While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred embodiment with the understanding that the present disclosure is to be considered an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated.
Please refer to the FIG. 2 and FIG. 3. A method of detection and display of charging information of power bank is provided by the present invention. The method of detection and display of charging information of power bank is used when a mobile electronic device 4 is charged by a power bank 3 via a charging transmission device 5, and the method includes following step:
An Information Acquisition Step S1:
Please refer to FIG. 3A and FIG. 3B. The information acquisition step S1 provides at least a power bank parameter information 331 of the power bank 3 and at least a device parameter information 431 of mobile electronic device 4 are pre-determined (for example: based on a user's choice), and the power bank parameter information 331 and the device parameter information 431 are transmitted to a computing module 411 of a process unit 41 of the mobile electronic device 4.
The power bank parameter information 331 is saved in the first storage unit 33 of the power bank 3. The power bank 3 further includes a control unit 31 and a battery module 32. The control unit 31 is electrically connected to the battery module 32 and the first storage unit 33. In detail, the battery module 32 is a recharge battery configured for saving energy and charging the mobile electronic device 4, and the recharge battery is such as Li-ion battery, Li-polymer battery, or Ni-MH battery. The first storage unit 33 is a flash memory or other non-volatile memory. Moreover, the power bank parameter information 331 is the information about the battery module 32, for example: battery capacity, remaining power, charging current, temperature, or product serial number, etc. In addition, the control unit 3 and other elements (such as temperature sensor or power manage chip) for generating the power bank parameter information 331 are understood by a person having ordinary skill in the art, so they are not explained in detail in the present invention.
The charging transmission device 5 is such as a charging transmission lines or a wireless charging device. Therefore, the power bank 3 can charge or exchange information with the mobile electronic device 4. In this embodiment, the charging transmission device 5 is a USB line. The detail structure and the principle of the wireless charging device is prior art, so it would not be explained in detail hereinafter. The mobile electronic device 4 is a smart phone or a tablet PC. The device parameter information 431 is saved in the second storage unit 43 of the mobile electronic device 4. The mobile electronic device 4 further includes a recharging battery 42 and an input/output element 44. The process unit 41 is electrically connected to recharging battery 42, the second storage unit 43, and input/output element 44. The recharge batter 42 is Li-ion battery, Li-polymer battery, or Ni-MH battery. The second storage unit 43 is a flash memory or other non-volatile memory. The input/output element 44 is a touch screen, but in other embodiment the input/output element 44 also can be composed of an individual keyboard and screen. The device parameter information 431 is information about the recharging battery 42 of mobile electronic device 4, for example: battery capacity, remaining power, or type of the mobile electronic device 4, etc. Moreover, the computing module 411 is a special circuit module or an application (APP), it is configured to provide a operation interface in the input/output element 44. Therefore, the computing module 441 can acquire the power bank parameter information 331 and the device parameter information 431 from the operation interface based on the operation commanding selected or inputted by the user.
An Integrating and Computing Step S2:
A charging information is produced after the power bank parameter information 331 and the device parameter information 431 acquired in the information acquisition step S1 are integrated or computed.
In this step, the charging information means the remaining charging time (how many charging times the power bank 3 has), the current temperature of the mobile electronic device 4, the current temperature of the power bank 3, the impedance of the charging transmission line (over-high impedance represents the charging transmission line is abnormal), etc. The above said computing includes one or all of the following method: sifting of information, the logic determining of condition, or the computing of value. In this embodiment, the charging information is the remaining charging times. In this moment, the power bank parameter information 331 is the real remaining power of the battery module 32 (such as 6000 mAh), and the device parameter information 431 is battery capacity and remaining power of the battery module 42 (such as 2000 mAh and 1000 mAh). Therefore, the computing module 411 can produce the charging information after the computing module 411 integrates and computes the above said information. Therefore, the remaining charging time is 3.5 times computed by following equation:

1+(6000−1000)÷2000=3.5

An Information Output Step S3:

Please refer FIG. 3C. The charging information produced in the integration and computing step S2 is transmitted and displayed on the input/output element 44 of the mobile electronic device 4. In this embodiment, a message “remaining charging times: 3.5” would be displayed on the touch screen of the mobile electronic device 4. Therefore, the method of detection and display of charging information of power bank is completed.
Furthermore, if the mobile electronic device 4 has speech output function, the charging information can be played via the speech output function. Thus, the convenience of the present invention can be effectively increased.
Please refer the FIG. 2 and the FIG. 3. The user can browse the useful charging information such as remaining charging times when the phone is charged by the power bank 3. The user can understand the state of the power bank, so the user can charge the power bank charged when the power of the power bank is not enough, and the power bank and mobile electronic products both out charged can be avoided. Thus, the practicality and the convenience of the power bank can be effectively increased in the present invention.
Please refer the FIG. 4. FIG. 4 shows the second embodiment of the present invention. The charging information is also transmitted to an external server 6 by the computing module 41 via a wireless communication module 46 (such as Bluetooth module, Wi-Fi module, or 3G mobile internet module) of the mobile electronic device 4. For example: the charging information is product serial number of the power bank 3. Therefore, the power bank 3 can be automatically registered when the mobile electronic device is charged by power bank 3. Moreover, the user also can download the instructions and other information from the server 6, and the user does not need to register by hand or save other warranty document. Thus, the after sale service and added value of the power bank 3 can be effectively improved in the present invention.
