Abstract

A wireless battery management system manages at least one battery unit, and the system includes at least one battery tester and a wireless terminal apparatus. The at least one battery tester is electrically connected to the at least one battery unit. The wireless terminal apparatus includes a wireless communication unit, a display unit, and a user interface. The wireless communication unit provides a wireless communication protocol to be wirelessly connected to the battery tester. The user interface is displayed on the display unit and operates an application program of the wireless terminal apparatus. The application program is executed by the wireless terminal apparatus to provide a test and monitor function to control the battery tester testing and monitoring the battery unit correspondingly connected to the battery tester. Accordingly, readability of the battery test results and convenience of monitoring and sharing the battery test results are increased.

Claims

1. A wireless battery management system configured for managing at least one battery unit, the wireless battery management system comprising:

at least one battery tester electrically connected to the at least one battery unit and configured to test and monitor the at least one battery unit; and

a wireless terminal apparatus comprising;

a wireless communication unit configured to provide a wireless communication protocol to be wirelessly connected to the at least one battery tester;

a display unit; and

a user interface displayed on the display unit and configured to operate an application program of the wireless terminal apparatus, wherein the application program is executed by the wireless terminal apparatus to provide a test and monitor function to control the at least one battery tester testing and monitoring the at least one battery unit correspondingly connected to the at least one battery tester.

2. The wireless battery management system as claimed in claim 1, wherein the application program further provides a record viewing function to view test result records of the at least one battery unit.

3. The wireless battery management system as claimed in claim 1, wherein the user interface is configured to provide multiple battery-testing parameter options including a battery type option, a battery rating option, and a battery capacity option.

4. The wireless battery management system as claimed in claim 1, further comprising:

at least one remote terminal device wirelessly connected to the wireless terminal apparatus and configured to provide a cloud service between the wireless terminal apparatus and the at least one remote terminal device.

5. The wireless battery management system as claimed in claim 1, wherein a topology of connection between the wireless terminal apparatus and the least one battery tester is a three-way handshaking topology.

6. The wireless battery management system as claimed in claim 1, wherein when the number of the at least one battery tester is plural, the battery testers are mutually connected to form a mesh topology;

when a firmware version or a parameter content of any one of the battery testers is updated, said battery tester is configured to update firmware versions or parameter contents of other battery testers.

7. The wireless battery management system as claimed in claim 1, wherein the wireless terminal apparatus is a personal computer, a notebook computer, a smart phone, or a tablet computer.

8. A method of operating a wireless battery management system that comprises:

at least one battery tester electrically connected to at least one battery unit and a wireless terminal apparatus having a wireless communication unit, a display unit, and a user interface displayed on the display unit and configured to operate an application program of the wireless terminal apparatus, and the application program executed by the wireless terminal apparatus to communicate with the at least one battery tester correspondingly connected to the at least one battery unit;

the method comprising steps of;

establishing a connection between the wireless terminal apparatus and the at least one battery tester;

controlling the at least one battery tester to execute a test and monitor function by the wireless terminal apparatus;

setting a battery testing parameter, a battery monitoring parameter, and battery tester monitoring data on the wireless terminal apparatus;

executing the test and monitor function by the wireless terminal apparatus; and

outputting testing and monitoring results from the wireless terminal apparatus.

9. The method as claimed in claim 8, after the step of establishing the connection between the wireless terminal apparatus and the at least one battery tester, further comprising steps of:

executing a record viewing function by the wireless terminal apparatus;

selecting a testing record and correspondingly producing a view selecting command by the wireless terminal apparatus; and

displaying the testing record according to the view selecting command by the wireless terminal apparatus.

10. The method as claimed in claim 9, after the step of executing the record viewing function, further comprising steps of:

selecting a cloud service and correspondingly producing a cloud selecting command; and

establishing a cloud connection between the wireless terminal apparatus and at least one remote terminal device and transmitting the testing record according to the cloud selecting command

11. The method as claimed in claim 8, wherein a topology of connection between the wireless terminal apparatus and the least one battery tester is a three-way handshaking topology.
