a first charging method and a second operation mode having a second charging method, and the processing circuit further calculates the charging fee based on the first charging method when the charging device is operated in the first operation mode, determines whether the charging device is operated in the second operation mode, calculates the charging fee based on the second charging method when the charging device is operated in the second operation mode, and calculates the charging fee based on the first charging method when the charging device leaves the second operation mode.

9. A management system, comprising:

a computer device; and

a charging device for output power to an electric vehicle for a charging process, wherein the charging device can be operated in a plurality of operation modes, and the charging device connects to the computer device via a network, comprising:

a communication circuit receiving a charging request corresponding to an electric vehicle via the network; and

a processing circuit coupled to the communication circuit, transmitting the charging request to the computer device when the communication circuit received the charging request, such that the computer device, in response to the charging request, instructs the processing circuit to perform a charging process for the electric vehicle, and calculates a charging fee for the charging process, wherein the charging fee is calculated based on charging data generated during the respective operation mode of the charging device and a respective charging method for each operation mode, wherein the operation modes comprise a first operation mode having a first charging method and a second operation mode having a second charging method, and the processing circuit further calculates the charging fee based on the first charging method when the charging device is operated in the first operation mode, determines whether the charging device is operated in the second operation mode, calculates the charging fee based on the second charging method when the charging device is operated in the second operation mode, and calculates the charging fee based on the first charging method when the charging device leaves the second operation mode.
