摘要
Abstract
Based on the rapid development of solar photovoltaic technology,a quickly intelligent charging system based on MCU was designed;MSP430 type MCU was taken as the kernel control chip to realize the control of the battery charge;a new switch-mode charger member MAX77818 was chosen,then an application circuit was designed with charging input voltage of DC5 V and charging current of up to 3A.The PV input voltage and battery voltage were detected by two stage op-amp,using current sensing chip INA194 and second-order low-pass filter to measure the photovoltaic current and battery current,and the detection voltage and current were shown on the LCD monitor.This design is highly integrated,and enables fast charging with simple and stable circuit,which can be used in photovoltaic systems for various battery fast charging.关键词
