| Abstract: | To solve the problems of low charging efficiency and single output of the stand-alone photovoltaic power systems for automatic weather stations,and improve the power efficiency,a new photovoltaic controller with the output of plus or minus 12V was designed by means of bq24610 chip and ATmega16L microcontroller.The controller can execute real-time detection of battery voltage,uses reasonable and accurate battery charge and discharge control strategies for charge and discharge,and has the protection functions of battery overcharge,overdischarge and anti-charge.It can effectively protect the batterys and extend the service life of batterys.Through experimental testing and practical application,the rationality of controller design and system stability are validated. |
