A study of lead-acid battery efficiency near top-of-charge and the impact on PV system design

摘要: Knowledge of the charge efficiency Pb-acid batteries near top-of-charge is important to design small PV power systems. In order know how much energy required from photovoltaic array in accomplish task meeting load, including periodic full battery charge, a detailed knowledge charging as function state required, particularly high state-of-charge regime, systems are typically designed operate upper 20 30% state-of-charge. This paper presents results process for determining and discusses impact these findings on
