Research on Performance Capacity Recovery and Life Extension Technology of High Performance Sealed Lead-Acid Battery

A lead-acid battery repair instrument with output DC voltage and intermittent high-frequency resonant voltage pulse superimposed was designed in this paper. This paper describes the main composition and working principle of the equipment. The device uses a fixed voltage power supply and a high frequency resonance loop. By using the repair circuit, the lead sulfate crystals can generate high frequency harmonics and resonance. This causes it to dissolve into lead sulfate crystals of various sizes and shapes. Taking HCNR201 as the core, a single chip computer based on HCNR201 is used as the power supply to realize the detection of voltage and current. Adopted PWM modulation mode. It is proved that the device can repair the waste lead accumulator caused by vulcanization well.
