METHOD OF REMOVING LEAD SULFATE FILM OF LEAD ACID BATTERY ELECTRODE AND PULSE GENERATOR FOR REMOVING LEAD SULFATE FILM

摘要

A method and device for removing a lead sulfate film. The method comprises a film decomposition step of repeatedly giving a first pulsed electric energy negative to battery charging and a second pulsed electric energy positive to battery charging. In a first sub-step, the first and second electric energy is given in the form of pulses at a repetition rate of 8 to 16 kHz, and the second electric energy is given with a delay time shorter than a quarter of the repetition interval after the first electric energy, or given continuously as negative electric energy. In a second sub-step, positive pulsed electric energy is continuously given. The first and second sub-steps are repeated alternately one or more times.
