Abstract

The variable-frequency battery revitalizing device contains a pulse generation circuit, a frequency generation circuit, a voltage detection circuit, and a frequency control circuit. A lead-acid battery to be revitalized is connected to the pulse generation circuit without being taken off duty and provides electricity to the battery revitalizing device. The voltage detection circuit senses the voltage of the battery being revitalized and produces an appropriate control signal to the frequency control circuit, which in turn determines the frequency of the clock signal produced by the frequency generation circuit. The clock signal drives the pulse generation circuit to produce pulses at the desired frequency and apply the pulses to the battery, thereby completing a feedback loop to automatically adjust the frequency of the pulses applied to the battery.
