Description
Technical field
The present invention relates to a kind of power supply of portable equipment, specifically is by using the intelligent extension power supply system that increases the portable equipment that external auxilliary battery expands under the prerequisite of main battery.
Background technology
Now in the life, the use of various electronic product portable equipments such as mobile phone, palmtop PC (PDA), portable electronic device (PMP) etc. more and more widely, and is especially essential especially under situation such as travel outdoors, commerce is consulted, often travelled on business trips.People wish can use these portable equipments whenever and wherever possible, present especially portable equipment function is various, as mobile phone, can listen to the music, play games, take pictures, see TV, online or the like, therefore battery has been had more higher requirements, the longer the better for stand-by time, portably uses convenient, flexible, replaceable battery is preferably realized hot plug certainly whenever and wherever possible.In the prior art, prolonging battery generally has following two kinds of methods service time: 1, adopt the electric core of maximum volume as far as possible, thicken battery; 2, improve assembly technology, adopt relatively thinner pole plate: battery capacity is relevant with active matter quality with the pole plate area, same volume, and thin more pole plate area is big more, and capacity is high more, and the pole plate high density is assembled to such an extent that the battery capacity made of thin more pole plate is high more.These two kinds of methods not only can increase the battery cost, and it is limited to increase electric weight, still can bring all inconvenience to the user.
In the prior art, the battery of electronic product portable equipment generally has two types, is example with the mobile phone:
1, the en-block construction at mobile phone rear portion all constitutes battery; 2, use small-sized inserted cell panel, there is a battery interface bottom surface of this cell panel, insert the power supply of cell panel relevant position on the matching with mobile phone and introduce spring card, thereby realize that cell panel contacts with the good of mobile phone internal structure, though this cell panel separates with cell phone rear cover, but if in use mobile phone falls accidentally, perhaps other reasons causes that temporary mobile phone power down can appear in dropping of internal cell plate or displacement, causes the instability of serviceability.If when using built-in main battery, use external auxilliary battery, dual guarantee then arranged.
Chinese patent Granted publication number discloses a kind of " how battery powered mobile phone " for CN2632970Y, referring to Fig. 1, it comprises body 10, charging jack 60, host circuit 80 and main battery 30, also comprise auxilliary battery 40, solar cell 20 and battery management circuit 70, described solar cell 20 is arranged on the shell of body 10, auxilliary battery 40 is arranged within the body 10, when main battery 30 capacity are used up, auxilliary battery 40 is devoted oneself to work, and can not interrupt communication, when the strong sunlight irradiation is arranged, devote oneself to work and disconnect the master by solar cell 20, auxilliary battery, with energy-conservation electric energy, give main simultaneously, auxilliary battery charge has made things convenient for people's use.
Referring to Fig. 2, the battery management circuit 70 of above-mentioned how battery powered mobile phone comprises battery intelligent control chip U90 and electronic switch U91-U96; The 9th of described chip U90,10,11 pin meet electronic switch U92, U93, the control end 2 of U94, electronic switch U92, U93, after being connected together, 3 pin of U94 connect host circuit 80 positive source incoming lines, 1 pin of electronic switch U92 connects the positive pole of main battery 30, the 13rd pin of chip U90 and 3 pin of electronic switch U91,1 pin of electronic switch U93 connects the positive pole of auxilliary battery 40, the 2nd pin of chip U90 and 1 pin of electronic switch U96,1 pin of electronic switch U94 connects the positive pole of solar cell 20, the 4th pin of chip U90 and 1 pin of electronic switch U95, the 15th pin of chip U90 connects the positive pole of charging jack 60, the end of resistance R 1 and R2 and 3 pin of U95,1 pin of another termination U91 of resistance R 1 and R2 and 3 pin of U91.
In working at ordinary times, whether the voltage of described chip U90 the 4th pin detection solar cell 20 is enough high, if enough high, just makes the 10th, 11 own pin output low levels, turn-offs U92, U93, only by solar cell 20 power supplies.If the voltage of solar cell 20 is not high enough, whether then described chip U90 the 13rd pin detects the capacity of main battery 30 enough, if enough, just makes the 10th, the 9 pin output low levels of itself, turn-offs U94, U93, only by main battery 30 power supplies.If main battery 30 capacity are not enough, described chip U90 the 11st, 9 pin output low levels are turn-offed U94, U92, change by auxilliary battery 40 power supplies.This moment, chip U90 the 2nd pin detected the voltage of auxilliary battery 40, and is low to also lower than main battery 30 if the capacity of auxilliary battery 40 is low excessively, then changes back to main battery 30 power supplies.
The voltage that detects solar cell 20 as fruit chip U90 the 4th pin rises enough highly, and that main battery 30, auxilliary battery 40 capacity fall is lower, and core U90 the 7th, 1,14 pin output high level be that main battery 30, auxilliary battery 40 charge by solar cell 20.
Detect charging jack 60 when charging voltage is arranged as fruit chip U90 the 15th pin, make the 7th pin output low level itself earlier, turn-off U95, judge that then main battery 30, auxilliary battery 40 which batteries need charging, if main battery 30 needs charging, just, connect U91, give main battery 30 chargings at chip U90 the 14th pin output high level.If auxilliary battery 40 needs charging, just, connect U96 at chip U90 the 1st pin output high level, give auxilliary battery 40 chargings.Give which battery charge, just which battery to give host circuit 80 power supplies by.
