Description
Technical field
The invention belongs to the power electronics manufacturing technology, relate in particular to a kind of self-adaptive tractive dynamic battery high-speed multi-stage charging system and charging method thereof.
Background technology
Domestic charging system at electrokinetic cell mostly is constant voltage or current-limiting charge mode greatly at present, or constant voltage and current limliting mixed charged mode.Adopt constant voltage charging method exist the charging interval long, charging capacity is not enough and the defective of excessive easy generation battery damage of the storage battery initial charge current of deep discharge or personal safety; Though the constant current charge mode charging interval can shorten dramatically, other shortcoming of constant voltage charging method is not overcome yet:
When being in the power battery charging of deep discharge state (over-discharge state), charging system should have identification and be recharged the ability that the pond is in the deep discharge state, and with the charge rate of 0.5-1C% to its slow charging, the voltage of battery is promoted gradually, up to reaching the breakover voltage that withdraws from the deep discharge state; This process is called the trickle charge stage.The power battery charging device that adopts constant voltage or current-limiting charge mode, no storage battery overdischarge identification is to being in the charge in batteries of over-discharge state, because initial charge current causes the physical damage of storage battery much larger than corresponding trickle electric current;
Charging system recognizes and is recharged that the deep discharge breakover voltage has been crossed in the pond or during to the power battery charging of regular picture, with corresponding high electric current electrokinetic cell is carried out high speed charging, make it in the short as far as possible time, to reach 95% high charge final voltage; This process is for filling the stage soon.Adopt constant voltage charging method,, cause the charging interval tediously long along with the rising charging current of cell voltage descends gradually;
When system detected the voltage that is recharged the pond and reached 95% high charge final voltage, system was from filling phase transition soon to the stage of overcharging.In the stage of overcharging, system will provide from the high electric current that fills the stage soon through dropping to the minimum electric current of setting gradually being recharged the pond; In case when system detects charging current less than a certain set point, think that battery has been charged to final power capacity.The stage that overcharges has great effect to the charging capacity that is recharged the pond and finally reaches; In the stage of overcharging, charging current descend the general who has surrendered to make effectively gradually to be recharged pond inner violent chemical reaction when filling the stage soon steady gradually, make that being recharged the inner issuable hydrogen or oxygen gas in pond when filling the stage soon is neutralized absorption gradually, thereby the useful life of battery is reason overcharge generation hydrogenolysis and shortening not, and remaining 5% electric weight is replenished, and charging capacity is able to effective consolidation.Employing current constant mode charging, the control measure that reduce charging current when battery tension reaches 95% high charge final voltage when if it's too late will cause storage battery generation hydrogenolysis, cause the battery shortening in useful life, cause the damage of battery when serious;
In the electrokinetic cell application of electric power system in support, charging system is articulated on the backup battery electric power system all the time, because the self discharge of inside battery, the capacity of battery will descend gradually, and charging system should have the ability of floating charge; When the voltage that detects the backup battery group is lower than set point, charging system will start automatically, according to backup battery capacity decline situation, select the corresponding charging stage automatically, reach maximum capacity again until backup battery;
Usually the final charging voltage of battery is with 25 ℃ of Temperature Scaling, yet electrokinetic cells such as plumbic acid have per unit battery compartment (every element cell lattice of lead-acid battery are 2V) is about 3.9 millivolts/℃ negative temperature coefficient, this physical characteristic means: if with constant voltage or current constant mode charging, when ambient temperature is higher, may cause accumulator super-charge, and when ambient temperature is low, will cause the result of charge in batteries deficiency.
