Abstract
A kind of DC electronic self- recoverage safeties to battery second protection.By constantly detecting electric current, voltage, battery temperature feedback signal of the battery in charge and discharge process; amplify to control the guard mode of battery by the comparing to feedback signal; protect battery in charge and discharge process from the infringement of overvoltage, under-voltage, overcurrent and overtemperature degree; the battery caused by battery overvoltage, overcurrent and overtemperature degree is avoided to scrap and blast; the battery life that under-voltage causes is reduced and scrapped; not only realize that battery recovers the normal function of battery into after protecting by recharged, while ensuring that using for battery is safe.
Description
Technical field
The present invention relates to a kind of safeties to battery second protection, especially from mistake in charge and discharge process
The infringement of voltage, under-voltage, overcurrent and overtemperature degree, realizes that battery passes through recharged extensive after entering protection
The DC electronic self- recoverage safeties of the normal function in telegram in reply pond.
Background technology
At present, known mobile phone, panel computer, the cells in notebook computer second protection scheme of being applied to has four
Kind, PTC, FUSE (three end fuses), BREAKER (breaker), protection IC and MOSFET.PTC should
Wide with scope, price is low, but its operating time of protection is slow, influenced by ambient temperature big, unstable, only has
There is overcurrent protection function；FUSE (three end fuses) belongs to disposable protection device, outside its need of work
With protection IC and peripheral components cooperating, relative big, the fusing after protection that takes up room recovers the work of battery
Make extremely difficult；BREAKER (breaker) is necessarily mounted on battery, and it is mechanical contact, it is vibrated after
Hit can occur, stability is poor, and applicability is small；Protection IC and MOSFET is the secondary guarantor being molded in recent years
Shield technology, realizes that defencive function needs outer with device, relative to take up room than larger.Currently there are no a
Function is complete, the second protection individuality IC devices of small volume.
The content of the invention
In order to overcome that existing battery second protection actuation time is slow, big, stability influenced by ambient temperature is poor,
Overcurrent protection function is few, to recovering the job very difficult of battery after battery protection inconvenience maintenance, protection, receiving
Can occur after vibration more than hit, component number and take up room relatively than larger deficiency, the present invention is provided
A kind of DC electronic self- recoverage safeties, the DC electronic self- recoverage safeties can not only be applied to mobile phone,
The second protection of panel computer, cells in notebook computer, and integrated small volume, completion overvoltage,
Under-voltage, overcurrent and super temperature protection function, after protection can by it is recharged can recover battery it is normal
Function.
The technical solution adopted for the present invention to solve the technical problems is：In the protection circuit, by comparing amplification
2, the 3 pin detection electric discharge overload current of device IC1-1,1 pin of comparison amplifier IC1-1 is through triode V2
Overload time delay, the 7 pin warp of comparison amplifier IC1-2 are realized with 5 pin of V1 control comparison amplifiers IC1-2
The Push And Release of triode V4 and V6 controlling switch pipes Q1；12, the 13 pin detection of comparison amplifier IC1-4
Discharge short electric current, 14 pin of comparison amplifier IC1-4 are through triode V4's and V6 controlling switch pipes Q1
Push And Release；9, the 10 pin detection electric discharge brownout voltage of comparison amplifier IC1-3, comparison amplifier IC1-3
8 pin through triode V3, V5 and V6 controlling switch pipe Q1 Push And Release, the Push And Release control of switching tube Q1
System electric discharge and protection.5, the 6 pin detection charging of comparison amplifier IC2-2 overcharges electric current, comparison amplifier IC2-2
7 pin through triode V8 and V7 controlling switch pipes Q2 Push And Release；2, the 3 of comparison amplifier IC2-1
Pin detects charging overcharged voltage, and 1 pin of comparison amplifier IC2-1 is through triode V8 and V7 controlling switch pipes
The Push And Release of Q2；9, the 10 pin detection battery excessive temperature of comparison amplifier IC2-3, comparison amplifier IC2-3
8 pin through triode V8 and V7 controlling switch pipes Q2 Push And Release, the Push And Release control of switching tube Q2 fills
Electricity and protection.Terminal 1,2 connects load and charging circuit, and terminal 3,4 connects battery positive and negative electrode.
The beneficial effects of the invention are as follows protecting battery in charge and discharge process from overvoltage, under-voltage, mistake
The infringement of electric current and overtemperature degree, it is to avoid because the battery that battery overvoltage, overcurrent and overtemperature degree cause scrap with
Blast, the battery life that under-voltage causes is reduced and scrapped, and not only realizes that battery passes through again after entering protection
Charge and recover the normal function of battery, while ensuring that using for battery is safe.
