Abstract:A solar charge and discharge controller for regional automatic weather station is designed by using PIC16F676 microcomputer as control center and adopting essential periphery circuits.The circuit principle,implementation methods of various functions and software program diagram are introduced in detail.And the test results are given out.The controller is more suitable for solar power supply of regional automatic weather stations,because it overcomes the disadvantage that the battery is difficult to be filled under low temperature in winter and overcharge under high temperature in summer.The over discharge of battery is limited when it works at low current,which would prolong the service life of battery.
