| Abstract: | This paper makes a simple analysis on the factors influencing the aging of battery in photovoltaic system,and presents a new charge and discharge control strategy on the basis of this analysis.According to this control strategy,the whole charge process contains two stages:full-charge stage and pulse - charge stage.During the former stage,the battery is charged with the current that the photovoltaic system offers until its voltage reaches a value that is determined by the battery's state of charge (SOC),the charge current and the environmental temperature; while in the latter stage,the battery is charged within a voltage scope which is determined by the history of SOC(a week) .The experiment result proves that the application of this strategy can noticeably increase the battery's discharge capacity. |
