Investigation of the Effect of Different Frequencies on Desulphation of Lead Acid Batteries by IoT Based Instrumentation System

Abstract

In this study, the solution of sulphation problem, which is often seen in Lead acid (LA) batteries, was focused on, and the effects of voltage pulses of different frequencies on the desulphation of LA batteries were experimentally investigated by using Internet of Things (IoT) based instrumentation circuits. To this end, four identical batteries, which were artificially sulphated under equal conditions, were charged by applying voltage pulses at different frequencies and DC voltage, and the changes in battery parameters were analysed. As a result of the analysis, it was seen that the decrease in the capacity of the batteries to transfer current to the load was high in the battery charged with DC voltage and relatively low in the batteries charged with voltage pulses of different frequencies. Thus, it is seen that desulphation process with high frequency voltage pulses affects a sulphated battery positively.

IoT Tabanlı Enstrümantasyon Sistemi ile Farklı Frekansların Kurşun Asit Akülerin Desülfasyonu Üzerine Etkilerinin İncelenmesi

Abstract

Bu çalışmada, Kurşun asit (KA) akülerde sıklıkla rastlanan sülfatlanma sorununun çözümüne odaklanılmış, nesnelerin interneti (IoT) tabanlı enstrümantasyon devreleri kullanılarak, farklı frekanslardaki gerilim darbelerinin KA akülerin desülfasyonu üzerindeki etkileri deneysel olarak incelenmiştir. Bu amaçla, eşit koşullarda sülfatlandırılmış dört özdeş akü, farklı frekanslarda gerilim darbeleri ve DC gerilim uygulanarak şarj edilmiş, akü parametrelerindeki değişimler analiz edilmiştir. Analiz sonucunda akülerin yüke akım aktarabilme kapasitelerindeki düşüşün, DC gerilim ile şarj edilen aküde yüksek oranda, farklı frekanstaki gerilim darbeleriyle şarj edilen akülerde ise nispeten daha düşük oranda olduğu görülmüştür. Buna göre, yüksek frekanslı gerilim darbeleriyle desülfasyon işleminin, sülfatlanmış bir aküyü olumlu şekilde etkilediği görülmüştür.
