Embodiment Construction

[0021] Combine now figure 1 As shown, the detailed process of the large-capacity waste lead storage battery change combination pulse charging repair method of the present invention is described as follows:

[0022] 1. Use the combined pulse of the conventional duty cycle to charge until the charge is 65% to 75%.

[0023] At this stage, the combined pulse is charged and repaired with the large-capacity waste lead storage battery to be repaired with a large current according to the duty cycle of the conventional combined pulse positive and negative pulse charging time. This process is combined with the existing use The pulse charging method is the same. In the initial stage of charging and repairing, the terminal voltage of the battery increases with the increase of the storage capacity. Due to the existence of negative pulses and the low reduction rate of the battery plate material, there are few bubbles in the electrolyte.

[0024] 2. Increase the negative pulse charging tim...

Abstract

The invention discloses an accumulator charging technology and equipment, which is characterized by the following: 1) proceeding charging at 65-75 percent of combination pulse of normal positive and negative pulse charging time dutycycle; 2) increasing negative-pulse charging time in the combination pulse from 80-90 percent through new positive and negative pulse charging time dutycycle; 3) discharging the accumulator in the negative pulse charging condition; 4) repeating 1), 2), 3) charging and discharging courses until the accumulator voltage stabilizes over certain value of standard voltage to finish restoring. The invention can restore combination pulse charging waste lead accumulator of single positive and negative pulse dutycycle, which improves power utility rate.

Description

Technical field: [0001] The invention relates to storage battery charging technology, in particular to a method and equipment for charging and repairing large-capacity waste lead storage batteries by using the charging time of positive and negative pulses in variable combined pulses. Background technique: [0002] Lead storage battery is a kind of energy equipment widely used in various economic fields such as communication, electric power, railway, transportation, shipping, etc. Its varieties and models also vary according to the occasions and conditions of use. One of the current problems of lead-acid batteries is how to dispose of used batteries. If they are discarded at will, it will cause huge pollution to the environment and directly endanger human beings; if they are disassembled and returned to the furnace for regeneration, they will not only need special recycling technology, site, capital and other issues , there is also an environmental pollution problem. The inv...
