Description
Technical field
The present invention relates to a kind of batter life extender, relate in particular to a kind of batter life extender that is applied on the sealed lead acid storage battery.
Background technology
Phenomenons such as lead-acid battery ubiquity inside battery self discharge, because after there is little electric current self discharge for a long time in inside battery, will produce tiny lead sulfate crystal (annotate: tiny lead sulfate crystal is the invertibity material) on the inside battery pole plate, if but these tiny lead sulfate crystal are not handled timely, will cause large tracts of land lead sulfate crystal, being commonly called as " sulfuration ". large-area sulfuration crystal is carried out on battery pole plates, form barrier and block the pole plate hole, make electrolyte infiltration difficulty and increased the internal resistance of cell, battery capacity is obviously descended, even can cause the battery necrosis.
Also there are some similar products like to occur in the market, but major part all will rely on external power source (civil power) that working power is provided or be hardened to purpose to battery charging and discharging to reach the inhibition lead sulfate by artificial timing, this brings very big inconvenience to the user undoubtedly, also can bring certain potential safety hazard simultaneously.
Summary of the invention
The above-mentioned characteristic that the present invention is directed to lead-acid battery designs, by the auto monitoring and measurement circuit storage battery is discharged and recharged effectively, in time suppress lead sulfate crystallization and the diffusion that lead-acid battery produces because of self discharge, again be converted into the reversible lead sulfate that crystal is tiny, chemical property is high to reach the lead sulfate crystal, make battery maintain impulse electricity performance efficiently in a long time, prolong the battery purpose in useful life thereby reach.
In order to achieve the above object, the invention provides a kind of batter life extender that is used for lead acid accumulator, be connected in series in current circuit with storage battery, this batter life extender comprises:
Intelligent switch, circuit connects storage battery;
Voltage stabilizing circuit connects the both positive and negative polarity of described storage battery by described intelligent switch circuit;
Frequency conversion inverter circuit, circuit connect described voltage stabilizing circuit;
Impulse circuit, circuit connect the both positive and negative polarity of described frequency conversion inverter circuit and storage battery;
Energy-conservation timer, circuit connect described accumulator anode and cathode and intelligent switch;
Energy-conservation timer reads battery tension and picks up counting, and the supervision storage battery moment electric weight of depositing, if the cell voltage surplus is low excessively, be that the alarm user in time mends to battery, after timer reached the scheduled time, energy-conservation timer sent a clock signal and gives intelligent switch, makes intelligent switch closure (switch is in open-circuit condition under the normality), voltage stabilizing circuit is got battery feed and is entered the voltage stabilizing operating state, for back level frequency conversion inverter circuit provides stable working power; The frequency conversion inverter circuit comprises accumulator, inversion step-up circuit and PWM (the Pulse Width Modulation pulse-width modulation) circuit that circuit connects, according to the stored energy of battery capacity size decision accumulator and the duty ratio of PWM, by pwm circuit control inversion step-up circuit low pressure is boosted again, and high pressure outputed to impulse circuit, finish frequency conversion inversion process; Impulse circuit directly is transferred to storage battery again with this high-voltage pulse again, and acts on storage battery advance directed current limliting processing by the high voltage pulse after boosting, and removes the sulfide on the internal storage battery pole plate, makes storage battery keep active.
The present invention adopts battery self power supply energy regularly to carry out impulse electricity to battery, be exclusively used in the lead-acid battery regular maintenance and maintain to reach the purpose that storage battery is lengthened the life and economized on electricity, the present invention can follow according to the battery capacity size and adjust the correlation technique parameter, adopt the auto monitoring and measurement circuit that battery is discharged and recharged effectively, in time suppress lead sulfate crystal deposition, sclerosis and diffusion that lead-acid battery produces because of self discharge, thereby make the lead sulfate crystal be converted into the reversible lead sulfate that crystal is tiny, chemical property is high again.
