The combination of ampere-hour method and open-circuit voltage method in the photovoltaic measurement system is studied in this paper. In order to achieve the purpose of online measurement for remaining capacity, the influence of internal battery discharge and temperature on the battery capacity should be considered. The battery capacity decreases by the increasing charging times, and the increasing terminal voltage difference causes the inaccurate measurement of the capacity of battery. In this paper, two experimental measurement methods are employed, which are complementary to each other, to make the system measurement more accurate and extend the life of lead-acid batteries. If the charging process of photovoltaic system is unstable, an optimization of lead-acid battery applications in photovoltaic energy storage system is explored at the same time. Finally, an illustrative example is presented to demonstrate the effectiveness of the proposed measuring method.
