Array of solar photovoltaic system battery control system design

摘要

In order to improve the reliability of solar photovoltaic systems,photovoltaic systems is proposed on a single set of batteries battery array to implement the independent charge and discharge control,the capacity to predict and control the design,photovoltaic power generation system is equipped with a large number of the battery array,Set a separate control network infrastructure,microcontroller system,and then configure each battery control module of a child,many of the working group formed by micro-controller group,through the control bus interface,as will be a simple string batteries connected together in parallel array's on a cleverly integrated into the micro-controller system.This design solves the battery array of individual parameters for multiple sets of batteries battery performance difference leaving the problem of declining overall performance of the array.Thus realized enhanced the reliability of photovoltaic power generation system.
