This application claims priority to Taiwanese Patent Application No. 103140920 Nov. 26, 2014, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to a power supply system.
A power supply system in a notebook computer may be used to charge a battery.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
A definition that applies throughout this disclosure will now be presented.
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 term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.
The present disclosure is described in relation to a power supply system to charge a battery.
The detecting module 11 is configured to detect a working status of the computer, detect a capacity of the adaptor 20, determine whether the battery 30 exists, and detect the load 50. The working status of the computer comprises a normal status (S0 status) and a stand-by. The stand-by comprises a S3 status, a S4 status and a S5 status. The setting module 13 is configured to set a first reference value and a second reference value. The comparison module 15 is configured to compare the capacity of the adaptor 20 with the load 50. The comparison module 15 is also configured to compare the capacity of the adaptor 20 with a capacity of the battery 30. The control module 17 is configured to determine a supply status of the adaptor 20 and determine to supply power to the power supply according to the adaptor 20 and the load 50. The supply status of the adaptor 20 comprises a normal supply status, an electricity shortage status, and an abnormal supply status.
The control module 17 determines the adaptor 20 is normal supply when the capacity of the adaptor 20 is not less than the load 50, determines the adaptor 20 is electricity shortage when a difference value between the capacity of the adaptor 20 and the load 50 is not greater than the first reference value, and determines the adaptor 20 is abnormal supply when the difference value is greater than the first reference value and not less than the second reference value.
At block 101, the comparison module 15 determines whether the capacity of the adaptor 20 is not less than the load 50, if yes, the method goes to block 102; if no, the method goes to block 201.
At block 102, the detecting module 11 detects whether the battery 30 exists, if no, the method goes to block 103; if yes, the method goes to block 104.
At block 103, the control module 17 determines the adaptor 20 is normal supply and the power supply 40 supplies power to the load 50 via the adaptor 20.
At block 104, the comparison module 15 determines whether the capacity of the adaptor 20 is greater than the capacity of the battery 30, if no, the method goes to block 105; if yes, the method goes to block 106.
At block 105, the control module 17 determines the adaptor 20 is normal supply, controls the adaptor 20 to output a first charging current to charge the battery 30 when the computer is normal status, and controls the adaptor 20 to output a second charging current to charge the battery 30 when the computer is stand-by.
At block 106, the control module 17 determines the adaptor 20 is normal supply, the control module 17 controls the adaptor 20 to output the second charging current to charge the battery 30.
At block 201, the control module 17 determines whether the adaptor 20 is electricity shortage, if yes, the method goes to block 202; if no, the method goes to block 205.
At block 202, the detecting module 11 detects whether the battery 30 exists, if no, the method goes to block 203; if yes, the method goes to block 204.
At block 203, the control module 17 determines the adaptor 20 is electricity shortage and controls the power supply 40 to reduce power to the load 50.
At block 204, the control module 17 determines the adaptor 20 is electricity shortage, controls the adaptor 20 to output a third charging current to charge the battery 30 when the computer is normal status, and controls the adaptor 20 to output the second charging current to charge the battery 30 when the computer is stand-by.
At block 205, the detecting module 11 detects whether the battery 30 exists, if no, the method goes to block 206; if yes, the method goes to block 207.
At block 206, the control module 17 controls to turn off the computer.
At block 207, the control module 17 determines the adaptor 20 is abnormal supply and the battery 30 supplies power to the load 50.
At block 301, the comparison module 15 compares the capacity of the adaptor 20 with the load 50.
At block 302, the comparison module 15 determines whether the capacity of the adaptor 20 is not less than the load 50, if yes, the method goes to block 303; if no, the method goes to block 304.
At block 303, the control module 17 determines the adaptor 20 is normal supply.
At block 304, the comparison module 15 compares a difference value between the capacity of the adaptor 20 and the load 50 with the first reference value.
At block 305, the comparison module 15 determines whether the difference value is not greater than the first reference value, if yes, the method goes to block 306; if no, the method goes to block 307.
At block 306, the control module 17 determines the adaptor 20 is electricity shortage.
At block 307, the control module 17 determines the adaptor 20 is normal supply when the comparison module 15 determines the difference value is greater than the first reference value and is not less than the second reference value.
In the power supply system, the controller 10 compares the capacity of the adaptor 20 with the load 50 and outputs different charging current to supply power to the battery 30. In one embodiment, the second charging current is greater than the first charging current and the first charging current is greater than the third charging current.
It is to be understood that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, including in the matters of shape, size, and 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.
