Design of Detection Device for Solar Photovoltaic Lighting System Charge-Discharge Performance
Based on virtual instrument technology the detection device of solar photovoltaic lighting system charge-discharge performance is designed, which can test eight parameters of solar cells power amp hours, battery charging amp hours, battery discharge amp hours, instantaneous power of solar cells power generation, instantaneous power of battery charge and discharge etc. The LabVIEW program controls data acquisition card, which realizes real-time data acquisition, display and storage etc. The parameters of the solar cells terminal voltage, the solar cells output current, the battery terminal voltage, the battery charge current and battery discharge current are tested. It contributes to the research of best match for solar cells and LED electrical properties, and provides technical parameters for battery reasonable using and battery life extended, and maximizes the performance of solar photovoltaic lighting system.
