The present disclosure relates to an apparatus for indicating power level of a battery in notebook computers.
A conventional notebook computer includes a chargeable battery which is attached to a bottom of the computer. The conventional notebook computer may not be able to indicate a battery level when the computer is shutdown.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
In the following description the term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected.
The battery module 30 includes a battery volume calculating chip 31, a temperature sensing unit 32, a first battery 33, and a second battery 34. The battery volume calculating chip 31 includes a first power level detecting pin 311, a second power level detecting pin 312, a data signal output pin 313, a clock signal output pin 314, and a second ground pin 315.
An anode of the first battery 33 is electrically coupled to the battery anode pin 211 and the first power level detecting pin 311 respectively. A cathode of the first battery 33 is electrically coupled to the second power level detecting pin 312 and an anode of the second battery 34 respectively. A cathode of the second battery 34 is electrically coupled to the first ground pin 215 and the second ground pin 315 respectively. The data signal output pin 313 is electrically coupled to the system management data pin 213. The clock signal output pin 314 is electrically coupled to the system management clock pin 214. The temperature detecting pin 212 is electrically coupled to the temperature sensing unit 32 and the first ground pin 215 respectively.
In at least one embodiment, the battery module 30 includes a liquid crystal display (LCD) panel (not shown). The battery volume calculating chip 31, the temperature sensing unit 32, the first battery 33, the second battery 34, and the pins in the slot 21 are interconnected by a number of system management buses (not shown). The temperature sensing unit 32 is located adjacent to the first battery 33 and the second battery 34.
In use, the first power level detecting pin 311 and the second power level detecting pin 312 detects power level information of the first battery 33 and the second battery 34 respectively. The battery volume calculating chip 31 calculates electricity quantities of the first battery 33 and the second battery 34 respectively according to the power level information. The battery volume calculating chip 31 transmits electricity quantities of the first battery 33 and the second battery 34 to the computer base 10 by the data signal output pin 313 and the clock signal output pin 314.
The temperature sensing unit 32 detects temperatures adjacent to the first battery 33 and the second battery 34 respectively. The temperature sensing unit 32 transmits temperatures of the first battery 33 and the second battery 34 to the computer base 10 via the temperature detecting pin 212. The computer base 10 displays electricity quantities and temperatures of the first battery 33 and the second battery 34 on the LCD panel of the battery module 30. The battery module 30 also displays pictures on the LCD panel as an extension display of the cover 20.
Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and the arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
