Abstract
The present invention discloses a charge method for motor vehicle accumulator chargers. The accumulator is firstly charged via a constant current of about 1.8A to 43.2V (14.4V/battery) and is secondly charged via constant voltage, so the current is gradually reduced, and the voltage is gradually increased until about 44.1 to 44.5V. When the current is reduced to 1.2 (+/-) 0.1A, timing is started, and limiting charging time t is 3 hours. The present invention has the determining method for high voltage limiting charging time t that an accumulator with a little larger capacity is discharged to 10.5V/ battery, and then the accumulator is charged via a method of constant voltage 14.8V/ battery and current limiting 1.8A. The change of charging voltage and current is recorded, so the time t of the current reducing from 1.2A to an exchange current (0.35 to 0.40A) is calculated in 2.5 to 2.75 hours. In order to ensuring full charge, the determinate hour t is 3 hours so as to efficiently solve the maximum defect of original common three-section type chargers.
Description
Technical field
The present invention relates to charger charging method field, relate in particular to a kind of charging method of electromobile battery charger.
Background technology
(with 36V10AH is example in common syllogic charging, charging curve is seen accompanying drawing 1), the electric current constant current charge of beginning about with 1.8A is to 43.2V (14.4/ on each battery), enter constant voltage charge, electric current progressively reduces, and voltage progressively rises to 44.1～44.5V, is transformed into floating charge when electric current is reduced to 0.35～0.40A, voltage 41.4～42V constant voltage charge is up to taking off charger (or cutting off the charging power supply), and the charging interval majority was at 8～12 hours.Charging capacity be last time discharge capacity 104～110%, experiment shows that the lead acid storage battery cell voltage begins to have minimum gas to separate out from about 14.0V, accelerate to 14.4V gas speed of separating out, there is more gas to separate out to 14.8V, main bubbing is (the 14.4V charging rises to the 14.8V time about about 30min) after the 14.8V, thereby effectively control well high voltage region time promptly effectively separating out of control gaseous reduce fluid loss, reduce heating, faults such as distortion.
Because storage battery is in charge and discharge process, electrolyte in the storage battery reduces gradually, the oxygen cycle recombination current strengthens, and anodal part harmful element is deposited to negative pole and has reduced gas and separate out overpotential, and can be subjected to the influence that battery temp increases, the electric current in latter stage of charging is strengthened gradually, there is part storage battery may occur charging latter stage electric current to surpass 0.35～0.40A (switching current), makes charging not be transformed into the floating charge stage (not changeing green light), charge with high voltage always, cause in a large number and overcharge, separate out a large amount of gases, strengthen fluid loss, make storage battery that " thermal runaway " take place, faults such as distortion, these faults are especially serious when high temperature.
Summary of the invention
The object of the present invention is to provide a kind of high voltage time limit charging method, solved the greatest drawback of former common three-step charger: it is " not changeing green light " phenomenon that charging is not transformed into the floating charge stage, and faults such as " thermal runaway ", distortion take place easily.
In order to solve existing problem in the background technology, the present invention adopts following technical scheme:
A kind of high voltage time limit charging method: begin with the electric current constant current charge about 1.8A to 43.2V, it is each battery 14.4V/, enter constant voltage charge, electric current gradually reduces, voltage rises gradually, to about 44.1～44.5V, when electric current reduces to 1.2 ± 0.1A, pick up counting, restriction charging interval t is 3 hours.Definite method of a kind of restriction charging interval t of high voltage time limit charging method: at first by test, the storage battery that the amount of trying to please is bigger, with battery discharging only to 10.5V/, use constant voltage 14.8V/ only again, the method of current limliting 1.8A is charged, and the record charging voltage and current changes, and calculates electric current and is reduced to the time t1 of switching current 0.35～0.40A in 2.5～2.75 hours from 1.2A, for guaranteeing full charge, determined restriction charging interval t gets 3 hours for good.
Therefore, the present invention is actual to be to increase " insurance " together on the basis of original charger, efficiently solve and formerly charge with high voltage always, cause in a large number and overcharge, separate out a large amount of gases, strengthen fluid loss, make storage battery that " thermal runaway " take place, faults such as distortion reduce unusual dehydration of storage battery and heating distortion greatly, can not influence the charging degree of saturation.

Fig. 2: the charging curve of prescribing a time limit of the high voltage in the embodiment of the invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described by specific embodiment.
Embodiment: with 36V10AH is example, charging curve is seen accompanying drawing 2, the electric current constant current charge of beginning about with 1.8A is to 43.2V (each battery 14.4V/ only), enter constant voltage charge, electric current gradually reduces, voltage rises gradually, to about 44.1～44.5V, when electric current reduces to 1.2 ± 0.1A, pick up counting, restriction charging interval t (being generally about 3h), charge in limited time definite method of binding hours t of high voltage: at first by test, the storage battery that the amount of trying to please is bigger, with battery discharging only to 10.5V/, use constant voltage 14.8V/ only again, the method of current limliting 1.8A is charged, and the record charging voltage and current changes, and calculates electric current and is reduced to switching current (0.35～0.40A) time t1 (generally at 2.5～2.75 hours) from 1.2A, for guaranteeing full charge, determined time t (getting 3 hours) for good.
Under normal circumstances be inoperative in limited time, have only when storage battery is under the following bad charged state and just work:
Under the A hot conditions, charging current can't be reduced to switching current (0.35～0.40A) time, during in limited time to binding hours t, conversion by force.
The B-battery dehydration is more, internal storage battery oxygen recombination current is excessive surpass switching current (0.35～0.40A) time, during in limited time to binding hours t, conversion by force.
C since in the charger running data variation has taken place, charging voltage increases, make charging current can't be reduced to switching current (0.35～0.40A) time, during in limited time to binding hours t, conversion by force.
Situations such as micro-short circuit appear in the D internal storage battery, make charging current can't be reduced to switching current (0.35～0.40A) time, during in limited time to binding hours t, conversion by force.
The present invention has solved the greatest drawback of former common three-step charger effectively: it is " not changeing green light " phenomenon that charging is not transformed into the floating charge stage, and faults such as " thermal runaway ", distortion take place easily.
