摘要:

储能设备充电系统是光伏发电系统的一个重要环节,其充电方法的选择对充电效果起决定性作用。文中设计了一种以STM32为主要核心处理器的充电系统,采用与MPPT算法相结合的新型智能充电方法对锂电池进行充电,此方法既可有效提高锂电池充电效率,又可防止电池过充。同时,具有过放电、过流、短路、温度保护及温度补偿等保护功能。

Abstract:

Energy storage device charging system is an important part of the photovoltaic power generation system,in which the selection of charging method plays a decisive role.This paper introduces a charging system based on taking STM32 as the main core processor,adopting a new type of intelligent charging method combined with MPPT algorithm to charge the device of energy storage.This method can effectively improve the charging efficiency of lithium batteries while preventing the battery overcharging with such functions as overdischarging,overcurrent,shortcircuit and temperature protection and temperature compensation.

Key words: MPPT;energy storage;STM32;photovoltaic power generation system
