Description
Technical field
The invention belongs to battery boosting technology, specially referring to a kind of pulse current charge mode charges, can realize that the adjustment of output pulse width carries out quick charge by rate of temperature change, can prevent the intelligent controller that overcharges or owe to fill of storage battery again, be applicable to the automation control of multiple battery charging equipment.
Background technology
By known to the known theory " seeing the research of accumulator charging method " in the enclosed accumulator charging process, inside produces oxygen and hydrogen, when oxygen can not in time be absorbed, just be deposited in positive plate, cell internal pressure is strengthened, battery temperature rises, dwindle the area of positive plate simultaneously, shown as internal resistance and rise, so-called polarization phenomena occurred, the serious more inside chemical composition that can damage battery more of polarization phenomena, thus the useful life and the capacity thereof of battery reduced.Charge for ensureing that battery can maintain under the poised state all the time, must make smaller as far as possible by the electric current of battery.Ideal conditions is the electromotive force that applied voltage equals battery itself.But practice shows that during charge in batteries, applied voltage must increase to certain numerical value, and this numerical value is because electrode material, the difference of various factorss such as solution concentration and surpassing the balance electric gesture value of storage battery in varying degrees.In chemical reaction, this electromotive force surpasses the phenomenon of thermodynamic equilibrium value, is exactly polarization phenomena.Produce polarization phenomena as can be known by principles well-known and be divided into three kinds, ohmic polarization, concentration polarization and electrochemical polarization wherein ohmic polarization are that storage battery produces hot main cause in charging process, and in charging process, negative ions moves to the two poles of the earth.In the ion transition process, be subjected to certain resistance inevitably, become ohmic internal resistance.In order to overcome this internal resistance, applied voltage just must additionally apply certain voltage, promotes the ion migration to overcome resistance.This voltage transforms to environment in the mode of heat, so-called ohmic polarization promptly occurs.Along with charging current sharply strengthens, ohmic polarization will cause the high temperature of storage battery in charging process.In order to make storage battery in charging process, reduce various polarization, many chargers have all been realized time-dependent current intermittent charge method, this method is improved on pulse charging method basis and is formed, this charging method is not only followed the intrinsic charge acceptance of storage battery, and can improve the charge in batteries receptance, thereby broken the restriction that curve is accepted in the charging of storage battery index.The pulse current charge mode at first uses pulse current to battery charge, allows battery stop filling a period of time then, progressively changes charging current according to the dynamic electric voltage situation of change of storage battery.So circulation becomes charging modes and is constant voltage charge behind the threshold voltage that is charged to the storage battery permission.Charging pulse makes storage battery charge into electric weight, and the intermittent phase makes storage battery regroup if having time and be absorbed through the oxygen of chemical reaction, concentration polarization and ohmic polarization are eliminated naturally, thereby alleviated the interior pressure of storage battery, intermittent pulse type is to charge in batteries, effectively fully the accumulators reaction time, reduce gassing rate, improved the charging current receptance of storage battery.Rise and fill end and carry out voltage sample yet adopt interval pulse to stop finishing end or interval pulse when adopting threshold voltage when judging charge in batteries of equipment that pulse makes charging usually, but the magnitude of voltage of adopting like this is often inaccurate towards the time.Reason is that intermittently the resultant voltage in back is non-steady state, resulting threshold voltage might be higher or lower than desirable threshold values under varying environment a lot, filled electric weight and the useful life that storage battery charges into thereby have influence on, simultaneously too early enters the charging interval that constant voltage charge can prolong storage battery again.Yet the temperature rising of being filled storage battery owing to the reason of ohmic polarization is more stable, it can not be subjected to pulse charging to play very big fluctuation because of changing pulse duration and amplitude, show that from test the temperature speed that raises and the voltage rising of being filled storage battery of being filled storage battery have very high comparativity, tangent (tag) the inverse function angle value of its variation of temperature rate almost is zero when the electric weight that is recharged the pond is sky, progressively increase along with being recharged the electric weight that the pond charged into, the tangent of its variation of temperature rate (tag) inverse function angle value also progressively strengthens, be filled electric weight gradually when being recharged the pond, the tangent of its variation of temperature rate (tag) inverse function angle value is also progressively near 90 degree.And present most of charging device just by observation be recharged the pond at the fixed time the elevated temperature (Δ T method) of section termination condition is used as charging, and the rate temperature change that will not be recharged the pond is controlled as the condition of charging process, each period of time T can be broken down into T=t1+t2+b in the pulse current charge process, be that pulse current charge is opened the stage wherein in the t1 time period, the t2+b time period is that pulse current charge closes the stage, t1 wherein, the variation of the ratio of t2 has determined the charge volume of pulse current charge, therefore will be recharged the rate temperature change and the t1 in pond, the ratio of t2 is set up a kind of corresponding relation, just can realize the condition control of charging process.
