Background technology
Notebook computer is owing to carry cells in notebook computer, advantage with mobile use that desktop computer and all-in-one do not possess, after cell voltage reduces, connect electric main, AC adapter will charge the battery automatically by notebook computer, even if under situation without battery, the self discharge of inside battery also can make its voltage reduce and charging automatically, but, the charging times of Notebook Battery is hundreds of only, so the pattern of this self discharge and charging has automatically shortened the serviceable life of battery greatly.Certainly, the battery of pulling up notebook computer also can prolong its serviceable life, but be to use inconvenience, especially make it to have lost the effect of the uninterrupted power source of Notebook Battery, make notebook computer be equal to desktop computer, because 220V attaching plug plug in trouble or sudden power will obliterated datas even damaged the notebook computer hard disk, the advantage of notebook computer is all gone.
Summary of the invention
But but the purpose of this invention is to provide people's controlled charging notebook computer that a kind of manual control is charged, it both can manually be arranged to give automatically the Notebook Battery charge mode, can manually be arranged to not automatic charge mode again, but manual control recharges when the voltage of Notebook Battery drops to a certain degree, thereby significantly reduce charging times, the serviceable life of significant prolongation Notebook Battery.
To achieve these goals, the present invention comprises power supply adaptor, the battery interface of notebook computer and the interface of Notebook Battery interconnect with plug connector, are in series with on the circuit to the Notebook Battery charging of the battery interface front of notebook computer and discharge and recharge the manual control circuit.
In order to simplify circuit, discharging and recharging the manual control circuit can be made of diode and switch in parallel.
Discharge and recharge the manual control circuit owing to connected on the circuit to the Notebook Battery charging of the present invention before the battery interface of known notebook computer, thereby can whether charge by the manual control notebook computer to Notebook Battery, the Notebook Battery that has overcome known technology just reduces the defective that frequently charges the battery and shorten its serviceable life that charging automatically causes as long as voltage has slightly, but in the serviceable life of the present invention's significant prolongation Notebook Battery, also overcome with the battery of pulling up notebook computer and prolonged the uninterrupted power source effect that loses Notebook Battery that its life-span brings and the defective of trouble.
Embodiment
In the drawings, power supply adaptor 6 is pegged graft mutually by the supply hub of attaching plug and notebook computer 1, the battery interface of notebook computer 1 has 6 splicing ears, and (with the nc8000 of Hewlett-Packard notebook computer is example, this splicing ear quantity of the notebook computer of different brands and model is not necessarily identical), 2 of the outermost of these 6 splicing ears are splicing ear 4,5, and wherein splicing ear 5,4 is respectively anodal and ground.Corresponding Notebook Battery 2 also has 6 splicing ears, its ceiling voltage terminal+, ground terminal-.5 of these 6 groups of splicing ears directly have been connected with each other notebook computer 1 and Notebook Battery 2 with connector 3.Be connected on the internal circuit of the 6th group of splicing ear 5 after K switch and the diode D parallel connection, K switch should be installed in the side or the bottom surface of notebook computer 1 shell, to make things convenient for manual shift.K switch and diode D formation in parallel discharges and recharges the manual control circuit.If be connected on the internal wiring of splicing ear 4 discharging and recharging the manual control circuit, effect is the same, but this moment, diode D polarity was wanted reversal connection.The notebook host part that the part that frame of broken lines is got up among the figure is integrated that is to say to discharge and recharge the manual control circuit and notebook host is incorporate.
The course of work of present embodiment is as follows: after K switch is manually connected, just be equivalent to the function and the process of known notebook computer, notebook computer 1 discharges and recharges (charging requirement energized adapter 6 and civil power thereof) for automatically Notebook Battery 2; After K switch manually disconnects, because the reverse access of diode D, notebook computer 1 is (this should be the situation of the most normal use of family expenses or office notebook computer) that can't charge to Notebook Battery 2, when the process a very long time, Notebook Battery 2 self discharges or use Notebook Battery are after 2 work a period of times, and the laptop electric power management software shows that electricity is not enough and near under 10% the situation, manually connect K switch again and charge automatically, being full of behind the electricity again, cut-off switch K gets final product.Like this, be well suited for notebook computer and be placed on main situation in family or the office, can reduce to Notebook Battery 2 automatic charging times and more than tens times, prolong the actual life of Notebook Battery 2 greatly with electric main.This is also than good many of the common battery life prolonging method of pulling up notebook computer, one is to use conveniently and does not influence the outward appearance of notebook computer, the 2nd, in case get loose or have a power failure because of the 220V plug, it is notebook computer 1 power supply that Notebook Battery 2 can continue by diode D, has played the effect of uninterrupted power source.In addition, the output voltage of Notebook Battery 2 drops to and to a certain degree recharges is reasonably practical, there is no need Notebook Battery voltage fully and drops to 90% even above with regard to charging automatically.Need under the situation of long period with Notebook Battery 2 power supplies when some day, can in advance the K switch connection be full of electricity and re-use.Said process of the present invention has obviously reduced the charging times of Notebook Battery 2 significantly and has not influenced the function and the effect of original Notebook Battery.Because of Notebook Battery 2 discharge and recharge number of times also with regard to hundreds of time, so the present invention can prolong the serviceable life of Notebook Battery greatly, but cost does not almost improve.
Because the access of diode D, the voltage that makes Notebook Battery 2 send into notebook computer 1 reduces about 0.2V, but this is just using the 220V electric main without Notebook Battery 2, only Notebook Battery 2 as under the standby uninterrupted power source operating position, the true K switch of can manually connecting when powering with Notebook Battery 2 is not so can influence the original service efficiency and the effect of battery.
For reduce diode D divide voltage, what the diode D of present embodiment will be with the semiconductor Germanium material, rated current is greater than 2A.Notebook Battery 2 and notebook computer 1 usefulness are just original, but will draw two lines that connect K switch on the mainboard of notebook computer 1.K switch keys available or plug-type,
The invention is not restricted to the foregoing description, such as: discharge and recharge the manual control circuit also available electron chemical control system circuit replace, but its switch still want manually-operated just can, switch at this moment can be with microswitch or soft-touch control.Can directly design, but these variations all do not depart from essence of the present invention discharging and recharging the manual control circuit in main board for notebook computer inside or the like yet.
