The battery assembly 11 is electrically connected to the controller 12, and the battery assembly 11 generates battery data when the CPU of the electronic device E is not in operation. Specifically, the battery assembly 11 comprises a battery and an integrated circuit (IC) which are electrically connected to each other, wherein the integrated circuit obtains the battery data from the battery, and the integrated circuit sends the battery data to the controller 12. For example, the integrated circuit may be a power management integrated circuit (PMIC), and the battery may be the rechargeable (or the secondary battery) battery such as the lead acid battery, the nickel hydrogen battery or the lithium ion battery, this disclosure is not limited thereto. On the other hand, aforementioned “the CPU not in the operation” means that the operating system (OS) of the electronic device E is not active, which indicates that the system power states (S-States) is in one of S1 (sleep state) through S5 (soft off state).
The controller 12 is electrically connected to the battery assembly 11, wherein the controller 12 receives the battery data from the battery assembly 11 and generates battery information according to the battery data. Specifically, the battery data may comprise the information of the battery assembly 11, such as original battery capacity, times of charging, current battery power, current voltage and charging electric current. Additionally, the battery information may comprise the current information of the battery assembly 11, such as the state of charges/discharges, total numbers of charges/discharges, current battery power during charging, or the remaining battery power, etc. It is worth to mention that, the battery information is able to be the data providing a plurality of functions through a software interface, such as generating a warning message for overcharge or the abnormal current as the battery assembly 11 is charging, estimating the usage time based on the remaining battery power of the battery assembly 11, and estimating the efficiency of charge and outputting the graph or table associated with the battery assembly 11. It needs to be noticed that, this disclosure is not limited thereto. In practice, the controller 12 may be implemented by an embedded controller 12 (EC), and the controller 12 is able to receive the battery data as the battery of the battery assembly 11 is keeping to be electrically connected to the controller 12.
The wireless transmission assembly 13 is electrically connected to the controller 12. The wireless transmission assembly 13 receives the battery information from the controller 12 and sends the battery information to the software interface of the portable device P, wherein the electric power of the wireless transmission assembly 13 is supplied by the battery assembly 11. In an embodiment, the wireless transmission assembly 13 is a Bluetooth low energy (BLE) transmission assembly, but other embodiments are not limited thereto. For example, the communication protocol of the wireless transmission assembly 13 also may be the Bluetooth or the wireless network. Specifically, the Bluetooth low energy is more efficient in power saving than the Bluetooth, and the process for communicatively connection to the electronic device E is simpler than the wireless network. For these reasons, the Bluetooth low energy may be preferable to be used in the device disclosed in this disclosure.

Please refer to the step S6 to S8 for descripting how the software interface determines a health state of the battery assembly. Please refer to the step S6: determining whether the ratio between the current maximum battery power value and the default battery power value is inside the abnormal range by the software interface, wherein the current maximum battery power value and the default battery power value may be obtained by the software interface according to the battery information. When the software interface determines the ratio is outside the abnormal range, please refer to the step S7: determining the health state of the battery assembly as in the normal state by the software interface; wherein the normal state indicates the battery assembly is able to work and supply electric power in a proper way. When the software interface determines that the ratio is in the abnormal range, please refer to the step S8: determining the health state of the battery assembly as in the abnormal state by the software interface. Since the abnormal state indicates the current maximum battery power value of the battery assembly is too low, the software interface can generate aforementioned warning signal to prompting the user to replace the battery.

The light-emitting assembly 14 is electrically connected to the controller 12, wherein the light-emitting assembly 14 generates light when receives the battery information from the controller 12. Moreover, the light-emitting assembly 14 changes an optical characteristic of the light when receives a control signal from the controller 12, wherein the control signal is generated after the controller 12 is triggered by the software interface.
Specifically, after the controller 12 generates the battery information according to the battery data, the light-emitting assembly 14 is able to generate the light according to the battery information at least, and the light-emitting assembly 14 displays the battery information based on the optical characteristics corresponding to different situations. For example, as the battery information is the current battery power value, the controller 12 is able to control the light-emitting assembly 14 to generate red light (indicating low battery power) or yellow light (indicating normal battery power) according to different current battery power values. Hence, the battery assembly 11 is able to show different current battery power values through generating the light with different optical characteristics.
In another embodiment, after the controller 12 sends the battery information to the light-emitting assembly 14, the software interface is able to trigger the controller 12 to send the control signal to the light-emitting assembly 14, wherein the control signal is associated with the optical characteristic of the light generated by the light-emitting assembly 14. Specifically, when the user adjusts the optical characteristic through the software interface, the software interface is able to trigger the controller 12 to send the control signal to the light-emitting assembly 14. For example, the control signal can change the yellow light indicating normal battery power to green light. Alternatively, as the red light indicating to low battery power is flashing, the control signal can change the flashing frequency of the red light. For these reasons, the user can adjust the optical characteristic of the light generated by the light-emitting assembly 14 through the software interface by themselves, and the variety of user experience can be provided.
