Description
Affiliated technical field
The utility model relates to a kind of lead acid accumulator electronic protector, especially automatically the lead acid accumulator multi-function protector of control impuls frequency.
Background technology
Lead acid accumulator is a kind of charging accumulator that generally uses, because the design feature such as the long-term improper use overdischarge of this battery or overcharge, and do not use for a long time and do not charge etc., on pole plate, form the sulfuration crystal easily, make the charging and the discharging efficiency decline of lead acid accumulator and shortened useful life.In order to prolong the useful life of lead acid accumulator, people have adopted the method for many chemistry and physics, comprising utilizing the electronic impulse technology to prevent and reducing sulfation.
The at present known electronic circuit of removing lead acid batteries electrode plate sulfide with electronic impulse, its cardinal principle is that storage battery is powered to electronic switching circuit, produce a frequency of oscillation, frequency of oscillation makes switching circuit produce pulse voltage to inductance, and with this pulse voltage long term in the positive and negative electrode of lead acid accumulator, lead acid accumulator prevented and reduce the sulfuration crystalline polamer.Now foregoing circuit is analyzed and found to have two weak points: the one, lead acid accumulator in use voltage is in variable condition, be that 12 volts storage battery is an example now with voltage, when being full of, electricity is 12.8 volts, drop to 10.8 volts after the use, and above-mentioned impulse circuit produces is a kind of fixed frequency pulse, can not obtain optimum efficiency at the cell voltage that changes; The 2nd, above-mentioned impulse circuit is connected in parallel on the lead-acid battery electrode for a long time, and itself needs consumed power impulse circuit, will not make battery be in over-discharge state if battery a period of time charges.
In order to prevent the damage lead acid accumulator that overcharges, have anti-overshoot electricity special charger at present, and this special charger complex structure price is expensive simultaneously, some units often adopt simple charger by the labor management charging; Lead acid accumulator in use simply relies on and manually is difficult to prevent overdischarge on the other hand, so people have consumed a lot of energy in the process of using lead acid accumulator.
Summary of the invention
In order to overcome the above-mentioned at present known deficiency and the inconvenience of using lead acid accumulator to bring of removing the electronic circuit of lead acid batteries electrode plate sulfide with electronic impulse to people; the utility model provides a kind of lead acid accumulator multi-function protector of automatic control impuls frequency, can reduce the sulfuration crystal effectively and lead acid accumulator is caused the adverse consequences that capacity descends and prevent from automatically to overcharge and overdischarge.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with the multipoint oscillation circuit in the circuit of this protector, its frequency of oscillation can just change by the multipoint voltage frequency dividing circuit according to battery tension and change frequency of oscillation automatically, also changed simultaneously the pulse output frequency, to obtain the effect of better removal sulfuration crystal; Also be provided with the under-voltage protection circuit in the multipoint voltage frequency dividing circuit in this protector, the failure of oscillations of this protector oscillating circuit makes it the no-output pulse to reduce the current drain of storage battery when lead acid accumulator is in low-voltage state; Simultaneously in order effectively to prevent overcharge of a battery and overdischarge; in this protector, be provided with the electronic switching circuit that prevents from automatically to overcharge with overdischarge; when lead acid accumulator the time overcharges or normal when using the generation overdischarge in charging; can both disconnect the circuit that lead acid accumulator connects with charger or electrical appliance timely and effectively; and the light-emitting caution state prevents from automatically that overcharging from appearring in storage battery to make the adverse consequences that become with overdischarge.
The beneficial effects of the utility model are: the simple and practical property of lead acid accumulator multi-function protector of control impuls frequency is strong automatically; after the positive and negative electrode of this device and lead acid accumulator correctly connected, can reach lead acid accumulator increase capacity, life-saving, minimizing fault, purpose easy to use.
