Description
Technical field
The present invention relates to accumulators, more specifically to the charging/discharging thereof and device of a kind of accumulator.
Background technology
Battery applications field is quite extensive, has application in numerous areas such as automobile, communication, railway, tractions.Currently,
Accumulator is mostly lead-acid accumulator, this is mainly due to lead-acid accumulator have technology maturation, at low cost, battery capacity it is big,
The advantages that following load good output and memory-less effect.Although in recent years the technology of accumulator itself have it is no small into
Step, but as provide chemical conversion for it and the development of charger that energy supplements again very slowly, there are charge and discharges for charging method
The defects of electric overlong time, rapid nitriding still fail to obtain effective solution, therefore current accumulator charging skill so far
Art cannot meet requirement of the accumulator using equipment such as equipment, such as electric vehicle well, this, which has become, influences accumulator development
Bottleneck.
In addition, since lead-acid accumulator comes out, due to the limitation of various technical conditions, used charging method is most
The rule for failing effectively to defer to internal storage battery physical-chemical reaction, make entire charging process there is serious overcharge and
Phenomena such as gassing, causes charge efficiency low.
Battery charger more universal at present is three stage charging system machine, and common three stage charging system machine has certain pair
Accumulator cell charging and discharging carries out the function of intelligent control, but the control of voltage and current when it is pertained only to charging, and has ignored
The considerations of to accumulator charging highly important ripple component.In battery characteristics parameter discrete, the string in face of equipment such as electric vehicles
When joining that lattice numbers is more and temperature influences the features such as big, common three stage charging system machine to the above-mentioned control method of accumulator cell charging and discharging,
The combined symptoms such as the presence for causing accumulator more or less overcharges, charge less, dehydration, vulcanization, unbalance, thermal runaway.
In addition, the pulse charge pattern of existing accumulator, using single direct impulse to accumulator in charge cycle
Charging, discharges to accumulator using single negative-going pulse in discharge cycle, when the charge volume of direct impulse is more than negative sense
When the discharge capacity of pulse, overall performance is to take electricity to charge the battery from power grid.On the contrary, if the charge volume of direct impulse is less than
When the discharge capacity of negative-going pulse, overall performance is that the electricity of accumulator is transported to power grid (being battery discharging).If desired
Quick charge is carried out to accumulator, it is necessary to larger charging current is used, under the pulse charge pattern of existing accumulator
Using larger charging current, the gassing for aggravating accumulator is reacted, and the active material on accumulator plate is largely taken off
It falls, shortens the service life of accumulator, and influence the effect of charging.
Invention content
The present invention, when carrying out quick charge to accumulator, will aggravate the analysis of accumulator for existing pulse charge method
Solid/liquid/gas reactions, and so that the active material on accumulator plate largely falls off, and shortens the service life of accumulator, and influence the effect of charging
The defect of fruit provides a kind of charging/discharging thereof and device of accumulator, and fast charging and discharging, and energy are carried out to accumulator by pulse
Enough gassing reactions for effectively slowing down accumulator.
The present invention solve its technical problem the technical solution adopted is that：
There is provided a kind of charging/discharging thereof of accumulator, required positive charge pulse and/or negative sense in the charge cycle
Charging pulse is equivalent pulse；The equivalent pulse is made of at least two burst pulses, and is wrapped between two adjacent burst pulses
Include time interval.
Optionally, all positive burst pulses of the burst pulse of the positive charge equivalent pulse.

Preferably, the shape of the burst pulse is rectangle, triangle or trapezoidal.
Preferably, the time interval is the equivalent time interval that burst pulse identical by shape, that direction is opposite is constituted.
Include being filled for providing the pulse of positive charge pulse the present invention also provides a kind of charge and discharge device of accumulator
The charging method of above-mentioned arbitrary scheme can be used in electric unit and the pulsed discharge unit for providing negatively charged pulse, the device.
The pulse charging/discharging thereof and device of the accumulator of the present invention have the advantages that：By narrow by multiple forward directions
Positive charge pulse made of pulse and multiple negative sense burst pulses are equivalent to charge the battery, and by narrow by multiple forward directions
Negative sense discharge pulse made of pulse and multiple negative sense public security impulse-equivalents is battery discharging, realizes the arteries and veins to accumulator
Charge and discharge are rushed, and when carrying out quick charge to accumulator using high current, can effectively slow down the gassing reaction of accumulator, prolong
The service life of long accumulator improves the effect of charging.
