Description
The technical field is as follows:
the invention belongs to an accessory device of a lead-acid storage battery (hereinafter referred to as a battery), and particularly relates to an intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life charger for a storage battery.
Background art:
most of the battery chargers popular in the market at present adopt intelligent chargers formed by a switching power supply, and the charger has the biggest defect that the capacity of the battery cannot be truly full and sufficient, because the charging voltage designed by the charger is far lower than the high-voltage charging standard required in the later stage of battery formation charging before the battery leaves a factory; the battery formation charging is only carried out once before the battery leaves a factory, a large amount of bubbles are generated in the battery every time the formation charging reaches the continuous high-voltage charging stage at the later stage, and the temperature of the battery can be greatly increased to the high temperature of 48-56 ℃. The battery cannot be fatally damaged by one-time continuous high-voltage and high-temperature charging before the battery leaves a factory, but the battery cannot be continuously charged at high voltage and high temperature by vast users in a month and day, and if the battery is directly damaged; in order to fully charge and fully charge the battery and prolong the service life of the battery, people have thought of many methods, but so far, no charger dares to lead the majority of users to carry out high-voltage standard charging before leaving factories in months and days; the user adopts continuous low-voltage charging for a long time, and the long-term charging shortage of the battery is inevitably caused; the running mileage of the electric vehicle charged once is shortened, the vulcanization speed of the battery is accelerated, and the service life of the battery is greatly shortened.
The invention content is as follows:
a charger voltage change generating circuit and a reverse pulse discharging load F are connected in parallel between the positive electrode and the negative electrode of the output end of a charger consisting of a switching power supply, and a voltage change signal generated by the charger voltage change generating circuit is used for controlling the end potential of a reference voltage-stabilizing tube R in a charger circuit to enable the reference voltage-stabilizing tube R to change in a high-low alternating manner so as to enable the charger to synchronously output a charging voltage which changes in a high-low alternating manner; the high voltage output by the charger greatly exceeds the originally designed charging termination voltage of the charger, and the low voltage output by the charger is equal to the originally designed charging termination voltage of the charger, so that the charger automatically converts the battery charging to intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing charging when the battery pack terminal voltage exceeds the designed low charging voltage in the later period, and the intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life charger for the storage battery is formed.
The technical scheme of the invention is as follows:
a kind of lead-acid battery intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life charger connects a charger voltage change generating circuit and a reverse pulse discharging load F in parallel between the positive and negative poles of the charger output end formed by the switch power supply, the voltage change signal generated by the charger voltage change generating circuit controls the end potential of the reference voltage-stabilizing tube R in the charger circuit to make it change alternately in low and high, so as to realize the voltage output by the charger changing alternately in high and low cycles; the output neglect high voltage standard of the charger adopts the high voltage charging standard required in the later stage of battery formation charging in the manufacturing process of the lead-acid storage battery, namely the output neglect high voltage of a single body of the charger must be stabilized above 2.6V, taking a 48V charger pool as an example, the output neglect high voltage of the charger must be stabilized above 62.4V; the low voltage standard is designed to be equal to the originally designed charging termination voltage of the charger; and the output voltage of the chargers with other specifications is higher, lower and the like.
Description of the drawings:
fig. 1 is a diagram showing the specific connection position of the intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life charger of the storage battery, in which a charger voltage change generating circuit, a reverse pulse discharging load F and a voltage change signal control charger circuit are connected in parallel between the positive electrode and the negative electrode of the output end of the charger formed by a switching power supply, and the end potential of a reference voltage-stabilizing tube R in the charger circuit is controlled.
The specific implementation mode is as follows:
an intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life charger for a storage battery is shown in fig. 1, wherein a positive electrode and a negative electrode of a charger voltage change generating circuit and two ends of a reverse pulse discharging load F are respectively connected with a positive electrode and a negative electrode of an output end of the charger; the output end of a voltage change signal generated by the charger voltage change generating circuit is connected with the R end of a reference voltage-stabilizing tube in the charger circuit, and when the charger works, the voltage change signal generated by the voltage change generating circuit is used for controlling the R end of the reference voltage-stabilizing tube to enable the R end of the reference voltage-stabilizing tube to change cyclically with high and low cycles, so that the charger is enabled to synchronously output the charging voltage changing cyclically with high and low cycles; the charger output voltage is designed to be the high-voltage charging voltage required by the lead-acid storage battery in the later formation charging period before leaving factory, namely the monomer voltage in the later formation charging period must be stabilized to be more than 2.6V, and by taking a 48V charger as an example, the charger output voltage is designed to be no-load to be more than 62.4V; the output voltage of the charger is designed to be equal to the originally designed charging termination voltage of the charger, and the output voltage of intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing long-life chargers of other specifications and models is similar to the output voltage standard.
When the battery is charged by the charger to the later stage, the voltage of the battery pack exceeds the suddenly low voltage output by the charger, the battery pack is automatically converted into the intermittent high-low voltage reverse pulse mode of the second stage of the alternate lighting and cyclic turnover of the traffic light; at the moment, the charger charges the battery for a moment, stops charging the battery for a moment, and performs charging and stopping, and repeating and circulating repeatedly; when the charging is stopped, the battery pack voltage exceeds the suddenly low voltage output by the charger, so that the storage battery discharges to the reverse pulse discharging load F and the voltage change generating circuit at the output end of the charger; the invention eliminates bubbles generated by high-voltage charging and concentration polarization voltage formation which hinders the high-voltage charging in time through the reverse pulse discharging function when the charging is stopped intermittently, avoids bubbles generated by a large amount of electrolyzed water in the battery and the temperature rise of the battery, and protects the smooth high-voltage capacity-increasing and capacity-stabilizing charging; the intermittent high-low voltage reverse pulse charging mode can be used for formation charging before the lead-acid storage battery leaves factory, overcomes the defects that bubbles formed by a large amount of electrolyzed water generated in the battery and the temperature of the battery greatly rises to 48-56 ℃ due to continuous high-voltage charging in the later period of formation charging of the battery, and improves the formation charging efficiency of the battery and the actual capacity of the battery when leaving factory; meanwhile, the method can be used for safe and efficient repair and renovation of the battery with reduced capacity by vast users after the battery leaves factory and for capacity-increasing and capacity-stabilizing charging of the battery for a long time in the year of adulthood, thereby exponentially prolonging the service life of the battery.
The charger generally charges the battery in two stages, wherein the charging in the first stage is basically the same as the process of charging the indicating lamp from red to green by the continuous low-voltage chargers with various specifications and models in the current market; the charger of the invention automatically converts into intermittent high-low voltage pulse-back capacity-increasing and capacity-stabilizing charging at the second stage immediately, and the physical phenomenon of the intermittent high-low voltage pulse-back capacity-increasing and capacity-stabilizing charging is as follows:
1. the change rule of the charging indicator lamp is as follows: after the intermittent high-low voltage reverse pulse capacity-increasing and capacity-stabilizing charging is started, the charging indicator light is automatically changed from a red light to a green light, then the green light is changed to the red light, and the traffic light is alternately lightened and circularly turned over; when the lamp is turned over for a period, the red lamp stays for about 2 seconds after the red lamp appears, the green lamp stays for about 0.4 second after the green lamp appears, after intermittent high-low voltage pulse-reversal capacity-increasing and capacity-stabilizing charging is continuously carried out, the stay time of the red lamp after the red lamp appears is gradually shortened, the stay time of the green lamp after the green lamp appears is gradually prolonged, and finally, all the green lamps can be turned to the green lamps, and all the green lamps cannot be turned to the green lamps in some cases.
2. Change rule of charging current: the current gear of the digital multimeter is connected in series in the output loop of the charger, and the change rule of the intermittent high-low voltage reverse pulse capacity-increasing capacity-stabilizing charging current is observed: in the second stage intermittent high-low voltage reverse pulse capacity-increasing and capacity-stabilizing charging process, when a red light is lightened, the current reading of the multimeter is displayed: the charger still charges the battery with the first-stage charging current intensity; after intermittent high-low voltage reverse pulse capacity-increasing and capacity-stabilizing charging is continuously carried out, the staying time after the red light appears is gradually shortened, the current charging time into the battery is gradually shortened, and the intensity is also gradually reduced; the green light is quickly discharged to a charger discharging load F and a charger voltage change generating circuit from the storage battery after the green light appears, and finally, the charging and discharging balance is achieved; the discharge completely opposite to the direction of charging the storage battery by the charger is called reverse pulse discharge, and the design of the current intensity of the reverse pulse discharge is increased and decreased according to the rated capacity of the battery pack.
3. Battery temperature change law: the battery temperature in the whole process of intermittent high-low voltage reverse pulse capacity-increasing and capacity-stabilizing charging can not be changed due to the existence of high-voltage charging.
4. Battery capacity change rule: the charger of the invention is adopted to charge the new battery which is still discharged after continuous high-voltage formation charging for three times, so that the capacity of the new battery can be increased by about 10 percent on average; the old battery which is not scrapped for more than half a year or so is charged three times by using the continuous low-voltage charger, and the capacity of the old battery can be improved by more than 1 time on average.
By adopting the novel intermittent high-low voltage reverse pulse charging process, the formation charging efficiency of the lead-acid storage battery before leaving factory can be greatly improved; and the lead-acid battery charging system can be used for charging batteries with qualified indexes for a long time after the batteries leave factories, so that the charging and discharging capacity of the lead-acid battery is stabilized, and the service life of the battery is prolonged exponentially.
