Description

The notebook computer portable power supplies
Technical field
The utility model relates to a kind of laptop electric power.
Background technology
Existing notebook computer generally adopts lithium battery power supply, and there is following drawback in it:
One, because charging and discharging lithium battery needs accurate protective circuit, the production technology more complicated, thereby the production cost of lithium ion battery is higher, an original-pack lithium battery price is wanted nearly 1,000 yuan;
Two, lithium battery capacity is little, cruising time is short, generally can only use 2-3 hour, if be equipped with one again, not only cost height, and two batteries is added up also can only be provided about about 5 hours cruising time, and this is far from being enough to the people who often goes on business, and lithium battery generally through after 300~500 times the charging repeatedly, just can filled.Along with the lithium battery increase of service life, it can be supplied to the stand-by time meeting of notebook computer shorter and shorter, uses the lithium battery that surpasses 3 years most only about 1 hour as the stand-by time that notebook computer provided;
Three, battery needs to guarantee the convenience of the work of going out as the important step of notebook computer portable performance.The notebook computer lithium battery is that lithium cell and circuit are added the shell encapsulation, and weight is bigger; Not only weight is big if carry power supply adaptor, and takes up room, and these all are very big burden concerning the people who often goes on business.
The utility model content
The purpose of this utility model is to adopt lithium battery power supply cost height, cruising time is short, weight is big problem in order to solve existing notebook computer, and a kind of notebook computer portable power supplies is provided.
The utility model is made up of cathode power supply line, anode power cord, battery case and nickel-hydrogen chargeable cell group, the cathode output end of battery case connects an end of cathode power supply line, the cathode output end of battery case connects an end of anode power cord, the electrode input end of battery case connects the positive pole of nickel-hydrogen chargeable cell group, and the negative input of battery case connects the negative pole of nickel-hydrogen chargeable cell group.
Described notebook computer portable power supplies, the nickel-hydrogen chargeable cell group by every joint capacity be the 2000-3000 MAH at least two the joint nickel-hydrogen chargeable cells form.
The utility model has the advantages that:
The utility model adopts cheap nickel-hydrogen chargeable cell to replace lithium battery, need not encapsulate separately, more over half than using lithium battery can reduce cost approximately, being equipped with two cover nickel-hydrogen chargeable cells in use simultaneously is the notebook computer power supply, the cancellation power supply adaptor, it is about more than 2/3rds further to reduce the supplying cell cost.
Existing notebook computer is generally 4000-4800mAh with the capacity of lithium battery, approximately can use 2-3 hour, capacity with every joint nickel-hydrogen chargeable cell is that 2500mAh calculates, when nickel-hydrogen chargeable cell is two joints, total capacity is just greater than the capacity of lithium battery, but power-on time is about 1.2 times of lithium battery, select the big capacity nickel-hydrogen chargeable cell of more piece for use, then can prolong the cruising time of notebook computer greatly, be equipped with two cover batteries simultaneously and charge respectively, power, can make notebook computer not have to accomplish round-the-clock use under the situation of circumscripted power line.
Being equipped with two cover nickel-hydrogen chargeable cells simultaneously is the notebook computer power supply, replaces the power supply adaptor of former notebook computer, has reduced the total weight and the volume of notebook computer, and the travelling weight of notebook computer is reduced more than 500 grams, and convenient trip is carried.
Description of drawings
Fig. 1 is that the utility model nickel-hydrogen chargeable cell is the structural representation in 6 whens joint, and Fig. 2 is the circuit theory diagrams of 6 joint nickel-hydrogen chargeable cell series-feds among Fig. 1.
Embodiment
Embodiment one: present embodiment is described below in conjunction with Fig. 1 and Fig. 2, present embodiment is by cathode power supply line 1, anode power cord 2, battery case 3 and nickel-hydrogen chargeable cell group 4 are formed, the cathode output end of battery case 3 connects an end of cathode power supply line 1, the other end of cathode power supply line 1 connects the positive pole of cells in notebook computer interface, the cathode output end of battery case 3 connects an end of anode power cord 2, the other end of anode power cord 2 connects the negative pole of cells in notebook computer interface, the electrode input end of battery case 3 connects the positive pole of nickel-hydrogen chargeable cell group 4, and the negative input of battery case 3 connects the negative pole of nickel-hydrogen chargeable cell group 4.Multiple batteries in the nickel-hydrogen chargeable cell group 4 can guarantee that output voltage is identical with lithium battery by the mode of series, parallel or string and series-parallel connection.
