Rapid Charge System for Lead-Acid Battery of Solar Energy Street Light based on Single-Chip Microcomputer

In view of the phenomenon that present solar energy street lamp control system is not full of protection to accumulator. This paper proposed the method of charge and discharge depolarization with entire process of pulse to lead-acid battery which has avoid the accumulator not discharge, lengthened the accumulatorpsilas life, and enhanced the solar streetlight system´s reliability. A simple rapid charging and discharging system adapt to lead-acid batteries with the low-power single-chip microcomputer P87LPC767 as the core of control loop is also designed.
