Abstract

MPPT algorithms have been widely used in controllers of photovoltaic system. While for independent photovoltaic systems, researches focused on the charging method to batteries are still limited. Considering the power supply in continual rainy days, the capacity redundancy o batteries in photovoltaic system should be considered. However, it is difficult to fully charge these batteries at one time, which results that these batteries usually work in undervoltage conditions and then will be damaged in performance. Based on the characteristics of the batteries charging and discharging, a controller design combining battery fast charging and MPPT algorithm is proposed in this paper. Using the controller, not only MPPT function, but also protection on battery can be realized in photovoltaic systems. Furthermore, due to decrease of batteries maintenance cost, the comprehensive utilization efficiency of energy can be improved.
